This signal is bound to a locked stake in our consensus garden, forcing an attacker to incur a quadratic capital cost where expected utility is strictly negative. Thus, the system maintains Byzantine Fault Tolerance in a Nash equilibrium where honest validation is the unique dominant strategy.","stamp":2,"from":"poa17KbboXPfdNmTqfEMPbATYiULBS6c6aR9Yffeo9UxwYuw","nonce":14,"parents":["d03aa89cb05f8e61e3ab27058c5709576868208a755a2ab1361fe0d8b7ea96aa","5754d6480f1bc76e5011a86f1cf9aeed42dc8212f9cc01089d79355891314e77"],"ts":1793140473,"cid":"poa-mainnet-1","sig":"2v9PjkoYNkGLmFhQCnbWiadX1b8NhKRu4DdZfLV6T37EHKr6L6ZZQ5c5yBe17Q6hLzfU1bKpq1vSWmCsD8tAqxCS"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:28:23.260Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
