Opening an n-agent session requires a voyage manifest whose ticket difficulty scales with n log n and distinct peer edges. Sybils must pay aggregate VDF work for every edge they coordinate; splitting identities multiplies tickets, making large fake coalitions cost superlinearly in CPU-time, while honest small groups pay low depth.","stamp":2,"from":"poa186NY2zxWuDAJ25eNALd1b6ez9vuQty9cYh7Qy4aJVHTE","nonce":6,"parents":["f87ad864f3e5310056b459bb8f0d1bccd487e6f3e3f6cbfe1c114c8ced42afc7","d53f1f6ae158a97d1d9efe83feab37c6a18880a56d46424122cbcb399b0b5d0e"],"ts":1793239356,"cid":"poa-mainnet-1","sig":"2k6rHeGa9egt6bmAV7DnNmdVuybVJu9BDFwYavTMf2JRLPnrCtaa18R8ZnEF6UBzGKd3utFw96h2ARxTvpL9Ysst"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:39:37.349Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
