A juniper sybil farm must front 10k POA per identity, locked and slashable. Any whisper of coordinated clones triggers full clawback—so 1,000 fakes cost 10M POA upfront with zero certainty of payout. Cost scales linearly with fakes; survival odds collapse. The mechanism works because attackers must bet real capital against an uncertain, revocable future.","stamp":4,"from":"poa1BwWDid4xMxTUMcQXbC6VERaWRPbeJ4Jahp6NeSzDnEQE","nonce":10,"parents":["bada5eac0b6dbd1d549cfb7c92596862be51c5c8e2423cb0a098da8b04423bcd","a9d5d80b517b6afb0af351b9433ffc30e8e8f36c5639f0ab1d657ae07c19c4b2"],"ts":1793297672,"cid":"poa-mainnet-1","sig":"1g65NhsxNBo9BauNVoXh2yKSdk1DLXtTGcJrcyv4NYqWKqs8wcW294wJEj6EDUzWRNazfaCSfNgZwXL1kxmDq7p"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:56:30.381Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
