With Yordan Barzakov (ReVizia, moderator), Alexander Sverdlov (Atlant Security), Daniel Babbev (Bitcoin Suisse) and Dr Boyan Torosov (Bulgarian Academy of Sciences). Moderated by Yordan Barzakov, the panel moves from today's hacks to tomorrow's quantum threat. Alexander Sverdlov dissects a 351 million dollar exchange breach from the day before and argues that cryptography rarely fails, while implementations, transaction monitoring and threat modelling do. Dr Boyan Torosov explains qubits and error correction, says Google's estimate of under 500,000 physical qubits depends on its assumptions, and expects a fault-tolerant machine able to run Shor's algorithm at scale within the next decade or so, while Daniel Babbev calls harvest now, decrypt later far-fetched, points to public keys already exposed on chain and warns that migrating Bitcoin to post-quantum signatures is a governance problem rather than a technical one. Sverdlov closes by urging institutions to deploy unconstrained AI for defence now. Panel at Future Finance Forum 2026, 25 September 2026, Sofia. Part of Blockchain Week Bulgaria 2026.

Ansgar Dietrichs

ETHGlobal · Jul 9, 2026

In this talk, Ansgar Dietrichs from the Ethereum Foundation, who has been in Ethereum core research for seven years, currently leads scaling work and co-leads the Okodas governance process, shares personal reflections on Ethereum's role in what he calls the decade of adoption. He frames the first 10 years of blockchains (2014 to 2024) as the infrastructure era requiring countless zero to ones across wallets, transaction supply chains, and the entire tech stack. He argues 2024 marked the ChatGPT equivalent moment for crypto, but unlike AI's single inflection point, it was a perfect storm of the tech stack reaching maturity, the US regulatory environment shifting from open hostility to a friendly stance, and stablecoins finally hitting product market fit beyond crypto native use cases. Ansgar contrasts two possible futures for crypto. The bad outcome is a fragmented world of independent chains (general purpose, app chains, privacy chains, permissioned chains) all linked by brittle custom bridges that have repeatedly failed and require each user to reason about every chain's security model independently. Ethereum's answer is a singular foundational framework that embraces all that customization but routes everything back to a shared settlement layer, enabling trustless interoperability between any pair of chains or assets, propagated security guarantees from Ethereum L1, full customizability at each layer, a single entry point for users, and ETH as the one native asset across the onchain economy. He explains the EF's pivot toward being one node among many ecosystem stewards rather than the center of Ethereum, then defends Ethereum's values as deeply practical rather than overly ideological. He cites security through redundancy across 10+ Ethereum clients being especially crucial during the coming AI driven cyber security arms race, Ethereum's principled postquantum planning while other chains scramble, and neutrality and strategic reliability under what he calls the Amazon test: would a big tech company comfortable trust putting its business flows on Ethereum knowing it could never be rugged. 00:00 Introduction 00:11 Ansgar's Background at the Ethereum Foundation 00:52 Why ETHCom Is Emblematic of a New Time Period 01:16 The First Decade of Blockchains: 2014 to 2024 02:11 The ChatGPT Moment for Crypto 02:41 Three Forces: Tech, Regulation, and Stablecoins 03:24 Entering the Decade of Adoption 03:48 The Bad Outcome: A Fragmented Future 04:51 Why Brittle Bridges Are the Bigger Problem 05:41 Ethereum's Answer: A Singular Foundational Framework 06:18 Why a Shared Settlement Layer Wins 06:47 Trustless Interoperability Across All Chains 07:35 Aspirational Today, Priority for Adoption Era 07:57 Propagating Ethereum's Security Guarantees 08:31 Full Customizability with Ethereum as Entry Point 09:12 ETH as the Native Asset of the Onchain Economy 09:43 The EF as One Node Among Many Stewards 10:48 Embracing the Ethereum Way of Decentralization 11:52 Why Ethereum's Values Are Misunderstood 12:11 Why Principled Equals Practical 12:34 Security: 10 Clients and 100% Uptime 13:03 The Coming AI Cybersecurity Arms Race 13:52 Quantum Resistance and the Beam Chain 14:54 Neutrality and Credible Neutrality 15:23 Why Censorship Resistance Matters for Institutions 16:31 Strategic Reliability and the Amazon Test 17:58 Useful Across the Spectrum 18:29 The Four Step Plan for Ethereum 19:51 Closing: Ethereum's Best Time Is Yet to Come _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *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 core idea is to maintain compacted, flattened, and fine-grained (i.e., transaction-level) historical states by flattening the minimum state changes of each transaction required for the world state. 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

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

The talk will also be an update of the implementation work with the adoption of the right in the Constitution of Geneva voted with 94% approval rate on the 18th of june 2023. The video features a talk by Alex Roussel, CEO of NIM Technologies, on the topic of digital human rights and the concept of digital integrity. Roussel discusses his work on making the idea of digital integrity a recognized right, drawing parallels with physical and mental integrity protected by laws. He shares his success in getting 95% of voters in Geneva to approve a new digital right in 2023. Roussel explains that digital integrity should be an extension of existing rights, ensuring individuals have control over their personal data and are protected from non-consensual use of it. He emphasizes the importance of anonymity and privacy infrastructure, mentioning that NIM is building a mix net and VPN to support these goals. The talk also covers how digital integrity can be integrated into legal systems, citing examples from Switzerland where new rights have been added to the constitution. Roussel argues for transparent societal systems where personal data remains anonymous, allowing for private interactions between individuals. He concludes by stressing the need for decentralized, anonymous systems to protect against misuse by generative AI and other threats. The talk ends with audience questions on how simply adding "digital" to existing rights can effectively convey the necessary protections in legal contexts, with Roussel explaining how jurisprudence would adapt over time to refine these rights.

Clip The video features Jiahao Sun, the founder and CEO of Flock, discussing the company's mission and technology. Flock is a pun for federative learning blockchain, an idea stemming from a paper published in NeurIPS 2022 and further detailed in the journal "Transitioning AI." Jiahao's background includes working in traditional finance as head of AI at Eurobank Canada and as a researcher at Imperial College London. Flock aims to solve data silo issues in industries like finance and healthcare by combining federated learning with blockchain technology. Federated learning occurs on devices like smartphones, where data stays local while only model weight changes are sent to improve collective models. However, there's a risk of centralized control and data misuse, which Flock addresses using blockchain for transparency and security. The platform introduces an incentive mechanism where good behaviors are rewarded, and bad actors are penalized, ensuring honest participation. The system uses random selection for proposers who contribute to model training and voters who validate results. Malicious attempts are thwarted through this process, maintaining high accuracy even with a significant presence of bad actors. Jiahao also discusses experiments with the Kaggle Learning Club dataset that demonstrate the effectiveness of Flock's approach compared to traditional federated learning under malicious conditions.

The discussion also explores how non-delegating proposers can exist but face difficulties participating in the current PBS system. The speaker suggests that high proposer participation is crucial for the vision of universal synchronous composability to be realized with high utility. Opinions on whether it's acceptable for all participants to delegate in the short term are shared, acknowledging that this is a contentious issue. The conversation shifts to issues of roll-up fragmentation, user experience challenges due to liquidity fragmentation across different roll-ups, and potential solutions like shared sequencing protocols. However, concerns about censorship resistance and sovereignty loss for roll-ups are raised. There's also a debate on whether L1 proposers will sequence for L2s and how pre-confirmation gateways might be allocated via a registration smart contract on L1. The video concludes with technical discussions about possible implementations, including using SGX for trust issues and how MEV could flow back to L2s through auction mechanisms. Overall, the video presents a deep

Clip The video features the co-founder of Radius discussing their approach to using basic sequencing for the decentralization and unification of ROLIPS. The talk covers the importance of basic sequencing in ensuring safety, censorship resistance, and liveness during the pre-settlement step of ROLIPS transactions. The presentation explains how ROLIPS inherits decentralization from Ethereum during the settlement phase but lacks these properties in pre-settlement. The speaker proposes a solution involving incentive alignment between users and Ethereum proposers to ensure transaction safety before they are sent to Ethereum. The talk delves into the challenges of achieving decentralization without causing layer 1 centralization or relying on sequencer and proposer relationships. It introduces a delegation contract as a potential solution, which involves a complex interaction between sequencers, builders, and proposers to hedge operational risks through auctions and contracts. Furthermore, the presenter discusses risk management strategies for builders and profit opportunities for sequencers while maintaining censorship resistance through an encrypted mempool that ensures transactions are processed without bias. Lastly, a liveness solution called RAFT is mentioned to handle sequencer failures. The speaker concludes by inviting discussion on further ideas for achieving decentralization in ROLIPS, particularly focusing on safety with basic sequencing and addressing challenges related to liveness and avoiding layer 1 central

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
