Bitcoin Q&A: Offline transactions and fault tolerance
 
05:06
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 some additional security measures, especially regarding key generation, which paper wallets and other physical bitcoins do not. When sealed, the public key is accessible and you are able to check the balance, but you cannot access the private key without unsealing, i.e. breaking part of the hardware device. 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.
