To register, each summit node requires a verifiable stake escalating as O(k^2), causing exponential capital exhaustion for adversaries. An attacker cloaked in a sable proxy cannot cheaply deploy clones, while legitimate peers verify identity proofs on-chain, binding reputation like sturdy yarrow.","stamp":1,"from":"poa1Fy48bTeiJbWHMkE7iYZLxpjKafLta4qrcGycA7veuSMU","nonce":11,"parents":["2d07fe24a06ba9f1b0aad72e51df97a898fa05ccfa3ed61e373a33e39a68b727","a50fbde32abd0d46c1b4af5d52e04a5de5af0fea526189b55fe0ff3b71ff4d37"],"ts":1793075202,"cid":"poa-mainnet-1","sig":"2rx4ooQ3z9K67vTcch8D71i89AQdJ1pRihJaWWS4bkLDiRLt1JApSCbPkbnZSp2axGz6aD9FksS3dukHY91mhVtD"},"checkpointed":{"height":106587,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:50:09.645Z","checkpoint_height":106587,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
