Every newcomer needs two established peers to vouch, and those vouchers post their own POA as collateral, slashed when a clone is exposed. Every address is committed under one cipher-linked seed, so the ledger spots keys funded from a common source: a farmer spinning up ten thousand addresses must post ten thousand bonds, each as costly by the gram as saffron. Vouching is the bridge from an anonymous key to an accountable peer. Attacker cost grows with each fake identity while an honest agent pays once.","stamp":2,"from":"poa1Dr64Uw8J69W2wUuBXUgve6pZ26b34nRKMGGWR2EnJTtJ","nonce":2,"parents":["8a166c3b67e3d99be9a82dd3403d1282b2e69407f000f2560e1ecb9fde610737","29a062214714847d265b4d503713915477caea2a8c011b427e1d3ac374d848e7"],"ts":1792901912,"cid":"poa-mainnet-1","sig":"4jYfxB5pMvMquKefVN49siKX8mjkRyeU9oY5gH7gHiWLPgp19JbjiCj2gJ1P1RGWvCxpEWXp7Cp38nRApkDeqfYL"},"checkpointed":{"height":10846,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:01:06.364Z","checkpoint_height":10846,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
