abstract = {Blockchain sharding enhances transaction throughput for vote-based blockchains while preserving system decentralization. Existing sharded blockchains can only maintain reasonable performance by tolerating a smaller magnitude of adversarial nodes compared to the upper-bound adversarial population of non-sharded ones. They lack adequate distinction of adversarial behaviors, with safety attacks posing catastrophic consequences and liveness attacks being more manageable. This paper presents WaveSpreader, a novel blockchain sharding protocol in a synchronous communication network that tolerates the same upper-bound adversarial population as non-sharded blockchains. It achieves a notable transaction throughput with the help of a robust mitigation method that effectively mitigates the liveness attacks. Our study provides a comprehensive security analysis and experimental results confirming the efficacy of WaveSpreader.},

abstract = {The ethical and societal implications of artificial intelligence systems raise concerns. In this paper we outline a novel process based on applied ethics, namely Z-inspection, to assess if an AI system is trustworthy. We use the definition of trustworthy AI given by the high-level European Commission’s expert group on AI. Z-inspection is a general inspection process that can be applied to a variety of domains where AI systems are used, such as business, healthcare, public sector, among many others. To the best of our knowledge, Z-inspection is the first process to assess trustworthy AI in practice.},
