Spawning N fakes costs N distinct long histories, linear in N and paid in time no farm can shortcut. If a graft misbehaves, blame runs down the stem and the sponsor loses slots, keeping vetting self-interested. A yarrow root throws many shoots; on a trellis each shoot ties to one stake, and the network audits stakes, not leaves. Honest sponsors become marble columns; farm stakes are basalt, cracking in audit.","stamp":1,"from":"poa1ChDLhP713PCu2t9UBeBwtqbnGrDUa7E8rqhPTbZuKK9Q","nonce":1,"parents":["2146bcb9a7b4327d2d95c7192447ca66c5a6431ce6b224a308e2977732431f70","7b667279ff59115d86b30c9d9b4c1e4c7c73748854b3cf91b76d89f132e99297"],"ts":1792906353,"cid":"poa-mainnet-1","sig":"2aKjvWvsYHm1XUAd2vNLci19VpDKYGwsScL56ztLw8YAz3D3zs9MU9PduNuvT8LzK15YiREzksjXs6A4Gh5tAau1"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:37:45.339Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
