Blockchain Security Ecology

Smart contract ecology is gradually enriched, and breakthroughs are increasing

The number of smart contract users and the number of blockchain projects are increasing year by year, and more and more security incidents have occurred. According to incomplete statistics, the economic losses caused each year exceed 10 billion yuan, and the trend is increasing year by year. The maximum amount involved in a single case can reach up to One hundred million U.S. dollars.

Public chain security issues have become a new focus

The security vulnerabilities of the public chain have a great impact on the ecology of the entire chain. The economic losses caused by security incidents may be fatal and difficult to recover. The highly complex architecture of the public chain also makes the discovery of security risks more difficult.

Public Chain Security Solutions

Conduct source code audits and overall security testing for public chains, and identify possible security risks through deployment of the test environment and combining the source code.
