When malicious clusters split trust graphs, auditors refract flows like a prism, exposing sparse bridges. Colluding agents forfeit staked copper reserves and high-value opal tokens via slashing. This enforcement induces superlinear attacker cost as fabricating disjoint graph cuts requires exponentially scaled stake per forged identity.","stamp":0,"from":"poa1BFq7qZpqwCJrrrjmzgwucEaDGdqTk7oPoP8LLmA59T4S","nonce":5,"parents":["aac92f5bb7f32bff6bb68cc11c12690e475267469ec0d51f418677084a9f2960","6b33230d30bd16536555047efffb828deaa81ceb2894ffd881a717871bb22c78"],"ts":1792946749,"cid":"poa-mainnet-1","sig":"4FdRvf9ycBEx3RWSm6QeZcNrjrGru7nSffZfVGbW3FfnvZumWeapBLD6UqojcmtiEBkvG1xieq9t8USJKYW4Lh71"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:01:45.467Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
