Such designs typically suffer from high delays when sending many messages to multiple recipients, which limits their scalability in decentralized collaborative apps. Rollercoaster reduces the time for delivering messages to all $m$ members of a group to $O(\log m)$, without modifying the underlying mix network. It leverages the existing anonymity set and can handle unreliable group members while maintaining the same asymptotic guarantees. | | | | -------- | -------- | | **Short bio:** Daniel Hugenroth is a computer security researcher and software engineer living in Cambridge, UK.

Regardless of its nature, MEV has had profound impacts on how protocol security is viewed through the lens of cryptoeconomics. In this talk, we provide a short introduction to MEV in the context of Ethereum, as well as current approaches to dealing with its opportunities and risks. | | | | -------- | :--------: | | **Short bio:** Barnabé Monnot is a research scientist at the Robust Incentives Group, a research team of the Ethereum Foundation dedicated to mechanism design and protocol security. | <div class="crop"> <img src="https://hedgedoc.net.in.tum.de/uploads/6864edd4-2f07-4664-9693-c49dde8d7129.png"> </div> | ## Burak Öz (TUM) **Talk Title:** A First Study of MEV on an Up-and-Coming Blockchain: Algorand **Abstract:** MEV has been extensively studied in the Ethereum ecosystem for the past couple of years due to the significant effect MEV has on different aspects of the network, such as incentives, consensus, and economics. However, MEV is not inherent to Ethereum; it exists in any blockchain protocol with similar properties. One of those blockchains is Algorand, which is a smart-contract-based blockchain that adopts a Byzantine-Fault Tolerant (BFT) based consensus mechanism combined with Pure-Proof-of-Stake. Unlike Ethereum, Algorand currently does not have a developed transaction fee mechanism, as available block space exceeds demand. Hence, it is sufficient for users to pay a minimal, fixed transaction fee to get included in the next block. Moreover, these fees are not shared with the block proposers but are stored in an account controlled by the Algorand Foundation. Thus, the proposers do not have a direct economic incentive for block building and are assumed to fill transactions into their blocks in the order they hear them (FCFS). These properties make it interesting to study MEV in Algorand as they considerably differentiate how MEV extraction can happen compared to Ethereum. In this work, we present our research plan for analytically and empirically analyzing and evaluating Algorand's MEV and DeFi ecosystem and share our first results. | | | | -------- | :--------: | | **Short bio:** Burak Öz is a Ph.D. candidate at the chair for Software Engineering of Business Information Systems (sebis) at the Technical University of Munich (TUM) since August 2021.

All recorded information is open and accessible by all. This makes carrying private computations on such platforms highly challenging. In particular, smart contracts cannot carry any secrets with them, hence very limited in their cryptographic abilities. In this talk I will discuss work showing how to armor smart contracts with such cryptographic capabilities, hence enabling a wide range of applications not possible today. Examples include more efficient and secure state proofs, simplified and more secure bridges, the ability for a smart contract running in one chain to produce transactions in another chain (e.g., running bitcoin smart contracts over Algorand), carrying private medical data within a smart contract (while controlling the data, using it selectively, and keeping it private), enforcing private contracts (e.g., a will) on-chain, and much more. | | | | -------- | :--------: | | **Short bio:** Hugo Krawczyk is a Principal Researcher at the Algorand Foundation where he leads the Algorand Centers of Excellence (ACE) program.

This necessitates a trusted log to establish a non-repudiable timeline of events. The unique properties of blockchain facilitate this by providing immutability and availability. For power asymmetric environments such as the workplace, permissionless blockchain is especially beneficial as no trusted third party is required. Yet, two issues remain: (1) If a central arbiter facilitates exchanges, they could manipulate the log. Therefore, we need to guarantee non-repudiable data exchange in a decentralized setting. (2) With data governed by the GDPR, blockchain's immutability and transparency become a liability. After a rightful request, individual's data need to be rectified or deleted. And only those with justified interest should be able to read the personal data stored in the blockchain. To solve these issues, we present Kovacs, a decentralized data exchange and usage logging system for inverse transparency built on blockchain. Its new-usage protocol ensures non-repudiation, and therefore accountability, for inverse transparency. Its one-time pseudonym generation algorithm guarantees unlinkability and enables proof of ownership, which allows data subjects to exercise their legal rights regarding their personal data. Importantly, it can be used with any blockchain software and is fully decentralized. | | | | -------- | :--------: | | **Short bio:** Valentin Zieglmeier is a research associate and doctoral candidate at the chair of Prof. Pretschner.

By an arbitrary design choice, Bitcoin and most Proof-of-Work (PoW) blockchains have a limited supply. Once block rewards vanish, only transaction fees will remain as an incentive for miners to partake in the verification process. In this paper, we analyse the impact that miners bargaining over block composition has on consensus in the absence of block rewards: in this situation, competing blocks at the same height may be more attractive to peers by including less transactions (i.e. sharing the mempool). The mining and acceptance of blocks can be modelled as an Ultimatum Game, where miners' strategies represent their fairness sentiment. Extending previous Literature, our study focuses on the effect of the transaction arrival rate on global consensus in the system and whether local consensus is formed under certain assumptions about the strategies of miners. We find that consensus is threatened when the supply of transactions is low and stable consensus only emerges when the amount of unconfirmed transactions remains sufficient. In addition, when miners are set with randomised strategies, it is more difficult for the system to achieve consensus. Our research suggests that transitioning from a block reward incentive to a transaction fee incentive may weaken and even destroy the consensus of PoW-based systems. | | | | -------- | :--------: | | **Short bio:** Professor Claudio J.

However, the problems of decentralization, security, and scalability have been an obstruction to the mainstream adoption of this technology. The innovative solution for this Blockchain Trilemma resulted in spinning up of new networks, each having their own capabilities and restrictions. And while each of these networks have their own functionality, their stand-alone applications would not allow users to utilise the power of the blockchain tech in its full-potential. This generated the need to interconnect these networks so users could choose the most suitable solution for their needs, collaborate between different ecosystems and create interoperable Dapps, which gives rise to cross-chain bridge technology. In this talk, we will be discussing about the state-of-security in the web3 space, the blockchain trilemma, how it leads us to the world of interoperability of blockchain networks and the measures we should take while interacting with the bridges. | | | | -------- | :--------: | | **Short bio:** Smriti Verma is a Blockchain Security Researcher and Smart-contract Auditor at OpenZeppelin.

Still, after more than 40 years of research, limitations on performance and scalability for practical systems remain. A large corpus of existing work improves on consensus complexity, performance and introduces a multitude of optimization techniques. The state-of-the-art is complex. In this talk we identify common building blocks, used by a plethora of BFT-SMR systems. We exemplarily analyze the networking layer in context of BFT-SMR and discuss challenges and optimization potential. | | | | -------- | :--------: | | **Short bio:** Richard von Seck received his Master's Degree in Informatics from Technical University of Munich in 2018.

In this talk, I’ll give you a short primer on how funds work, what VCs do and what to think about when pitching to one. Venture capital funds invest in startups and advise founders on strategy, network, and sometimes exercise control board membership. They are structured as partnerships with general and limited partners, and have a management fee and carried interest. A fund's portfolio defines its success, with power laws dominating returns. Startups should consider whether to raise venture capital based on their goals and needs. If yes, it’s helpful to understand what the processes usually looks like and what VCs look for. | | | | -------- | :--------: | | **Short bio:** Jonatan is a venture investor at inflection.xyz.

For example, the ecosystem erroneously presumes the existence of reputable issuers which manage signing keys, verify identity claims, and issue credentials. Recent innovations in the "Web 3.0" context proposed solutions for the bootstrapping issue which are based on TLS-oracles or issuer-agnostic private identity claims. In this talk, instead of focusing on the improvement of conceptual approaches of decentralized ecosystems, we consider how the existing authentication infrastructure around OAuth could be enhanced with innovative cryptographic techniques from the "Web 3.0" domain to achieve a verifiable and user-controlled notion of identity. | | | | -------- | :--------: | | **Short bio:** Jan Lauinger is a researcher and PhD student at the Technical University of Munich with a research focus on TLS-oracles, decentralized identity, decentralized access control and decentralized policy compliant computation.

Several countries have already implemented a CBDC, and many others are actively investigating or piloting one. What’s clear is that most of these systems run on their dedicated infrastructure, rather than on public and/or existing blockchains. This creates interoperability challenges, such as how to transact with CBDCs from existing smart contract ecosystems. This talk aims to provide an overview of how CBDCs can be designed to address these challenges, and to provide practical examples of how integration with existing systems could be achieved. | | | | -------- | :--------: | | **Short bio:** Lars is a CBDC Evangelist at Giesecke+Devrient with a particular interest in security, offline payments, and financial inclusion.
