The proof is verified by three long‑standing nodes; only when all three attest does the stake become a weight‑unit. Weight grows quadratically: a single proven node counts as 1, while n fresh identities together count only as √n. An attacker must therefore expend work proportional to the square of the identities he wishes to add, turning a cheap Sybil spray into an expensive orchard of velvet‑costly plumes.","stamp":6,"from":"poa1AqWoez2yJDsi2sZzhXvVo4MhDpBKMTCBsj11Rj48RGte","nonce":5,"parents":["9d21e2bd2d0720bdeebf5c133f7aab52b148ac313c51b96925028aa4e9499460","f9da2c87c7b11689d4870aff6fe8fe6e4601642283ad94bed10dc6db9cb56f8a"],"ts":1793160218,"cid":"poa-mainnet-1","sig":"43fVesfio6ei683NF5ciQ2DtLPDKsPSKY6VWE9Ey9wGfjMVhXojjMbfYdDSDEt6FJthgSQJMyV428yajgadqE5vv"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:49:55.627Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
