# Course Introduction Welcome to the **ULTIMATE** Chainlink Fundamentals course! ## What is the Chainlink Fundamentals course? This comprehensive course covers all major Chainlink services: - Chainlink Data and Price Feeds - Chainlink Automation - Chainlink CCIP - Chainlink Functions - Chainlink VRF - Chainlink Data Feeds - Chainlink Proof of Reserve Each service has a dedicated section structured as follows: - A high-level overview explaining the service and its functionality - A practical Solidity project providing hands-on experience - A detailed code breakdown for developers showing how to integrate the service **Note for Non-Developers**: This course is designed for everyone! If you're not a developer, you don't need to master all the technical details. Each section introduces a Chainlink service with: 1. A non-technical, high-level explanation of what it is and how it works 2. A hands-on project demonstrating the service 3. Optional code breakdowns that you can either study in detail or copy-paste to proceed The projects reinforce your understanding of each service rather than training you as a Chainlink developer. However, aspiring developers should carefully review the complete code breakdowns. ## Prerequisites ### Required Before taking this course, you must have completed [**Blockchain Basics**](https://updraft.cyfrin.io/courses/blockchain-basics) to understand: - What a blockchain is - The distinction between L1s and L2s - What blockchain oracles are from a high-level - MetaMask wallet creation and management - Using cryptocurrency faucets - Navigating block explorers (like Etherscan) - Adding new networks to MetaMask - Understanding blockchain gas mechanics ### Recommended We recommend completing the [**Solidity Smart Contract Developer**](https://updraft.cyfrin.io/courses/solidity) course before this one. While not mandatory (Section 2 covers Solidity fundamentals), that course provides a more comprehensive foundation. This course offers a condensed overview of Solidity. ## Who is this course for? This course is designed for: - Non-technical web3 professionals (sales, business development) - Solutions architects - Developers (both beginner and experienced) We only assume knowledge from the Blockchain Basics course. All code examples can be copied and pasted, and Solidity concepts are explained step-by-step. You don't need any prior programming experience, and the course adapts to your learning needs and preferences.
