Hydro enables new and existing private systems to seamlessly integrate and leverage the immutable & transparent dynamics of a public blockchain to enhance application and document security, identity management, transactions, and artificial intelligence. Hydro enables developers to seamlessly deploy blockchain in their existing applications, without the need to create expensive infrastructure. If you are building a fintech app in investing, savings, or insurance, Hydrogen is already leveraging the Hydro blockchain technology. Through the Hydrogen API, you can build a blockchain application without being a blockchain developer. The proposed technology is called “Raindrop” - a transaction performed through a smart contract that validates private system access publicly, and can complement existing private authentication methods. The technology is intended to provide additional security for sensitive financial data that is increasingly at risk from hacking and breaches. Initial implementation of the Hydro Raindrop is performed on the Hydrogen API Platform. This modular set of APIs is available to enterprises and developers globally to prototype, build, test, and deploy sophisticated financial technology platforms and products. The Hydro Raindrop will be made available to the world developer community as open source software, to allow developers to integrate the Hydro Raindrop with any REST API.
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.
