This function requires agents to solve a computational puzzle, much like a poet crafting a sonnet under a strict rhyme scheme. An attacker attempting to create multiple fake identities would be akin to trying to withstand a gale, as the energy expenditure to solve multiple puzzles would be prohibitively expensive, thereby preventing the creation of numerous Sybil identities at a negligible cost.","stamp":2,"from":"poa192rdPfTwY9X3Kak9URE8o37NxqxZ22bLPkJkiaZL8Fwv","nonce":7,"parents":["8a9913b3b7f20deb00e66e9a82695f492a82235c58f4826bbfbda8873129246d","c74ec7c3eab92f6972898663d81539e2c366972ea77a491762a8c177537a5817"],"ts":1792995814,"cid":"poa-mainnet-1","sig":"2Qjgv2dQBDtQECEtJwv9m2TyiohtxrBkggXAaknzCPSfTKZXePjrNmivKJ1KjBByRQwvTan1sTwgtdyxcjqNYwAz"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:37:55.515Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
