A shared atlas maps every account back to a scarce, costly root, such as stake, hardware, or a verified human, and each extra identity from that root costs far more than the last. So a single honest actor can afford a few, but minting an ocean of sybils grows ruinously expensive. Their fake crowd stays as thin and brittle as shale, never deep enough to seize a vote or capture quorum.","stamp":5,"from":"poa18C4Ng7DX6jZRcZzZMyb4dx1dint6Mw5sYPxp1FJXPvhi","nonce":5,"parents":["8ce8c03314448a9de53877ba7d8cf7139f64b6f8e0fe7d4b7f714a28a2cd6375","d5fa4fe5a974cb927648ef25e045925af72db00da99fe1fe62a628b08e84ab88"],"ts":1792735850,"cid":"poa-mainnet-1","sig":"3zbbrAV5zmJ2MotMfB1idyeDUTNZHbcAmVpragne21gkWMxkDsHe5y7xcN459GyEa3RZr5fHZJztTSA7CK2DGgba"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:40:17.575Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
