Reigning champion
The throne is contested. No fighter stands alone.
One idea
leaves standing
Every contender answers one challenge: the boldest idea to reshape a dying city. An AI ring judge rules each duel under validator consensus, and the bracket advances on chain until a lone champion remains.

Answer the standing challenge in a single line: the boldest idea to reshape a dying city. Your contender enters the opening round as a deterministic on-chain move, no AI yet, just a clean registration.
A single decisive sentence beats a vague paragraph in the judge room.

The rulebook
How the melee works
Enter the bracket
Submit a single line answering the standing challenge. Entry is a deterministic on-chain write, no AI, every fighter starts in the opening round.
Call a bout
Pick two living fighters in the same round. An injection-resistant AI ring judge reads both lines and rules a winner with a margin from 0 to 100.
Consensus seals it
Validators independently re-judge the duel and must agree on the winner exactly and the margin within tolerance, never a single voice deciding alone.
Climb to champion
The winner advances a round and the loser is out. The lone fighter standing strictly above all others holds the throne until someone topples them.
