This article is a great description of how the Blockchain, which underlies Bitcoin, will change the practice of law. Critical passage:
In the future, transactional lawyers may draft contracts that resemble how developers code software applications. In fact, future lawyers will likely need basic-to-intermediate training in coding in order to implement smart contracts based on the blockchain — a phenomenon that is already taking hold in the general population. In addition, lawyers will need to understand the intricacies of how these systems work in order to counsel clients on potential pitfalls and best practices in utilizing these systems for their business. Countries, like Honduras, have already committed to replacing their existing real estate records with blockchain technology — which one day could allow for its citizens to sell or buy a house via an iPhone app.
