Nervos’ L2 Polyjuice Integrates with Band Protocol to Foster dApps Ecosystem

This post was originally published on bandprotocol

We are excited to announce that Band Protocol and Nervos Network have completed another milestone: Band Oracle is now live on Polyjuice testnet, a layer 2 solution on top of Nervos CKB, after integrating successfully onto their layer one. This partnership is a further step in completing the shared vision of a secure and scalable DeFi ecosystem.

Polyjuice is an Ethereum Virtual Machine (EVM) compatible with the design for scalability in focus. The infrastructure enables easy deployment of any Ethereum dApp on the network to allow for fast ecosystem growth. By integrating with Band Protocol, the projects in the Polyjuice ecosystem now have an access to request Band Oracle data from Band Standard Dataset which contains 230+ symbols, spanning over various foreign currencies, cryptocurrencies, stocks, and more.

The price feed will be critical for decentralized applications, especially DeFi applications, which rely on various real-world data of prices and more to build services in various segments ranging from money-market, lending, derivatives, decentralized exchanges, to insurance.

End-to-End Customization, Endless Possibility

With Bandchain’s infrastructure, the possibility of development on Polyjuice ecosystem is vast. Developers on Polyjuice can customize their oracle solutions by creating their own oracle scripts which specify any external source or APIs to use and designing their own custom parameters for aggregation, update time, and validator confirmations. With this level of flexibility along with the time-tested history of Band Protocol’s Oracle service, Polyjuice is well-positioned to be a nurturing ecosystem for future dApps.

Co-founder of Nervos, Kevin Wang, said of this integration:

“One of our primary goals is to make building dApps on Nervos easy and exciting, as well as allow those apps to be flexible and powerful. This extension of our partnership with Band means we can offer a well-established oracle service that developers can use in building out our DeFi sector, as one key example. We hope that developers will make use of this oracle service when building on CKB, or, join us from Ethereum with the simple process of porting over.”

About Nervos Network
The Nervos Network is an open source public blockchain ecosystem and collection of protocols solving the biggest challenges facing blockchains like Bitcoin and Ethereum today. The Nervos CKB (Common Knowledge Base) is the layer 1, proof of work public blockchain protocol of the Nervos Network. It allows any crypto-asset to be stored with the security, immutability and permissionless nature of Bitcoin while enabling smart contracts, layer 2 scaling and captures the total network value through its “store of value” crypto-economic design and native token, the CKByte.

About Band Protocol
Band Protocol is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. Blockchains are great at immutable storage and deterministic, verifiable computations — however, they cannot securely access data available outside the blockchain networks. Band Protocol enables smart contract applications such as DeFi, prediction markets, and games to be built on-chain without relying on the single point of failure of a centralized oracle. Band Protocol is backed by a strong network of stakeholders including Sequoia Capital, one of the top venture capital firms in the world, and the leading cryptocurrency exchange, Binance.
