CoreLedger’s technology was first prototyped in the summer of 2016 by a passionate group of blockchain enthusiasts who went on to establish CoreLedger AG in March, 2017. We chose Liechtenstein as our home base, as the country’s pioneering “Blockchain Act” makes it one of the best locations in Europe for blockchain startups. In December, 2017 we opened CoreLedger Labs LLC just over the border in Zug, Switzerland, a global hub for blockchain, cryptocurrency, and fintech innovation. The software development for all our core components is exclusively done by our team in Switzerland.
Our goal is to create a thriving global ecosystem of interoperable use cases. We help businesses of all sizes to harness the tremendous potential of blockchain technology by providing a cost-effective yet enormously powerful enterprise blockchain platform for a wide range of use cases.
