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, 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.

Running an Ethereum Node in Africa The video features a security researcher named David who is involved with an initiative supported by the Ethereum Foundation to operate Ethereum nodes in Africa. He begins by explaining what a node is—a software downloaded onto a computer that participates in the Ethereum network. David emphasizes the importance of open source in the blockchain space, contrasting it with traditional banking apps where users must trust the service without being able to verify its code. He then explains that running an Ethereum node involves having certain hardware and software online 24/7, and that anyone can run a node, contributing to the network's decentralization. David notes that less than 1% of Ethereum nodes are currently run in Africa, highlighting the need for greater geographic diversity among node operators to strengthen network security and resilience. David provides details on the infrastructure requirements for running an Ethereum node, including RAM, SSD storage, internet speed, and power supply. He also shows a custom-built node as an example of how one can be assembled with these components. The talk goes on to discuss two types of software needed for nodes: execution clients and consensus clients. Execution clients execute transactions, while consensus clients help produce blocks on the blockchain. David highlights privacy and decentralization as key reasons to run a node. He addresses common misconceptions about the costliness of running a

Ethereum Governance. Speaker: Tim Beiko The video features a live discussion with a key figure in the blockchain space, focusing on the Ethereum community and its governance. The speaker, Tim, has a background in core developer coordination and has contributed significantly to the Ethereum ecosystem. He explains how Ethereum governance works, detailing the roles of different stakeholders such as core developers, EIP champions, consensus participants, node operators, users, and the broader community. Tim emphasizes the importance of protocol rules and specifications that nodes must implement to maintain network integrity. He also discusses contentious forks in Ethereum's history and how governance decisions are made during such events. Additionally, Tim addresses the challenges of evolving governance as more stakeholders join and changes become more complex. He shares insights on initiatives like Protocol Guild that support core developers and mentions funding opportunities through grants for infrastructure development. Questions from attendees revolve around how African communities can contribute to infrastructure development and engage with ongoing initiatives. Tim suggests building high-quality infrastructure providers for geographical decentralization and connecting local payment systems to blockchain on-ramps as potential areas for contribution. He also highlights funding sources like the Ethereum Foundation's grants program (ESP) and other L2s or DAOs interested in developing their ecosystems. Finally, there's excitement about DevCon's Scholars Program that funds community leaders to attend DevCon events and a
