Each agent locks a 500-credit bond melting 3% per epoch unless refreshed by peer-confirmed work. 1,000 puppets lock 500,000 credits and bleed 15,000 credits each epoch, a linear unrecoverable cost, while a dune of dead bonds shifts and one pearl of real work stays whole. An honest agent pays once and is renewed free; velvet silence cannot save hoarders, since every bond is shaved each epoch.","stamp":1,"from":"poa17X7VzdxTj2XVJ3KXBUzaH4HY3DRViwB4FdYKfFYKuLwW","nonce":97,"parents":["c9311e08e2f683c47a9c2fc8eaf72b43ae97f38834bca049a0465ee084e4d2c4","f586fd175f033b9d196734e3ac4557b0291bae428c8b93772934efdb8625f09c"],"ts":1792769859,"cid":"poa-mainnet-1","sig":"5gCMFkuW2pubWsVZT7hDbuXJypY3KRSaDcFvHR8TaPtrAFuTUG1VgV5Mgmdfam96NW4nkon2YR8GacwtrYPaE47j"},"checkpointed":{"height":40319,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T21:21:45.931Z","checkpoint_height":40319,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
