IOST (IOST): What It Is, Uses and Risks

IOST is a blockchain project that launched in 2018. Its public description says it is building high-throughput infrastructure for online services and decentralized applications. The project names a consensus method called Proof-of-Believability, which weighs factors such as token balance, reputation-based balance, network contributions and user behavior when deciding how validators should behave. It also cites a Byzantine Fault Tolerance variant, microstate blocks, an Atomic Commit protocol and a dynamic sharding protocol as ways to speed up transactions and reduce storage and processing costs for validators. The project states it raised $40 million from investors including Sequoia and Matrix. Search summaries describe IOST as a wider ecosystem with its own nodes, wallets and consensus protocol, and point to a newer push called IOST 3.0, focused on a payment infrastructure named PayPIN. These are the project's own claims, so readers should check them against independent technical documentation before relying on them.

According to search summaries, the IOST token is used to pay for services, goods and smart contract fees on the platform. It is also described as a medium of exchange that helps process transactions and supports validation on the network. The project's description says anyone can take part at every layer, from using services on its blockchain to running a node and validating transactions. Public sources provided do not name specific dApps built on IOST, fee levels, or staking returns, so this page does not cover them. For current uses, the project's official documentation is the best place to check, since its features and roadmap have changed over time.

As of 2026-11-05, the data shows a price of about $0.00069 and a market capitalization of about $25.3 million, which ranks around 725th among tracked tokens. Circulating and total supply are both about 36.69 billion, against a stated maximum supply of 90 billion, so roughly 41% of the maximum is in circulation. The 24-hour trading volume was about $3.7 million. Over the previous seven days the price fell about 11%, and over the past year it fell about 63%. The all-time high was about $0.13 on 2018-01-23, and the all-time low was about $0.00053 on 2026-08-19. These figures change constantly and are not a forecast of future prices.

The data lists IOST as issued on BNB Chain and does not list a native chain for the token. The IOST project runs its own blockchain, so the token on BNB Chain should be treated as a separate deployment that may not match the project's own network in every respect. Sending tokens on the wrong network, or relying on a bridge or wrapped version, adds risk. Price risk is significant, as the large one-year decline shows. A small market capitalization and modest trading volume can also make prices move sharply on relatively little buying or selling. Project claims about speed, security and team quality are not independently verified. Roadmap changes, such as the IOST 3.0 plans, may not deliver as described. Scam tokens and impersonation of the project are also common in this market.

Store BNB Chain tokens in a wallet that supports that network, and confirm the network before every transfer. Keep your recovery phrase offline and never share it with anyone, including people who contact you claiming to offer support or a reward. Be cautious of links and messages that push you to connect a wallet or approve a request you did not start. Testing with a small amount before a larger transfer can prevent costly mistakes. Keep records of what you bought and sent, since these may matter for tax reporting in your country.
