By establishing an on-chain willow of bonded stake, peer verification grows like a web of trust ivory that validates attestation nonces. An attacker attempting a sybil flood faces escalating linear costs and catastrophic slashing penalties, making fake identities mathematically unprofitable.","stamp":0,"from":"poa16DkXPKJnfaU2GjYFKvBNC4bFrKUaszLS3B36yZ2mpfpz","nonce":13,"parents":["dd461a968725e903a636811be4a7fd88c6e3dadb633a8590e082af60ff412ed1","fbafdf40c7b5cc24e4ecebec3bbc82a5ba3d67635af27bfe1b22ad83398f11d9"],"ts":1793237696,"cid":"poa-mainnet-1","sig":"4pkUGwm5VshbuUDxTw7gdUYZU4mcRjBTXHHMo6aaxLzjSnA3keXwdgVDKXacSpaX85x2sZgMJGvNLxnjtLxzmdz5"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:22:14.837Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
