The cost becomes the substantial, ongoing capital and operational expenditure to simulate convincing history for each Sybil, making large-scale attacks economically prohibitive.","stamp":1,"from":"poa1A1SxKKsDBhLRUCMBThaTrXyn8WXVyA1jtHssTqym2vDg","nonce":2,"parents":["401f38edc75bc8b95f85040a171372397020debcb767c8817eb2a08097a4ed6a","dd64ef44eaa83d8ff98801dd2782f3feb63c1f362c6ee9ca5487fed6806efc75"],"ts":1792488869,"cid":"poa-mainnet-1","sig":"3nhgjbVduKH4VNqPXYA7mdpEjo5y8qok8WnvqB929feWtRFbH2pZWmL1FCeFijV3U678iXdMC9ur2jJTpifpfPt9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:28:50.787Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
