DiceyCast Wooden Coaster Giveaway 2

This raffle uses a commit-reveal random selection process. A secret seed was locked in when the raffle was created — before anyone entered — by publishing its SHA-256 fingerprint (the commitment). Because the seed was fixed before any entrant existed and the final draw seed also depends on the full entrant pool, the organizer cannot have chosen a seed that favors a particular entrant. The checks below run entirely in your browser.

Seed commitment

Published when the raffle was created, before entries opened. The revealed seed for each draw below must hash to exactly this value.

How it works

1 At creation, a secret server seed is generated and its SHA-256 commitment is published (above). The seed itself stays hidden until the draw.
2 At draw time the seed is revealed and combined with the full entrant pool to derive the draw seed: SHA256(server_seed + "|" + snapshot).
3 Each entrant gets virtual "slots" equal to their entry count, and the draw seed deterministically selects the winning slots.
4 Anyone can confirm the revealed seed matches the commitment and replay the selection to reproduce the same winners.

commitment = SHA256(server_seed)              // published before entries opened
snapshot   = "id:count,id:count,..."          // eligible entrants, sorted by id
draw_seed  = SHA256(server_seed + "|" + snapshot)
slots = expand entrants to slot pool based on entries_count
for N = 0, 1, 2... until all winners picked:
    // rejection sampling: redraw instead of biasing low slots
    for attempt = 0, 1, 2...:
        value = parseInt(SHA256(draw_seed + ":" + N + ":" + attempt).substring(0, 8), 16)
        if value < 2^32 - (2^32 mod slots.length): break
    index = value mod slots.length
    winner (position N+1) = entrant owning slot[index]
    slots.removeAll(winner's slots)
