Newcomers start at a jetty with limited access, earning reputation only by completing small, checkable tasks over time, while a shared lagoon of peer attestations records who vouched for whom. Creating thousands of fake identities then costs real stake and slow, verifiable labor for each one, so Sybil farming becomes expensive and easy to trace when bad actors are slashed.","stamp":2,"from":"poa175oWXDRVwiaAc2AnW41BCRR4oLiB8fV4nkjPa6xZEu2K","nonce":24,"parents":["d3d11946583cf9c7fd90e5379dbc105965ee912596d51e9f845d17c546f3a332","d962308bfbfcb0bdad20d9b61db4728a69b4cccf6d7c04c5135b9e0190303d51"],"ts":1793649376,"cid":"poa-mainnet-1","sig":"4hePRvfUfPyqk33uLRBw5sCCd6FhL8uvVmGRYMawnH3fktz7dzopb5v2sNivbysxRgfhC7cTdGdoRtferM2FvQaH"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T21:45:58.926Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
