Background
All third-party electronic evidence storage platforms which can obtain judicial approval nowadays utilize the hash encryption technology. However, in the evidence of block chain evidence, hash encryption is only one of the security measures, and in addition, there are two core underlying technologies of consensus mechanism and decentralized storage, the two technologies are the most essential difference between common electronic evidence and block chain evidence.
The block chain technology is an information system architecture based on a distributed system and taking public shared accounts as a core. The block chain technology can directly incorporate the hash value abstract which is locally generated and used as the source file evidence into a certain block of the block chain, the block fixedly stores the source file evidence through a hash function, and the hash value abstract of the former block is also incorporated into the latter block when the latter block is newly generated, so that the block chain is formed after delay. In the process, if a certain data is tampered, all block data on the chain is to be changed, under the guarantee of a consensus mechanism that the whole chain is tightly buckled, the change of electronic evidence caused by the fact that a certain hash function is broken can be completely avoided, and decentralized distributed storage is also the core advantage of the block chain.
