Bookkeeping methods in blockchain

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 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.

2. 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".

3. Blockchain technology is also known as distributed ledger. Generally speaking, if we assume that the database is an ledger, reading and writing the database can be regarded as a kind of bookkeeping behavior. The principle of blockchain technology is to find the fastest and best person for bookkeeping in a period of time, and then send this page of information of the ledger to everyone else in the whole system. This is equivalent to changing all the records in the database and sending them to every other node in the whole network, which can not only ensure the data security, but also ensure the authenticity of the data, so as to enhance the social credit.

4. For the benefits, jinwowo feels that the biggest benefit is to obtain great security. First of all, there is a central ledger, so it cannot be destroyed. As like as two peas, each node is only part of the system, and each node has the same rights. Destroying some nodes has no effect on the system at all. Secondly, you can't cheat, because unless you can control most people's computers in the system to make changes, the system will refer to the opinions of most people to decide what is the real result. As a result, it will find that it is totally meaningless to modify your own account book (because others don't admit it). Secondly, since there is no centralized intermediary, making everything run automatically through preset proceres can not only greatly rece costs, but also improve efficiency. Since everyone has the same account book, it can ensure that the process of account book recording is open and transparent.

5. Blockchain technology will not affect efficiency and waste computing power. The key is to see how to innovate in a mode and how to use blockchain technology efficiently to achieve the effect of the mode
blockchain is essentially an encryption algorithm, which is based on the principle of hash 256 bit algorithm to achieve information security; The application of modern information will become more and more global and universal. Besides the basic requirements of anti tampering, anti repudiation and trustworthiness, the protection of privacy needs to be strengthened. The blockchain technology is proced because of the development of modern cryptography. The cryptography used today is the result of cryptography 20 years ago, Therefore, in order to apply the blockchain technology to more participation scenarios, especially in the Internet economy, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed
as long as we use blockchain to make innovations in accounting methods based on our own mode, it will not affect efficiency and waste computing power, but will shorten the time and improve efficiency.

6. On the nodes of the blockchain, everyone can access the P2P network for accounting, but no one can tamper with the information in the database, so it is a public accounting book. The technology of recing risk is being introced into the six degree chain

7.

Distributed accounting technology is a database distributed on multiple nodes or computing devices. Each node can and save a ledger, and each node can update independently. Its feature is that the ledger is not maintained by any central organization, and the update of the ledger is built and recorded by each node independently

The

node can vote on these updates to ensure that they are in line with the majority opinion. This kind of voting is also called consensus, and consensus is automatically reached through the algorithm. Once a consensus is reached, the distributed ledger will update itself, and the latest agreed version of the ledger will be saved on each node

distributed accounting technology solves the problem of trust cost, which is less dependent on banks, government and Justice Department, and the data is all on nodes. At the same time, it also solves the problems of consumer rights, financial integrity and transaction speed

extended data:

distributed ledger is a kind of database shared, copied and synchronized among network members. Distributed ledgers record transactions between network participants, such as the exchange of assets or data. This shared ledger eliminates the time and expense of mediating different ledgers

distributed ledger (also known as shared ledger, or distributed classification technology) is a replication consensus, sharing and synchronizing digital data geographically distributed in multiple websites, countries, or institutions. There is no central administrator or centralized data storage.

a point-to-point network is required, and consensus algorithms are used to ensure replication at nodes. A form of distributed classification design, blockchain system, can be public or private

but not all distributed accounts must use chain blocks to provide security and effectively realize distributed consensus: blockchain is just a type of data structure, which is considered as a distributed ledger. In 2016, many banks tested the balance of payments account

the participants in the network restrict and negotiate the updating of the records in the account book according to the consensus principle. There is no intermediate third-party arbitration institutions (such as financial institutions or clearing houses) involved. Each record in the distributed Ledger has a time stamp and a unique password signature, which makes the ledger an auditable history of all transactions in the network

8. You can't cheat, because unless you can control most people's computers in the system to be modified, the system will refer to the opinions of most people to decide what is the real result, and it will find that it is totally meaningless to modify your own account book
