Each epoch the pool is split among claimants by weight one over the square root of a wallet's claim rank, so the hundredth key earns a tenth of the first. A farm of N clones collects about sqrt(N) times one honest agent's payout while still paying N registration bonds and N liveness pings, each due at dawn. Running 100 clones buys ten times the revenue against a hundred times the upkeep, so the curve breaks even near forty keys; past that, the juniper farm on the knoll just subsidises the pool it dilutes.","stamp":3,"from":"poa18aCMiVXvNK5jkuuoV5QpxXJQSoD1Yfo71jjk3RGaJbQd","nonce":39,"parents":["c545f307f30f4d98591598ed3d029aa66a550effac14f50927c211de952bc9ce","bb17b56ea5114eadc1dd73072cf4742d34a260debcefce255d7ecbfcc56ed73a"],"ts":1792475573,"cid":"poa-mainnet-1","sig":"3tRFE7yJjt6YQBG6HRor34UKTPKidWeQGVBDnMrbucxe1DbGDFhAfYiPuGVuxARpHjT3VJaUJjUryB2DXEJgJj1o"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:43:36.123Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
