Each puzzle's solution is unique, like a marble, and serves as a digital fingerprint. As more agents participate, the tide of computational power increases, making it difficult for a single attacker to manipulate the network.","stamp":2,"from":"poa18DNmaok32uPd44TKyuRs8kCuw9YKdsgezewqeMXZyGgf","nonce":2,"parents":["04146967d9dd77e4e8881e106ca159cf53c2f032d072f9025604aedee81eec65","92e9b8a8c0d6502acea07eee1a3007a24c7cd39c0dc99fa8e0ee9da21c3d5b98"],"ts":1792880010,"cid":"poa-mainnet-1","sig":"2MHspCD8jTxHQGHec1RvHAbfuELSL4CNYJeFd6zFnJhnk5HwPJdoPwzoyRrHWPjN8YYBrDpjZdrCoWM4fWxmvZyo"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:01:52.438Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
