Decred Journal — June 2018

Note: You can read this on GitHub, Medium or old Reddit to see the 207 links.

Development

The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response.
dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage.
Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun.
Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal.
Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue.
dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues.
Ticket splitting: 11-way ticket split from last month has voted (transaction).
Ethereum support in atomicswap is progressing and welcomes more eyeballs.
decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page.
decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here.
Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)

Network

Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s.
F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%.
Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak).
Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1.
Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).

ASICs

Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target.
Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.comtranslated, also on asicminervalue)
dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.

Integrations

bepool.org is a new mining pool spotted on dcred.eu.
Exchange integrations:
Two OTC trading desks are now shown on decred.org exchanges page.
BitPro payment gateway added Decred and posted on Reddit. Notably, it is fully functional without javascript or cookies and does not ask for name or email, among other features.
Guarda Wallet integrated Decred. Currently only in their web wallet, but more may come in future. Notable feature is "DCR purchase with a bank card". See more details in their post or ask their representative on Reddit. Important: do your best to understand the security model before using any wallet software.

Adoption

Merchants:
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project).
The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below.
Arbitrade is now mining Decred.

Media

stakey.club: a new website by @mm:
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
@morphymore translated Placeholder's Decred Investment Thesis and Richard Red's write-up on Politeia to Chinese, while @DZ translated Decred Roadmap 2018 to Italian and Russian, and A New Kind of DEX to Italian and Russian.
Second iteration of Chinese ratings released. Compared to the first issue, Decred dropped from 26 to 29 while Bitcoin fell from 13 to 17. We (the authors) restrain ourselves commenting on this one.

Community Discussions

Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository.
An update on our communication systems:
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS.
A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people.
A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred.
"Against community governance" article was discussed on Reddit and #governance.
"The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here.
Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms.
Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.

Markets

DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market.
In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.

Relevant External

Obelisk announced Launchpad service. The idea is to work with coin developers to design a custom, ASIC-friendly PoW algorithm together with a first batch of ASICs and distribute them among the community.
Equihash-based ZenCash was hit by a double spend attack that led to a loss of $450,000 by the exchange which was targeted.
Almost one year after collecting funds, Tezos announced a surprise identification procedure to claim tokens (non-javascript version).
A hacker broke into Syscoin's GitHub account and implanted malware stealing passwords and private keys into Windows binaries. This is a painful reminder for everybody to verify binaries after download.
Circle announced new asset listing framework for Poloniex. Relevant to recent discussions of exchange listing bribery:
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss.
Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance".
Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case.
Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too?

About This Issue

This is the third issue of Decred Journal after April and May.
Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research.
The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue.
As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations.
Credits (Slack names, alphabetical order): bee and Richard-Red. Special thanks to @Haon for bringing May 2018 issue to medium.

Obelisk's Sia ASICs - Full Details

https://obelisk.tech
Sia is releasing a 28nm, full-custom ASIC. This ASIC will be a complete package, similar to an antminer. You will receive a mining box that includes chips, power supplies, etc. Minimal setup will be required to get the miner working.
The miner is in early development already. We have begun the process of chip design, hardware design, and supply chain management. We have had conversations with previous ASIC manufacturers, and we have been warned about delays, unexpected costs, and myriads of pitfalls that throw off estimations. For this reason, we have set a conservative shipping date of June 2018. If the miners are ready sooner, they will be shipped sooner. If all goes well (and it rarely does, especially for first time manufacturers), we could see the miners shipping before March 2018.
Following the presale, we will be posting a development roadmap on our website that includes all the major steps of development. We will be crossing off steps in the roadmap as we complete them, which will allow the community to follow our progress, have visibility into delays, and will be able to see the places where we are ahead of or behind schedule.
The estimated hashrate is 100 GH/s. We will not know the exact hashrate until later in the development process, however we have confidence that 100 GH/s is a low bar to hit. We may end up shipping miners with a much higher hashrate, and will continue updating the estimated hashrate as we get more accurate estimates for how the chips will perform. The estimated power draw is 500w, though it may be significantly less.
The price of the unit is going to be $2499. Chip manufacturing is expensive, supply chains are expensive, and there are a lot of single-time costs that go into making miners. Future batches will likely have lower prices, however they will also ship later.
We will be selling the miners for Bitcoin. We expect the sale volume to be very large (in the tens of millions of dollars), and we feared that the Sia cryptocurrency would not have enough liquidity to handle all of that volume, resulting in the price rising quickly as people scramble to buy Siacoin for the ASIC, and then the price falling quickly as we convert the Siacoin to USD. This is the worst of both worlds - participants buy the siacoin at a premium, and then we sell them at a discount. Bitcoin has much, much deeper liquidity, and we can sell large volume of Bitcoin quickly without moving the price too much.
We will be converting the Bitcoin to USD as fast as possible. If the price fluctuates by more than 5% before we are able to convert, we will need to request more coins to cover the difference, or cancel the order. If the price fluctuates upwards by more than 5% before we convert, we will return the difference.
The sale and shipment of ASICs on the Sia network is going to dramatically increase the hashrate. When considering how much revenue you may get from a unit, please take into account the fact that we are selling enough units to potentially 10x or 100x the difficulty. If another ASIC manufacturer decides to start selling Sia ASICs, the hashrate may go up by more than just the number of units we sell. Please also consider that the block reward is decreasing. Today, the block reward is about 189,000 siacoins per block. By June 2018, our ship date, the block reward is going to be closer to 135,000 siacoins per block, decreasing by 1 siacoin per block (or 4320 siacoins per month).
The presale will be open for 7 days. There is no rush - people who buy on the fourth day will receive the same treatment as people who buy on the first day. The sale will not close early, and while we reserve the right to deny purchases, we have chosen not to put a cap on the number of units sold. We may pre-sell additional batches before the first batch ships. The first batch will have priority when we begin shipping, and if the later batches will be shipping shortly after, those later batches will be sold at a higher price. People who buy in on the first batch will receive both price preference and shipping date preference as a reward for taking on the most risk.
Obelisk is the company that will be producing these chips. Obelisk is a fully owned subsidiary of Nebulous Inc. Nebulous is the company that employs all of the Sia core developers.
Obelisk has plans for growth in the future. None of these plans are finalized as we are primarily focusing on shipping this miner, but potential future products include:
Finally, we plan to introduce decentralized mining pools into the Sia ecosystem before we ship the miners. Hosts will have the option of running their own mining pool, and then miners can detect the hosts by checking the blockchain and the peer network, forming payment channel contracts with them and participating in fully decentralized mining. This should help alleviate the pool centralization that is seen in most PoW cryptocurrencies.
We are very excited about our new company, and hope that you share in our excitement. Feel free to ask any questions.

Try reopen your dispute with Visa card under condition 13.5

The terms of sale were misrepresented for a transaction involving the following merchant types such as:

For your convenience, here's a template letter to your bank, feel free to modify and use.

Dear Madam or Sir,

I would like to provide documents to support the dispute against HashCoins LP(dba Hashflare, Merchant). I purchased a digital service(bitcoin mining) from the Merchant under the agreement of Terms of Service. Invoices are attached. You may find the Terms of Service at the merchant’s official website at https://hashflare.io/terms/.

  1. HashCoins significantly misrepresented the service on their website and in the Terms of Service on the following grounds.

1.1 “Fixed” Fees
On its official website www.hashflare.io (see Attached screenshot), above the "Purchase" section, HashCoins promises to charge “FIXED FEES” and “No hidden fees or commissions.” Maintenance fees are listed as “$0.005/ 1 MH/s / 24h” for SCRYPT cloud mining and “$0.0035 / 10 GH/s / 24h” for SHA-256 at the time of my purchase. All fees are shown in USD currency. HashCoins purposely points out that the fee is in “$” and says it’s fixed. In the Terms of Service, Section 11.1 on Page 9, they continue to show the fees are measured in USD (measure in USD / kWh, highlighted and quoted below):

F = A * q * S * 720 h, where:
A - actual hashrate, measured in H/s;
q - power consumption (powehashrate), measured in kW / H/s;
S - electricity cost (average for 2 previous months), measure in USD / kWh;
720 h - hours in 1 month (accounted as 30 days).

However, they never disclosed that they charge “fees” in BTC (Bitcoin currency) NOT in USD. And since the exchange rate of BTC/USD varies every day, the fees are in fact variable. Without given this information, HashCoins made customers believe that the contract will be profitable for the most of the time using their formula and the profitability will not be affected by the exchange rate. In retrospect, if the maintenance fees were in BTC, their contracts would be extremely unlikely to be profitable and their service is worthless.

By contrast, other merchants in the industry all fully disclose how they handle the maintenance fee in details. For instance, Genesis cloud mining, who provides a similar service, informs their customers in their ads that “Please note that the fee is fixed in USD but deducted from the daily mining rewards in BTC. Please refer to the Terms of Service for further details.” (See attachment, Genesis cloud mining’s ad. Can be found on their homepage https://www.genesis-mining.com/pricing). Genesis also explained how the conversion works in their Terms of Service.

1.2 Refuse to allow customers to withdraw available payout

On the website, HashCoins highlights that their service allows “INSTANT WITHDRAWAL”(see Attached screenshot), and customers can “Choose the amount to withdraw and receive it instantly”. Now HashCoins does not allow customers to withdraw until their profit (after subtracting maintenance fees) reaches a minimum amount, they also require customers to go through a very tedious verification process before they can withdraw, not to mention this minimum amount is impossible to reach for any ordinary customers.

1.3 Misleading Revenue Forecast
To make matters worse, HashCoins displayed a misleading “Revenue Forecast” on user’s dashboard (See attached screenshot, HashCoins Revenue Forecast), in which the revenue doesn’t take into account the maintenance fees, instead they indicated that the revenue is the payout. This makes existing customers continue to believe that their digital mining service is profitable.

  1. HashCoins misrepresented its cancellation policy

Specifically, in Section 5, the cancellation and termination policy specifies that after the mining become unprofitable for 21 consecutive days, HashCoins will and must permanently terminate the contract. As a result, they should return my funds, which was prepaid for 1-year service.
Boris, One of HashCoins’ support team members, has confirmed with me the cancellation policy in his email on (Correspondence 1).
On July 24, 2018, after 21 consecutive days of being non-profitable, HashCoins sent me an email about the cancellation (Correspondence 2).
On July 28, 2018, HashCoins claimed that they would resume the mining service (Correspondence 3) even though mining had not been profitable since then. I have never received payout. HashCoins only uses the “continuation” of service as a way to avoid refund. This is breach of contract.
At this moment, I simply demand the merchant HashCoins to follow the Terms of Service, and to cancel and refund my prepaid funds. I have been paying Maintenance fees (See the log HashCoins attached) while they offered the service even though the fees was misrepresented in the advertising and Terms of Service, as explained later. There is no reason for HashCoins to continue withholding my prepaid funds.

Quoted from the Terms of Service (a copy is screenshot is attached):
  1. CONTRACT TERM
5.1. These Terms of Service are valid indefinitely, even after Account termination.
5.2. The Contract Term for HashFlare.io Cloud Machines is set to 1 year by default, unless stated otherwise. The Contract is valid while profitable (refer to section 5.5.), until expired or until terminated (refer to section 13), whichever comes first.
5.3. Contracts with a stated expiry date will end on the date of expiry and the Cloud Machine is stopped.
5.4. Pre-order Contracts that are not activated immediately on purchase will activate on the stated date.
5.5. The Mining process continues until said mining is profitable. This means the Mining process will stop if the Maintenance and Electricity Fees will become larger than the Payout. If mining remains unprofitable for 21 consecutive days the Service is permanently terminated (Hashrate type specific). During the consecutive 21 day period, Payouts and Fees will also be temporarily stopped. If during the suspension period, the Contract-related mining factors (such as the exchange rate and mining difficulty) that are outside of HashFlare’s control will change favorably, making mining profitable again, the Service will be unsuspended and contracts reactivated.
5.6. HashFlare reserves the right to change the launch date, Contract Term of any Contract.

In sum, HashCoins misrepresented the service and income possibility to customers meanwhile they failed to act in accordance with their terms of service customers agreed on. I find this merchant lacks integrity. I am not surprised to see many people complaining and filing chargebacks against them. You may find testimonies on Twitter, Google, Reddit oand other social media. I hope the chargeback can be resolved in my favor. Thanks again for your support!

Best of Buttcoin: 2014

There's been some fantastic work done in this subreddit spreading disinformation researching, criticising, and debunking bitcoin and its sacred cows over the past year, which I would like to celebrate.
So here's some posts I saved on bitcoin-related topics. But I started saving things too late... So if you have and/or remember any great posts from the past year, dig them up and post them here.
Also, unironically, maybe someone should start a buttcoin wiki

First, three pieces of investigative journalism from Buttcoin's top minds. Here Charlie_Shrem examines the environmental impact of bitcoin mining. Key finding: For every Bitcoin transaction, 47 kilograms of CO2 is released into the atmosphere from the miners alone.
Current hash rate: 261,900,382 GH/s
Number of transactions per day: 71,331
If we assume rather conservatively that 1GH/s = 1 watt on average, then this would mean 261,900,382W is being used to power the network. We can simplify this to 261,900 kW.
Some miners can do better than 1W per 1GH/s, but many if not most do worse (i.e. 2W per 1GH/s to 10W per 1GH/s).
Going by the figure of 0.527kg CO2 / kWh found on this page,
0.527kg CO2 x 261,900 kW x 24 hours = 3,312,511.2 kg CO2 per day
Now,
3,312,511.2 kg CO2 / 71,331 transactions = 46.44 kg CO2 per transaction
For comparison, even going by this Coindesk Article, an ATM produces daily 3.162kg in CO2 emissions.
0.25kwH x 0.527kg CO2 x 24 hours = 3.162kg/day.
That means that the carbon emission for one Bitcoin transaction is equivalent to about 15 ATMs processing perhaps hundreds or thousands of transactions in a day combined.

Earlier this month Frankeh abruptly interrupted remittance-focused annular onanism by issuing a challenge: to find a single instance where bitcoin works out cheaper than a fiat alternative. In case you need to ask... Nope.
Right, there's a bunch of circlejerking happening in /Bitcoin right now so I think it's time to cut through the bullshit one way or another.
Country to send money to.
The biggest remittance markets are China, Indian and the Philippines.
I believe that since /Bitcoin often gives the Philippines as an example of successful Bitcoin remittance then it is the perfect country to use in our challenge.
Country to send money from.
According to this wikipedia article Malaysia and Canada have the biggest expat Filipino communities. 900,000 and 500,000.
So I think we should do the calculations based on both countries.
The methodology
Most people are not paid in Bitcoin. This is a fact. So for our calculation you must start with fiat, and end in fiat. We're not doing these calculations based on future utility of Bitcoin (No, neo. I'm saying...), we're doing them on the current utility.
We will also be doing a bank to bank remittance, because that is nice an constant. We don't need to take into account pick up locations Bitcoin remittance allows and pick up locations normal remittance allows. They'll vary too much.
Time will also not be taken into account, as time doesn't actually matter when it comes to remittance. Now, Bitcoiners might shout about this particular rule but let me explain my logic behind this.
A foreign worker gets paid every Friday. They start the remittance process on the Friday and regardless of if it takes 0, 3, or 5 days their family back in their home country just needs to base their life around money coming in on remitters pay day + 0, 3, or 5 days. Time taken is of no real value when it comes to remittance. All that matters is that it consistently arrives on day x.
As such, any remittance services that take over 5 working days are to be ignored for the sake of this challenge.
The amount
The amount is going to be 25% of the average wage in each of the countries. This isn't extremely scientific because it doesn't particularly need to be, and the figures are hard to come by.
So 1826.75 MYR for Malaysia and 1,398 CAD for Canada.
Don't bother complaining about these, they're just examples.
Few more ground rules
  • We're going to be going from bank/bank card to bank regardless, so we're not interested in banking fees on either side. They will be the same regardless of Bitcoin or WU (for example)
  • It must be from local fiat to foreign fiat.. You can't palm off the conversion fee to the receivers bank to keep fees down.
  • Any remittance service can be used, as long as Bitcoin is involved for people fighting the Bitcoin corner and Bitcoin isn't used for people fighting the WU (or similar) corner.
  • You must go through the process and document all the fees for each. Fees to look out for are currency spreads, transaction fees on exchanges, etc

Finally a recent thread, but commendable all the same. Hodldown presents some research leading to facts overturning years of knowledge in the bitcoin wiki. Even us shills have been laughing at bitcoin's pathetic capability of 7 transactions per second. It turns out, we were out by at least a factor of 2:
The average number of transactions per block right now is: 665 transactions
The average block size is 0.372731752748842mb.
That means the average transaction is 0.00056049887mb. Which means 1mb of transactions (the limit) is 1784 transactions
Assuming a 10 minute block (a whole other can of worms) that means there is 10*60 seconds.
1784/600 isn't 7. It's a 2.97.
Bitcoin at a technical level can not handle even 3 transactions per second.

In one of the frequent bitcoin user invasions, PayingWithActualMone outlines why the "solution in search of a problem" isn't that great of a solution to much either.
On the transaction side: the Bitcoin community seems convinced that banks are ripping them off (which imo they are not), and that it can be fixed by applying some magicsauce over a transaction that is facilitated by banks regardless. So far in practice I haven't seen any evidence of the 'fast' 'cheap' and 'easy' transactions, like most recently with Mollie. They usually compare the fees of BTC>BTC transactions to the fees of Chase Mastercard > a fucking nomad in the Sahara (with consumer protection) to prove their point. The community also seems convinced that the entire world banks the way America does, not realizing that in Europe banking has been dirt cheap for years.
And the security... oh boy the security. Half the population can't manage to go without a virus for one year (not an actual statistic), and now you expect them to secure their coins? People are dumb as shit, and software is always one step behind the exploits. We could of course create Bitcoin banks, but then there isn't much left of the original idea.
On the 'intrinsic value' side: what the hell is wrong with people. If the underlying product is no good in any aspect, why is it worth much? Right now (that's like 5 years after introduction mind you) BTC is used in 3 types of transactions: Silk Road, SatoshiDice & extremely questionable transactions. It does its job well in that aspect, and that's all it will ever be. The community just turned the technology into a giant ponzi, and they don't care as long as they get paid. The people actually doing business in Bitcoin probably don't care about the price that much.

Someone who deleted their account, on the argument that merchant adoption is a cause of the price drop:
That's just an excuse butters use for the price going down.
There's no real difference between selling bitcoin for fiat and exchanging bitcoin for goods and services. Both are a form of sale of bitcoin, an expression of preference for something other than bitcoin.
If on balance, there's more flow of bitcoin into fiat, goods or services than there is a corresponding opposing flow, then it is simply the market expressing the view that bitcoin is overvalued. Therefore, the reduction in the value of bitcoin (as valued in fiat) is a sincere expression of the market's view of what the correct price for bitcoin is.
Think of an example: A true believer has 20 BTC. He exchanges 10 BTC with Dell for a whizzy server. Dell (or another intermediary) sell the 10 BTC at an exchange in return for fiat. The market price of BTC goes down.
The price goes down, simply because a true believer cut his bitcoin holding, he got out. He thought having a server now was worth more to him than 10 tickets to the moon. Which is an expression of a negative view of the future value of bitcoin. A simple "aggressive" sale in trading parlance.

A late entry from jstolfi. A concise description of the Satoshi/Bitcoin origin story .
My understanding is that "Satoshi" had been trying to solve the technical problem of convincing a bunch of anonymous, volunteers to maintain and protect a distributed ledger, with no central authority.
He thought that he had a solution, in the form of a protocol that included PoW, miner rewards, longest chain, etc. The solution seemed to work on paper; but, as a good scientist, he started an experiment in order to check whether it would also work in practice.
For that experiment to be meaningful, it would have been enough if the coin was mined for several years only by a few hundred computer nerds, with the cooperation of some friendly pizza places and bars.
The US$ price of the coin was not important to the experiment, and it was never meant to be a weapon for libertarians, a way to buy drugs or evade taxes, a competitor to credit cards or Western Union, a sound investment or item for day-trading. All those "goals" were tacked onto it afterwards.

bob237 comments on the the absurdity of coinbase and it's touted 'rebuy' scheme,
It gets even better than that, actually. A lot of bitcoiners don't like 'losing' bitcoin, and so coinbase added a popular 'repurchase bitcoin' feature that automatically debits your bank account to replenish the BTC in your coinbase account after a purchase.
The ultimate result then is that you pay coinbase fiat, they take their cut, and then send that fiat on to the merchant. All 'bitcoins' used in the middle of the transaction are not really bitcoins, but just abstractions in coinbase's internal [off-chain] accounting system.
It's a crap version of paypal, no consumer protection and a ton of fees hidden in the spread when you buy your chuck-e-cheese tokens from them.

saigonsquare explains why ubiquitous tipping isn't the the killer app that it has been touted as, and why bitcoiners may fail to grasp this
Most people understand that there are different sorts of interaction. There are purely social interactions, there are quid-pro-quo interactions, and there are market interactions. Mixing those up causes embarrassment and insult. I wouldn't try to pay my mother-in-law ten bucks for cooking Christmas dinner, and I certainly wouldn't try to pay her ten cents. If a waiter suggests I try the raspberry tart, I won't get away with offering to bake him some cookies next week in compensation; if an office mate suggests I have a slice of her birthday cake, I'll be insulted if she brings me a bill for it. If I spend an hour helping my friend move apartments and he thanks me, I'm fine; we're friends helping each other out. If he pays me two bucks, I'm insulted; he's canceled the social nature of the interaction and instead simply bought my labor for a fraction of its going rate. I'm up two bucks but down a friend.
Ancapspergers, not particularly understanding any sort of interaction more complicated than buying a cheeseburger at Wendy's, assume that all interactions are a form of market transaction, and set pricing accordingly. Normal humans get offended by a penny shaving, because it cancels the social nature of the interaction and turns it into a market transaction--and then informs the recipient that his contribution to the transaction was of negligible value.

[b]What is GAG Cloud Tabot Mining?[/b]
[i]GAG Cloud Tabot Mining is a website dedicated to making Bitcoin mining easier to understand and more accessible for beginners. Cloud mining is the process of buying CPU power from dedicated data centers who use their own equipment to mine cryptocurrencies such as Bitcoin (BTC) on your behalf. It’s super simple - Your mining rigs are already set up and running. As soon as you’ve set up your account, you can start to mine your first coins using our Bitcoin cloud mining service! On a larger scale, we hope to contribute to the development of mining services and subsequently to the development, establishment and adoption of Bitcoin, both as a currency and as an economic system. This is an investment in high technologies with high risk. You are renting a computing technic for holding up the bitcoin meshwork.[/i]

[b]Why do we use it?[/b]
[i]The main advantage of this approach is that you don't need to have in-depth knowledge of mining hardware, nor buy expensive and hard-to-obtain devices. Renting 'hash power' (usually measured in Gigahertz per second or GH/s) also means you don't have to deal with the heat and noise that comes with a DIY mining project. Mining contracts are technically available for all major cryptocurrencies and you can visit your online dashboard at any time. The simple interface combined with GAG Cloud Tabot Mining's solid reputation has meant that at times the company cannot keep up with demand for mining contracts. We strongly believe that we can make mining affordable and profitable for everyone willing to join cryptocurrency revolution.
[/i]

[b]What methods of payment are accepted?[/b]
[i]Due to the owner's desire for anonymity and in order to stay within the law, direct deposit of funds by bank transfer isn't supported. You can, however, buy contracts with Bitcoin and via a lot of other cryptocurrencies.[/i]

[b]Why do we invest?[/b]
[i]Cloud mining is very profitable and i highly suggest it everyone doing so. You can recommend and invite friends also. You will receive an easy 5% for the whole amount your friends or clients will make. This only has pro’s and no con’s. Since you can referr friends and then invest so you wont have to make an think about it.[/i]

Good evening, I'm talking about this new cloud mining.

It was created by the GAG mining farm and the CEO is Italian.

No increase in difficulty and no maintenance costs. They are virtual mining contracts.

[img][[link]2 ]]([link]3 ])

[img][[link]4 ]]([link]5 ])

For now there are plans for BTC, ETH, LTC and BCH

[img][[link]6 ]]([link]7 ])

[img][[link]8 ]]([link]9 ])

[img][[link]10 ]]([link]11 ])

[img][[link]12 ]]([link]13 ])

When you buy the plan, for example, ETH tells you that you will take "0.001" a day but it is indicative ... In the sense the amount of ETH is always re-evaluated based on the equivalent value of the ROI that is daily

Proof of deposit

[img][[link]14 ]]([link]15 ])

If you want to test it: [[link]16

[b]Platform updates:[/b]

1) KYC (identity verification with file uploads and manual approval)

N.B. without completing the procedure you can not access the dashboard

2) Re-investment of the crypts matured directly on the platform

3) Automatic conversion EUR / Crypto and vice versa with automatic update every 2 minutes by taking the values from Coinmarketcap

4) Cost of the packs specified also in crypto

5) New payment method that allows you to use multiple types of crypto and that allows you to send multiple payments to complete the invoice (so you can also pay in round)

6) Daily ROI expressed in EUR and in crypto on the packs (this is also updated every 2 min)

7) Total Earnings at the end of the pack expressed both in EUR and in crypto (this too is updated every 2 min)

8) 2FA Google Authenticator

9) Limitations for withdrawals (min and max)

[b]Proof of Daily Return[/b]

[img][[link]17 ]]([link]18 ])

Out of pure curiosity I did a test of withdrawal ... I was told that the withdrawals are 100% manual for a security issue. They use high gas in fact it was almost instantaneous and the withdrawal fees are 3%

Decred Journal — May 2018

Note: New Reddit look may not highlight links. See old look here. A copy is hosted on GitHub for better reading experience. Check it out, contains photo of the month! Also on Medium

Development

dcrd: Significant optimization in signature hash calculation, bloom filters support was removed, 2x faster startup thanks to in-memory full block index, multipeer work advancing, stronger protection against majority hashpower attacks. Additionally, code refactoring and cleanup, code and test infrastructure improvements.
In dcrd and dcrwallet developers have been experimenting with new modular dependency and versioning schemes using vgo. @orthomind is seeking feedback for his work on reproducible builds.
Decrediton: 1.2.1 bugfix release, work on SPV has started, chart additions are in progress. Further simplification of the staking process is in the pipeline (slack).
Politeia: new command line tool to interact with Politeia API, general development is ongoing. Help with testing will soon be welcome: this issue sets out a test plan, join #politeia to follow progress and participate in testing.
dcrdata: work ongoing on improved design, adding more charts and improving Insight API support.
Android: design work advancing.
Decred's own DNS seeder (dcrseeder) was released. It is written in Go and it properly supports service bit filtering, which will allow SPV nodes to find full nodes that support compact filters.
Ticket splitting service by @matheusd entered beta and demonstrated an 11-way split on mainnet. Help with testing is much appreciated, please join #ticket_splitting to participate in splits, but check this doc to learn about the risks. Reddit discussion here.
Trezor support is expected to land in their next firmware update.
Decred is now supported by Riemann, a toolbox from James Prestwich to construct transactions for many UTXO-based chains from human-readable strings.
Atomic swap with Ethereum on testnet was demonstrated at Blockspot Conference LATAM.
Two new faces were added to contributors page.
Dev activity stats for May: 238 active PRs, 195 master commits, 32,831 added and 22,280 deleted lines spread across 8 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: rapid growth from ~4,000 TH/s at the beginning of the month to ~15,000 at the end with new all time high of 17,949. Interesting dynamic in hashrate distribution across mining pools: coinmine.pl share went down from 55% to 25% while F2Pool up from 2% to 44%. [Note: as of June 6, the hashrate continues to rise and has already passed 22,000 TH/s]
Staking: 30-day average ticket price is 91.3 DCR (+0.8), stake participation is 46.9% (+0.8%) with 3.68 million DCR locked (+0.15). Min price was 85.56. On May 11 ticket price surged to 96.99, staying elevated for longer than usual after such a pump. Locked DCR peaked at 47.17%. jet_user on reddit suggested that the DCR for these tickets likely came from a miner with significant hashrate.
Nodes: there are 226 public listening and 405 normal nodes per dcred.eu. Version distribution: 45% on v1.2.0 (up from 24% last month), 39% on v1.1.2, 15% on v1.1.0 and 1% running outdaded versions.

ASICs

Obelisk team posted an update. Current hashrate estimate of DCR1 is 1200 GH/s at 500 W and may still change. The chips came back at 40% the speed of the simulated results, it is still unknown why. Batch 1 units may get delayed 1-2 weeks past June 30. See discussions on decred and on siacoin.
@SiaBillionaire estimated that 7940 DCR1 units were sold in Batches 1-5, while Lynmar13 shared his projections of DCR1 profitability (reddit).
A new Chinese miner for pre-order was noticed by our Telegram group. Woodpecker WB2 specs 1.5 TH/s at 1200 W, costs 15,000 CNY (~2,340 USD) and the initial 150 units are expected to ship on Aug 15. (pow8.comtranslated)
Another new miner is iBelink DSM6T: 6 TH/s at 2100 W costing $6,300 (ibelink.co). Shipping starts from June 5. Some concerns and links were posted in these two threads.

Integrations

A new mining pool is available now: altpool.net. It uses PPLNS model and takes 1% fee.
Another infrastructure addition is tokensmart.io, a newly audited stake pool with 0.8% fee. There are a total of 14 stake pools now.
Exchange integrations:
OpenBazaar released an update that allows one to trade cryptocurrencies, including DCR.
@i2Rav from i2trading is now offering two sided OTC market liquidity on DCUSD in #trading channel.
Paytomat, payments solution for point of sale and e-commerce, integrated Decred. (missed in April issue)
CoinPayments, a payment processor supporting Decred, developed an integration with @Shopify that allows connected merchants to accept cryptocurrencies in exchange for goods.

Adoption

New merchants:
An update from VotoLegal:
michae2xl: Voto Legal: CEO Thiago Rondon of Appcívico, has already been contacted by 800 politicians and negotiations have started with four pre-candidates for the presidency (slack, source tweet)
Blockfolio rolled out Signal Beta with Decred in the list. Users who own or watch a coin will automatically receive updates pushed by project teams. Nice to see this Journal made it to the screenshot!
Placeholder Ventures announced that Decred is their first public investment. Their Investment Thesis is a clear and well researched overview of Decred. Among other great points it noted the less obvious benefit of not doing an ICO:
By choosing not to pre-sell coins to speculators, the financial rewards from Decred’s growth most favor those who work for the network.
Alex Evans, a cryptoeconomics researcher who recently joined Placeholder, posted his 13-page Decred Network Analysis.

Marketing

@Dustorf published March–April survey results (pdf). It analyzes 166 responses and has lots of interesting data. Just an example:
"I own DECRED because I saw a YouTube video with DECRED Jesus and after seeing it I was sold."
May targeted advertising report released. Reach @timhebel for full version.
PiedPiperCoin hired our advisors.
More creative promos by @jackliv3r: Contributing, Stake Now, The Splitting, Forbidden Exchange, Atomic Swaps.
Reminder: Stakey has his own Twitter account where he tweets about his antics and pours scorn on the holders of expired tickets.

Community Discussions

Community stats: Twitter 39,118 (+742), Reddit 8,167 (+277), Slack 5,658 (+160). Difference is between May 5 and May 31.
Reddit highlights: transparent up/down voting on Politeia, combining LN and atomic swaps, minimum viable superorganism, the controversial debate on Decred contractor model (people wondered about true motives behind the thread), tx size and fees discussion, hard moderation case, impact of ASICs on price, another "Why Decred?" thread with another excellent pitch by solar, fee analysis showing how ticket price algorithm change was controversial with ~100x cut in miner profits, impact of ticket splitting on ticket price, recommendations on promoting Decred, security against double spends and custom voting policies.
@R3VoLuT1OneR posted a preview of a proposal from his company for Decred to offer scholarships for students.
dcrtrader gained a couple of new moderators, weekly automatic threads were reconfigured to monthly and empty threads were removed. Currently most trading talk happens on #trading and some leaks to decred. A separate trading sub offers some advantages: unlimited trading talk, broad range of allowed topics, free speech and transparent moderation, in addition to standard reddit threaded discussion, permanent history and search.
Forum: potential social attacks on Decred.
Slack: the #governance channel created last month has seen many intelligent conversations on topics including: finite attention of decision makers, why stakeholders can make good decisions (opposed to a common narrative than only developers are capable of making good decisions), proposal funding and contractor pre-qualification, Cardano and Dash treasuries, quadratic voting, equality of outcome vs equality of opportunity, and much more.
One particularly important issue being discussed is the growing number of posts arguing that on-chain governance and coin voting is bad. Just a few examples from Twitter: Decred is solving an imagined problem (decent response by @jm_buirski), we convince ourselves that we need governance and ticket price algo vote was not controversial, on-chain governance hurts node operators and it is too early for it, it robs node operators of their role, crypto risks being captured by the wealthy, it is a huge threat to the whole public blockchain space, coin holders should not own the blockchain.
Some responses were posted here and here on Twitter, as well as this article by Noah Pierau.

Markets

The month of May has seen Decred earn some much deserved attention in the markets. DCR started the month around 0.009 BTC and finished around 0.0125 with interim high of 0.0165 on Bittrex. In USD terms it started around $81 and finished around $92, temporarily rising to $118. During a period in which most altcoins suffered, Decred has performed well; rising from rank #45 to #30 on Coinmarketcap.
The addition of a much awaited KRW pair on Upbit saw the price briefly double on some exchanges. This pair opens up direct DCR to fiat trading in one of the largest cryptocurrency markets in the world.
An update from @i2Rav:
We have begun trading DCR in large volume daily. The interest around DCR has really started to grow in terms of OTC quote requests. More and more customers are asking about trading it.
Like in previous month, Decred scores high by "% down from ATH" indicator being #2 on onchainfx as of June 6.

Relevant External

David Vorick (@taek) published lots of insights into the world of ASIC manufacturing (reddit). Bitmain replied.
Bitmain released an ASIC for Equihash (archived), an algorithm thought to be somewhat ASIC-resistant 2 years ago.
Three pure PoW coins were attacked this month, one attempting to be ASIC resistant. This shows the importance of Decred's PoS layer that exerts control over miners and allows Decred to welcome ASIC miners for more PoW security without sacrificing sovereignty to them.
Upbit was raided over suspected fraud and put under investigation. Following news reported no illicit activity was found and suggested and raid was premature and damaged trust in local exchanges.
Circle, the new owner of Poloniex, announced a USD-backed stablecoin and Bitmain partnership. The plan is to make USDC available as a primary market on Poloniex. More details in the FAQ.
Poloniex announced lower trading fees.
Bittrex plans to offer USD trading pairs.
@sumiflow made good progress on correcting Decred market cap on several sites:
speaking of market cap, I got it corrected on coingecko, cryptocompare, and worldcoinindex onchainfx, livecoinwatch, and cryptoindex.co said they would update it about a month ago but haven't yet I messaged coinlib.io today but haven't got a response yet coinmarketcap refused to correct it until they can verify certain funds have moved from dev wallets which is most likely forever unknowable (slack)

A long term outlook at the Dogecoin economy and currency (intro & pt 1 - mining power and a 51% attack) [meta]

Dogecoin is awesome. Dogecoin is too the moon!
But like any moon mission, it's worth asking the question what can go wrong on the way there. What stakeholders exist in the Dogecoin economy, what outcomes are possible in Dogecoin's journey, and how those outcomes could affect the behavior of the stakeholders.
This post is designed to encourage you to ask questions about every aspect of how Dogecoin functions. I do not intend this as investment advice in any sense of the word and have worked hard to avoid any discussion about what will happen to the price of dogecoin in the future.
In this post I will outline the stakeholders, outline the factors that affect the currency, and address the question of how Hashrate is related to miners decisions, and how it protects Dogecoin from a 51% attack
A few of the key facts I'll discuss:
Disclosure: I own a small amount of Dogecoin and Bitcoin (less than $100 in total at current market value) It's purely for entertainment and research purposes.
At the moment, I see the following people in the Dogecoin community:
  1. Long term investors (individuals holding Dogecoin either as a store of value or an investment opportunity)
  2. Short term investors (individuals holding Dogecoin as an investment opportunity)
  3. Professional Dogecoin miners (individuals choosing to mine Dogecoin rather than other Scrypt based coins, motivated by income)
  4. Community Dogecoin miners (individuals choosing to mine Dogecoin because they like Dogecoin, not motivated by income)
  5. Dogecoin buyers and sellers (individuals using dogecoin as a short term medium of exchange)
  6. Dogecoin community members (individuals holding Dogecoin for fun and/or using it for non-monetary compensation {irrelevant of market value}
  7. Dogecoin developers (Individuals who will decide what changes are made to the Dogecoin protocol {some of which may affect market behavior})
It's important to note that individuals in the community can be in more than one category (someone who holds dogecoin for short term investment can also buy and sell dogecoin on the market)
Variables which can affect the above stakeholders:
A. The average (and future) mining reward from a block of Dogecoin per kilohash hour. (How much can I make mining Dogecoin, what will Dogecoin inflation look like)
B. The total mining power (in GH) focused on Dogecoin vs other Scrypt coins (the more distributed miners, the safer the blockchain)
C. The price of Dogecoin/Market Cap (to determine if Dogecoin is worth mining)
D. The market perception about the future price of Dogecoin (to determine if Dogecoin is worth holding/spending and worth mining) {this is harder to quantify}
E. The Transaction volume of Dogecoin (to determine the community interest in the currency)
F. The reliability of Fiat to Dogecoin exchanges and Crypto to Dogecoin Exchanges (to facilitate an efficient/accurate market price for Dogecoin)
G. The speed of Dogecoin conversion into fiat (for instant transactions by merchants)
H. The development pipeline for new Dogecoin compatible mining hardware (how far off are ASICs for Scrypt)
As I see it, there's one major outcome that affects the entire community equally.
A 51% attack on Dogecoin would be of massive adverse value to everyone (except the individuals perpetrating the attack). If Dogecoin's blockchain was corrupted, It would cease to function as a useful medium of exchange and as a store of value. Miners would leave because the value would plummet from it not being trusted. Short term investors would dump their holdings as they started to lose value. Long term investors would do the same.
The currency would die.
How does one prevent a 51% attack? Have a large total mining hashrate in the hands of a diverse number of miners. If the cost of running a 51% attack is so high it's not worth the money, it won't happen.
This leads to a fundamental question: what keeps people mining Dogecoin?
Dogecoin miners are separated into two groups (as mentioned above), Professional miners who will go where they can make the most money, and amateur miners who will mine Dogecoin because they like the currency.
From a community health perspective, the professional miners are the main concern (with a few caveats). If professional miners leave, that affects trust in Dogecoin.
So what keeps them mining for us? There are two major Scrypt based cryptos out right now, Litecoin and Dogecoin, and the community, as of this writing, is essentially split 50/50 is split 55/45 in favor of Dogecoin.
What this reflects is that miners expect to make more money mining Dogecoin than litecoin. Since an efficient market exists for trading Litecoin into Bitcoin and Dogecoin into Bitcoin, it seems to this author that value should be assessed in terms of current actual value (that miners choose what coin to mine based on how much they can sell it for today)
Since two large scale profitable currencies exist (LTE and DOGE) miners are going to choose the more profitable up until the point where the two converge. This depends on three variables:
Difficulty, total hash rate, and average reward.
As of Jan 23, DOGE is a little over twice as profitable as LTC.
This is what has prompted the major switch of the past few days.
I need help modeling is how much total value comes from LTC and how much from DOGE (essentially, if I owned the entire mining pool and split my work equally, how much could I make from each currency?)
At some point, enough miners will leave LTC that it's difficulty will drop. Assuming LTC retains its value (in fiat), falling difficulty will make it more profitable. Eventually, its profitability will once again match that of Dogecoin, and miners will stop leaving LTC for DOGE.
The problem is that as miners leave, it is possible that the currency value will drop as well.
On Jan 20, LTC had a 115GH rate, Doge had 57GH. Doge was trading at .00003 LTC. On Jan 23, Doge had 95, LTC had 75, and Doge more than doubled in price to .0000675. (Litecoin has also dropped about $1 (~5%) in value in USD over the same period.)
This is likely why even though Dogecoin has more miners than LTC, Litecoin is still less profitable for Miners (at this precise moment). Dogecoin has increased in currency value more than it has decreased in mining value.
Thus, the fundamental question is what kind of change is required in the price of DOGE/LTC and what hashing ratio will LTC and DOGE settle on based on their current price. It's important to remember that LTC has not dropped in value significantly, Doge has simply rose dramatically.
Fundamentally, as long as LTC has some value, it will have some percentage of Scrypt hashing power devoted to it. The same is true for Doge. So as long as people still want both currencies to some degree, mining power will be split. *Depending on that split, Dogecoin will be safe if it has enough mining power to prevent a malicious third party, and if that mining power remains in the hands of a diverse group of DOGE mining pools. *
My next post will address the different needs of the Long term investor, the short term investor, and the casual owner. (Some want a long term stable currency, some want a dramatic increase in price (even if it hurts the currency long term)
Please feel free to leave comments about anything you disagree with, any changes I should make, any thoughts about other factors that could affect the health of the currency, any other subjects you'd like to see explored. Thanks!

Bitcoin mining, Antminer S9, $790 USD/month profit

Profit per month:
Disclosure: Mining metrics are calculated based on a network hash rate of 13,823,824,128 GH/s and using a BTC - USD exchange rate of 1 BTC = $ 16838.21. These figures vary based on the total network hash rate and on the BTC to USD conversion rate. Block reward is fixed at 12.5 BTC and future block reward reductions are not taken into account. The average block time used in the calculation is 600 seconds. The electricity price used in generating these metrics is $ 0.132 per kWh.
https://www.cryptocompare.com/mining/calculatobtc?HashingPower=14&HashingUnit=TH%2Fs&PowerConsumption=1372&CostPerkWh=0.132
Antminer S9 Specs:
https://shop.bitmain.com/antminer_s9_asic_bitcoin_miner.htm?flag=specifications
CryptoCompare shows a $790.46 USD profit per month with the following input:
1 BTC = $ 16838.21
Hasting power: 14
Power consumption (w): 1372
Cost per KW/h ($): 0.132
$790 USD/month is the total mined - total cost.
$790 is very profitable. Mining 0.05 BTC/month is very good when the current BTC price is $16k.
"According to the above inputs, the S9 will produce** 0.285 BTC / $159 per month** and 3.36 BTC / $1939 per year." - June 27, 2017 article
https://www.buybitcoinworldwide.com/mining/hardware/antminer-s9/
buybitcoinworldwide.com June 27, 2017 article shows only a profit of $159/month but BTC then was 1BTC = $2500USD.
Is it very profitable to run a bitcoin Antminer S9 now with profit of $790 USD/month?

IRC Log from Ravencoin Open Developer Meeting - Aug 24, 2018

[14:05] <@wolfsokta> Hello Everybody, sorry we're a bit late getting started
[14:05] == block_338778 [[email protected]/web/freenode/ip.72.214.222.226] has joined #ravencoin-dev
[14:06] <@wolfsokta> Here are the topics we would like to cover today • 2.0.4 Need to upgrade - What we have done to communicate to the community • Unique Assets • iOS Wallet • General Q&A
[14:06] == Chatturga changed the topic of #ravencoin-dev to: 2.0.4 Need to upgrade - What we have done to communicate to the community • Unique Assets • iOS Wallet • General Q&A
[14:06] <@wolfsokta> Daben, could you mention what we have done to communicate the need for the 2.0.4 upgrade?
[14:07] == hwhwhsushwban [[email protected]/web/freenode/ip.172.58.37.35] has joined #ravencoin-dev
[14:07] <@wolfsokta> Others here are free to chime in where they saw the message first.

[14:08] Whats up bois
[14:08] hi everyone
[14:08] hi hi
[14:08] <@wolfsokta> Discussing the 2.0.4 update and the need to upgrade.
[14:08] <@Chatturga> Sure. As most of you are aware, the community has been expressing concerns with the difficulty oscillations, and were asking that something be done to the difficulty retargeting. Many people submitted suggestions, and the devs decided to implement DGW.
[14:09] <@Tron> I wrote up a short description of why we're moving to a new difficulty adjustment. https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7
[14:09] <@Chatturga> I have made posts on discord, telegram, bitcointalk, reddit, and ravencointalk.org from testnet stages through current.
[14:10] <@Chatturga> If there are any other channels that can reach a large number of community members, I would love to have more.
[14:10] <@wolfsokta> Thanks Tron, that hasn't been shared to the community at large yet, but folks feel free to share it.
[14:10] When was this decision made and by whom and how?
[14:10] <@Chatturga> I have also communicated with the pool operators and exchanges about the update. Of all of the current pools, only 2 have not yet updated versions.
[14:11] <@wolfsokta> The decision was made by the developers through ongoing requests for weeks made by the community.
[14:12] <@wolfsokta> Evidence was provided by the community of the damages that could be caused to projects when the wild swings continue.
[14:12] So was there a meeting or vote? How can people get invited
[14:12] <@Tron> It was also informed by my conversations with some miners that recommended that we make the change before the coin died. They witnessed similar oscillations from which other coins never recovered.
[14:13] only two pools left to upgrade is good, what about the exchanges? Any word on how many of those have/have not upgraded?
[14:13] <@wolfsokta> We talked about here in our last meeting Bruce_. All attendees were asked if they had any questions or concerns.

[14:14] <@Chatturga> Bittrex, Cryptopia, and IDCM have all either updated or have announced their intent to update.

[14:15] what's the status here?
[14:15] I don’t think that was at all clear from the last dev meeting
[14:15] I can’t be the only person who didn’t understand it
[14:15] <@wolfsokta> Are there any suggestions on how to communicate the need to upgrade even further? I am concerned that others might also not understand.
[14:17] I’m not sold on the benefit and don’t understand the need for a hard fork — I think it’s a bad precedent to simply go rally exchanges to support a hard fork with little to no discussion
[14:17] so just to note, the exchanges not listed as being upgraded or have announced their intention to upgrade include: qbtc, upbit, and cryptobridge (all with over $40k usd volume past 24 hours according to coinmarketcap)
[14:18] <@wolfsokta> I don't agree that there was little or no discussion at all.
[14:19] <@wolfsokta> Looking back at our meeting notes from two weeks ago "fork" was specifically asked about by BrianMCT.
[14:19] If individual devs have the power to simple decide to do something as drastic as a hard fork and can get exchanges and miners to do it that’s got a lot of issues with centralization
[14:19] <@wolfsokta> It had been implemented on testnet by then and discussed in the community for several weeks before that.
[14:19] == under [[email protected]/web/freenode/ip.72.200.168.56] has joined #ravencoin-dev
[14:19] howdy
[14:19] Everything I’ve seen has been related to the asset layer
[14:19] I have to agree with Bruce_, though I wasn't able to join the last meeting here. That said I support the fork
[14:20] Which devs made this decision to do a fork and how was it communicated?
[14:20] well mostly the community made the decision
[14:20] Consensus on a change is the heart of bitcoin development and I believe the devs have done a great job building that consensus
[14:20] a lot of miners were in uproar about the situation
[14:20] <@wolfsokta> All of the devs were supporting the changes. It wasn't done in isolation at all.
[14:21] This topic has been a huge discussion point within the RVN mining community for quite some time
[14:21] the community and miners have been having issues with the way diff is adjusted for quite some time now
[14:21] Sure I’m well aware of that -
[14:21] Not sold on the benefits of having difficulty crippled by rented hashpower?
[14:21] The community saw a problem. The devs got together and talked about a solution and implemented a solution
[14:21] I’m active in the community
[14:22] So well aware of the discussions on DGW etc
[14:22] Hard fork as a solution to a problem community had with rented hashpower (nicehash!!) sounds like the perfect decentralized scenario!
[14:23] hard forks are very dangerous
[14:23] mining parties in difficulty drops are too
[14:23] <@wolfsokta> Agreed, we want to keep them to an absolute minimum.
[14:23] But miners motivation it’s the main vote
[14:24] What would it take to convince you that constantly going from 4 Th/s to 500 Gh/s every week is worse for the long term health of the coin than the risk of a hard fork to fix it?
[14:24] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has quit [Ping timeout: 252 seconds]
[14:24] This hardfork does include the asset layer right? if so why is it being delayed in implementation?
[14:24] <@wolfsokta> Come back Tron!
[14:24] coudl it have been implement through bip9 voting?
[14:24] also hard fork is activated by the community! that's a vote thing!
[14:24] @mrsushi to give people time to upgrade their wallet
[14:25] @under, it would be much hard to keep consensus with a bip9 change
[14:25] <@wolfsokta> We investigated that closely Under.
[14:25] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has joined #ravencoin-dev
[14:25] <@wolfsokta> See Tron's post for more details about that.
[14:25] <@spyder_> Hi Tron
[14:25] <@wolfsokta> https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7
[14:25] Sorry about that. Computer went to sleep.
[14:26] I'm wrong
[14:26] 2 cents. the release deadline of october 31st puts a bit of strain on getting code shipped. (duh). but fixing daa was important to the current health of the coin, and was widely suppported by current mining majority commuity. could it have been implemented in a different manner? yes . if we didnt have deadlines
[14:27] == wjcgiwgu283ik3cj [[email protected]/web/freenode/ip.172.58.37.35] has quit [Quit: Page closed]
[14:27] sushi this fork does not include assets. it's not being delayed though, we're making great progress for an Oct 31 target
[14:28] I don’t see the urgency but my vote doesn’t matter since my hash power is still CPUs
[14:28] <@wolfsokta> We're seeing the community get behind the change as well based on the amount of people jumping back in to mine through this last high difficulty phase.
[14:28] So that will be another hardfork?
[14:28] the fork does include the asset code though set to activate on oct 30th
[14:28] yes
[14:29] <@wolfsokta> Yes, it will based on the upgrade voting through the BIP9 process.
[14:29] I wanted to ask about burn rates from this group: and make a proposal.
[14:29] we're also trying hard to make it the last for awhile
[14:29] Can you clear up the above — there will be this one and another hard fork?
[14:29] <@wolfsokta> Okay, we could discuss that under towards the end of the meeting.
[14:30] If this one has the asset layer is there something different set for October
[14:30] <@wolfsokta> Yes, there will be another hard fork on October 31st once the voting process is successful.
[14:31] <@wolfsokta> The code is in 2.0.4 now and assets are active on testnet
[14:31] Bruce, the assets layer is still being worked on. Assets is active on mainnet. So in Oct 31 voting will start. and if it passes, the chain will fork.
[14:31] this one does NOT include assets for mainnet Bruce -- assets are targeted for Oct 31
[14:31] not***
[14:31] not active****
[14:31] correct me if I'm wrong here, but if everyone upgrades to 2.0.4 for this fork this week, the vote will automatically pass on oct 31st correct? nothing else needs to be done
[14:31] Will if need another download or does this software download cover both forks?
[14:31] <@wolfsokta> Correct Urgo
[14:32] thats how the testnet got activated and this one shows "asset activation status: waiting until 10/30/2018 20:00 (ET)"
[14:32] Will require another upgrade before Oct 31
[14:32] thank you for the clarification wolfsokta
[14:32] <@wolfsokta> It covers both forks, but we might have additional bug fixes in later releases.
[14:32] So users DL one version now and another one around October 30 which activates after that basically?
[14:33] I understand that, but I just wanted to make it clear that if people upgrade to this version for this fork and then don't do anything, they are also voting for the fork on oct 31st
[14:33] Oh okay — one DL?
[14:33] Bruce, Yes.
[14:33] Ty
[14:33] well there is the issue that there maybe some further consensus bugs dealing with the pruneability of asset transactions that needs to be corrected between 2.0.4 and mainnet. so i would imagine that there will be further revisions required to upgrade before now and october 31
[14:33] @under that is correct.
[14:34] I would highly recommend bumping the semver up to 3.0.0 for the final pre 31st release so that the public know to definitely upgrade
[14:34] @under +1
[14:35] out of curiosity, have there been many bugs found with the assets from the version released in july for testnet (2.0.3) until this version? or is it solely a change to DGW?
[14:35] <@wolfsokta> That's not a bad idea under.
[14:35] <@spyder_> @under good idea
[14:35] @urgo. Bugs are being found and fixed daily.
[14:35] Any time the protocol needs to change, there would need to be a hard fork (aka upgrade). It is our hope that we can activate feature forks through the BIP process (as we are doing for assets). Mining pools and exchanges will need to be on the newest software at the point of asset activation - should the mining hash power vote for assets.
[14:35] blondfrogs: gotcha
[14:35] There have been bugs found (and fixed). Testing continues. We appreciate all the bug reports you can give us.
[14:36] <@wolfsokta> Yes! Thank you all for your help in the community.
[14:37] (pull requests with fixes and test coverage would be even better!)
[14:37] asset creation collision is another major issue. current unfair advantage or nodes that fore connect to mining pools will have network topologies that guarantee acceptance. I had discussed the possibility of fee based asset creation selection and i feel that would be a more equal playing ground for all users
[14:38] *of nodes that force
[14:38] <@wolfsokta> What cfox said, we will always welcome development help.
[14:38] So just to make sure everyone know. When assets is ready to go live on oct 31st. Everyone that wants to be on the assets chain without any problems will have to download the new binary.
[14:39] <@wolfsokta> The latest binary.
[14:39] under: already in the works
[14:39] excellent to hear
[14:39] == UserJonPizza [[email protected]/web/freenode/ip.24.218.60.237] has joined #ravencoin-dev
[14:39] <@wolfsokta> Okay, we've spent a bunch of time on that topic and I think it was needed. Does anybody have any other suggestions on how to get the word out even more?
[14:40] maybe preface all 2.0.X releases as pre-releases... minimize the number of releases between now and 3.0 etc
[14:41] <@wolfsokta> Bruce_ let's discuss further offline.
[14:41] wolfsokta: which are the remaining two pools that need to be upgraded? I've identified qbtc, upbit, and cryptobridge as high volume exchanges that haven't said they were going to do it yet
[14:41] so people can help reach out to them
[14:41] f2pool is notoriously hard to contact
[14:41] are they on board?
[14:42] <@wolfsokta> We could use help reaching out to QBTC and Graviex
[14:42] I can try to contact CB if you want?
[14:42] <@Chatturga> The remaining pools are Ravenminer and PickAxePro.
[14:42] <@Chatturga> I have spoken with their operators, the update just hasnt been applied yet.
[14:42] ravenminer is one of the largest ones too. If they don't upgrade that will be a problem
[14:42] okay good news
[14:42] (PickAxePro sounds like a Ruby book)
[14:43] I strongly feel like getting the word out on ravencoin.org would be beneficial
[14:44] that site is sorely in need of active contribution
[14:44] Anyone can volunteer to contribute
[14:44] <@wolfsokta> Okay, cfox can you talk about the status of unique assets?
[14:44] sure
[14:45] <@wolfsokta> I'll add website to the end of our topics.
[14:45] code is in review and will be on the development branch shortly
[14:45] would it make sense to have a page on the wiki (or somewhere else) that lists the wallet versions run by pools & exchanges?
[14:45] will be in next release
[14:45] furthermore, many sites have friendly link to the standard installers for each platform, if the site linked to the primary installers for each platform to reduce github newb confusion that would be good as well
[14:46] likely to a testnetv5 although that isn't settled
[14:46] <@wolfsokta> Thanks cfox.
[14:46] <@wolfsokta> Are there any questions about unique assets, and how they work?
[14:47] after the # are there any charachters you cant use?
[14:47] will unique assets be constrained by the asset alphanumeric set?
[14:47] ^
[14:47] <@Chatturga> @Urgo there is a page that tracks and shows if they have updated, but it currently doesnt show the actual version that they are on.
[14:47] a-z A-Z 0-9
[14:47] <@Chatturga> https://raven.wiki/wiki/Exchange_notifications#Pools
[14:47] There are a few. Mostly ones that mess with command-line
[14:47] you'll be able to use rpc to do "issueunique MATRIX ['Neo','Tank','Tank Brother']" and it will create three assets for you (MATRIX#Neo, etc.)
[14:47] @cfox - No space
[14:48] @under the unique tags have an expanded set of characters allowed
[14:48] Chatturga: thank you
[14:48] @UJP yes there are some you can't use -- I'll try to post gimmie a sec..
[14:49] Ok. Thank you much!
[14:49] 36^36 assets possible and 62^62 uniques available per asset?
[14:49] <@spyder_> std::regex UNIQUE_TAG_CHARACTERS("^[[email protected]$%&*()[\\]{}<>_.;?\\\\:]+$");
[14:50] regex UNIQUE_TAG_CHARACTERS("^[[email protected]$%&*()[\\]{}<>_.;?\\\\:]+$")
[14:50] oh thanks Mark
[14:51] <@wolfsokta> Okay, next up. I want to thank everybody for helping test the iOS wallet release.
[14:51] <@wolfsokta> We are working with Apple to get the final approval to post it to the App Store
[14:51] @under max asset length is 30, including unique tag
[14:51] Does the RVN wallet have any other cryptos or just RVN?
[14:52] == BruceFenton [[email protected]/web/freenode/ip.67.189.233.170] has joined #ravencoin-dev
[14:52] will the android and ios source be migrated to the ravenproject github?
[14:52] I've been adding beta test users. I've added about 80 new users in the last few days.
[14:52] <@wolfsokta> Just RVN, and we want to focus on adding the asset support to the wallet.
[14:53] == Bruce_ [[email protected]/web/freenode/ip.67.189.233.170] has quit [Ping timeout: 252 seconds]
[14:53] <@wolfsokta> Yes, the code will also be freely available on GitHub for both iOS and Android. Thank you Roshii!
[14:53] Would you consider the iOS wallet to be a more secure place for one's holdings than say, a Mac connected to the internet?
[14:53] will there be a chance of a more user freindly wallet with better graphics like the iOS on PC?
[14:53] the android wallet is getting updated for DGW, correct?
[14:53] <@wolfsokta> That has come up in our discussion Pizza.
[14:54] QT framework is pretty well baked in and is cross platform. if we get some qt gurus possibly
[14:54] Phones are pretty good because the wallet we forked uses the TPM from modern phones.
[14:54] Most important is to write down and safely store your 12 word seed.
[14:54] TPM?
[14:54] <@wolfsokta> A user friendly wallet is one of our main goals.
[14:55] TPM == Trusted Platform Module
[14:55] Ahhh thanks
[14:55] just please no electron apps. they are full of security holes
[14:55] <@spyder_> It is whats makes your stuffs secure
[14:55] not fit for crypto
[14:55] under: depends on who makes it
[14:55] The interface screenshots I've seen look like Bread/Loaf wallet ... I assume that's what was forked from
[14:55] ;)
[14:56] <@wolfsokta> @roshii did you see the question about the Android wallet and DGW?
[14:56] Yes, it was a fork of breadwallet. We like their security.
[14:56] chromium 58 is the last bundled electron engine and has every vuln documented online by google. so unless you patch every vuln.... methinks not
[14:56] Agreed, great choice
[14:57] <@wolfsokta> @Under, what was your proposal?
[14:58] All asset creation Transactions have a mandatory OP_CHECKLOCKTIMEVERIFY of 1 year(or some agreed upon time interval), and the 500 RVN goes to a multisig devfund, run by a custodial group. We get: 1) an artificial temporary burn, 2) sustainable community and core development funding for the long term, after OSTK/Medici 3) and the reintroduction of RVN supply at a fixed schedule, enabling the removal of the 42k max cap of total As
[14:58] *im wrong on the 42k figure
[14:58] <@wolfsokta> Interesting...
[14:59] <@wolfsokta> Love to hear others thoughts.
[14:59] Update: I posted a message on the CryptoBridge discord and one of their support members @stepollo#6276 said he believes the coin team is already aware of the fork but he would forward the message about the fork over to them right now anyway
[14:59] Ifs 42 million assets
[14:59] yep.
[15:00] I have a different Idea. If the 500 RVN goes to a dev fund its more centralized. The 500 RVN should go back into the unmined coins so miners can stay for longer.
[15:01] *without a hardfork
[15:01] <@wolfsokta> lol
[15:01] that breaks halving schedule, since utxos cant return to an unmined state.
[15:01] @UJP back into coinbase is interesting. would have to think about how that effects distribution schedule, etc.
[15:01] only way to do that would be to dynamicaly grow max supply
[15:02] and i am concerned already about the max safe integer on various platforms at 21 billion
[15:02] js chokes on ravencoin already
[15:02] <@wolfsokta> Other thoughts on Under's proposal? JS isn't a real language. ;)
[15:02] Well Bitcoin has more than 21 bn Sats
[15:02] Is there somebody who wants to volunteer to fix js.
[15:02] hahaha
[15:03] I honestly would hate for the coins to go to a dev fund. It doesn't seem like Ravencoin to me.
[15:03] Yep, but we're 21 billion x 100,000,000 -- Fits fine in a 64-bit integer, but problematic for some languages.
[15:03] <@wolfsokta> Thanks UJP
[15:04] <@wolfsokta> We're past time but I would like to continue if you folks are up for it.
[15:04] Yeah no coins can go anywhere centrality contorted like a dev fund cause that would mean someone has to run it and the code can’t decide that so it’s destined to break
[15:05] currently and long term with out the financial backing of development then improvements and features will be difficult. we are certainly thankful for our current development model. but if a skunkworks project hits a particular baseline of profitability any reasonable company would terminate it
[15:05] Yes let’s contibue for sure
[15:05] the alternative to a dev fund in my mind would be timelocking those funds back to the issuers change address
[15:06] But we can’t have dev built in to the code — it has to be open source like Bitcoin and monero and Litecoin - it’s got drawbacks but way more advantages- it’s the best model
[15:06] Dev funding
[15:06] i highly reccommend not reducing the utility of raven by removing permanently the supply
[15:07] == BW_ [[email protected]/web/freenode/ip.138.68.243.202] has joined #ravencoin-dev
[15:07] timelocking those funds accompllishes the same sacrifice
[15:07] @under timelocking is interesting too
[15:07] How exactly does timelocking work?
[15:07] <@wolfsokta> ^
[15:07] I mean you could change the price of assets with the Block reward halfing.
[15:07] == Roshiix [[email protected]/web/freenode/ip.105.67.2.212] has joined #ravencoin-dev
[15:08] funds cant be spent from an address until a certain time passes
[15:08] but in a what magical fairy land do people continue to work for free forever. funding development is a real issue... as much as some might philosphically disagree. its a reality
[15:08] You’d still need a centralized party to decide how to distribute the funds
[15:08] even unofficially blockstream supports bitcoin devs
[15:08] on chain is more transparent imho
[15:09] == Tron_ [[email protected]/web/freenode/ip.173.241.144.77] has joined #ravencoin-dev
[15:09] @UJP yes there are unlimited strategies. one factor that I think is v important is giving application developers a way to easily budget for projects which leads to flat fees
[15:09] If the project is a success like many of believe it will be, I believe plenty of people will gladly done to a dev fund. I don't think the 500 should be burned.
[15:09] *donate
[15:09] centralized conservatorship, directed by community voting process

[15:10] <@wolfsokta> Thanks Under, that's an interesting idea that we should continue to discuss in the community. You also mentioned the existing website.
[15:10] It would need to be something where everyone with a QT has a vote
[15:10] think his computer went to sleep again :-/
[15:10] I agree UJP
[15:10] with the website
[15:10] No that’s ico jargon — any development fund tied to code would have to be centralized and would therefor fail
[15:11] ^
[15:11] ^
[15:11] ^
[15:11] dashes model for funding seems to be pretty decentralized
[15:11] community voting etc
[15:11] Once you have a dev fund tied to code then who gets to run it? Who mediates disputes?
[15:11] oh well another discussion
[15:11] Dash has a CEO
[15:12] <@wolfsokta> Yeah, let's keep discussing in the community spaces.
[15:12] Dash does have a good model. It's in my top ten.
[15:12] having the burn go to a dev fund is absolute garbage
[15:12] These dev chats should be more target than broad general discussions — changing the entire nature of the coin and it’s economics is best discussed in the RIPs or other means
[15:13] <@wolfsokta> Yup, let's move on.
[15:13] just becuase existing implementation are garbage doesnt mean that all possible future governance options are garbage
[15:13] <@wolfsokta> To discussing the website scenario mentioned by under.
[15:13] the website needs work. would be best if it could be migrated to github as well.
[15:13] What about this: Anyone can issue a vote once the voting feature has been added, for a cost. The vote would be what the coins could be used for.
[15:14] features for the site that need work are more user friendly links to binaries
[15:14] <@wolfsokta> We investigated how bitcoin has their website in Github to make it easy for contributors to jump in.
[15:14] that means active maintenance of the site instead of its current static nature
[15:15] <@wolfsokta> I really like how it's static html, which makes it super simple to host/make changes.
[15:15] the static nature isn’t due to interface it’s due to no contributors
[15:15] no contribution mechanism has been offered
[15:15] github hosted would allow that
[15:16] We used to run the Bitcoin website from the foundation & the GitHub integration seemed to cause some issues
[15:16] its doesnt necessarily have to be hosted by github but the page source should be on github and contributions could easily be managed and tracked
[15:17] for example when a new release is dropped, the ability for the downlaods section to have platform specific easy links to the general installers is far better for general adoption than pointing users to github releases
[15:18] <@wolfsokta> How do people currently contribute to the existing website?
[15:18] they dont?
[15:18] We did that and it was a complete pain to host and keep working — if someone wants to volunteer to do that work hey can surely make the website better and continually updated — but they could do that in Wordpress also
[15:19] I’d say keep an eye out for volunteers and maybe we can get a group together who can improve the site
[15:19] == digitalvap0r-xmr [[email protected]/web/cgi-irc/kiwiirc.com/ip.67.255.25.134] has joined #ravencoin-dev
[15:19] And they can decide best method
[15:20] I host the source for the explorer on github and anyone can spin it up instantly on a basic aws node. changes can be made to interface etc, and allow for multilingual translations which have been offered by some community members
[15:20] there are models that work. just saying it should be looked at
[15:20] i gotta run thank you all for your contributions
[15:20] <@wolfsokta> I feel we should explore the source for the website being hosted in GitHub and discuss in our next dev meeting.
[15:21] <@Chatturga> Thanks Under!

[15:21] <@wolfsokta> Thanks, we also need to drop soon.
[15:21] There is no official site so why care. Someone will do better than the next if RVN is worth it anyway. That's already the case.
[15:21] <@wolfsokta> Let's do 10 mins of open Q&A
[15:22] <@wolfsokta> Go...
[15:23] <@Chatturga> Beuller?
[15:24] No questions ... just a comment that the devs and community are great and I'm happy to be a part of it
[15:24] I think everyone moved to discord. I'll throw this out there. How confident is the dev team that things will be ready for oct 31st?
[15:24] <@wolfsokta> Alright! Thanks everybody for joining us today. Let's plan to get back together as a dev group in a couple of weeks.
[15:25] thanks block!
[15:25] <@wolfsokta> Urgo, very confident
[15:25] Please exclude trolls from discord who havent read the whitepaper
[15:25] great :)
[15:25] "things" will be ready..
[15:25] Next time on discord right?
[15:25] woah why discord?
[15:25] some of the suggestions here are horrid
[15:25] this is better less point
[15:25] == blondfrogs [[email protected]/web/freenode/ip.185.245.87.219] has quit [Quit: Page closed]
[15:25] Assets are working well on testnet. Plan is to get as much as we can safely test by Sept 30 -- this includes dev contributions. Oct will be heavy testing and making sure it is safe.
[15:26] people
[15:26] <@wolfsokta> Planning on same time, same IRC channel.
[15:26] == BW_ [[email protected]/web/freenode/ip.138.68.243.202] has quit [Quit: Page closed]
[15:26] @xmr any in particular?

My concerns about SmartCash

Hello folks!
I have been doing a lot of reading about the SmartCash cryptocurrency recently. SmartCash claims to be a private cryptocurrency that also focuses on a community-centered model.
However, a lot of what I've found has concerned me.
But first - I'd like to invite anyone with an opposing point of view to share their opinions after reading this. I'm not in this to spread baseless accusations, I just want an educated conversation. Please do not downvote simply because you disagree; instead, read my post, make a comment and discuss the topic with me. I've sent PM's to several people who support SmartCash in order to let them make their opinions clear.
That said, let's go through this point by point - we'll start with the distribution.
From the official SmartCash website:
Traditional cryptocurrencies, like Bitcoin, reward only the miners while neglecting the other actors that play an active role in maintaining, developing and promoting the project. SmartCash is a community-centric cryptocurrency, where community and development comes first. 80% of the block reward has been allocated to fund SmartHive community proposals as well as the Hive Teams. 20% of the remaining block reward has been allocated to Mining (5%) and SmartRewards (15%).
In the name of staying unbiased, I am going to acknowledge my ideological beliefs about mining, as well as my own personal biases as a miner, that miners should receive 100% of the rewards for the work they did. With this out of the way, let's discuss the mathematics of SmartCash's block reward distribution.
80% goes to community projects, 15% goes to SmartRewards (staking equivalent, but not used for consensus), and 5% goes to the miners. In theory, this will lead to 95% less miners than normal, ensuring miners get paid roughly the same. In practice, this won't necessarily be true.
But the existence of fewer miners also presents many issues. There have been several 51% attacks against cryptocurrencies that give all block rewards to miners - Krypton in 2016, Feathercoin in 2013, and Dashcoin (a cryptonote fork DSH, not DASH) by MinerGate in April of 2017.
Chain consensus with SmartCash is determined entirely by proof of work, not proof of stake; therefore you do not need to own any coins in order to attack the network and achieve 51% hashrate.
In the case of a cryptocurrency that gives miners 5% of the block rewards, achieving 51% of nethash is quite easy, because fewer people will be mining. SmartCash's current network hashrate is 10 Th/s or 10 trillion hashes per second; a conservative estimate for a GTX 1080's hashrate is 1 Gh/s or 1 billion hashes per second. Therefore, the network is currently secured by the equivalent of 10,000 GTX 1080 GPUs.
Given that this GPU costs approximately $500, it would take about $5 million to conduct a 51% attack on the network. At nicehash prices of ~0.3 BTC/TH/S/Day, this would cost ~$60,000 per day, taking into account a necessary raise in the offered price to 'persuade' more people to switch to Keccak algo, as only 2TH/s is currently for sale on Nicehash.
Even worse, Keccak (Smartcash’s hashing algorithm) was specifically designed to be ASIC-friendly. From the official Keccak website:
Keccak, the winner of the SHA-3 competition, is blazing fast when implemented on dedicated (ASIC) or programmable (FPGA) hardware.
So if somebody ever modified a Keccak ASIC for mining, it would also be easy to conduct a 51% attack.
Let’s move on. Remember how they said that 80% of the block rewards go to a community fund? That address is here, and it controls 55% of the SmartCash in existence. This address is used to fund proposals that are voted on by the community. The problem is that the private key to this address is owned by the developers - and regardless of their past honesty, this system still requires trust in them. A trust-required system is directly contrary to the principles of cryptocurrency. The developers, despite your trust in them, could still sell some of those coins at any time.
Next up we'll discuss SmartCash's privacy. SmartCash uses the Zerocoin protocol for privacy, as it was forked from Zcoin. Zerocoin breaks the link between sender and receiver, but unlike Zerocash and ringCT, it does not hide the transaction amount. Furthermore, SmartCash's privacy is optional, and it is transparent by default. Transparency by default is bad for the following reasons:
(1) it reduces the anonymity set
(2) it makes private transactions inherently more suspicious
(3) it allows sender to harm the privacy of recipient
(4) it makes it impossible to hide your wealth
(5) it makes the currency non-fungible.
My last concern with SmartCash is the coin distribution. Currently, as shown on the SmartCash Rich List, the top 100 addresses control 98.42% of funds. This is a highly unbalanced situation, and it also means that the vast majority of SmartCash wealth is held by a small number of people. With Bitcoin, the top 100 addresses control roughly 32% of funds, which is not perfect, but certainly much better.
In summary, SmartCash is a great idea - a private, community-oriented cryptocurrency - but it is executed in a suboptimal manner.
I would be happy to hear your opinions on this, whether you agree or disagree.
