According to official news, Arkham Intel Exchange announced the upgrade of Chainlink Function. After integrating Chainlink's industry-standard oracle solution, an additional decentralized layer will be added between Arkham and smart contracts. This integration replaces the existing centralized oracle solution with a decentralized oracle network. Chainlink Functions is a serverless developer platform for obtaining data from any API, running custom JavaScript-based calculations on that data using Chainlink's network, and passing the results back to smart contracts.
