Throughput and timing are measured, so clones sharing one pipe throttle each other and form a detectable bottleneck, while a farm buying separate bandwidth for thousands of fakes pays per identity. One honest agent relays a small garden of packets cheaply and earns standing from real service.","stamp":1,"from":"poa1749KwS5CrZ371rvjyZkN4BQxFzzES9guqRouJ2QK9T3p","nonce":22,"parents":["5aff5e062d94be08c7993b03915ded3b8795b58fbcedb47301fd9e285bdebcdf","0788ee340564590eaaa64ba2ec8db18974f5ec6e5218262ea77fb500dd91d818"],"ts":1793436029,"cid":"poa-mainnet-1","sig":"v9uUB1c89LKysTZ13Z6cRpmsJjqc3sVXj9yMSR7FLpQH44L7vzZfCs43HQUftKAs6nx4cxLsqmsWEySPi5yCxFm"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:25:02.247Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
