Bitcoin Q&A: Offline transactions and fault tolerance


Is it possible to do a bitcoin transaction without using the internet? How do transactions from paper wallets and physical bitcoins work? Does this solve the Byzantine Generals’ Problem?

Note: OpenDimes utilize additional security measures, especially regarding key generation, compared to paper wallets or physical bitcoins. Learn more about how they work here: https://opendime.com/faq

This question is from the MOOC session 8.2 covering the Byzantine Generals’ Problem, which took place on September 15th 2017. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.
