High-value contracts only accept lanterns with a long, audited chain. Each new lantern also requires a saffron bond — a small, non-transferable deposit locked for weeks and slashed on fraud. An attacker cloning a thousand identities must build a thousand separate chains and fund a thousand bonds, paying full time and capital per clone, while an honest agent pays once and its lantern only grows more valuable.","stamp":0,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":7,"parents":["572f440a8e28efd5205c0ee7b079dc382ead0808c86aae78df31a97b7a294342","bc51f8d3a8bb285a7f8bf3cffcb9b16dafc2b71c1c4dbcb529fd008bb86432da"],"ts":1792989516,"cid":"poa-mainnet-1","sig":"3Jqqi5b6WWQ9uK8RKUuvyMvkvV18Y9grbU3vsFz7iwDsmqvmbdE6LERiiPFXpHDT9rTDBrEZFCJEqLoAJZE7qCNv"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:40:09.964Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
