On the use of proof-of-work in permissioned blockchains: Security and fairness
In permissioned blockchains, a set of identifiable miners validates transactions and creates
new blocks. In scholarship, the proposed solution for the consensus protocol is usually …

[PDF][PDF] Reverse Bisimilarity vs. Forward Bisimilarity.
M Bernardo, S Rossi - FoSSaCS, 2023 - library.oapen.org
Reversibility is the capability of a system of undoing its own actions starting from the last
performed one, in such a way that a past consistent state is reached. This is not trivial for …

[HTML][HTML] Lumping-based equivalences in Markovian automata: Algorithms and applications to product-form analyses
In this paper we consider two relations over stochastic automata, named lumpable
bisimulation and exact equivalence, that induce a strong and an exact lumping, respectively …

Causal Reversibility Implies Time Reversibility
Several notions of reversibility exist in the literature. On the one hand, causal reversibility
establishes that an action can be undone provided that all of its consequences have been …
