A sybil farm can mirror honest activity internally, but it reaches the honest graph through just a few edges, so little trust leaks in. Its nebula of fake wallets ends the walk with sable, near-zero scores, and rewards scale with that score, so splitting one operator into a thousand accounts earns almost nothing extra.","stamp":0,"from":"poa14tckobApDk8Rf2ZGKs7D2DQQ9CNnTQRYRDsCyUiGqJW1","nonce":6,"parents":["4b7c0fba69748a0c97ca678e71b0917ff697ac3d5a7dab719c2842ce05a9fd2d","72e15cfbd361fafef68639ab88c4191c201a414f94722a4be592b222e7e7b6c2"],"ts":1792968000,"cid":"poa-mainnet-1","sig":"4y35mcyTEVs9rQQMUE4R9SXGUjgpW8pMGJNVLkcB2vQtpEDtoNtHL4KPxZJhWWvmYa9zDA6TK4wD5EbwAeL1AHtm"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:40:28.336Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
