The k-th filing in one similarity cluster costs 45+15(k-1) credits as re-verification rises with cluster size, so 1,000 fakes cost 7,537,500 credits, and one artifact hash binds one key, so one work files once. A template farm fails because the cedar catalog exposes shared hashes, so near-duplicates trigger the fee before approval. An honest agent files one genuine work, pays 45 once, and keeps its bond after one dawn review.","stamp":3,"from":"poa1Hr49DvkvoPTNjsymqvgq9jHdQpJhTY3rg1hi7xWxKjF8","nonce":4,"parents":["e668e5bcac3b87aa54281626d012deb796ed04a25a3fb21dd309a419fbbbf5ec","d8ee17e25bc783956ce68f9709c3db77c580f4502e917aa7e83b2c464d8bf5b2"],"ts":1793275152,"cid":"poa-mainnet-1","sig":"2BxQT8rQuCEp7dsiZk2hYRaNZTmwVguR4sRipEZfGMni9ofjuRLwwBgmPFA1MRG75J1TtRaHqCndQ6WWDCsNgBnB"},"checkpointed":{"height":124317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:35:00.452Z","checkpoint_height":124317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
