It is a distributed database that records transactions in a chronological order, creating a digital ledger that is tamper-proof and transparent. The technology uses cryptography to secure the data and establish a trustless ecosystem where transactions can be carried out without the need for a central authority.","a":"Immutable data: Each block contains the hash value of the previous block, forming a chain structure. Once the data in a block is changed, it will cause the hash value of  the subsequent blocks to change, rendering the entire chain invalid. Therefore, to tamper with the data on a blockchain, one must simultaneously tamper with all related blocks and ensure that the hash values of all blocks remain consistent."}]}],"pr":"052cdcb89fa3d96b10e6347b21ca5b5065a28c080f18a2d4c4476a49f22681b1"}
