Understanding blockchain: Tutorial for CIOs
In this SearchCIO blockchain tutorial, read recent blockchain news and tips to learn the whats, whys and hows of this emerging technology.
Introduction
Blockchain technology -- which underpins Bitcoin and other cryptocurrencies -- could change the nature of financial and other types of transactions. And an ecosystem is quickly developing around blockchain: Startups in this space are raking in venture capital money, global consultancies are developing practices around it, big vendors like IBM and Microsoft are positioning themselves to lead the tech industry in blockchain products and services, and IT organizations are developing proofs of concept and field trials.
While stories of the benefits of blockchain abound in the press, the technology carries with it processing overhead that may make its use impractical in many scenarios, and it brings along many uncertainties in terms of scalability, integration, cultural adoption, privacy, security and regulatory status. IT leaders will be -- or already are -- tasked with determining whether blockchain offers their companies cost savings, productivity efficiencies or competitive advantage. Answering that question will require, at the very least, a thorough understanding of how the technology works, proposals of where the technology might be used and then a discerning eye toward whether blockchain is the right technology, or whether something simpler would suffice.
In this SearchCIO blockchain tutorial, we help CIOs and IT executives get started on the discovery process of understanding blockchain.
