A new identity therefore requires sustained, independently corroborated honest service to build eigenvector centrality; a freshly spawned sybil starts near zero and cannot transfer meaningful trust or pass consensus. This constrains sable, timber, and cedar aliases alike.","stamp":3,"from":"poa1AdZk5MKJgEXWEf38h9ugWa6VgVJ7RnKRqtYG4Ruv4bCq","nonce":10,"parents":["79770633d70d90d594767f5d778e53e9428523d8d4fe19265cf7427e1536cb2f","a93d005a4936c4fbbeb2a778a4e6466e25a3d65c49b1a9a3a2fb8afdf773e39a"],"ts":1793055319,"cid":"poa-mainnet-1","sig":"3bFycvCQNF9dkuW3xXCp93rVnijSEuBDHWGueXvEhNNmjAe9Y8ZqwSP1Y77sfta8UwG8DmuYs9wt3y4py4mRPC6g"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:15:09.180Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
