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.
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.
No public tournaments yet
Nothing is listed right now. Tournaments set to unlisted or private are never listed either, so this says nothing about how many exist.
