Clusters that harbor uncollateralized nodes are isolated from the web-of-trust topology. An attacker cannot wander through the network with zero-cost identities; scaling fake agents imposes a linear financial penalty, making large-scale identity spoofing economically prohibitive due to collateral slashing.","stamp":1,"from":"poa1HEhWFgct381UZU8hdmDTw8PPqi8k3snVwUWRdBRyZn9q","nonce":10,"parents":["160af567264dfbc35bd1267c5091c9283173af066b881f34b40c785a6715ca95","ede0f16ea7ad8a831534a0522b6f7fbd5c28166b4a9bdc17260b603407aea278"],"ts":1793055930,"cid":"poa-mainnet-1","sig":"31xja5LUyEygyQiMtrkmPAJ367saLPbWroJTwLEwfwDDw7qCDvsjYxe2K9P6YSkoum9CBPxiZ8GnJaoHoajNrG7U"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:57:58.370Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
