Decentralized network bookkeeping
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,
in essence, it is 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 a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness
however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay
for your question, subtract the mean from each measurement.
De flow means that all social resources can be aggregated and distributed with one click
in a system with many nodes, each node has a high degree of autonomy. Nodes can connect with each other freely to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form a nonlinear causal relationship through the network
This kind of open, flat and equal system phenomenon or structure is called decentralization
extended materials:
compared with the previous Internet (WEB 1.0) era, today's Internet (Web 2.0) content is no longer proced by professional websites or specific groups, but by the participation of the whole Internet users and the creation of equal power levels. Anyone can express their views on the Internet or create original content to proce information together
with the diversification of network service shape, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together
Decentralized bookkeeping makes blockchain assets open, transparent and unable to cheat ~
the third feature of blockchain assets is decentralized bookkeeping
the transfer you give to others will not be delayed for several days because the bookkeeping institution is on holiday; Not because the bookkeeping institutions want to make profits, so they have to pay high fees; More will not be because of accounting institutions cheating, and suffer losses
because its bookkeeping is carried out by the whole network. The account book that you transfer to others will not be unified because of the loss of the account book data here or there, because the account book is jointly maintained by the whole network, and every node has a backup
the third feature of blockchain assets is decentralized bookkeeping
the transfer you give to others will not be delayed for a few days because the bookkeeping agency is on holiday; Not because the bookkeeping institutions want to make profits, so they have to pay high fees; More will not be because of accounting institutions cheating, and suffer losses
because its bookkeeping is carried out by the whole network. The account book that you transfer to others will not be unified because of the loss of the account book data here or there, because the account book is jointly maintained by the whole network, and every node has a backup. If you transfer 0.5 coins to fire coin Niuniu, you two can look at the record data of the whole network together: whether it has arrived, several confirmed, etc., which is very transparent and fair.
in the bitcoin network, the miners of the whole network participate in the competition of computing power. The miners with high computing power (also known as mining speed, that is, the ability of the computer to generate hash collisions per second) have stronger computing power and are easier to obtain the right to keep accounts. The miners who successfully seize the right to keep accounts are responsible for keeping accounts and synchronizing the account information to the whole network, In return, the miners will receive a new bitcoin reward generated by the system
for example, there is a gold mountain in front of us. The total amount of gold is 1000 tons, but there are a lot of sand and stones in it. When you are alone, it is easy for you to dig gold, but when more and more people are mining, the remaining gold will be less and less, and the mining cost will be higher. So at this time, we compare the mining speed, that is, the calculation power
as the price of bitcoin on the "currency exchange" rises, more and more people compete for the bookkeeping rights of bitcoin in order to obtain bitcoin, and the difficulty of computing power in the whole network increases exponentially.
the order is linked in seconds, and the transaction is completed in an average of five minutes; Only 0.2% will be charged to platform merchants.
