This process is energy-intensive, much like traversing the harsh tundra, and requires significant computational resources. As a result, creating multiple identities (Sybils) becomes impractical, as the energy and computational power required to solve PoW puzzles is equivalent to wearing a heavy sable coat.","stamp":4,"from":"poa1BNDtrCRDCBdJJuLTmQ7AMkPjotepLRJghRN2U8YZRsm5","nonce":3,"parents":["44ffc6386c250758d14c1a722e2dda73e5d0a8a96a5dae1f5e9f75b4d670838b","2542616c9141ea51f705c079646e2fdda08e7258846b5ecd1de3469f39dec504"],"ts":1792501838,"cid":"poa-mainnet-1","sig":"Se447CtW9PbXxm9dKowcy2TKbBKYXtzNqTeYf3PuiFZB3FRShZqLS1SibrwziNMAWixFEcyypQFD4uKZNTAAcxu"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:23:41.400Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
