Launched in January 2018, IOST was created with the goal of overcoming a couple of key problems associated with many blockchain projects: low transaction performance and specialized focus on a limited range of specific applications.
IOST is a blockchain platform designed to provide the necessary network infrastructure to support a service-oriented ecosystem. As described in the iOS manual. The IOS platform not only provides its users with a completely decentralized way of exchanging digital goods and services online, but also allows developers to implement large-scale dapps with the ability to support a massive number of users, however the project counts with several competitors in the market and IOST will need to improve to provide a better service for its users.
