We presented our publication “A Policy-Based Mitigation of Transaction Exclusion in Ethereum” at this year’s ACM Symposium on Access Control Models and Technologies in Stony Brook, New York, USA. In this work, we demonstrate how users can register desired policies in Ethereum, which are then enforced at the protocol level. Furthermore, we propose a concrete policy that makes transaction censorship economically unattractive.

We could present our publication “To the Best of Knowledge and Belief: On Eventually Consistent Access Control” on this year's ACM Conference on Data and Application Security and Privacy (CODASPY) in Pittsburgh, Pennsylvania. At the example of decentralized communication systems like Matrix, we showed that traditional conceptual models of access control are insufficient, and present “Eventually Consistent Access Control” as alternative.

We presented our new publication "Price Oracle Accuracy Across Blockchains: A Measurement and Analysis" at this year's "Workshop on Cryptoasset Analytics". Using the example of Chainlink, the paper examines how accurately price data from centralized trading venues is mapped on different blockchain systems and which trade-offs result from configurations of heartbeat and threshold.

We have presented our new publication “Proof-Carrying CRDTs allow Succinct Non-Interactive Byzantine Update Validation” on this year's Workshop on Principles and Practice of Consistency for Distributed Data. In this work,  Conflict-Free Replicated Data Types (CRDTs) are combined first-time with non-interactive cryptographic proofs, as they are known from the zero-knowledge field.
