Kartik Talwar, Simona Pop

ETHGlobal · Sep 9, 2026

In a live HUMAN Protocol podcast recording, host Simona Pop interviews ETHGlobal Co-Founder and CEO Kartik Talwar about the invisible work behind a durable developer community. Talwar reflects on ETHGlobal’s history, its early Ethereum Foundation support, and the standards learned from organizing events at global scale. Community quality, he explains, depends on thousands of decisions that participants rarely see: reviewing every applicant, helping teams find the right environment, gathering feedback at high volume, and creating clear pathways from a first hackathon to a serious company. Pop asks how ETHGlobal defines quality when event size, application volume, and the surrounding market continue to change. Talwar describes maintaining a consistent bar by reviewing applicants individually and creating an environment where builders can compare themselves with exceptional peers. The conversation follows projects and people from early experiments through products that shaped the Ethereum ecosystem, showing how trusted communities compound over time. Talwar discusses staying close to builders, recognizing what “good” looks like, surviving uncertainty, and expanding without abandoning careful curation. He also considers open source, software-driven business infrastructure, and the falling cost of building every layer of a business, which creates new demands for developer platforms and community operators. The central lesson is that community is not an audience metric: it is ongoing operational labor that helps talented people meet, test ideas, learn faster, and continue building through changing market cycles. They also discuss the difficult years between visible successes. ETHGlobal benefited from early timing and Ethereum Foundation support, but endurance required careful curation, staying close to builders, and continuing to serve developers through difficult market cycles. 00:00 Introduction and Live HUMAN Podcast 01:43 Kartik Talwar’s Academic Background 03:57 From University to Open Source Software 04:45 Learning Startups at SV Angel 06:40 Learning What Great Founders Look Like 08:44 Why the Hackathon Format Matters 10:51 Giving Builders Access to New Technology 11:47 Hack the North and Practical Education 13:32 Feedback Loops for Developer Platforms 14:25 Measuring Time to First Project 15:30 Hackathon Feedback Improves Products 17:22 Giving Builders More of Thirty-Six Hours 18:20 When Local Nodes Took Hours to Sync 19:27 From Better Tooling to Better Products 20:46 CryptoKitties and the First NFTs 22:09 Gitcoin Founders Meet at a Hackathon 22:53 A MetaMask Bug Fixed in the Room 23:19 How 1inch Emerged From Hackathons 26:38 Building Through Every Bear Market 28:03 Reviewing Every ETHGlobal Applicant 29:17 Helping Builders Find Their Peers 29:38 Playing the Seven-Year Community Game 30:38 Showing Real Work During Bear Markets 33:05 Reviewing Every Project and Trend 35:00 Early Ethereum Foundation Support 37:20 Scaling Events After COVID 40:33 The Clash Between Ideals and Reality 42:05 Open Source and Community Compounding 42:36 Supporting Every Layer of a Business 45:01 The Opportunity in Crypto Infrastructure 46:18 Faster Experiments and Product Feedback 48:28 Patterns Across Hundreds of Companies 49:36 Open Source as a Community Model 50:01 Why Closed Ecosystems Backfire 51:42 Competing in the Same Room 53:04 Short-Term KPIs Create Silos 53:53 Long-Term Foundations Versus Easy Wins 55:01 Final Thanks and Podcast Sign-Off _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇵🇹 *Pragma Lisbon 2026* Pragma Lisbon 2026 was held on June 25th at the Carlos Lopes Pavillion in Lisbon, Portugal and was an in-person summit for builders and leaders in the web3 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!

In this welcome and opening ceremony, Kartik Talwar, co-founder of ETHGlobal, opens ETHGlobal Lisbon 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 trying out ideas, learning new skills and protocols, and the belief that showing beats telling, so on Sunday everyone demos what they built to judges, partners, and each other. He traces ETHGlobal's history from the first 2017 event in Waterloo through global expansion across six continents, notes the 2026 events in Cannes and last month's New York, and welcomes everyone back to Lisbon for the second time. This weekend brings over 518 attendees (380 hackers, 26% coming from web2), from 116 cities, 47 countries, and six continents, plus 43 partners, 16 technical mentors, eight workshops, zero talks, and $100,000 in prizes across eight partners: 1inch, 0G, Hedera, Sui, The Graph, Uniswap Foundation, World, and ENS. Kartik walks through key logistics and rule changes. Hacking has begun, teams can have up to five members, and submissions are due Sunday at 9am. He encourages using LLMs and AI coding tools like Codex and Claude Code but recommends committing plan markdown files and frequent descriptive commits so work is traceable, sharing SDK feedback with partners, and avoiding four AI pitfalls (do not use AI-generated ideas, get real human feedback, do not just delegate, and always understand your own code). He introduces the continuity track, letting hackers extend a past project, fix an open source bug, or ship an open source module into private code, with track-specific prizes. He covers venue security, Wi-Fi etiquette, Discord support, food, a tile-painting activity, swag, and four spotlight teams. On judging, he explains the partner track (apply to up to three of the eight partners) versus the finalist track (top 10 teams demoing live on stage) with an auditable repo, live deployment, and video demo required, and finalist perks like ETHGlobal Plus, $1,000 cash, flight credits, and AWS credits. He brings on Matt from 1inch, who shares that 1inch began at a 2019 hackathon and has since done over $800 billion in volume, and introduces the $7,000 in bounties for building Aqua apps, a liquidity provision method that keeps tokens in the LP's wallet. 00:00 Introduction 00:11 Welcome: This Is a Hackathon, Not a Conference 00:37 What Makes ETHGlobal Events Different 00:54 Why Showing Beats Telling 01:18 The History From 2017 to Today 02:25 Back in Lisbon for the Second Time 02:31 Who Is Here This Weekend 03:05 Partners, Mentors, and Workshops 03:27 $100,000 in Prizes and the Eight Partners 04:28 The Hackathon Has Begun 05:07 Team Rules and Submission Timing 05:42 Using LLMs and AI Coding Tools 06:25 Committing Plan Files and Sharing Feedback 07:24 The Four AI Pitfalls to Avoid 07:47 Why Not to Use AI-Generated Ideas 08:23 Why to Get Real Human Feedback 08:42 Why Not to Just Delegate 09:33 Introducing the Continuity Track 09:55 How to Continue a Past Project 10:55 Extending Open Source and Private Projects 12:08 How to Select Your Track 12:59 Venue Security and Badges 14:05 Wi-Fi Etiquette and No Hotspots 15:00 The Website and Discord 16:29 Venue Layout and Pragma 17:02 Food and Activities 17:53 Swag and Giveaways 18:40 The Four Spotlight Teams 19:54 Judging and Prizes: The Two Tracks 20:19 The Partner Track 20:57 The Finalist Track 21:55 Why Become a Finalist 22:32 The Requirements to Be a Finalist 23:50 Demoing Live to Judges 24:47 The Finalist Demo Format 25:09 Why Not to Record Your Video Last Minute 26:28 How First-Come Judging Works 27:32 The Mentors Who Can Help 28:29 Rules, Respect, and IP Ownership 29:42 Bringing On Matt From 1inch 30:55 Introducing the Aqua Protocol 32:00 The 1inch Bounties 33:39 Recapping the Prizes and 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!

ETHGlobal · Jul 9, 2026

In this talk, Lindsay Fraser, who leads policy at the Blockchain Association, explains what the Clarity Act means for developers. The Blockchain Association is a nonprofit that advocates for the digital asset industry in Washington DC with over 100 member companies. She notes the timeliness: the day before, the association brought over 30 member companies to DC and met with 52 different Senate offices amid active negotiations. The Clarity Act is the current name for market structure legislation moving through the US Senate, the result of years of bipartisan effort dating back to 2020. At a high level it does three things: establishes token classification, trading, and market rules (fixing the impossibility of building in the US without clear rules during the Gary Gensler era at the SEC); sets registration requirements and consumer protections for intermediaries across the SEC and CFTC; and defines developer rules and protections outlining what software builders are and are not regulated for, the crux of the current debate. Lindsay explains why clarity matters: for years developers lacked answers to whether publishing code, operating a front-end, or participating in governance are regulated activities, and regulation by enforcement drove developers offshore. She walks through the process: the House passed it last June with 294 votes including 78 Democrats, the Senate Agriculture Committee advanced its portion 12 to 11 on party lines, and the Senate Banking Committee recently voted its portion out with a bipartisan outcome, with the two bills now to be combined and reach 60 votes to bypass the filibuster before November midterms complicate things. She details three developer protections: Section 601 clarifies the 1933 and 1934 Acts so non-custodial developers are not intermediaries needing to register as exchanges, brokers, or dealers; Section 207 does the same under the Commodity Exchange Act for the CFTC; and Section 604, the Blockchain Regulatory Certainty Act (BRCA), shields non-custodial developers from Bank Secrecy Act obligations and prosecution under Section 1960 for unlicensed money transmission. She frames the BRCA as a codification of 2019 FinCEN guidance, counters law enforcement opposition as a mischaracterization (noting titles 2 and 3 strengthen prosecutors), and cites a letter from 160 officials plus 60+ CEOs, closing that developer protections must remain intact. 00:00 Introduction 00:11 Who the Blockchain Association Is 00:40 Meeting 52 Senate Offices in One Day 01:24 What the Clarity Act Aims to Do 01:50 The Three Buckets of the Bill 01:57 Token Classification and the Gensler Era 02:22 Requirements for Intermediaries 02:44 Developer Rules and Protections 03:09 Why Clarity Matters for Developers 03:34 The Unanswered Questions Builders Face 03:56 How Regulation Drove Developers Offshore 04:22 Drawing a Line Between Software and Intermediaries 04:51 Where We Are in the Process 05:13 The Overwhelming House Vote 05:35 The Senate Agriculture Committee Vote 05:58 The Bipartisan Senate Banking Vote 06:19 Combining the Bills and the 60-Vote Threshold 06:45 Why the Midterms Add Urgency 07:06 The Three Core Developer Protections 07:24 Section 601 and the 1933 and 1934 Acts 07:46 Protecting Non-Custodial Developers 08:36 Section 207 and the Commodity Exchange Act 08:50 The Key Line of Custody and Control 09:10 Section 604: The Blockchain Regulatory Certainty Act 09:41 The Threat of Section 1960 Prosecution 10:28 The Cost of Investigations on Founders 10:59 Why the BRCA Must Not Be Watered Down 11:22 A Codification of 2019 FinCEN Guidance 11:57 The Bipartisan History of the BRCA 12:53 The Opposition From Law Enforcement Groups 13:22 Why the Opposition Mischaracterizes the BRCA 13:52 How Titles 2 and 3 Strengthen Prosecutors 14:38 The Letter From 160 Law Enforcement Officials 15:50 The Industry Letter From 60 CEOs 16:16 Why Developer Protections Must Be a Priority 16:49 A Call to Share Developer Stories 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.

The video features a talk by Andy, the CEO of BlockSec and a professor at Zhejiang University, discussing their research on optimizing Ethereum archive nodes. The research is a collaborative effort between BlockSec, students, and other partners. Andy emphasizes the importance of building real systems with tangible impacts and outlines BlockSec's role in enhancing blockchain security through various products and solutions. Andy explains that blockchain optimization can be achieved at different layers, including consensus mechanisms, execution layers, and storage engines. Their work focuses on optimizing the storage engine to improve efficiency and reduce costs by modifying the state model within Ethereum's archive nodes. He provides an overview of Ethereum's storage layer, explaining that it operates as a state machine driven by transactions that change states. The state is an account-based model with each account having its own storage referenced by a storage root. All states are encoded in a Merkle Patricia Tree (MPT) for quick data authentication. Different types of Ethereum nodes exist with varying capabilities regarding historical data storage. Full nodes only maintain the latest world state for reorganization tolerance while archive nodes preserve all historical states but require significant disk space due to saving all intermediate MPTs at each block. Archive nodes are essential for detecting transaction attacks and smart contract vulnerabilities through historical transaction analysis. They also help

Clip This video discusses a new model for pre-confirmation in cryptocurrency transactions that reduces the required collateral from 1,000 ETH to just 1 ETH. The speaker explains the original rationale for the high collateral amount was to cover the worst-case scenario of maximum extractable value (MEV) in a single block. However, this approach is costly as it requires overpaying for security every time. To improve this, a distinction is made between inclusion pre-confirmations, which guarantee a base fee and are economically beneficial when there's no contention on state, and execution pre-confirmations, which are more complex and relate to trades like Uniswap transactions. The speaker proposes an insurance market model where users pay for coverage based on the actual risk of price movement during transaction confirmation time rather than a flat worst-case fee. This model allows solo validators with minimal collateral to provide pre-confirmations and introduces benefits such as increased access for solo stakers, better risk-reward balance, and stronger user assurance through insurance rather than sheer collateral amount. The video also addresses potential user experience aspects, how wallets could handle these changes, and how trust networks might impact gateway reputations.

Clip The video presents a discussion on how to reinvent the protocol buffer (PBS) space, specifically focusing on Layer 1 (L1) pre-confirmation protocols and their integration with wallets for gas fee hedging. The speaker represents a research and product company in the blockchain financial primitives sector. They introduce a mental model where rollups act as block space dealers, buying space from L1 and reselling to Layer 2 (L2) users. The talk outlines the current issues with high L2 transaction submission costs due to inefficient packing and non-deterministic block confirmation times. A solution proposed is based on pre-confirmation, aiming to reduce confirmation time significantly and lower transaction costs. The speaker delves into the concept of proposal commitment, which includes an optimistic mechanism, EVM state changes, state dependencies, and a challenge mechanism for penalizing non-compliance. They address the "cold start" problem of getting enough validators to opt into the pre-confirmation network and suggest using pre-conf delegation as an initial strategy. A go-to-market strategy is discussed, drawing lessons from MEV-Boost's adoption journey by minimizing risk for proposers and simplifying their opt-in process. The talk also touches on potential issues of centralization and censorship resistance that can arise from delegated pre-conf

Clip The video features a researcher from Primav discussing the concept of pre-confirmation in blockchain transactions, specifically within the context of Ethereum. Pre-confirmation is a mechanism that provides users with a fast guarantee that their transaction will be included in the next block, improving user experience and potentially increasing profit for activities like arbitrage. The researcher explains the roles of two main actors in this system: bidders, who are willing to pay for pre-confirmations, and pre-confirmation providers, who can credibly promise transaction inclusion. Primav has developed MavCommit as an open network where anyone can participate as either role. The talk delves into why block builders might provide pre-confirmations, emphasizing their specialized knowledge and capability to do so quickly and economically. However, since multiple builders compete to build blocks, a pre-confirmation from one does not guarantee inclusion if another builder is selected. The speaker suggests that even probabilistic pre-confirmations can be valuable for certain strategies like cross-chain arbitrage. Primav's solution includes a side chain with fast block times for settlement and a decay mechanism incentivizing timely pre-confirmations. The protocol also emphasizes privacy for bids and commitments through encryption and special cryptographic commitments. In conclusion, MavCommit aims to offer an open network with strong cryptographic guarantees for timely

Clip The video features a presentation by Daniel Ivanov from Limechain, who discusses the research and development of vanilla-based sequencing and preconfirmations in the context of roll-ups and blockchain interoperability. Funded by a grant from the EF, their work aims to provide neutral solutions for these technologies. The talk covers four major design decisions: discovery, leader selection, preconfirmation types, and integration with the L1PBS pipeline. Daniel explains various options for each design aspect and their implications for wallets, users, builders, relayers, and proposers in the blockchain ecosystem. He emphasizes the importance of standardizing certain aspects to achieve unmatched interoperability and rationalizes the current social consensus on preconfirmations. Daniel acknowledges that there are differing opinions within the community and seeks to establish a socially accepted view. Several scenarios are presented regarding how transactions are propagated among different actors (builders, relayers, proposers) in the network. The pros and cons of each scenario are examined, particularly focusing on issues like trust, delegation, and potential slashing risks for proposers. Daniel highlights the need for an EIP on the builder API as one of the missing pieces to move forward collaboratively but not fragmented. He concludes by posing questions to the community about improving these systems further. The presentation ends with a

Panel discussion The video features a panel discussion on the viability and sense of pursuing base sequencing within a firm's research team. Initially, one member was highly supportive, while others were more cautious. The panel seeks to gauge current opinions on the topic, with participants scoring their support out of 10 and discussing their reservations or questions. Barnaby, who has thought about base sequencing the least, rates his support at 4 out of 10 due to having more questions than answers. He expresses uncertainty about pre-confirmations and wonders how much he needs to buy into the whole package versus selecting parts that make sense to him. Bankrat is generally supportive of base sequencing but skeptical about centralizing all sequencing and proving in one place. Vitalik echoes this sentiment, supporting base roll-ups but expressing concern over the practicalities of achieving low latency for guaranteed transaction speeds. The panel delves into various technical aspects of base sequencing, such as synchronous versus asynchronous transactions, centralized versus decentralized sequencers, and potential centralization risks. They also discuss user experience improvements such as cross-rollup operations feeling unified and seamless. The conversation touches on economic incentives for applications to become their own roll-ups to capture congestion fees and how this might lead to a more diverse ecosystem. Ultimately, the panelists agree that from a user
