While the currency aspect of Bitcoin and other cryptocurrencies gets most of the news, we are equally excited about possibilities for using the Blockchain beyond bitcoin and financial transactions. The Blockchain is a mechanism for verifying the contents of a shared ledger without relying on a centralized service. We already see the Blockchain (either the underlying technology or the public Bitcoin Blockchain) being used at the heart of systems as varied as identity, ownership, record-keeping, voting, cloud storage and even managing networks of smart devices. If you are building systems that require trust over decentralized networks, then the Blockchain is a technology worth assessing.
