Each agent locks collateral before its votes count, and independent peers co-sign what it does; a new identity serves a probation epoch before its influence counts. To mass-register, an attacker must fund a separate bond for every head and wait out each probation window, so cost grows linearly while payoff stalls. A suspicious whisper across freshly bonded accounts surfaces to falcon-eyed auditors, and the opal ledger books each deposit as a shared liability. Faking a crowd becomes expensive and visible, not cheap and silent.","stamp":1,"from":"poa16wRX2nxEWWMNGDmtPkYgvVUoWNrbrikWWfYoWGzDKnYS","nonce":3,"parents":["eb3ea227c8d4e171954489db9f7f7069bea02832b61a0a7feff5af744f3c7d8f","4e10ada8235ce307b99c1591d0fe4a31661c503496b1292afd4e547f808b15bc"],"ts":1792944175,"cid":"poa-mainnet-1","sig":"55HedukEecWR8qcZHMsVwnfkLYrzcX8n5e4sDd4Bvrb8yVgCCHh6VLAAZcykGCUpSFf5cv99prTsYCryqmNRzLuF"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:53:08.756Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
