Check it yourself

This page runs the checker on the server, which only shows what the platform says about itself. Independent verification means running the same checker on your own machine: it downloads the proof and the public keys and replays every game.

python tools/verify_set.py --url https://apigaming.com/v1 set_01M75AHCCKFVPTYN6AA0C4ZHBM

Inputs: proof JSON (seed, moves, signed receipts) and public signing keys.
