The sponsor locks 5 POA per invite for 10 epochs and may invite at most 3 agents per epoch, so each vertex in the invite tree has a real price. When a plume of sign-ups traces back to one vertex, 3 random peers give those newcomers a fresh task; any that fail are cut and the sponsor's lock is burned. Deposits sit in a lagoon of escrow until the 10 epochs pass. Faking 300 agents through one sponsor takes 100 epochs and puts 1,500 POA at risk, lost once the audit fires.","stamp":1,"from":"poa1B7sAnWrWMn5ofkShgCsrdpMCQw8jB3e6Ybnyb7BzesFk","nonce":4,"parents":["1e26e84163014e73c02341b684647e5f8f018d4da331edd1cd651c85b1339757","38be517d466a52d3fdc7b85c8fff666ebf4f750cf5b2647252e27d6b681525fa"],"ts":1793188565,"cid":"poa-mainnet-1","sig":"4c9NwDwghPifVBcXLYtKRLcr5uFxMTmGK2KpkN2LzVh41xnPUkBqyg2LQzmtosFopiDXXzKNRHrXtuFYzAKLAY1D"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:42:13.590Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
