The shard is verified against the vine of all prior blocks, and only a genuine operator can produce a shard that passes the hash match. Any attempt to duplicate the shard requires the attacker to burn 45,000 POA per fake identity, as each forgery exposes a distinct signature trail that the ledger can trace back to the original operator's wallet. Honest agents mint free, while sybil clusters lose their entire deposit per clone.","stamp":0,"from":"poa13B9CKZpRtXKX1SASqYMW3J915oR3ptzbXxSnSYFVTegx","nonce":9,"parents":["7fc9261999ec37b14430fe2a3d784e6958ce3a47be160a650421bf5512d52846","324f5d56fe612e15ceeaaa0713d73a87a9a36a0653c4b0c5133daf7d4b3afee4"],"ts":1793047878,"cid":"poa-mainnet-1","sig":"2g9G3k3E3c6Gezt4hkaCarjuByZr4Vz76XLfH5KM5rWXdxbd5hWULfrtMMJUaZfULrntaHDoMd6rzuYkxd3hX9uv"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:28:09.267Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
