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!

ETHGlobal · Jul 9, 2026

In this talk, Rodrigo Coelho, CEO of Edge & Node, explains why banks are racing onchain in 2026, covering what is working in production today and what is not, and what infrastructure moving production financial workloads on chain actually requires. He opens on how most of the world's money still moves on software written in the 1970s, likening institutions going on chain to a dial-up to broadband moment, or streaming music forced through record players. In 2026 the pilots of past years are moving into production: the New York Stock Exchange is working on 24/7 tokenized trading and tokenized assets are becoming collateral, all converging because the regulatory clock is ticking with the Genius Act, Clarity Act, and MiCA turning compliance frameworks from white papers into laws. Having spent eight years shipping blockchain infrastructure (from the first commit at The Graph to running Edge & Node, serving 1.8 trillion queries), Rodrigo says the Genius Act taking effect January 27th is a forcing function, and given long procurement cycles, institutions that wait for tooling will miss the window. Rodrigo argues banks are bringing the wrong assumptions on chain: their data stacks assume finality, append-only ledgers, overnight batch windows, and ACH and wire transfers, treating reorgs as edge cases when reorgs are normal, and off-the-shelf warehouses like Snowflake, Postgres, and BigQuery do not work out of the box with on-chain data, which is rarely cryptographically verifiable. Using the wrong tools breaks data freshness, auditability, and verifiability, and bad data puts capital at risk through stale collateral, blown liquidations, and compliance violations, with 24/7 markets that never pause. He lays out five non-negotiables for institutional data infrastructure: sub-second data freshness (block to query in under a second), verifiable cryptographic lineage, multi-chain access (The Graph indexes over 90 chains), on-prem deployment for data sovereignty in jurisdictions like the Middle East, Brazil, and Japan, and SQL-native querying that engineers and AI both speak. He gives vendor-evaluation questions and introduces Amp, Edge & Node's SQL-native, on-prem-capable blockchain data platform with verifiable extraction and full lineage across 100 chains that bridges into existing stacks. He shares production numbers (747 millisecond freshness, 100x pipeline improvement, 4,350x faster backfills), contrasts pay-per-query versus flat-fee licensing, and closes that the institutions moving now will own the next decade of financial infrastructure. 00:00 Introduction 00:41 Money Still Runs on 1970s Software 01:05 Why 2026 Is When Pilots Go to Production 01:35 Why the Regulatory Clock Is Ticking 01:57 Rodrigo's Background at The Graph 02:16 Why Now: Genius Act, MiCA, and Global Momentum 02:44 Why Waiting for Tooling Misses the Window 03:13 The Genius Act as a Forcing Function 03:42 What Institutional Conversations Revealed 04:11 Banks Bringing the Wrong Assumptions On Chain 04:34 Why Reorgs Break TradFi Assumptions 04:56 Why Off-the-Shelf Warehouses Fail 05:28 Why On-Chain Data Is Rarely Verifiable 05:40 The Three Things That Fail 06:01 Why Bad Data Puts Capital at Risk 06:33 Why 24/7 Markets Reward First Movers 06:56 The Five Non-Negotiables for Data 07:23 Multi-Chain Access and On-Prem Deployment 07:47 Why SQL Native Is a Requirement 08:07 Questions to Ask Every Vendor 08:30 Red Flags in Data Vendors 08:57 Introducing Amp 09:21 Joining On-Chain and Off-Chain Data 10:30 Amp's Production Numbers 11:00 Pay Per Query vs Licensing the Platform 11:50 How Compliance Becomes Provable 12:18 Why Amp Was Built for Tokenized Deposits 12:41 What Rodrigo Tells Every Institutional CTO 13:36 Why the Future of Finance Is Multi-Chain 14:13 Why Infrastructure Choices Decide the Leaders 14:39 The Rise of Heads of Digital Assets 15:02 Consulting to Navigate the Vendor Landscape 15:29 Building the New Way Money Moves 16:07 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.

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.

Kartik Talwar

ETHGlobal · May 9, 2026

In this fireside chat, Kartik Talwar interviews Andrej Bencic, founder of Tenderly, about the evolution of Ethereum developer tools over the past eight years and how AI is reshaping smart contract development. Andrej describes how the multi-chain world has fundamentally changed development — teams now need to test across multiple forked mainnets with bridges, manage indexing across chains, and handle inconsistencies when chains go down. He contrasts today's production-grade stack (Foundry, account abstraction, staging environments) with the 2018 era of Truffle and Ganache. The conversation explores three distinct developer personas Tenderly serves: newcomers focused on smart contract integration and DeFi composability, OG teams like Aave pushing protocol frontiers, and institutional players held back by risk aversion. Andrej details how Tenderly's simulation technology helps manage operational risk post-deployment — from transaction simulation in Gnosis Safe to treasury management. He highlights their MCP integration that gives AI agents a sandboxed fork of mainnet to debug transactions (processing 50MB of data per transaction) and test workflows in a parallel universe before committing to production, calling it a critical safety net against the inevitability of AI-driven development. 00:00 Introduction 00:10 What Is Tenderly and Eight Years of Developer Tooling 01:43 How Multi-Chain Development Has Changed Everything 04:09 Cross-Chain Testing: Forking Multiple Mainnets 05:08 The Modern Developer Stack vs 2018 06:45 Production-Grade Development: CI/CD and Staging 08:17 AI Skills and Delegating Ethereum Context 09:04 Three Developer Personas: Newcomers, OGs, and Institutions 11:36 Institutional Risk Aversion as the Main Bottleneck 12:40 Managing Operational Risk Post-Deployment 14:16 Transaction Simulation and Avoiding Blind Signing 15:12 AI Agents and Smart Contract Development 16:02 Sandboxed Fork Environments for AI Workflows 17:33 Tenderly's MCP: Debugging and Testing for AI 18:40 AI Processes 50MB of Transaction Data Better Than Humans 19:22 Advice for New Smart Contract Developers 21:25 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 · Nov 9, 2025

Kevin Jones from Edge & Node introduces The Graph as a decentralized indexing layer for blockchain data, emphasizing its evolution beyond subgraphs to include token APIs, MCP servers, Substreams, and Hypergraph. For the hackathon, developers are encouraged to build with these newer tools to qualify for bounties. He explains how Substreams enables real-time blockchain data streaming to external databases, while Hypergraph allows developers to build knowledge graph-based applications with private, encrypted, and verifiable data. The platform integrates Geo Connect for authentication, uses React with Next.js or Vite for front-end scaffolding, and introduces GRC20, the specification for structuring and publishing data to the decentralized knowledge layer called Geo. The demo walks through how developers can create public and private spaces, manage entities, and publish encrypted or public data using the Hypergraph framework. Kevin highlights the role of TypeSync, a tool that visually manages schema types and relationships within projects, and demonstrates the end-to-end process of authenticating, creating entities, syncing schemas, and publishing data. Example applications include DApp registries, governance platforms, and collaborative tools where users can maintain both private and public datasets. Ultimately, Hypergraph provides a full-stack, privacy-first framework for decentralized knowledge sharing, opening new pathways for structured, reusable, and encrypted blockchain data. 00:02 – Introduction & Overview of The Graph 00:47 – Decentralized Indexing & Data Access 01:12 – Token APIs, MCP Servers, and Substreams 02:16 – Hackathon Bounties & Categories 02:39 – Introduction to Hypergraph Framework 04:06 – Private Data & Local-First Encryption 05:16 – Full-Stack Setup with React, Vite, and Next.js 05:44 – Knowledge Graphs Explained (Entities, Relations, Spaces) 07:10 – Public vs Private Spaces in Hypergraph 08:02 – Sync Server & Geo Connect Architecture 08:55 – Code Example: Entities and Relations 10:19 – Publishing to Knowledge Graph (Public/Private Data) 10:40 – Example Use Cases: Crypto Projects, Governance, Registries 11:23 – Demo: Setting Up a Hypergraph Project 12:10 – Scaffolding with NPX & Framework Options 13:16 – Using TypeSync for Schema Management 15:16 – Creating Private & Public Spaces 17:29 – Exploring Knowledge Graph Data 18:05 – Managing Schema and Types in Code 19:43 – Updating and Syncing Entities 20:04 – Publishing Data to Sync Server and Knowledge Graph _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *ETHGlobal New Delhi* This workshop is specifically for ETHGlobal New Delhi, a 3-day hackathon held September 19-21 at the India International Convention & Expo Centre, 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!

Swarm · Jun 21, 2024

A concept on how to create a search index for NFTs that can be served from Swarm. The video is about exploring advanced search capabilities for NFTs and potentially other data types using decentralized indexing. The speaker introduces a proof of concept that aims to provide better search experiences by indexing NFTs in a decentralized manner, similar to how Google indexes web pages. The process involves fetching NFT images and metadata, processing them with AI models to extract descriptive keywords, and building an index for efficient searching. The demo uses OpenSea's API, AI frameworks like Lankchain and Olama, and specific AI models for image recognition and keyword extraction. The resulting index can be stored on Swarm, ensuring it's censorship-resistant and globally accessible. Applications include enhancing NFT marketplaces, creating new standards for searchable NFTs, DeFi analytics, identifying fraudulent NFTs, and boosting the adoption of Swarm. The talk also touches on potential future developments like enabling Swarm nodes to perform AI computations. Questions from the audience address the uniqueness of this approach compared to existing traits-based searches on platforms like OpenSea and the updatable nature of the index.
