In this talk, Elizabeth Peng, COO of Celo Corp (the merged entity of Celo Labs and the Celo Foundation), positions Celo as the number one blockchain for stablecoin payments, built since its Earth Day 2020 launch to create conditions of prosperity for all. She walks through Celo's journey of being EVM compatible L1 to becoming an Ethereum L2 while preserving full network state, and highlights its early differentiators that are now table stakes elsewhere: paying gas with multiple ERC-20 tokens including native USDC and USDT, ultra low gas fees, mobile first design, and multicurrency support. The chain has processed over 1.3 billion transactions, has 600,000 daily active users with verifiable phone numbers, $263 million in TVS, and just hit a peak $6.2 billion in monthly stablecoin trading volume. Liz details Celo's emerging markets product market fit, supporting 25+ stablecoins ranging from US dollar denominations to local currencies like Kenyan shilling, Nigerian Naira, Philippine peso, and Colombian peso. Celo is the number one chain for Tether's USDT with 5 million weekly active users (ahead of Tron's 3 million), and leads tokenized gold with 100,000+ XAUT holders, with over 90% of XAUT's growth coming from Celo. She previews USAT, Tether's new Genius Act compliant stablecoin issued by Anchorage, coming to Celo as the second chain after Ethereum. The Opera Mini Pay partnership has activated 15 million wallets across 60+ countries with 430 million lifetime transactions and 80 million more users coming online to redeem browser points onchain. Liz also covers the Self privacy protocol using biometric IDs and ZK proofs (recently acquired Linum, now led by former Uber AI head Burju Shaw), the Updown perps DEX targeting the $7.5 trillion FX market, and Celo's tokenomics overhaul driving record chain revenue of $18,000 in a single day. She closes with the regional DAO network spanning Latin America, Europe, Arabia, Africa, Thailand, Korea, Philippines, and India that keeps the ecosystem decentralized and accountable. 00:00 Introduction 00:31 Building the Future, Not Just Prototyping It 01:17 What Is Celo 01:38 Celo's Mission and Origins 01:59 Early Innovations: Multi Token Gas, Mobile First, Multicurrency 02:41 Partners: Tether, Circle, Opera 03:01 Network Stats: 1.3 Billion Transactions 03:27 $6.2 Billion in Monthly Stablecoin Volume 03:56 The Vision: Global Venmo for Crypto 04:00 25+ Stablecoins in Local Currencies 04:30 #1 Chain for USDT with 5 Million Weekly Active Users 05:32 Leading Tether Gold and Tokenized Commodities 06:21 USAT Coming to Celo Second After Ethereum 06:53 Mini Pay Gold Use Cases and Cashback 07:14 Opera Mini Pay: 15 Million Activated Wallets 07:59 Regional Road Shows and Opera Partnership Extension 08:49 Updown: Onchain FX Targeting $7.5 Trillion Opportunity 09:23 Self: Privacy Protocol with Biometric ZK Proofs 10:20 Google Cloud Partnership and Boosted Yields 10:49 Self Acquires Linum, Burju Shaw From Uber AI 11:23 Mind Share and Industry Recognition 12:17 Top 5 Chain for Agent Activity on ERC-7804 Registry 12:41 Industry Praise: Vitalik, Bankless, Super Chain 13:06 The L2 Migration Playbook 13:38 Record $18,000 Chain Revenue Day 14:04 Block Space Business Is Alive 14:04 Regional DAO Network Around the World 14:47 Full Ecosystem of 1,000+ Projects in 150+ Countries 15:24 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 · Jul 9, 2026

In this talk, Scott Dykstra from Space and Time explains how his team is building the data layer for Ethereum's institutional era, providing data to smart contracts from institutional portfolios offchain or secured events onchain. Space and Time is a decentralized onchain database that lets smart contracts ask complex questions. When they started in late 2021, they set out to build the first verifiable ZKP-proven SQL database, using zero knowledge cryptographic proofs for queries asked by smart contracts. The original insight was that a lending smart contract knows nothing about the borrower wallet transacting with it (DeFi protocols have no database to query and aggregate past activity), so Space and Time brings an onchain database that lets contracts roll up and aggregate the history of wallet transactions and events, proven back to the contract by the next block. He frames this as the next step beyond the price-feed oracles that enabled DeFi summer in 2020: letting a smart contract actually run a SQL query aggregation, a powerful primitive for institutions entering lending and vaults. Scott describes the technology as a blockchain sitting next to the EVM that lets you create tables, insert data, and run SQL queries, paying a few SXT tokens per action (for example, creating a T-bill volumes table and querying it from a contract to mint stablecoins backed by offchain T-bills). With the Clarity Act about to pass, he sees fintechs like Stripe, PayPal, and Circle having shown banks how to mint stablecoins backed by reserves, and now major banks hiring contractors to tokenize offchain securities. The real unlock is programmable finance: banks can codify rules around minting, volume thresholds, and marking to market, extending beyond stablecoins to CLOs, equities, and commercial real estate repriced as often as desired. Space and Time acts as the secure conduit that reaches into locked-down offchain portfolios and ZK-proves to a contract that aggregated data (say, total collateral across 17 portfolios on two clouds) is accurate and untampered, ensuring minted stablecoins always match reserves in near real time. He extends this to virtual vaults that give lenders a data room and dashboard showing borrower collateral and deployed capital across exchanges and DEXes, then lets the vault contract itself run SQL queries to enforce thresholds and margin calls, enabling compliant, largely uncollateralized lending. He closes on DeFi itself, where querying a wallet's history of repaid loans could earn experienced borrowers better rates, powering a new wave of onchain lending. 00:00 Introduction 00:33 Building the Data Layer for Ethereum 00:58 The First Verifiable ZK-Proven SQL Database 01:33 Why Smart Contracts Have No Database 01:58 A Verifiable Pipeline of Data to Smart Contracts 02:19 Beyond Price Feed Oracles 02:38 How the Technology Works 02:52 Spending SXT to Create, Insert, and Query 03:15 Why Banks Are Leaning In 03:38 From Fintechs to Major Banks 03:56 The Benefit of Programmable Finance 04:44 Codifying Business Logic On Chain 05:16 Where Traditional Securities Data Lives 05:42 The Need for a Secure Conduit 06:12 ZK Proving Data From Offchain Portfolios 06:50 Why This Is More Than an Oracle 07:13 Aggregating Across 17 Portfolios 07:52 Why It Must Be Near Real Time 08:25 Extending Beyond Stablecoins 08:52 Why SQL Is a Familiar Primitive 09:15 Why You Cannot Aggregate Without This 09:48 The Problem of No Asset Provenance 10:39 Taking It Further Into Vaults 11:17 Why Banks Need Borrower Transparency 11:42 The Opaque World of Ethereum Vaults 12:26 Introducing Virtual Vaults 12:57 Giving Lenders a View of Borrower Capital 13:39 The Investor Dashboard and Data Room 13:56 Feeding Data to the Vault Contract Itself 14:22 Codifying Margin Calls and Business Rules 14:53 An End-to-End Example 15:55 Smarter Vaults Beyond Morpho 16:30 What About DeFi Itself 17:03 Rewarding Loyal Borrowers With Better Rates 17:29 The Year Ahead for Banks and DeFi 17:48 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.

Shady El Damaty

Funding the Commons · May 9, 2026

As AI agents increasingly mediate human interaction, how do we make sure people stay in control of their own digital lives? Shady, co-founder of Holonym Foundation and the team behind human.tech, comes from computational neuroscience and applied cryptography. He argues that the current trajectory of AI development pulls resources, talent, and capital into a one-way infrastructure that gives little back — and that cryptographic tools, specifically zero-knowledge proofs, offer one of the most underused levers we have to redistribute power back to individuals. The core question he poses: what is the most important thing you could be building right now, with everything you have at your disposal? For Shady, the answer is technology that proves you are human, without giving up what makes you so. Speaker: Shady El Damaty (Holonym Foundation / human.tech) This session was part of Intelligence at the Frontier, held March 14–15, 2026, at Frontier Tower in San Francisco.

Josef Je

ETHGlobal · May 9, 2026

In this talk, Josef Je introduces the European Ethereum Institute, a newly launched task force dedicated to getting Ethereum recognized as strategic public infrastructure by European regulators — comparable to the internet or the electric grid. He argues that after a decade of builders ignoring policy, regulation has now caught up to the point where DeFi, tokenization, and MEV are being discussed in EU papers, and the community must engage proactively or risk being overshadowed by permissioned chain salespeople pitching proprietary tech to uninformed regulators. Josef frames the urgency through Europe's risk of repeating the Web2 pattern where all innovation and business creation migrated to Silicon Valley while the EU could only react through after-the-fact regulation. He outlines the institute's three-pronged approach: producing evidence-based papers and infographics showing regulators the differences between true DeFi and centralized projects, helping regulators understand the full Ethereum technology stack beyond finance (identity, voting, ZK proofs, timestamping), and proactive outreach to bring regulators into crypto events. He announces that André Kvapiš, a former European Parliament member who helped remove DeFi from MiCA's scope, has officially joined the institute, and shares that initial funding comes from Ethereum Foundation, Aave, and Gnosis. 00:00 Introduction 00:29 Why a Builder Started Caring About Policy 02:09 Institutions Coming On-Chain: Now or Never 03:42 Launch of the European Ethereum Institute 04:22 Permissioned Chains Are Back (and Still Wrong) 05:10 Ethereum as the Golden Standard 06:05 "It's Ethereum, Not Blockchains" 07:00 Ethereum's Lindy and Network Effects 07:31 Mission: Ethereum as Strategic Public Infrastructure 08:55 Europe's Risk of Repeating the Web2 Mistake 10:14 Providing Evidence to Regulators 11:39 Tokenization, Stablecoins, and True DeFi 13:10 Ethereum's Stack Beyond Finance: Identity, Voting, ZK 14:22 A Task Force, Not Another Association 15:58 How a Regulator Joined the Ethereum Side 17:11 André Kvapiš and MiCA's DeFi Exemption 18:37 Team, Funding, and How to Get Involved 19:56 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.

Rene Reinsberg

ETHGlobal · May 9, 2026

In this talk, Rene Reinsberg, founder of Celo and Self, presents how Self is bootstrapping global-scale proof of human infrastructure using zero-knowledge cryptography and government-issued identity documents. He announces a partnership with Google and Tether where users can verify their unique humanity through Self, claim free stablecoins, and send them to their wallet — launching next month. The system works by NFC-scanning passports or national IDs, cryptographically verifying document authenticity through country signing certificate authorities, and generating zero-knowledge proofs without storing any user data. Rene explains how applications can then request disclosure proofs (age verification, country of origin, OFAC screening) without handling PII, making it preferable to traditional KYC. He connects this to the agentic world, citing examples like Moldbook (an agent social network acquired by Meta) and Rent a Human marketplace, arguing that proof of human becomes critical when agents need to verify human counterparties or delegate identity without exposing personal data. The system enables agents to hit verification barriers in workflows and trigger ZK proof requests back to the human, unblocking agentic commerce without sharing actual identity data with the AI. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 00:00 Introduction 00:10 Welcome and Context: From Celo to Self 00:57 Why Proof of Human Matters Now 02:32 Google and Tether Partnership Announcement 03:55 Google's Use of Self for Testnet Faucets 05:29 Vision: Social Services and UBI on Crypto Rails 06:31 Why Proof of Human Is Becoming Urgent 07:41 Government Identity Infrastructure as a Foundation 09:01 How Self Works: NFC Scanning and ZK Proofs 10:43 Why NFC Beats Traditional KYC in an AI World 11:43 Zero Knowledge: No Data Storage, No Trust Required 12:13 Disclosure Proofs: Age, Country, Sanctions Screening 13:56 Registration and SDK Integration 14:20 Proof of Human in the Agentic World 15:04 Moldbook and Agent Sybil Attacks 16:00 Rent a Human: Agents Hiring Verified Humans 17:14 Delegating Identity to Agents Without Sharing Data 18:36 Self for AI Agents: Unblocking Agentic Workflows 19:44 Resources: self.xyz and ai.self.xyz 20:09 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.

ETHGlobal · May 9, 2026

In this workshop, Mateo Sauton from TFH (the labs that build for World) introduces World ID, MiniKit, and Agent Kit for the Open Agents hackathon. He frames the urgency of proof of human verification: with up to 75% of internet traffic now being bots and CAPTCHAs no longer effective against advanced AI agents, World ID provides a privacy-preserving way to prove uniqueness and humanity online using ZK proofs. The system has three verification levels — device, document (NFC ID/passport), and orb (the highest, fully unique human verification). Mateo walks through World's three product surfaces: ID Kit for integrating proof of human into any web or mobile app (with backend proof verification required for the hackathon), Mini Apps that inherit World App's massive distribution of nearly 40M users and 7.5M monthly actives, and the newly released Agent Kit which lets users delegate their World ID to AI agents. He covers the core MiniKit commands (verify, pay, sign-in with Ethereum, send transaction, notifications, world chat), shares case studies including Ouro's daily airdrops to 175K+ humans, Credit's uncollateralized loans to 1M+ verified users, Morpho's boosted APY vaults, and a 21-day fitness staking app. The hackathon offers a $20K prize pool split across three tracks: best use of Agent Kit, best use of World ID, and best use of Mini Apps. 00:00 Introduction 00:38 The Agentic Economy and Why World Matters 01:55 What World ID Solves: Proof of Human 02:47 Privacy-Preserving Verification with ZK Proofs 04:14 Why Uniqueness Unlocks New Use Cases 04:52 Integrating ID Kit on Phone and Desktop 06:11 Developer Portal and SDK Setup 06:42 Backend Proof Verification Requirement 07:46 On-Chain vs Cloud Verification 08:24 Mini Apps: Inheriting World App's Distribution 09:15 The Verify Command and Three Verification Levels 11:10 The Pay Command for Gasless Transactions 11:58 Sign-In with Ethereum and Cross-Platform Sessions 12:42 Send Transaction and Permits 13:35 Notifications and World Chat Integration 13:55 Mini Apps Ecosystem Stats: 2.1B Opens 14:50 World App User Base: 38M Total, 18M Verified 15:43 Mini Apps Ecosystem Growth 16:09 Introducing Agent Kit: Delegating World ID to Agents 17:32 Use Cases: Ticketing and Rate Limiting for Agents 18:22 Case Study: Ouro Daily Airdrops 19:16 Case Study: Credit Uncollateralized Loans 20:55 Case Study: Morpho Boosted Yields 21:23 Case Study: WLD Fitness Staking App 22:04 Three Hackathon Tracks: $20K Prize Pool _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *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!

EthCC · Aug 8, 2024

Hashi and SafeJunction are permissionless abstraction layers to create secure and future proof dapps. Hashi was designed to avoid bridging lock-ins and to enable higher degrees of security. SafeJunction extends this concept beyond cross-chain bridging, to verifiable arbitrary computations. The video discusses the importance of security in-depth for off-chain computations, particularly in the context of blockchain scalability and the use of proofs. The speaker explains how layer 2 and layer 3 solutions inherit security from Ethereum's base layer through proofs, which are essential for various applications like scalability, interoperability between layers, and external data verification through oracles. The concept of a "proof layer" is introduced as an abstract idea that is critical for blockchain security but does not yet exist in a concrete form. The speaker then delves into three main use cases for proofs: improving scalability through vertical integration of layers, decomposability across different systems, and co-processing to offload heavy computations while maintaining transparency and privacy. They also discuss the potential future where everything in the blockchain ecosystem operates via proofs, with layer 1 blockchains primarily verifying these proofs. However, there are challenges today in achieving this vision due to inefficiencies, fragmentation, trust assumptions, and high costs associated with proof generation and verification. Additionally, there are concerns about large attack surfaces and dependencies on unreliable code libraries. To address these problems, the speaker suggests design principles such as avoiding vendor lock-ins, implementing security in depth by using multiple layers of protection, and designing systems that are future-proof to withstand potential risks over
