Re:Simkojn – offline verifiable currency using simcards by supernihil on Tuesday October 01, 2024 @01:24PM (#41711424)
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.
