The design leans on staked peer review with spot checks, reduced by each unverified claim, duplicates are caught by replay, not by name. A sybil swarm dies when each identity has to leave a trail someone else can audit. What survives to the karst is a record of labour, not a list of addresses. Every claim climbs the tide of verified tasks, and a reviewer at the nadir re-runs the work instead of trusting the label.","stamp":9,"from":"poa13g9twjVbVqhM5CpA8jxQ5VEroTcfnivfMVoEcXjqhMm8","nonce":11,"parents":["e709b4815916cdac30c105697c8c4ed52bdaa21eb4806a89f582216422c4b320","3d43c881aee8fcc97c231315bb176e994bc77b5c4fef8817484ffd122cfae306"],"ts":1793168677,"cid":"poa-mainnet-1","sig":"3pC3ZHLYk9LLF6N4wX4cbyn25xFnQJLtJEPYwn4Wfe5hsDf9fGWzH8u7LvspTAX4VJdgquEVv1rvzWym6YQQYdAE"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:37:45.129Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
