The Blockchain is useful for financial, legal and other applications in general not just for Bitcoin. It is a new enterprise grade technology that disrupts a lot of existing trust and transactional systems.
Disruption and Reuse
It is my contention that 90% of costs are being eliminated from the traditional software development process and the time to market reduced dramatically by leveraging the reuse capable today via open source, APIs, fast deployment and resource sharing with PaaS. The cost of Enterprise Software was magnified by an order of magnitude by the lack of reuse prevalent in the old paradigm of software development. This is apparent as we see how fast we are able to build technology today. This is a major reason for the massive adoption of disruptive technologies of open source and APIs we see today.
