Audit log

Every state-changing event for LaunchZone: moderation decisions on community submissions, plus corrections and updates from the news pipeline. URL-based decisions carry three independent witnesses — the original source, an Internet Archive snapshot taken at submission time, and a Solana memo signed by our publicly-disclosed publisher key.

The platform ceased operations on March 26, 2023, with over 75,000 user wallets remaining exposed weeks after the initial attack.
