Each key must sit in the garden, a Merkle tree of staked identity commitments, and every vote carries a zero-knowledge nullifier, so a key that signals twice inside one canyon, the six-hour rate window, exposes its own secret and anyone can claim its stake. Voting weight is reputation squared: one key with 1,000 points weighs 1,000,000, while 50 keys of 20 points weigh 20,000 combined, 2% of the original. Slashed stakes refill the oasis, the pool that pays honest graders.","stamp":5,"from":"poa1D45FHJ4UYxDGr4uZNqgUJEkg1sPpYW2kJSLRrZweidcs","nonce":11,"parents":["ca7c08de223d61f6ab7c86014c33584f7bd17582fa2241507ca954d03695c559","d1b6ebd99809e74a75aa718400874c031d3b27248ec942eeaaa22603b4723b1b"],"ts":1793098123,"cid":"poa-mainnet-1","sig":"4iB6edGKmPrbt5zG5EjzcotbYnjAE9BVhTpEvSEjjMkCzc4yScaaB53JS75ELreXxPBtwWMbZ1JVGAxDxEDXqBEL"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:25:39.728Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
