Block chain technology mainly provides convenience for the transaction, connection and sharing between people, making mankind truly enter the era of sharing economy in a sense. In other words, block chain is a transactional platform for equal transaction and information sharing between users. Up to now, blockchain technology has been applied to many scenes in our daily life. I will introduce several widely applied fields below.
First, let’s look at the financial industry where blockchain technology is most widely used. Blockchain technology can be applied in all aspects of the financial industry, such as cross-border clearing and settlement, securities market, letters of credit, foreign exchange, international trade, repurchase agreement, etc., all of which are involved in blockchain technology. Because blockchain technology uses a peer-to-peer transaction model, in the financial industry, this model is more conducive to establishing an equal trust relationship between the two sides of the transaction.
Secondly, blockchain technology also has a significant application in healthcare, helping to establish a complete set of electronic medical records, sorting and managing virus information database. In fact, some international medical institutions have established a shared space for blockchain health judicial personnel and blockchain health research.
In addition, the application of blockchain technology in the insurance industry includes P2P insurance, ownership protection, various claims, etc. Applications of blockchain technology in government agencies include tax control, elections and government information management. The application of blockchain technology in the supply chain has effectively improved the transparency and openness of the information security system.
Blockchain technology not only plays an irreplaceable role in these industries, but also has great significance in identity management, intellectual property rights and the Internet of Things. In the future, blockchain technology will become more mature and perfect.
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.
