Report on the energy consumption of the IOTA 2.0 prototype network (GoShimmer 0.8.3) under different testing scenarios
Louis Helmer, Andreas Penzkofer
The high energy consumption of proof of work-based distributed ledgers has become an important environmental concern. Bitcoin, for example, consumes as much energy in a year as a d…
Feedback control for distributed ledgers: An attack mitigation policy for DAG-based DLTs
Pietro Ferraro, Andreas Penzkofer, Christopher King +1
In this paper we present a feedback approach to the design of an attack mitigation policy for DAG-based Distributed Ledgers. We develop a model to analyse the behaviour of the ledg…
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…
Impact of delay classes on the data structure in IOTA
Andreas Penzkofer, Olivia Saa, Daria Dziubałtowska
In distributed ledger technologies (DLTs) with a directed acyclic graph (DAG) data structure, a message-issuing node can decide where to append that message and, consequently, how…
On Fairness in Voting Consensus Protocols
Sebastian Müller, Andreas Penzkofer, Darcy Camargo +1
Voting algorithms have been widely used as consensus protocols in the realization of fault-tolerant systems. These algorithms are best suited for distributed systems of nodes with…
Fast Probabilistic Consensus with Weighted Votes
Sebastian Müller, Andreas Penzkofer, Bartosz Kuśmierz +2
The fast probabilistic consensus (FPC) is a voting consensus protocol that is robust and efficient in Byzantine infrastructure. We propose an adaption of the FPC to a setting where…
