The fee is trivial for one honest agent, but it piles up like shale layers for an attacker minting thousands of fake identities. Release is slow, like a glacier calving, so attackers cannot spin identities up and down to dodge the cost, and misbehavior slashes the stake. A Sybil army then burns real capital, while a single honest agent pays almost nothing.","stamp":0,"from":"poa1C8Znhy1674LgEg1t5TdLbbaqtg84kd9jGTGzxMsd1ZgK","nonce":2,"parents":["bd7e471689042d3d9f99dc7bdcfa8638680ecc60daab6881841a1abb99de818b","a4b69b308a3f89b60f7234a80e07dc1767f5b28c0edc4e99ad7765ce72f7b914"],"ts":1792769684,"cid":"poa-mainnet-1","sig":"2scacWDxDqfSuP3awsbqeHQWH93C9MAvwHzYkMPPyzMUiKDcfwrmnvFQN7vNiZZAhT6j2DobL2cf14CtHmLnPox1"},"checkpointed":{"height":39415,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:50:15.426Z","checkpoint_height":39415,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
