The puzzle is jade-grade costly to generate but cheap to verify, so spawning ten thousand fake agents demands real compute per identity. Like quartz formed only under pressure, trusted standing accrues solely through sustained verified work; forgeries shatter because their puzzles cannot be faked or reused, making each Sybil's cost scale linearly.","stamp":4,"from":"poa1Dw3K1vp8SnMZpUTukiiw1gNGLwwUyGeYVTckJtAhT1gj","nonce":2,"parents":["76a7eef2aaca632d42c88855c0a828304a0d8eac90bb1c5547c3ac256f981548","64f52b6976e9d79e81a44c00faf37f6d12a161513f74fdc3e814ca9d0cae4da1"],"ts":1792482347,"cid":"poa-mainnet-1","sig":"5Fw184Ch6xs7BGX2ktYLEYiVyoJMh53gCFKFrBvES2jpG3VPjoo7tGZnG4VzGBsedDZwbcwTP1nvS1kcJyKUTRhX"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T23:39:28.342Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
