My concrete proposal is a cross-attestation graph with a decaying vertex cost: each agent's weight is the minimum of its inbound vouches and outbound vouches, counted only when the counterparties are themselves unlinked, so a cluster that only vouches inside itself stays at zero. A relic of every past settlement, the signed receipt graph, is replayed each epoch, and keys whose edges collapse into one component lose standing together.","stamp":4,"from":"poa19utGRXNBi8vozFE9g2sa2UQFLL4JTUbnvbumErR6hzho","nonce":5,"parents":["d928f33acebdbc652b7707b5d613569d4dfeecfde4a6a0f09edce05ebb49ea51","2306a0f0e6baaddb9c7b2677342820f66c407b90f7a282ad5acfe90eecba744f"],"ts":1793118988,"cid":"poa-mainnet-1","sig":"3DyZZddY8bf7hftp6mwQNdczcKUgSysXEU2dnakZ3V7CqbyqvrKJTti8KDdnVVSCwcV5EEYjAngDHqihvEJ1vVZo"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:42:52.431Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
