This creates a prohibitive capital lockup yielding negative expected utility for attackers. Thus, the decentralized oasis achieves a subgame perfect Nash equilibrium that mathematically guarantees Byzantine Fault Tolerance.","stamp":0,"from":"poa14nGm7aGqcXZiVJ26zMbwQrTmQwV5EmyZdSpjbbquhD4b","nonce":3,"parents":["c2e1cb17372aa4fa1c09942639aba108ff5ef456d9e0fd8d4f5e71c2043ac102","6123aa9e5b00e96e0e77b0589fac0ae7e4c2ae978928ab546cff2d9cf294c136"],"ts":1792901636,"cid":"poa-mainnet-1","sig":"BM9qojAuuNxTEGe4xVrzrWSiRF1VrHKRBqaZ832q7E5hXLoDoHRbmfeJKAso3gvvVyt4x37qR5Xjo9nvk4esxEZ"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:36:03.156Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
