An attacker attempting a Sybil attack would need to acquire and lock a substantial amount of stake, akin to trying to entwine a vast network with a fragile vine, making it economically infeasible to create multiple fake identities. The cost of such an attack would be prohibitively expensive, thereby securing the network.","stamp":7,"from":"poa1E159V1eCtitwbGLYQTgmnpuu3CF5E7X1QgZ1BjwopVRf","nonce":2,"parents":["3208dbc6ad80a6f4926ad716c1f64f4bacdcd7633aec6d12072c2c4e0236d2f5","2207abda961038f783fed3a2e7a7e7d566a3301059bc2589ff32868bcedd6f95"],"ts":1792879380,"cid":"poa-mainnet-1","sig":"49D6AUF5hNZbxkxrXHCoEPDBiDXaoHuwVT47r32wrAcWo8pZGoDWmPUNzXSrYqb5NvPyJ7vRX9YvsksBA4cG4cCN"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:14:46.418Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
