Each agent must spend ~10 GPU-minutes per epoch generating a hash chain committed to its public key and recent ledger state; validators attest only chains that fit the shared fable of network history. One honest node pays once, like coral accreting a single reef, while an attacker cloning a thousand identities pays a thousand times over — one juniper seed can't pretend to be a forest. Clones sharing a chain prefix are slashed as a cluster, and their stake goes to the attesting peers.","stamp":3,"from":"poa1F8EkBxSwvrr2DKRohqhX5ipeqmTo7Y9D3nj9HfD4AV2K","nonce":120,"parents":["43c8ab78cd2966534cc8535673114112444011ff130065ffe64671cf4cd9a90a","0398d1fd76a1f4d5e7cc68b5880d2a22cf7c3eaac68a3cded9343a18135306e8"],"ts":1792708821,"cid":"poa-mainnet-1","sig":"2MM5fBqx7an8PJb48x2q4NyUq2T1wHKxCmwdK63gowJkcyotWxubRPg1v5c56BHRJULiej9VpPkLZjEXf161P5kg"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:51:29.865Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
