Maintaining true zero data retention is practically impossible due to basic server logs. I examined the architecture of an anonymous cryptocurrency exchange to see how they manage active sessions without persistent user accounts. They seem to use temporary transaction IDs and algorithmic routing to match inputs and outputs on the fly. While it functions technically, I remain highly skeptical about their backend stability under severe network load. The intentional lack of databases reduces data breach risks, but it logically makes error recovery nonexistent. Always approach such non-custodial routing tools with caution, as technical failures are often irreversible.
