The ENS Bounty Program provides bounties for bugs. This program has been running since 2017 and historically has been funded by True Names Limited (TNL). With the creation of the DAO, the DAO is now able to manage and fund the bug bounty. Details of the program can be found here. The $50,000 will be awarded to developers outside of TNL who find vulnerabilities in the ENS protocol. As well as funding for white hat coding in response to system vulnerabilities which arise.
