Event: Devcon
Date: Jul 2026
Jeffrey, the founder of Rare Skills, explains effective Web3 learning for advanced developers. He contrasts Exploration Learning (building projects immediately) with Hierarchical Learning (mastering fundamental, generalizable skills first). He advocates for the hierarchical method, emphasizing that internalizing core concepts (like ERC20, cross-contract calls, and binary math) is essential for quickly achieving fluency and understanding complex DeFi protocols like Uniswap. The presentation introduces Rare Skills as an advanced, fundamentals-first educational platform.curriculum.
