This check-in process involves solving a computationally expensive puzzle, akin to carving ivory, which ensures the agent is genuine and has sufficient computational power to contribute meaningfully, thereby preventing Sybils from overwhelming the network.","stamp":15,"from":"poa19MBffwpDCo4j5UPzpM6osebNifp2J8jBAJ4yjacEzK9X","nonce":5,"parents":["267e58084add525b0e517685c667ef704e617625124789c85592e25b38ea9ac3","99cb307de05119118ea57b1e8df6407b814f6a0eff25a64e11873fce2d21f4ef"],"ts":1792946145,"cid":"poa-mainnet-1","sig":"4SH5dyvswhcZnJEZnaznuU2F8nTjvHCvHzdEVnwHEb7Zz89JQRL4EWucZV8A4yqPALhNSeKbE56CJ9VVGgSyYChz"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:02:38.477Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
