19:47Proof Over Promises | Deepthi Kumar (o1Labs) at ETHConf
ETHGlobalJul 9, 2026
In this talk, Deepthi Kumar, co-CEO of O(1) Labs, the team behind Mina Protocol, makes the case for moving from trust based to proof based enterprise systems. She frames the central problem facing every business in the coming years: increasing reliance on systems, vendors, and AI agents that you cannot actually check. Her thesis fits in one line: make trust verifiable. Rather than handing over more promises about what systems can do, organizations should hand over more proofs. She notes that zero knowledge proofs have quietly gone mainstream beyond cryptography papers and private tokens, with Google shipping ZK age verification in Google Wallet, Microsoft integrating ZK based credentials into its identity offering, and the EU mandating ZK based digital identity for member states. Deepthi explains that ZK has historically been used for two purposes (privacy and scalability through ZK rollups), but proposes a third use case: verifiability, which is an inherent property of ZK rather than something bolted on. A SNARK at its core is verifiable computation. She argues this should be applied to enterprise workflows where policies govern high stakes operations, citing two converging forces driving the urgency: AI as an offensive weapon (with the first AI generated zero days being reported and threat actors using AI across attack lifecycles), and AI as an actor (agents acting on our behalf at a scale existing guardrails cannot match). The proposed shift is from a model where you trust systems to act, to one where the highstakes action is logged until a proof shows up validating that all policies were enforced. She describes ZK as a "knot tree" that cannot be bribed. The mechanics are three steps: encode existing policy into a ZK circuit running in parallel to existing enforcement, verify the proof against the expected statement, then execute the operation. Benefits include cryptographic receipts, per action audit trails (finer than sample checks), and composability across multi organization workflows through proof aggregation. She closes by emphasizing this is additive not replacement (preserving security heterogeneity), incrementally adoptable starting with one narrow high value flow, and applicable to institutional finance money movement, AI agent identity and delegation, and any vendor integration with policy enforcement requirements. 00:00 Introduction 00:10 Why You Cannot Check Your Vendors and Agents 00:54 Proof Over Promises 01:33 ZK Has Quietly Gone Mainstream 02:17 Google, Microsoft, and the EU on ZK 02:46 The Two Established Uses: Privacy and Scalability 03:42 Proposing Verifiability as the Third Use Case 04:17 Why Verifiability Is Inherent to ZK 05:05 Why Now: Two Forces Pushing in the Same Direction 05:50 AI on the Offense 06:26 AI as an Actor on Your Behalf 07:01 Shifting From Trust to Proof Authorization 07:47 ZK as a Knot Tree That Cannot Be Bribed 08:22 Treasury Transfer as a Concrete Example 09:24 Verifiable Workflow in Three Steps 10:03 Encoding Policy Into a ZK Circuit 10:44 Verifying the Proof Statement 11:27 Cryptographic Receipts 11:54 Per Action Audit Trails 12:19 Composability Across Multi Organization Workflows 13:44 Not Rip and Replace, Additive Layer 14:51 Why ZK Adoption Can Be Incremental 15:45 Applications: Institutional Finance Money Movement 16:27 AI Agents Proving They Followed Policy 16:53 Agent Identity and Delegation Chains 17:21 Enterprise Operations and Vendor Integrations 18:02 Key Takeaway: Add a ZK Layer to High Stakes Operations 19:01 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.

18:34Social Contracts for Web3 Coordination I Tushar Ojha
ETHGlobalNov 9, 2025
Tushar Ojha, founder of True Network, discusses the concept of onchain reputation as a new primitive for Web3 social contracts, arguing that reputation is superior to capital for scalable, trustless coordination. He critiques current blockchain systems that rely on capital staking, highlighting their scalability and centralization issues. Ojha proposes using reputation—earned, non-transferable, and costly to fake—as a portable, plural asset for coordination, governance, and accountability. He references historical uses of reputation in governance (Akbar, Ashoka) and explains how blockchain enables immutable, transparent, and verifiable reputation systems. True Network enables protocols to issue attestations, build reputation models, and leverage reputation as an asset in social contracts, enabling use cases like onchain tournaments, improved governance, and Sybil resistance. He encourages the Web3 community to build on this narrative, sharing examples from ETH India and announcing the Ramen Network testnet. Ojha concludes that the time for onchain reputation has arrived. 00:00 Introduction 00:42 The Value of Reputation in Web3 01:15 What Problem Does Web3 Solve? 02:22 Perspectives on Blockchain: Credible Commitments & Trust 03:23 Coordination Without Trust 04:28 Capital-Based Alignment: Limitations 05:22 The Cost of Capital in Blockchain Security 06:03 Reputation as a New Primitive 07:05 Implementing Reputation: Challenges & History 08:40 Historical Reputation Systems: Akbar & Ashoka 09:07 Why Blockchain Reputation Systems Can Succeed 09:26 Credible Neutrality & Onchain Reputation 09:55 True Network: Architecture & Attestations 10:49 Identity, Credentials, and Reputation Models 11:41 Social Contracts: Programming Reputation 12:42 Formal Definition of Social Contracts 13:41 Use Cases: Games, Governance, and Accountability 15:04 Efficiency and Inclusivity of Reputation-Based Systems 15:51 ETH India: Building the Reputation Narrative 16:14 Example Projects: Fanbase & Placeholder 17:13 Community, Testnet, and Future Vision 17:46 Mission and Closing Remarks 18:08 Conclusion & Call to Action _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *Pragma New Delhi* Pragma New Delhi 2025 was held on September 25th at the JW Marriott Hotel in Aerocity New Delhi and was an in-person summit for builders and leaders in the web3 ecosystem.

Panel discussion: Securely Scaling Ethereum
ETHTokyoSep 21, 2024
Discussing how to scale Ethereum to the next billion of the world. In this video, a panel discussion on scaling Ethereum securely features experts from different projects in the crypto space. The panelists discuss the future of Ethereum scalability, prioritizing security, usability, and decentralization. They explore the concept of endgame for Ethereum, touching upon topics like rollups, zero-knowledge proofs (ZKPs), and the importance of privacy in transactions. The conversation also delves into the trade-offs between scaling at layer one (L1) and layer two (L2), the role of rollups in Ethereum's future, and the challenges related to interoperability between different rollups. Additionally, they address whether Ethereum should cater to web3 or web2 use cases and the potential of using Ethereum for everyday transactions like buying coffee. The video concludes with a Q&A session from the audience.
A security in depth approach to verifiable offchain computations
EthCCAug 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
Universal Proof Aggregation for Scaling, Privacy, and Interoperability by Shumo Chu
ZuBerlinJun 14, 2024
Clip The video features a co-founder of a blockchain technology lab discussing the concept of Universal Proof Aggregator (UPA) for enhancing scalability, privacy, and interoperability in blockchain networks. The speaker begins by explaining the importance of maintaining decentralization in blockchains and argues that proofs, especially zero-knowledge proofs, are key to achieving scalability and privacy without sacrificing decentralization. They introduce the Nakamoto coefficient as a measure of decentralization and provide an overview of how different blockchain networks rank in terms of node count and decentralization. The talk then delves into the technical aspects of UPA, including its role in aggregating multiple proofs into one to reduce on-chain verification costs and improve efficiency. The speaker outlines the challenges faced during development, such as handling non-native arithmetics and supporting various proof systems. They also highlight their testnet launch and discuss future directions for UPA, including adopting a VM-based architecture for greater generality. Finally, they touch briefly on interoperability within blockchain ecosystems, emphasizing its importance for user experience and security. Due to time constraints, this section is not explored in depth. The presentation concludes with an invitation for collaboration and a single audience question about settlement finality in the context of UPA and cross-chain transactions.
Kick-Off Day 1
ZuBerlinJun 11, 2024
Kick off with Justin The video features a comprehensive discussion on base sequencing, a layer one sequencing technology for roll-ups on the Ethereum blockchain. The speaker provides an introduction to the concept, detailing its decentralized and neutral nature, and emphasizes its importance as a public good for the ecosystem. The talk covers the desired properties of block space on Ethereum, such as security, programmability, scalability, low latency, and composability. A vision for "the United Chains of Ethereum" is presented where different roll-ups operate seamlessly together, enabling synchronous composability and super transactions across multiple domains. The speaker introduces the idea of pre-confirmations that execute within 100 milliseconds and discusses technical solutions for achieving this speed and synchronous composability between roll-ups. They explain the need for real-time proving and liquidity providing as interim solutions until real-time proving becomes viable. Additionally, they outline a roadmap for implementing base sequencing with technical details such as inclusion pre-confirmations and execution pre-confirmations. The role of L1 proposers in pre-confirmations is examined along with the concept of underwriters providing collateral to ensure the integrity of pre-confirmations. The talk concludes with a roadmap highlighting upcoming milestones such as development networks (DevNets), long-running testnets at major Ethereum community events, and potential mainnet implementation.

26:19Ethereum's L2 Limitations: Need for More! | ETHDenver 2023
Ethereum DenverOct 9, 2023
n this video, we delve into the fascinating topic of L2 (Layer 2) solutions in the Ethereum ecosystem. Join us as we explore the limits of these solutions and challenge the common belief that they are enough to scale Ethereum effectively. We'll dive deep into the trade-offs associated with L2s and shed light on why they may not be suitable for every use case. Scaling Ethereum is a complex task, and while L2s have emerged as a dominant solution, it's crucial to understand their limitations. By examining these limitations, we can gain valuable insights into why additional solutions are necessary to address scalability concerns comprehensively. Throughout this discussion, we acknowledge that bridging technology to other chains introduces risks that need careful consideration. Our aim is to provide you with a comprehensive understanding of how L2s fit within the broader context of scaling Ethereum and highlight alternative approaches that can complement or even surpass their capabilities. Join us in this thought-provoking exploration of L2 solutions in the Ethereum ecosystem, where we unravel their true potential and discuss what lies beyond them. #Ethereum #Scalability About the Speaker: Martin Köppelmann is a seasoned blockchain entrepreneur with over 9 years of experience. He holds a pivotal role as a leading contributor at the GnosisDAO. The DAO has created numerous essential infrastructure solutions for the Ethereum blockchain, including the widely utilized Safe Multisig wallet. With over $29 Billion in digital assets under its management, it's a testament to their work. Martin's current objective is to build the Gnosis Chain; a community-run, credibility neutral public blockchain network. TLDR: Layer 2 solutions may not be the ideal solution for scaling Ethereum due to security concerns, limited scalability, high fees, centralization, and potential censorship, and it is important to consider trade-offs and values when deciding between L2 and other options. 00:00 🔒 L2s may not be the ideal solution for scaling Ethereum due to security concerns and the potential for fund loss, despite their initial purpose of bridging technology. 05:04 🚫 The scalability of Layer 2 solutions is limited by the size of the Layer 1 chain, making it unable to handle the potential number of users and transactions, as demonstrated by the example of Bitcoin and lightning. 09:20 🚫 L2 scaling limits on Ethereum result in high fees, making it economically infeasible to exit from L2 to L1 if the value on L2 is smaller than the exit fee, and not all applications can easily transition due to their complex state. 11:44 🔒 L2 platforms in the Ethereum ecosystem may not be efficient for certain applications, are centralized and have the power to censor transactions, making it difficult for decentralized exchanges to compete, and there is a risk of sequencers being forced to censor transactions due to legal pressure or KYC requirements. 16:33 📉 Exiting or going through L1 to L2 has high costs, but if assets are issued on the chain, the argument for L2 becomes less important; running your own full node for a native asset provides high security even if validators go malicious. 19:15 🔒 Altus is facing an upgrade problem due to Ethereum's instability, which poses a challenge for L2 solutions, and Gnosis is deeply integrated in Ethereum and advocates for more decentralized L1 block space. 22:06 🔒 L2s can expand Ethereum's block space by leveraging its decentralization, but investing in credible neutral block space is crucial for Ethereum's mission. 25:40 💡 Consider the trade-offs and values when deciding between L2 and other options, such as a chain like Gnosis Chain.

20:25Blockchain Scalability: Optimism - Rise of the Superchain | ETHDenver 2023
Ethereum DenverOct 9, 2023
In this video, we delve deeper into the fascinating world of blockchain scalability for the decentralized web. Building upon a previous Defcon talk, Karl Floersch acknowledges that while the earlier session provided high-level insights and visuals, this talk will take a more detailed and in-depth approach. The problem of blockchain scalability has been an ongoing challenge since its inception, and it remains a pressing issue even in 2023. Throughout this presentation, we explore the complexities surrounding blockchain scalability and how it impacts the decentralized web. We examine various factors that contribute to this challenge and discuss potential solutions that have emerged over time. From exploring different consensus mechanisms to analyzing network congestion issues, we leave no stone unturned in our quest for understanding. Join us as we unravel the intricacies of blockchain scalability and gain valuable insights into its implications for the decentralized web. Stay tuned for an enlightening discussion on how this long-standing issue is being addressed by experts in the field. #blockchainscalability #decentralizedweb #buidl TLDR: The key idea of the video is that a super chain, consisting of multiple chains with added security and scalability, can solve the scalability problem of blockchain and enable the creation of a vibrant open source community in the decentralized web. 00:00 📈 Karl Floersch proposes the idea of a super chain to solve the scalability problem of blockchain and provide real value to people in the decentralized web. 02:25 📈 Developers can write code without worrying about underlying computers, allowing for easy composition of smart contracts and the creation of a vibrant open source community, while scalability technology in the Ethereum ecosystem is leading to the development of abstraction layers for globally scalable applications like Twitter. 05:28 🔗 The superchain is a network of multiple chains that adds security and scalability, abstracting away the underlying infrastructure, but collaboration from the blockchain industry is needed for this step. 08:51 🔑 The L1 sequencer in the Ethereum ecosystem does not forge transactions, but rather discards those with invalid signatures, ensuring the integrity of the L2 chain; generalized derivation functions enable scalability and isolation of chains. 12:30 📨 Cross-chain messaging enables the transfer of messages between different chains, facilitating actions like processing withdrawals from the red chain on Ethereum. 14:19 🔗 Messaging between different chains is achieved by verifying a proof system, allowing the blue chain to authenticate messages from the red chain, while proof systems help reduce compute requirements for verifying chains. 17:02 🔗 Infinite chains and chain messaging can be achieved through coordination between sequencers, addressing the bottleneck of data availability by adding L1 data availability or using the plasma protocol, resulting in a horizontally scalable super chain. 19:28 🌍 We can create a future where decentralized compute and open source software are used to fund public goods and build the open source internet.
17:53Security & Interoperability in Disparate Scaling Topologies | ETHDenver 2023
Ethereum DenverOct 9, 2023
In this insightful video, we dive into the fascinating world of bridges and their crucial role in scaling technologies. Bridges serve as connectors that enable assets to be securely locked in one context and utilized in another. However, as our speaker highlights, this process is not without its challenges. We explore the intricate topic of security vulnerabilities and the potential risk of theft associated with bridges. Moreover, our discussion extends to examining the importance of considering trade-offs when implementing various scaling solutions like state channels. By understanding these trade-offs, we can make informed decisions that balance efficiency and security. Join us as we unravel the complexities surrounding bridges in scaling technologies. Gain valuable insights into how they function, their inherent risks, and strategies for mitigating those risks effectively. #Bridges #ScalingTechnologies Dr. K Co-Founder Quai Network TLDR: The key idea of the video is that scaling solutions for Ethereum must address the security vulnerabilities of bridges and consider trade-offs between different mechanisms like state channels, plasma, and ZK rollups to ensure data availability, validity, and synchronization. 00:00 💡 Scaling technologies require bridges to enable interoperability, but the inherent security vulnerabilities of bridges must be considered and addressed in the design of scaling solutions. 01:14 🔒 Ethereum must be locked in Ethereum before being used in optimism, posing risks; when considering scaling solutions, it's important to examine trade-offs like state channels and plasma, as different mechanisms have varying challenges in synchronization, validity, and data sharing, with ZK rollups offering high data availability and validity guarantees, while optimism provides high data availability but less rigorous validity guarantees. 04:00 🔒 Plasma have different data availability and validity levels, but formal verification and code audits can mitigate risks associated with bugs, while mechanisms like Roll-Ups provide ZK proofs for state transitions without relying on external trust or off-chain consensus rules. 06:23 🔒 Side chains and plasma face an oracle problem in communicating with Ethereum, requiring off-chain consensus mechanisms and validator sets, while continuous monitoring of scaling contexts is necessary for security. 08:11 🔒 We face ordering, data availability, and synchrony issues when running in an off-chain context, which can lead to loss of state and assets, requiring us to wait for chains to progress towards finalization. 09:40 🔒 Quiet Network is a scaling solution that mitigates risks and ensures synchronicity by enforcing reciprocal validation, providing atomic roll forward and backward, finalization in chain context, and scalability without sacrificing other scaling solutions. 13:26 📚 Qui Network is a hierarchy of merge mine blockchains that eliminates the need for oracles and synchronization, allowing for the creation of performance subnets that can scale horizontally with demand. 15:36 🔒 Eventual referencing allows for layer 2 speed, layer 1 security, and reliable transactions, while scalability issues are eliminated by dynamically increasing the number of shards to meet demand.
