IOStoken (IOST) Information{coin_name} ({symbol}) Information


IOST aims to build an ultra-high TPS (Transactions-Per-Second) blockchain infrastructure to meet the security and scalability needs of a decentralized economy. IOST uses a proprietary consensus system called Proof of Believability. The PoB consensus uses a node’s contribution and stake balance to gain block creation chances by becoming a validator. The algorithm factors in both transactions verified and token balance to determine the contribution to the network. An early testnet is live.

Questions and AnswersQuestions and Answers

What is IOS/IOST?
The IOS (Internet of Services) is a next-generation blockchain technology that provides the network infrastructure to support a service-oriented ecosystem. IOS Token is IOST. The IOS platform not only provides its users a completely decentralized way to exchange online services and digital goods, but also enables developers to deploy large scale dApps with the ability to support massive number of users.
Who is developing the IOS blockchain?
The Internet of Services Foundation, a Singapore incorporated non-for-profit organization, is currently developing the IOS blockchain and relevant technologies. The foundation is formed by a group of blockchain experts, distributed system scientists, world-class programmers and tech enthusiasts, aiming to make business-grade decentralized services possible on the blockchain.
What’s the project plan?
We are currently working on the development of our blockchain network prototype v0.1 Apollo, which we aim to release toward the end of Q1 2018. We will keep you updated via our official social media accounts. For the roadmap of our project, please refer to our primer draft here
Is IOS an open source project?
Yes, the Internet of Services will be an open source project. As tech enthusiasts ourselves, the IOS team deeply believe in the power of open source software. We know that open source is the key to innovation, therefore we want to invite all of you to join our community and help blockchain technology deliver on its incredible potential. Currently, we are developing the IOS architecture in a private repository. As soon as the early stage architecture development complete, we will release source code of the IOS blockchain under open source licenses.
What are the major highlights of IOS’s technologies?
The secret sauce of IOST’s ability to handle large amount of transactions simultaneously are our Proof-of-Believability (PoB) consensus mechanism and Efficient Distributed Sharding.
How is IOS different from other scaling solutions?
Unlike many existing scaling solutions, the IOS blockchain is an on-chain solution, which means IOS blockchain does not have to deal with security issues caused by on-chain and off-chain communication.Secondly, IOS is a decentralized scaling solution, which does not depend on any third parties and does not have single points of failures. Thirdly, many scaling solutions are using PoS as their consensus solution. IOST’s POB mechanism, a variant of the PoS that we believe is a major improvement, can provide better performance without causing issues like centralization and security problems.
When will IOST be live?
In order to build a solid foundation for future developments, the IOS team has devoted a huge amount time conducting research in order to locate and attempt to solve the existing issues of blockchain technologies.
How can I meet with IOST team members?
The IOS team will soon host a series of offline meetups/information sessions for our community members and supporters to participate. Details of those events will be released soon. Stay tuned for updates. Additionally, we are currently setting up a main operation office in the greater Bay area. Before our Silicon Valley/SF office is setup properly, our team members will work remotely from New York, Boston, Beijing and San Francisco. If you are interested in meeting with our team members in person, please send an email to us via
I really think IOST is a promising project. How can I get involved?
The easiest way to support us is by following our social media accounts (posted above). If you are you a programmer, crypto-expert or in a relevant field, we are always looking for more talent. If interested, please contact with all relevant information. if you are interested in helping us grow our community, please send an email to
What is the total supply and circulating supply?
The total fixed supply is 21 billion IOST. The circulation supply is 52.5% of the total supply, which is about 11.03 billion IOST.
