In this workshop at ETHGlobal New York 2026, Nalin Mittal and Goutham Deva from Google Cloud's Web3 team present building for the on-chain agent economy, centered on ERC-8004 and accessing its data through BigQuery. Nalin, who leads Web3 product efforts, notes Google Cloud has built Web3 products since 2018, with BigQuery datasets for over 40 blockchains, faucets for many test networks, and growing agentic access. He frames the core problem: as agents gain autonomy and begin purchasing from and delegating to other agents, real-time markets will form on the fly, but you cannot extend trust across organizational boundaries without knowing who you are dealing with. Standards like MCP (for tools and services) and Google's A2A (agent-to-agent communication) exist, but the trust piece is still missing, and ERC-8004 bridges that gap. Goutham and Nalin explain that ERC-8004, built in collaboration with MetaMask, the Ethereum Foundation, and Coinbase and live on Ethereum mainnet since January 29 (and other chains), establishes three pieces. Identity: calling a register event mints an NFT tied to the agent and returns an agent ID, with the metadata holding a name, description, and most importantly the service endpoints (A2A, MCP), whether it supports x402, and which trust models it uses. Reputation: a give-feedback contract method lets anyone leave on-chain, public feedback (star ratings, uptime, response times) via open-ended tags. Validation: still a work in progress, a way to prove an agent did the work it claimed via a third-party validator and hash. They then show how to access the 8004 data through Google's BigQuery Ethereum dataset (indexed from genesis to chain tip, with a generous 1 TB free tier plus a $1,000 coupon for the track), walking through live SQL queries for registrations per day, decoding a register event, a reputation leaderboard, and an x402 join showing which agents support x402. Nalin lays out the $5,000 cash prize for applications leveraging the identity and reputation data (like an explorer or analytics dashboard), and closes with Q&A on monetization (none, it is an open registry), available datasets like Base, how feedback works, spam, and whether the spec extends beyond agents. 00:00 Introduction 00:11 Meet Nalin and Google Cloud Web3 00:54 Meet Goutham 01:16 How the Workshop Is Structured 01:40 The $5,000 Prize 02:01 Why Agents Need Trust 02:23 Delegation and Real-Time Agent Markets 02:41 MCP, A2A, and the Missing Trust Piece 03:39 Trusting Agents Across Organizations 04:01 The Three Pieces of ERC-8004 04:36 Built With MetaMask, EF, and Coinbase 04:54 Identity: Registering an Agent 05:34 What the Agent File Contains 05:55 Service Endpoints and x402 Support 06:18 Reputation: Giving Feedback 06:39 Why Tags Are Open-Ended 07:05 Building a Reputation System 07:15 Validation: Proving Work Was Done 07:58 The Identity and Reputation Registries 08:21 The BigQuery Ethereum Dataset 08:47 The Free Tier and $1,000 Coupon 09:30 How to Set Up Access 10:14 Walking Through Live Queries 11:29 Understanding the Dataset Fields 11:50 Query: Registrations Per Day 12:24 Query: Decoding a Register Event 13:12 Reading the Agent URI 13:58 Decoding Input Data on the Contract 14:22 Query: Reputation Leaderboard 14:52 Query: The x402 Join 15:55 More on the Prize 16:15 What a Winning Application Looks Like 17:01 Where to Find Resources 17:24 Q&A: Plans to Monetize 8004 18:11 Q&A: Datasets for Base and BNB 18:41 Q&A: What Is 8004 19:36 Q&A: Interesting Findings in the Agents 19:52 Q&A: How Leaving Feedback Works 21:00 Q&A: Judging and Spam 22:00 Q&A: Does the Spec Go Beyond Agents 23:11 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHGlobal New York 2026* This workshop is specifically for ETHGlobal New York 2026, a 3-day hackathon held June 12-14 at the Metropolitan Pavilion, 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!

Kevin Jones

ETHGlobal · Aug 9, 2026

In this workshop at ETHGlobal New York 2026, Kevin Jones from BuidlGuidl walks hackers through building on Ethereum in the AI era, tying together the tools and best practices that let developers learn and ship faster. Having worked in the Ethereum ecosystem for about six years alongside Austin Griffith and the Ethereum Foundation, he surveys what BuidlGuidl has produced for developer education and tooling. He gives a tour of SpeedRun Ethereum, the challenge-based curriculum that teaches core concepts through hands-on modules: minting an NFT, crowdfunding and staking, ERC-20 tokens and the approve pattern, a dice game on on-chain randomness, building a DEX with liquidity pools, oracles, overcollateralized lending, stablecoins, prediction markets, and zero knowledge, plus capture-the-flag security events and a new AI-guided learning mode. He also covers other BuidlGuidl products including Scaffold-ETH, ABI Ninja, Address Vision, and its full node client. Kevin then dives into AI-era building. He explains x402 (Coinbase's extension of the HTTP 402 status code) as a way to token-gate any API with an onchain payment instead of API keys, noting his work at Edge & Node (creators of The Graph) on a wallet that makes and accepts x402 payments with guardrails. He highlights ETH skills, an open source skill file encoding Ethereum best practices for editors like Claude Code, Cursor, and Codex, and ERC-8004, a registry giving AI agents a long-lived onchain reputation (with Agent0's SDK and a subgraph for querying agents). He shares his AI coding workflow: ideate in Claude Desktop to generate a prompt, bootstrap in Claude Code, then move to Cursor to review diffs. He runs a live Scaffold-ETH demo, spinning up a project with two commands, explaining the Hardhat and Next.js monorepo, burner wallet, auto-generated ABI-driven debug UI, hooks, and components (ENS resolution, balance checkers), then vibe-codes a basketball NFT contract that deploys and mints a LeBron card. He closes on OneClaw, his spotlight secrets-management platform storing keys in a Google Cloud HSM with multi-party computation, an LLM proxy running in a TEE that inspects prompts for injection and redacts secrets, and intent-based signing with guardrails so an agent can use a key that never leaves hardware, followed by Q&A. 00:00 Introduction 00:13 Nostalgia for ETHGlobal New York 00:32 About Kevin and BuidlGuidl 01:00 Why AI Accelerates Learning and Building 02:15 Introducing SpeedRun Ethereum 02:46 Scaffold-ETH as a Starter Kit 03:45 A Walk Through SpeedRun Challenges 04:40 ERC-20 Tokens and the Approve Pattern 05:09 The Dice Game and On-Chain Randomness 05:35 Building a DEX and Liquidity Pools 06:20 Oracles and Overcollateralized Lending 07:13 Stablecoins and Prediction Markets 08:28 Learning Zero Knowledge 08:58 The Tech Tree and Capture the Flag 10:15 The New AI-Guided Learning Mode 11:06 What Is x402 11:31 How x402 Token-Gates APIs 12:56 Building on x402 With Edge & Node 13:44 ETH Skills for Your Editor 15:06 ERC-8004: A Registry for AI Agents 16:05 Building Agent Reputation 16:42 Agent0 and the Subgraph 18:28 Kevin's AI Coding Workflow 19:12 Starting Ideation in Claude Desktop 21:18 Generating a Prompt for Claude Code 23:36 Moving to Cursor to Review Diffs 24:39 Starting a Scaffold-ETH Project 26:22 Choosing Hardhat or Foundry 29:18 Agent, Plan, and Ask Modes 30:45 Inside the Scaffold-ETH Monorepo 31:36 The AI-Friendly Files and MCP Server 34:00 The Burner Wallet and Debug UI 35:00 How the ABI Powers the Front End 35:58 Vibe-Coding a Basketball NFT Contract 40:19 Minting a LeBron NFT 41:27 The BuidlGuidl Full Node Client 42:20 Introducing OneClaw Secrets Management 43:18 The LLM Proxy in a TEE 44:36 Intent-Based Signing With Guardrails 45:39 Embedded Wallets, MCP, and SDK 46:30 Q&A: Signing Latency 47:49 Q&A: Git Integration for Agents 49:12 Q&A: How ERC-8004 Reputation Works 52:44 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHGlobal New York 2026* This workshop is specifically for ETHGlobal New York 2026, a 3-day hackathon held June 12-14 at the Metropolitan Pavilion, 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!

Kartik Talwar

ETHGlobal · Aug 9, 2026

In this welcome and opening ceremony, Kartik Talwar, co-founder of ETHGlobal, opens ETHGlobal New York 2026, stressing that this is not a conference but a hackathon whose mission is to onboard thousands of developers into the web3 ecosystem. He explains what makes ETHGlobal events different: a focus on builders, a place to learn and grow, and the belief that showing beats telling, so on Sunday everyone demos what they built. He traces ETHGlobal's history from a small 2017 hackathon (where NFTs were invented) through global expansion across six continents, noting that counting the recent ETHConf, they have run over 331 events in eight and a half years, hosted 165,000 people from 156 countries, produced 18,000+ hackathon projects, and seen projects raise over $500 million. This weekend brings almost 700 attendees (close to 500 hackers, 30% new to web3), plus supporting staff, 17 mentors, 20 recorded workshops, zero talks, over $200,000 in prizes, and 16 sponsors. Kartik walks through key logistics and rule changes. Hacking begins immediately, teams can have up to five members, and submissions are due Sunday at 9am. On AI, he encourages using tools like Cursor, Claude Code, and Codex but warns from thousands of data points not to use AI to generate or validate your idea (crypto bias is real), to keep a human in the loop, to reference-check SDK integrations, to commit plan files, and to always know what your codebase does. He introduces the new continuity track, letting hackers build from scratch, extend an open source project, or ship a feature into existing or private code, as long as new work stays open source and traceable via the GitHub API, with track-specific prizes. He covers venue security, Wi-Fi etiquette, the website as source of truth, Discord support, four spotlight teams (Aquazero, CodeQuil, Pompalo, Railbridge), and judging: partner-prize demos plus an add-on finalist track for the top 10 teams (up to seven scratch, three continuity) requiring an auditable open source repo, a live deployed site, and a video demo, with finalist perks including ETHGlobal Plus, $1,000 per member, travel, and developer credits. He closes by bringing on partners Tanner from 1inch (Aqua self-custodial AMMs), Gotham from Google Cloud Web3 (ERC-8004 data track), and Greg from ENS (naming as universal pointers), before telling everyone to get hacking. 00:00 Introduction 00:40 What Makes ETHGlobal Events Different 01:03 The History From 2017 to Today 01:49 Expanding Across Six Continents 02:18 The Numbers: 331 Events and Counting 02:44 18,000 Projects and $500 Million Raised 03:47 Mentors, Workshops, and Sponsors 04:27 Thanking the Sponsors 05:01 Logistics: Hacking Begins Now 05:19 The New Rules: Teams and Timing 05:37 Guidance on Using AI to Build 06:12 Explaining Your Contribution vs Delegation 07:11 Why Not to Use AI to Generate Ideas 07:38 Why Not to Use AI to Value Your Idea 08:33 Why Not to Blindly Delegate SDK Integrations 08:56 Always Know What Your Codebase Does 09:43 Introducing the Continuity Track 10:49 The Three Paths You Can Take 11:28 How Extending Open Source Works 12:43 Adding Features to Your Own Project 13:27 Adding a Module to Private Code 14:58 Why Prizes Are Track Specific 15:44 Venue Security and Wristbands 16:39 Wi-Fi 7 and Why Not to Use Hotspots 17:52 The Website and Discord Support 18:53 Food, Activities, and Swag 19:26 The Four Spotlight Teams 20:13 Judging and the Prize Structure 21:03 The Partner Prize Track 21:22 The Finalist Track for the Top 10 21:45 Finalist Perks and Requirements 23:45 Splitting Finalists Across Tracks 24:14 Submission Logistics and Timing 25:54 Why a Better Submission Wins 26:57 Where to Get Help From Mentors 27:40 Code of Conduct and IP Ownership 28:51 Tanner From 1inch on Aqua 31:00 Gotham From Google Cloud on ERC-8004 33:19 Greg From ENS on Naming 35:41 Summarizing the Prizes 36:23 Final Advice and Let's Get Hacking _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHGlobal New York 2026* This workshop is specifically for ETHGlobal New York 2026, a 3-day hackathon held June 12-14 at the Metropolitan Pavilion, 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!

ETHGlobal · Aug 9, 2026

In this workshop at ETHGlobal Lisbon 2026, Gathin T, a senior developer at 0G, introduces 0G as a permissionless blockchain for AI agents, covering what it is, how to start building, and the resources available. He frames the core value up front: 0G enables verifiable, private inferencing where model queries run inside a trusted execution environment (TEE) so the input and output are verified and not exposed to centralized entities. He then walks through the problems with centralized AI. Recent restrictions and re-enablements around Fable Fi show how access can be throttled, gated, or removed by government or corporate decisions. Subscription pricing can change unpredictably (he cites region-specific pricing). Censorship can refuse legitimate requests (like cybersecurity research) based on a model's parameters. He breaks these into specific issues: opacity and lack of trust (you cannot verify you are getting the actual model behind a black box), vendor lock-in with closed APIs and shifting policies, and no true ownership of the agents you create. Gathin explains how 0G addresses each. Inference is provable with references, running in a tamper-proof input-output channel where your data is not used for training. Rather than lock-in, 0G is a marketplace where you can switch between multiple providers for the same model, choosing cheaper or lower-latency options by region. Ownership comes via agentic IDs (the ERC-7857 standard), NFTs tied to an agent that can be transferred. He stresses the platform is permissionless with no gatekeeper, and that its modular stack lets you swap any layer without rebuilding, with incentives for compute providers and future fine-tuning contributors. He notes open source models like Kimi K2, GLM, and DeepSeek are reaching parity, and covers the architecture: an infinitely scalable chain (11,000 TPS, sub-second finality), decentralized storage (80 to 90% cheaper than AWS S3), compute, a soon-launching fine-tuning and RAG layer, a provider marketplace, and alignment nodes (around 92,000 sold) giving the community governance. He highlights products like the private compute router at pc.0g.ai (OpenAI-compatible keys) and the 0G app for building, notes 0G is well funded ($325 million) with 400+ ecosystem partners, and closes with the $15,000 in bounties across best AI product, infrastructure, and continuity tracks, plus a Telegram group for testnet tokens, followed by Q&A. 00:00 Introduction 00:33 Welcome to Lisbon 00:44 What This Workshop Covers 01:04 The Core Problem With Centralized AI 01:25 Verifiable, Private Inference in a TEE 01:49 How Centralized Models Get Restricted 02:07 Unpredictable Subscription Pricing 02:45 The Censorship Problem 03:04 Opacity and the Black Box Problem 03:45 How 0G Enables Verifiable Inference 04:13 Vendor Lock-In and Switching Providers 04:58 The Problem of No Agent Ownership 05:17 Agentic IDs as Ownership 05:37 Centralized Control and Censorship 06:18 Swapping Layers Without Rebuilding 07:01 Incentives Across the Modular Stack 07:38 Why Open Source Models Are Catching Up 08:01 Private TLS Routing and Attestation 08:58 The Modular Architecture 09:18 Decentralized Storage for Agents and Models 09:56 The Marketplace and Alignment Layer 10:25 Why Trust Is the Biggest Issue 10:53 0G Compute and GLM 11:16 Storage 80 to 90% Cheaper Than S3 11:38 Chain Throughput and Sunsetting the DA 12:00 Agentic ID and the ERC-7857 Standard 12:12 The Private Compute Router 12:42 The 0G App and Agent Launchpad 13:02 Funding, Partners, and Grants 13:26 The $15,000 in Bounty Tracks 13:47 The Infrastructure Track 14:07 The Continuity Track 14:25 Joining the Telegram for Testnet Tokens 15:02 Q&A: Track Ideas and Requirements 15:57 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇵🇹 *ETHGlobal Lisbon 2026* This workshop is specifically for ETHGlobal Lisbon 2026, a 3-day hackathon held July 24-26 at the Carlos Lopes Pavillion, 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!

Kevin Jones

ETHGlobal · Aug 9, 2026

In this workshop at ETHGlobal Lisbon 2026, Kevin Jones from BuidlGuidl (who also works at Edge & Node on The Graph protocol and supports the Ethereum Foundation) walks through building apps on Ethereum in the AI era, covering the key tools and then live-building an app. He introduces BuidlGuidl, created by Austin Griffith, and its flagship learning product SpeedRun Ethereum, a set of challenges that validate your understanding of the protocol across NFTs, crowdfunding, the token vendor and ERC-20 patterns, on-chain randomness and oracles, building a DEX with liquidity pools, oracles, over-collateralized lending (like Aave) and liquidations, stablecoins, and newer guides on prediction markets and ZK voting, plus capture-the-flag events and the ETH tech tree. He then covers Scaffold-ETH, the starter kit that was his own introduction to Ethereum, now launchable with a single command (npx create-eth) that bootstraps a full dApp: smart contract, local chain, and a Next.js front end with pre-written components and hooks, all wired together and made AI-friendly by default. Kevin highlights ETH skills (at ethskills.com), an open source collection of Ethereum best-practice skill files (for smart contracts, code reviews, censorship resistance, privacy, and more) that you add to your coding agent so it builds the best app it can. He live-demos scaffolding a project called Lisbon, explaining the choice between Foundry and Hardhat, splitting the terminal into windows for the chain, front end, and deploys, and how the yarn commands and pre-written scripts simplify setup. He shows how Scaffold-ETH parses the deployed contract's ABI into front-end types and an auto-generated debug UI, plus a built-in burner wallet and faucet that avoid MetaMask nonce issues on a local chain. He debugs a dependency error live (recommending copying the error to the AI and using Opus 4.6 for prototyping), then vibe-codes the starter contract into a basic lottery, showing how the bundled .agents, .claude, and .cursor skill folders automatically load BuidlGuidl's best practices (contributed by members like Carlos) so the agent adds ownable, a reentrancy guard, buy-ticket and pick-winner functions, and updates the front end. He tours reusable components (ENS resolution, address inputs, balance and ether inputs) and read and write hooks, and closes with Q&A on ETH skills folders, simulating time on a local chain, and testing in Foundry versus Hardhat. 00:00 Introduction 00:11 Meet Kevin and His Workshops 00:30 Building on Ethereum in the AI Era 00:48 Who Has Used Scaffold-ETH 01:07 Introducing BuidlGuidl and SpeedRun Ethereum 01:56 The Token Vendor and ERC-20 Patterns 02:18 Randomness and Oracles 02:31 Building a DEX and Liquidity Pools 02:48 Over-Collateralized Lending and Liquidations 03:30 Stablecoins, Prediction Markets, and ZK Voting 03:50 Capture the Flag and the ETH Tech Tree 04:14 What Scaffold-ETH Is 04:44 One Command to Bootstrap a dApp 05:24 Introducing ETH Skills 06:17 A Tour of Scaffold-ETH and the Docs 07:12 Why the Pre-Written Front End Helps 07:44 Starting the Project With create-eth 08:29 Choosing Foundry or Hardhat 09:27 Splitting Your Terminal Into Windows 10:09 Why Kevin Uses Cursor 10:33 The Commands to Get Set Up 10:58 Starting the Local Chain 12:04 Deploying the Starter Contract 12:54 How the ABI Powers the Front End 13:47 Loading Up Scaffold-ETH 14:14 Debugging an Error With AI 15:40 The Built-In Burner Wallet and Faucet 16:13 The Debug Contracts Tab 17:05 The Chain Folder and Skill Files 17:57 How the Bundled Skills Work 18:40 Best Practices From the BuidlGuidl Team 19:24 Vibe-Coding a Lottery Contract 20:13 Deploying the AI-Written Changes 20:37 Updating the Front End 20:55 Q&A: Where to Find ETH Skills 21:49 A Tour of the Reusable Components 22:38 The Read and Write Hooks 23:58 Testing the Lottery Page 24:52 Q&A: Testing in Foundry vs Hardhat 25:34 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇵🇹 *ETHGlobal Lisbon 2026* This workshop is specifically for ETHGlobal Lisbon 2026, a 3-day hackathon held July 24-26 at the Carlos Lopes Pavillion, 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!

Kartik Talwar

ETHGlobal · Jul 9, 2026

In this fireside chat, Kartik Talwar from ETHGlobal sits down with Katherine Wu, CEO of ENS Labs, to discuss the next era of ENS. Katherine explains that ENS launched in 2017 before NFTs, DeFi, L2s, account abstraction, and stablecoins existed, and that its smart contracts reflect a very different world. V2 is a ground-up rearchitecture of both the protocol and the front-end apps to meet users in a fast-changing, multi-chain industry. On the protocol side, V2 gives users maximal flexibility to design and set rules for their own namespaces in a world of stablecoins and L2s. On the app side, ENS is splitting its front end into two experiences: an Explorer for data nerds who want to see a name's full onchain history and footprint, and a simpler app for casual users who just want a profile. Katherine walks through the decision to abandon Namechain, ENS's planned own L2, which was not easy. The original motivation was sparing users the volatile, high mainnet gas fees of 2021 (she paid over $300 to register her name), but over the past year mainnet registration gas fell roughly 100x from around $5 to five cents, invalidating the core assumption. Since a name tied to identity needs the strongest security guarantees, and Ethereum L1 is the most secure chain with no downtime, they prioritized V2 on mainnet instead. She describes her role as CEO of an engineering-driven org, spanning finance, operations, and deep technical dives, and how working with the DAO forces user-first decisions (they put a first-ever price increase to a DAO vote and cannot unilaterally ship a protocol upgrade without token holder approval, a can't-be-evil design). She highlights ENS integration in PayPal and Venmo for sending stablecoins by username rather than a 0x address, arguing fintechs bringing users on chain cannot ship a 2017 UX. She previews V2 letting users pay for names with stablecoins or any ERC20 token, even starting the transaction on any L2 and settling on mainnet, and discusses years of good-faith relationship building with ICANN toward DNS compatibility (contrasting ENS with unrecognized alt-naming projects like .crypto that sit outside the internet root zone). She closes on the hardest part of building a trustless protocol with millions of users and owned assets: you cannot move fast and break the internet, and V2 is like ENS's version of the merge. 00:00 Introduction 00:11 The Next Era of ENS and Why V2 00:41 Why ENS Is Still Around Since 2017 01:07 How the Crypto World Has Changed 01:32 A World Before DeFi, L2s, and Stablecoins 02:04 The Big Features of V2 Over V1 02:33 Maximal Flexibility on the Protocol Side 02:56 Splitting the App Into Explorer and Normal 03:37 The Namechain Announcement 03:53 What Namechain Was and Its Goals 04:20 Maximizing Trustlessness 04:41 The $300 Gas Fee Problem of 2021 05:03 Why ENS Looked Into L2s 05:29 How Mainnet Gas Fell 100x 06:02 Why Security Guarantees Matter Most 06:21 Why Ethereum L1 Won 06:57 What the CEO of ENS Labs Actually Does 07:38 Why the Open Engineering Culture Matters 08:00 VC vs the Operating Side 08:22 How ENS Works With the DAO 08:53 Asking Users Before Raising Prices 09:29 Why Protocol Upgrades Need a Vote 09:53 The Can't-Be-Evil Design 10:13 ENS in PayPal and Venmo 10:57 Why Fintechs Integrated ENS for Stablecoins 11:51 The Security Case Against Raw Addresses 12:36 Why On-Chain Products Cannot Ship 2017 UX 12:59 Optimizing How You Pay for a Domain 13:15 Why ENS Was Not Built for ERC20 Payments 13:44 Buying an ENS Name With Any ERC20 Token 14:04 Starting the Transaction on Any L2 14:27 Compatibility With DNS and TLDs 14:59 Why ICANN Matters 15:37 Why Alt-Naming Projects Fall Outside the Root Zone 16:10 Years of Building Relationships With ICANN 16:58 The Hardest Part of Building Trustless Protocols 17:26 Why the Protocol Does Invisible Work 17:55 Why You Cannot Move Fast and Break the Internet 18:25 Designing for Every Edge Case 18:58 Why V2 Is ENS's Version of the Merge 19:16 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHConf 2026* ETHConf is a 3 day event for founders, industry leaders, and builders who are excited about the possibilities of building on top of Ethereum.

ETHGlobal · Jun 9, 2026

In this workshop, Ed Marquez walks through the three foundational layers needed for a trustless agentic economy: identity (ERC-7804), communication (Google's A2A protocol now under the Linux Foundation), and payments (X2X). He frames the vision of a near-future agentic web where AI agents discover, communicate with, and pay each other autonomously, and demonstrates how these three open protocols together enable that economy. Ed does live coding demos showing each layer. For A2A, he shows how agents expose an agent card describing their skills, capabilities, and streaming support. For X2X, he demonstrates how just 15 lines of middleware can gate any Express endpoint behind stablecoin micropayments, using Cloudflare's pay per crawl initiative with publishers as a real world example. He walks through the facilitator architecture that separates blockchain execution from business logic, then combines A2A with X2X to create an AI agent that charges 1/10th of a cent per stock summary query. For ERC-7804, he covers the three registries: identity (NFT-based), reputation (score-based feedback with optional IPFS or HCS-stored details), and validation, explaining how server agents authorize clients to leave signed feedback, creating verifiable reputation that lets autonomous agents safely discover and trust each other. 00:00 Introduction 00:11 Three Pillars of the Agentic Economy 02:26 Technologies: ERC-7804, A2A, X2X 02:49 GitHub Repo Walkthrough 03:33 A2A Agents and Agent Cards 05:14 A2A Client Setup 06:00 Introduction to X2X Protocol 07:12 X2X for Micropayments and Pay Per Crawl 08:19 Implementing X2X Middleware 10:00 Combining A2A with X2X Payments 11:47 X2X Facilitator Architecture 13:33 Client Side X2X Integration 15:30 Live Demo: AI Agent with Paid A2A Endpoint 17:14 Verifying the Transaction on Hashscan 17:54 The Trust Problem in Autonomous Agents 19:46 Introduction to ERC-7804 20:58 The Three Registries: Identity, Reputation, Validation 22:23 Validation Registry Explained 23:16 Live Demo: Registering an Agent on ERC-7804 24:38 Minting the Identity NFT 25:54 Setting Agent Metadata and Trust Mechanisms 27:47 Reputation Feedback Flow 28:39 Authorizing Feedback with Signed Tokens 29:34 Feedback URIs: IPFS vs Hedera Consensus Service 31:20 Closing and Discord Call to Action _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ✅ *Follow ETHGlobal* X: https://x.com/ETHGlobal​ Website: https://ethglobal.com YouTube: https://www.youtube.com/c/ETHGlobal _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _Are you interested in Ethereum development and entrepreneurship?_ 👉 Sign up for the next ETHGlobal event: https://ethglobal.com/events 🎁 Get exclusive access and perks with ETHGlobal Plus! https://ethglobal.com/plus 📣 Want us to throw an event in your city?

E.G. Galano

ETHGlobal · May 9, 2026

In this talk, E.G. Galano, co-founder of Infura, draws parallels between the evolution of blockchain infrastructure and today's AI infrastructure to share lessons on product differentiation in the agentic era. He traces Infura's journey from being the first Ethereum RPC gateway in 2016, through scaling challenges during CryptoKitties and DeFi Summer, to eventually losing market share as infrastructure commoditized — and how they responded by moving up the stack into multi-chain support, NFT APIs, and higher-margin indexing services. E.G. argues that AI inference is following the same pattern: starting as base-layer access, adding abstractions, then requiring coordination and outcomes layers. He shares his personal "E-Stack" project — a multi-agent system mirroring Infura's org chart with agents for protocol upgrades, SRE, support, product management, and even a crypto Twitter lurker for incident detection. He then presents Infura's marketplace vision where anyone can permissionlessly serve RPC traffic with staked SLAs and verifiable reputation scores, and explains how this model extends to AI skill and API marketplaces — solving the problem of data-driven, verifiable tool selection for agents that currently rely on Reddit sentiment rather than actual performance metrics. 00:00 Introduction 00:10 Inference Is the New Infrastructure 01:37 Parallels Between Ethereum and AI Infrastructure Cycles 03:09 Abstractions: From RPC to Specialized AI Models 03:53 Scaling Challenges and Battle-Testing 04:40 What Is Infura and Its Core Value Proposition 05:58 CryptoKitties, ICOs, and DeFi Summer Scaling 07:19 Self-Hosting vs Managed Services: The Recurring Debate 08:18 Declining Market Share Despite Growing Users 09:52 Differentiating When Infrastructure Commoditizes 10:25 Going Multi-Chain as Costs Decreased 11:27 AI's Next Layer: Outcomes and Agent Coordination 12:49 The E-Stack: A Multi-Agent Infura Org Chart 15:05 Building Moats: Network Effects Over Code 16:41 Infura's Marketplace: Permissionless RPC Providers 17:29 Agent Discovery, Payments, and Reputation 18:28 Verifiable Performance Scoring for Marketplaces 19:12 Extending to AI Skill and API Marketplaces 20:02 Data-Driven Decisions for Vibe-Coded Production Apps 21:04 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *Pragma Cannes 2026* Pragma Cannes 2026 was held on April 2nd at the JW Marriott Hotel in Cannes, France and was an in-person summit for builders and leaders in the web3 ecosystem.

Kevin Jones

ETHGlobal · May 9, 2026

In this workshop, Kevin Jones, a developer relations engineer with seven years in the Ethereum ecosystem, demonstrates building a decentralized auction application using two approaches: hands-on development with Scaffold ETH and AI-assisted coding with OpenClaw. He walks through the full Scaffold ETH workflow — scaffolding a project, deploying a smart contract to a local chain and then to Base, verifying the contract on-chain, and publishing the front end to IPFS and Vercel. The session highlights the practical tradeoffs between manual and AI-driven development, showcasing ETH Skills as a set of guardrails for AI agents building on Ethereum. Kevin also covers Speedrun Ethereum's educational challenges, prompt engineering best practices for tools like Cursor and Claude, and introduces OneClaw, a secrets management tool for AI agents. The live demo candidly reveals both the power and pitfalls of AI coding tools, with OpenClaw crashing mid-demo while the manual Scaffold ETH approach succeeds. 00:00 Introduction 01:35 Workshop Overview: Human vs AI Building 02:23 What Is Scaffold ETH 03:13 Introduction to ETH Skills 04:21 Setting Up OpenClaw with ETH Skills 04:57 Prompting Strategy: Claude to OpenClaw 05:42 Scaffolding a Project with Create ETH 07:05 Project Structure Walkthrough 08:56 Next.js Front End and Scaffold Hooks 11:09 ABI and TypeScript Type Generation 13:01 Checking on OpenClaw Progress 14:06 Running the Local Chain and Deploying 15:24 Scaffold ETH UI and Burner Wallet 17:30 AI Builds the Auction Contract 18:54 AI Mistakes: Foundry vs Hardhat 22:20 Deploying the Auction Contract to Base 25:21 Generating and Funding a Deployer Key 27:25 Verifying the Contract on Base 29:04 Fixing the AI-Generated Front End 30:20 Publishing to IPFS and Vercel 34:53 Speedrun Ethereum Overview 38:45 Synthesis Hackathon and Bonfires 40:27 OpenClaw Status Check 43:33 Q&A: Reverting vs Fixing AI Mistakes 46:08 Live Demo: Creating an Auction on Base 52:04 Q&A: Cursor vs VS Code Workflow 56:30 Q&A: When Not to Use Scaffold ETH 57:33 OneClaw: Secrets Management for AI Agents 1:00:08 Closing Remarks _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *ETHGlobal Cannes 2026* This workshop is specifically for ETHGlobal Cannes 2026, a 3-day hackathon held April 3-5 at the Palace of Festivals and Congresses of Cannes, 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!

ETHGlobal · May 9, 2026

In this workshop, Gathin T from 0G provides a refresher on the 0G stack for hackathon participants and walks through the builder hub. He frames 0G's mission around solving trust vulnerabilities in the agent economy, where centralized AI acts as a black box with no verifiability of inputs, outputs, censorship resistance mechanisms, or actual inferencing costs. 0G addresses this as a Layer 1 EVM-compatible chain purpose-built for on-chain AI with four core components: storage, data availability, compute, and a service marketplace. Gathin T explains key technical updates including the simplified storage SDK with just uploader and downloader functions (no flow contracts needed), recently launched encryption for data uploads, and KV storage achievable through the existing log storage. He covers 0G's verifiable inferencing through TEE environments with ZKML proofs across models like GLM 5.1, DeepSeek 27B, and GPT-OSS, plus on-chain fine-tuning. He dives deeper into ERC-7857 (Agentic IDs), explaining why ERC-721/1155 don't work for AI agents (static metadata, no encrypted model data, no re-keying on transfer) and how the new standard enables encrypted metadata, TEE oracle re-encryption on transfer, and up to 100 delegated users per token. The hackathon offers two $7.5K tracks (framework/tooling and agent builds), and Gathin T introduces the Guild on 0G 2.0 grants program for post-hackathon scaling support. 00:00 Introduction and Workshop Overview 00:58 Speaker Introduction 01:13 The Trust Problem in the Agent Economy 02:13 What Is 0G: Decentralized AI Operating System 02:45 Four Core Pillars Overview 03:29 Why Native Storage for AI Workloads 04:27 Data Availability Layer Explained 04:58 Verifiable Inferencing in TEE Environments 05:30 On-Chain Fine-Tuning and Model Marketplace 06:39 Problems with Centralized AI Today 07:32 Censorship Control and Incentive Structures 08:24 0G Storage SDK: Uploader and Downloader Functions 09:39 How Data Distribution and Merkle Trees Work 10:08 Recently Launched Encryption Feature 10:32 Cost Comparison: AWS S3 vs 0G Storage 11:29 GLM 5.1 and Verifiable Inferencing with ZKML 12:09 DA Throughput, TPS, and Sub-Second Block Finality 12:40 ERC-7857: Why Existing NFT Standards Don't Fit AI 13:34 Agentic ID Features: Re-Encryption and Delegation 13:58 Mainnet Launch and Ecosystem Stats 14:55 Guild on 0G 2.0 Grants Program 15:49 Alignment Nodes and Governance 16:27 Hackathon Tracks: Framework and Agent Builds 17:18 Project Idea Bank and MVP Review Support 17:53 Builder Hub and Telegram Support Channel 18:11 Closing and Office Hours Transition _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🤖 *Open Agents 2026* This workshop is part of Open Agents 2026, an online hackathon held from April 24 to May 6.

Austin Griffith

ETHGlobal · Nov 9, 2025

Austin Griffith continues his Ethereum building series by showing how to deploy a decentralized exchange (DEX) using Scaffold-ETH and the Speedrun Ethereum curriculum. He begins by revisiting the simple counter app from the previous session, deploying it to Arbitrum, and explaining why developers should move beyond testnets to use inexpensive Layer 2s for real deployments. After configuring Scaffold-ETH to point to Arbitrum, he connects a wallet, interacts with the live contract, and emphasizes publishing both the smart contract and frontend to IPFS. Austin then introduces the concept of scaling from simple apps to real-world use cases by following Speedrun Ethereum challenges—covering NFTs, staking systems, token vendors, games, and eventually, DEXs. He walks through the logic behind building decentralized systems where users don’t have to trust intermediaries. Starting with staking and token sales, he explains how incentives and state machines create autonomous coordination among users. The talk culminates with the DEX concept, describing how liquidity pools and constant-product equations (x*y=k) enable trustless token swaps. Liquidity providers earn small fees while users trade freely, and developers act as the “hardware builders” creating these hyperstructures that can’t be censored or shut down.
