What is a blockchain snapshot (blockchain photography)

What is blockchain snapshot? According to official news, blockchain snapshot is a kind of protocol implementation based on Ethereum. That is, encrypt transaction data through smart contracts and upload it to the public chain for verification. In blockchain networks, each transfer requires the user to submit a proof document (such as a hash value), which can then be applied to various applications to verify its authenticity. If a node does not comply with the requirements or refuses to provide them with verification information, the operation cannot be performed. The emergence of blockchain technology enables it to solve one of the problems that many blockchain applications currently face: low efficiency and performance issues

According to Cointelgraph, recently at the “China Blockchain Technology Development Forum and 2019 China Blockchain Industrial Ecology Conference”, Wang Jianhua, senior engineer of the Institute of Computing of the Chinese Academy of Sciences, said, “We are building a distributed photo network based on Ethereum. This is a new mode of storage, transmission and management.” At the same time, he also pointed out that “shooting by using the blockchain requires a lot of power. The consensus mechanism on the blockchain makes these devices more resistant to attacks; and can prevent tampering or malicious use”, he added. The irreversible nature of blockchain technology allows any photographer to encrypt and verify image data, without worrying about theft
