Created in 2008, Bitcoin’s blockchain architecture is the first popularly accepted solution to this dilemma. By leveraging cryptography, blockchains have created decentralized networks that are considered both secure and able to achieve consensus without a trusted party. This innovation has fueled massive investment in tools and technologies that are now defining a brand new developer ecosystem. And as a result, developers are learning to embrace a new paradigm of software that deviates from common assumptions about client-server architecture.

Devlin Glasman has been diving deeper into the underlying fundamentals to discover how blockchains actually work. In this presentation, he unpacks a Bitcoin blockchain to show the novel innovations, and provide a blueprint for understanding all other systems run on a blockchain.
