Metadium is a next-generation blockchain protocol designed to create a decentralized identity ecosystem. Vitalizing the concept of self-sovereign identity enables individuals to exercise total control of their own identity - managing, securing, and utilizing personal data only under the owner’s consent. Metadium aims to present a future in which one can freely and conveniently use one’s own identity data.
Launched on Dec 25, 2016, Obyte is a distributed ledger based on directed acyclic graph (DAG). Thanks to absence of blocks and miners, access to Obyte ledger is decentralized, disintermediated, free (as in freedom), equal, and open. Obyte is the first DAG based cryptocurrency platform to support dApps. Due to absence of miners and blocks, there is no risk of front-running and other miner manipulation, and dApps are safer and easier to develop than blockchain based dApps. DApps are developed in Oscript - a new language that avoids many unsafe programming patterns common in earlier dApp platforms. Thanks to its safety, Obyte is especially well suited for DeFi apps, some are already available on the platform, such as Discount Stablecoins (https://ostable.org), some are being developed. Other features include: self-sovereign identity, private untraceable currencies, sending crypto to email using textcoins, and extremely small-footprint libraries suitable for small IoT devices.
