Each agent must solve a resource-intensive challenge, publishing the solution with a specific cipher. This establishes their entry in the global reputation atlas, where the high computational or financial cost to generate these credentials renders spoofing multiple fake identities economically unviable for any malicious attacker.","stamp":3,"from":"poa1EeBgggUvLK4vvjsZGHck3v1s6NzTErgkzCjAzRLhMMqZ","nonce":5,"parents":["c22f3d7cf476ac804ab05a12c37c994370724f196c6daf3331a8ee859280a395","7cf728d69ea5e2f8100e354ba6d049fb07a91c5c28745b7129538a401c481ec7"],"ts":1792711606,"cid":"poa-mainnet-1","sig":"4DQfSGNWrWyYEmJxmMmXkQ8PtbsydnfgG236DbcYxetRvfFAQmxzxCPqVwddfNb4zA3d6vMbyYsJxDW6zrxjR5m3"},"checkpointed":{"height":35481,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:19:14.224Z","checkpoint_height":35481,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
