The world of decentralized applications (dApps) is growing rapidly, and with it, the demand for scalable, secure, and high-performance blockchain platforms. Among the contenders aiming to lead this next wave of innovation is IOST—a blockchain designed to support mass adoption through cutting-edge technology and efficient consensus mechanisms. This guide dives deep into what IOST is, how it works, its unique features, and where you can buy it securely.
Whether you're a developer exploring new platforms or an investor scouting promising altcoins, understanding IOST’s role in the evolving dApp ecosystem is essential. Let’s explore why IOST positions itself as a serious competitor to giants like Ethereum, EOS, and TRON.
What Is IOST?
IOST is a standalone, high-performance blockchain network built specifically for hosting scalable decentralized applications. Unlike traditional blockchains that struggle with congestion under heavy usage, IOST was engineered from the ground up to handle millions of users and transactions efficiently.
At its core, IOST leverages a suite of proprietary technologies designed to enhance speed, security, and decentralization:
- Proof of Believability (PoB): A consensus algorithm that selects reliable nodes based on reputation and stake, reducing energy consumption while maintaining trust.
- Efficient Distributed Sharding (EDS): Enables parallel transaction processing across multiple shards, significantly increasing throughput.
- Micro State Blocks: Optimizes storage by recording only changes in account states rather than full data sets.
- Atomix: A distributed atomic transaction protocol ensuring data consistency across shards.
- TransEpoch: Facilitates smooth transitions between network epochs without downtime.
Together, these innovations allow IOST to claim a theoretical throughput of up to 100,000 transactions per second (TPS)—far surpassing Ethereum’s ~20 TPS, TRON’s ~2,000 TPS, and EOS’s ~4,000 TPS.

Key Features That Set IOST Apart
High Scalability Through Sharding
IOST’s Efficient Distributed Sharding splits the network into smaller partitions (shards), each capable of processing transactions independently. This parallelization drastically reduces latency and increases scalability without compromising security.
Energy-Efficient Consensus
By replacing energy-intensive Proof of Work (PoW) with Proof of Believability, IOST minimizes environmental impact. PoB evaluates nodes based on their historical behavior, token holdings, and community reputation—only the most trustworthy nodes are chosen to validate blocks.
Low Fees and Fast Finality
Due to its optimized architecture, IOST offers near-instant finality with negligible transaction fees, making it ideal for microtransactions and real-time applications such as gaming, social media, and IoT services.
Developer-Friendly Ecosystem
IOST supports smart contracts written in JavaScript and Python, lowering the barrier to entry for developers unfamiliar with more complex languages like Solidity. The platform also provides SDKs, APIs, and comprehensive documentation to accelerate dApp deployment.
Who Created IOST?
IOST was founded in 2017 by a team of tech-savvy entrepreneurs and engineers:
- Jimmy Zhong
- Terrence Wang
- Justin Li
- Ray Xiao
- Sa Wang
- Kevin Tan
Many of the founders are alumni of top-tier institutions like Harvard, MIT, and Stanford, bringing strong academic and industry backgrounds to the project. Their vision was clear: build a blockchain capable of supporting mainstream dApps at scale.
To foster innovation within the ecosystem, the team launched Bluehill, a $50 million incubator and accelerator program modeled after Ethereum’s ConsenSys. Bluehill funds and mentors projects that contribute to IOST’s growth, helping bootstrap a vibrant developer community.
How Does IOST Work?
IOST operates on a delegated proof-of-stake model enhanced by its unique PoB mechanism. Here's how it functions:
- Node Selection: Community members vote for trusted entities to become Service Nodes or Partner Nodes.
- Staking & Voting Rewards: Both voters and elected nodes earn IOST tokens as rewards.
- Minimum Threshold: To run a node, candidates must secure at least 2.1 million votes.
- Token Emission: The total supply is capped at 21 billion IOST tokens. Each year, 2% new tokens are minted to reward nodes and voters. An additional 1% supports ecosystem development initiatives.
This incentive structure promotes active participation while maintaining network integrity.
What Can You Do With IOST?
The IOST token serves multiple utility functions within the ecosystem:
- Pay for dApp Services: Users can pay developers or service providers directly using IOST.
- Cover Transaction Fees: All on-chain operations require small gas fees paid in IOST.
- Participate in Governance: Token holders influence network upgrades and policies through voting.
- Build Credibility Scores: The PoB system uses token holdings and behavior to calculate node reliability.
Developers can leverage IOST to create fast, low-cost dApps in sectors like finance, entertainment, supply chain, and identity verification.

Where and How to Buy IOST
Purchasing IOST is straightforward if you follow these steps:
Choose a Wallet: Since IOST migrated from an ERC-20 token to its own blockchain, ensure your wallet supports native IOST. Recommended options include:
- TokenPocket
- PureWallet
- Guarda Wallet
- Set Up Your Wallet: Create a secure wallet and back up your recovery phrase.
Select an Exchange: Buy IOST on reputable platforms such as:
- Binance
- KuCoin
- OKX
- Gate.io
- Deposit Funds: Use fiat (via credit card or bank transfer) or crypto (like USDT or BTC) to fund your exchange account.
- Buy IOST: Place an order for IOST/USDT or IOST/BTC pair depending on available markets.
- Withdraw to Wallet: For maximum security, transfer your tokens to your personal wallet instead of leaving them on exchanges.
Frequently Asked Questions (FAQ)
Is IOST a Good Investment?
While IOST offers strong technical foundations and scalability advantages, its market adoption remains limited compared to leaders like Ethereum or Solana. As with any cryptocurrency, thorough research and risk assessment are crucial before investing.
Can I Stake IOST Tokens?
Yes. By participating in voting for Service Nodes or running a node (with sufficient votes), you can earn staking rewards in newly issued IOST tokens.
How Secure Is the IOST Network?
IOST combines cryptographic security with behavioral scoring via PoB. Its sharded architecture has undergone third-party audits, though long-term resilience depends on continued development and user adoption.
Does IOST Support Smart Contracts?
Absolutely. Developers can deploy smart contracts on IOST using familiar programming languages like JavaScript and Python.
Is IOST Eco-Friendly?
Compared to PoW blockchains like Bitcoin, IOST is significantly more energy-efficient due to its PoB consensus model.
What Makes IOST Different From Ethereum?
IOST focuses on higher throughput and lower fees through sharding and innovative consensus design. While Ethereum emphasizes decentralization and security, IOST prioritizes scalability for mass-market applications.
Final Thoughts
IOST represents an ambitious attempt to solve one of blockchain’s biggest challenges: scalability without sacrificing decentralization or security. With advanced features like sharding, PoB consensus, and developer-friendly tooling, it has the technical foundation to support widespread dApp usage.
