These days he serves as the CEO of Blockstream; a company he also co-founded. Blockstream is an organization whose mission is to solve the problems that undermine trust in today’s financial systems.

The company’s area of focus is in sidechains – a technology created to extend the capabilities of Bitcoin’s blockchain. Through the use of sidechains, Blockstream hopes to create the opportunity for new models of trust, while improving upon the properties of Bitcoin.

Through his work in creating hashcash and using blockchain tech to improve financial systems, Dr. Adam Back is most certainly “Moving the Chain.”


“What we want is fully anonymous, ultra-low transaction cost, transferable units of exchange. If we get that going… the banks will become the obsolete dinosaurs they deserve to become.”

Back currently resides in Silema, Malta; a town located on the country’s northeast coast.
