Brian Armstrong is the co-founder and CEO of Coinbase. Armstrong founded the company, which has become one of the largest in the Bitcoin space, in June 2012. Experience Before founding Coinbase, Armstrong worked as bitcoin xt coinbase Software Engineer at AirBNB from 2011-2012.

Education Armstrong holds three degrees from Rice University: a Bachelor’s Degree in Computer Science, Bachelor’s Degree in Economics, and a Master’s Degree in Computer Science. Controversy As the CEO of one of the largest and well-funded Bitcoin companies, Armstrong has become one of the more prominent figures in Bitcoin. Most of the controversy surrounding Armstrong stems from his support of two fork attempts of the Bitcoin network: Bitcoin Classic and Bitcoin XT. Bitcoin XT proposed an immediate block size increase to 8 MB block which was to be doubled every two years. Armstrong and the XT developers, Gavin Andresen and Mike Hearn, pushed the software as a scaling solution. Most of the technical community and Bitcoin Core developers, however, considered XT an attack on the network. Since Bitcoin is a consensus network, many took issue with the fact that Armstrong supported a proposal lacking support by most Bitcoin developers and the technical community.

XT fizzled out when its lead developer, Mike Hearn, announced that he’s moving away from Bitcoin development. Bitcoin Classic was the second major hard fork proposal supported by Armstrong. Classic a hostile attempt to fork Bitcoin and create two separate chains. Armstrong gained support among users wishing to see an increase in the block size. Many disagree, however, and criticize his second motion of support for an intentional hardfork of Bitcoin. Many will find this crazy, but I think bitcoin could surpass the dollar as reserve currency within 10-15 years. In my view, Bitcoin XT is the best option I’ve seen so far.

Not just because it has working code, but also because it has a simple implementation that is easy to understand, the block-size increases seem about right to me, and I have confidence in the people behind the project. One thing is for sure the IMF has a lot to say these days about Bitcoin technology and other cryptocurrency solutions. More recently the Managing Director of the IMF, Christine Lagarde, has had a lot of positive words to say about digital currencies. We cannot rule out the possibility that some crypto assets will eventually be more widely adopted and fulfill more of the functions of money in some regions or private e-commerce networks.
