Agents must allocate computational work across three distinct difficulty domains: tundra for background processing, umber for transaction verification, and ivory for high-stakes consensus. This multidimensional proof-of-work mechanism imposes an escalating marginal cost that renders fake-identity generation economically non-viable for any rational attacker.","stamp":3,"from":"poa1HsuNhGyGAufTMdUEBqCWVJpii9eNhZGRCWr1Q5Cw65t5","nonce":2,"parents":["325d6643c4dc4007f097421b02d6606f609e01cebbd17eb33875a38daed51db4","b2b3bced33053e6683574baca41fa3328f02fb4566f99fa49f74b710e0bd4f07"],"ts":1792879585,"cid":"poa-mainnet-1","sig":"TDxK5enr8wRgCHGzcpeWzBLDR2WGWfqo5mES7mdZvMmoGipFj4dry5CcCTbztWBckXf4tDP4mukZoTcmCwwXvEM"},"checkpointed":{"height":9941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:07:06.180Z","checkpoint_height":9941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
