Key terms

Solidity

The dominant smart contract programming language for Ethereum and EVM-compatible chains. Most in-demand blockchain development skill. Free resources include Cyfrin Updraft (with 50+ hours of security content, 6M+ views).

Rust

Systems programming language used by Solana, Near, Aptos, and Polkadot. Steeper learning curve than Solidity but commands premium pay.

Move

Smart contract language used by Sui and Aptos, designed by former Facebook (Diem) engineers. Resource-oriented programming model.

Foundry

Modern Solidity testing framework, replacing older tools like Hardhat and Brownie for many use cases. Documentation at book.getfoundry.sh.

Cyfrin Updraft

Patrick Collins' free comprehensive Solidity and security curriculum at cyfrin.io/updraft. Includes 50+ hours of Solidity security content described as the most-watched Solidity course with 6M+ views.

CryptoZombies

Long-running interactive Solidity tutorial with 400,000+ users. Builds skills by walking learners through creating a zombie game.

BuildSpace

Project-based learning platform with 60,000+ builders. Short courses where learners build real projects (NFT collections, DeFi applications, etc.) over a few weeks.

Patrick Collins YouTube course

Free 32-hour Solidity course on YouTube, one of the highest-quality free educators in the space.

Web3 development stack

Modern JavaScript/TypeScript libraries for blockchain frontends: ethers.js (and viem), wagmi (React hooks), WalletConnect, The Graph. Many crypto product engineering roles are essentially "React developer with Web3 knowledge."

Dune Analytics

Dominant tool for blockchain SQL queries. Data analysts use Dune to query on-chain data and build dashboards. Strong career path for people who know SQL.

Zero-knowledge cryptography (ZK)

Advanced specialization with very small talent pool and premium pay. Skills include understanding circuits, proof systems (Groth16, Plonk, STARKs). Resources like 0xPARC and ZK Hack are starting points.
