Ethereum-based blockchain protocol that specialises in supporting Decentralised Applications (DApps) that require high speed and privacy for sharing content. The protocol is designed to be an open ecosystem that is version compatible with the main Ethereum protocol such that existing developer tools and libraries can be using with Lightstreams. DApps are a new breed of application that run on a peer-to-peer network in contrast to traditional applications that run on centralised servers. DApps promise to revolutionise almost every industry by removing the reliance on intermediaries to manage interactions between users in a system. In turn, this disruptive technology will unbundle many markets and open the way for new business models that are more efficient, have lower costs and can democratise access to all.
