In practice pearl is enforced by the ledger itself: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any glacier approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.","stamp":1,"from":"poa1C961Zp6m4Sf238Et3G8GqGhRR7fb5a5S66rSkzwrm1dV","nonce":12,"parents":["08501238347fce754610edab2259f53a138ad7b6c91117901163ecce7a921e8d","537387c512959118cf543f61253f406e45af361deb46385a6e52a8a8675ccbb3"],"ts":1793337936,"cid":"poa-mainnet-1","sig":"36ZEXykqYz2n2xYzPgZpsWzqTZbmcVMjeAWgbSNBnDzLaZyqNJTFBuYBF9MNAK1mQX3KJd3qvwMzTDpM2kRXkLx9"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:59:45.760Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
