⑴ What types of API interfaces do current blockchain API tool projects have on BTC, ETH and EOS public chains?
Based on a blockchain I am currently using Let’s take an example of an API tool.
I accidentally discovered BCTools before, which can quickly and easily perform ready-to-use testing and verification of BTC and EOS blockchain APIs. At the same time, these API interface test networks and mainnets can be verified on BcTools; the original poster If you are interested, you can go to http://bctools.io to use it.
At present, the APIs on BCTools seem to have the following types:
⑵ How is blockchain technology used in the banking industry?
< p>The biggest feature of blockchain technology is decentralization, and this feature will reduce a lot of costs for the banking industry.First of all, decentralization means that intermediaries are no longer needed to establish a trust mechanism between banking systems, saving intermediary costs.
Secondly, the development of digital currency will make it possible to realize real-time digital transactions in banks. For example, in bill transactions, bank bill transactions have always relied on a third party to realize the transfer of valuable certificates. Even electronic bill transactions require interactive authentication through information from the central bank's ECDS system. Blockchain technology can realize point-to-point transfer of value and no longer requires centralized system control. This not only speeds up the speed of ticket transfer, but more importantly, it can reduce errors caused by human factors and reduce processes. Naturally, it will reduce the bank's demand for personnel and save the bank's labor costs.
Finally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by central clearing, which is inefficient. Settlement through blockchain technology will greatly improve the efficiency of banks.
Blockchain technology also plays a major role in banks’ cross-border payment services. Today, when global trade is highly developed, cross-border payments are becoming more and more frequent, and banks often act as third-party services in cross-border trade, such as electronic transfers, asset custody, etc. However, cross-border payments generally take about 2 days to arrive, which is very inefficient and reduces the utilization of funds in transit. In blockchain technology, both parties of cross-border payments can be completed in a point-to-point manner, achieving round-the-clock payment and real-time arrival, thereby speeding up clearing and settlement, thereby improving the efficiency of bank processing business.
Another feature of blockchain technology is de-risking. Banks can build their own blockchain, which can ensure that bank customers’ transaction information and transaction records are true and valid and will not be compromised. Without any tampering, the bank can effectively identify the customer's information, understand all aspects of the customer's situation, identify the customer's abnormal transactions, prevent being deceived by the customer, thereby reducing the bank's supervision costs.
⑶ Who can help me introduce what blockchain technology is?What's going on
The so-called blockchain technology, also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records . What it wants to do is to enable all parties involved to establish a trusting relationship at the technical level.
Explained in layman’s terms: If the database is assumed to be a ledger, reading and writing the database can be regarded as a bookkeeping behavior. The principle of blockchain technology is to find the fastest and best bookkeeping within a period of time. This person will keep accounts, and then send this page of information to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.
Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain.
What is the core meaning of blockchain? My understanding is that the core meaning of blockchain is to establish data credit among participants and create a unilateral ecosystem under clear regulations through unilateral confrontation. This is a system that jointly guarantees complete opportunities. This kind of establishment can end the problems before the blockchain. Before the blockchain, it was impossible to achieve new sharing when data was shared. Even if it was targeted, it would only be for you. With an interface, the blockchain allows participants to share credit.

Implement the core development values of Bitbox and actively improve all aspects of the current blockchain industry
⑸ Characteristics of blockchain
1. Decentralization
The so-called decentralization means that because the blockchain uses distributed computing and storage, there is no centralized hardware Or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.
2. Openness
The so-called openness means that the blockchain system is open. In addition to encrypting the private information of the transaction parties, the blockchain data is open to everyone. Public, anyone can query blockchain data through the public interface and develop related applications. The information of the entire system is highly transparent.
3. Autonomy
The autonomy feature of blockchain is based on specifications and protocols. The blockchain adopts consensus-based specifications and protocols (such as open and transparent algorithms), so that all nodes in the system can freely and securely exchange data in a trustless environment, changing trust in "people" to machines. trust, no human intervention can work.
4. Information cannot be tampered
Because of this, the stability and reliability of blockchain data are very high. Blockchain technology has fundamentally changed the centralized credit creation method, using mathematical principles rather than centralized credit institutions. To establish credit at low cost, birth certificates, real estate certificates, marriage certificates, etc. can be notarized on the blockchain, with a global central node, becoming something that is trusted by the world.
5. Anonymity
The so-called anonymity means that the exchange between nodes follows a fixed algorithm. The data interaction does not require trust, and the counterparty does not need to disclose its identity. The other party has trust in you, which is conducive to the accumulation of credit.

Explanation of terms:
Blockchain token
< br /> A new business model created based on blockchain technology, and token is the token of each project. We collectively call it 'token'. Tokens are generated as the project progresses and develops
and are circulated with landing applications. Value (this value depends on the consensus of everyone)
The blockchain is a bit like a huge, global and decentralized accounting book.
It uses To record how much currency one person sends to another person, and to track the balances of all accounts.
It is performed by thousands of people around the world who have special computers (we also call them miners) Recorded and maintained.
Blocks in the blockchain are composed of many transaction records. These transactions are operated from wallets such as Imtoken, MetaMask, Exos, Mist, Geth, Parity and other similar operation interfaces. Send it out
2. Airdrop
Each project will airdrop a certain proportion of tokens as a benefit for the start of community construction. In order to allow more future users to participate, airdrops are It is the most important part of the commercial application of blockchain (you can understand it as the previous Internet projects allowed everyone to take taxis, eat, etc. for free)
3. Wallet
Wallets are divided into ' lightWallets, hardware wallets, Bitcoin wallets, Ethereum wallets, cold wallets, etc.
Blockchain technology solves different industry pain points in different fields, so the value generated is also very different
/>
For example: Bitcoin has solved the problem of trust, so now its value is 50,000 yuan a piece
Ethereum has solved the problem of smart contracts, so it is now worth 4,000 yuan a piece. A
Ripple solves the problem of cross-border payments, so it currently ranks third in market value
4. Pain points solved by the wallet
Traditional banks
When you register an account at a bank or exchange, these institutions will create a new account for you in their internal systems. The bank will closely track your personal information and record your account password. Balances, transaction records and complete control of your funds. The bank will charge account management and service fees while providing services to you, such as helping you recover stolen credit card purchases. The bank allows you to use prepayment by check or debit card. payment methods, as well as check your balance online, reset your password, and replace your lost debit card. When you use a bank or exchange account to trade, the transaction amount and transfer address may be affected by these Institutional restrictions, and there is also an audit process. These restrictions will also charge you additional handling fees.
Virtual Currency Wallet
When you create a When you create an account, it actually just generates a pair of cryptographic digital strings: the private key and the public key (address) of your account. The entire process of generating these keys occurs in the browser of your local computer or mobile phone. Internally, the wallet file will never forward, receive or save your private key, password or any account information. The wallet file will never charge any handling fees. Simply put, you just use this operation interface to directly interact with the blockchain network Interact. If you provide your public key (address) to others, then the other party can send you tokens. If you provide your private key to others, then the other party has complete control of your account and funds.
5. Wallet security
Please actively pay attention to the security of your account private key and password. Your private key may sometimes be stored in a mnemonic phrase, keystore file, or UTC file. , JSON files, wallet files, etc. Please remember that if you accidentally lose your private key or password, no one can recover them. If you enter your private key on a phishing website, they will steal it all your assetsKim. Don’t trust or click on web links you see in email, Slack, Reddit, Twitter, etc. Make it a good habit to manually enter the address to open the website, and don’t open the website through a link in the email or other channels. Change your Make backup copies of private keys or passwords. It is best not to save them on your computer, handwrite or print them on paper. Save backups of private keys or passwords separately in a secure offline environment, if they are kept together with your computer. Then a fire or flood can easily destroy them all. Never store private keys in online network disks, photo albums with cloud synchronization and other online environments. If you really value your digital currency, then you You should buy a hardware wallet. Your assets deserve to be protected with more professional equipment.

⑺ USDT payment interface development plan
Want to make a blockchain payment interface? Then you first need to understand the following points:
1. Have a certain basic understanding of the blockchain industry, so that you can also know what coins to use, where the coins can be traded, and other related knowledge question.
2. Blockchain acceptor. Blockchain payment requires the use of some acceptors for account rotation and fund diversion, so it is also necessary to find some people from the blockchain industry who are engaged in platform acceptance.
3. Team. Thinking of a blockchain platform also requires personnel to operate and maintain it, so corresponding people need to be arranged to do it. It is more important to have a complete team.
The blockchain payment system has two versions: user and merchant.
What is the difference between the blockchain payment system and the traditional payment system?
Traditional payment process: user - remitting institution - bank - intermediary bank - intermediary bank - bank - collecting institution - user/merchant.
Blockchain currency payment system process: user—(pay BTC/ETH and other currencies)—blockchain payment—(settlement USDT/CNY/USD)—user/merchant.
What is an acceptor?
Acceptor: A team, enterprise or individual that holds coins or assets. It mainly plays the role of acceptor in the blockchain acceptance payment platform, that is, the payee handles deposits and withdrawals, which is the entire A core role in payment platforms. Of course, there are also many platforms that also act as platform acceptors themselves.
How does blockchain payment solve industry pain points?
1. The new model of "coins go through channels and money goes offline", the platform and merchants do not have direct contact with legal tender
2. Acceptance merchantsAs the payee, can funds be diverted to solve the deposit problem?
3. The acceptor adopts account polling, which can realize instant payment and T+0 settlement
4. Virtual currency can be used as a payment method to expand market business such as overseas markets.
5. The virtual currency funds can be checked on the blockchain, and the transaction information can be traced, safe and reliable
6. It is safer for payment platforms and merchants to collect coins, and there are no frozen accounts. Problems
Users: It is used by ordinary consumers who have a certain understanding of virtual currency. In addition to managing virtual currency, through cooperation with online or offline merchants, they can directly pay on the blockchain. The system makes the payment.
Merchant: The merchant version mainly provides settlement management for merchants who join the operation platform. The merchant can be an online mall or an offline physical store.
USTD payment system, virtual currency blockchain acceptor payment system development, clearing system settlement system, blockchain payment system development, OTC acceptor payment system development, virtual currency trading platform development (coin currency Matchmaking, C2C, OTC, contracts, etc.), enterprise-level blockchain application basic BAAS platform, financial transaction system and other high-end software product development, Yuanzhongrui continuously activates product potential and value by digging deep into industry pain points.
