What does blockchain work on? How do you view the principle of blockchain? In fact, most people may not understand the principle of blockchain very well, after all, we are not professionals, but when it comes to bitcoin, people know relatively more, especially now that the price of Bitcoin is so high, so more and more people know.
The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, which makes the transaction based on cryptography rather than trust, so that any agreed parties can directly carry out the payment transaction without the participation of a third party.
Technically, a block is a data structure that records transactions, reflecting the flow of money in a transaction. The blocks of transactions that have been made in the system are linked together to form a main chain, and all nodes that participate in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, including the private key of both sides of the transaction, the number of transactions, digital signature of electronic money, etc. The hash hash formed by the previous block is used to join the blocks to achieve the order of past transactions; Random number is the core of transaction, all miner nodes compete to calculate the answer of random number, the node that gets the answer fastest generates a new block, and broadcast to all nodes for update, thus completing a transaction.
Blockchain technology is actually known through bitcoin at the beginning, and the blockchain technology based on bitcoin is also known gradually since the price of bitcoin has been and gradually speculation. So what do you think of the blockchain principle?
Actually block chain has been gradually applied to every aspect of our lives, and block chain is also were no longer a new technology, and is now on its technology and P2P network technology combined together after more able to ensure the data security and independence, but nonetheless these technologies are based on the technique of block chain principle.
On block chain principle: block chain principle is actually the father of the COINS in the hearing about the study published in the previous nine pages in the white of the advanced electronic system, in 2009, in the hearing in a small server is located in the Finnish unearthed the first block of the currency, also known as block creation, it also represents the currency was born.
