Start your blockchain developer journey with Track 1: Blockchain Foundations & Smart Contracts, the first course in the From Blocks to Build: Blockchain Dev Essentials specialization. This track teaches the core ideas that make decentralized systems work—distributed ledgers, consensus, transaction mechanics—and brings you inside the Ethereum Virtual Machine to build practical Solidity skills.

You’ll write, test, and deploy smart contracts using Remix IDE and EVM testnets, complete guided coding labs, and check your progress with auto-graded quizzes and hands-on exercises. Lessons focus on reliable contract structure, gas and execution flow, and common pitfalls to avoid when designing on-chain logic. This is the technical foundation: by the end you’ll be able to create EVM-compatible contracts, reason about transaction behaviour, and apply secure coding patterns. Track 1 is the first of three sequential tracks—followed by DApps & Tokenization Tools and Enterprise Blockchain & Auditing—that together form the full specialization. Complete all three tracks, finish the capstone, and pass the final proctored exam to earn the specialization’s industry-recognized certification.
