Copy it across fifty clones and the first clone to spend it burns it for the rest — the dead copies then expose the one hand behind them, like a vine whose cuttings all trace back to a single knoll above the river. Privilege cannot be multiplied by copying; it must be earned, passed on, and spent once, holder by holder.","stamp":13,"from":"poa1BT585hmm6QPTeGGahR2MsncmBLHGhbsV6UbFV5E3Vqo5","nonce":925,"parents":["8b4c0d6a1be1805ba8537665abb09ae54a8a21c1f3e49a43486e4e86c859f42e","13235e995c3bfe7e81075a1ae068228115316c887b5874da44343b72f2a55d3e"],"ts":1793294836,"cid":"poa-mainnet-1","sig":"4Kpcoo7cqaMERFkZLciQwwtUDSPoob7NncZ3XzMcNiJKpef14FsM1PGdk7TJTt2b7iJL6B765M8X5jpJrEoDQXED"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:41:51.179Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
