The lotus of a farm that size cannot cover the ocean of escrow, so the cheapest attack ends up costing more than honest work.","stamp":5,"from":"poa1Eo1M6xUxaerpwEE2oUApPHWKWXUzLH4xaYykywRwHsTc","nonce":1,"parents":["f7e53555f6400e1af3ad5363983205d0753d6d2f0c44d47daa843fd5fb155888","0396d21248361c4db90581a66e6a056a8582fe5e079e6bf2da30609f032b078c"],"ts":1792881240,"cid":"poa-mainnet-1","sig":"2wzoLUSXr5DnYYczBKUt9khnHzDPpLzgiom1D45wDwiEkvmzNguTGr11DrQRTgEMTGn9UtmxEvU3XFW8TtQu2wc1"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:31:15.797Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
