IOST, which stands for Internet of Services Token, is often described as a next-generation blockchain. It's a cryptocurrency project built by developers who aimed to take the existing Ethereum technology as a foundation and significantly improve upon it. While relatively unknown compared to major cryptocurrencies, IOST has the potential to be a standout performer in the coming months and years due to its unique technological approach.
This guide explores what makes the IOST coin special, how its technology works, and why it matters in the competitive blockchain landscape.
Key Features of IOST
Launched in 2019, IOST entered the market with claims of a revolutionary and superior technology. Its promotional slogans highlighted a 5x higher throughput than the top 37 leading cryptocurrencies at the time. The project was founded by a team including CEO Jimmy Zhong, along with Kevin Tan, Sa Wang, Justin Li, Ray Xiao, and Terrence Wang.
From the outset, IOST was designed as a decentralized, ultra-fast blockchain network. Its core innovation is the Proof of Believability (PoB) consensus algorithm, a next-generation mechanism designed to overcome the limitations of older systems.

How Does IOST Work?
The primary goals of IOST are to serve as the foundational architecture for leading online services and to address the scalability and security requirements of a decentralized economy. It positions itself as a clear alternative to the Ethereum network, offering developers lower transaction fees and extremely fast processing times.
As an open-source project, IOST utilizes the JavaScript programming language. It currently claims the capability to process up to 100,000 transactions per second (TPS) in parallel. This is achieved through its novel PoB consensus mechanism and a dynamic sharding system called Efficient Distributed Sharding (EDS).
Built with enterprise integration in mind, IOST offers commercial solutions to help traditional businesses adopt or transition to blockchain technology. The native IOST token is the fuel for this service-oriented blockchain, used for transactions, network fees, and governance.
The network is decentralized, with over 400 nodes currently participating in the ecosystem. Its developer-friendly nature, thanks to the use of JavaScript, lowers the barrier to entry for creating decentralized alternatives to popular applications like Facebook or Amazon.
Core Problems IOST Aims to Solve
IOST directly addresses the classic blockchain trilemma: achieving scalability, low-cost payments, and high-speed transaction processing without compromising security. It aims to solve the fundamental problem that even the most popular cryptocurrencies face: the slow, sequential processing of transactions.
By enabling significantly shorter transaction times even under heavy load, IOST leads to lower overall transaction costs. It also supports the provision and development of compact, efficient decentralized applications (dApps).
In terms of scalability, IOST's 8,000 TPS and a block time of 0.5 seconds allow it to power nearly any online application without speed penalties. Beyond the technical infrastructure, the IOST team is also developing ancillary services like feedback systems and decentralized storage solutions.
The Technical Solution: PoB and EDS
To realize its vision of ultra-fast processing, IOST developed an entirely new consensus mechanism: Proof-of-Believability (PoB). While cryptocurrencies like Bitcoin (Proof-of-Work) and Ethereum (Proof-of-Stake) rely on established procedures, IOST's PoB is a unique, credibility-based system.
This mechanism validates a node based on several factors:
- The amount of IOST tokens staked.
- The number of non-tradable Servi tokens held (which function as a reputation score).
- The node's previous transaction history.
- The number of positive ratings it has received.
This approach reduces the massive computational workload required by Proof-of-Work while maintaining network security.
PoB is used in combination with the dynamic Efficient Distributed Sharding (EDS) protocol. Sharding technology divides a blockchain network into smaller groups of nodes (shards) that can process transactions simultaneously for greater efficiency. EDS focuses on improving reliability even in the presence of potentially malicious nodes.
A key component of EDS is the Distributed Random Protocol (DRP), which ensures nodes never know which shard they currently belong to. This protocol incorporates verifiable secret sharing and zero-knowledge proofs, resulting in higher tamper resistance for the blockchain.
Potential and Opportunities for IOST
The potential for IOST is vast. In today's world, nearly every industry requires the processing and transmission of large data volumes quickly and at low hardware and energy costs. IOST has already set a notable benchmark by reportedly exceeding Ethereum's daily transaction volume for dApps.
The platform also supports the creation and trading of Non-Fungible Tokens (NFTs) on its dedicated NFT platform, which is characterized by high scalability and rapid response times. A significant mark in its favor is that the IOST network has experienced zero downtime since its launch in 2019.

FAQ: Frequently Asked Questions
What is the main advantage of IOST over Ethereum?
IOST's primary advantage is its significantly higher transaction throughput and lower fees, achieved through its Proof-of-Believability consensus and Efficient Distributed Sharding. This makes it more scalable for applications requiring high-speed data processing.
How can I acquire IOST tokens?
IOST tokens can be purchased on several major cryptocurrency exchanges. They are traded against other cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH), and sometimes against fiat currencies, depending on the exchange.
What is Proof-of-Believability (PoB)?
Proof-of-Believability is a custom consensus algorithm developed by IOST. It determines which node creates the next block based on a combination of factors including staked tokens, reputation (Servi tokens), and past behavior, allowing for faster and more efficient consensus than Proof-of-Work or Proof-of-Stake.
Is IOST a good platform for developers?
Yes, IOST is considered very developer-friendly. It uses JavaScript, a widely known and easy-to-learn language, and its open-source communication protocol allows a large community of developers to build and adapt dApps for their specific needs.
What are the risks of investing in IOST?
As with any cryptocurrency, investment carries risk. The main challenges for IOST include competing with established giants like Ethereum and achieving widespread adoption for its technology despite being a newer project in a crowded market.
Tokenomics and Distribution
The initial supply of IOST tokens was created in 2018 through an Initial Coin Offering (ICO). The total maximum supply is capped at 90 billion IOST. The initial allocation was distributed as follows:
- 40% was sold directly to the public.
- 35% was allocated to the IOST Foundation for ecosystem development.
- 12.5% was reserved for community initiatives.
- 10% was allocated to the core IOST team.
- 2.5% was given to advisors and early investors.
Developers who help maintain the blockchain are also rewarded with IOST tokens. The circulating supply is consistently updated on major cryptocurrency data aggregators.
Technical Specifications
The IOST token originated as an ERC-20 token on the Ethereum blockchain but now operates on its own mainnet. Its ecosystem features custom-defined nodes and its own programmed consensus algorithm.
| Technical Aspect | IOST Implementation |
|---|---|
| Consensus Protocol | Proof-of-Believability (PoB) |
| Consensus Algorithm | PoB |
| Block Time | 0.5 seconds |
| Throughput | Up to 8,000 - 100,000 TPS (claimed) |
| Programming Language | JavaScript |
| Developer Resources | Comprehensive guidelines available |
The network also employs a Byzantine Fault Tolerance (BFT) algorithm, ensuring that at least two-thirds of the nodes must agree to meet consensus conditions before a new block is added to the blockchain.
