ETHGlobal · Jul 9, 2026

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.

Yoseph Ayele

ETHGlobal · Jul 9, 2026

In this talk, Yoseph Ayele from LAVA presents a ground level view of how stablecoins actually function in African markets, challenging the assumption that the continent is too small, too risky, or too distant to matter for global stablecoin adoption. He frames Africa as an early signal for what's coming everywhere, with stablecoins already embedded into how money moves, how finance operates, and how value gets created. The fundamental insight is that while Western stablecoin builders are trying to take market share from traditional finance, African builders are filling gaps banks left entirely, which creates fundamentally different building pace and defensible moats. Yoseph walks through real use cases that go beyond the dominant remittance and software developer payment narratives. Trade finance is the deepest volume, where businesses importing and exporting everything from t-shirts to oil and gas need to move money fast. He notes that African banks lend to governments and large corporations representing only 10% of the economy, leaving the other 90% (SMEs and mid market players) without bank credit while still asking them to use the same banks to move money across borders. This traps cash flow and exposes businesses to FX risk on volatile currencies, while stablecoins offer instant settlement at a fraction of the cost. He covers unified treasury management replacing the fragmented multi currency float requirement, and FX market coordination where stablecoins aggregate liquidity onchain so someone with $1 and someone with $1 billion can participate in the same market. He breaks down three prices for the Nigerian Naira: the central bank's "wish price," banks' "do you qualify price" with premiums for license preservation, and the open market stablecoin price, with margins ranging from 2 to 25% in Nigeria and up to 120% in his native Ethiopia. He closes by previewing how onchain FX options markets for local currency stablecoins enable transparent risk pricing, arguing that emerging markets are building both TradFi rails and fully onchain permissionless marketplaces in parallel, with everything ultimately moving toward open onchain economic structures. 00:00 Introduction 00:11 Show of Hands: Stablecoin Cross Border Payments 00:40 Why Africa Matters Despite Being a Flyover Region 01:10 Africa as an Early Signal for Global Adoption 02:20 Western Builders Take Share, African Builders Fill Gaps 03:05 Use Case: Trade Finance Is the Deepest Volume 03:51 Banks Only Lend to 10% of the Economy 04:20 How Banks Trap Cash Flow With Float 04:37 Stablecoins as Instant Settlement at Lower Cost 05:30 Use Case: Unified Treasury Management 06:20 Use Case: FX Market Coordination 06:42 Aggregating Liquidity From $1 to $1 Billion 07:19 Why Shell and Chevron Already Use Stablecoin Rails 07:43 How Money Actually Flows: The Flow Diagram 08:58 Settlement Times: Minutes to 24 Hours 09:26 Crypto Thriving Despite Regulation, Not Because of It 09:46 The Three Naira Prices 10:10 The Wish Price From the Central Bank 10:35 The Do You Qualify Price From Regulated Banks 10:35 The Open Market Stablecoin Price 11:06 Margins From 2% to 120% in Ethiopia 11:28 Speed of Execution as the Real Variable 11:52 Good Governance Follows Good Markets 12:36 Price Discovery for Local Currency Oracles 13:02 Pricing FX Risk a Year Out 13:44 Onchain Options Markets for Local Currency 14:16 Why Transparent Pricing Unlocks Capital 14:38 Building TradFi Rails and Onchain Markets in Parallel 15:21 Closing: Toward Fully Onchain Permissionless Marketplaces _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *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 more technical talk, Greg Swirski from Reilabs explains how his team solved the Keccak bottleneck in zero knowledge SNARKs. He opens by grounding zero knowledge cryptography, often called the future of Ethereum and blockchain scaling, in three concrete uses. First, increasing transaction volume: today every Ethereum node must re-execute transactions to check they followed the rules, which caps throughput, but if validators only need to verify a proof rather than re-execute, the whole network can scale. Second, onboarding institutions safely through ZK-KYC, where you never upload passport data to a public chain but instead attest that you are not from a sanctioned country or are an accredited investor via a small proof revealing nothing else. Third, as volume and counterparties grow, private credit or risk scoring lets a party prove they have funds somewhere without revealing positions or strategies. The roadblock across all three is Keccak, the hash function Ethereum and every EVM chain uses to commit to blockchain state, which is fast on CPU but extremely expensive to prove inside ZK circuits, and far too entrenched to replace. Greg's key insight is that you almost never prove a single Keccak hash, always hundreds or thousands at once, and his team leveraged that to beat the state of the art. He shows why: modern ZKVMs spend around 40% of their time proving hidden Keccak hashes you never see in Solidity, storage proofs chain from block hash through state root to account to storage slot, and ZK-KYC wraps a fast but large STARK inner proof inside a tiny SNARK outer proof that must itself compute thousands of hashes. Whereas many use the ZK-friendly but CPU-slow Poseidon hash, their protocol Keccacheck lets you switch back to Keccak (about 10x faster than Poseidon on CPU) for roughly a 5x inner-proof improvement at small outer overhead. The approach builds on the GKR protocol, which expresses programs as polynomials and scales sublinearly (analogous to a GPU versus a CPU), but base GKR was too slow, so they custom-built every Keccak operation to run batch-wise across all instances at once. The result breaks even against a popular state of the art framework at roughly 16 to 32 Keccak instances and runs 10 to 30x faster at 200 to 500 instances. He closes on future applications like mobile proving where passport data never leaves your phone and privacy-preserving institutional ZK-KYC with on-chain agents, pointing to a blog post, white paper, and GitHub repo via QR code. 00:00 Introduction 00:11 A More Technical Talk 00:34 Who Works With ZK Circuits 00:55 Three Aspects of Zero Knowledge 01:03 Increasing Transaction Volume 01:25 From Re-Executing to Verifying Proofs 01:48 Onboarding Institutions With ZK-KYC 02:10 Attesting Without Revealing Passport Data 02:45 Private Credit and Risk Scoring 03:06 The Roadblock: Keccak 03:31 How Keccak Commits to State 03:56 Why Keccak Is Hard to Prove in ZK 04:18 Why We Cannot Just Replace It 04:43 The Key Insight: Proving Many Hashes at Once 05:07 Why We Always Deal With Many Instances 05:30 The Hidden Keccaks in Every Transaction 06:13 Proving Wallet Properties for Risk Scoring 06:33 Chaining Trust From Balance to Block Hash 07:00 The ZK-KYC Problem 07:27 Wrapping a STARK in a SNARK 08:11 Why the Outer Layer Needs Thousands of Hashes 08:35 The Hash Function Trade-Off 08:58 Poseidon vs Keccak 09:21 Introducing the Keccacheck Protocol 09:52 Building on the GKR Protocol 10:20 GKR and Sublinear Scaling 10:49 The CPU vs GPU Analogy 11:13 Applying GKR to Keccak 11:45 Why Base GKR Was Too Slow 12:17 Applying Operations Batch-Wise at Once 12:44 Breaking Even at 16 to 32 Instances 13:19 10 to 30x Faster at Scale 13:45 Still Room to Improve ZK Circuits 14:00 Accelerating Mobile Proving 14:19 Privacy-Preserving Institutional ZK-KYC 14:50 Where to Learn More 15:11 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.

Stani Kulechov, Kartik Talwar

ETHGlobal · May 9, 2026

In this fireside chat, Kartik Talwar interviews Stani Kulechov, founder and CEO of Aave, about the vision behind Aave V4 and the future of DeFi as infrastructure for global credit. Stani explains that V4 introduces a modular hub-and-spoke architecture where liquidity is stored in central hubs that allocate credit lines to customizable spokes — enabling anyone to build new lending models (native Bitcoin collateral, debt trading, fixed lending) while tapping into Aave's existing liquidity pool rather than bootstrapping from scratch. Stani outlines three waves of new collateral entering DeFi: tokenized real-world assets, yield-bearing stablecoins, and data-backed credit facilities for consumers, businesses, and institutions. He discusses the Aave App's fintech-like mobile experience that fully abstracts away wallets, gas, and networks, and reflects on why Ethereum remains the strongest chain for DeFi due to tooling, security community, and liquidity network effects. Looking ahead, he frames the institutional transition as a decade-long journey of replacing financial backend infrastructure dating back to the 1970s, with DeFi serving as the efficient capital allocation layer for all future credit. 00:00 Introduction 00:10 Welcome and Aave V4 Context 00:40 Why V4 Took Two Years to Build 02:10 DeFi as a Backbone for All Future Credit 03:43 V4 Architecture: Hub-and-Spoke Model 04:48 Custom Spokes: Bitcoin Collateral, Debt Trading, Fixed Lending 05:59 Unified Liquidity Access for New DeFi Projects 07:31 New Collateral Types: RWAs, Yield Stablecoins, and Data 08:32 Risk Premiums and Collateral-Based Pricing 09:45 Institutional Requirements and Permissionless Infrastructure 11:11 BlackRock on Ethereum: A Turning Point 12:04 Aave App: Fintech-Like Mobile DeFi Experience 13:35 Building DeFi for Everyone 14:19 Staying Motivated Through Market Cycles 15:35 Why Now Is the Best Time to Build 16:57 Why DeFi Stays on Ethereum 18:36 Five-Year Prediction: A Decade-Long Institutional Transition 20:41 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 · Apr 9, 2026

In this workshop, Matthew Foyle, DevRel lead at Dynamic and Fireblocks, gives a brief overview of Dynamic's wallet infrastructure for ETH Global Cannes builders. Dynamic provides a complete wallet stack available through SDKs and a low-level API, offering Fireblocks-grade security, sub-second signing, and fast implementation for both human users and AI agents. He emphasizes using the SDKs directly rather than pre-built React UIs, and highlights the three-step setup: create an account, grab an environment ID, and install the documentation MCP for AI-assisted development. Matt breaks down the three hackathon prizes totaling $5,000, all judged on "comprehensive use" — a combination of breadth and depth of SDK integration across mobile SDKs (Kotlin, Swift, Flutter, React Native), the JavaScript SDK (framework-agnostic vanilla JS), or the Node SDK. He walks through the quick start flows for each SDK, including an agent-friendly path that lets Claude or Cursor guide configuration decisions. Inspiration categories include digital asset flows, trading flows, cross-border flows, and agentic flows. 00:00 Introduction 00:11 What Is Dynamic 00:52 SDK and API Overview 01:13 Key Features: Fireblocks Security and Fast Signing 01:38 Three Steps to Get Started 02:01 Meet the Team at the Venue 02:24 Hackathon Prizes Overview 02:44 What Is Comprehensive Use 03:55 Use Case Inspiration 04:45 JavaScript SDK Quick Start 05:31 Agent-Friendly Setup Path 06:07 Node SDK Quick Start 06:32 Mobile SDK Example Apps 06:55 Summary and Resources 07:23 Install the Documentation MCP 07:49 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!

Moven Tsai

ETHGlobal · Nov 9, 2025

Moven Tsai (Ethereum Foundation) walks through Morro, a toolkit for building mobile ZK apps that run directly on iOS and Android (including Flutter and React Native). Morro wraps Rust code, exports mobile bindings, and integrates with popular proving stacks—Circom, Halo2, Noir, and RISC Zero—so developers can compile circuits once, generate bindings, and execute proofs and verification on phones. The CLI flow is simple: morro init to scaffold a Rust workspace, morro build to generate iOS or Kotlin bindings for the chosen architectures, and morro create to scaffold mobile app templates. For non-Rust developers, Morro also ships native SDKs (Swift, Kotlin, Dart) and cross-platform templates, plus WalletConnect-enabled verifier demos for onchain flows. Tsai showcases ready-to-fork templates and real app ideas: proof of geolocation, Semaphore-based membership proofs, Aadhaar integrations, JWT domain proofs, and a RISC Zero template that proves ECDSA on device (noting mobile proofs are slower, roughly 90–120 seconds). He highlights patterns for exporting arbitrary Rust functions to mobile via uniffi macros, hot-rebuilding circuits and bindings, and updating app integrations with morro update. The talk closes with hackathon tracks and ideas, including credential sharing from signed PDFs (with zkPDF), unified ZK identity registries with revocation, NFC tap-to-proof UX, mobile-native sensors like GPS and camera, and ZK TEE or MPC-based TEE-on-mobile explorations. 00:00 – Why ZK on mobile matters 01:07 – What Morro is: Rust wrapper, ZK integrations, mobile bindings 01:27 – Supported stacks: Circom, Halo2, Noir, RISC Zero 02:13 – Platform support: iOS, Android, Flutter, React Native 02:37 – Morro CLI overview and recent refactor 03:53 – Install options: main branch vs legacy stable 05:03 – Core workflow: init, build, create templates 05:29 – Building bindings per architecture and simulator vs device 05:51 – Scaffolding iOS, Android, Flutter, React Native apps 06:16 – Circom integration: artifacts, setup, verify on device 06:51 – Exporting arbitrary Rust logic with uniffi 07:52 – Rebuilding circuits and hot updating bindings 08:21 – Use cases and templates tour 08:55 – JWT domain proofs on mobile 09:17 – Semaphore membership: private check-ins (Zuma) 10:03 – Aadhaar integrations and QR scanning, photos 10:30 – Geolocation proofs and GPS ideas 10:53 – Onchain verification templates with WalletConnect 11:27 – RISC Zero on phone: feasibility and timings 12:25 – Example projects: face match in Secure Enclave, ECDSA proofs 13:47 – Wearables and access control demos 14:14 – Additional zk stacks and open-source references 14:37 – Hackathon prize tracks with zkPDF 14:58 – App ideas: credentials, games, matching, NFC tap-to-proof 15:53 – Infra ideas: unified ZK registry and revocation 16:27 – NFC and native sensor exploration 17:00 – ZK TEE or MPC notarization on mobile 17:58 – Resources: slides, GitHub, Telegram, help _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *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!
