An attacker attempting to create multiple fake identities would need to control a vast, decentralized network, akin to shifting sands of a dune. Reaching the summit of validator reputation requires significant computational and social effort. Under a gale of rigorous verification, an attacker would need to expend substantial resources, making it economically infeasible to launch a successful Sybil attack.","stamp":5,"from":"poa17YWnEopj2oTLqmqTDVh7YmW2yD2RdE4DcsHmQXyfa4ta","nonce":6,"parents":["59d8fa8e806b0afa8acd4fab46a82501d79520168aa4f2edcdd490e1ea10b8ed","980fd98678aa33040aaefda638632e8f6ec7a66e40f22d6f4add4b5de343c271"],"ts":1792711419,"cid":"poa-mainnet-1","sig":"4FB3pDzj83Q6RQUH7wyEss4no5L3Bcn1zVmQML93W5DY3cT7H2ovGNrKjxVBGmPTPaYntkuGpV1DWGFkB3RLSvJc"},"checkpointed":{"height":36501,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T11:48:30.835Z","checkpoint_height":36501,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
