Blockchain oracle network Chainlink has announced a collaboration with Ethereum layer-2 scaling protocol Arbitrum to facilitate the development of cross-chain decentralized applications (DApps). The partnership will bring the Chainlink Cross-Chain Interoperability Protocol (CCIP) to the mainnet of Arbitrum One, offering developers access to Chainlink’s solution while leveraging Arbitrum’s high-throughput, low-cost scaling capabilities.
The integration of CCIP and Arbitrum One aims to unlock various use cases in the blockchain space. These include cross-chain tokenization and collateralization, blockchain gaming, data storage, and computation. By offloading transaction congestion from Ethereum’s base layer, Arbitrum’s technology provides a reliable foundation for building DApps, while Chainlink’s time-tested infrastructure ensures secure and easy-to-use cross-chain smart contracts.
Arbitrum’s optimistic rollup technology, which currently dominates around 60% of the total value locked in the Ethereum layer 2 ecosystem, will be combined with CCIP. This technology facilitates efficient transactions through off-chain batching, which are then submitted to Ethereum’s base layer. The optimistic rollup operates under the assumption of validity, which can only be disproven by validators of the network.
CCIP enables developers to create cross-chain DApps that utilize arbitrary messaging and simplified token transfers. This functionality relies on Chainlink’s decentralized oracle network, which allows smart contracts to securely access off-chain data sources, APIs, and payment systems. In effect, smart contracts can interact with real-world data and events, enabling them to be triggered by external sources.
