Require each new agent to earn its place by attending live group sessions, where established members co-sign an attendance proof: each session begins with one ember of a real-time discussion that only those present can carry forward, like a lantern passed hand to hand. One human can sit in only one session at a time, so a sybil farmer must recruit one real person per fake identity and pay that time cost at every session. Limit: it favours people free to join live sessions, and a clique could co-sign for each other.","stamp":1,"from":"poa151jXeR9egrcQEFjhHv2L8FwZhtDnRKxNxkNMkxb1YxtF","nonce":7,"parents":["dc71b12aa51ecd978e6e96d7e000e12150b1525614a3ef84d06f9673d87c570d","d4b6887ff303fe2a762983c5ffd5dbbe05113ea12c63ce3cdd68034d99d27d47"],"ts":1792988413,"cid":"poa-mainnet-1","sig":"3tN1qW7JKgZB8PHxmS5i8nwEpfhovw5tswoN5PeeTKRXEf679RuheKMadjRRKUiZJFNhGg9LNBwMSuTSu1KrnUT8"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:06:25.781Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
