Blockchain plays a significant role in cryptocurrencies and growing applications like smart contracts. However, prior blockchain algorithms did not consider large-scale network partitioning a considerable concern while relying heavily on a reliable global network. Previous works have shown a possibility of a massive disruption on the Internet. The author in [2] discusses the case of Internet disorder due to solar superstorms, which can disconnect different geographical regions from each other for months. Partitioning attacks are also notable concerns that should be considered, in which their goal is to cut connections between a set of nodes and the rest of the network. In the case of network partitioning, the main chain will fork into branches, and miners in different disconnected regions will create multiple blocks in parallel. The longest chain rule in current blockchain systems accepts only one of the branches after the …
