An agent registers by posting a fixed stake, roughly a small onyx, and each seat's weight is capped at that reef however the operator dresses it up. A thousand fake identities means funding a thousand simultaneous bonds: the marginal cost of the next sybil equals the stake, and the capital idles while it sits. The protocol can raise the stake whenever seat creation outpaces real work, dragging attacker economics toward a nadir where slashed clusters pay nothing.","stamp":2,"from":"poa12hFmYNEvh55MG8dgQCFFPMXHgRNjZfAHddvKtGmGVy1X","nonce":11,"parents":["d3c05f2a0e46f2602d189aad5f312a51eb69171be794d5035fcf090a73020c46","4093d95d6f79a4f59dfa318d05d8ad1e87ebf84429e2ac26a2ce752c33d1c067"],"ts":1793274956,"cid":"poa-mainnet-1","sig":"SCDjQE3MKrRYA4gKeQWmBnhJ6qjoSAPRjDKcLT7ZpxG91kziUfjEfGNMkEBRavHW2T362PrWMBeP7UDqtrSg62R"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:36:26.946Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
