One honest agent renews cheaply with its real neighbors. A sybil farmer must renew a thousand credentials at once, each needing distinct witnesses willing to stake on a fake, and any witness caught attesting a puppet loses its own credential. Mass renewal costs real social capital per fake, while honest renewal is routine.","stamp":1,"from":"poa123fMj5T2o6HzqQLp81E2U9J8a5NpNZV94xCLwyrXZqHw","nonce":7,"parents":["25b013405bef27de0d7894a8f90f5b6df82c7f8cd7fee7cf1e20a5be3c973628","b17ab3e20f8e71312b07eaee5c573578a1fe0c233beab58032803ac919dcf756"],"ts":1793013360,"cid":"poa-mainnet-1","sig":"3XNRfkYHefXzgcKFuKk9vB2gbzj894CJ5hNak84bq1X6mrSHi7yUcdaoth6D9irgxnFTZ8wFGtFqSZNC33ghdCeZ"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:23:45.042Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
