✅ If you look at other popular cryptocurrencies, they have one very unpleasant disadvantage. To create a transaction through an official node, you need to upload your private key (wallet.dat file in the case of Bitcoin) or a mnemonic phrase (as in the case of NXT or PRIZM).

✅ Thus, when using the node, the mnemonic phrase / private keys are transmitted to the network. This means, for example, in the event of some kind of attack on the network or collusion of the majority of the node holders, the private keys can be compromised. Given that the blockchain should eliminate the need to trust anyone, this fact is unacceptable.

✅ Therefore, the UMI network uses an alternative solution. To provide the highest possible level of security, the UMI node does not require a mnemonic phrase to make transactions. Moreover, in fact, the network does not imply the ability to create transactions directly through the node at all. Separate libraries / SDKs are responsible for this. By the way, the availability of these tools (libraries) in the public domain greatly simplifies the process of developing wallets and other applications based on UMI.

✅ Thus, the UMI nodes do not transmit the mnemonic phrase to the network in any form. Secret data does not leave the borders of your device and remains safe.

✅ Also, just in case, we remind you that thanks to the encryption algorithm, the mnemonic phrase that you enter when you log in to the UMI wallet cannot be calculated.

A Complete Guide to Cryptocurrency Airdrops

The first guide to cryptocurrency airdrops in Italian with all the information on the vast world of airdrops and bounties.
Before going into this guide to cryptocurrency airdrops, we must make a small premise: the token is the representative unit of measurement of a project (dApps) relating to an ICO / IEO that relies on an already existing blockchain. Ethereum in our case. The coin is instead the unit of measurement of the blockchain itself (Ether in the case of Ethereum). Both fall within the generically defined field of cryptocurrencies (or cryptocurrencies). IEOs differ from ICOs in that they rely on an exchange for the marketing and dissemination phase.

Cryptocurrency AirDrops are in effect a marketing tool used to spread and make known the project of an ICO / IEO through the distribution of a certain number of tokens free of charge. It is possible to get free tokens after purchasing a certain amount of them in the pre-Ico phase, but we will focus only on the free Airdrops which provide practically no cash outlay.

With AirDrop, the operations to be performed are notoriously reduced to a minimum: subscribe to a Telegram channel, register with a valid email address on a main site or download an app from the Android or Apple stores. At your discretion, you can try to spread the most profitable ICOs as much as possible to obtain bonuses from the referral program.


Viral distributive marketing.
On balance, the dissemination of tokens aims to make the project reach the maximum possible virality. If this fails, you will obviously not receive anything. Or in any case the value of the tokens will be close to zero. So it's not worth going crazy to sign up for all the Airdrops and follow their progress week after week, but a selection of the best must be made.

If, on the other hand, the popularity of the ICO / IEO increases, the value of the token will also rise accordingly. The tokens you will get through the Airdrop will not be immediately exchangeable on exchanges, unlike those purchased in the pre-ICO / IEO phase, but you will have to wait for the ICO / IEO to finish. Sometimes it is worth keeping a portion of the tokens linked to the most important projects because their price could rise exponentially, even after a long time.

The most widespread standard for the creation of tokens is the ERC-20 on the Ethereum blockchain. You will therefore need to have a wallet that is compatible with this format. At the end of our complete guide to cryptocurrency airdrops we will list some of them describing their use.

Other types of Token, much less commonly, are based on the Waves, Tron or Stellar blockchain.
To convert the Tokens into Ethereum you will have to move them to an exchange that exchanges the related crypto or have a wallet that has an internal exchange. We will list the most popular ones in both the Desktop and Mobile versions at the bottom of the guide. You will be able to follow the trend of the tokens both on the exchange or on the classic coinmarketcap.com.

Guide to cryptocurrency airdrops: bounties.
The Bounty, unlike the Airdrop, always allows you to receive free tokens but only as a result of an action that must be performed, such as retweeting, following a specific page on Facebook and in general advertising on social media or forums, writing on the blog, make a video, etc ...

For convenience, we will use the term AirDrop in both cases.


What you need to be able to join the airdrops:

1 - An Erc-20 compatible Ethereum wallet. We use Exodus for the desktop and Eidoo for the mobile. The advantage that the Eidoo wallet offers is that you will always see which tokens have arrived there. For other wallets, we recommend following the next steps.

2 - Know how Etherscan.io, MyEtherwallet.com or the Metamask extension for the browser works.

The first site allows you to periodically check if the tokens have been credited to you quickly directly from the browser. It will be enough to enter the address of your Ethereum wallet in the search box at the top right and on the next page select Token Transfer to check which and how many tokens you have won.
Etherwallet and Exodus.
In this guide, the cryptocurrency airdrops also want to prepare the user for the use of the sites or applications necessary to adhere without difficulty to the distribution of tokens.

The Etherwallet site allows you to transfer tokens from one Ethereum address to another, whether it's an exchange or your wallet. In order to access the wallet in which the tokens have been credited, you must select "Send ether and token" in the top menu and on the following page choose which method to access the wallet: mnemonic phrase (12-word passphrase), Keystore if you have decided to open a wallet directly on the site (in this case you will need the password you entered at registration), the private key of the wallet.

In order to download the Exodus private key, press CTRL + SHIFT + D to open the hidden menu. From here select Exodus-> Developer-> Assets-> Ethereum-> Export Private Keys to download the private key with which to access your wallet from the MyEtherwallet.com website. To download the Eidoo private key, follow the procedure described at the following link: https://helpdesk.eidoo.io/hc/it/articles/360018609212-Come-recupero-la-chiave-privata-del-mio-wallet-Ethereum -


Once the wallet has been accessed, it will be sufficient to enter the address of the destination wallet, the amount of tokens to be transferred and the type. Recall that to generate the transaction it is necessary to "gas" (in practice a small amount of Ether that must always be present in the wallet) which goes to reward the miners who certify all operations with their work.

At the bottom right you will see your token list. If, on the other hand, the possibility that a token visible on Etherscan is not present in the list should occur, you must proceed as follows: click on Add another token, enter the address of the contract, the token symbol and the decimals and the game is done. You can see these data by returning to Etherscan.io: click on the name of your token on the right and on the next page the exact name of the token will be shown (which you will already know by now), the ERC-20 contract and the decimals.

Metamask.
With Metamask, the operation is almost identical. Once logged in with your Ethereum wallet, click on the menu on the left, select add token at the bottom and then choose Custom Token. Then enter the token data as described for MyEtherwallet.

3 - A valid email address. Do not use or create addresses that you will no longer access because you will probably be contacted in the future for any checks.

4 - A Telegram account for any registrations and to follow some Airdrop channels. We warn you: it is a real chaos for those who don't chew on the cryptocurrency sector, coins, tokens and much more.

5 - A Twitter account to follow and retweet in case you are asked.


The tokens will become visible at the end of the Airdrop and will actually become yours at the end of the ICO, the date on which they can finally be exchanged. But, as already mentioned, you could decide and keep all or part of them.

The sites or Telegram channels in which the Airdrops are listed are literally endless and often there is the risk of choosing one that pays little dictated by the haste to try the news.

An AirDrop to be safe must be based on a real project described in detail on a dedicated site, have Twitter or Telegram accounts, be followed on various specialized forums, etc ... Stay away from infamous AirDrop that promise you seas and mountains or ask you personal data by email. Never provide your wallet's private key.

And keep following us so you don't miss any more driving updates!

How to Cold Store Your Cryptocurrency for Safekeeping

According to CipherTrace (which specializes in litigation tools and services for cryptographic markets), between 2018 and 2019, the amount of theft from cryptographic wallets exceeds $2 billion. Thefts and break-ins are caused by a variety of reasons: simple incompetence in cryptographic storage, as well as by companies that provide storage services. It is not unusual for holders of crypto currency to lose access to their wallets by themselves, one of the last known cases occurred in Ireland: ,57 million dollars couldn’t be confiscated from a detained drug dealer, which were stored in bitcoins. The problem was that the wallets keys were lost.
The most secure way is a cold storage — all account data and private keys are kept offline and all transactions are manual. This storage method is great because it is fully protected from hacking and interception of data, but it is not suitable for those who make daily transfers of cryptocurrency, it is simply inconvenient.
If you compare “cold and hot” wallets, you can give a simple example: A hot wallet can be compared to a wallet that can be lost and stolen. But you can always access your funds. A cold wallet is safe, and access to it is not permanent. You can also take or put money, but it will require a special code.
In this article we will tell you about the most popular types of cold wallets and we will analyze their pros and cons.

Types of cold wallets

All cold wallets have one common thing — the data is stored offline. However, there are several types of cold wallets, which differ in the degree of protection, physical embodiment and cost of the wallet.

Desktop wallet

Desktop wallets are also known for a high level of protection, in addition to the ability to store crypto currency offline. There are so-called “light” wallets weighing less than 1 gb, and “heavy” wallets weighing more than 1 gb. Two of the desktop wallets can be distinguished:

Exodus Wallet

Multicurrency wallet. It was created in 2016 and supports more than 100 crypto currencies, since 2019 has a phone application. The wallet allows you to export private keys that are created locally, and then to upload them back. Private keys can be discounted to removable media and downloaded only when the transaction is completed. If the user decides to leave private keys on the same computer where the wallet is located, keys are securely encrypted. In order to use your wallet ,there is no need to register or to download the entire blockchain — synchronization is taking place online. In addition to wallet services Exodus Wallet provides an integrated crypto-exchange. The installation file weighs 85 mb.

Bitcoin Core

Bitcoin Core is the official Bitcoin wallet. The size of the wallet is 160 gb, but according to the developers of the company, it’s better to give it a separate winchester with the size of 500 gb. From the security viewpoint, it’s suggested to install a security code or a seed phrase, which may consist 8 words. It is also suggested to copy wallet.dat file. — private wallet key, which will allow you to restore access to your funds.

Hardware wallets

Appears like a regular flash drive with an interface (screen, control keys). This wallet can safely store information about the balance and keys, full functionality is available only when connected to a computer, but the latest models have a special button that allows you to confirm the transaction without connecting to a PC. Each time the device offers to generate a new code-password to confirm the transaction, which significantly reduces the probability of hacking. After generating the code, you need to set a mnemonic phrase (seed) — it consists of 12 or 24 words, which are not related to each other in any way. Such type of wallets has a special protection system that allows you to connect even to potentially infected PCs. The wallets themselves won’t be affected by malware.
The obvious cons of hardware wallets are the following:
  1. It is also possible to lose a device that is so small in size.
  2. A physical device can easily fail due to a variety of damages.
  3. It is not recommended to buy such wallets from “hand”, even from friends, as they can be pre-installed with malware.
As you can see, storing crypto currency with a hardware wallets is very safe and secure, however you should take care about the device. Many people who hold a large amount of crypto currency, in order to not to lose a hardware wallet, store it in a safe deposit box, depriving someone of access to it.

Popular Hardware Wallets models

Trezor One

The first hardware wallet produced in 2013 by the Czech company Satoshi Labs. The device has an OLED display with a pin code, public addresses and Seed phrases. Trezor One has won recognition from users due to its multicurrency and affordable price ($65), it is also considered one of the most secure hardware wallets.
Ledger Nano S
The wallet was released in 2016 by the French company Ledger SAS. Distinctive feature from the other wallets, is the Secure Element controller, which meets banking standards and is certified CC EAL 5+. Also, in order to work with each crypto currency you need to install a special application for this currency on the device, it is not quite convenient, however more secure. The average price of the device is $85.
KeepKey
The purse was released in 2015 in the U.S.. Distinctive feature is OLED display — 256 by 64 pixels. Due to this, you can fully see both the address of the wallet, and the seed phrase. Also, the wallet has a built-in exchange service ShapeShift — an opportunity to exchange crypto currency without entering the exchange. The average price of the device is $50.
BitBox01
Ionos Schnelly’s wallet was invented in Switzerland. In size it’s almost the most compact among all representatives of the hardware wallets. A distinctive feature is the availability of a backup — the card can be multiplied and kept in several places, by analogy with the seed-phrase. In November 2020, support for these wallets will be discontinued, but all owners will be given a 30% discount on the new model. The average price of the device is $55.
CoolWalletS
Developed in Taiwan by CoolBitX, which has long been manufacturing components for Visa and MasterCard. As well as Ledger Nano S has a security standard CC EAL 5+. This wallet works only through smartphones, connecting to them through Bluetooch. The average price of the device is $100.

Paper Wallet

In the age of technological process, plain paper has become a rather reliable method for storing cryptocurrency. With the help of special services, such as bitaddress.org, you can generate public and private keys, then writing them down on paper. You can also print keys as a QR code. To accept transactions with such a wallet, you provide the sender with a public key. To access the funds, you need to find any online wallet that supports your crypto currency. Enter your private key into your online wallet, thus integrating your funds into the system. However, you should understand that after this procedure your wallet will become “hot”.
The best of this storage method — paper wallet is free, its safety depends only from you. When storing a paper wallet to protect it from the fire, water and aging. Also, do not tell other people about where your paper wallet is hidden.
The disadvantages of this storage:
  1. If your wallet is lost, it will be impossible to restore it.
  2. Exposed to a physical damage.
  3. After sending the transaction, you will have to create a new cold wallet.

Offline transaction signature

For this storage method, you will need two PCs. The essence is that the secret keys are never in contact with the Internet, but are stored digitally. Offline transaction method is suitable for people who do not make a daily transactions and have an access to two devices. The process is below:
  1. A hot wallet is installed on a PC with the Internet. The transaction is created without entering private keys and authorization.
  2. The file with transaction is copied and transferred to the second PC without Internet, where private keys are stored.
  3. The transaction is signed offline, copied and transferred back to the PC with the Internet.
In fact, you can do it with one PC and a USB drive. The USB drive will store private keys. Also, you can create a transaction without entering private keys and authorization, after disconnecting the Internet, connect the flash drive, sign the transaction, turn on the Internet. In this case, you should take care of the antivirus system.
The disadvantages of this method:
  1. Using two PCs or a USB drive involves a lot of actions, which is time consuming.
  2. You need to back up your keys in case your PC or flash drive fails.

Multi-signature wallet

This method implies the creation of a wallet, which can be only withdrawn on condition that the transaction is verified by a predetermined number of users. The maximum number of users who can hold private keys of the wallet- is 15. It is considered as one of the most reliable ways of storage, in fact private keys are not only stored offline, but also divided between different people. Often the wallet with multisignatures is used by large crypto-companies, whose management believes that individually employees can not spend the budget. Moreover, when creating this wallet, the number of required multisignatures is minimal. For example: if one of the six keys is lost, the remaining ones will be enough for the transaction.
The disadvantages of this storage:
  1. If most of the keys are lost, access to the funds cannot be restored.
  2. You will not be able to make transactions on your own without the participation of other key holders.

Private Key Fragmentation

The private wallet key consists of 64 symbols. The key is divided into several fragments. They don’t represent anything separately, but if you put all the fragments together, you can access the funds. The key fragments are similar to multisignatures, but in this case you don’t need a multisig-wallet, and the whole process can be done manually.
The disadvantages of this method:
  1. If one fragment is lost, access to funds will be lost.
  2. The maximum level of protection can only be reached when key fragments are distributed to different places, for example: bookshelf, safe deposit box, car. If you divide the key fragments and put them in different boxes — the required level of protection will not be achieved.
When writing down key fragments on paper, protect the key from fire, water and aging.

Conclusion

Digital currencies are not physically expressed and exist only in the digital code, so cold wallets that doesn’t have an access to the Internet, protect cryptocurrencies from the most important and common problem — hacker theft. However, holders of cold wallets need to understand that the safety of a private key depends only on them. There are different ways to store private keys outside the network, but each of them makes it difficult for the user to make transactions.
Hardware wallets that have been specifically designed for this purpose are considered to be the best option for storing cryptocurrencies. With their help it is possible both to store funds off the network and to make transactions easily, without risking the safety of a private key. If you use other cold wallets, it is recommended to combine them with hot wallets. Keep the required crypto currency for daily transfers on hot wallets, and keep all other crypto on cold wallets.

Wallet is showing grossly inaccurate amount of bitcoin?

So my laptop broke, and I had to get a new one.
I had a .json file backed up, as well as the mnemonic phrase.
I installed a fresh install of Wasabi on a new laptop, and now it's showing that I have about 1 bitcoin more than I know I have. (I've already verified this by looking at the amount publicly shown from the x pub on blockchain)
I've tried to spend the addresses I think are inaccurate, and get a error "HttpRequestException: Bad Request Missing inputs"
So obviously Wasabi is showing me that I have bitcoin that I have actually already spent.
So how do I solve this?
(Running on MacOS btw)

I started working with Ethereum and Bitcoin while pursuing my Bachelors in CS, got into a well-paying job in Samsung as software dev, left it to work on my Crypto security startup, Cypherock, with the aim of eliminating fear of loss of Crypto for mass adoption.

I started working with Ethereum and Bitcoin while pursuing my Bachelors in CS, got into a well-paying job in Samsung as software dev, left it to work on my Crypto security startup, Cypherock, with the aim of eliminating fear of loss of Crypto for mass adoption.
Hello everyone, I am Rohan Agarwal! I heard the word 'Bitcoin' for the first time around 2013-2014 but it didn’t creep up on the top of my mind until 2017.
It was during my college days in 2017 when I was mostly working on android apps and attending hackathons to satisfy the competitive edge in me that I met my friend and CTO of Cypherock - Vipul through a mutual friend. During the same time, I went down the crypto rabbit hole after being bugged by the idea of decentralisation. During the 2017 bull run, I was continuously researching and trading Bitcoin, Ethereum and various cryptocurrencies while conducting workshops, writing blogs about the space.
At the height of the 2017 bull market, I found that one of my friends couldn't recover his recovery phrase kept safe on paper due to an unfortunate house fire. At the same time, another one of the colleagues had kept his 24 word mnemonic phrase as a screenshot on his phone which got lost when the phone was corrupted. That's when I realized the need for a secure hardware wallet + with a recovery solution that caters to both data loss and data theft problems without a single point of failure.
To facilitate mass adoption, it is necessary that -
  1. Regular, non tech savvy people should be able to use and secure crypto without the fear of losing it.
  2. The solution to secure and recover crypto should be a non-custodial solution and the support should be open to all assets.
This was the belief that gave birth to Cypherock. Current hardware wallets secure the crypto but the unencrypted seed phrase on the paper becomes a single point of attack. We believe that seed phrases deserve the same level of security that your private keys have.
So, we used 2 of 4 Shamir Secret Sharing (with the option to change the threshold in future) along with tamper-resistant hardware to secure your private keys. Simply put, it is like Multi-sig but for your wallet recovery phrase. Practically, it’s much easier to use than multi-sig, if implemented correctly. Even Coinbase uses Shamir Secret Sharing to secure their own assets.
More on what we developed
- Each shard will be stored in a EAL6+ tamper resistant secure element chips. As comparison, your iPhone has the same level of security chip for securing fingerprints.
- Nothing will be stored in the X1 Wallet on which the computation will be done.
- Keys can be recovered by tapping any 2 out of the 4 cyCards on the X1 Wallet. Each cyCard can also be protected by a PIN just like your hardware wallet. The recovered keys are stored in a volatile memory on the X1 Wallet which gets wiped out as soon as the operation is done.
- You can store 3 wallet recovery phrases in a single product.
- The cyCards can be distributed around different places to increase security of the funds and protect against $5 wrench attacks.
What this means is without the knowledge of location of atleast 2 cyCards and the PIN, it is impossible for the hackers to steal your assets. We'll be able to support multiple blockchains (read: coins) using this along with other digital assets like your passwords, secrets, non Blockchain private keys etc. You can secure the cards by distributing it among trusted people or keeping it secure in different places that only you know of.
https://preview.redd.it/z259ydi5auj41.png?width=1920&format=png&auto=webp&s=c110361d35ac82647c21da50264fcaee923fbc65
It has been a hell of a ride to provide an optimal solution for the mnemonic phrase/seed phrase recovery issue, without compromising the security of the user or the ownership of the assets.
We recently got backed by Consensys which was a high point for us. It has been a huge journey for us coming from India, where blockchain or the related hardware isn't that big with consumers yet.
The product is in the testing phase and we have started with the pre-orders. You can book one today with >50% off and if you don’t like it, we will give you a full refund, no questions asked.
Small Example to show how it works:
  1. You entegenerate your mnemonic phrase on the device or any other sensitive information like passwords.
  2. You tap four cyCards on the device to make 4 shards of your phrases.You'll need any 2 of them to recover your keys or perform a transaction.
  3. The cyCards can be stored at different locations or kept with different people for security.
  4. It can solve the issue with inheritance too with proper management of keys. (PM or comment to know more on this).
  5. To conduct a transaction, tap 2 cards on the device. The keys will be generated on the X1 Wallet for the transaction in a volatile memory which will be wiped off once the transaction is done (no current generation wallet has this). This allows for the hardware to have similar security as of multi-sig with the possible support of every asset.
Any feedback appreciated.
TLDR: With the dream of making storage of seed phrase an easy solution for everyone, started out with Cypherock and in the process found out a solution for removing single point of failure and a way for easy crypto inheritance. Would love any help from the community to take this further.
If anyone would like to see the device functioning, they can refer to the following videos:

What this means is without the knowledge of location of atleast 2 cyCards and the PIN, it is impossible for the hackers to steal your assets. We'll be able to support multiple blockchains (read: coins) using this along with other digital assets like your passwords, secrets, non Blockchain private keys etc. You can secure the cards by distributing it among trusted people or keeping it secure in different places that only you know of.

It has been a hell of a ride to provide an optimal solution for the mnemonic phrase/seed phrase recovery issue, without compromising the security of the user or the ownership of the assets.
We recently got backed by Consensys which was a high point for us. It has been a huge journey for us coming from India, where blockchain or the related hardware isn't that big with consumers yet.
The product is in the testing phase and we have started with the pre-orders. You can book one today with >50% off and if you don’t like it, we will give you a full refund, no questions asked.
Small Example to show how it works:
  1. You entegenerate your mnemonic phrase on the device or any other sensitive information like passwords.
  2. You tap four cyCards on the device to make 4 shards of your phrases.You'll need any 2 of them to recover your keys or perform a transaction.
  3. The cyCards can be stored at different locations or kept with different people for security.
  4. It can solve the issue with inheritance too with proper management of keys. (PM or comment to know more on this).
  5. To conduct a transaction, tap 2 cards on the device. The keys will be generated on the X1 Wallet for the transaction in a volatile memory which will be wiped off once the transaction is done (no current generation wallet has this). This allows for the hardware to have similar security as of multi-sig with the possible support of every asset.
Any feedback appreciated.
TLDR: With the dream of making storage of seed phrase an easy solution for everyone, started out with Cypherock and in the process found out a solution for removing single point of failure and a way for easy crypto inheritance. Would love any help from the community to take this further.
If anyone would like to see the device functioning, they can refer to the following videos:

ETHEREUM FRONTEND JAVASCRIPT APIS: WHAT YOU NEED TO KNOW

ETHEREUM FRONTEND JAVASCRIPT APIS: WHAT YOU NEED TO KNOW

https://preview.redd.it/9djdo90nx9051.jpg?width=2400&format=pjpg&auto=webp&s=54ca700da20bac0692ed294a31e75cfefb96f671
Blockchain has emerged as a popular technology, and if you are planning to make a career in this field, then there are various certification programs. When we talk about Blockchain, then it becomes important to mention about Ethereum. It is a cryptocurrency and an open-source platform as well. There has been some great development in this field, and those who are planning to learn about Ethereum must go for a certified Ethereum course.
Blockchain developers who are developing apps on Ethereum must know about the different frontend javascript which can simplify their task. In this blog, we will be highlight three such popular javascript APIs.
Ethereum Overview:
Ethereum emerged after Bitcoin and has now become a popular Blockchain platform. It is a cryptocurrency as well. It is an open-source software platform. Ethereum offers a flexible platform to the developer so that they can develop decentralized apps with ease.
Although scalability is a bit of an issue with Ethereum, in the current scenario, it is one of the best platforms for decentralized application development.
Looking at the broader spectrum and use of Blockchain, it has become a great career opportunity for many. Hence, option for certified Blockchain Developer is the right way to give your career the right boost.
What is API?
API is a set of the protocol which is used of building and integrating the applications across different platforms. APIs eventually simplifies app development and enables seamless interaction of your products and services with the user.
Popular frontend Javascript APIs:
Web3.js- This is a collection of libraries which empowers you to connect with remote Ethereum node. It is achieved by using HTTP or IPC connection. This is used for the following :

  1. Send ether from one account to another
  2. Interact with smart contracts
  3. Retrieve user account
It interacts with Ethereum Blockchain with JSON RPC protocol. A copy of all the data and code is present on the Blockchain. The API requests an individual Ethereum node with JSON RPC to read and write data to the network.
Ethers.js
Another frontend javascript is Ethere.js, which is used by most of the decentralized application developers owing to its features and functionalities. It has the following main features:

  1. It is open source
  2. It is completely safe as it keeps private keys restricted to the clients
  3. You can import and export using JSON wallets which again adds to the security feature
  4. Import and export BIP 39 mnemonic phrases
  5. You can connect to Ethereum nodes via JSON-RPC, MetaMask, INFURA, or Etherscan.
  6. It is completely TypeScript ready
  7. It offers complete functionality for all Ethereym needs
  8. Extensive documentation
  9. It has a huge collection of test cases
  10. It has an MIT Licence.
If you are looking for another API to develop javascript with Ethereum, then you must consider Ether.js. It is loaded with features that any Blockchain developer would require. The library is designed in such a way that it matches the need of the client. With the use of ether.js, it becomes easier to write javascript-based wallets.
Light.js
The third entrant in our list is light.js. It provides high-level tools which are used for developing efficient Dapps on the light client. This is also a great alternative to web3.js. It works with remote nodes and makes it easy for a developer to build decentralized applications with ease.
Here it becomes important to mention that light.js chooses the best pattern which works with light clients, it listens to headers and makes API calls on a new header an ensures that network calls are not extreme.
The end objective is to put up a high-level library such that the decentralized app developers can make use of this and create apps.
Besides, these there are other APIs like Web3-wrapper can also be used by blockchain developer. These APIs aim to simplify the task of the developer so that they can create apps which work seamlessly.
Final Thoughts
If you are working on a decentralized application developed, then you would come across either of these apps or will be using one of them. In case you are new to this field and are looking for gaining comprehensive knowledge in this field, then you must go for a Certified Ethereum Expert online training program by Blockchain Council. This exhaustive program will help you learn about Ethereum, APIs and allied concepts and at the same time, learn how to use them. In case you want to learn how to use smart contracts on Ethereum based applications, then you must opt for Certified Solidity Developer coursesby Blockchain Council.

Tkeycoin — security, that’s what we’re betting on

Tkeycoin — security, that’s what we’re betting on
Today we will talk about the security of using the Tkeycoin platform and the TKEYSPACE mobile blockchain wallet.
Tkeycoin is a peer-to-peer payment system based on p2p principles and the concept of electronic cash. P2P technology is a fairer means of mutual settlements between users and companies around the world. Modern payment systems are imperfect and may depend on the will of high-ranking officials.
We approached the market from an economic and scientific point of view, borrowing the best from Bitcoin, Ethereum, DASH, and other alternative currencies, mixing modern concepts and building on the global experience of IBM, Microsoft and a number of other companies and research.
The Tkeycoin blockchain is protected by various mechanisms that include advanced cryptographic methods and mathematical models of behavior and decision-making. Blockchain technology prevents duplication or destruction of digital assets.

https://i.redd.it/idy42g9rntx41.gif
In addition to providing security and recording transactions in registers, cryptography also plays a role in ensuring the security of wallets used to store Tkeycoin. Paired public and private keys, which respectively allow users to receive and send payments, are created using asymmetric encryption or public-key cryptography. Public keys are used to generate digital signatures for transactions, which allows you to authenticate ownership of the coins being sent.

https://i.redd.it/95yuky0tntx41.gif
The asymmetric cryptography architecture does not allow anyone other than the owner of the private key to access funds stored in the cryptocurrency wallet, so these funds are kept safe until the owner decides to spend them.
In simple words, in the Tkeycoin peer-to-peer system, only you are the real owner of your money and only You have access to it.
Using tools such as a local Tkeycoin Core wallet or TkeySpace provides you with reliable storage, privacy, and security.
TkeySpace, in turn, adds maximum usability by combining the highest level of security and easy intuitive design.

https://i.redd.it/f0de51vuntx41.gif

How does TKEYSPACE provide security?

TKEYSPACE is one of the first applications that support blockchain in a mobile device and is also the first decentralized application of the TKEY platform.
Its serverless architecture provides the highest level of security for storing all assets in the application. unlike centralized applications that are managed by companies, TkeySpace does not have a Central management authority and operates in accordance with all the principles of peer-to-peer networks.

https://preview.redd.it/4bret8hwntx41.png?width=1253&format=png&auto=webp&s=535c5d879a36eac4ca8c807ee7af1b5fe05e12a9
As we said above, the wallets in the blockchain have a public and private key. Centralized applications usually store users ‘private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
TkeySpace-stores the encrypted key only on the user’s device and in encrypted form. The encrypted key is displayed as a mnemonic phrase (backup phrase), which is very convenient for users. Unlike complex cryptographic ciphers, the phrase is easy to save or write. The backup phrase provides the maximum level of security and thanks to its usual appearance, an attacker is unlikely to ever guess what these words are and what they are for.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If the phrase consists of 12 words, then the number of possible combinations is 2048¹² or 211³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in the strict order as it was presented after generation.
And so that you do not get confused in the definitions and concepts, we will briefly describe simple and clear principles of how it all works. Let’s look briefly at the factors.

Lock Screen

The simplest thing that protects your phone from unauthorized access is Pincode, a snake, a fingerprint or a Face Id login. And it would seem that this is related to TKEYSPACE?
https://i.redd.it/sspjjsgyntx41.gif
  • At a minimum, it is almost impossible to open new mobile devices and pick up a pin code, even in the case of theft, most often the factory settings are reset, which leads to the deletion of all data on the phone, respectively-your funds are safe even for this reason.
  • Even if there was some “craftsman” and somehow managed to change the pin code on your device, the TKEYSPACE app will automatically delete all the keys and backup phrases, the wallet will simply be empty, and the attacker will be left with nothing.
As we can see, even a simple screen lock with a pin or fingerprint protects your data. It’s not as simple a screen lock as you and I might think.
Every platform, whether it’s Android or AppStore, uses specialized key stores. Cryptography, symmetric and asymmetric encryption, keys, and certificates are directly related to this task.
Keys and certificates that are used to protect information must also be securely protected. Android uses Keystore, a certificate and a Keystore, for this purpose.
Keystore is a specialized secret data store that is used by Java applications to encrypt, authenticate, and establish HTTPS connections.
For two-way authentication, the client and server exchange certificates, respectively, and the server and client must have a Keystore with a private/public key pair and a certificate. In other words, the Keystore is used to store keys and certificates that are used to identify the key owner (client or server).
Starting with Android 8, the encryption systems have been upgraded, the system is checked for signs of hacking at startup, and the screen lock allows you to restrict access to the device. Data encryption and the use of keys ensure the security of information when it is stored and transmitted.

https://i.redd.it/2c0b9re1otx41.gif
In the new version of the OS — Android 9 (Pie) — the developers also added support for hardware to protect against unauthorized changes.
Android apps run in an isolated software environment that restricts access to your information to other apps. OS components are also protected, which prevents attackers from exploiting system errors for their purposes.
Android uses both hardware and software to protect users and their data. Therefore, even at the operating system level, there are a lot of security factors. Of course, if you “flash” the phone (change the factory firmware) and enable Root access, this will reduce the security of Your device, but this is more an exception than a rule and such changes are usually introduced by very experienced users.
IOS uses Keychain — a specialized database for storing metadata and confidential information. Using a Keychain is the best practice for storing small pieces of data that are critical to your apps, such as secrets and passwords. In addition to the Keychain, Apple provides a full range of maximum protection for Your device.
And so we will continue,

Passcode in the app

Now we understand that to get access to the tools, an attacker needs to hack the hardware security of the Google and Apple giants to somehow get access to the app, which is impossible.
To increase security and eliminate other risk factors, we have included an access code (secret code) in the app.
You set an additional level of security by enabling a pin code to log in to the app. The access code additionally encrypts all data stored in the app.
Just so you understand — it’s not just numbers that you enter on the screen, this combination affects the ciphers inside the app. When creating a key, a user interface element is called. when the user swipes the screen, the application receives a random set of bytes — thus, all information is additionally covered by a new layer of cryptography.
And as we said above, if you try to disable the pin code, the app will delete all the data, and the attacker will be left with nothing.
As we have already realized, only 2 of these factors provide the maximum level of security for the TKEYSPACE application.
And the most important thing is that the application runs on the blockchain, which guarantees its full Autonomous operation, data immutability, and privacy.
Generation of new addresses, absence of accounts, phone numbers, e-mail and other personal data-provides you with a social level of security, which is a huge advantage in our time.
In a world where security is based on the level of cryptography, attackers try to influence You with the human factor using social engineering, so when you use applications with accounts, phone numbers, you have more risks.
Social engineering is a method of obtaining the necessary access to information based on the characteristics of human psychology.
For example, a copy of a SIM-card has become a new tool for fraudsters, but there is no personal information in TKEYSPACE, so even such groups of fraudsters can’t get access to your funds.

You don’t have to worry about security — it’s already built into the TKEYSPACE system.

A mixed encryption system based on the principles of computational complexity, with the deterministic generation of signatures using elliptic curves, provides absolute security and safety of user funds, and reserve phrases will help you restore funds at any moment.
A mnemonic phrase is 12 or 24 words that are generated using the entropy of random numbers.
If the phrase consists of 12 words, then the number of possible combinations is 2048¹² or 211³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in the strict order as it was presented after generation.
Only you and no one else has access to the phrase. When you get the key, the app has restrictions on the screenshot, and the clipboard is disabled, which protects against malicious software.
It is you, as a user, who sees the phrases, and everything in the device is encrypted, the blockchain architecture protects against hacker attacks, information forgery, and other hacks.
For those who are a bit obsessed with persecution mania, we offer a small lifehack:
Buy several USB drives, connect them to a device that does not have access to the Internet, preferably on a clean operating system, create a text file, write backup phrases there, and encrypt the USB drives with passwords.

https://i.redd.it/shan90o4otx41.gif
Once again, to ensure security and easy recovery, it is enough to record backup phrases once and make several backups. you do not need to resort to an additional encryption method, because we have already done everything for you :)

TKEYSPACE — blockchain in your mobile

TKEYSPACE — blockchain in your mobile

https://preview.redd.it/w8o3bcvjrtx41.png?width=1400&format=png&auto=webp&s=840ac3872156215b30e708920edbef4583190654
Someone says that the blockchain in the phone is marketing. This is possible for most applications, but not for Tkeycoin. Today we will talk about how the blockchain works in the TkeySpace app.
Who else is not in the topic, TkeySpace is a financial application for decentralized and efficient management of various cryptocurrencies, based on a distributed architecture without using a client-server.
In simple words, it is a blockchain in the user’s mobile device that excludes hacking and hacker attacks, and all data is encrypted using modern cryptographic methods.
https://preview.redd.it/8uku6thlrtx41.png?width=1280&format=png&auto=webp&s=e1a610244da53100a5bc6b821ee5c799c6493ac4

Blockchain

Let’s start with the most important thing — the blockchain works on the principles of P2P networks, when there is no central server and each device is both a server and a client, such an organization allows you to maintain the network performance with any number and any combination of available nodes.
For example, there are 12 machines in the network, and anyone can contact anyone. As a client (resource consumer), each of these machines can send requests for the provision of some resources to other machines within this network and receive them. As a server, each machine must process requests from other machines in the network, send what was requested, and perform some auxiliary and administrative functions.
With traditional client-server systems, we can get a completely disabled social network, messenger, or another service, given that we rely on a centralized infrastructure — we have a very specific number of points of failure. If the main data center is damaged due to an earthquake or any other event, access to information will be slowed down or completely disabled.
With a P2P solution, the failure of one network member does not affect the network operation in any way. P2P networks can easily switch to offline mode when the channel is broken — in which it will exist completely independently and without any interaction.
Instead of storing information in a single central point, as traditional recording methods do, multiple copies of the same data are stored in different locations and on different devices on the network, such as computers or mobile devices.

https://i.redd.it/2c4sv7rnrtx41.gif
This means that even if one storage point is damaged or lost, multiple copies remain secure in other locations. Similarly, if one part of the information is changed without the consent of the rightful owners, there are many other copies where the information is correct, which makes the false record invalid.
The information recorded in the blockchain can take any form, whether it is a transfer of money, ownership, transaction, someone’s identity, an agreement between two parties, or even how much electricity a light bulb used.
However, this requires confirmation from multiple devices, such as nodes in the network. Once an agreement, otherwise known as consensus, is reached between these devices to store something on the blockchain — it can’t be challenged, deleted, or changed.
The technology also allows you to perform a truly huge amount of computing in a relatively short time, which even on supercomputers would require, depending on the complexity of the task, many years or even centuries of work. This performance is achieved because a certain global task is divided into a large number of blocks, which are simultaneously performed by hundreds of thousands of devices participating in the project.

P2P messaging and syncing in TkeySpace

TkeySpace is a node of the TKEY network and other supported networks. when you launch the app, your mobile node connects to an extensive network of supported blockchains, syncs with full nodes to validate transactions and incoming information between nodes, so the nodes organize a graph of connections between them.
You can always check the node information in the TkeySpace app in the ⚙ Settings Contact and peer info App Status;

https://preview.redd.it/co1k25kqrtx41.png?width=619&format=png&auto=webp&s=e443a436b11d797b475b00a467cd9609cac66b83
TkeySpace creates initiating connections to servers registered in the blockchain Protocol as the main ones, from these servers it gets the addresses of nodes to which it can join, in turn, the nodes to which the connection occurred share information about other nodes.

https://i.redd.it/m21pw88srtx41.gif
TkeySpace sends network messages to nodes from supported blockchains in the app to get up-to-date data from the network.
The Protocol uses data structures for communication between nodes, such as block propagation over the network, so before network messages are read, nodes check the “magic number”, check the first bytes, and determine the type of data structure. In the blockchain, the “magic number” is the network ID used to filter messages and block traffic from other p2p networks.
Magic numbers are used in computer science, both for files and protocols. They identify the type of file/data structure. A program that receives such a file/data structure can check the magic number and immediately find out the intended type of this file/data structure.
The first message that your node sends is called a Version Message. In response, the node waits for a Verack message to establish a connection between other peers. The exchange of such messages is called a “handshake”.

https://preview.redd.it/b6gh0hitrtx41.png?width=785&format=png&auto=webp&s=0101eaec6469fb53818486fa13da110f6a4a851d
After the “handshake” is set, TkeySpace will start connecting to other nodes in the network to determine the last block at the end of the required blockchain. At this point — nodes request information about blocks they know using GetBlock messages — in response, your node receives an inv (Inventory Message) from another node with the information that it has the information that was requested by the TkeySpace node.
In response to the received message, inv — TkeySpace sends a GetData message containing a list of blocks starting immediately after the last known hash.

https://preview.redd.it/lare5lsurtx41.png?width=768&format=png&auto=webp&s=da8d27110f406f715292b439051ca221fab47f77

Loading and storing blocks

After exchanging messages, the block information is loaded and transactions are uploaded to your node. To avoid storing tons of information and optimize hard disk space and data processing speed, we use RDBMS — PostgreSQL in full nodes (local computer wallet).
In the TkeySpace mobile app, we use SQLite, and validation takes place by uploading block headers through the Merkle Tree, using the bloom filter — this allows you to optimize the storage of your mobile device as much as possible.
The block header includes its hash, the hash of the previous block, transaction hashes, and additional service information.
Block headers in the Tkeycoin network=84 bytes due to the extension of parameters to support nChains, which will soon be launched in “combat” mode. The titles of the Bitcoin block, Dash, Litecoin=80 bytes.

https://preview.redd.it/uvv3qz7wrtx41.png?width=1230&format=png&auto=webp&s=5cf0cd8b6d099268f3d941aac322af05e781193c
And so, let’s continue — application nodes receive information from the blockchain by uploading block headers, all data is synchronized using the Merkle Tree, or rather your node receives and validates information from the Merkle root.
The hash tree was developed in 1979 by Ralph Merkle and named in his honor. The structure of the system has received this name also because it resembles a tree.
The Merkle tree is a complete binary tree with leaf vertexes containing hashes from data blocks, and inner vertexes containing hashes from adding values in child vertexes. The root node of the tree contains a hash from the entire data set, meaning the hash tree is a unidirectional hash function. The Merkle tree is used for the efficient storage of transactions in the cryptocurrency blockchain. It allows you to get a “fingerprint” of all transactions in the block, as well as effectively verify transactions.

https://preview.redd.it/3hmbthpxrtx41.png?width=677&format=png&auto=webp&s=cca3d54c585747e0431c6c4de6eec7ff7e3b2f4d
Hash trees have an advantage over hash chains or hash functions. When using hash trees, it is much less expensive to prove that a certain block of data belongs to a set. Since different blocks are often independent data, such as transactions or parts of files, we are interested in being able to check only one block without recalculating the hashes for the other nodes in the tree.
https://i.redd.it/f7o3dh7zrtx41.gif
The Merkle Tree scheme allows you to check whether the hash value of a particular transaction is included in Merkle Root, without having all the other transactions in the block. So by having the transaction, block header, and Merkle Branch for that transaction requested from the full node, the digital wallet can make sure that the transaction was confirmed in a specific block.

https://i.redd.it/88sz13w0stx41.gif
The Merkle tree, which is used to prove that a transaction is included in a block, is also very well scaled. Because each new “layer” added to the tree doubles the total number of “leaves” it can represent. You don’t need a deep tree to compactly prove transaction inclusion, even among blocks with millions of transactions.

Statistical constants and nChains

To support the Tkeycoin cryptocurrency, the TkeySpace application uses additional statistical constants to prevent serialization of Merkle tree hashes, which provides an additional layer of security.
Also, for Tkeycoin, support for multi-chains (nChains) is already included in the TkeySpace app, which will allow you to use the app in the future with most of the features of the TKEY Protocol, including instant transactions.

The Bloom Filter

An additional level of privacy is provided by the bloom filter — which is a probabilistic data structure that allows you to check whether an element belongs to a set.

https://preview.redd.it/7ejkvi82stx41.png?width=374&format=png&auto=webp&s=ed75cd056949fc3a2bcf48b4d7ea78d3dc6d81f3
The bloom filter looks for whether a particular transaction is linked to Alice, not whether Alice has a specific cryptocurrency. In this way, transactions and received IDs are analyzed through a bloom filter. When “Alice wants to know about transaction X”, an ID is requested for transaction X, which is compared with the filled segments in her bloom filter. If “Yes” is received, the node can get the information and verify the transaction.

HD support

The multi-currency wallet TkeySpace is based on HD (or hierarchical determinism), a privacy-oriented method for generating and managing addresses. Each wallet address is generated from an xPub wallet (or extended public key). The app is completely anonymous — and individual address is generated for each transaction to accept a particular cryptocurrency. Even for low-level programming, using the same address is negative for the system, not to mention your privacy. We recommend that you always use a new address for transactions to ensure the necessary level of privacy and security.
The EXT_PUBLIC_KEY and EXT_SECRET_KEY values for DASH, Bitcoin, and Litecoin are completely identical. Tkeycoin uses its values, as well as other methods for storing transactions and blocks (RDBMS), and of course — nChains.

Secret key

Wallets in the blockchain have public and private keys.
https://preview.redd.it/br9kk8n5stx41.png?width=840&format=png&auto=webp&s=a36e4c619451735469a9cff57654d322467e4fba
Centralized applications usually store users’ private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
A private key is a special combination of characters that provides access to cryptocurrencies stored on the account. Only a person who knows the key can move and spend digital assets.
TkeySpace — stores the encrypted key only on the user’s device and in encrypted form. The encrypted key is displayed as a mnemonic phrase (backup phrase), which is very convenient for users. Unlike complex cryptographic ciphers, the phrase is easy to save or write. A backup keyword provides the maximum level of security.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If a phrase consists of 12 words, then the number of possible combinations is 204⁸¹² or 21¹³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in strict order, as it was presented after generation.

Result

Now we understand that your application TkeySpace is a node of the blockchain that communicates with other nodes using p2p messages, stores block headers and validate information using the Merkle Tree, verifies transactions, filters information using the bloom filter, and operates completely in a decentralized model. The application code contains all the necessary blockchain settings for communicating with the network, the so-called chain parameters.
TkeySpace is a new generation mobile app. A completely new level of security, easy user-friendly interfaces and all the necessary features that are required to work with cryptocurrency.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Crypto Wallet — How to Survive the Winter?

Crypto Wallet — How to Survive the Winter?
by Chao Wang, COO, Bitpie Wallet

https://preview.redd.it/22ykp5ispss41.png?width=372&format=png&auto=webp&s=8578a53632c4f701322c4590649bf64adb7e3300
“Hey Guys, how do you make money?” In the past seven years, users often ask us. In fact, what everyone means is, “If you don’t make money and go broke, will my coins be lost? ” So, we repeat again and again:
“the assets in the non-custodial wallet are kept by the users, as long as the mnemonic phrases are copied and kept in a safe place, the coin will always be yours.”
Similar to most technical tools, generating revenue for crypto wallets is difficult and tortuous. “Do you make money?” A simple ask torture the soul of all wallet teams.

https://preview.redd.it/63dyucwxpss41.jpg?width=310&format=pjpg&auto=webp&s=50c694c4f07226eb088491239f7e8554bf0c388d
For a crypto wallet, generate revenue or not is not only about health of business, but also about safety. A team without a healthy financial situation cannot make continuous and sufficient investment in safety, which will eventually kill them in an industry that changing rapidly every day.

The basic functions of the crypto wallet

The basic functions of the crypto wallet are the management of private keys and the sending and receiving of crypto assets. And no software wallet ever charges their personal users for these basic functions. Free use of wallet is everyone’s basic expectation. Under this expectation, does the blockchain wallet lack value capture capabilities?
Absolutely not.
With the rapid development of the blockchain world, the basic functions have been no longer meet the needs of a certain group of users, thus various advanced functions have emerged. Bitcoin accelerator built into the wallet is a typical scenario, and those people who often send and receive Bitcoins are certainly no strangers to it. There are many such scenarios, such as batch sender, miner fees rescuer as well as some selling points of smart wallets that have just begun to rise. Wallet users are willing to pay for advanced feature that digs deep enough into their pain points, which has been verified in many scenes.
However, there are only a few groups of users who need such advanced functions every day. Crypto is still a small world, the income brought by such functions is not enough, even for a wallet with good market share.

To survive, a crypto wallet has to do more.

Payment needs can be regarded as one of the origins of crypto assets, and this scenario has naturally been followed by many teams. In the past, many teams have made attempts in this field, but the major business model formed by such attempts is to provide payment platforms for merchants and to draw a certain percentage of commission for each purchase received by merchants. In such a scenario, if the crypto wallet is only used as a tool to complete an on-chain transaction, there is no way to charge users. Some wallets have chosen to work with Visa or Master to issue bank cards that can be used easier in the off-chain world and share some revenue as one of the payment channel participants and OTC desk. This could work.

https://preview.redd.it/n2vdibf0qss41.jpg?width=300&format=pjpg&auto=webp&s=0ceeebacb6a4cd2e20eca32182a3addafb53b13a
The Lightning Network is another payment solution native to the crypto community. In the Lightning Network ecosystem, wallets can receive some fees by providing node services.
However, none of those attempts has changed the reality that encrypted assets are only accepted as a payment medium in a very small range. It is a bit difficult to make good money on this. However, with the rapid development of stable coins, a large number of users are rapidly pouring into crypto payment scenarios. These users are directly or indirectly bringing income to the wallet, and the growth rate is amazing.
The production of crypto assets (Mining) is one of the few fields in crypto world that generate income steadily in the past decade. A lot of players are crowded in this field, they have their own strengths, work together, and share the pie. Unfortunately, crypto wallet is not among them. However, with the launch of more and more PoS networks, crypto wallets were introduced into the production process finally, and stood directly at the forefront of the industry chain. There is a new name now: Staking.
More and more PoS network are squeezing into the top 30 of CoinMarketCap. The total output volume from staking can reach tens of billions of dollars per year, a considerable amount of revenue would be generated within crypto wallet by providing services around Staking.
The largest piece of income comes from third party applications. With the improvement of experience and the formation of user habits, both centralized and decentralized third-party services are increasingly accepted by wallet users. As a tool for users to manage assets, such services and wallets have a strong coupling effect.

https://preview.redd.it/1hs48193qss41.jpg?width=280&format=pjpg&auto=webp&s=e5b1c08afcc9ba5a3202fb804519dabe5d0cbf9a
DeFi applications, in particular, are developing rapidly and are bursting with tremendous energy and innovation. As the DeFi application network continues to mature, the asymmetry between centralized and decentralized services will be gradually erased, and the security and other advantages of open finance will be fully reflected. The cross-chain technology is also evolving rapidly, and each major blockchain will soon be connected to form a huge parallel universe. The stable coins and offchain assets projection will act as a wormhole to connect on-chain and off-chain universes. A lot of assets and users are entering the chain through these wormholes, forming a huge cross-border financial network.
The crypto wallet is the entrance of this financial network, and it is also the navigator of people in this complex network.
And DeFi is just a small part of the DApp world. The prosperity of DApp will directly bring huge revenue to the wallet. We have seen it once on the EOS network on winter 2018. Although the prosperity lasted only a few months, leading EOS wallets all received a lot of income, even enough to support them for years. This short period of prosperity is also a precious sample, many imaginary scenes become reality and many problems were exposed. Everyone learned something.
A year and a half have passed since then, we can see major blockchains such as Ethereal and EOS are evolving rapidly, and a lot of team are proposing new ideas and working hard to implement, the ability of DApp teams are rapidly improving as well. I am confident that a greater prosperity of DApp will return in the near future.

https://preview.redd.it/0etz63l5qss41.jpg?width=600&format=pjpg&auto=webp&s=c1d0db9603a54bd2590089121e18c96a76e561cf

The beauty of the new world is becoming clearer and closer.

We will all be the first-generation citizens of it. In this world, the crypto wallet connects people and chain, carbon-based world and silicon-based world. It will not only help everyone’s to manage their cryptocurrency, but also manage their identity, Social insurance, voting rights, financial products, contracts, memberships, lottery tickets, and more things that have not yet been born. Wallet will be widely involved with our daily activities. Even if we use all our imagination, we probably still cannot really imagine where the crypto wallet will evolve into in the future and how important it will be in everyone’s life.

What is DEX Trading and How to Trade Crypto on Trust Wallet

Over the past several months, Trust Wallet has evolved from a crypto wallet app for Ethereum tokens into one of the most robust crypto wallet solutions in the world. Trust Wallet now supports many top cryptocurrencies such as Bitcoin and BNB, as well as many decentralized apps (dApps), making it the only Crypto Wallet app you’ll ever need.
But what if we want to trade the tokens we store on Trust Wallet? Trust Wallet can also be connected to decentralized exchange platforms (DEX), thanks to its multiple features that support the trading of your tokens without your funds leaving your wallet.
But before we delve into what Trust Wallet can do, let’s have a quick recap on what a DEX is and what its advantages are.

What is DEX

A decentralized exchange, or DEX, is an exchange platform where people can trade their assets without needing to create an account on that platform. Instead of using a centralized platform for holding traders’ funds, DEX users can trade directly with each other from their own crypto wallets. On a DEX, every trade is recorded on the blockchain as an individual transaction and all funds come from people’s personal wallets.
It is important to distinguish a DEX from a centralized exchange. The main point of differentiation between the two kinds of crypto exchanges is the custody of funds. With a centralized exchange, like Binance, you create an account, deposit your crypto for trading, and trust that the exchange will keep your tokens secure. DEX’s structure is pretty much different from that.
To further explain the concept of a DEX, let’s describe Binance DEX for example. On Binance DEX, you are not asked to create an account. Instead, you are requested to either create your own digital wallet or connect your existing wallet to the exchange. Either way, Binance DEX will not have any access to your funds. Only you have the means to open and use the wallet, as you will hold the private key, mnemonic phrase, or Keystore file needed to access it.
You can then use the funds that are already in your wallet to start trading on the DEX, as well as to transfer funds to and from other sources.

What makes a DEX different and better compared to other exchanges

Since the dawn of cryptocurrencies, which are created as a decentralized form of sending value across the globe, the first and biggest crypto trading services that emerged are pretty much centralized. There are advantages inherent to centralized exchanges, such as ease and convenience of use, the capability to support margin trading and options trading, higher trading volume and liquidity, and more.
However, trading on centralized exchanges come with their own risks. While top exchanges like Binance have put in place stringent user security and protection measures, safety across the many exchanges that are available may vary from platform to platform. Meanwhile, many cryptocurrency users may be uncomfortable with entrusting funds to centralized exchanges.
DEX platforms like Binance DEX can offer features and advantages that will satisfy the needs of crypto trading users without encountering some of the disadvantages that come with centralized exchanges. Here are some of them:

Trust Wallet and its role in advancing DEX trading

With the ongoing progress of DEX offerings in general, Trust Wallet has been instrumental for this growth. Trust Wallet started as a wallet for Ethereum tokens. Since being bought by Binance in 2018, it has transitioned into a multi-feature wallet with support for the biggest cryptocurrencies in the world.
Trust Wallet’s journey to being the most sophisticated Crypto Wallet app for DEX trading started with the launch of Binance DEX. On the same day that Binance DEX and Binance Chain launched, Trust Wallet launched support for Binance Chain and all the tokens that are created on that blockchain, including its native token BNB.
A few days after the launch of the Binance DEX, Trust Wallet launched support for WalletConnect, allowing users of the crypto wallet app to connect to Binance DEX and start trading on the exchange.
Since then, Trust Wallet has worked on enhancing its support for decentralized exchanges. Just this November, the app launched support for many methods of DEX trading, from the simple token swap to order book-based trading, with support from exchange platforms such as Binance DEX and KyberNetwork.
This is just the beginning of Trust Wallet’s mission to become a one-stop wallet for all your crypto storage and usage needs.

Why Trust Wallet is a great option for DEX trading

Given the wide array of features that Trust Wallet has for storing and using various cryptocurrencies, it has become the crypto wallet of choice for DEX trading. Here are several reasons why we suggest you use Trust Wallet.

How to do DEX trading on Trust Wallet

On Trust Wallet, there are two ways for you to trade crypto in a decentralized way. Both methods are powered by our multi-DEX support through Binance DEX and KyberNetwork technology
Let’s discuss a bit more about the Exchange function of Trust Wallet. When you use Trust Wallet as a DEX via its Exchange feature, you are harnessing the power of the core Binance DEX. This modern, decentralized marketplace for exchanging your digital assets allows you to place limit orders and look at your trade history. This gives you more control over how you trade and more opportunities to pursue the trades that work best for you. The addition of the new order book allows you to precisely tap into the liquidity provided by Binance DEX when placing your orders.
Curious about how to perform DEX trading on our app? Here’s a short video showing how exactly to do so:
