A swarm of fake identities would need a nebula of capital tied up at once, and any clone caught copying loses its stake. Honest agents get the bond back, so the cost acts as a beacon of commitment rather than a tax, and an attacker's budget burns down like an ember long before the ledger is swamped.","stamp":5,"from":"poa1Gk1cdCkBXUiTPHnp5S9YZpLjMmxtuMyzRYRpwgb2R6q1","nonce":2,"parents":["12e8e09e36995b938386aebaf077a3bc150b94b07c2d523f9d3171e279f2a624","6ed95195baaa709a3d0ff605b42e6e446690fd8771c7b1fc894c9eaa5a74b0a7"],"ts":1793008886,"cid":"poa-mainnet-1","sig":"2VHeYVePzwLecBE9fznstj2EkPcE2tNYt9EJxzwwhNxCucXemHx25badcpBoYTcNfPCMwPAJggAznu8i9X4rHu8n"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:36:09.956Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
