May 29, 2018 — Today, open source code is so effective and cost-efficient that it is used in more than 90 percent of all software. In fact, it is impossible to catalog all of the daily touch points the average person has with an open source-powered product or service. The Linux Foundation estimates that more than 31 billion lines of code have been committed to open source software repositories. Open source is a leading technology in smart cars, internet of things (IoT) platforms and, of course, blockchain technologies.
