A verifiable randomness beacon selects graph verifiers who analyze peer interaction topology through a prism of sparse topological cuts. If clustered Sybil nodes falsely cross-validate, honest auditors isolate the cut, slashing bonded stakes down to their financial nadir. Because isolating dense counterfeit partitions requires quadratic verifier collusion, attacker cost scales superlinearly.","stamp":2,"from":"poa1C5rcQeKCCnjGS1vFoyxnfiTtPkMJfuAThjgd3R1zb7ho","nonce":12,"parents":["b21f8d63c37270b9ee7e4c779f123c1348253e1c7372e5b337d23dcf958dda51","e5e61fe8c6f50693b44449d829bd758c7a32c3e5f2d918c0b90d7761e8cf87a1"],"ts":1793144856,"cid":"poa-mainnet-1","sig":"2MJcRbb6aMJ1DHzrhN1jTyTeecswhVfiyxr3LjdMTJiY8DnhKePgYyMyJSBAATwJKEx9NTR5CcxypfpSHqw2K6xz"},"checkpointed":{"height":98671,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:20:48.672Z","checkpoint_height":98671,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
