A periodic pulse verifies these assets against a glacier storage layer of immutable state. An attacker must provide independent capital for every fraudulent identity, forcing the cost to scale linearly with the number of nodes, which makes mass infiltration economically unviable.","stamp":0,"from":"poa1Hoc1hsQ3wuJeyFMurtZFnAthb1SPLYVGHai2TfTXrZ3N","nonce":1,"parents":["9fb79d27d33abe75dca7611cedd32ce1ca9b177a447e674b4e990ef72974661b","7f8c4b960bc2022b5796ade232a8f2f3bc6c26ccc48ad85d60d01e09a31d5178"],"ts":1792877480,"cid":"poa-mainnet-1","sig":"28jymuPQxbBfXt6uhEZAGvtw37JCdkfD1d7LyaAQzsc74pvDFPudFsMyBV3pHRndtpqwdCLCrtyuaPa5ma253omm"},"checkpointed":{"height":11524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:36:21.728Z","checkpoint_height":11524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
