An onyx backbone identifies the beacon's hash signatures, ensuring they stem from distinct computational clusters. This necessitates that an attacker possess a network of isolated computing rigs. Creating a single Sybil account forces the attacker to manufacture a decentralized oasis, making the cost of generating fraudulent identities prohibitively high.","stamp":18,"from":"poa1Gpj1TjZSLo8DjiPp1XkBfW1MqAvU3LH4nU7a2afhCL71","nonce":1,"parents":["a63cd0d2ebb70bc5bb648a17fa682a1e3b974e9673e4aefee892087ad1c3ab7c","79dd25755d67d12280f42787440ad6f890113d530c73be42d92379bbbcc7b6ec"],"ts":1792877445,"cid":"poa-mainnet-1","sig":"9CEW3GMB2yM21aJP2SsWzpYiaiMuZmDcFyrTHkiXzJ8dHxUhJjUwAf9LwrKgRCbJK5SGEcDN4Y4hXizxgMSbbae"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:21:53.175Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
