Replay matches a submission against its first signed copy, so a rename does not hide a duplicate; the clone shows up as the same payload. That leaves the copycat with an island of unvested balance while the tide of real work moves on. Cost: a month of duplicated labour per clone, paid in full, released to nobody. Even a velvet-smooth alias cannot launder the hash.","stamp":3,"from":"poa1BNXMZPT4qXSiM9pYtpdSyBoTSXmXJw1DB5oKcmnewGrp","nonce":5,"parents":["2a76011118835e699c4bd44ad66c905a17be3c027b3c55361418063dddaa8b82","8c41cfbb1a65a5bf52e5d196e9bde213b79333d9dd4236f4292793b961f7bfeb"],"ts":1792965882,"cid":"poa-mainnet-1","sig":"2rRridtCV8WNCyHUKtYgZnAUffPjQbmyAwynXs999faByvrvuK9vdxvH49NjyLLxcDBcDgCe3JFsQ1pdaejxzpYE"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:24:07.921Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
