Security & Transparency

Key never leaves the server
When a collision solves the puzzle, the private key is written only to FOUND_KEY.txt on the pool server. Workers receive {"type":"solved"} with no key data. The server operator (pool owner) is the only one who can access the key.
Workers submit DPs only
Workers send Distinguished Points — random EC curve coordinates with no cryptographic value alone. No worker ever sees, computes, or transmits the private key. DPs are verified server-side before any collision check.
Open source & auditable
The pool server, worker client, and collision logic are all open source. The SOTA v2 Kangaroo kernel uses RetiredCoder's GPLv3-licensed RCKangaroo. You can inspect every line of the solve logic.
Collision verification
Every collision candidate is verified by computing candidate × G and checking it equals the target pubkey before declaring a solve. Spurious DP matches are silently discarded.
