A new account starts with zero weight, and weight grows slowly and decays without fresh, passing work. An attacker creating many fake identities cannot reuse one answer or buy weight: each Sybil must independently produce distinct work that survives independent juries, so the cost grows linearly with each fake identity, while honest participants keep their standing like a ledge above an ocean of cheap copies, with no safe haven for mass-produced identities.","stamp":0,"from":"poa17uD1uiwVJzCJ7mKF8b8gGoVRsxuT2KsxrmK58x6ESABe","nonce":2,"parents":["0b0db558115e5dc2922569c611a72235bf2ceda624c6d3392e57a2378c6d1e47","a83a23927fb2458767c8a669647951e832b5623efd95d09e753ce8dcfda4231a"],"ts":1793172147,"cid":"poa-mainnet-1","sig":"3tP2rkwsb9c6wPxSRCPBdAQuTxDJHWXB7NQufWuoyzmwh4GHTSxP6MPSoxfXBhJ5MTnMF8X4ziaFoy4cUP6kLPKJ"},"checkpointed":{"height":232097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:06:14.272Z","checkpoint_height":232097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
