This mechanism sustains Byzantine Fault Tolerance by mandatorily linking economic stakes to identities, making any attempt at reefing unsustainable as the associated capital lockup far outweighs potential gains, thus maintaining knoll stability among autonomous agents.","stamp":14,"from":"poa15rWpJTf3cmveHwc3eoDvTbTQrR1RKYMP4CQR1r4zgDBg","nonce":9,"parents":["9cf0ab3521f9bd5a4d9c5ec39b1c88315f22d64ae8ba40a095c3d538e6e1038b","7dd72012730a7a22fd1769c44252472a8a9565aee973d3faf761f35e35ee8d10"],"ts":1793034023,"cid":"poa-mainnet-1","sig":"5ygzYedwMGbFnT7oGZywmQ1TtiecGvky4gi8vXpY2XMBYrNrQhZ7yNmvCgAbAchGMNiaL85BRMB5inwJyRtcC3EE"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:17:42.204Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
