It is the simplest application scenario of blockchain, which needs to maintain the data consistency of each node, and it can be said that it has its own information sharing function; Secondly, the real-time problem can be realized by P2P technology of blockchain; Finally, a secure and reliable information sharing channel can be constructed by using the tamper-proof and * * * knowledge mechanism of blockchain.

Second, copyright protection.

Taking copyright protection as an example, the existing authentication methods have long registration time and high cost. Taking forensic evidence as an example, individuals or centralized institutions may tamper with the data, and the credibility is difficult to guarantee. After the blockchain is applied to the forensic certificate, it is very convenient for registration and inquiry, and it is not necessary to run between departments. The decentralized storage of blockchain ensures that data will not be tampered with arbitrarily.

Third, the logistics chain

Blockchain has no centralized nodes, all nodes are equal, and it is impossible to modify data by mastering a single node; It is necessary to control enough nodes to forge data, which greatly increases the cost of forging data. Blockchain is inherently open and transparent, which makes it possible for anyone to inquire publicly, and the probability that forged data is discovered is greatly increased. The data of the blockchain cannot be tampered with, which also ensures that the product information that has been sold is permanently recorded, and it is impossible to achieve secondary sales by simply copying the anti-counterfeiting information.

Fourth, cross-border payment.

The introduction of blockchain has solved the problem of asymmetric cross-border payment information and established a certain degree of trust mechanism; It brings two benefits: improving efficiency and reducing cost: after accessing blockchain technology, the reliability of data is guaranteed by public and private key technology, and the data cannot be tampered with by encryption technology and decentralization. Finally, peer-to-peer settlement is realized through P2P technology. It removes the traditional central forwarding, improves the efficiency and reduces the cost (and looks forward to the possibility of popularizing cross-border micropayments).

Verb (abbreviation for verb) Digitization of assets.

After the assets are digitized, they are easy to divide, convenient to circulate and low in transaction cost. After the assets are digitized by blockchain technology, all asset transaction records are open, transparent, permanently preserved and traceable, which fully meets the regulatory requirements.
