Judgement,
held in public.

Coliseum is an on-chain judging market. Open an arena, pay a fixed submission fee, and let staked votes decide. Every vote and its stated reason is written on-chain, and the finalized verdict is sealed into a soulbound record.

Four rounds,
one verdict.

The order is enforced by contract. Nothing settles early, and nothing settles twice.

I
Create

Open the arena

State the topic, the prize pool and the two deadlines. The factory deploys your arena contract.

II
Submit

Enter the field

Pay the arena's fixed submission fee and register your entry. The contract holds it until the verdict is finalized.

III
Vote

Judgement on record

Each vote costs a fixed stake and carries a written reason, stored on-chain beside the voter's address.

IV
Seal

Verdict finalized

Once voting ends the arena is finalized, the tally is permanent, and a seal is minted to the winner's soulbound record.

A record you cannot sell.

Every verdict you win stamps a seal onto your soulbound token. It is non-transferable by design — a public record of what you have won, not an asset you can sell.
