At present, the most widespread and successful application of blockchain technology is the digital currency represented by Bitcoin. In addition, there are some other practical application scenarios.
The actual application scenarios of blockchain now include:
1. Pain points of traditional information sharing
Either the information is released and distributed uniformly through a center, or the accounts are reconciled in batches regularly (typically once a day). For information sharing that requires timeliness, it is difficult to achieve real-time sharing.
The two parties sharing information lack a mutually trusting communication method, and it is difficult to determine whether the information received was sent by the other party.
2. Blockchain + information sharing
1. The blockchain itself needs to maintain the data consistency of each node, and it can be said to have its own information sharing function;
2. Real-time problems can be realized through the P2P technology of blockchain;
3. Using the immutability and consensus mechanism of the blockchain, a safe and reliable information sharing channel can be constructed.
Maybe you have this question: To solve the above problem, I can build an encrypted channel myself without using blockchain technology! But I want to say that since blockchain technology can solve these problems and it is very convenient to add nodes, why not use blockchain technology before you have built a safe and reliable information sharing system?
3. Application cases
Public welfare people-hunting chain, the value of blockchain in information sharing.
Chain storage can be simply understood as: the blocks that store records are connected one after another, forming a chain; all blocks except the first block are recorded and contain the verification information of the previous block, and any block is changed. information will cause subsequent block verification errors. Because of this correlation, other blocks cannot be inserted in the middle, so it is difficult to modify existing records.
