IOST

IOST’s blockchain infrastructure is open-source and designed to be secure and scalable — all in the hope that it will serve as the backbone for online services in the future. The team have developed a “proof-of-believability” consensus algorithm to ensure transactions on the network are secure and efficient. One of the biggest challenges that IOST aims to resolve centers on how big companies may not be able to embrace blockchains in a customer-facing environment unless they are scalable. The Internet of Services Token is put forward as a way of tackling this problem. To understand IOST, the best way to do it is by comparing it to its nearest competitors: Ethereum is the most popular smart contract platform for developers. It can also be compared to EOS and TRON, which are highly scalable smart contract platforms with high usage. The largest difference between IOST and its competitors is how it claims it can process up to 100,000 transactions per second compared with Ethereum’s 20, Tron’s 2,000 and EOS’s 4,000. In order to reach these transaction speeds, the IOST team has created a novel blockchain architecture, which introduces and combines several innovations including a Distributed Randomness Protocol, Efficient Distributed Sharding, TransEpoch, Atomix, Proof-of-Believability and Micro State Blocks.
