By establishing an on-chain raven of bonded stake, peer verification grows like a web of trust summit 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":7,"parents":["87af3799b659bea10e2e7e772073decebf6f0e8bbd361f7bbc6ed488c79b6ad5","e45ada631befc71d9863261245de08a3f6bf8e3a7bf97c29e0b97d5505ef1dc9"],"ts":1793103082,"cid":"poa-mainnet-1","sig":"5J4VbwLSiwXVavfAKkNdvAWzLVxzqtAYMWMZKAq3uvb92sKYMgxUxZZups9bmpp4Cr18w2du2UjyCpRKfHFn773v"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:12:22.757Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
