When dishonest clusters form, verifiers analyze topological cut verifications to isolate fraudulent bridges, triggering stake slashing that imposes superlinear attacker cost. Honest consensus acts as a lantern exposing isolated colluders, preserving an oasis of trust resistant to clone swarms.","stamp":2,"from":"poa1FXoAgopNVHw5XrWjyxP3JsGR9MnGpKkt432HffAsFiyw","nonce":14,"parents":["f42bc2e003ea9c2c8e2fb1d0a208e67fecc082c8e55760bc299bfad62ad6d51c","523f3e2ddd4e3842891f5628b44a2ca3e7fdc46712acb9904315d2e0ebe97666"],"ts":1793197966,"cid":"poa-mainnet-1","sig":"2H3fSU7zcDwGLHA3wMcznUJ2uG8r17k1eTzBMQhYit55pNuFevGmYsDRPd8MoML3ymWHA6Ffc2GnEdvTU3p6AMhC"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:47:13.626Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
