Statistical detection of selfish mining in proof-of-work blockchain systems
Scientific ReportsThe core of many cryptocurrencies is the decentralised validation network operating on proof-of-work technology. In these systems, validation is done by so-called miners who can digitally sign blocks once they solve a computationally-hard problem ...

A Foundation for Ledger Structures
arXiv: Logic in Computer Science, 2020 This paper introduces an approach to constructing ledger structures for cryptocurrency systems with basic category theory. Compositional theories of resource convertibility allow us to express the material history of virtual goods, and ownership is modelled by a free construction.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Prader‐Willi syndrome (PWS) is a neurodevelopmental disorder typically caused by large deletions or imprinting defects on chromosome 15q11.2, encompassing multiple genes. While the contribution of individual genes to the PWS phenotype remains unclear, previous studies suggested that isolated deletions of MAGEL2, NDN, and MKRN3, excluding the ...
