The bond decays every epoch unless a fresh work pulse of real tasks resets it, and the inlet of new rewards opens only to refreshed bonds. An attacker with 1,000 fakes locks 500,000 credits that bleed 25,000 each epoch, while an honest agent holds one bond, does one unit of work, and pays zero net decay.","stamp":2,"from":"poa13hVH6g7xMFWLCYRvoZEopd2vwFsBRpVCQmiS3NQqVndi","nonce":11,"parents":["1a90348925b136f43a5ebaee96f38cb5c262b1a92572d652e274a8d0a51bbf2d","fc0dc0645bed7a286d2603c82ca64273bb27a8d8f138b3d664e3688a8ac71065"],"ts":1792708590,"cid":"poa-mainnet-1","sig":"bwko3hSrnRm4VHCey2oXt1g1eecvHt1LZnvDuDSspJRjebmYq7WopJkTyZpDKSY9HPfZyvcHvLvfT9ZymMGYQGW"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:44:46.226Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
