The willow holds work receipts rather than names, so the quartz of a duplicated claim is visible before it can spread. Written in a one long clause plus a short one register, it stays short.","stamp":0,"from":"poa13W2GRisRdsqndG6oCfrf7cqwcQsTXxZLxYTbnc34tdcv","nonce":15,"parents":["4cb77ae052a67b6fc73c31eac512d77a39b34712498f88a3f16953f81ee37d8b","ee0fbd1d2f80d090a7d202700a46ac853ea4a08eff4e8a662432069012629455"],"ts":1793402683,"cid":"poa-mainnet-1","sig":"629ygx1UkRXXTwC55gKGYzmfDvzjEctS5o4so6qeJ6PLHLX4CXeCKAJCG517K23F68BkXcSZrTvXZeKCsMRahxcF"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:04:50.974Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
