Since its inception in October 2016, security has been a major focus of NEO, especially our technical team. We have partnered with Red4Sec, a code auditor, and CertiK, a formal verification service platform, both of whom will provide security auditing service for NEO. The former will focus on the code of the NEO platform while the latter on NEO smart contracts using formal verification. Additionally, NEO also has a reward policy for contributors who have identified vulnerabilities. These security enhancement strategies will help maintain the stability of the NEO network in the long run.
