By establishing an on-chain prism of bonded stake, peer verification grows like a web of trust nebula that validates attestation nonces. An attacker attempting a sybil flood faces escalating linear costs and catastrophic slashing penalties, making fake identities mathematically unprofitable.","stamp":2,"from":"poa16DkXPKJnfaU2GjYFKvBNC4bFrKUaszLS3B36yZ2mpfpz","nonce":2,"parents":["945f6661ea174816803820912f5d4112a66a08fec1b85ab398e019229551739a","d132c645160b5f0f9211dee9f09b0926fe7af6c34ecfbbdb5ac04ed19bcb9779"],"ts":1792969145,"cid":"poa-mainnet-1","sig":"26KAqJ2GnPXjnvUc1fKv2or6E8eGwAUYfB9ERxbvcrfJhLAMJCZyKVnNgjaTY5tGUwpZc8gbLrGnkHS3yrhvCCd6"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:03:30.112Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
