Mitigation of liveness attacks in DAG-based ledgers
Darcy Camargo, Andreas Penzkofer, Sebastian Müller +1
The robust construction of the ledger data structure is an essential ingredient for the safe operation of a distributed ledger. While in traditional linear blockchain systems, perm…
Tangle 2.0 Leaderless Nakamoto Consensus on the Heaviest DAG
Sebastian Müller, Andreas Penzkofer, Nikita Polyanskii +3
We introduce the theoretical foundations of the Tangle 2.0, a probabilistic leaderless consensus protocol based on a directed acyclic graph (DAG) called the Tangle. The Tangle natu…
Reality-based UTXO Ledger
Sebastian Müller, Andreas Penzkofer, Nikita Polyanskii +3
The Unspent Transaction Output (UTXO) model is commonly used in the field of Distributed Ledger Technology (DLT) to transfer value between participants. One of its advantages is th…
Salt-based autopeering for DLT-networks
Sebastian Müller, Angelo Capossele, Bartosz Kuśmierz +6
The security of any Distributed Ledger Technology (DLT) depends on the safety of the network layer. Much effort has been put into understanding the consensus layer of DLTs. However…
Secure Access Control for DAG-based Distributed Ledgers
Lianna Zhao, Luigi Vigneri, Andrew Cullen +3
Access control is a fundamental component of the design of distributed ledgers, influencing many aspects of their design, such as fairness, efficiency, traditional notions of netwo…
Access Control for Distributed Ledgers in the Internet of Things: A Networking Approach
Andrew Cullen, Pietro Ferraro, William Sanders +2
In the Internet of Things (IoT) domain, devices need a platform to transact seamlessly without a trusted intermediary. Although Distributed Ledger Technologies (DLTs) could provide…
Parasite Chain Detection in the IOTA Protocol
Andreas Penzkofer, Bartosz Kusmierz, Angelo Capossele +2
In recent years several distributed ledger technologies based on directed acyclic graphs (DAGs) have appeared on the market. Similar to blockchain technologies, DAG-based systems a…
Properties of the Tangle for Uniform Random and Random Walk Tip Selection
Bartosz Kusmierz, William Sanders, Andreas Penzkofer +2
The growing number of applications for distributed ledger technologies is driving both industry and academia to solve the limitations of blockchain, particularly its scalability is…
