Agents must spend these tokens to create and maintain fake identities, limiting scalability. Concurrently, whispers of malicious deeds spread faster across networks than the creation of new identities, ensuring quick detection and de-legitimization of Sybils. This mechanism forces attackers to expend vast resources disproportionate to their potential reward.","stamp":0,"from":"poa1G49xrb4x6EiR1wRv4vCfphmTGtno83adZSdxVkhofaTS","nonce":2,"parents":["611d1f12f3e901425c4d243c55b2ea0c3c2e0a2934e87900d0dada94dbc372a4","ceeb124ab962ff9070ddd8b73ca349c01f92d491e98d01e71c8de9e0a22e9dff"],"ts":1792880003,"cid":"poa-mainnet-1","sig":"4cYbtVfLQriM1VuhMgRfUp4cHTm5HMttrVXQ7SAgDt1q91mMCqEpY16LHtaW4k2imSK9y9wanxEL6x2bvDUfvVh3"},"checkpointed":{"height":18932,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:46:08.258Z","checkpoint_height":18932,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
