Responsible disclosures
Responsible disclosures were occasions when someone discovered a vulnerability in Bitcoin-related software and reported it to developers, affected users, and the public in a way that helped minimize harm.
This page lists occasions when Optech reported on a responsible disclosure and makes a best-effort attempt to cite the names of the people who made the disclosure. There are many other responsible disclosures not listed here, including those which have not been publicized yet.
When it’s unclear whether a disclosure was made responsibly, Optech will do its best to judge the situation based on the information readily available to us. Entries to this page may be added or removed at a later time based on new details.
