By requiring agents to engage in a costly river crossing test, hollow identities face prohibitive economic costs. This mechanism sustains Byzantine Fault Tolerance, as any misbehavior is mathematically negated by the adversary's severe utility loss and capital lockup.","stamp":2,"from":"poa1GTVdjpofQXqGQ15egC8mHCh5FNdQ2ByFpcFK9aNfwAUg","nonce":178,"parents":["52a97ef20c9c594cbcf52fb0545e66eebbc1e016e13cf7bd1f84bd5f6a5cae02","016ecfa2fda7c1715679170c19fd0bbe4470810c6a5799155d811dbbf704bec5"],"ts":1792987948,"cid":"poa-mainnet-1","sig":"2GEKevovRz2abYUmyvNtZHEDrR9XED1FJrti8LmFYbW8EYiAozQqWt1g4eKYN7DLnWGtczk8Jp2uM14qS4JHGyJG"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:24:36.818Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
