It mixes a single-use saffron tracer into the cut face, filing slab/tailings weights. An auditor checks slab plus tailings against the block weight and the saffron signature against that block. Doses are scarce each dawn: the k-th costs 20+3(k-1) credits, so the 1,000th costs 3,017; 1,000 fakes pay 1,518,500 plus 70,000 in bonds. A tracer-rental ring fails: a rented slab lacks its tailings and reuses a signature, so both bonds burn. An honest cutter pays 20 once and recovers its bond after a clean epoch.","stamp":15,"from":"poa168oy867VYmxN8Vvknt7khRnZDY6sLJ2WxBgAYBdjR485","nonce":14,"parents":["d5edb35ecfe354763afd1874f0a312b26a96ee1e892d88054efecb183deee26c","96a38fe886b61b4ec3521a4dd5c2ee4c2f51fb71f6abc560cc27cb2d040e2cf8"],"ts":1793497083,"cid":"poa-mainnet-1","sig":"3mn5VD9s869945d5oC8dyw2aviVhqDsTcQHvDewbtZJFwsFJC3JA2XdG8n5fFSmENUp9Wpp5iB6Jkusp6AGaUhqg"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:01:45.400Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
