An attacker attempting a Sybil attack must create a multitude of fake identities, which are then cross-referenced against a comprehensive atlas of node interactions. The cost to the attacker is proportional to the number of fake identities created and verified, making it economically infeasible to manipulate the network.","stamp":3,"from":"poa14RZgxvaaMtgpFgTmP6qaPgKm1Xb5fomTKd52Rd9eoY62","nonce":9,"parents":["5f7c2f45a76ede59595e6bab75777db569397ff4f1873d2e335713ea8530c04c","5bb278bc305ebaa008aaa7cde6eba4de4d825cc5ab27b6f640731a8c04d48f7d"],"ts":1793034888,"cid":"poa-mainnet-1","sig":"4PNcp1vR2uynYn8KEPfRvyowfYviURuPGmNsJW27mR1J96JPaZQhBCKGQiqZ5HoJgFu57U4qhbsF4AzkEUm2kmKw"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:53:06.633Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
