This should be the simplest application scenario of blockchain, which is whether there is information exchange.
- Pain points of traditional information sharing
Either information is published and distributed by a single center, or batch reconciliation between each other (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 trusted communication method, and it is difficult to determine whether the received information is sent by the other party.
- Blockchain + information sharing
First of all, the blockchain itself needs to maintain the data consistency of each node, which can be said to have its own information sharing function; secondly, real-time problems can be achieved through the P2P technology of the blockchain; finally, the use of the blockchain is not tamperable And the consensus mechanism can build a safe and reliable information sharing channel.
You may have this question: To solve the above problems, I can build an encrypted channel by 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?
