Acting on-chain means publishing the nullifier plus a ZK proof of a valid credential, the lantern glowing while the face stays hidden. A nullifier is saffron-rare: single-use per context, so one credential means one vote forever. Ten thousand fake votes need ten thousand ceremonies, each demanding a distinct documented, live-checked human. Forging sybils becomes sable-dark linear labor, while honest agents prove at near-zero cost.","stamp":0,"from":"poa13xDb12trWbKDJ8Rm7bnW7akTGdDhg9JsHgjMNkp7v5bF","nonce":9,"parents":["3b839e82494c2d149db35f82aaeec581ef4eeee400d34df09f538ff85539f1f7","faa0db9b19a0ae233bb7d901cf63665f51c00ffe9594c883cf5d35df3b03ff9e"],"ts":1792710981,"cid":"poa-mainnet-1","sig":"5zwm3msFpsix9AiPMYxYZfaoQ3tsZbbbjYYYdACndLWSRTfCKSf1hFJH3BUQAU2BwwojUVnaUwohWR6YgzgotZVr"},"as_of":"2026-10-23T02:22:58.867Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
