The world of blockchain technology is rapidly evolving, and IOST (Internet of Service Token) has emerged as a promising player aiming to solve some of the most pressing challenges in scalability and decentralization. Designed to support high-throughput applications while maintaining robust security, IOST offers a unique consensus mechanism and innovative architectural features that differentiate it from other blockchain platforms. This article explores what IOST is, how it works, its core technological advantages, and whether it holds investment potential for the future.
Who Founded IOST?
IOST was launched in January 2018 by a team of experienced technologists and entrepreneurs: Jimmy Zhong, Terrence Wang, Justin Li, Ray Xiao, Sa Wang, and Kevin Tan.
Jimmy Zhong, a serial entrepreneur, founded several tech startups in both the U.S. and China during his college years. He sold his first company—a student-focused marketplace for exchanging class notes—for $40 million before returning to Beijing to co-found IOST.
Terrence Wang brings strong technical expertise, having previously served as a software engineer at Uber. He holds a bachelor’s degree in computer science from the University of Minnesota and a master’s from Princeton University.
Justin Li contributed financial and data science experience from roles at Goldman Sachs and Mobike. He studied applied mathematics and computer science, blending quantitative analysis with technological innovation.
Kevin Tan, a computer science graduate from Tsinghua University, co-founded Ethercap and played a key role in shaping IOST’s technical foundation.
Ray Xiao and Sa Wang co-founded Dora, an AI company focused on smart vending solutions, further demonstrating the team’s commitment to real-world tech applications.
This diverse and accomplished founding team gives IOST strong credibility in both engineering and business development.
How Does IOST Work?
At the heart of IOST’s architecture lies its proprietary consensus algorithm: Proof-of-Believability (PoB). Unlike traditional Proof-of-Work (PoW) or even Delegated Proof-of-Stake (DPoS), PoB combines elements of reputation, stake, and service performance to select block producers in a decentralized yet highly scalable way.
Understanding Proof-of-Believability (PoB)
PoB operates through a decentralized election process that selects a committee of nodes responsible for producing blocks. What sets it apart is its use of Servi, a dynamic reputation score that balances voting power with node performance and behavior.
Instead of relying solely on token holdings or votes, IOST evaluates nodes based on:
- Stake size
- Historical reliability
- Network contribution
- Service quality
This ensures that even smaller stakeholders can participate meaningfully in network governance, promoting decentralization without sacrificing speed.

The Node Election Process
To maintain network integrity, IOST implements a multi-layered node application system. In the current version, candidates must receive votes equivalent to at least 0.02% of the total network stake to qualify as validators.
Once eligible, nodes enter the committee selection process, which runs in cycles every 10 minutes. Each cycle consists of three stages:
- Service Allocation: All candidates earn Servi points proportional to their received votes.
- Committee Formation: The top 17 nodes with the highest Servi scores are selected to produce blocks in the next round.
- Servi Reset: After block production, the Servi balance of all elected nodes is reduced by the amount held by the 17th-ranked node—effectively resetting the leader’s advantage and enabling rotation.
This dynamic balancing prevents long-term dominance by any single node group and encourages continuous participation.
Node Rewards and Voter Incentives
IOST distributes rewards across three main categories:
- 25% to nodes for block production
- 50% to voters who stake their tokens
- 25% to contributors who enhance the IOST ecosystem
Nodes earn income from transaction fees (10–30%), while voters share 50% of node rewards (excluding block production bonuses). Additionally, stakers receive 100,000 GAS per day per IOST staked, which can be used to cover transaction costs—making participation cost-efficient.
Developers and dApp teams also benefit by earning a percentage of network fees generated within their applications, creating strong incentives for ecosystem growth.
Example of Servi Dynamics
Imagine five candidate nodes—A, B, C, D, and E—with initial Servi scores of 10, 8, 5, 4, and 1 respectively.
- Round 1: A, B, and C form the committee. Their Servi is reduced by 5 (C’s score), leaving them with 5, 3, and 0.
- Round 2: After earning new Servi, balances become 15, 11, 5, 8, and 2. Now A, B, and D are selected.
- Round 9: Even Node E—with only 1 Servi per round—can eventually enter the committee due to balanced resets.
This illustrates how PoB enables fair rotation and sustained participation.
Key Technological Features of IOST
1. High Transaction Speed
IOST boasts a theoretical throughput of 100,000 transactions per second (TPS)—far exceeding Ethereum’s current capacity. This makes it ideal for mass-market applications like gaming, social media, and decentralized exchanges.
2. Efficient Distributed Sharding (EDS)
IOST uses Efficient Distributed Sharding (EDS) to split the blockchain into smaller sub-chains (shards), each capable of processing transactions independently. The main chain remains unchanged, ensuring security while boosting scalability.
A mechanism called TransEpoch securely reassigns validators between shards during epoch transitions, preventing centralization risks.
3. Micro State Blocks (MSB)
To reduce storage overhead and improve efficiency, IOST employs Micro State Blocks (MSB). Instead of storing full state changes with every block, MSBs record only incremental updates—dramatically lowering data requirements and verification costs.
This allows more participants to run nodes without high-end hardware, enhancing decentralization.
4. Atomix Protocol
For cross-shard transactions, IOST uses Atomix, a fast atomic commit protocol that ensures consistency and validity across shards under PoB consensus. This guarantees secure and reliable inter-shard communication—an essential feature for complex dApps.

What Is IOST Coin Used For?
IOST is the native utility token of the IOST blockchain. It serves multiple functions:
- Paying transaction fees and smart contract execution costs
- Staking to vote for nodes and earn rewards
- Accessing shared network resources like storage (iRAM) and bandwidth (iGas)
- Rewarding developers and ecosystem contributors
- Facilitating peer-to-peer payments within dApps
With over 60 million processed transactions and 600,000 registered users, IOST has already demonstrated real-world adoption across gaming, gambling, and decentralized finance (DeFi) applications.
Is IOST a Good Investment?
While past performance doesn’t guarantee future results, several factors suggest IOST could be worth considering:
- Strong technical foundation with innovative solutions like PoB and EDS
- Experienced team with proven track records
- Growing ecosystem with active dApps
- Low current price point offering potential upside
However, like all cryptocurrencies, IOST is highly volatile. Investors should conduct thorough research and consider risk tolerance before investing.
