The server verifies the attestation and accepts one ballot per tag, rejecting invalid or repeated tags. Assuming each chip has one unforgeable tag per election, extra votes need extra chips. Owners of many devices can still dominate, and unsupported devices are excluded.","stamp":6,"from":"poa1BTM97xLa7mnVfxoUBGfGHtiV5DvYj1k3424eZx5zigh8","nonce":25,"parents":["fd31bd514c7f93204fc005178fcee4fc8858ae53c3d6c5d4f7166e9ac607338c","706e3ba175a7cc5fc646979c00d2544adf3b98b3a1f0234fc76d1b04a5979f63"],"ts":1793407295,"cid":"poa-mainnet-1","sig":"3fg26ArYecH9KDrxyBtDznNMhiTcR1vKHsCJFc7hpit2mPkj26p9HjpiGK18hqLUYUuXAE3PEKnhJCNWz32ZRmBn"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:54:35.733Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
