Flow Workshop - Fast Track Your Onchain App I b z

Thu, Oct 2, 2025, 12:00 AM

This Flow Workshop, led by BC Devil from the Flow Foundation at ETHGlobal, introduces developers to building fast, scalable, and user-friendly onchain apps using the Flow blockchain. The session highlights Flow’s origins (from the CryptoKitties team), its unique architecture solving the blockchain trilemma (scalability, decentralization, security), and its dual support for EVM and Cadence smart contracts. Key features include native account abstraction, gasless experiences, sub-4s finality, and onchain randomness. The workshop demonstrates deploying a Solidity contract on Flow EVM, integrating with tools like MetaMask and Remix, and building a frontend using AI coding assistants. Flow’s ecosystem is trusted by major brands (NBA Top Shot, Disney, Ticketmaster), supports crosschain DeFi via bridges like LayerZero, and offers developer resources, bounties, and ongoing grants. The session encourages innovation, leveraging Flow’s advanced features for killer apps and seamless user experiences. 00:00 Introduction 00:09 Why Build on Flow? 01:00 CryptoKitties and Blockchain Scaling Challenges 02:17 Developer Experience and Smart Contract Languages 02:47 Building Flow: Origins and Vision 03:10 Flow’s Unique Architecture and Features 04:09 EVM Compatibility and Cadence 05:02 Flow’s Ecosystem and Major Partners 05:25 Solving the Blockchain Trilemma 06:21 Flow’s Node Roles and Scalability 06:48 ETHGlobal Bounties and Tracks 07:10 Killer Apps and Historical Examples 08:22 Ideation and Inspiration 08:49 Crosschain DeFi on Flow 09:13 Onchain Randomness Demo 10:11 Setting Up MetaMask and Flow Testnet 11:10 Deploying and Testing Smart Contracts 11:32 Building the Frontend with AI Tools 12:19 Debugging and Configuration 13:18 Finalizing and Testing the App 13:43 Developer Resources and Tooling 14:37 Cadence Features and Advanced Use Cases 15:11 Developer Support and Community 15:39 Judging Criteria and Grants 16:34 CryptoKitties Legacy and Encouragement 16:55 Q&A and Closing Remarks _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *ETHGlobal Cannes* This workshop is specifically for ETHGlobal Cannes, a 3-day hackathon held July 4-6, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
