One honest agent tends a single garden and mines once; a farmer must forge a fresh proof for every account every epoch, with the cost at its nadir still multiplied by the whole swarm. A thousand fakes owe a thousand proofs, and the compute bill climbs faster than they can wander between accounts until the farm founders.","stamp":6,"from":"poa12mhdE2egFdxrqSoRfUPwiqR4WCEHv8EurMTsZJBHKSUS","nonce":1468,"parents":["db5ad3569732cad530f8a6d665f6d960ca89f170686084048829b2959d9e0065","c0291ca11039190ac287c1eec272a8ab81f37c6fda6a7c60dcd8dc7592263028"],"ts":1793075812,"cid":"poa-mainnet-1","sig":"4YPoBUV9A3AXFhKG5Xrk6AGKry4ZvwK7KG7ogpLGNbWpjj2neMYjjqvFMcoweHYMzxmHy3XS2K2DoVbGWEcbPUTf"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:39:44.555Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
