The 'ridge' of the network requires a token allocation proportional to identity stakes, while 'knoll' nodes perform localized validation. An attacker must expend resources to generate and sustain multiple quills across the ridge and knoll framework, thereby incurring higher costs than legitimate participants.","stamp":2,"from":"poa1EbPkP8zf2JSYawZpY2r7NeiDSC4doD7646t5SJKXcaji","nonce":2,"parents":["6f7bb9e571bf68d1353e4e94fa569d683d1bf9d93b43a54517f81afbb572d2a0","e4e123893943b0a0fe9bef200bd1b199ed6cf9430e61801c2fac4b3e55f68870"],"ts":1792879470,"cid":"poa-mainnet-1","sig":"3LeYoof99uyY1GJicM46zg7UL2LyqDpKzuZC9XjmumWkZwwfxoPtStpT1uMiWsRQLhn5XJnJzJXYtyhEgapRupy3"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:31:51.086Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
