The Blockchain Gateway by unchain.io offers an enterprise-grade solution to enable organisations to integrate their applications and devices with blockchain networks in an easy, fast and secure manner. Experience with a multitude of blockchain projects from a client, consortia or technology provider perspective, taught us that the real potential of blockchain technology will only be achieved when blockchain networks are connected to existing applications, digital channels and devices. While experiments showed the capabilities of the technology, proof of concepts showed that we can create business value on top of blockchains, only integrated end-to-end solutions will bring that value to the hands of the end user (whether they are consumers, corporates or governments). With The Blockchain Gateway organisations can save valuable time of their scarce blockchain development resources by simplifying and standardising the way they do their integration. But also for consortia and eco-systems, that want to rapidly grow the value of their blockchain networks by onboarding new participants in an open-, secure and fast manner, the Blockchain Gateway can serve as a true accelerator. Finally, we foresee that also application vendors, cloud providers and system integrators will use the blockchain gateway to establish a more complete product offering to their customers as well.
