OKChain blockchain infrastructure testest goes live with DEX



OKEx, a leading cryptocurrency exchange company announced today that OKChain, its native decentralized public chain that supports various decentralized applications and allows users to issue their own cryptocurrencies, create trading pairs, and trade freely, has gone live on testnet.

OKChain maintains a “one application, one chain” operation principle that allows it to power applications for everyone.

“In the era of blockchain, we must embrace openness and complete decentralization. We want to build a decentralized and open public chain to empower every participating node with the same power to run and issue decentralized apps freely, that’s why we started to build OKChain. Our goal is to be as decentralized as Bitcoin, to build a highly efficient public chain that can be used by anyone around the world, to create a truly borderless ecosystem.”
– The OKEx Team

Special Features Include:

Multi-chain Development

  • Significantly speed up the development process: By developing multi-chains, various applications can be developed on OKChain at the same time while achieving mutual connections;
  • Sharding according to business data: OKChain implements sharding according to business data, effectively solves the scaling problem of traditional sharding, and can support large-scale applications;
  • Positive internal competitions: Parallel development allows different parties to develop an application at the same time, fostering a positive competitive environment for products to implement regular upgrades, so that users can get the best user experience.

Data Layering

OKChain separates data into 3 layers: block, operations, and off-chain data. It meets the needs of reducing costs by combining the current systems, which can improve the system consensus speed and expand data dimensions on-chain.

  • Block data: As the fundamental data layer, block data retains the advantages of blockchain technology – they are irreversible and unable to tamper with;
  • Operations data: Through on-chain calculation algorithms, only operating data are kept when transmitting data. It can effectively lower the amount of data transmitted when a large amount of data needs to reach a consensus, thus greatly improve the block operation speed;
  • Off-chain data: OKChain allows easy incorporation with PLUS, i.e. traditional data software such as MySQL and Redis, or syncing with IPFS and other databases, to effectively expand data communication channels from traditional data to blockchain data.

Ecological Development

The OKChain development team aims to build an open and autonomous ecosystem on OKChain to achieve the large-scale commercial application of blockchain technology.

  • OKChain allows users to issue their own cryptocurrency on the public chain. OKEx will also migrate OKB and USDK to OKChain;
  • Users can build their own decentralized exchange and customize what assets and trading pairs they want to list.


With OKChain, OKEx has launched OKEx DEx, a decentralized application based on OKChain. To ensure a better trading experience and liquidity, OKEx DEx supports real-time settlement in a trustless manner.

Compared to centralized exchanges, OKEx DEx is a more open, inclusive, and secure decentralized exchange: Users have complete control over their assets; Profits are settled daily to users’ accounts, and trading records are transparent on-chain.

“The OKChain team hopes that more users can capitalize on this tool to build their own DEx on OKChain.”

Blueprint of OKChain

  • Distribution of DeFi applications. Users can build their own financial applications based on blockchain technology and crypto on OKChain, creating a highly autonomous financial system;
  • Support smart contracts;
  • Support BTC cross-chain, acting as a bridge to connect BTC to the world. OKEx market data and blockchain explorer will also be available on OKChain in the future.

The above features are the major focus and development of OKChain  OKEx hopes to build an open and free platform for its global users, which can adapt to different application scenarios and eventually creating a unique OKChain ecosystem.

OKB Future Development

OKB is the native token of the OKEx ecosystem, with wide support from millions of users since its birth. OKEx says it will continue to explore and expand the ecological applications of OKB and improve its buy-back and burn scheme.

Following the launch of the OKChain testnet, OKEx will burn a total of 700 million unissued OKB. OKB will enter absolute deflation and become a fully circulated platform token. OKEx will not retain any OKB. The burned tokens come entirely from the market via the buy-back and burn scheme. OKEx has already burnt 13,978,364 OKB from the initial circulation of 300 million OKB. The current circulating amount is now 286,021,636 OKB (OKB blackhole address: 0xff1ee8604f9ec9c3bb292633bb939321ae861b30).

Despite having the ability to issue additional tokens in the current OKB ERC-20 smart contract code, OKEx will not be issuing any and it plans to delete the smart contract code once OKB is migrated to the OKChain mainnet.

New Native Token: Giving Back to OKB Holders

OKChain is a native public chain that adopts the DPoS consensus mechanism. In order to fulfill the DPoS consensus requirement, OKEx has issued OKT as the native token of OKChain. The issuance of OKT will be on the genesis block and node block, and is expected to increase by 1-5% every year, details will be announced when the mainnet goes live.

OKB holders are an important driving force for the development and promotion of OKChain; OKEx will map 100% of the genesis block to OKB holders. In the future, OKT and OKB will be interconnected to foster the ecological development of OKChain.

OKT and OKB are inseparable on OKChain, as OKT will empower the development of the OKB ecosystem. OKT trading will be available when the OKChain mainnet is live.

Using The Testnet

In order to optimize the performance of the OKChain testnet as the fundamental infrastructure in the decentralized field; all users are invited to experience the power of OKChain. Participating users can also receive free OKT testnet coins.
