What is IOST (IOST)?

Quick Facts

  • Full name: Internet of Services Token
  • Launched: 2018, mainnet live in 2019
  • Consensus: Proof of Believability (PoB)
  • Max throughput: Up to 100,000 transactions per second
  • Token uses: Gas fees, staking, voting, governance
  • Backers: Sequoia Capital and Zhenfund
  • Founded by: Jimmy Zhong, Terrence Wang, and Princeton engineers

Introduction

IOST stands for Internet of Services Token. It is a public blockchain platform built to support high-performance decentralized applications and online services. Its core design goal is to solve the scalability trilemma — balancing decentralization, security, and speed — without the trade-offs seen in earlier blockchains.

The native IOST token powers the entire ecosystem, covering transaction fees, staking, and governance.

History & Background

IOST was founded in 2017 and raised $35 million in a private token sale. The team, composed of engineers from Princeton and backed by prominent venture capital firms, set out to build a blockchain capable of industrial-scale throughput.

In 2019, the mainnet — called Olympus v1.0 — went live. This marked the transition from an ERC-20 token to a fully independent blockchain. Holders swapped their ERC-20 IOST tokens for native IOST tokens on a 1:1 basis.

How IOST Works

At the heart of IOST is the Proof of Believability (PoB) consensus mechanism. PoB divides validators into two groups — 'Believable' and 'Normal' leagues — and rotates a committee of 17 nodes every 10 minutes to produce blocks. This rotation boosts throughput while keeping the network decentralized.

IOST also uses Efficient Distributed Sharding (EDS), which splits the network into smaller parallel shards to process transactions simultaneously. Together, PoB and EDS allow IOST to handle up to 100,000 TPS, far exceeding Bitcoin and Ethereum.

Developers can build smart contracts on IOST using JavaScript and Go, lowering the barrier to entry for a large existing developer base.

Tokenomics

The total IOST supply is distributed across several pools. At the time of the private sale, allocations were structured as: 40% to the private sale, 10% to the team, 35% to the token treasury, 5% to strategic sales, 5% to the community, and 2.5% each to advisors and business development.

The Servi sub-token is a built-in mechanism that rewards good actors on the network, adding an extra incentive layer beyond standard block rewards.

Ecosystem & Use Cases

IOST supports a diverse range of decentralized applications, including DeFi protocols, gaming apps, and NFT platforms. It supports the IRC-721 NFT standard and is noted for near-feeless transactions, making it attractive for NFT marketplaces and high-frequency use cases.

The platform also offers Blockchain-as-a-Service (BaaS) tools, including authorization management, multi-cloud support, and cross-chain compatibility.

Team, Governance & Community

IOST is governed through a node voting system where token holders stake IOST to vote for network validators. Node operators who receive enough votes participate in block production and earn rewards.

The project maintains an active community across Telegram, Twitter, Reddit, and Medium, with ongoing developer programs and ecosystem grants to attract builders.

Advantages

  • High throughput: Up to 100,000 TPS enables real-world, industrial-scale usage.
  • Developer-friendly: Smart contracts support JavaScript and Go, lowering entry barriers.
  • Low fees: Near-feeless transactions make micro-payment use cases practical.
  • Strong backing: Venture capital support from Sequoia Capital and Zhenfund.
  • Flexible ecosystem: Covers DeFi, NFTs, gaming, and BaaS services.

Risks & Challenges

  • Competition: IOST competes with well-resourced layer-1 platforms like Ethereum, BNB Chain, and Solana.
  • Adoption: Attracting mainstream developers and enterprises remains an ongoing challenge.
  • Token supply: A large circulating supply can create downward price pressure.
  • Ecosystem maturity: The DApp ecosystem is smaller than those of more established platforms.

Long-Term Vision

IOST aims to serve as the foundational blockchain infrastructure for large-scale online services and Web3 applications. With its high TPS, developer-friendly environment, and expanding ecosystem, the project positions itself as an enterprise-grade public chain capable of bridging traditional internet services with decentralized technology.

Frequently Asked Questions

IOST stands for Internet of Services Token. It is both the name of the blockchain platform and its native cryptocurrency.

Proof of Believability is IOST's unique consensus mechanism that divides validators into two groups and rotates a committee of 17 nodes every 10 minutes to produce blocks. This design improves throughput while preserving decentralization.

IOST can process up to 100,000 transactions per second. This is achieved through a combination of PoB consensus and Efficient Distributed Sharding (EDS).

The IOST token is used to pay gas fees, stake for network participation, vote for validator nodes, and take part in platform governance.

IOST launched its mainnet, called Olympus v1.0, in 2019. At that point, ERC-20 IOST tokens were swapped 1:1 for native IOST tokens on the new blockchain.

IOST supports JavaScript and Go for smart contract development. This broad language support makes the platform accessible to a wide range of existing developers.

Servi is a built-in sub-token on the IOST network awarded to participants who act in good faith. It serves as an additional incentive mechanism on top of standard block rewards.

IOST was founded by Jimmy Zhong, Terrence Wang, and a team of engineers from Princeton University. The project received backing from Sequoia Capital and Zhenfund.
