Managing Write Access without Token Fees in Leaderless DAG-based Ledgers
Darcy Camargo, Luigi Vigneri, Andrew Cullen
A significant portion of research on distributed ledgers has focused on circumventing the limitations of leader-based blockchains mainly in terms of scalability, decentralization a…
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…
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…
