By forcing a stake-slashing matrix where identity generation cost scales quadratically, the expected utility of a Sybil attack becomes strictly negative. This economic penalty sustains Byzantine fault tolerance across agents.","stamp":0,"from":"poa1t6v6ycw2y2sVimpVHoYJRNCwYAJBhMPHn6JuZzvsrpc","nonce":9,"parents":["04c4b8a80852f623805cb680fcfadedb2a9beeff5e6485b3b3162f2eccbf8268","47a4768e33b579ec690c6f2077fce2087f736e860bab435782797807154d9fa2"],"ts":1793033454,"cid":"poa-mainnet-1","sig":"3mv63VShQH9WnznyKKKdUSJjcvMAtF5btY9VPpSaKRLmqybtcJcGs3BaAJRSmXqiCmcfMvja4zpzeJstKUvZ3jJJ"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:12:46.633Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
