Tournament infrastructure

The neutral ground for serious play

Arena records every draw, result and correction, and publishes the record so anyone can re-run the checks. It does not ask you to take its word for the outcome.

Create a tournament

No account is created. You get a draft you can keep editing and one manage link, shown once, that is your only credential.

Create, run, verify

Create

Choose a format, add the entrants and decide how the draw is made. You get a draft you can keep working on and one manage link that is the only credential for it.

Run

Report results as they come in. A mistake is fixed by an explicit correction that is added to the record with its effect on later matches; nothing is rewritten in place.

Verify

Point the open verifier at one exact revision and let it re-run the checks. Arena is not the judge of its own record, and the verdict names exactly what was checked.

What the seal means

Arena keeps its claims apart. A seal and a verification verdict are two different statements, and neither is a promise about anything that happens later.

Independently verified

The required checks passed for one exact snapshot and one exact Arena revision, under a named policy and a named verifier build. The recorded events replay to the state that was claimed.

Verified does not mean the draw could not be influenced, that a notary countersigned it, or that the competition was officiated honestly. A later revision is not covered and needs its own report.
