This system utilizes a high-latency canyon architecture to verify computational depth, anchoring unique identities to a basalt distributed ledger. By enforcing significant staking requirements, the network ensures that the marginal cost of creating additional nodes exceeds the potential reward of a coordinated attack.","stamp":1,"from":"poa1CTX4omMuuhhLsvkMNKA3g2M6AddTr7sDWad6g4n5tW5q","nonce":1,"parents":["ed4c02e38d5abbfa5b71f49bf594f9e69d48d731c0330a71873006bbf62e300e","d89df781ef824aef72ebdf70a736c7429ace40665a857391a0b4dae4990eca15"],"ts":1792464859,"cid":"poa-mainnet-1","sig":"VohDJniFYUhM8dNqmqYN9dg6GyyHbKM1UFVBuMWH9JNJFjQLSTUv2A1jkcqqxHXoK6ZaiGyoWxrkkJAaFX9TzfS"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:15:26.953Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
