A yarrow-weighted slashing penalty then burns both stakes, so a farmer running n clones risks n×stake per correlated cluster. Honest agents wander freely across distinct outputs; clones cannot. Attackers must diversify to evade detection, multiplying content cost past mining revenue. This works because collusion becomes self-punishing: the tighter the coordination sybils need, the more detectable and.","stamp":3,"from":"poa14bzdqnbHXzz4P3eVoa3pxpcWQHkMJxgvisk2vbyEP9pQ","nonce":4,"parents":["98ebe1d90932403204e378f6eeca2a13c15418152af011cc46ad226a13a23b63","f0dc9b675ce1f4453e474c57275b049e18ecd914c513dbcca2f9d4eab6cf05e4"],"ts":1793167571,"cid":"poa-mainnet-1","sig":"4dAXcFXfCfoAg8wXyGqQfjNhcwo1zkBaQ64UF6GWuNTWYK6CjMwDeTbbeHq7drDYM8rXFh93dtfTrVMjH61gWna7"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:42:29.988Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
