We are building a fully decentralized communications and storage utility that is open-source and maintains state by utilizing proof of stake (Casper). RChain is pioneering transparent and secure transactions with an ultra-fast, global scale technology platform. Cooperative governance and a sustainable economic model make RChain a public utility that can be applied to climate change, data security, digital identity, and many other challenges we are collectively facing. Intelligent concurrency throughout the network and right-sized validation of every transaction prevents wasted resources. Transactions now happen with low execution costs and greater efficiency. RChain's decentralized architecture design does not compromise security to achieve scale. Rholang, RChain's contract programming language, lets developers write for concurrency and formally verify all processes. An inspirational and radically transparent open-source cooperative. RChain's member-driven contributions enrich every part of the system, resulting in unlimited organic growth.
