OKX collaborates with Polygon Labs to launch zero-knowledge L2 "X1" testnet, with OKB as the native token.

The cryptocurrency exchange OKX and blockchain technology company Polygon Labs have announced the launch of a jointly developed zero-knowledge L2 network called "X1" testnet, with OKB as the native token.

ZK L2 "X1" Testnet, OKB to Become Native Token

This partnership will see OKB, the native token of the OKX platform, used for paying transaction fees on the X1 network.

The initiative aims to enhance the scalability and security of the Ethereum blockchain while reducing transaction costs. The network will be Ethereum-compatible, providing developers with the convenience to build Web3 applications and achieve interoperability with other blockchains and ecosystems. Attention in the crypto market will focus on the price changes of the OKB token, which has risen by 23% in the past seven days, with a price of $62.53 at the time of writing.

Polygon Labs Launches ZK L2 Development Tool

Prior to this collaboration, Polygon Labs introduced in August a Layer 2 blockchain development tool for developing zero-knowledge proof (ZK)-driven L2 blockchains, known as the "Polygon Chain Development Kit" (CDK). Polygon stated that L2 deployments using the Polygon CDK will be able to connect to shared ZK bridges to achieve interoperability.

Sandeep Nailwal, co-founder of Polygon, mentioned that X1 represents a significant advancement in the application of Polygon CDK technology, and more ZK-driven L2 blockchains will achieve interoperability and coexist within the Polygon CDK ecosystem in the future. Several L2 blockchain projects have already started development using the Polygon CDK, including Immutable zkEVM, IDEX, Palm Network, and Astar zkEVM.
