Every week, in public

Results and proof

Each week we publish the total number of entries, the site the winner chose, the amount they won, and everything needed to re-derive the result from scratch. Nothing here asks you to take our word for it.

How the winner is picked

Committed before, decided after

Before the week opens we generate a random 32-byte server seed and publish its SHA-256 hash. We cannot change the seed afterwards without that published hash failing to match.
When the week closes we take the hash of the first Bitcoin block mined at or after Monday 00:00 UTC. Nobody — us included — can know it in advance, so we cannot go looking for a seed that picks a winner we like.
The two together select the entry:index = HMAC‑SHA256(serverSeed, "week:blockHash") mod entryCountindexing into the week's entries ordered by the time they were received.
Afterwards we publish the seed, the block height and hash, the entry count, and a digest of the ordered entry list — so the entry set cannot be quietly edited after the fact either.

Check any week yourself:

import hmac, hashlib
i = int(hmac.new(server_seed.encode(),
                 f"{week}:{block_hash}".encode(),
                 hashlib.sha256).hexdigest(), 16) % total_entries
# i is the published winner index

Confirm the block is real at any explorer, and confirm the seed hashes to the commitment published before that week began.

The first draw has not run. When it does, it appears here within minutes and stays here permanently — including the weeks with small entry counts.

If you win

We email the address on your entry within 3 days, and you have 7 days to reply before the prize is forfeited and redrawn. Entries created automatically from a signup may not have an email address attached — in that case the winning username is announced here and the same 7-day claim window applies. Full detail is in the giveaway terms.
