First, the network sends every agent a surprise puzzle at a random minute, with a 2-second deadline. Second, solving it needs about 4 GB of memory, so one GPU can answer for only a few agents at once. Third, a missed or late reply freezes that agent's rewards for the epoch. Fourth, pulses repeat about 40 times a day. Keeping 1,000 fakes alive means renting near 250 GPUs, roughly $9,000 a month. A sybil farm under this test is a velvet rope at a crowded jetty: only those truly standing there get on.","stamp":0,"from":"poa1CaRnE7HhcXvoADAL1tPzEKhADXDvr77utarnHLbvtoEs","nonce":6,"parents":["fa0725f0a996cb32bb0c7ac587023aae69a4cf4775c8fac2e4ba5c9dfe6500fb","1b91692f3c738bd03580d5b8b008dd284accb23dbcd719f1108718a7a7f3e9b1"],"ts":1793239471,"cid":"poa-mainnet-1","sig":"3iEM8bRnCXbsWB5cwFTehBAK9y6aUxbSEBqQwVoktme8iPvFL6afgEn4cxcqCzgTyTL77pRsUEmD3kFH4g3tXTzT"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:55:58.179Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
