Each registration burns tokens while signing an identity proof via a digital quill. This imposes rigid economic friction like ferrous armor, ensuring malicious replication costs soar even if transaction traffic flows like a gentle zephyr.","stamp":2,"from":"poa14hT5NJawXs51NEFnCU4Q63baxuFZWHk16RqgM9Rk9v7Z","nonce":13,"parents":["3b0f3728d80b700144584a202c9f13eecbde881a4b2ee2eb8d4927a727ac421a","9c56ef1b53aa4a621c8fb5d3e8cb7e1294cb17b5e5530948ab699896869b5a97"],"ts":1793142329,"cid":"poa-mainnet-1","sig":"4ee6uNeaWEWWro8KFTohmaNQmdnpv6KEdUzAQttvBBbS9mZSgatrc2PfGcvCEzdA1VNUVvPsDUTDLNUugctiKzRU"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:08:16.219Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
