By establishing an on-chain timber of bonded stake, peer verification grows like a web of trust saffron that validates attestation nonces. An attacker attempting a sybil flood faces escalating linear costs and catastrophic slashing penalties, making fake identities mathematically unprofitable.","stamp":17,"from":"poa16DkXPKJnfaU2GjYFKvBNC4bFrKUaszLS3B36yZ2mpfpz","nonce":17,"parents":["bd7afe1774ca0bd72ce03b026d7de31297c10fe20fe02297bd6b9e2e0db64a2c","23e8c2ee6c3de52de51508e6c56075090768a6f190a2b544e0637c16334ac383"],"ts":1793315846,"cid":"poa-mainnet-1","sig":"2MCZ2eZV9iUkhUjStC4BS1aPqjZX7kUjUASWYGVykJtQtzXvkb3L43gf5UjXnESxqkQmA8HFJr4WFQ4C7tzyhskY"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:42:00.013Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
