According to incomplete statistics on the market, during 2011-2018, the losses caused by security incidents in block chains amounted to $3.1 billion. It is worth noting that since 2017, the loss amount of block chain security incidents has shown an exponential upward trend. Since the development of 2018 alone, its loss has reached $1.9 billion. Security has become the core of the development of block chain. In addition to security issues, the industry has not yet reached a consensus on block chain cryptography, signature standards, underlying technical framework, industry applications, evaluation and authentication. Interaction and operability are missing, and fragmentation is developing seriously.
