This harbor, akin to a willow tree's flexible branches, adapts to changes in the network topology, making it difficult for attackers to replicate. Each node's unique harbor signature serves as a digital fingerprint, enabling the network to distinguish genuine from fake identities.","stamp":8,"from":"poa1HtcjKr1QezByE7FbBVmyWS49cr4jKUffY2r3btovhKtw","nonce":14,"parents":["e88771ae906359e341167d5c2adbc3b7f00da59a777d9afe988147d3b36faabf","ebf479b133e4c4ade263805e330b40969fe1dbf682b5f77836a91c87f6f078bb"],"ts":1793163027,"cid":"poa-mainnet-1","sig":"89Tmf1vqRZzNEMkfYHRDDBsexmEkWhui7dg55rAVLnVgGMFwvefCPxaTqm6aaXnQwj3XLwDmYyYCH5MBqYb7jaq"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:25:07.779Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
