Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Why Bitcoin is Superior to Gold

There is a constant war being fought between goldbugs, like Peter Schiff, and Bitcoin enthusiasts so I decided to make an outline, with links, comparing and contrasting gold and Bitcoin. I made this in November of 2019 (thus the information therein is based on figures from that time) but, being scatter brained, neglected to post this for the Bitcoin community to see. The yardsticks I used to compare the two assets included the following: shipping/transactions costs, storage costs, censorship factor, settlement time, stock to flow, blockchain vs clearing house, validation, etc. I will also touch on Roosevelt's gold confiscation executive order in 1933, transporting gold during the Spanish Civil War in 1936, and the hypothetical cost for Venezuela to repatriate its gold more recently.
I will provide a brief summary first then follow that with the outline I made. This information can be used as a tool for the Bitcoin community to combat some of the silly rhetoric coming from goldbugs such as Peter Schiff and James Rickards. I would like to make it clear, however, that I am not against gold and think that it performed its role as money very well in a technologically inferior era, namely Victorian times but I think Bitcoin performs the functions of money better than gold does in the current environment.
I have been looking to make a contribution to the Bitcoin community and I hope this is a useful and educational tool for everyone who reads this.
Summary:
Shipping/transaction costs: 100 ounces of gold could be shipped for 315 dollars; the comparable dollar value in Bitcoin could be sent for 35 dollars using a non-segwit address. Using historical precendent, it would cost an estimated $32,997,989 to transport $1 billion in gold using the 3.3% fee that the Soviets charged the Spaniards in 1936; a $1 billion Bitcoin transaction moved for $690 last year by comparison. Please note that the only historic example we can provide for moving enormous sums of gold was when the government of Spain transported gold to Moscow during the Spanish Civil War in 1936. More information on this topic will be found in the notes section.
Storage costs: 100 ounces of gold would require $451 per year to custody while the equivalent value of Bitcoin in dollar terms could be stored for the cost of a Ledger Nano S, $59.99. $1 billion USD value of gold would cost $2,900,000 per year while an Armory set up that is more secure would run you the cost of a laptop, $200-300.
Censorship factor: Gold must pass through a 3rd party whenever it is shipped, whether for a transaction or for personal transportation. Gold will typically have to be declared and a customs duty may be imposed when crossing international borders. The key take-away is gatekeepers (customs) can halt movement of gold thus making transactions difficult. $46,000 of gold was seized in India despite the smugglers hiding it in their rectums.
Settlement time: Shipping gold based on 100 ounces takes anywhere from 3-10 days while Bitcoin transactions clear in roughly 10 minutes depending on network congestion and fee size.
Historic confiscation: Franklin Roosevelt confiscated and debased the paper value of gold in 1933 with Executive Order 6102. Since gold is physical in nature and value dense, it is often stored in custodial vaults like banks and so forth which act as a honeypot for rapacious governments.
Stock to flow: Plan B's stock to flow model has become a favorite on twitter. Stock to flow measures the relationship between the total stock of an asset against the amount that is produced in a given year. Currently gold still has the highest value at 62 while Bitcoin sits at 50 in 2nd place. Bitcoin will overtake gold in 2024 after the next halving.
Blockchain vs clearing house: gold payments historically passed through a 3rd party (clearinghouse) in order to be validated while Bitcoin transactions can be self validated through the use of a node.
Key Takeaway from above- Bitcoin is vastly superior to gold in terms of cost, speed, and censorship resistance. One could theoretically carry around an enormous sum of Bitcoin on a cold card while the equivalent dollar value of gold would require a wheelbarrow...and create an enormous target on the back of the transporter. With the exception of the stock to flow ratio (which will flip in Bitcoin's favor soon), Bitcoin is superior to gold by all metrics covered.

Breaking down Venezuela conundrum; http://blogs.reuters.com/felix-salmon/2011/08/23/how-to-get-12-billion-of-gold-to-venezuela/
“The last (and only) known case of this kind of quantity of gold being transported across state lines took place almost exactly 75 years ago, in 1936, when the government of Spain removed 560 tons of gold from Madrid to Moscow as the armies of Francisco Franco approached. Most of the gold was exchanged for Russian weaponry, with the Soviet Union keeping 2.1% of the funds in the form of commissions and brokerage, and an additional 1.2% in the form of transport, deposit, melting, and refining expenses.”
“Venezuela would need to transport the gold in several trips, traders said, since the high value of gold means it would be impossible to insure a single aircraft carrying 211 tonnes. It could take about 40 shipments to move the gold back to Caracas, traders estimated. “It’s going to be quite a task. Logistically, I’m not sure if the central bank realises the magnitude of the task ahead of them,” said one senior gold banker.”
“So maybe Chávez intends to take matters into his own hands, and just sail the booty back to Venezuela on one of his own naval ships. Again, the theft risk is obvious — seamen can be greedy too — and this time there would be no insurance. Chávez is pretty crazy, but I don’t think he’d risk $12 billion that way.”
“Which leaves one final alternative. Gold is fungible, and people are actually willing to pay a premium to buy gold which is sitting in the Bank of England’s ultra-secure vaults. So why bother transporting that gold at all? Venezuela could enter into an intercontinental repo transaction, where it sells its gold in the Bank of England to some counterparty, and then promises to buy it all back at a modest discount, on condition that it’s physically delivered to the Venezuelan central bank in Caracas. It would then be up to the counterparty to work out how to get 211 tons of gold to Caracas by a certain date. That gold could be sourced anywhere in the world, and transported in any conceivable manner — being much less predictable and transparent, those shipments would also be much harder to hijack. How much of a discount would a counterparty require to enter into this kind of transaction? Much more than 3.3%, is my guess. And again, it’s not entirely clear who would even be willing to entertain the idea. Glencore, perhaps?”
“But here’s one last idea: why doesn’t Chávez crowdsource the problem? He could simply open a gold window at the Banco Central de Venezuela, where anybody at all could deliver standard gold bars. In return, the central bank would transfer to that person an equal number of gold bars in the custody of the Bank of England, plus a modest bounty of say 2% — that’s over $15,000 per 400-ounce bar, at current rates. It would take a little while, but eventually the gold would start trickling in: if you’re willing to pay a constant premium of 2% over the market price for a good, you can be sure that the good in question will ultimately find its way to your door. And the 2% cost of acquiring all that gold would surely be much lower than the cost of insuring and shipping it from England. It would be an elegant market-based solution to an artificial and ideologically-driven problem; I daresay Chávez might even chuckle at the irony of it. He’d just need to watch out for a rise in Andean banditry, as thieves tried to steal the bars on their disparate journeys into Venezuela.”

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Bitcoin Futures, Options, and Open Interest: Crypto Derivatives Break Records After the Halving

##https://news.bitcoin.com/wp-content/uploads/2020/05/gg77.jpg
https://news.bitcoin.com/wp-content/uploads/2020/05/728x90-5-5ea7e35d31890.jpg
Since the market rout on March 12, otherwise known as ‘Black Thursday,’ bitcoin futures and options contracts have seen significant demand. On May 14, CME Group saw the total number of outstanding derivatives contracts (open interest) touch a high of $142 million. Four days later, CME broke records again. Data from the researchers at Skew.com detailed that CME’s regulated bitcoin options open interest is up 10x this month.
##Deribit’s Massive Options Volumes and CME Group’s Regulated Bitcoin Derivatives Markets Touch New Highs ##
Ever since the halving on May 11, there’s been a lot of action when it comes to bitcoin-based derivatives products. The research and analysis team from Skew.com publishes daily information about CME’s bitcoin futures and options, products from Bakkt, and a slew of other exchanges that offer crypto derivatives.
For instance, Skew detailed that the exchange Deribit’s bitcoin options open interest had touched $1 billion for the first time this week. On May 14, CME Group saw $142 million in 10-day combined daily volumes, which is far smaller than Deribit’s volumes but still a milestone for CME. The regulated exchange touched $172 million in total CME BTC options open interest, following the record performance four days prior.
https://news.bitcoin.com/wp-content/uploads/2020/05/image-2020-05-21-112250.jpg
On May 8, CME Group published a blog post about the bitcoin halving and discussed its derivatives products as well. “The emergence of a futures and options market has created a new ecosystem for bitcoin markets, which faces its first supply cut since 2016,” CME Group’s Payal Lakhani wrote at the time.The May 14, open interest breakout for CME Group’s bitcoin options was the first time it has ever crossed $100 million, Skew noted.
Deribit open interest only.
Between Deribit, CME, Bakkt, Okex, and Ledgerx the volumes pushed “total bitcoin options open interest to a new record [of] $1.1 billion,” Skew explained. Additionally, “CME bitcoin futures traded nearly $1 billion,” on May 12, 2020 the researchers disclosed.
##Bitcoin Halving Fuels Speculation, the Very Driver of Crypto Derivatives Markets ##
Even Bakkt’s trade volumes increased after the halving, despite lackluster trading volume months prior to the event. “Bakkt had a solid halving session with a record volume day in $ notional, $51.8 million bitcoin futures crossed,” Skew tweeted the day after bitcoin’s third halving.
Total BTC options open interest between five exchanges.
There’s been a lot of action with ethereum-based (ETH) derivatives products as well. Skew explained on May 21 that “17,500+ Jun20 240 calls traded yesterday on Deribit [at] $10.1 average dollar equivalent price.” When looking at Deribit’s ETH options buy/sell ration Skew said it “reads like overwriting as 76% of liquidity takers were sellers yesterday.”
https://news.bitcoin.com/wp-content/uploads/2020/05/4b0a23dc855c807a633fc5c44ef92ab9.png
The market carnage in mid-March was devastating to a lot of traders, and many derivatives players lost their shirts during massive liquidations. The price of BTC has strengthened since it dropped to $3,600 per coin on March 12, and cryptocurrency derivatives markets have seen a great deal of increased action since then as well. Moreover, the third bitcoin halving that took place on May 11, 2020, at 2:30 p.m. ET, sparked even more interest in bitcoin-based futures and options contracts betting on the next few months.
What do you think about the latest interest increase in bitcoin derivatives products? Let us know in the comments below.

(self.Bitcoin) by /u/Kinolva removed from /r/Bitcoin within 135-145min

'''
Let me remind all you old-timers, and inform the newbies showing up here because of the halving: There will only be a maximum of 21 million bitcoins. Ever. Approximately 4 million have been permanently [LOST]1 , bringing the maximum circulating total to 17 million. This total number won't be reached until 2140 due to Bitcoin's [issuance schedule]2 . This is "quantitative hardening."
Total number of millionaires (in USD value) worldwide is around 33 million ([source]3 ).
The factual math is simple: there is not enough Bitcoin in the world for even HALF of today's millionaires to own just ONE SINGLE BITCOIN. Much less all the future millionaires that will be born as the human population approaches [10bn]4 .
Bitcoin is SCARCE. Check out the [S2F model]5 for a good explanation of why scarcity and value correlate. Recently updated to the [S2FX model]6 for a model that incorporates more data, and is more accurate.
Furthermore: If you are able to acquire even one BTC today: Enjoy the feeling. You are an early adopter. And one of a very select number of humans. Owning just ONE BTC means that you are--at minimum--in the top 0.2% ([17M / 8Bn * 100]7 *100&ie=UTF-8&oe=UTF-8)) of the human population in terms of total possible bitcoin wealth distribution. The percentage is much lower than that, of course, given that there are lots of whales out there with 1000+ BTC each.
Edit: And never-mind the idiots that will say something asinine like "my pubic hairs are limited in number too...does that make them valuable?" Your pubic hairs have zero network utility, whereas every day Bitcoin proves it has extraordinary utility as (perhaps) the most perfect form of money humans have yet created.
Stack those sats!
That is all.

EDIT: Happy Halving!

هاوینگ بیت کوین

هاوینگ بیت کوین

هاوینگ بیت کوین

هاوینگ بیت کوین ۲۳ اردیبهشت اتفاق خواهد افتاد. اما هاونیگ بیت کوین چیست؟ تاثیر هایونگ بر قیمت بیت کوین چه خواهد بود؟ چه معنایی برای استخراج‌کنندگان و چشم‌انداز بلند مدت ارزهای دیجیتال خواهد داشت؟ برای پاسخ به این سوالات با ما همراه باشید.

این مطلب در یک نگاه …

۰. سه نظریه درباره تاثیر هاوینگ بر قیمت بیت کوین ۰. شرخی کوتاه از هاوینگ بیت کوین
مفصل‌تر بخوانید … ۱. مقدمه ۲. هاوینگ بیت کوین چیست ؟ ۳. چه کسی زمان‌بندی توزیع بیت کوین را تعیین کرده است؟ چرا؟ ۴. تأثیر هاوینگ بر قیمت بیت کوین چگونه است؟ ۵. چرا استخراج کنندگان پاداش دریافت می‌کنند؟ ۶. چه اتفاقی می‌افتد اگر پاداش بلاک‌ها کم شود؟ ۷. جمع‌بندی

۰. سه نظریه درباره تاثیر هاوینگ بر قیمت بیت کوین

یک

برخی اعتقاد دارند که با کاهش نرخ بیت کوین‌هایی که ماینرها می‌توانند به سیستم تزریق کنند، و با فرض ثابت ماند تقاضا، ارزش بیت کوین بیشتر می‌شود. این تئوری به این شکل است که زمانی که عرضه بیت کوین کاهش می‌یابد، تقاضا برای آن ثابت باقی می‌ماند و قیمت را بالا می‌برد. اگر این نظریه صحیح باشد، ما می‌توانیم افزایش قیمت را بعد از هاوینگ‌های بعدی، مشاهده کنیم.

دو

برخی دیگر استدلال می کنند که با توجه به قابل پیش‌بینی بودن این برنامه و آگاهی همه از آن، تاثیر هاوینگ بر قیمت بیت کوین پیش از اتفاق افتادن آن رخ می‌دهد. این تئوری می‌گوید که، معامله‌گران مدتهاست که می‌دانند پاداش بلوک بیت کوین کاهش خواهد یافت. این آگاهی به آنها زمان کافی را برای آماده‌سازی ‌می‌دهد. در نتیجه در نتیجه افراد بیت کوین می‌خرند و با افزایش تقاضا، و از طرفی دیگر حرکت گاوی قیمت بیت کوین قبل از هاوینگ بالا می‌رود.

سه

برخی دیگر کمی پیچیده‌تر فکر می‌کنند. آن‌ها می‌گویند که با آگاهی افراد از این اتفاق قابل پیش‌بنی، تقاضا برای بیت کوین بالا می‌رود و سرمایه‌گذران زمان کافی برای آماده‌سازی خواهند داشت. در نتیجه تاثیر هاوینگ بر قیمت بیت کوین (بخاطر این قابل پیش‌بینی بودن) قبل از رخ دادن اتقاف میافتد. برخی از این پدیده با نام پیشخور شدن یاد می‌کند.
حال این افراد می‌گویند که اگر قرار بود هاوینگ بر قیمت تاثیر داشته باشد، باید تا الان تاثیر خود را می‌گذاشت. در حالی که چنین تاثیری مشاهده نشده است. بنابراین اگر تا کنون تاثیری نداشته است، پس از این به بعد، و با رخ دادن آن در ۲۳ اردیبهشت هم اتفاقی نخواهد افتاد.
۰. اگر وقت ندارید این داستان را بخوانید …

۱

پول، دقیقا مثل همه‌ی کالاهای دیگر است. ارزش یک پول به مقدار عرضه آن، مقداری که از آن وجود دارد و میزان تقاضایش بستگی دارد. دولت‌ها هر زمانی که بخواهند می‌توانند پول چاپ کنند. معمولا بانک‌های مرکزی هر چند ماه یک بار جمع می‌شوند تا تصمیم بگیرند که عرضه پول را، با چاپ آن دوباره تنظیم بکنند یا نه. اما اگه شرایط اضطراری پیش آید، این تصمیم خیلی سریع‌تر گرفته می‌شود. درست مثل همان چیزی که با آمدن کرونا شاهدش بودیم. اما بیت کوین هیچ بانکی مرکزی‌ای یا هیئت مدیری‌ای یا جایی که بتواند کنترلش کند ندارد. پس چگونه بیت کوین تصمیم می‌گیرد که چه قدر بیت کوین چاپ کند؟ در طول فرایندی به اسم هاوینگ!

۲

در سال ۲۰۰۸ ساتوشی ناکاموتو خالق بیت کوین ایده‌ای در سر داشت. چه می‌شد اگر آدم‌ها را به طور کامل از شر دخالت دولت‌ها و مراکز بر روی پول خلاص می‌کردیم و مطابق با یک برنامه مشخص که بیشتر از ۱۰۰ سال طول میکشید پول خاصی را خلق می‌کردیم که توسط خود انسان‌ها کنترل می‌شد؟ این پول احتمالا خسته کننده، قابل پیش بینی و قابل اعتماد می‌بود. چرا که افراد می‌توانستند بر اساس آن برنامه‌ریزی‌های بلندمدتشان را با اعتماد و بدون نگرانی درباره اتفاق‌های ناگهانی یا غیرقابل پیش بینی انجام دهند. اما برای آکه بیت کوین ارزشمند بماند، باید نایاب باشد، دقیقا مثل طلا. ناکاموتو حداکثر تعداد بیت کوین‌ها ممکن رو ۲۱ میلیون تعیین کرد. بنابراین عرضه بیت کوین محدود است و به لطف هاوینگ نرخ عرضه غیرقابل تغییر و قابل پیش‌بینی دارد. اما هاوینگ چگونه کار میکند؟

۳

بیایید اول فرایند استخراج را مرور کنیم. اینگونه فکر کنید که استخراج یه قرعه کشی است که هر ۱۰ دقیقه یک برنده دارد. و ماینرها برای وارد شدن به این قرعه کشی، یک مساله ریاضی را حل میکنند و یک بلیت قرعه کشی به دست میاورند. در اوایل، کامپیوترها برای ایجاد این بلیت‌ها طراحی نشده بودند. بنابراین هر ماینر تعداد بلیت زیادی را نمیتونست برای هر قرعه کشی ایجاد کند. در نیتجه هر کسی می‌توانست با کامپیوترش بلیت به دست آورد و برای شرکت در این قرعه کشی و برنده شدن شانس داشته باشه. در واقع مثلا اگر شما ۳ بلیت به دست میاوردید، برای برنده شدن در قرعه کشی ۳ شانس داشتید. اما الان تو سال ۲۰۲۰ ماشین‌های خاصی برای استخراج وجود دارند و شرکت‌ها انبارهای بزرگی را با این ماشین‌ها پر میکنند. این انبارها در جاهایی از جهان هستند که برق ارزان هستند.

۴

هر ۱۰ دقیقه یک ماینر خوش شانس در این قرعه کشی برنده میشود. و به عنوان پاداش به او بیت کوین داده میشود. در سالاهای اول زمانی که بیت کوین ارزشی نداشت این پاداش ۵۰ بیت کوین در هر ۱۰ دقیقه بود. که به پول الان چیزی حدود ۲۵۰ هزار دلار می‌شد! اما در آن زمان ارزشش حتی کمتر از ۵۰ سنت بوده است! با گذشت زمان و با رخ دادن هاوینگ در هر چهار سال، مقدار این پاداش هم کم شده است. در اولین هاوینگ در سال ۲۰۱۲ پاداش از ۵۰ به ۲۵ رسید و قیمت از ۲ دلار به ۲۷۰ دلار افزایش یافت. در سال ۲۰۱۶ قیمت به ۷۰۰ دلار رسید و تا حباب های سال ۲۰۱۷ و ۲۰۱۸ به رشدش ادامه داد. تو هاونیگ بعدی پاداش به ۶.۲۵ می‌رسد اما معلوم نیست اتفاقی مشابه برای قیمت بیافتد یا نه. هاونیگ تعداد ییت کوین‌هایی که می‌توان در قرعه کشی برنده شد را کاهش می‌دهد. اما همزمان تعداد بلیت‌هایی که در هر قرعه کشی می‌تواند شرکت کند هم بیشتر و بیشتره شده است. شرکت تو این قرعه کشی برای ماینر‌ها از نظر مالی صرفه دارد. چرا که در کنار کاهش پاداش‌ها، ارزش بیت کوین هم بالا رفته است.

۵

بنابراین هاوینگ یک فرایند کند، بلند مدت و قابل پیش بینی برای کاهش نرخ تعداد بیت کوین های جدیدی است که به وجود می‌آیند. این فرایند تا جایی که دیگه استخارج بیت کوین‌های جدید هیج معنایی نداشته باشه ادامه دارد. در طول سال‌ها رقابت بین ماینرها بیشتر و بیشتر شده. و حتی ماینرهایی که به دنبال درامد روزانه هستند هم جذب شده‌اند. همه‌ی این‌ها امنیت شبکه بیت کوین رو بیشتر میکند. هیچ کس نمی‌تواند بگوید که تاثیر هاوینگ بر قیمت چه خواهد بود و قیمت بعد از هاوینگ بعدی چه قدر بالا می‌رود. برخی انتظار اتفاق‌های بزرگی را دارند. شاید ۶ رقمی شدن بیت کوین! در حالی که دیگران فکر می‌کنند که چون این بار همه از هاونیگ خبر دارند، پس تاثیرش از قبل بر روی قیمت آمده است.

۶

یکی از سوال‌هایی که باقی می‌ماند این است که آیا با کم شدن پاداش‌ها، همچنان استخراج برای ماینرها جذاب می‌ماند؟ یادتان باشد که اگه ماینرها سود نکنند، دیگر استخراج نخواهند کرد. به هر حال آن‌ها محض رضای خدا هزینه‌ای برای برق و ماشین‌ها پرداخت نمی‌کنند. پس اگه قیمت بیت کوین بالا نرود، احتمالا ماینرها هزینه انتقال بیشتری را از کاربران طلب خواهند کرد. که باعث میشود سیستم بیت کوین برای انتقال ارزش گران و پرهزینه باشد.
هاونیگ به طور منظم مثل یک ساعت اتفاق می‌افتد و فارغ از نتیجه نهایی، مکانیزمی جذاب برای جلو بردن سیستم بیت کوین و به طور قطع از خلاقانه‌ترین تجربه‌ها در جهان بلاک چین است.
هاوینگ بیت کوین چیست | زمان هاوینگ بیت کوین | تاثیر هاوینگ بر قیمت بیت کوین

مفصل‌تر بخوانید …

۱. مقدمه

شاید در نگاه اول،فکر کنید هاوینگ، اسم یک فیلم ترسناک درباره قتل‌های زنجیره‌ای باشد. در حالی که هاوینگ، نام یکی از جذاب‌ترین اتفاقات در طول تاریخ بیت کوین است. «هاوینگ» معادل لغت «Halving» است. Halving در انگلیسی به معنای نصف شدن است. برای مثال جمله‌ی «the halving of oil price» به معنای نصف شدن قیمت نفت است. خیلی خلاصه منظور از هاوینگ بیت کوین، نصف شدن پاداش هر بلاک است.
در ماه می (حدود ۲۳ اردیبهشت)، تعداد بیت‌کوین‌هایی (BTC) که در هر ۱۰ دقیقه وارد گردش می‌شوند (همان پاداش بلاک) به نصف کاهش می‌یابد و از ۱۲.۵ بیت‌کنوین به ۶.۲۵ بیت‌کوین می‌رسد. این اتفاق به راحتی قابل دیدن و پیش‌بنی است. چرا که هر چهار سال یک بار اتفاق می‌افتد و قبلا هم دو بار اتفاق افتاده است.
طمع رسیدن به ثروت، چیزی است که توجه‌ها را به این اتفاق جلب می‌کند. مقدار بیت‌کوین‌هایی که به سیستم تزریق می‌شود، به ناگهان کاهش پیدا می‌کند. در حالی که بر روی کاغد، تقاضا ثابت خواهد ماند. در نتیجه این اتفاق (و با توجه به نمودار عرضه و تقاضا در اقتصاد) احتمالا قیمت بیت کوین بالا خواهد رفت. به این ترتیب، این رویداد بحث‌های زیادی را درباره پیش بینی قیمت بیت کوین و نحوه پاسخگویی بازار به آن راه انداخته است.
📷نمودار تقاضا و عرضه بیت کوین‌های جدید وارد شده به سیستم (در هر ده دقیقه) پس از رخ دادن هالوینگ
چند نکته: ۱. این نمودار نمودار اصلی عرضه و تقاضای بیت کوین نیست. چرا که حتی با کاهش نرخ تعداد بیت‌کوین‌هایی که به سیستم وارد می‌شود، باز هم میزان عرضه بیت‌کوین افزایش خواهد یافت. عرضه در این نمودار، مربوط به بیت‌کوین‌های جدید است. ۲. معلوم نیست که چه اتفاقی برای تقاضا خواهد افتاد. اما اگر فرض کنیم تقاضا ثابت است، بر روی کاغذ قیمت این بیت‌کوین‌های جدید باید بالا رود. ۳. با بالا رفتن قیمت بیت‌کوین‌های جدید، قیمت کل بیت‌کوین‌های در بازار نیز تحت تاثیر قرار می‌گیرد.
مایکل دوبروسکی (Michael Dubrovsky)، بنیانگذار بخش تحقیق و توسعه در PoWx می‌گوید:
زمانی که استخراج‌کنندگان، بیت‌کوین‌های کمتری برای فروش داشته باشند، در نتیجه بیت‌کوین‌های کمتری برای خرید در دسترس خواهد بود.
اما کاهش دوره‌ای نرخ استخراج بیت کوین، نسبت به هرگونه حرکت کوتاه مدت دیگری ذر قیمت می‌تواند برای عملکرد بیت کوین اهمیت داشته باشد. پاداش بلوک یکی از مولفه های مهم بیت کوین است. چیزی که امنیت سیستم بیت کوین را تضمین می‌کند. با توجه به اینکه در دهه‌های آینده، این پاداش‌ها به صفر می‌رسند، می‌توانند انگیزه‌های اقتصادی برای استخراج بیت کوین را از بین ببرند. چیزی که در نهایت امنیت شبکه بیت کوین را تحیت تاثیر قرار می‌دهد.

۲. هاوینگ بیت کوین چیست ؟

بیت کوین‌های جدیدی که به عنوان پاداش بلاک، به چرخه بیت‌کوین‌ها وارد می‌شوند، توسط استخراج کنندگان یا ماینرها تولید می‌شود. این استخراج کنندگان از تجهیزات الکترونیکی گران‌قیمتی برای به دست آوردن یا استخراج استفاده می‌کنند. در هر ۲۱۰،۰۰۰ بلاک، یا تقریبا در هر چهار سال، تعداد کل بیت کوین که استخراج کنندگان به طور بالقوه می‌توانند برنده شوند، نصف می‌شود.
📷عرضه بیت کوین و پاداش های بلاکی
در سال ۲۰۰۹، این سیستم با ۵۰ سکه بیت کوین برای پاداش هر بلاک در هر ۱۰ دقیقه شروع به کار کرد. در حال حاضر با گذشت ۲ هاوینگ، این پاداش به ۱۲.۵ بیت کوین رسیده است. این فرایند درزمانی که کل ۲۱ میلیون بیت کوین (احتمالا در سال ۲۱۴۰) استحراج شود به پایان خواهد رسید.

۳. چه کسی زمان‌بندی توزیع بیت کوین را تعیین کرده است؟ چرا؟

ساتوشی ناکاموتو (Satoshi Nakamoto)! خالق بیت کوین، که البته شاید تنها یک نام مستعار از یک فرد یا یک گروه باشد. او تقریبا یک سال پس از انتشار این نرم افزار به جهان ناپدید شد. بنابراین او، یا آنها (ما از این بعد با «آن‌ها» به او اشاره می‌کنیم) دیگر نیستند تا توضیح دهند که چرا این فرمول خاص را برای افزودن بیت کوین‌های جدید به سیستم انتخاب کردند. (و چرا اصلا تعداد آن‌ها را به ۲۱ میلیون محدود کرده‌اند، چرا مثال عدد ۱۰۰ میلیون را انتخاب نکردند؟!)
اما ایمیل‌های الکترونیکی اولیه که توسط ناکاموتو نوشته است، تا حدی این موضوع را روشن می‌کند. اندکی پس از انتشار مقاله بیت کوین، ناکاموتو به طور خلاصه درباره روش‌های مختلفی که سیاست پولی منتخب آنها (برنامه‌ی زمانی که استخراج کنندگان مطابق با آن پاداش خود را دریافت می‌کنند) عمل خواهد کرد و در مورد شرایطی که این امر می‌تواند منجر به رکود (زمانی که قدرت خرید ارز افزایش پیدا می‌کند) یا تورم (زمانی که قیمت کالاها یا خدماتی که می‌توان با یک ارز خرید کرد افزایش پیدا می‌کند) شود توضیح داد.
در آن زمان، ناکاموتو نمی‌توانست حدس بزند که چند نفر از این پول آنلاین جدید استفاده خواهد کرد. آنها درباره اینکه چرا این فرمول خاص را انتخاب کردند، خیلی کم توضیح دادند: «سکه‌ها به هر حال باید از ابتدا توزیع شوند و به نظر می رسد یک نرخ ثابت بهترین فرمول است.» جمله اصلی ناکاموتو به شکل زیر است.
«Coins have to get initially distributed somehow, and a constant rate seems like the best formula.»
در اکثر ارزهای منتشر شده، یک بانک مرکزی دارای ابزارهایی است که به آن امکان افزودن یا حذف آن ارز از سیستم را می دهد. مثلا بانک مرکزی آمریکا، می‌تواند دلار چاپ کند یا دلارها را از بازار جمع کند. به عنوان مثال اگر اقتصاد در وضع بدی باشد، دولت می‌تواند گردش مالی را افزایش داده و با خرید اوراق بهادار از بانک‌ها به افراد وام‌ دهد. از طرف دیگر، اگر دولت بخواهد دلارها را از اقتصاد خارج کند، می تواند اوراق بهادار را خود را به افراد بفروشد.
در آن زمان، ناکاموتو نمی‌توانست حدس بزند که چند نفر از این پول آنلاین جدید استفاده خواهد کرد. (حتی نمی‌دانست که اصلا کسی استفاده خواهد کرد یا نه)
At the time, Nakamoto couldn’t have known how many people would use the new online money (if anyone).
چه خوب باشد چه بد، بیت کوین کمی با بقیه فرق دارد. مقدار عرضه‌ی این ارز و زمان آن دقیقا مطابق با یک برنامه زمان‌بندی مشخص تعیین شده. و این برنامه غیر قابل تغییر است.
بر خلاف سیاست پولی ارزهای صادر شده دولتی، که از طریق فرآیندهای سیاسی و نهادهای انسانی وضع می‌شود، سیاست پولی بیت کوین توسط کدی که در شبکه پخش می‌شود، تعیین می‌شود. اگر این کد بخواهد تغییر کند، نیاز به یک هماهنگی و توافق جمعی در بین کل جامعه و شبکه بیت کوین است.
بلاکچین دات کام (Blockchain.com) در یکی از مطالب خود که در وبلاگش پیش از هاوینگ سال ۲۰۱۶ منتشر شد می‌گوید: «بر خلاف اکثر ارزهای ملی که می‌شناسیم، مانند دلار یا یورو، بیت کوین با یک عرضه ثابت و برنامه زمان‌بندی قابل پیش‌بینی طراحی شده است. فقط ۲۱ میلیون بیت کوین وجود خواهد داشت. این تعداد از پیش تعیین شده باعث محدود شدن آن می‌شود. این محدودیت و کمیابی بیت کوین (مانند طلا) در کنار کاربرد آن است که باعث حفظ ارزش آن در بازار می‌شود.»
یکی دیگر از جنبه های منحصر به فرد بیت کوین، برنامه ناکاموتو برای پاداش بلاک‌ها است. پاداش بلاک‌ها در طول زمان کاهش پیدا می‌کند. این موضوع یکی دیگر از تفاوت‌های بیت کوین با سیستم های مالی مدرن است. سیستم‌هایی که در آن بانک های مرکزی عرضه پول را کنترل می‌کنند. برخلاف بیت کوین، عرضه دلار از سال ۲۰۰۰ تا کنون حدودا سه برابر شده است.

ناکاموتو سرنخ‌هایی را از این که بیت کوین را به دلایل سیاسی به وجود آورده جای گذاشته است.

اولین بلاک بلاکچین بیتکوین Genesis block است. این بلاک که ده ساله شده در ۳ ژانویه ۲۰۰۹ توسط ساتوشی استخراج شد. نکته جالب پیام مخفی­ است که ساتوشی در آن قرار داده. یکی از پارامتر‌هایی که در هر بلاکی ذخیره می‌شود کوین­ بیس (Coinbase) نام دارد. کوی­ن‌بیس پارامتری است که میزان پاداش ماینرها به ازای ساخت یک بلاک را معین می‌کند. اما در اولین بلاک یا همان بلاک جنسیس، می­‌توان هر متغییری را در آن جای داد. نکته جالب این است که ناکاموتو رشته­ ی (string) زیر را در این بلاک جای داده است:
{۰۴FFFF001D0104455468652054696D65732030332F4A616E2F323030 39204368616E63656C6C6F72206F6E206272696E6B206F66207365636 F6E64206261696C6F757420666F722062616E6B73}
پس از رمزگشایی این رشته متن زیر به دست می‌آید.
{The Times 03/Jan/2009 Chancellor on brink of second bailout for banks}.
که معنای آن این است: «روزنامه The Times در تاریخ ۳ ژانویه ۲۰۰۹ رئیس خزانه‌داری [انگلستان] در آستانه‌ی اهدای کمک مالی به بانک‌ها است.». این پیام بی‌ثباتی­‌های اقتصادی که بخاطر استفاده­‌ی گسترده از سیستم بانکداری ذخیره کسری به وجود آمده است را سرزنش می‌کند. در سیستم ذخیره کسری، بانک می‌تواند پول افراد را به افراد یا شرکت­‌های دیگر وام دهد. در واقع، می‌تواند پول تولید کند!
بسیاری این پیام را به عنوان نشانه‌ای از عقاید و اهداف سیاسی ناکاموتو تفسیر می‌کنند. بیت کوین در صورت پذیرفته شدن توسط جوامع، می‌تواند قدرت پولی را که بانک‌ها و دولت‌ها بر سیاست‌های پولی دارند را کاهش دهد. هیچ نهاد مرکزی نمی‌تواند بیت کوین را خارج از برنامه دقیق آن ایجاد کند.

۴. تأثیر هاوینگ بر قیمت بیت کوین چگونه است؟

بسیاری از افراد فکر می‌کنندکه تاثیر هاوینگ بر قیمت بیت کوین مثبت است. تا جایی که آن را تا حد بسیار زیادی افزایش می‌دهد. برای همین موضوع نیز توجه خیلی‌ها به هاوینگ جلب شده است. اما حقیقت این است که، هیچ کس نمی‌داند چه اتفاقی خواهد افتاد. بیت کوین تاکنون دو بار هاوینگ را تجربه کرده است.
📷جدول زمان‌بندی هاوینگ‌های بیت کوین
هاوینگ سال ۲۰۱۲ برای اولین بار نشان داد که بازار چگونه به آن واکنش نشان خواهد داد. تا آن زمان، جامعه بیت کوین خیلی دقیق نمی‌دانست (یا همه‌ی آن‌ها نمی‌دانستند) که چگونه یک کاهش ناگهانی در پاداش می‌تواند روی شبکه تاثیر بگذارد. تنها اندکی پس از هاوینگ بود که دیدند با هاوینگ قیمت شروع به افزایش کرد.
دومین هاوینگ که در سال ۲۰۱۶ رخ داد، کاملا پیش‌بینی شده بود. درست مانند همین هاونیگی که در پیش است. مثال الان که برخی از سایت‌ها مانند coindesk.com یک روز شمار برای آن قرار دادند، در آن زمان نیز این روز شمار وجود داشت. همه به دنبال آن بودند تا ببیند هاوینگ چه تاثیری بر قیمت خواهد داشت.
در تاریخ ۱۶ ژوئیه ۲۰۱۶، روزی که هاونیگ دوم رخ داد، قیمت ۱۰ درصد کاهش یافت و به ۶۱۰ دلار رسید، اما سپس به همان جایی که قبلا بود بازگشت. شواهد اندکی وجود داشت که نشان می‌داد کاهش ناگهانی نرخ استخراج بیت کوین تاثیر طولانی مدتی بر قیمت داشته باشد. در آن زمان، جیکوب دونلیلی تا آنجا پیش رفت که این رویداد را «عذاب کسالت آور» خواند.

.

در حالی که تاثیر فوری بر قیمت بیت کوین اندک بود، بازار به تدریج نسبت به هاوینگ واکنش نشان داد و قیمیتش افزایش پیدا کرد. برخی معتقدند که این افزایش قیمت نتیجه با تاخیری از هاوینگ بوده است. این تئوری به این شکل است که زمانی که عرضه بیت کوین کاهش می‌یابد، تقاضا برای آن ثابت باقی می‌ماند و قیمت را بالا می‌برد. اگر این نظریه صحیح باشد، ما می‌توانیم افزایش قیمت‌های مشابه را بعد از هاوینگ‌های بعدی، از جمله هاوینگ امسال مشاهده کنیم.
برخی دیگر استدلال می کنند که با توجه به قابل پیش‌بینی بودن این برنامه و آگاهی همه از آن، این تغییر در نرخ استخراج پیش از آنکه اتفاق بیافتد بر قیمت تاثیر خواهد داشت. آن‌ها تنها معتقند که این تاثیر از قبل گذاشته می‌شود. این تئوری می‌گوید که، معامله‌گران مدتهاست که می‌دانند پاداش بلوک بیت کوین کاهش خواهد یافت. این آگاهی به آنها زمان کافی را برای آماده‌سازی ‌می‌دهد. در نتیجه در نتیجه افراد بیت کوین می‌خرند و با افزایش تقاضا، و از طرفی دیگر حرکت گاوی قیمت بیت کوین قبل از هاوینگ بالا می‌رود.
برخی دیگر کمی پیچیده‌تر فکر می‌کنند. آن‌ها می‌گویند که با آگاهی افراد از این اتفاق قابل پیش‌بنی، تقاضا برای بیت کوین بالا می‌رود و سرمایه‌گذران زمان کافی برای آماده‌سازی خواهند داشت. در نتیجه تاثیر هاوینگ بر قیمت بیت کوین (بخاطر این قابل پیش‌بینی بودن) قبل از رخ دادن اتقاف میافتد. برخی از این پدیده با نام پیشخور شدن یاد می‌کند.
حال این افراد می‌گویند که اگر قرار بود هاوینگ بر قیمت تاثیر داشته باشد، باید تا الان تاثیر خود را می‌گذاشت. در حالی که چنین تاثیری مشاهده نشده است. بنابراین اگر تا کنون تاثیری نداشته است، پس از این به بعد، و با رخ دادن آن در ۲۳ اردیبهشت هم اتفاقی نخواهد افتاد.

۵. چرا استخراج کنندگان پاداش دریافت می‌کنند؟

دلیل آن این است که، بدون این پپاداش بلاک‌ها، بیت کوین اصلا کار نمی‌کند.
هسو (Hasu) به عنوان یک محقق مستقل می‌گوید که بیت‌کوین، تنها در صورتی می‌تواند به فعالیت خود ادامه دهد که بلاکچین آن بتواند پاسخ به دو سوال را بدهد. چه کسی مالک چه چیزی است، و در چه زمانی مالک آن چیز است. بخش اول، «چه کسی مالک چه چیزی است؟» با رمزنگاری حل می‌شود. فقط صاحب یک کلید خصوصی می‌تواند بیت کوین را خرج کند.
هسو توضیح می‌دهد: «بخش دوم، یعنی چه زمانی صاحب آن چیز است، چالش بزرگی است. اگر به این سوال پاسخ داده نشود، مردم می‌توانند بیت کوین‌های خود را دو بار خرج (double-spend) کنند.
بدون پاداش بلاک، شبکه در هرج و مرج خواهد بود. هسو توضیح می‌دهد که استخراج‌کنندگان، در صورت داشتن قدرت محاسباتی کافی، خودشان می‌توانند به دو طریق به شبکه حمله کنند! اول با دوبار خرج کردن بیت ‌کوین‌ها و دوم با متوقف کردن معاملات و جلوگیری ار انجام شدن آن‌ها. اما باید گفت که آن‌ها هیچ کدام از این کارها را نمی‌کنند. چرا که در این صورت پاداش بلاک را از دست خواهند داد.
به عبارت دیگر ، در صورت عدم پیروی از قوانین ، استخراج کنندگان پول از دست می‌دهند
هرچه قدرت پردازشگرهای محاسباتی بیشتری به سمت بیت کوین هدایت شود، حمله به آن سخت تر می‌شود. چرا که یک مهاجم برای اجرای حمله بخ شبکه، نیاز به بخش قابل توجهی از این قدرت پردازشی، معروف به hashrate دارد. هرچه استخراج کنندگان از طریق پاداش‌های بلوکی بتوانند درآمد بیشتری کسب کنند، قدرت استخراج بیشتری به سمت بیت کوین می‌آید و به این ترتیب از شبکه محافظت می‌شود.
هاوینگ بیت کوین چیست | زمان هاوینگ بیت کوین | تاثیر هاوینگ بر قیمت بیت کوین

۶. چه اتفاقی می‌افتد اگر پاداش بلاک‌ها کم شود؟

دقیقا به همین خاطر است که کاهش دوره‌ای پاداش‌ها به یک نگرانی و مساله تبدیل می‌شود. اگر پاداش بلاک‌ها کاهش یابد، امنیت شبکه چگونه تامین خواهد شد؟!
استخارج کنندگان برای ادامه دادن به استخراج (یا در واقع تایید یا رد تراکنش‌های شبکه) باید انگیزه یا محرک داشته باشند. آنها باید حقوق بگیرند 🙂 . هیچ استخراج کننده‌ای محض رضای خدا رایانه‌های گرانقیمت و هزینه برق و انرژی خود را صرف این کار نمی‌کند. این در حالی است که بالاخره در نهایت این پاداش به صفر می‌رسد (در سال ۲۱۴۰). ولی باید گفت که علاوه بر پاداش بلاک‌ها، استخراج کنندگان از محل هزینه تراکنش (Transaction fees) نیز درآمد دارند. انتظار می‌رود با سقوط پاداش بلاک‌ها، هزینه‌های انتقال به منبع مهمی از پاداش استخراج کنندگان تبدیل شود.
ناکاموتو می‌نویسد: «در طی چند دهه وقتی که پاداش بلاک‌ها خیلی کم شود، هزینه تراکنش تبدیل به منبع صلی درآمد برای نودهای شبکه (یا استخراج کنندگان)‌ می‌شود. من مطمئن هستم که در طی ۲۰ سال، حجم معاملات یا خیلی خیلی زیاد باشد، یا اصلا معامله‌ای در کار نباشد!»
اما مدت طولانی است که محققان بیت کوین در حال بررسی این موضوع هستند که آیا هزینه تراکنش برای انگیزه دادن برای استخراج کنندگان کافی هست یا نه. یک دیدگاه آت است که هزینه تراکنش‌ها باید در طول زمان افزایش یابد تا بتوان امنیت شبکه را تضمین کرد.
پیش بینی اینکه چه اتفاقی خواهد افتاد غیرممکن است، اما اگر سیستمی می‌خواهیم که بتواند ۱۰۰ سال عمر کند، باید برای بدترین حالت آماده باشیم.
دوبروسکی (Dubrovsky) می‌گوید: «حل این مشکل بدون استفاده از هزینه‌های تراکنش بسیار بالا ممکن نست. چرا که شبکه بیت کوین نمی‌تواند تعداد تراکنش‌های زیادی را در زمان انجام دهد، بنابراین باید از محل همان تراکنش‌های کم، هزینه تراکنش بالای را دریفات کند.»
همانطور که در بالا گفته شد، این پاداش‌های استخراج است که قدرت محاسبات بیشتری را به بیت کوین می‌کشاند، و آن را در برابر حمله‌هایی که سعی دارند قوانین شبکه را زیر پا بگذارند حفظ کند. در واقع، علت آنکه استخراج کنندگان استخراج می‌کنند، به دست آوردن پاداش شبکه است، نه هزینه تراکنش‌ها. محل اصلی درآمد پاداش اتس. معلوم نیست که آیا پاداش‌های کم در آینده حتی در صورت وجود هزینه‌های شبکه، برای استخراج کندگان کافی باشد یا نه.
هسو می‌گوید: «من فکر نمی‌کنم که این هاوینگ امنیت شبکه بیت کوین را به میزان قابل توجهی کاهش دهد. اما در ۸ یا ۱۲ سال، این موضوع واقعا مهم خواهد شد.»
بخشی از مشکل این است که با وجود گذشت بیش از یک دهه از تولد بیت کوین، هنوز هم بازار در حال محاسبه هزینه‌ی واقعی محافظت محافظت از شبکه در برابر مهاجمان است.
دوبروسکی (Dubrovsky) بحث می‌کند که: «هیچ کسی نمی‌داند که برای امن نگه داشتن شبکه بیت‌کوین، چه سطح از امنیت توسط استخارج کنندگان نیاز است. در حال حاضر، بیت کوین چیزی در حدود ۵ میلیارد دلار گردش مالی دارد و تا کنون هیچ حمله موفقی صورت نگرفته است. با این حال، هیچ پیش‌بینی از ارزش و قیمت این امنیت وجود ندارد. ممکن است بیت کوین بیش از حد امنیت دارد و بیش از حد به استخارج کنندگان پرداخت می‌کند. برای پیدا کردن حداقل امنیت مورد نیاز برای جلوگیری از حملات، باید پاداش‌های استخراج کنندگان را تا جای که حملات موفقی صورت گیرد کاهش داد. حال هیچ کسی نمی‌داند که با کاهش پاداش بلاک‌ها، و از بین رفتن انگیزه و محرک استخارج کنندگان، چه بلایی به سر امنیت شبکه خواهد آمد»
او ادامه می‌دهد: «مطمئنا این موضوع برای بیت کوین فاجعه‌بار خواهد بود، اما اگر پاداش کاهش یابد و جامعه بیت کوین کاری برای آن نکند، واقعا رخ دادن چنین سناریویی محتمل است.»
هسو می‌گوید که «امیدوار است» که هزینه تراکنش‌ها به اندازه‌ای کافی باشد که امنیت شبکه در آخر حفظ شود.
هسو می‌گوید: «انگیزه حمله به شبکه بیت کوین، نسبت به ۵ سال پیش بیشتر است. در حال حاضر [رئیس جمهور ایالات متحده] ترامپ، [رئیس جمهور شی جینپینگ] و دیگر رهبران جهان از بیت کوین انتقاد می‌کنند. هرچه بیت کوین بیشتر رشد کند، بیشتر ممکن است که مورد حمله قرار گیرد.»
این موضوع البته در حال حاضر شاید خیلی مهم نباشد، اما چند سال دیگر واقعا مهم خواهد شد. هسو گفت: «پیش بینی اینکه چه اتفاقی خواهد افتاد غیرممکن است، اما اگر ما سیستمی را می‌خواهیم که ۱۰۰ سال عمر کند، باید برای بدترین حالت آماده باشیم.

۷. جمع‌بندی

هاوینگ، یک فرایند بلندمدت، خسته‌کننده و قابل‌پیش‌بینی، برای حفظ ارزش بیت کوین در طول زمان، و کنترل تورم حاصل از عرضه بیت کوین‌های جدید است. هاوینگ این کار را با کند کردن نرخ توزیع در طول زمان انجام می‌دهد. تاثیر هاوینگ بر قیمت، در دوبار قبلی مثبت بوده است. اما اینکه آیا این بار نیز تاثیر مثبتی خواهد داشت، جای سوال دارد.

Summary: Bitcoin was invented by the anonymous Satoshi Nakamoto as recently as 2008, but it is backed up by a rich intellectual foundation. For instance, The 1776 First Amendment separates church and state, and contemporary American liberation psychologist Nozomi Hayase (2020) argues that money and state should similarly be separated. Just as Isaac Newton’s study of alchemy gave rise to the international gold standard, so has the anonymous creator Satoshi Nakamoto's desire for a “modernized gold standard” given rise to Bitcoin. Indeed, Bloomberg's 2020 report confirms Bitcoin to be gold 2.0. Montesquieu (1774) asserted that laws that secure inalienable rights can only be found in Nature, and the natural laws employed in Bitcoin include its consensus algorithm and the three natural laws of economics (self-interest, competition, and supply and demand). J.S. Mill (1859) preferred free markets to those controlled by governments. Ludwig von Mises (1951) argued against the hazards of fiat currency, urging for a return to the gold standard. Friedrich Hayek (1984) suggested people to invent a sly way to take money back from the hands of the government. Milton Friedman (1994) called for FED to be replaced by an automatic system and predicted the coming of a reliable e-cash. James Buchanan (1988) advocated a monetary constitution to constrain the governmental power of money creation. Tim May (1997) the cypherpunk proclaimed that restricting digital cash impinges on free speech, and envisioned a stateless digital form of money that is uncensorable. The Tofflers (2006) pictured a non-monetary economy. In 2016, UCLA Professor of Finance Bhagwan Chowdhry even nominated Satoshi for a Nobel Prize.
Full Text:
Separation between money and state
The 1791 First Amendment to the U.S. Constitution enshrines free speech and separates church and state, but not money and state. "Under the First Amendment, individuals’ right to create, choose their own money and transact freely was not recognized as a part of freedom of expression that needs to be protected," Japanese-American liberation psychologist Nozomi Hayase (2020) points out (1).
The government, banks and corporations collude together to encroach upon people's liberties by metamorphosing their inalienable rights into a permissioned from of legal rights. Fiat currencies function as a medium of manipulation, indulging big business to generate market monopolies. "Freedom of expression has become further stifled through economic censorship and financial blockage enacted by payment processing companies like Visa and MasterCard," to borrow Hayase's (2020) words.
Satoshi is a Modern Newton
Although most famous for discovering the law of gravity, Isaac Newton was also a practising alchemist. He never managed to turn lead into gold, but he did find a way to transmute silver into gold. In 1717, Newton announced in a report that, based on his studies, one gold guinea coin weighed 21 shillings. Just as Isaac Newton’s study of alchemy gave rise to the international gold standard, so has the desire for a “modernized gold standard” given rise to Bitcoin. "In a way, Satoshi is a modern Newton. They both believed trust is best placed in the unchangeable facets of our economy. Beneath this belief is the assumption that each individual is their own best master," as put by Jon Creasy (2019) (2).
J.S. Mill: free markets preferable to those controlled by governments
John Stuart Mill (1806-1873) the great English philosopher would be a Bitcoiner were he still around today. In On Liberty (1859), Mill concludes that free markets are preferable to those controlled by governments. He argues that economies function best when left to their own devices. Therefore, government intervention, though theoretically permissible, would be counterproductive. Bitcoin is precisely decentralized or uncontrolled by the government, unconfiscatable, permissonless, and disinflationary. Bitcoin regulates itself spontaneously via the ordinary operations of the system. "Rules are enforced without applying any external pressure," in Hayase's (2020) words.
Ludwig von Mises (1958): Liberty is always Freedom from the Government
In The Free Market and its Enemies, theoretical Austrian School economist Ludwig von Mises (1951) argues against the hazards of fiat currency, urging for a return to the gold standard. “A fiat money system cannot go on forever and must one day come to an end,” Von Mises states. The solution is a return to the gold standard, "the only standard which makes the determination of the purchasing power of money independent of the changing ideas of political parties, governments, and pressure groups" under present conditions. Interestingly, this is also one of the key structural attributes of Bitcoin, the world’s first, global, peer-to-peer, decentralized value transfer network.
Actually, Bloomberg's 2020 report on Bitcoin confirms that it is gold 2.0. (3)
Von Mises prefers the price of gold to be determined according to the contemporaneous market conditions. The bitcoin price is, of course, determined across the various global online exchanges, in real-time. There is no central authority setting a spot price for gold after the which the market value is settled on among the traders during the day.
Hayek: Monopoly on Currency should End
Austrian-British Nobel laureate Friedrich Hayek’s theory in his 1976 work, Denationalization of Money, was that not only would the currency monopoly be taken away from the government, but that the monopoly on currency itself should end with multiple alternative currencies competing for acceptance by consumers, in order "to prevent the bouts of acute inflation and deflation which have played the world for the past 60 years." He forcefully argues that if there is no free competition between different currencies within any nation, then there will be no free market. Bitcoin is, again, decentralized, and many other cryptocurrencies have tried to compete with it, though in vain.
In a recently rediscovered video clip from 1984, Hayek actually suggested people to invent a cunning way to take money out of the hands of the government:- “I don’t believe we shall ever have a good money again before we take the thing out of the hands of government, that is, we can’t take them violently out of the hands of government, all we can do is by some sly roundabout way introduce something they can’t stop” (4). Reviewing those words 36 years hence and it is difficult not to interpret them in the light of Bitcoin.
Milton Friedman Called for FED to be Replaced by an Automatic System
Nobel laureate economist Milton Friedman (1994) was critical of the Federal Reserve due to its poor performance and felt it should be abolished (5). Friedman (1999) believed that the Federal Reserve System should ultimately be replaced with a computer program, which makes us think of the computer code governing Bitcoin (6).[\](https://en.wikipedia.org/wiki/Criticism_of_the_Federal_Reserve#cite_note-:2-12) He (1970) favored a system that would automatically buy and sell securities in response to changes in the money supply. This, he argued, would put a lid on inflation, setting spending and investment decisions on a surer footing (7). Bitcoin is exactly disflationary as its maximum possible supply is 21 million and its block reward or production rate is halved every four years.
Friedman passed away before the coming of bitcoin, but he lived long enough to see the Internet’s spectacular rise throughout the 1990s. “I think that the Internet is going to be one of the major forces for reducing the role of government," said Friedman in a 1999 interview with NTU/F. On the same occasion, he sort of predicted the emergence of Bitcoin, "The one thing that’s missing, but that will soon be developed, is a reliable e-cash, a method whereby on the Internet you can transfer funds from A to B, without A knowing B or B knowing A." (8)
Of course, Friedman didnt predict the block chain, summed up American libertarian economist Jeffery Tucker (2014). “But he was hoping for a trustless system. He saw the need. (9).
Bitcoin Computer Code as Constitution in the Buchananian Sense
American economist cum Nobel laureate James Buchanan (1988) advocates constitutional constraints on the governmental power to create money (10). Buchanan distinguishes a managed monetary system—a system “that embodies the instrumental use of price-level predictability as a norm of policy”—from an automatic monetary system, “which does not, at any stage, involve the absolute price level” (Buchanan 1962, 164–65). Leaning toward the latter, Buchanan argues that automatic systems are characterized by an organization “of the institutions of private decision-making in such a way that the desired monetary predictability will emerge spontaneously from the ordinary operations of the system” (Buchanan 1962, 164). Again, "Bitcoin regulates itself through the spontaneous force of nature, flourishing healthy price discovery and competition in the best interest of everyone" (Hayase 2020).
Shruti Rajagopalan (2018) argues that the computer code governing how the sundry nodes/computers within the Bitcoin network interact with one another is a kind of monetary constitution in the Buchananian sense. One of Buchanan's greatest inputs is to differentiate the choice of rules from the choice within rule (Buchanan 1990). One may regard the Bitcoin code as a sort of constitution and "the Bitcoin network engaging in both the choice of rules and choice within rules" (Rajagopalan 2018) (11).
Tim May: Restricting Digital Cash may Impinge on Free Speech
Cypherpunks are activists who since the 1980s have advocated global use of strong cryptography and privacy-enhancing technologies as a route to social and political liberation. Tim May (Timothy C. May [1951-2018]), one of the influential cypherpunks published The Crypto Anarchist Manifesto in September 1992, which foretold the coming of Bitcoin (12). Cypherpunks began envisioning a stateless digital form of money that cannot be censored and their collaborative pursuit created a movement akin to the 18th Enlightenment.
At The 7th Conference on Computers, Freedom, and Privacy, Burlingame, CA. in 1997, Tim May equated money with speech, and argued that restricting digital cash may impinge on free speech, for spending money is often a matter of communicating orders to others, to transfer funds, to release funds, etc. In fact, most financial instruments are contracts or orders, instead of physical specie or banknotes (13).
Montesquieu: Laws that secure inalienable rights can only be found in Nature
In his influential work The Spirit of Laws (1748), Montesquieu wrote, “Laws ... are derived from the nature of things … Law, like mathematics, has its objective structure, which no arbitrary whim can alter". Similarly, once a block is added to the end of the Bitcoin blockchain, it is almost impossible to go back and alter the contents of the block, unless every single block after it on the blockchain is altered, too.
Cypherpunks knew that whereas alienable rights that are bestowed by law can be deprived by legislation, inalienable rights are not to be created but can be discovered by reason. Thus, laws that secure inalienable rights cannot be created by humankind but can be found in nature.
The natural laws employed in Bitcoin to enshrine the inalienable monetary right of every human being include its consensus algorithm, and the three natural laws of economics (self-interest, competition, and supply and demand) as identified by Adam Smith, father of modern economics.
Regarding mathematics, bitcoin mining is performed by high-powered computers that solve complex computational math problems. When computers solve these complex math problems on the Bitcoin network, they produce new bitcoin. And by solving computational math problems, bitcoin miners make the Bitcoin payment network trustworthy and secure, by verifying its transaction information.
Regarding economic laws, in accordance with the principle of game theory to generate fairness, miners take part in an open competition. Lining up self-interests of all in a network, with a vigilant balance of risk and rewards, rules are put in force sans the application of any exterior pressure. "Bitcoin regulates itself through the spontaneous force of nature, flourishing healthy price discovery and competition in the best interest of everyone," to borrow the words of Hayase (2020).
A Non-monetary Economy as Visualized by the Tofflers
In their book, Revolutionary Wealth (2006), futurists Alvin Toffler and his wife Heidi Toffler toy with the concept of a world sans money, raising a third kind of economic transaction that is neither one-on-one barter nor monetary exchange. In the end, they settle on the idea that the newer non-monetary economy will exist shoulder-to-shoulder with the monetary sector in the short term, although the latter may eventually be eclipsed by the former in the long run. What both the Tofflers' The Third Wave (1980) and Revolutionary Wealth bring into question is the very premise of monetary exchange. The vacuum left over by cash in such a non-monetary economy may be filled up by Bitcoin as a cryptocurrency.
Satoshi Nakamoto Nominated for Nobel Prize by UCLA Finance Prof.
UCLA Anderson School Professor of Finance Bhagwan Chowdhry nominated Satoshi Nakamoto for the 2016 Nobel Prize in Economics on the following grounds:-
It is secure, relying on almost unbreakable cryptographic code, can be divided into millions of smaller sub-units, and can be transferred securely and nearly instantaneously from one person to any other person in the world with access to internet bypassing governments, central banks and financial intermediaries such as Visa, Mastercard, Paypal or commercial banks eliminating time delays and transactions costs.... Satoshi Nakamoto’s Bitcoin Protocol has spawned exciting innovations in the FinTech space by showing how many financial contracts — not just currencies — can be digitized, securely verified and stored, and transferred instantaneously from one party to another (14).

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.

Scaling resources here, and of course the whitepaper that started it all.

2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
