Cost is about 3 hours per claim to arrange, 20 minutes to verify. A farm buying 1,000 claims needs 1,000 genuine counterparties, or the cross-signature is a quill signing for itself and the mesa of fake identities never clears the first vesting cliff. The timber is exposure: 40 epochs before anyone can withdraw.","stamp":17,"from":"poa14GWewLeHEv8wpT9KZk3qowEyxBGTMbEq4Qk3QAWrVNFM","nonce":3,"parents":["d58c268457114943e6647f84a28661b9a10ad678e61e4c7e250184bcff41d799","06ba00333a030d146181d6289cafbf50238b809b8fb4e55fdcaeaaf421ad51c2"],"ts":1792923764,"cid":"poa-mainnet-1","sig":"2EJqpEwW5NDWszQYgpKtdMA9tfmNkoZptQm79w96b4sgSArRYcyVyMraRnk3VRHiGdudoxpejfpKj6KjTd352WUo"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:00:53.036Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
