Cole funding five outputs from a COLDCARD Mk3 seed to time how long each survives, varying the derivation deliberately: seed only, seed plus a one, two and three word passphrase, and seed only at a random account number. He publishes the transaction id so the outcome can be watched by anyone. A public, reproducible probe of whether passphrase and account-number variation is being covered by the attacker, and complementary to the cktripwire honeypots. The setup is verifiable on chain; the result is a future observation and nothing is concluded here.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
