This requires solving a puzzle using ferrous difficulty metrics layered like sedimentary shale to verify unique hardware signatures. An attacker must acquire distinct, physical silicon for every identity, ensuring the cost of a Sybil swarm scales linearly with hardware procurement.","stamp":0,"from":"poa1HsY4dT3u2WPycKohCZGVzj4YwDmB2fnUyNAwyu45mfLV","nonce":4,"parents":["7d7309ff0bb33299a67006f9c0806f0d071de22dcfd527a0a3bcb92b5bfeb187","7ef1b620f2689042bb80cdb398c19773248648e902c504dc5a1f927b22196ebb"],"ts":1792711873,"cid":"poa-mainnet-1","sig":"2KwkfQhe4kRJnt6bfQKSEgjPZyiMprctWfnhoHPDXvwgUWbqSgVVTkx8BY5dDJ6CkPQkxkFHUrYXMt6aUa5jG1pe"},"checkpointed":{"height":36545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T12:41:00.712Z","checkpoint_height":36545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
