OKB (OKB) Cryptocurrency: Comprehensive Overview
Core Definition and Technology
OKB is the official utility and gas token of the OKX ecosystem. Founded in 2017, OKX introduced OKB to the market a year later, in March 2018. As of August 2025, it is mainly issued on the X Layer blockchain (Ethereum L2), granting users trading fee discounts, DeFi access, and platform perks.
Blockchain Architecture
X Layer is an Ethereum Layer 2 network built on Polygon CDK and secured by Ethereum's robust validators. It features zkEVM technology, blending EVM compatibility with fast, low-cost transactions. X Layer processes thousands of transactions per second, with block times under 2 seconds.
OKB is issued on X Layer (Ethereum Layer 2), Ethereum (ERC-20), and OKTChain. The token natively supports multiple chains, including OKXChain and the EVM-compatible X Layer, opening up more use cases for builders and users alike.
Primary Use Cases and Real-World Applications
Exchange Platform Utilities
The coin is used to calculate and pay trading fees, grant users access to voting and governance on the platform, and reward users for holding OKB. Beyond its transactional utility, OKB offers holders exclusive benefits like reduced trading fees, access to token sales, and staking rewards.
OKB holders get early/preferential access to curated token sales and launches. Stake OKB to earn interest or participate in savings programs for passive income.
Ecosystem Integration
DeFi Integration: OKB is listed on leading DeFi platforms for lending, borrowing, and liquidity mining. Payment Acceptance: Dozens of global service providers now accept OKB for payments in travel, retail, and online services. NFT & Gaming: Use OKB in NFT marketplaces and blockchain games that partner with OKX.
Governance and Community Participation
OKB holders can participate in protocol improvement proposals and ecosystem decisions. OKB token holders can vote on new product launches, platform upgrades, and major proposals, directly influencing OKX's roadmap.
Founding Team and Project History
Leadership
Jay Hao joined OKEx as CEO from the beginning, and he still holds the position. Hao has dedicated his career to technology and engineering. He has followed the blockchain industry for quite some time, with a focus on blockchain-based apps for video streaming and mobile gaming. Prior to joining OKEx, Hao had twenty years of experience in the semiconductor industry.
Another key management team member is Mingxing "Star" Xu. He founded OKCoin in China in 2013 and has earned himself a big reputation in the industry. In 2017, Xu co-founded the separate OKEx exchange in Malta, which operates under a separate legal entity. Today Xu is the CEO of the OK Group.
Project Timeline
Founded in 2017, OKX introduced OKB to the market a year later, in March 2018. In September 2020, the exchange burned 700 million unissued OKB tokens, bringing the total supply down to 300 million. The mainnet of OKChain (now known as OKC), the exchange's proprietary blockchain, was launched between December 2020 and January 2021. In January 2022, OKEx rebranded to OKX to reflect its expansion beyond a simple exchange.
Tokenomics
Supply Structure
With a fixed supply of 21 million tokens, OKB's scarcity and integration into OKX's ecosystem make it a valuable asset for traders and investors seeking to engage with a rapidly growing blockchain network. Fixed Max Supply: 300 million OKB tokens. Current Circulation: As of June 2024, all tokens are in circulation, with no future issuances.
OKB is fully unlocked. As of today, approximately 21,000,000 OKB which is 100.00% of OKB's total supply has been unlocked.
Distribution Model
The initial token distribution allocated 40% to founding team members, 10% to early investors, and 50% to community rewards and ecosystem development. Following the 2022 lock-in period expiration, tokens underwent strategic redistribution to optimize long-term holder benefits and platform alignment.
Deflationary Mechanism
Each quarter, OKX uses platform revenue to buy back OKB from the market and burns those tokens, making them permanently unrecoverable. Since 2019, over 70 million OKB have been burned. This regular reduction in supply helps drive value for long-term holders and increases scarcity.
The systematic buyback program allocates 30% of OKX's market transaction revenue to quarterly token repurchases. These acquired tokens are permanently removed from circulation through verifiable burn mechanisms. This commitment to value creation has demonstrated consistent results through multiple market cycles, establishing OKB as one of the few utility tokens with proven deflationary characteristics.
Consensus Mechanism and Network Security
X Layer Architecture
~$0.0005 USD · Average cost per transaction · 400 ms · Block time · 5,000 · Average TPS (transactions per second)
A layered architecture reduces consensus times, improves scalability, and boosts security.
Security Infrastructure
OKX deploys a series of hot and cold wallets for its exchange's operations and security. Servers with a hot wallet, which holds 5% of the exchange funds, manage daily deposits and withdrawals. The rest are stored offline in cold wallets that require at least two authorized personnel to access.
OKX has not suffered from any hacks or exploits to date.
OKX stands out by publishing regular proof-of-reserves audits, showing verifiable user asset backing. BNB (Binance) and KuCoin have made some proof-of-reserves moves, but OKX updates monthly and includes third-party attestations.
Key Partnerships and Ecosystem Integrations
Infrastructure Partners
Chainlink is the industry-standard oracle platform. BlockPI provides reliable globally distributed blockchain infrastructure, offering fast, stable, high-performance RPC services, dedicated node services, node and validator services, and account abstraction infrastructure services for Web3 builders.
DeFi and Financial Services
Businesses like Bitpie, Blocto, and Cobo offer blockchain financial services like cryptocurrency storage and trade. They provide external storage and handling of OKB tokens outside the OKX ecosystem.
Security Services
Blockchain security firms like Slow Mist, Beosin, CertiK, and Safeguard have partnered with OKX. They provide services like security and smart contract audits, security consultancy, risk monitoring, and alerts. DApps may access their services using OKB.
Competitive Advantages and Unique Value Proposition
Differentiation from Competitors
While other exchange tokens like Binance Coin (BNB) or Huobi Token (HT) have similar visions, OKB distinguishes itself with deep integration into both the OKX trading platform and its vibrant DeFi/L2 environment. OKB chain leverages a hybrid model (EVM compatibility, Cosmos SDK), providing flexibility for users and developers. The tokenomics also favor long-term holders, with a proven burn mechanism and transparent supply.
Fee Discount Structure
OKB: Up to 40% trading fee discount on OKX; accessible staking options; eligible for token sales like Jumpstart. BNB: Up to 25% trading fee discount on Binance; staking on BNB Chain; BNB Vault and launchpad access.
Transparency and Trust
OKX publishes detailed proof-of-burn and transparency reports each quarter, fostering trust and openness with the community. OKB is unique in completing its team unlock schedule, ensuring full liquidity.
Current Development Activity and Roadmap
Recent Developments
In August 2025, OKB underwent its biggest technical shift yet—migrating its primary issuance to X Layer. Demand for better DeFi integrations and EVM compatibility led OKX to introduce X Layer in August 2025. Built using Polygon's Chain Development Kit (CDK) and secured by Ethereum, X Layer provides near-instant transactions and minimal fees—addressing core challenges of previous chains.
Ecosystem Expansion
The ongoing evolution of OKB's utility reflects OKX's commitment to continuous innovation. Recent developments include enhanced staking options, expanded governance capabilities, and integration with emerging DeFi protocols. These advancements position OKB for sustained relevance in the rapidly transforming digital asset landscape.
