The promise of increased scalability and improved performance is pushing more projects to adopt a Direct Acyclic Graph (DAG) structure for their distributed ledgers instead of a traditional chain of blocks. The Workshop on DAG-based Distributed Ledger Technologies (DLTs) aims to bring together researchers and practitioners from academia and industry to discuss the latest developments and future directions in this very active field.

The workshop will focus on the DAG-based DLTs based on the Nakamoto consensus as well as on the newer development of the Byzantine Fault Tolerance (BFT) consensus. In addition, the event will explore the various modes of writing access, such as permissionless or permissioned, leaderless or leader-based, and how they impact the fairness, security, and performance of the resulting DLTs. Special attention will be given to developing appropriate and meaningful performance measures and test scenarios to compare and evaluate the performance of the most prominent DAG-based DLTs. Furthermore, due to its prominence, we welcome contributions that pertain to the topic of Maximum Extractable Value (MEV), especially concerning robustness and wealth distribution in DAG-based DLTs.

Overall, the workshop will provide a platform for participants to exchange ideas, share insights, and engage in lively discussions on the latest advances and challenges in DAG-based DLTs, focusing on the tradeoffs between fairness, security, and performance.


We welcome contributions on various aspects of DAG-based DLTs, including but not limited to

  • New DAG-based DLT designs and their implementation
  • Performance evaluation and comparison of DAG-based DLTs
  • Security and privacy in DAG-based DLTs
  • MEV in DAG-based DLTs
  • Transaction fee mechanisms
  • Writing Access in DAG-based DLTs
  • Parallel execution and dependency tracking of smart contract transactions
  • Interoperability and standardisation of DAG-based DLTs
  • Applications of DAG-based DLTs in various domains
  • Formal description and security analysis
