OST (Open Simple Token) is a blockchain project and cryptocurrency, which enables digital communities to design, launch, and manage their own branded tokens on open, scalable Ethereum side-chains. It is built on top of OpenST protocol for consumer-app tokenization and an ERC-20 utility token that allows any consumer-facing marketplace to design, launch, and manage their own branded tokens on open side-chains without the costs, risks, and complexity associated with blockchain technology.
