In the synchronous C-counting problem, all nodes need to eventually agree on a counter that is increased by one modulo C in each round for given C&gt;1. In the self-stabilising firing squad problem, the task is to eventually guarantee that all non-faulty nodes have simultaneous responses to external inputs: if a subset of the correct nodes receive an external “go” signal as input, then all correct nodes should agree on a round (in the not-too-distant future) in which to jointly output a “fire” signal. Moreover, no node should generate a “fire” signal without some correct node having previously received a “go” signal as input. We present a framework reducing both tasks to binary consensus at very small cost. For example, we obtain a deterministic algorithm for self-stabilising Byzantine firing squads with optimal resilience f&lt;n/3, asymptotically optimal stabilisation and response time O(f), and message size O(log f). As our framework does not restrict the type of consensus routines used, we also obtain efficient randomised solutions."}],"file_date_updated":"2020-07-14T12:48:01Z","author":[{"last_name":"Lenzen","full_name":"Lenzen, Christoph","first_name":"Christoph"},{"first_name":"Joel","id":"334EFD2E-F248-11E8-B48F-1D18A9856A87","last_name":"Rybicki","full_name":"Rybicki, Joel","orcid":"0000-0002-6432-6646"}],"year":"2018","scopus_import":"1","month":"09","quality_controlled":"1","doi":"10.1007/s00446-018-0342-6","publisher":"Springer","citation":{"apa":"Lenzen, C., &#38; Rybicki, J.
