Does the length of time passing between elections and the announcement of elections results increase the risk of post-election violence? The declaration of official election results is a crucial moment in the electoral cycle. When electoral management bodies (EMBs) take longer than expected to announce official election results, it can signal to the opposition that the election is being stolen. Following this logic, this paper argues that the length of time between elections and the announcement of the official results acts as a signal of possible voter fraud, thereby increasing incentives for post-election violence. Hence, the paper hypothesises that a long length of time between elections and the announcement of official results increases the risk of post-election violence. This hypothesis is examined with an original dataset of election results declarations in African countries from 1997 to 2022. After controlling for important confounders that could influence delays in reporting and violence, the article empirically demonstrates that a longer length of time between elections and the announcement of official election results increases the risk of post-election violence. In doing so, this paper makes a significant contribution to studies of elections, and electoral violence. Its provision of a new dataset on election results declarations in African countries is also a significant contribution.

Publisher Copyright: © 2013 IEEE. | openaire: EC/H2020/779984/EU//SOFIE ; The Ethereum blockchain is one of the most popular permissionless blockchains. A consequence of its popularity has been the growth of processing and data storage requirements for any node participating in the Ethereum blockchain network. For constrained devices such requirements are often infeasible to meet. To cater for such nodes, a so-called light protocol has been proposed for Ethereum where the responsibility of maintaining a correct state representation is delegated to light protocol servers. Previous research has identified dependence on external state management as a potential security vulnerability that exclusively impacts light nodes. Although a simple mitigation strategy is available, it comes at the expense of increased latency. In this work, we propose a new Ethereum node type, which we call a subset node, as an extension of the light protocol. Our proposal allows subset nodes to gain a lower latency than a pure light node with comparable or even higher security assurances by tracking and evaluating only a subset of all of the transactions issued on the blockchain. We provide a formal proof on the correctness of the blockchain state used by the subset node under the proposed model. To evaluate the practical feasibility of the subset node model, we analyze one year of historical transaction data from Ethereum, and demonstrate that a subset node tracking the state of a single account can achieve a significant reduction in storage and computational requirements when compared to a full node. ; Peer reviewed
