In the fast-moving world of blockchain technology, finding a platform that balances scalability, security, and decentralization remains a top priority. While many projects aim to solve these challenges, few deliver on all fronts. Enter IOST—a high-performance blockchain network engineered to meet the demands of modern decentralized applications.
Conceived in 2017 by visionaries including Jimmy Zhong, Terrence Wang, and Ray Xiao, IOST was built with a clear mission: to overcome the scalability bottlenecks that limited earlier blockchains like Ethereum. The project gained early traction with a successful Initial Coin Offering (ICO) in January 2018, raising $31.3 million and setting the stage for rapid development.
By February 2019, IOST launched its mainnet, migrating from Ethereum and introducing its groundbreaking Proof-of-Believability (PoB) consensus mechanism. This innovation helped IOST emerge as a top-tier public blockchain, standing alongside industry leaders such as EOS, Tron, and Ethereum.
As the ecosystem matured, IOST expanded into key areas like DeFi, NFTs, and cross-chain interoperability, consistently pushing the boundaries of what a scalable blockchain can achieve.
How Does IOST Work? The Core Technologies Behind the Network
IOST’s performance edge comes from two foundational technologies: Proof-of-Believability (PoB) and Efficient Distributed Sharding (EDS). Together, they enable high throughput, low latency, and strong security—without sacrificing decentralization.
Proof-of-Believability (PoB): A Smarter Consensus Model
Unlike traditional Proof-of-Stake (PoS) systems that favor wealthier stakeholders, PoB introduces a reputation-based selection process for block producers. This ensures fair participation across a broader set of nodes.
The system relies on Servi, a dynamic point metric that evaluates node behavior based on factors like uptime, transaction validation accuracy, and community trust. Nodes must surpass a 0.02% voting threshold to become eligible candidates.
Every 10 minutes, 17 nodes with the highest Servi scores are selected to form the block-producing committee. After each round, their Servi points are adjusted—specifically reduced by the amount held by the 17th-ranked node. This reset mechanism prevents dominance by any single group and promotes rotation, enhancing decentralization.

For example, in a simulated environment with five nodes (A–E) having Servi scores of 10, 8, 5, 4, and 1 respectively, only A–C initially produce blocks. Over time, as their points decrease due to participation, lower-ranked nodes like D and eventually E gain entry—demonstrating a truly dynamic and inclusive system.
Efficient Distributed Sharding (EDS): Scalability Without Compromise
To handle massive transaction volumes—up to 100,000 TPS—IOST uses EDS, an advanced sharding technique that divides the network into parallel-processing shards.
Each shard processes a subset of transactions simultaneously, drastically increasing throughput. But unlike conventional sharding methods that risk security fragmentation, EDS uses randomized node assignment to shards, making it extremely difficult for malicious actors to target or control any single shard.
This combination of speed and security makes IOST ideal for enterprise-grade applications and high-traffic DApps.
Key Features That Power the IOST Ecosystem
Beyond its core architecture, IOST integrates several innovative components designed to enhance functionality and user experience.
Micro State Block (MSB)
MSB reduces blockchain bloat by storing only incremental state changes instead of full transaction histories. This slashes storage requirements for validators, lowers bootstrapping costs, and encourages wider node participation—strengthening decentralization.
Atomix: Secure Cross-Shard Transactions
Atomix is an atomic commit protocol under development that ensures transaction integrity across different shards. Even in hostile (Byzantine) environments, Atomix verifies cross-shard operations, preventing double-spends and maintaining consistency across the network.
TransEpoch: Seamless Network Transitions
During epoch changes—when validator sets rotate—TransEpoch ensures uninterrupted transaction processing. This eliminates downtime and maintains reliability during critical network updates.
Cross-Chain Compatibility
IOST has partnered with Polkadot to build a cross-chain bridge, enabling seamless asset transfers between ecosystems. This strategic move enhances interoperability and expands access to multi-chain DeFi opportunities.
Real-World Use Cases of IOST
IOST isn't just technically advanced—it's built for real-world adoption across multiple domains.
Decentralized Applications (DApps)
With support for JavaScript and Solidity, developers can easily build DApps on IOST for gaming, social media, finance, and more. Its high-speed infrastructure ensures smooth user experiences even during peak usage.
Smart Contracts
Powered by PoB, IOST enables fast, secure execution of smart contracts—ideal for automating business logic without intermediaries.
Digital Identity & Data Storage
IOST’s robust security model makes it suitable for managing digital identities and sensitive data. Users retain control over their information while benefiting from tamper-proof verification.
Token Creation
Projects can launch custom tokens on IOST for fundraising (ICOs), loyalty programs, or utility purposes—all with minimal fees and high scalability.
Decentralized Finance (DeFi)
IOST supports DeFi innovations such as lending, staking, yield farming, and algorithmic stablecoins. In 2022, the team announced plans for a new decentralized stablecoin to improve price stability and oracle reliability.
NFTs on IOST
The blockchain supports the IRC-721 standard and hosts platforms like Revival and TokenLink. With near-instant transactions and negligible fees, IOST offers an optimal environment for NFT creators and traders.
What Is the IOST Coin?
IOST is the native cryptocurrency of the IOST blockchain. With a total supply of 18.7 billion tokens, it powers all on-chain activities—from transaction fees to resource allocation.
Funds raised during the private sale were managed in a cold multi-signature wallet, requiring approval from at least two of three executives (CEO, CTO, CDO). As of early 2018, nearly 10% of funds had already been allocated to community growth initiatives.
Token distribution includes:
- 40% – Private Sale
- 35% – Token Treasury
- 10% – Team (unlocked in 2019)
- 5% – Community & Marketing
- 5% – Strategic Sales
- 2.5% – Advisors & BD
IOST tokens are used to pay for smart contract execution, storage space, and network services. They also serve as rewards for contributors and can be exchanged for other tokens issued on the platform.
