1. blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more
In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency
bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently
extended data:
type of blockchain
1, public blockchain
any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world
2, Alliance (instry) blockchain
instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain
3, private blockchain
only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes
2. Satoshi Nakamoto, who calls himself Japanese American, is the creator of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin". In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins.
3. Traditional transactions on the Internet need to rely on trusted third-party institutions to process electronic payment information, and both parties trust the third-party institutions However, the third-party intervention also has many disadvantages:< Br > - high transaction cost (a certain handling charge)< Br > - Privacy exposure (the third party needs to provide the information of both parties in order to verify the information)< Br > -... < br > imagine that if the third-party organization is removed and the two parties trade directly, how can the transaction take effect? The emergence of blockchain technology is to solve this problem. Blockchain is based on the principle of cryptography rather than trust mechanism, which makes the two parties reach an agreement to trade directly and publish it to all witnesses.

6. Covering the sky, alien evil king, special forces in the city, perfect world, legend of Lingtian,
7. I normally use the algorithmic cat aggregate payment, which is very convenient to use, especially the bookkeeping function, which saves a lot of time. I can check the accounts at any time and make it clear at a glance (qiaohu)
8. Blockchain is at the end of 2008. In the paper bitcoin: a peer-to-peer e-cash system
9. The earliest designer of China's
virtual currency blockchain is Mr. Zhang Ronghuan. You can go online: Zhang Ronghuan's gene of digital economy indicates that bitcoin blockchain mode is the gene of digital economy in the top-level design of ecological civilization.
