1Sat Ordinal ticketing · physical and virtual events
Secure at the gate. Valuable after the show.
TicketMint is building ticketing in which each ticket is a single satoshi on the BSV blockchain: signed by the organiser, verified by a key signature instead of a barcode, and redeemed once at check-in. After the show it remains a collectible, tied to its original on-chain artwork.
In development. Not yet open for public ticket sales — see exactly what works today.
How it works
Three checks stand between a fake and the door.
A barcode is a picture, and pictures copy. A TicketMint ticket is an on-chain asset held by a key, so a gate can ask questions that a copy cannot answer.
Issued by the organiser
Every ticket names its issuer and carries the issuer's signature, and it is minted in a public transaction. A lookalike without a valid issuer signature fails verification.
Bound to a key
At the door, the gate shows a one-time challenge and the holder's wallet signs it. A screenshot or a forwarded QR code has no key, so it cannot answer.
Redeemed once
Check-in spends the ticket into a redeemed state. The network accepts that spend only once, and a gate turns away a ticket that has already been redeemed.
Plain answers
What the blockchain guarantees, and what it leaves to the gate.
“On the blockchain” is often used to mean more than it does. Here is the line between what the network enforces for everyone and what the issuer and the venue remain responsible for.
Enforced by the network
- No double spend. Each transaction output can be spent only once. Check-in is such a spend, so no issuer, venue or platform, including us, can make the network accept a second redemption of the same ticket.
- A permanent, public origin. The transaction that created the ticket, and the artwork inscribed in it, stay on the public chain. A ticket that changes hands is traced back to that origin.
- Verification without permission. Anyone with a public explorer or indexer can check where a ticket came from and whether it has been spent, without an account and without asking TicketMint.
Checked by the gate and the issuer
- Admission. The chain records that a ticket was redeemed. It is the gate that checks the holder's signature and the ticket's status before letting someone in.
- How many tickets exist. The issuer decides how many to mint. The chain does not cap supply; it makes each mint visible.
- Offline doors. When venue connectivity drops, gates verify against a list synced before doors open and settle on-chain afterwards. Two disconnected gates can briefly both admit the same ticket; syncing closes that window and flags the collision.
Who it is for
Simple for fans. Useful for the people running the night.
For fans
- A ticket you can check. Its origin and status are public, so a ticket can be verified as genuine and unused before money changes hands.
- Nothing to learn. The goal is “log in, here is your ticket” — the wallet is created for you and the blockchain stays out of the way.
- Something to keep. A redeemed ticket is designed to stay with you as a collectible, linked to its original artwork, as a record that you were there.
For organisers and artists
- Your signature on every ticket. Tickets are issued under your identity, not ours, so authenticity does not depend on a reseller's word.
- Gates built for real venues. The gate protocol covers both online and offline scanning, with duplicates detected across gates.
- One system for doors and streams. The same ticket and the same signed check are designed to open a venue door, a stream or a VIP room.
Events
One kind of ticket for physical, virtual and hybrid events.
Every ticket is the same primitive, a one-satoshi ordinal with artwork and event details, configured for the event it belongs to.
Concerts and club nights
General admission or reserved, with a collectible that outlasts the night.
Festivals
Several tiers and several gates, including gates that lose their connection.
Streams and virtual events
The signed check that opens a door is designed to unlock a stream as well. In development.
VIP and backstage
Tiered access from the same ticket, so one pass can cover the venue and the room behind it.
See for yourself
A real ticket, on mainnet, that you can check without us.
We minted this demonstration ticket on 8 July 2026. It is one satoshi, it has not been spent, and every fact below comes from the public chain. It is held under a plain single-key lock; the ticket contract described below has not yet been used on mainnet.

Where we are · October 2026
What works today, and what comes next.
TicketMint is in development and is not yet selling tickets to the public. We would rather show the line than blur it.
Built and tested
- A ticket minted on BSV mainnet with its artwork inscribed on-chain (the one shown above).
- The check-in protocol: issuer signature, key-signed one-time challenge and single redemption, tested against copied, replayed and counterfeit tickets on a local model of the chain.
- Online and offline gates with duplicate detection across gates and later settlement, tested against a local model of the chain.
- A demonstration storefront, checkout and wallet, without payments or minting at checkout. The wallet displays the mainnet sample ticket decoded live from the chain.
- A first ticket policy contract, run in script interpreters only and never used on mainnet.
In development
- Signing in a real holder wallet. In today's demonstration the ticket key is created and kept in the holder's browser and signs the check-in there. That is a stand-in, with no backup and no device security.
- Check-in and resale settled on mainnet. Today these are built and previewed but not broadcast.
- Resale rules, such as price caps and a share for the organiser, written into the ticket's contract. A first version exists and its scripts pass interpreter tests; it has not been shown end to end.
- Cancellation and recovery rules in the ticket contract. The first design is under review and is being revised.
- Stream access for virtual events.
- The post-show collectible view in the holder's wallet.
- Payments, and minting a ticket at checkout.
