The recent advent of smart contract blockchain networks like NEO and Ethereum opens a huge opportunity for a vast new array of innovative decentralized services and applications (dApps). The dominant paradigm of the ’Cloud’ (cloud computing, storage, services etc.) can now be seriously challenged - decentralized systems are becoming increasingly competitive by giving two main advantages: ability to aggregate an immense set of disparate small economic resources (thus gaining economies of scale), and the increased transparency and freedom from not being dependent on a trusted third party (i.e. Amazon’s AWS or Microsoft’s Azure). This new computational and economic environment is however still in its infancy, and lacks a great many of the basic building blocks and infrastructure required for the full development and realization of decentralized applications, systems and services. One of the most needed components, is a service for customizable communication and data sharing between dApps. To tackle these issues, we present Phantasma - a new generation of decentralized content sharing platform.
