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…
Robustness of the Tangle 2.0 Consensus
Bing-Yang Lin, Daria Dziubałtowska, Piotr Macek +2
In this paper, we investigate the performance of the Tangle 2.0 consensus protocol in a Byzantine environment. We use an agent-based simulation model that incorporates the main fea…
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…
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…
