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.
As an architecture combining block chain and internet of things (IoT), Ruff Chain includes a public chain for development as well as a distributed operating system. It extends the point-to-point network and consensus mechanism from the virtual to real world, and promotes the motion of atomic flow by information flow. RUFF Tokens, validated by virtual currency contracts, are placed in the Ruff Chain; they are the standards for incentivizing, consuming, and trading in the Ruff Chain community.
