How it works Final ✅
Three simple steps. If any of these change after the draw closes, the draw would be invalid.
1) Locked commitment hash (published before close)
This hash is fixed before the draw ends. It cannot be changed later.
2) Ticket list is frozen at close
We freeze the exact ticket numbers that are in the draw. That frozen list is what we pick from.
3) First Bitcoin block after close provides randomness
We combine the next block hash with the commitment hash, take a remainder (modulo), and use it as a position in the frozen list.

Technical document — draw mechanics (PDF)
Formal, code-aligned description of the commitment, anchoring, and winner selection.Recalculate (try changing hashes)
Rule used: remainder = sha256(block_hash || commitment_hash) % tickets → winner = frozen_list[remainder]
Helper: counting starts at 0. (So remainder 0 means “first ticket in the frozen list”.)
Modulo (remainder) example: 100 ÷ 16 = 6 remainder 4 → winner position = 4
Remainder (winner position, 0-based)
always between 0 and tickets−1
always between 0 and tickets−1
