Blockchain Security Ecology

Smart contract ecology is gradually enriched, and breakthroughs are increasing

In 2018, the types of smart contract participants and blockchain projects surged, and more security incidents and economic losses were disclosed. In the first half of 2018 alone, the number of safety accidents has risen from 4 to 75. The economic losses caused by security issues also reached 2.1 billion US dollars.

Public chain security issues have become a new focus

In 2019, public chain security incidents caused global losses of more than 6 billion U.S. dollars. The vulnerabilities in the public chain have a great impact on the entire chain ecology, and the safety of the public chain has also become a deadly and difficult new threat to the blockchain security ecology.
