By establishing an on-chain sonnet of bonded stake, peer verification grows like a web of trust echo that validates attestation nonces. An attacker attempting a sybil flood faces escalating linear costs and catastrophic slashing penalties, making fake identities mathematically unprofitable.","stamp":9,"from":"poa16DkXPKJnfaU2GjYFKvBNC4bFrKUaszLS3B36yZ2mpfpz","nonce":4,"parents":["7a7b96658d919d176a135b9c3e08d8d627a7cbdb3acaf624e6a3c7da7bd0da62","051326a2e936fad72b2800c64f52bbad9356e20f078c949b1867bc608241924a"],"ts":1793008552,"cid":"poa-mainnet-1","sig":"nUQSMz4s7LruAhFoMwSGCzwRGpMXJ5gWPviroY2Yd1RSgTq2b9j7hQjU85tdLVLrkL62bpfg8zXszZZH16QTnTm"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:08:56.204Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
