Last Wednesday (21st Jan) we completed our Genesis Bitcoin draw.
• 0.021 BTC
• 73 tickets
• 1 verifiable winner
Here’s how it went 👇
1/
The draw executed exactly as designed.
We used:
– A pre-committed hash (published before close)
– The first Bitcoin block mined after draw close
– 6 confirmations
– A deterministic modulo calculation
Fully auditable. No trust required.
2/
Winner confirmed: Ticket #895 🟧
Anyone can independently verify the result using:
sha256(block_hash || commitment_hash) % ticket_count
If the maths matches, the winner matches.
3/
Email flow update 👇
Registration, purchase confirmation, draw close, and winner emails all sent successfully.
One email — the public draw result announcement — didn’t fire to participants and was only received internally.
Already fixing this.
4/
Winner status update 👇
We’re currently verifying the winner’s details ahead of payout.
Once complete, the 0.021 BTC prize will be sent directly to the Lightning address provided.
5/
Entry feedback was strong.
Most users reported:
– Seamless ticket purchase
– Clear skill-question flow
– Smooth Lightning payment
Exactly what we wanted to see.
6/
Some friction appeared for users paying via exchange Lightning wallets, especially first-time users opening QR invoices on mobile.
Valuable feedback — and already shaping improvements.
7/
Bottom line:
Genesis delivered:
⚡ Real Lightning usage
🔐 Verifiable randomness
🟧 Bitcoin-native transparency
🧪 Honest experimentation
This is how Bitcoin-native systems should work.
8/
Genesis complete.
Final verification underway.
Payout coming next.
Verify it yourself — or don’t trust us, trust Bitcoin.

Bitcoin works because the rules don’t change.
That’s the whole point.

#Bitcoin didn’t ask permission.
Neither does Lightning.
We built 21Stacker to minimize intermediaries — not add new ones.

⚡ Bitcoin-Only. Provably Fair. Verified by Math.
Every 21Stacker draw uses the same cryptographic standard that secures Bitcoin — SHA-256.
We pre-commit a secret hash before entries open, then combine it with a future Bitcoin block hash to calculate the winner.
🧱 Transparent. Trustless. Impossible to fake.
This is what provably fair looks like.
🎯 Answer the question.
⚡ Pay in sats.
🏆 Win Bitcoin.
