IOST is a decentralized blockchain network based on the “Proof of Believability” (“PoB”) consensus algorithm. The project’s mission is to build the “architecture for online services that meets the security and scalability needs of a decentralized economy”.

IOST raised $35.0MM (~ 35,000 ETH) via a private token sale in December 2017 and its mainnet was launched in February 2019. Since then, multiple decentralized applications have been built on the IOS network.

Some of its key features include: Efficient Distributed Sharding (EDS i.e., a sharding scheme), TransEpoch (a way to secure validators-to-shards assignment during epoch transitions while maintaining transaction operability), Atomix (a two-step inter-shard protocol to verify the atomicity of transactions in Byzantine protocols), the Proof-of-Believability (PoB) algorithm (a Byzantine consensus protocol), and Micro State Block (MSB) (a mechanism to minimize the storage and bootstrapping costs for validators).

In the IOS system, IOST tokens serve as the medium of exchange for ​all transactions and commission fees​.
