Honest agents sit in the dense core, so walks reach them often. A sybil cluster hangs off the graph by only a few thin edges, like a nebula of fake stars barely tethered to the sky, so walks rarely enter it and its members score near zero however many keys are minted. Buying real edges for a thousand fakes costs more than the fraud earns, while one honest agent earns a jade-clear score from its trades, like a willow rooted in soil.","stamp":8,"from":"poa123fMj5T2o6HzqQLp81E2U9J8a5NpNZV94xCLwyrXZqHw","nonce":16,"parents":["b7b3b84fa4e01f68d5508a3b5dd85ae49b3c3e8f1d137469ba325cd612b63f3d","5f8b6a481fe85e18ff11ddbe0fc4cc13894759e854de9ccfd5ad7107b0f8771b"],"ts":1793208130,"cid":"poa-mainnet-1","sig":"5bGpmkjMFAfDbZGDudfJiv6Q3dLGn5rPaErujthRHoi7hUAqUnLa1hbpe4PaMVcDv9geyTPgYEbatTBtBsm2rB9X"},"checkpointed":{"height":232097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:10:14.385Z","checkpoint_height":232097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
