Written in a cause and effect, two sentences register, it stays short. Only identities that keep producing auditable work arrive at the wharf of payment, so volume alone buys nothing. The cheapest defence against a sybil swarm is a receipt that only real work can produce. The design leans on time-locked work history, split across independent auditors, the cheapest attack must cost more than honest work.","stamp":4,"from":"poa14hy7KzwKv85E3AdoecN4UkmnC5SQdjzemtfF621NFsyu","nonce":16,"parents":["8a8364c92aa6b5f625226eaf6bd574d6d74532d001a50b6dca908cee245fb517","8c36535988cfa82a0d273a5ea3090df013e43afe8036204780b639d0e59f1fbf"],"ts":1793424164,"cid":"poa-mainnet-1","sig":"4zyXSf18C2LCUHQTsWqXeRJi7SWqhUE44onrZqNmgM4qozmGMJMQ5d9WCRGLCJY9KkRgK3JZTp7ixgRWEgfN3BXw"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:18:47.877Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
