Talk by Laura Ricci (University of Pisa) Abstract: Recent years have witnessed, especially in Europe, a shift aimed at bringing users back at the center of digital systems. This has driven innovation towards the affirmation of decentralized systems, in line with the Self Sovereign Identity paradigm. User control over the consumption and disclosure of their data is a key topic of such drive. Thi...

Talk by Markus Legner (Mysten Labs) Abstract: As globally distributed systems, blockchains fundamentally rely on an available network infrastructure. Unfortunately, today’s Internet is vulnerable to a large number of attacks that may render it unavailable. On the other hand, centralized solutions offered by companies like Cloudflare contradict the decentralization promise of blockchains. Ideall...

Talk by Bhargav Bhatt (Web3 Foundation) Abstract: We introduce “Random Sampling”, a novel technique for on-chain light-clients to efficiently follow the finality of a PoS blockchain. Essentially, our technique draws randomness (e.g. RANDAO in Ethereum) from the target chain to verify the signatures of only a small subset of validators subsampled from the source chain. We also analyse the securi...

Talk by Josef Gattermayer (Ackee Blockchain Security) Abstract: Solidity development and security tooling are still evolving, the first ecosystem has grown around tools such as Brownie, Slither, Echidna, or VS Studio Code extension Solidity Juan Blanco wrote in 2015 and has over 1,2 million installations. Thanks to those early adopters, the next waves of tooling could arrive, improving comfort,...

Talk of Filip Rezabek (Technical University of Munich) Abstract: To assess various topologies, configurations, and data traffic types in permissionless setups, we introduce METHODS. It aims to provide, among many others, repeatable, reproducible, and replicable distributed systems experiments with high precision and flexibility. METHOD is based on commercial off-the-shelf hardware and uses the ...

Talk by Jan Jan Lauinger (Technical University of Munich) Abstract: Modern privacy-enhancing technologies reach new forms of computation or data compliance, compression, and privacy according to a statement (e.g., private value of more than 100). However, beyond the statement expression, the description of secure computation circuits requires knowledge of security algorithms protecting private ...

Talk by Sheng-Nan Li (UZH Blockchain Center) Abstract: In this presentation, we emphasise three foundational pillars-honesty, fairness, and sustainability-essential for maintaining and reinforcing trust in Blockchains and other Decentralised Platforms. Each pillar is exemplified through a dedicated project, which are focus on monitoring, analysis, and modelling of user behaviour and protocol fu...

Talk by Felix Hoops (Technical University of Munich) Abstract: In the evolving digital identity landscape, the concept of Self-Sovereign Identity (SSI) has emerged as a paradigm shift, empowering individuals with the ownership and control of their personal information. In this talk, we will explore how Blockchain and SSI are interconnected. We then present a middleware architecture that leverag...

Talk by Fabian Stiehle (Technical University of Munich) Abstract: For the enactment of inter-organizational processes, blockchain can guarantee the enforcement of process rules and the integrity of execution traces. However, existing solutions come with downsides regarding throughput scalability, latency, and suboptimal tradeoffs between confidentiality and transparency. To address these issues...

Talk by Ognjen Maric (Dfinity Foundation) Abstract: Blockchain protocol stacks often assume networking primitives such as reliable broadcast. But these primitives are problematic in a Byzantine environment, as they either require unbounded buffering, or give up reliability. Both options open opportunities for DoS attacks and endanger the protocol liveness. In this talk, I’ll describe the messag...

Abstract: The work on the Digital Euro is going full steam ahead. In January, the European Central Bank has issued calls for applications for component providers, including for example offline payments and fraud & risk management. Meanwhile, the European Parliament is considering the legislation in committee. In this talk, I will give an update about the current state and developments to be exp...

Talk by Jeffrey Burdges (Web3 Foundation) Abstract: Anonymized ring VRFs are ring signatures that prove correct evaluation of some authorized signer’s PRF while hiding the specific signer’s identity within some set of possible signers, known as the ring. We propose ring VRFs as a natural fulcrum around which a diverse array of zkSNARK circuits turn, making them an ideal target for optimization ...

Talk by Daniel Hugenroth (University of Cambridge) Abstract: Smartphones have become the primary computing devices for many. As such we ask them to do more and more with the limited energy stored in their battery. In this talk we look at decentralized applications and discuss how mobile network transmissions and CPU usage affect battery life based on measurements with an open-source test setup....
