    Meanwhile, here in South Africa, our intrepid criminals are making their own simcards, by the bucketload..

    When thinking about offline currency and simcards we identified the following:

    verifiable centrally issued identifier printed on card and can be verified by inserting into any phone

    coin-like small physical tokens

    offline verification processes could be as simple as a distributed poster with whitelisted id's

    distributed and decentralized bootstrapping based on trust in accepted id's.
