Blockchain main wallet and sub-wallet

①How many kinds of blockchain wallets are there

There are many kinds of wallets in the market, which can be divided into desktop wallets, mobile wallets, online wallets, hardware wallets and paper wallets according to the platform; Connection can be divided into cold wallet and hot wallet; according to the degree of autonomy and the way of interaction with the network, it can be divided into full node wallet, SPV light wallet and third-party wallet.

③ What is a blockchain wallet

In order to understand a blockchain wallet, you must first understand several core concepts.
1. Wallet address: Similar to bank card number, a person can have multiple bank cards, and similarly he can have multiple wallet addresses. A wallet address can only correspond to one private key.
2. Wallet identification code: similar to the customer ID (name) of a bank card.
3. Public key and private key: The holder of the private key is the holder of the currency in the bank card. The private key can calculate the public key, the public key can generate a wallet address through a series of digital signatures, and the data encrypted with the private key can be decrypted with the public key, and vice versa.
I am relatively familiar with this piece, and I also have an idea to develop a blockchain wallet, after all, it is a high-tech wallet. I learned about a development company called Xuanling Technology on the Internet before, and I also consulted the people there, and I feel that it is quite professional. I hope it can help you~

④ What is the function of the blockchain wallet? Can you explain it?

The essence of the blockchain wallet is a private key, which is a A random hash value string, with the private key, you have the right to use the wallet. According to the private key storage method, it can be divided into: cold wallet and hot wallet
Cold wallet refers to the wallet that the network cannot access your private key, and it is usually recorded in a notebook, although the risk of hackers stealing the private key is avoided. , but may also be lost.
A hot wallet is a wallet that can be purchased on the Internet to access your private key. Hot wallets are often in the form of online wallets, which are not easy to lose, but are also risky.

⑤ The main functions of the blockchain wallet

Usually a wallet will include the following functions: Support the creation of wallet accounts by generating mnemonics, Keystore files, and private keys. Supports exporting wallet account mnemonics, private keys, and Keystore files. Support multiple wallet account management, account balance inquiry and transfer function (QR code scanning support). Support ERC20 tokens (balance display, transfer, token price display) Support fiat currency (USD and RMB) to display currency price in real time. The historical transaction list shows that the display form of creating an account blockchain wallet is divided into address and account number, which we collectively refer to as account number here; the account number of different blockchains is different, and the degree may also be different. The cost of creating accounts on different blockchains is also different. For example, the accounts of Ethereum and Bitcoin are free, but the accounts of EOS need to be created at a certain cost. Since the creation of a blockchain account is a complex process, wallets exist to help users simplify these processes. Generally, in the process of creating an account, the wallet will guide the user to back up the private key or mnemonic, and then perform secondary verification to ensure that the private key or mnemonic backed up by the user is accurate. On the blockchain that needs to create an account through payment, wallets generally help users to complete the payment process using traditional payment tools to reduce the difficulty of users. Digital asset management Digital assets mainly refer to various tokens (Tokens) on the blockchain. The existence of wallets greatly facilitates users to manage their own assets, including transfers, collections, viewing asset details, transaction details, etc. The function is similar to the bank’s APP, you can see what assets you currently have, how much you have, and transfer your assets. It should be noted that assets between different blockchains cannot be transferred directly, that is, you cannot transfer BTC (Bitcoin) to an Ethereum account, nor can you transfer ETH (Ethereum) to a Bitcoin account. Digital asset transactions The digital asset transactions currently supported by the wallet mainly include the following three situations: currency exchange, exchange transaction, and OTC transaction. Currency exchange Through currency exchange, assets on different blockchains can be exchanged, for example, you can directly exchange the BTC (Bitcoin) you own into EOS. General transactions can only be traded in the form of a basic pair, and then the final destination currency is traded through the basic pair. For example, if I want to change from A to C, it needs to be realized through intermediary B, A -> B, B -> C; and currency exchange simplifies this process, directly exchanging A into C to participate in ecological construction.�In the previous part of the public chain design, users in the ecosystem are encouraged to actively participate in the construction of the public chain ecosystem. The main forms are node voting, referendum, staking, etc. Node voting takes EOS as an example. EOS has a total of 21 super nodes. After staking the EOS in their hands, users can vote for up to 30 nodes. The purpose of voting is to allow users to choose the ones who can contribute to ecological development and contribute their own strength. nodes, thereby promoting the stable development of the ecology. Referendum Referendum refers to the blockchain ecology, participants can initiate proposals that they think are beneficial to the community, and the entire blockchain token holders vote. When the number of votes exceeds a certain standard, the proposal automatically takes effect. The referendum method is conducive to the active participation of community users in blockchain governance. The Chinese name of StakingStaking is equity pledge. At present, some public chains adopt the form of Staking to encourage token holders to pledge Token, and thus generate stable nodes. For example, COSMOS pledge can enable the pledger to obtain a certain annualized income (settled in pledge currency), which is similar to investing a current financial management in the bank. Experience Dapp Application DApp is the abbreviation of Decentralized Application, which is translated as decentralized application, which refers to the application development with the blockchain as the bottom layer. At present, DApps are mainly concentrated on Ethereum and blockchains such as EOS, TRON, and IOST. The relationship between DApp and the underlying platform is like the relationship between APP and iOS and Android systems. For example, the DApp of EOS cannot run on the bottom layer of ETH, just as the APP of Android cannot run on the iOS system. You can experience the decentralized finance MakerDAO on ETH in the wallet, experience the start of the competition in EOSRacing? Win EOS rewards, or conduct mining and financial management in the Liebi mining pool on IOST. At present, some large-scale games exist in the form of third-party independent APPs. When you experience DApps in the form of APPs, you also need a wallet as a medium for login and transaction authorization. Asset appreciation wallets naturally have financial attributes. At present, the wallet has integrated a variety of financial tools and functions including mining pools, wealth management, mining, and project investment, which can meet the needs of users for asset appreciation. Mining pool: At present, there are mainly two ways of mining: POW mining and POS mining. POW (Proof of Work) is computing power mining, and it is also familiar to us such as BTC (Bitcoin), ETH (Ethereum) mining; POS (Proof of Stake) mining is to imitate POW computing power mining, coin holders can Stake tokens to validator nodes to get rewards and dividends. At present, the mining pool of the wallet is basically based on POS mining. Some wallets also support the purchase of cloud computing power for BTC (Bitcoin) mining. Wealth management: The wealth management products in the wallet are very similar to traditional wealth management products, the only difference is the settlement method. An estimated rate of return is usually agreed. After the user purchases the wealth management product with Token, it will be settled regularly according to the agreed settlement date, and it can be retrieved or renewed when it expires. Mining: Mining is mainly based on DApp mining. Some DApp mining machine products are collected in the wallet. Using the mining machine, you can easily and quickly obtain the Token you want to mine. Taking the recently popular EIDOS as an example, the EIDOS mining machine can help users realize automatic transfer and mining. These mined Tokens can be sold on exchanges to gain profits. Project investment: Take HOO Labs of Hoo Wallet as an example, you can use USDT to support the project, and get the project’s Token according to a certain proportion of the number of supported USDT.

⑥ What is the role of the blockchain wallet

Cold wallet refers to the bitcoin storage technology developed by an information technology company that provides secure storage solutions for blockchain digital assets. The cold wallet integrates the functions of digital currency storage, multiple transaction password settings, publishing the latest market and information, and providing hard fork solutions, and uses QR code communication to keep the private key from accessing the Internet, which can effectively prevent hackers from stealing.

⑦ Which blockchain wallet is easier to use

The blockchain industry has developed so far, and the underlying technology and technology are very mature. Therefore, the differences between the blockchain wallets of various companies will not be very large.

How to use it is easier to use, in fact, it mainly depends on the optimization of security, supported currencies and experience. Essentially, blockchain wallets fall into two categories: hot wallets and cold wallets (hardware wallets).

1. Hot wallets can be equivalent to software wallets to a certain extent.

The advantage is that it is simple to operate, easy to manage, and more suitable for entry-level users.

But the disadvantages are also obvious. Every transaction needs to be verified online, and data security cannot be guaranteed.

The well-known hot wallets in the market such as imToken, Maizi wallet, etc.

2, cold wallets generally refer to hardware wallets.

The private key of the cold wallet will never touch the network, and the private key will never enter the network. A hardware wallet is a dedicated electronic device for storing encrypted assets. Its function is to store the private key in an internal chip. The private key never leaves the device, so it is very safe. Therefore, general hardware wallets are cold wallets.

Advantage: The private key is generated through the mnemonic and is permanently retainedInside the hardware wallet, it will not leak out, so the security is high.

Insufficient: It is not very convenient to use, it doesn’t matter if you receive it, you only need to provide an address. If so, connect the device to a computer or mobile phone. So it is not as convenient to use as a hot wallet.

The primary consideration when choosing to use a hardware wallet is security, so in general, if you want to truly protect your assets, you must prepare a hardware wallet.

At present, there is no hardware wallet with complete coverage of currencies in the market, but there is a blockchain wallet called TJ Wallet, which is the first safe and reliable Filecoin-supported software and hardware ecological wallet in China. Triple hardware encryption, supports mainstream currencies such as BTC, ETH, Filecoin, etc., and supports the expansion of all currencies, while taking into account convenience and security, it is a good blockchain wallet. The topic owner can pay attention to the following~

⑧ Which blockchain wallet is the best to use and the most secure

I always use TokenPocket, the security is OK, it supports Bitcoin, Ethereum, eos, There are eleven bottom layers such as iost and Binance, and the DApp in it should be the most abundant in the wallet. I can solve many problems with this wallet
