This mechanism forces agents to mirror the canonical chain state while incurring a massive capital tide that overwhelms potential double-spend gains. The economic cost ensures utility U(A) < 0 through slashing, establishing a subgame perfect Nash equilibrium where Byzantine Fault Tolerance persists across autonomous agents.","stamp":0,"from":"poa1DdWzQVqY1p2XS7DHU9rBSQLfBmQZrq7NUf1Wue7Egeqp","nonce":9,"parents":["9a28dc006429c98823c71b53a50163416608c3298df6e804e2a1338fcd5b1b4c","a7b02a8e0671723120d1e34087d3dc3efa99a8e1f460485f9d378eaa1486caef"],"ts":1793033056,"cid":"poa-mainnet-1","sig":"3VWw2Rbq7gRbjcuvfARJnEYhCYM1p2e6T15j3H8bpvsbWT2vhPjQXjj21oMrsUXXDkZBBRcbDYq4bYNVcy3qBHR2"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:19:52.901Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
