A few welcoming words by the University of Zurich - Blockchain Center and Duct Tape; the main organizers of this conference.

In a fireside chat, Alexander Brunner of Home of Blockchain.swiss and Prof. Claudio Tessone of the UZH Blockchain Center sit down together to explore the shifting landscape of blockchain and cryptocurrency in Switzerland in the face of the European Union's new Markets in Crypto Assets (MiCAR) directive. This discussion comes at a crucial time as Switzerland's Crypto Valley celebrates a decade of significant achievements. The conversation will address pressing questions about Switzerland's future as a blockchain leader. They'll delve into whether the EU's regulatory moves, highlighted by MiCAR, signal a competitive threat or a new realm of opportunities for Switzerland. Key points include MiCAR's potential as a regulatory framework, its gaps, and its impact on Switzerland as a major blockchain innovator. Will Switzerland be able to maintain its edge in the blockchain arena amidst Europe's tightening grip on crypto regulation?

In this talk we'll dive into a so called Cryptonative economy and numbers revealed by the extensive report prepared by contributors of the PWNDAO. The report looks into on-chain traced revenues of various L1s, L2s and dapps. Categorizes the on-chain applications and looks at observable trajectory of on-chain usage.

In contrast to computerization, emerging technologies in finance are now increasingly contributing to appearance of new unregulated business models on the market making regulation of the ABCD framework of technologies (artificial intelligence (“AI”), blockchain, cloud and data (“Big
Data”) quickly becoming a firsthand matter of predominant importance for regulatory
authorities, which are mandated to ensure, first of all, preservation of the adequate protection of the market functioning. As DeFi is currently approaching the dominant design stage, its product design model would be more and more dictated by regulation, a pattern which is similar to most of the regulated industries, including the sector of finance. A persistent theme of this talk is the
currently changing approaches to regulation of technological risks following a rapid transition to the wholesale level leveraging of DeFi. Following the analysis of common usage examples of DeFi on complex financial market, the presentation looks at various factors behind currently changing regulatory paradigm, including the notions of public perception of technological risk,
modern state as a risk manager, more principle-based regulation (MPBR), as well
as the issue of DeFi facilitating egress from the legal system.

The expressiveness of Turing-complete blockchains implies that verifying a transaction's validity requires executing it on the current blockchain state. Transaction fees are designed to compensate actors for resources expended on transactions, but can only be charged from transactions included in blocks. In this talk, we show that adversaries can craft malicious transactions that decouple the work imposed on blockchain actors from the compensation offered in return. We introduce three attacks:(i) ConditionalExhaust, the first conditional Resource Exhaustion Attack (REA) against blockchain actors.(ii) MemPurge, an attack for evicting transactions from victims' mempools.(iii) These attack are augmented by GhostTX, the first attack on the reputation system used in Ethereum's Proposer-Builder Separation ecosystem. We empirically evaluate the attacks on an Ethereum testnet. The worst-case result we find is that by combining ConditionalExhaust and MemPurge, an adversary can simultaneously burden victims' computational resources and clog their mempools, to the point where victims are unable to include transactions in their blocks. Thus, victims create empty blocks, thereby hurting the system's liveness. The expected cost of a one-shot combined attack is $376, but becomes much cheaper if the adversary is a validator. For other attackers, costs decrease if censorship is prevalent in the network. ConditionalExhaust and MemPurge are made possible by inherent features of Turing-complete blockchains. Potential mitigations may result in reducing a ledger's scalability, an undesirable outcome likely harming its competitiveness.

Blockchain platfoms normally issue one domestic token to be used for financial transfers, governance and other functions. Some of them instead decided to issued two tokens, one for governance and the otherr for the remaining functions, including transactions fees payment. In the talk we dscuss some economic aspects of such chains.

This presentation distills insights from building four advanced UniswapV4 hooks: Liquidity Incentives, Dynamic Fees, Liquidity Management, and a Combo Hook.

I'll share the lessons learned and challenges we encountered, which should give other builders a good idea of what to expect and what to watch out for when developing UniswapV4 hooks.

This talk seeks to explore Ethereum-based solutions for Central Bank Digital Currencies (CBDCs) and Interoperability. Below there are the main topics and respective use cases & considerations to be explored.
1. Baselined CBDCs
2. Ethereum 2.0 (Eth2)
3. Consensys CBDC Solutions.
4. Quorum.
5. StarkWare.

The current state of blockchain analytics is limited. Traditional methods focus on basic data like events and calls, missing the depth of data processed by the EVM. Storage, an essential yet often overlooked component in EVM-compliant blockchains, is key to maintaining consistency, supporting smart contracts, conserving resources, and enhancing security.
Accessing and interpreting 'storage diffs' (changes in storage) at scale poses significant technical and computational challenges. Decoding these storage diffs is even more complex. A standard RPC method like getStorageAt method falls short in shedding light on storage changes. Moreover, the need to decode hashes of slots and keys adds another layer of difficulty, especially when dealing with hash maps without precise hash knowledge.
There’s a however a method to simplify the use of storage by indexing and decoding every storage and state change. This innovation allows analysts to effortlessly query and interpret data previously inaccessible to them.
We will showcase how storage diffs can be used to track token supplies without needing in-depth knowledge of their implementation and therefore streamline DeFi accounting processes. We'll demonstrate how fully decoded datasets provide powerful insights, even to analysts with limited expertise in blockchain or smart contracts.

While the importance of AA is widely acknowledged, there's no consensus on the best implementation. Different protocols experiment with multiple implementations, aiming to bring AA to the masses in various ways.

Since 2018, Argent has been championing the cause of AA within the Ethereum ecosystem and has built strong opinions over the years, now advocating native AA and networks such as Starknet.

An increasing number of new-generation Layer 2s are following Starknet’s lead, recognizing the importance of widespread AA in a blockchain’s value proposition. They are implementing native account abstraction while removing EOAs altogether, making AA a de-facto reality from day one. These chains are likely to lead AA adoption and be the first to capture new user bases.

The crypto token design space is highly diverse. Crypto tokens vary in purpose and technical characteristics, making a one-size-fits-all regulatory approach impractical. This talk will outline the legal framework for categorizing tokens as payment, utility, or asset tokens, along with the necessary protocol research to have an informed opinion about a token's classification

In this workshop, we walk through the full stack of a dapp development with Scaffold-ETH and The Graph. We explore how to write simple smart contracts, develop on a local development chain, run a local Graph Node that connects to that development chain, write a subgraph, deploy that subgraph, write a front-end and connect that front-end to the subgraph and the contracts.

In the realm of Web3, innovation transcends technology; it hinges on the development of vibrant, authentic communities.

AI can pose risks to individual autonomy, namely loss of control over personal data and erosion of individual agency and data integrity in the face of homogenizing algorithms. To make matters worse, deepfake technology is beginning to make it increasingly difficult for users to tell who’s real and who’s not.

We must enable users to own and control their digital personas independently of centralized authorities. This ensures autonomy in managing online presence and data sharing.

Integrating privacy-preserving technologies such as blockchain-based digital identities allows users to verify their personal attributes or transactions without disclosing underlying personal data. Educational initiatives that help users understand digital footprints, smart contracts, and data-sharing implications are fundamental to maintaining autonomy.

Users need to have a say as to how their data is utilized by AI algorithms. Blockhain-based data governance models empower users to have a say in the evolution of network protocols and policies, and Web3 digital identities provide users with more control over where their data is sent and who can view it.

We also need better standards for interoperability for interactions across blockchain networks and applications. This ensures users can navigate Web3 without being locked into specific platforms or ecosystems.

This approach is about starting a dialogue among technologists, policymakers, and users to shape an AI-powered internet that gives users control of their identity and upholds the rights and distinctiveness of every person. With roughly four million people using Web3 digital identities, we are seeing promising changes, but there is still much to be done.

This talk is meant to explain UTXO, it’s benefits and how it helps to scale Ethereum. Concepts such as state bloat, parallelization, merkle trees, access lists and predicate will be covered in order to show how UTXO based VMs can help to scale the ecosystem.

They tell me web3 is better. They say that we're taking back control of the internet. We're taking control of our digital stuff. WE control the memes now. That's great! Let me in! This is the place I want to be. But, why are you stalking my address on Etherscan? Why am I afraid when you see the Metamask icon on my phone? No, please don't look at those dodgy mints I aped into. Don't judge me for my defi-summer plays. What do you mean you don't trust my voting rationale? But is it safe to use mixers?

Web2 was plagued with predatory practices that arose from masses of data sitting in centralized systems, and while Web3 aims to circumvent that by removing the central point of trust, we see new problems arising. Transparency and verifiability are the drivers of healthy decentralized financial and governance systems, but are they necessary to facilitate an individual's daily movements online? Is there a way that users can have privacy? Beyond that, as systems become more abstract and complex, is it easy to use and maintain that privacy?

In this talk, we'll categorize some blockchain privacy problems, from the protocol level to the individual, and introduce recent cryptographic innovations that help to mitigate them. We'll show how they can be used build scalable decentralized applications for a variety of purposes, including preventing front-running attacks on DeFi platforms, end-to-end encryption for decentralized messaging and social networks, cross-chain bridges, as well as advanced cryptographic primitives such as witness encryption and one-time programs that previously could only be built from secure hardware or using a trusted third party.

Providing a compass for newbies and veterans to the waters of on-chain trading. This presentation explores recent advancements to AMM design, highlighting their potential for serving LP providers and traders alike.

The current blockchains do not provide any security guarantees to the smart contracts and their uses. In the spirit of decentralization and censorship resistance, they follow the paradigm of including valid transactions in blocks without any further scrutiny. Rollups are a special kind of blockchains whose primary purpose is to scale the transaction throughput. Many of the existing rollups operate through a centrally operated sequencing protocol. In paper, we introduce the Sequencer Level Security (SLS) protocol, an enhancement to the sequencing protocols based on the OP stack and Optimism Bedrock. This pioneering contribution explores the concept of the sequencer’s capability to identify and temporarily quarantine malicious transactions instead of including them in blocks immediately. We describe the mechanics of the protocol for both the transactions submitted to the rollup mempool, as well as transactions deposited from L1. We comment on topics such as trust and decentralization, and consider the security impact on the protocol itself. We consider implementation details using the OP stack and Geth. The SLS protocol described can be easily generalized to settings other than the OP stack, and can be used for purposes other than security.

In our talk, "Bridging EVM and Non-EVM Assets: A Practical Approach", we explore how to bridge blockchain assets in an effective and practical way, focusing on the Neo Blockchain's latest version, Neo N3 (Non-EVM), and its new EVM-compatible chain, Neo X.

We present the design and implementation of the native bridge between Neo N3 and Neo X, serving as the primary interoperability layer of assets between these distinct technologies. The term 'native bridge' highlights the embedding of contracts and functionalities at Neo X genesis as a precompile, integrating them as essential parts of the network's foundation.

In our development journey several potential solutions were considered, each with their own set of advantages and limitations. This includes zero-knowledge technologies, optimistic rollups with challenges, and state root proofs (MPT). While emulating geth in the NeoVM is challenging due to high execution costs, Neo X was not designed as a rollup, but as a sidechain.

Ultimately, we opted for a trusted bridge solution implementing the concept of an Ordered Binary Hash Chain data structure. This approach is not only cost-effective and of low complexity, but also maintains the validation of the historical sequence of bridging actions, providing a balance between efficiency and transparency.

The presentation concludes with a forward-looking perspective, touching on the current testnet state and the roadmap towards mainnet. Anticipated future enhancements are discussed, including the potential decentralization of bridge validators and relayers, as well as further features.

In 2023 we saw an explosion of new stablecoins and borrowing solutions (Curve, Prisma, Lybra, ...).

What are the different approaches?
What are the challenges of the approaches and how can they be overcome?
Which factors will determine the ones that will last?

We will explore the recent onslaught of rounding issue exploits haunting the world of DeFi. From relatively smal and unknown Compound v2 fork exploits to Balancer pools with $1 Billion + in TVL, nobody is immune from rounding issues.
The talk will define the origins of the issue, its nuances, significant instances of it, and what we can try to do to protect our protocols.

Explore how institutional investors are revolutionizing their asset management strategies. Experienced asset managers are crafting the optimal formula, seamlessly unlocking the vast opportunities within DeFi, all while maintaining the straightforward simplicity synonymous with traditional finance (TradFi).

We study shared sequencing for different chains from an economic angle. We introduce a minimal non-trivial model that captures cross-domain arbitrageurs' behavior and compare the performance of shared sequencing to that of separate sequencing. While shared sequencing dominates separate sequencing trivially in the sense that it makes it more likely that cross-chain arbitrage opportunities are realized, the investment and revenue comparison is more subtle: In the simple latency competition induced by First Come First Serve ordering, shared sequencing creates more wasteful latency competition compared to separate sequencing. For bidding-based sequencing, the most surprising insight is that the revenue of shared sequencing is not always higher than that of separate sequencing and depends on the transaction ordering rule applied and the arbitrage value potentially realized.

Threshold cryptography enables a group of nodes to jointly perform cryptographic computations using a key that is shared among the nodes. In most settings, for n nodes and a threshold t, any subgroup of at least t nodes will be able to perform the intended computation whereas any subgroup of less than t nodes will not.

After threshold cryptography had been primarily a field of academic research for many years, it recently gained traction in practice due to the advent of blockchains and decentralized ledger technologies more generally, whose settings are well aligned with the distributed nature of threshold cryptosystems. Nevertheless, there is still a significant gap between the academic results and the implementation of threshold cryptography for mission-critical applications.

In this talk, I will provide a gentle introduction to the topic and explain how threshold cryptography can be deployed in a highly reliable way in a blockchain network. I will also describe several use cases that make use of threshold cryptography to bridge between different blockchain networks.

Typically, a swap is instant and discrete. In blockchains where transactions are not deterministic, such swaps are often subject to a class of game-theoretical attacks known as maximal extractable value (MEV). Even when this attack is mitigated or minimized, a trader may still prefer a more "boring" way of trading due to the notorious difficulties in managing price volatility and risks as an individual trader.

The fundamental solution to this problem is introducing the concept of continuous-time swaps, where trading happens through a function of time.

In this talk, we will compare several designs of continuous-time swaps and explain why it is feasible and crucial to demonstrate the unique features that Blockchain-based financial systems bring.

Decentralized voting is a key element of blockchain governance, yet participation in this process on Ethereum is significantly hindered by high gas fees. Alternative solutions like Snapshot have emerged, offering an off-chain voting mechanism to sidestep these fees. However, such solutions introduce considerable challenges, particularly the lack of direct enforceability of votes on the blockchain. This discrepancy can lead to misalignments between governance decisions made off-chain and their actual implementation on-chain.

This workshop explores an ERC-20 based, 100% on-chain voting system enabled by leveraging the Internet Computer (IC) blockchain. This innovative multi-chain setup integrates the Ethereum and IC blockchains, presenting a novel approach to blockchain governance. Moreover, the presented set-up is designed to be adaptable for broader applications in multi-chain governance, facilitating decision-making across different blockchain networks.

New Use Cases & Benefits Derived from Transforming Subgraphs into Read-Oriented Rollups:

Subgraph code is turing-complete and has access to on- and off-chain data. It's execution is fairly deterministic and economically verified through Indexer stake. This creates interesting use-cases where more of data access and processing can be moved off-chain into subgraphs and the results can be brought back with oracles on-chain. Decentralised weather insurance is one example.

In this talk, I walk through the primitives and explain how they work together.

I will present a new class of oracle-free DeFi protocols, that remove the need for oracles through mechanism design and incentives.

The future of blockchain tech rests on rollups; highly performant fully-serviced chains custom-fitted for various use cases. As Ethereum's scaling tech, rollups will crush congestion and unlock near-zero gas fee's enabling a new breed of zero-gas chains. This will be ultimately the driving force behind a new generation of zero-gas dApps, attracting new users, and facilitating widespread adoption of blockchain technology.

This talk will deep-dive into various flavors of scaling technologies like alternative DAs and underlying infrastructure requirements to create truly gasless onchain user experiences like gasless NFTS, Games and finance.

Storage protocols such as Filecoin and Arweave are developing native VMs enabling decentralized applications to access and compute massive amounts of data, unlocking new capabilities for Web3.

Overview of Ethereum staking trends, market structure and impact of institutional inflows. Proposal to encourage institutional allocators to rely on decentralized protocols over centralized counterparties.

What if I told you that building and hosting a dApp entirely on-chain in just a few minutes is possible?

Join me in this hands-on workshop to explore Juno, an open-source Blockchain-as-a-Service solution based on ICP that simplifies Web3 development.

We'll cover integrating authentication, persisting data, uploading files to storage, and adding analytics. Plus, we'll dive into serverless functions, vastly expanding your project's capabilities.

Whether you're a 10x engineer or new to coding, this workshop will offer insights into building on the decentralized web with ease.

With a world of multiple layer-1 and layer-2 chains, we need to go beyond redeploying the same contract to various chains. Duplicating protocols to various chains fragments liquidity and stops the innovation. We need to cross the layer-2 chasm and design protocols with inter chain composability in mind.

Introducing liquid and publicly accessible governance tokens early on in the life cycle in the project forces entrepreneurs to rethink the rules. In this talk we will evaluate the challenges introduced and the solutions that have been tested, as well as some prospective opportunities.

Defi apps need to price collateral. Spot prices approximate the value ignoring slippage and fees. Redstone proposes a multi-dimensional curve where the price is a function of the quantity of assets to improve risk management and capital utilization.

This talk presents the "DAO Radar Switzerland" report, the first comprehensive analysis of Switzerland's DAO ecosystem, supported by InnoSuisse, CV Labs, and ZHAW, which focuses on DAOs with Swiss legal structures and will be published in March 2023. It explores the challenges and opportunities for DAOs and their ecosystem partners across legal, tax, and technological dimensions. Targeting founders, investors, policymakers, and researchers, the report aims to deepen understanding and aid decision-making in the DAO ecosystem by generating key insights and directions for the advancement of Swiss DAOs, enriching the conversation around decentralized organizations.

The goal of this workshop is to give an introduction on Ethereum as a protocol. The workshop will be structured in 4 mini sessions: fundamentals, execution layer, consensus layer and R&D roadmap. I will start from first principles and make sure that anyone curious about the inner workings of Ethereum can follow and get the core concepts and inspiration to go deeper on specific topics. The workshop is intended to be interactive and there will be time for Q&A rounds.

Learn how to use React Native to build true cross-platform experiences (iOS, Android and Web) for your decentralized apps, from a single codebase. Share code, features and maintain design consistency while opening your product for new user markets.

Since the launch of the first DAO framework few improvements have been made technologically. The first generation were true protocol DAOs, think Maker, Compound, Lido and have been replaced with trusted offchain signalling organisations. Why? Gas costs and the lack of flexibility. Governance Modularity will be an unlock for the next generation of DAOs, where they don't need to make trusted tradeoffs to achieve their goals.

Over time, non-fungible tokens have transcended their initial buzz, unveiling their potential as robust tools for certifying authenticity and quality. This presentation seeks to explore NFTs' role beyond mere collectibles, focusing on their utility in certifying quality for both digital and physical assets in a way that resonates with consumers unfamiliar with blockchain technology.

By examining case studies and user-friendly applications, the aim is to demystify the technology for the everyday consumer, emphasizing NFTs in the phygital realm and the creation of digital product passports. Through this lens, the focus we will put on the importance of intuitive user experiences, the integration of NFTs with existing consumer habits, and the potential for NFTs to revolutionize product certification and consumer trust.

Non-Fungible Tokens (NFTs), a new entrant in the digital asset space, have garnered significant attention and inspired a community of passionate collectors and investors. However, NFT markets are vulnerable to fraudulent activities, particularly wash trading, which involves deceptive market activity and inflated sales prices. In this paper, we propose a novel algorithm to detect wash trading by leveraging the feature that NFT transactions on the blockchain constitute a chain of ownership. Through extensive analysis, we examine the evolution of wash trading patterns across the NFT market and pinpoint traders who consistently influence prices. Furthermore, our algorithm detects multilayer wash trading and exposes resulting price manipulation. By improving our understanding of the risks of the NFT market, our approach contributes to creating a safer, more transparent, and fairer environment for all participants.

This paper explores the transformative potential of Decentralized Autonomous Organizations (DAOs) as a catalyst for sustainable community development amid the prevailing era of centralization. It scrutinizes the principles of Decentralized Coordination while examining their ability to empower communities, foster inclusivity, and redefine governance structures. Through case studies and analysis, it explains how DAOs offer a paradigm shift, providing a decentralized alternative that resonates with the ethos of sustainability and community-driven progress. The insights presented contribute to a broader understanding of DAOs' role in shaping a more equitable and sustainable future.

Decentralized autonomous organizations are a fascinating organizational structure found everywhere in the Ethereum ecosystem. However, designing a successful DAO is difficult and involves many aspects such as organizational design, legal aspects, and a roadmap to decentralization. In this workshop, the Swiss industry association DAO Suisse is going to give a crash-course on how to design a successful DAO covering these aspects. We will give short inputs on the different topics and then open for a discussion to cover the challenges faced by the workshop participants and learn together how to approach them. The workshop serves as a starting point to better understand the design of DAOs and offers assistance in how to set up DAOs for practitioners.

Smart contract development often involves using different tools serving different purposes like testing, analysis, deployment, or vulnerability scanning. We introduce a comprehensive open-source Python toolkit tailored for everyday Solidity development. The Wake tool is presented with simplistic real-world examples compared with other open-source options.

This talk covers the following scenarios:
- unit testing and cross-chain testing,
- fuzzing,
- vulnerability and code quality issue scanning,
- work with the editor (including enhancement with custom detectors and visualizations).

Debugging smart contracts on Ethereum faces challenges due to the disparity between high-level languages and the Ethereum Virtual Machine (EVM). The absence of a standardised debugging format hinders the correlation between low-level system behaviour and the original code intent, impacting transparency and trust. We want to showcase a tailored debugging data format to be introduced to improve smart contract development. Ethdebug format could act as a bridge between EVM execution and human-readable code, facilitating precise translation of machine code.

The impracticality of reasoning about machine code output without a standardised mechanism is clear, impacting smart contract software quality. Ethdebug not only enables machine-to-human translation but also accommodates unique architectural decisions responding to EVM constraints. Its adoption could significantly lower barriers for smart contract development, enhance software quality, and preserve trust within the Ethereum community by establishing a transparent connection between code execution and developer intent.

Visual Studio Code extensions improve the smart contract development process in productivity, but it can also be an early stage security tool. Every Solidity extension has different features; from syntax highlighting, code lens, or call graphs to sophisticated static analysis and vulnerability detections. Let’s compare the strengths and weaknesses of the most popular extensions and find the ultimate combo for code security.

The cloud computing market faces challenges such as opaque pricing, a lack of confidentiality, and monopolistic control. Despite these issues, cloud computing is widely adopted, with about 90% of organizations relying on it, increasingly moving from on-premise solutions to cloud services. The discussion touches upon the limitations of Moore's Law in the modern context. Initially predicting the exponential increase in computing power over time, Moore's Law now confronts physical limitations like the speed of light and quantum precision. As a result, the focus has shifted from mere performance enhancement to energy efficiency, encapsulated in the Performance-Per-Watt metric.

This talk highlights the critical role of mobile chips in transforming the cloud computing landscape, where novel ARM64-based Systems-on-a-Chip (SoCs) are highlighted for their specialized cores and high energy efficiency, offering a more cost-effective solution than traditional server hardware. One example of driving forward this revolution is Acurast, pioneering the use of a decentralized network of mobile devices. Further, this talk outlines an architecture and mechanisms in a way forward to operate a fully decentralized and serverless cloud, all orchestrated by a blockchain consensus mechanism.

This lecture will cover the background maths needed when either developing zero knowledge proof applications, or working at the protocol level

Gathering stakers, operators and integrators on a fully transparent and on-chain staking platform to unlock new use-cases in staking, such as pooled staking, custom liquid staking (and re-staking) tokens, and NFT staking.

Web3 infra allows more and more applications to be built that have a substantial amount of their transactions on-chain. This shift requires more and more automation and coordination to provide truly good UX for the users. However, most projects use centralized web2 infrastructure to do this. With implications on complexity, cost and security. In this keynote we explore those topics and how cryptography (especially threshold cryptography) might help us solve some of them.

The keynote will have the following components:
- How is plumbing built in web3 today?
- Why is it relying so much on web2?
- Why is this a hard problem?
- How can Threshold cryptography help solve this?
- How can this be implemented in real life?

During the presentation, I would like to share practical insights and tips from our in-depth research conducted with the support of a grant from the Uniswap Foundation. It will be a journey into the heart of Uniswap V4's architecture, where we'll unravel the complexities and innovations of its hooks mechanism. Based on examples, I will discuss the threats specific to most popular hook use cases. This talk promises to be a treasure trove of insights for anyone keen on mastering Uniswap V4 hooks and fortifying their security.

Key Takeaways for audience:

• A richer understanding of Uniswap V4's innovative architecture.
• Practical strategies for developing and securing hooks.
• Insights from research supported by the Uniswap Foundation Grant.
• Further materials they can use to increase the security of their hooks.

In the rapidly evolving world of blockchain technology, the mempool often remains an underexplored territory. With my projects, RollaMate.io, Acid Chains and PATIO station, I've delved deep into this realm, seeking to harness its expansive capabilities to push the boundaries of the Ethereum Mainnet and other EVM-based chains.

Growing Web3 (Blockchain-based applications) beyond the hyped and into practical use cases, seeing the developments of the different ecosystems in Switzerland, Europe, and worldwide.

In the evolving Web3 landscape, understanding and retaining talented developers is more crucial than ever. "Why Developers Drift Away: Strategies and Challenges in the Web3 Ecosystem" explores the diverse motivations of developers, proposing strategies to synchronise these with the growing demands of the Web3 ecosystems. The significance of ongoing education and varied activities is highlighted, underscoring their role in not just enhancing skills but also in cultivating community and engagement.

The talk further examines why the conventional tactic of restricting developers to a single platform falls short in the Web3 realm, which is characterised by its open and decentralised nature. Our focus shifts to fostering a developer community by offering an enhanced developer experience tailored to individual developer preferences and goals. We will investigate various hurdles encountered in this effort, providing insights on tackling them individually, while recognising the absence of a universal solution.

The workshop introduces a unique way of enhancing LSP (Language Server Protocol) compatible editors with custom text and visual decorations. The presented concept opens new possibilities for Solidity source code analysis, replacing labor-intensive manual tasks with simple scripts in Python.

Participants of the workshop will learn how to effectively highlight specific segments of Solidity code and visualize critical information derived from source code analysis. Moreover, attendees will understand the basics of Solidity Abstract Syntax Trees, an internal representation of Solidity source code.

Given the dynamic nature of the IDE enhancements, the workshop holds particular value for auditors and reviewers who are tasked with ensuring code quality and security, as well as developers seeking to streamline their coding process.

My presentation will be about elliptic curves, finite fields, group operations and scalar multiplications. I will explain why we use these operations when it comes to calculation of the ZK proofs. Also, If someone wants to be a Zero Knowledge engineer, they will see how deep they need to know about the mathematics part of the coding.

Design is often brought to the table for its need, and the user experience of web3 could be better and block mass adoption. But is it really a blocker? In this Talk, I will answer this question and share valuable hints and tips for overcoming this challenge.

Most software developers in the blockchain space publish their source code on GitHub and release it under an open source license. However, in an effort to protect their intellectual property rights, an increasing number of projects have decided to move away from the (pure) open source model. This presentation will explain how Web2 and Web3 companies differ when it comes to IP protection and take a look at different software licensing practices that are used by industry leaders. The presentation will also look at the vampire attacks and assess them from a legal perspective.

What is cypherpunk and how close are we to the cypherpunk value that shaped the early crypto days? This talk will analyse how early crypto values are reflected today, and how the Swarm Network makes those values actual again

In the rapidly evolving landscape of DeFi, one of the pressing challenges is the rigidness of current lending models, which predominantly rely on overcollateralization. This approach, while secure, limits flexibility and accessibility for a variety of participants.

This presentation explores the emergence of innovative lending solutions that aim to address these challenges by introducing undercollateralized lending mechanisms. Unlike the traditional models seen in well-known platforms, the new approaches allow for more diverse asset borrowing and lending, extending beyond the common stablecoins and WETH, and incorporate partial collateral withdrawals.
By integrating a trust element through rigorous KYC processes and market-driven terms, these novel mechanisms offer a secure and permissioned lending environment, shifting the paradigm from the principle of minimal trust.

This not only provides market makers and DeFi protocols with medium-term capital without the need to dilute their native tokens but also enhances asset liquidity, flexibility, and transparency within the DeFi ecosystem.

The discussion will cover the technical foundations of these innovative lending models, their implications for market participants, and the potential for fostering a more inclusive and stable DeFi ecosystem. The focus will be on understanding how undercollateralized credit facilities can reshape DeFi lending, highlighting the broader implications for growth and stability in the DeFi space.

How to build an intent machine for Ethereum

Liquidity pools are essential for the functioning of decentralized finance. Nevertheless, the legal issues they raise have found little attention in legal scholarship. In our talk, we will explain the way liquidity is provided in decentralized finance, as opposed to centralized finance, and introduces the relevant stakeholders (i.e., DEX operators, liquidity providers, and traders). Then, we will explain the legal relationships between such stakeholders from a contract law perspective. Further, we will discuss the options of users to seek compensation in case they incur damage in connection with the use of decentralized finance platforms. Finally, we will talk about the limitations of the existing legal framework and the need for legislative action.

Fuzzing is a powerful testing technique that uses random inputs to a tested program. It can uncover edge cases developers overlook and detect bugs often missed by manual review. However, many web3 developers underestimate the need for fuzz tests and deploy their projects without them. This workshop is created to show how simple it may be to create and run fuzz tests for your projects.

For our workshop, we will use the Solidity code of a smart contract optimized with Yul and containing unobvious errors. First, we will compare different fuzzing approaches and tools focusing on guided fuzzing. Next, we will create a fuzz test for the code from scratch that we will run locally. Finally, we will evaluate the outputs and discuss how fuzzing can be used for bigger projects.

At the workshop, the attendees will gain the knowledge and skills necessary to integrate fuzz tests into their development workflows and add another layer of security to their projects. We aim to make web3 safer and welcome all developers and security researchers to join us in this workshop.

In an era where the convergence of traditional finance and blockchain technology is inevitable, understanding the mechanics of how conventional financial concepts are translated into the decentralized environment is crucial. This speech delves into the intricate world of blockchain technology, with a focus on Ethereum, a leading platform for decentralized applications. Specifically, it highlights the innovative Asymetrix protocol, showcasing its pivotal role in integrating traditional financial principles into the blockchain space.

Decentralized science is a movement that seeks to regenerate scientific work through the use of Blockchain tools. It is a model that allows direct interaction with researchers and DAOs. In Mexico and Latin America, the percentage of resources directed to science is less than one percent and this means that research is of low quality and has no commercialization potential. The intellectual property often belongs to the institution that grants the financing and this centralized model limits access to the data and removes the intellectual property from the researcher who created the project. The objective of this talk is to explain the general panorama of decentralized science and how its application in Latin American countries would boost their economy and scientific work

Hackathons can potentially promote youth digital empowerment in Africa. But their design tends to follow the European and North American perspectives. Research has shown the key role of cultural aspects such as temporal awareness and temporal structure in fostering innovation during hackathons. Our project questions the status quo and seeks to investigate the approaches to designing culture-sensitive hackathons for empowering African youth within the Ethereum ecosystem.
The results will contribute to the practical design of Ethereum hackathons and to the academic conversation around temporality and innovation.

Since the 1st of February 2021 Switzerland has a DLT law that allows issuing ledger-based securities. Shares of private companies issued that way bear significant advantages over other forms of shares e.g. uncertificated securities. A transfer of such security tokens is a legally solid transaction and eliminates the need of a signed assignment document. Aktionariat has built a software solution around this law that allows private companies to create a market for their shares based solely on smart contracts, without intermediaries.

Building a Web Application that will be able to interact with a hardware device and enhance security on your interactions with the ecosystem.

Novel architecture for digital assets and CBDCs trading using Layer-2 and Layer-3 blockchains. Even with liquidity fragmentation, a multi-layer and multi-AMM setup is more cost-efficient than a single AMM on layer-1 blockchain.

web3.js is an open-source library created by Ethereum founders in 2015 with more ~2 million of downloads per month.
Web3.js helps developers to interact with any EVM blockchain using Type/JavaScript, with the new v4 release, developers can create plugins with several functionalities, which can improve the developer experience and make things easier for developers to interact with any web3 project.

Stablecoins play a crucial role in today's blockchains, bringing liquidity and fostering user adoption, as seen in both L1 and L2. It is therefore extremely important to understand their future development. So far, we have seen competition between centralized and decentralized solutions, but the introduction of new assets, "real world assets" and CBDCs, could reshape this landscape. We will discuss recent product innovations in this area and, based on a competitive economics approach, discuss possible future outcomes. Specifically, this talk will explore three key areas: 1) the current landscape of value transfer using low-volatility assets and the motivations behind such transactions; 2) emerging methods and motivations for value transfer on Ethereum; and 3) an examination of future value transfer mechanisms through the lens of competition economics, considering the evolving roles of stablecoins, CBDCs, and real-world assets.

As the worlds first digital asset bank, Sygnum has championed the crucial role that tradfi institutions play in the growth and adoption of crypto. CeDeFi represents the convergence of traditional financial systems with decentralized finance, bringing the institutional safeguards of Cefi to the power and opportunity of Defi. In this talk we highlight different examples of this convergence, where it has been successful, challenges we faced, and opportunities for investors, developers, and enthusiasts alike.

MakerDAO has proven the concept that capital generated on-chain can be deployed into RWAs (real world assets) to generate yield, maintaining protocol profitability when DeFi usage drops. This was a watershed moment for DeFi, providing a blueprint for other protocols to follow; however, critical on-chain infrastructure still needs to be developed for this process to scale and DeFi with it. What is the missing element, and how could it enable a new wave of on-chain customers?

Blockchain scaling and interoperability are the last major barriers standing in the way of fulfilling Web3's promise and driving widespread adoption across a full range of use cases. This speech summarizes the enormous recent progress towards this goal and gives attendees a thorough understanding of the technological developments that will underpin data availability, aggregation, and shared security. In particular, it will show how a modular approach is the key to unlocking the potential of blockchain, Web3, and decentralization.

Designing a decentralized autonomous organization (DAO) is an intricate task and the literature and practice have called for more research on the design of DAOs. In this talk, we are going to present a DAO design framework that can be used in practice to set up a DAO. We developed the framework within a research project at Zurich University of Applied Sciences. The developed framework is based on DAO literature and organizational theory and evaluated with domain experts and potential users. The proposed design framework identifies three constituent elements (purpose, legislation, business case) influencing the organizational structure– and five structural elements (organizational bodies, decision-making, token, treasury, communication) that need to be actively designed when setting up a DAO. The talk serves as a starting point to better understand DAO organizational structure and offers assistance in how to set up DAOs for practitioners.

This talk will showcase the intersection of threshold cryptography and passkeys and how they can be used to create a new generation of browser-based wallets. These wallets have the ease of use of custodial wallets, but with reduced trust assumptions.

I will use the example of the Oisy Wallet (https://oisy.com/). An open source (https://github.com/dfinity/oisy-wallet) cross-chain wallet hosted on the Internet Computer that supports the novel concept of network custody. Oisy is developed by the Dfinity foundation.

Less than 18% of all that we produce and consume is currently being recycled, despite the potential for recycling more than 90% of these materials. In addition to ending waste, transitioning to a circular economy can deliver 85% of the carbon emissions reductions needed to stay below the 2ºC limit.

Carrot Fndn built a protocol enabling tracking of waste (mass ID) a conversion into carbon credits tokens, sold to companies, with the proceeds being distributed via smart contract to all participants contributing to the objective of a more circular economy.

Account abstraction is a confusing world from an ERC perspective: we have tens of ERCs - how do they relate with each other? Do they compete technologically? Do they compete for attention? Are ERC-4337 and ERC-3074 competing with each other? We'll split them into a few categories and look at them separately: native AA ERCs, non-native AA ERCs, signature ERCs, EOA conversion ERCs.

In this workshop, you'll learn the basics of the Internet Computer Protocol and its superpowers. Based on this knowledge, you'll learn how to hook into Ethereum smart contracts from ICP to leverage ICP as a coprocessor or as an orchestrator between multiple EVM chains.

Open-source developers face critical economic challenges. They lack a dedicated business model and are faced with a tough choice: They can either adhere to the community, open-source, and free software principles, but that often results in a lack of funding and resources, or they can compromise on those values by adopting a more traditional company model.
With blockchain, we can finally have the best of both worlds: a community-driven ethos and commercial success. Let’s explore how we can fulfill all stakeholders' needs and attract investors by leveraging blockchain, tokenomics, and DAO!

This talk will cover the balance of ownership, network abstraction, and the significant strides and challenges in the journey of making web3 invisible to users. I'll also examine the role of passkeys in revolutionizing user authentication, marking a pivotal step forward in the quest for a more integrated and accessible web3 ecosystem.

This presentation explores Ethereum's journey towards sustainability. We'll start by discussing how to measure the environmental impact of blockchains. Then, we'll dive into key milestones in Ethereum's Green Evolution: its beginnings with Proof of Work (PoW), the groundbreaking switch to Proof of Stake (PoS) with 'The Merge', and the recent Dencun upgrade. We'll analyze the extent to which the Dencun upgrade reduces emissions per transaction and explore what the future holds for an even greener Ethereum.

Last year we introduced FCL, the fastest P256 implementation of the ecosystem. We present our new breakthrough with 2 additional implementations, one targeting onchain SGX, the other targetting Passkeys

The focus of the panel will be to unravel the intricate landscape of Ethereum Virtual Machine (EVM) implementation differences between Layer 1 (L1) and Layer 2 (L2) networks, shedding light on the challenges arising from the diverse and non-standardised nature of L2 ecosystems. We'll be delving into the nuances of EVM compatibility versus EVM equivalence and explore the assumptions and challenges that developers face in this evolving space, especially with L2s emerging as a transformative force.

The multichain environment brings both differences and complexities, and the panellists will try to address the dynamic terrain of L2 technologies - from diverging pathways to potential convergence. The discussion will extend beyond technical considerations, exploring the profound implications for Web3 infrastructure and development toolkits.

Regulatory landscape and hurdles within the decentralized finance sector in Switzerland and Liechtenstein, with a particular focus on the implications of the Markets in Crypto-Assets (MiCA) regulation. On-chain zkKYC infrastructure solution for DeFi (https://albus.finance)

Account abstraction offers numerous opportunities to streamline on-chain user interactions, yet its adoption remains limited, primarily due to its complexity. Gas fees are a significant concern for user experience on-chain, whether one is an existing participant or a newcomer. In this presentation, I will outline a comprehensive explanation to completely abstract gas fees for all users, utilizing zkSync's built-in native account abstraction. I will be able to show some uses cases and how the zkSync space is evolving into that direction.

We would like to present our latest paper on an empirical study of Idena protocol (idena.io). The paper titled “Compressed to 0: The Silent Strings of Proof-of-Personhood" is co-authored by Puja Ohlhaver, me, the founder of Idena, and Paula Berman.

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4749892

The paper highlights the flaws of Proof-of-Personhood, which prompted the Idena protocol to pivot towards "sublinear identity staking”. The findings will undoubtedly serve as the foundation for the next generation protocols proposing Sybil-resistant and collusion-resistant forms of consensus.

Since the emergence of concepts like network state, coordi-nation, we have witnessed a surge in pop-up communal living within the crypto community. Drawing from our experiences from the Zuzalu community, we explore the dynamics of digital tribalism in crypto ecosystem and the profound impact it has on society and individuals. From fostering a sense of belonging to embracing decentralized governance structures, we uncover the valuable insights gained from living in the web3 era. Furthermore, we discuss our ambitious plans to establish a presence in Switzerland this year, highlighting existing democratic practices in Swiss organizations and businesses.

Privacy in a distributed ledger is a hard thing to do. Not only it needs to be redesigned, but it also involves big changes in the concept of wallet.

Instead of holding keys and signing, a wallet will actually be a powerful executor, a database of UTXOs, a server.

In this talk we will go over Aztec’s approach to private execution, focusing on its privacy workhorse, the PXE.

Our mission is to develop the essential missing component in DeFi: a fixed income protocol. In traditional financial markets, Money Markets, Foreign Exchange Markets, and Fixed Income Markets collectively constitute the entire debt financial market. However, in DeFi, only Money Markets and Foreign Exchange Markets are currently functioning, as fixed income represents the most complex financial instrument. The intricacies of the term structure of interest rates make it unsuitable for automated market makers and peer-to-pool mechanisms, which are widely used in existing DeFi protocols. By addressing this challenge, we aim to complete the DeFi ecosystem and unlock new opportunities in the space.
Fixed income serves as a crucial foundation in traditional financial markets and should hold an equally important role in DeFi. The absence of fixed-income markets in DeFi hinders the accurate pricing of financial products that extend beyond the present day. By establishing fixed-income markets within the DeFi ecosystem, we can facilitate efficient borrowing and lending activities, develop forward and term futures markets, and enable seamless trading and hedging of real-world assets. Currently, real-world assets are limited to serving as collateral. If we do not develop fixed-income markets, DeFi's progress may stagnate, remaining at the same level it has been since 2020.
Our goal is to establish interest rate benchmarks for major stablecoins (USDC, USDT, and DAI), as well as ETH and wBTC. We aspire to become the go-to destination for people seeking to trade, hedge, or price interest rate products within the DeFi ecosystem.

For dApps that rely on oracles, any update to a data feed, or the lack thereof, can create opportunities for OEV such as frontrunning, arbitrage and liquidations. There are numerous solutions out there that allow you to combat the negative externalities of MEV through OFAs like e.g. MEVBlocker or Flashbots MEV-Share. In this presentation i'd like to showcase why these generalized OFAs aren't viable for oracles and how specialized OFAs for oracle transactions could be better suited to combat OEV.

A billion people in the world lack legal identification. Among these people, there are many exiles, stateless, and refugees that have had their identification tampered with or erased by malicious or incompetent state actors. Sadly, these people already started to be hurt by the technology that has potential to improve their lives. Much has to do with how digitalisation and blockchain developers are better connected to state actors that cause these problems rather than to communities that are affected.

Nearly every web3 transaction relies on infrastructure provided by closed-source, centralized infrastructure. They get full access to a startling array of personal data, and you simply have to trust them not to misuse it. We’ve come to accept this, but it doesn’t have to be this way! This workshop will show you just how serious the privacy issue is, and how little effort is needed to modify your wallet to use the same providers, only privately.

In recent years, SNARKs have shown great promise as a tool for building trustless bridges to connect the heterogeneous ecosystem of blockchains. Unfortunately, the parameters for many of the widely used blockchains are incongruous with the conventional SNARKs, which results in unsatisfactory performance. This bottleneck necessitates new proof systems tailored for efficiency in these environments.

The primary focus of this paper is on succinct bridges from Cosmos to Ethereum, which largely boils down to efficient proofs of multiple Ed25519 signatures. But these techniques can be ported to settings that require succinct proofs of multiple secp256k1 or BLS12-381 signatures.

We explore the schemes deVirgo and zkTree, which exploit the parallelization of proof generation and the subsequent aggregation of proofs. We also describe Panther Protocol's new scheme, which uses the field-agnostic SNARK to circumvent the huge overhead of non-native field arithmetic arising from Ed25519 scalar multiplications in the arithmetic circuit.

Our benchmarks indicate that it is crucial to sidestep non-native arithmetic to the extent that it is possible. The need for EVM compatibility makes it impossible to avoid non-native arithmetic. We also found that multiple proof systems need to be securely amalgamated. The schemes customized for Ed25519 scalar multiplications are different from those well-suited for SHA-512 hashes to maximize the efficiency of a succinct bridging scheme.

TL;DR:

EIP-X proposes a solution to Ethereum's statelessness problem by integrating zero-knowledge proofs (ZKPs) into the light client framework. This enables validators to provide concise proof of their staking activities, reducing computational burdens and enabling efficient restaking at scale. By addressing the challenges of penalizing validators for invalid blocks, EIP-X enhances network security and scalability, promising a brighter future for Ethereum's ecosystem.

Encointer is a public blockchain platform for local community cryptocurrencies. Individuals can claim a universal basic income through issuance of fresh money. Money supply is kept in proportion to population size through the use of demurrage. Sybil attacks are prevented by regular, concurrent and randomized pseudonym key signing parties to obtain a proof-of-personhood.

Blockchains are complex systems deployed over the Internet, requiring much data to be exchanged among individual peers. Also, before deploying your system to the mainnet, developers deploy the versions in their local environments to assess blockchain properties such as TPS, required hardware resources, connection, and others. Such evaluations determine how your system scales with additional resources and more peers in the network. Regular updates might change these properties, requiring a robust evaluation methodology. Therefore, we introduce a possible solution for L1, L2, and others, e.g., TEE, deployments, to collect insights about the system under the test and possibly compare different systems. We call our approach METHODA and it should help blockchain core developers to assess their blockchain scalability and other properties.

The workshop is dedicated to unraveling the complexities of supervision in the rapidly evolving Decentralized Finance (DeFi) landscape. As DeFi reshapes the traditional financial ecosystem with its distributed and pseudonymous structure, it brings forth a new set of challenges in risk management and regulatory oversight. This workshop aims to delve into these challenges and explore who should bear the responsibility for ensuring safety of assets and maintaining systemic integrity.

The session will start with an overview of DeFi’s unique characteristics, emphasizing its decentralized nature and how it differs from traditional finance. We will then shift our focus to the inherent risks associated with DeFi, such as smart contract vulnerabilities, liquidity issues, and the absence of a centralized governing body. A critical part of our discussion will center around the concept of "Do Your Own Research" (DYOR), examining its practicality and limitations in the context of DeFi risk management.

Furthermore, the workshop will explore the roles that various entities, including governments, regulatory bodies, and the DeFi community itself, can play in supervision. Can a decentralized system be effectively regulated, and if so, how? Should the responsibility of safety lie solely on the users, or should external parties step in to provide oversight?

Participants are encouraged to bring their insights and experiences to what promises to be a lively discussion. The goal is not just to identify the challenges, but also to collaboratively propose innovative solutions and frameworks that could guide the future of DeFi supervision. Whether you're a DeFi enthusiast, a regulatory expert, or just curious about the future of finance, this workshop will provide valuable insights into one of the most pressing questions in the world of blockchain and cryptocurrencies.

Switzerland typically does not have a government-led industrial policy that favors specific industries. This is in contrast to other countries from the US to the UK and from Saudi Arabia to China who are strongly supporting and funding specific industries such as solar, battery technology or AI. Here are some recent examples:

• New UK GPB 100m fund for AI
• Saudi Arabia announced a USD 40bn push into AI
• The US with its Inflation Reduction Act IRA will hand out billions in subsidies to chip makers, AI companies and other high tech industries

At the same time the EU is pushing for new regulation from the EU AI Act to the EU Markets in Crypto-Assets Regulations act that will have a big impact on the Swiss ecosystem.

We will show how EIP-1153, despite introducing a useful primitive for Dapp developers, breaks some security assumptions made by Vyper and Solidity smart contracts, leading to reentrancy attacks. We will also discuss mitigations.

We would like to show what the next big narrative for the blockchain industry might look like. Introducing the concept of Decentralized Confidential Computing, in short DeCC (De Cee Cee) - a class of solutions providing decentralized confidential execution of arbitrary computations using one of the following technologies or a combination thereof: TEE (Trusted Execution Environments), FHE (Fully Homomorphic Encryption), MPC (Multi-Party computation) or ZK (Zero-Knowledge proofs). Along with Decentralized Physical Infrastructure Networks (DePIN) and Decentralized Finance (DeFi), DeCC will define the next important category of use cases across all public blockchain solutions.
Going deeper into specific use cases for DeCC, we are showcasing a lightweight trustless bridge running on Secret Network that offers the execution of encrypted payloads & fast execution times for all available EVM compatible blockchains.
We will also take a dive into the confidential computing constellation, which is a consortium of different confidential blockchains that use TEE, FHE, MPC & ZK technology.

In the rapidly evolving landscape of decentralized finance (DeFi) and Web3, the threat of Sybil attacks and fraudulent activities looms large, undermining trust and equity in digital ecosystems. This talk will explore innovative strategies and technologies designed to combat these challenges, emphasizing the critical role of community engagement and advanced analytics.

DeFi Roundtable: Bridging Degen Innovation and Institutional Integration
The DeFi Roundtable serves as a pivotal gathering of industry professionals, spanning researchers, companies, and investment funds, each bringing a wealth of expertise to the table.
