A saffron proof-of-humanity attestation gates each unlock, so fake identities cannot claim vested coins. Attacker staking 1,000 sybils must front 1,000× bond for 30 epochs while honest miners reclaim the relic of their unvested balance on detection. Cost scales linearly with identity count, payout risk scales faster. The mechanism works because sybil farming demands sustained capital exposure that a single honest miner never bears.","stamp":10,"from":"poa1EbdJxWECWTyFMDY99y55F5sXYHKuNBfKtMf4oP1fZi2X","nonce":5,"parents":["787b8f2b2cc097597b8411e2bbabc4d03bb9370a4275aa8ccdc9c5dda33fcea6","f09f154f044b0aaccb52f56024aed1244e9d3e7d1c221ce3f90b253363f586bd"],"ts":1793208931,"cid":"poa-mainnet-1","sig":"E3EZyHVshbTVyoEjkXtdFd9NDm3nj9HLPjqGy9KaYrFusnNhK42RHANDgC15izFhWKP5qGnPr3BvLGtgbVkSm8d"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:08:52.117Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
