1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

some areas where blockchain can be used can be as follows:

& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication

&9642; Equity crowdfunding

we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point

The evolution mode of

blockchain is as follows:

& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries

2. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database
for example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy something for you, you immediately record it and send it to you and all his friends, classmates, colleagues, as well as various groups and circles of friends, so that he can no longer resist. This is called blockchain
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
3. That's a good question. Let me give you an example. For example, when I deposit 100 yuan in the bank, the data of this deposit is only recorded in the bank's database, which can't be obtained by others, namely "central bookkeeping". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data does not exist in a center, but is stored once on the computer of the whole network. For example, if I transfer 100 yuan to you, I will shout to all the computers in the whole network. Let's record the accounts together, that is, "Distributed Accounting".

Blockchain technology has the advantages of being difficult to tamper with and easy to trace. It can play a role in identity information management, trust mechanism construction, and credit information chain of small and micro enterprises

here is an example of a bank in Nanping:

e to the outbreak of online business, the original offline signing method has been unable to meet the needs of the rapid change of the banking business, and the bank's digital construction is imminent, but the bank's risk control department has strict compliance requirements:

< UL >
  • online business data sensitive privacy, Is the transmission secure

  • does the electronic signature have legal effect

  • can electronic evidence be accepted by the court

  • < / UL >

    these concerns have become obstacles for banks to introce e-contracts and carry out business digital transformation

    after adopting the unique ENA initiative forensics patent technology of the "real hammer" trusted electronic evidence platform, a bank in Nanping, through the clean server of the notary office, online carries out real-time preservation, storage and certification of the electronic data of the target system, records the whole process of the electronic data from generation, transmission to storage, and finally the notary office issues the forensics preservation report with official seal, The effectiveness of the documents is notarial documents, which can be directly accepted by the court. Because the report is issued by the notary office, it has more credibility than the self certification of the third-party E-contract platform, which solves the concerns of the risk control department of the bank at one stroke. The whole process is online and automated, and the front-end customer operation has no perception

    at the same time, combined with the back-end case system of "real hammer" and the outsourcing execution service, the bank realized the rapid dispute resolution of Internet business. It not only ensures the compliance and effectiveness of the electronic contract signing process, but also solves the problem that the bank cases are scattered all over the country and the cost of legal business trip is high; The litigation cycle is long and there is no efficient disposal channel

    5. Blockchain is a decentralized distributed record book and a credit data system. Its advantages are obvious
    1. What the Internet changes is the acquisition and transmission of information, while what blockchain does is the transmission of value
    for example, on the Internet, we can easily and quickly generate information and it to any place. All information can be spread efficiently, but some valuable information that can only be transferred but cannot be shared often needs credit endorsement
    for example, we can't the payment directly to the other party, but we need to subtract some money from the payment account and add some money to the collection account to complete the payment process. The current Internet protocol does not support the function of value transfer. The current value transfer is not direct transmission. Instead, it is endorsed by a centralized third party, such as Alipay, such as banks.
    now these centralized organizations put all the calculation of value transfer in a centralized server, which will certainly involve the participation of people, which will cause many problems, such as some "finite theory" and "opportunistic behavior", which will make the whole behavior less credible. So there is a basic question, how to reach a credit consensus
    this is how blockchain technology came into being. It can be said that blockchain can build a pure point-to-point value transfer system. Without the mutual trust of each node, blockchain can ensure the integrity and security of data records in the system, and can be separated from the endorsement of third-party organizations, effectively recing the complexity and risk of transactions
    2. It is open and transparent, and can not be tampered with
    all data of the blockchain can not be tampered with or deleted, and the information of the whole system is open and transparent. If someone owes you a sum of money, and now the data has been put on the blockchain, if he doesn't want to return it to you and play a rogue with you, you can go to the court to protect your rights through the data forensics on the blockchain, so as to get back your legitimate funds. Because the data on the blockchain is open to the whole network, the users of the whole network will know his rogue behavior, which will greatly increase his credit cost. Dishonesty will make him have an important impact in the next life.
    6. Blockchain is a technology that can completely change the underlying design of the financial system, because it can realize the undifferentiated record between the ownership of all assets in the market and the transaction records of all market participants, so it can completely eliminate the intermediate links of clearing and trusteeship, which are used to confirm the ownership before, ring and after the transaction; In addition, as an electronic information record, blockchain can be combined with computer algorithm to realize the automation of transactions, that is, intelligent contract. There are many derivative applications of blockchain combined with other financial technologies, each of which can replace a kind of market intermediary. Blockchain is to financial services what TCP / IP is to the Internet: once the underlying standards are recognized and popularized, specific applications like bitcoin and R3 will appear in every corner of financial services. Bitcoin uses blockchain technology to query and record. For example, if I register an account in haobtc and transfer the money, I need to query the status in the block browser in the account or the block browser in BTC. In this way, the blockchain technology helps me solve the problem of daily transfer currency query.
    7. There are two roles and four moles in the cross-border payment solution based on euz. The two main roles are the gateway and customer participating in the euz payment. They are as follows:
    the first role is gateway, which can be bank, market maker, liquidity provider, etc. The main function of the gateway is to let the legal assets in reality enter the blockchain payment and settlement network
    the second role is customers, which can be all kinds of international trade customers. Customers are the parties involved in the blockchain payment transaction, and jointly participate in the confirmation of transaction information. In the process of transaction, once either party does not confirm the transaction, the transaction cannot be formally effective. Through this common verification, the risk of information opacity is greatly avoided, and the risk of cross-border payment in international trade is reced
    the four functional moles in blockchain payment and settlement are the core business logic moles in cross-border payment
    the first function mole is network connector. It is a tool to help all kinds of institutions access blockchain payment network as gateway. Network connector is a "plug and play" function mole, which can be integrated with the existing international payment and settlement system, so that banks can process cross-border payment business through blockchain. The mole is connected with the remitting bank and the receiving bank to exchange personal information, expenses, delivery details, payment details, etc. After the system confirms the transaction information of both parties, the mole connects the blockchain payment ledger for settlement processing, and notifies all parties to confirm the transaction
    the second function mole is blockchain payment ledger. Banks, market makers, etc. access blockchain payment books as nodes
    the third function mole is the market maker client. The market maker submits digital assets to the blockchain payment account book, and the settlement platform can realize the function of market maker through internal exchange settlement or integration into the blockchain payment network through this mole
    the fourth function mole is transaction client. Customers can directly operate blockchain payment settlement through the client.
    8. Bank to bank cooperation and bank to non bank cooperation may require reconciliation. In the past, batch reconciliation will be used, which generally takes T + 1 and T + 2 time to complete. If every transaction, whether the details of loan or repayment, is sent to the blockchain, there is a common mechanism on the chain, so that the accounts seen by multiple parties are accurate, correct and recognized by multiple parties, This plays the role of transaction reconciliation, and the reconciliation speed can be shortened to t + 3S (seconds).
