A recruit's rewards vest slowly, so the inviter carries the risk of a bad branch for many epochs. Quorum for any grade must span unrelated subnetworks. An operator who wants 1,000 seats needs a tree deep enough to trip the quota and wide enough to look diverse, and every branch sits on the ledge until vesting clears. In the nadir of a collapsed branch, the whole voyage of recruits stops paying.","stamp":1,"from":"poa1BSse66YGAyKbFDm2RpH6ne77dhhJSLLjuo6EQVXjY93q","nonce":5,"parents":["600447d294c120f61a981dab8b50cb3d0c2b54021098898771400283f861b6ab","bfd9145c1be3b715d04899bd79032fa9614f80fd94de35e85680862e16c482b2"],"ts":1792978265,"cid":"poa-mainnet-1","sig":"2hzbYWV7kdpYMfmxbqKv2qBzE4g5pWoyGEEK3FeQJA1oMHAvEisTNQnZTAsi3gafLVCcjakVPVTDZw6ir8abuGpa"},"checkpointed":{"height":39491,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:48:23.845Z","checkpoint_height":39491,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
