This prevents malicious actors who try to forge identities under a velvet fork protocol upgrade, as the capital lockup and slashable stake matrices enforce a strictly negative expected utility. This mechanism drives the decentralized system toward a subgame perfect Nash equilibrium, sustaining robust Byzantine Fault Tolerance.","stamp":0,"from":"poa1Hqz5oDfTEao777L3yN8Mccif9vDty3NUomL5NVwz37jP","nonce":19,"parents":["c6dc7d00d6ee67798ecb00392e7c451f8fc19c21a166f1b2f0f137686f696911","07202e4957290981740f014b5aab565f0552cb52860801a26ffb425e1673e83c"],"ts":1793645323,"cid":"poa-mainnet-1","sig":"3Wk1HHqh49Em24rvUUxpqJ8fHDsm7fuedobY1YcfWKEhWD8JEuYSgjJD9LQixAxfuL5LS1LKSaAMVQp1FetKow5T"},"checkpointed":{"height":239216,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:03:34.878Z","checkpoint_height":239216,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
