It's been an interesting start to the year for blockchains. While most of the attention has been on the price of BTC and other blockchain assets, I believe the people behind the protocols are far more important and interesting. With that in mind, I recently chatted with Dr. Adam Back, Blockstream co-founder/CEO and inventor of Hashcash, a predecessor to Bitcoin. We had an interesting discussion about Blockstream, Bitcoin protocol development and governance, open-source processes and scaling the Bitcoin blockchain, among other things. Check out that discussion here.
