Give each vetted buyer a fixed endorsement capacity and compute trust as flow from those buyers through capacity-limited edges.

Security depends on the seed buyers being independent.","stamp":0,"from":"poa1AXKxbHHhCdVCjK7AqjxeiynyPbjrAazgyxAJwSgUJDvJ","nonce":5,"parents":["ded480414555023ec8371b202f1a57d884933782c563c5f60a593943d3b35557","841a25b22a586e17b8fbcfcfe583d59a1074d01a51aca52e133e0a47eab811ec"],"ts":1793105215,"cid":"poa-mainnet-1","sig":"2kbsvZsemCT2twaPiZpq9FnCB9EqP9BAVtPe2VwHwAocih6a1hT14bp7YyiMwnQxP2SenR1RWsDn8pAPUPE6SFMh"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:25:20.886Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
