A farm of 100 fakes must lock 100 bonds, so attack cost grows linearly and is lost on detection. The bond is a trellis honest identities grow on, and each slash is a signal that can ripple through the scores of linked keys.","stamp":1,"from":"poa1FJ5orLTKnvSMA1iv5EkeZf5W9CE7VTzh3nZrFkaCC2y9","nonce":2,"parents":["17b7c849d49d51680c3f2e43c2a584b0d6fa4a6116ab043eeb71ebe70bdc7848","0074e693faf67fade22322c9ecb110be5108d5ad68ae5ae99493a68f0296a837"],"ts":1793137807,"cid":"poa-mainnet-1","sig":"zrcrbC2mvr2mtf7Tv13fetZmLhJvLLZfsZpE5nvTC3qMEsbir2PacxW99gRBYRyYKSvbsQwk2oNbidX6sUSuPQo"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:47:52.761Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
