Sharding has established itself as a vital technology for significantly improving all three aspects of the blockchain trilemma (security, decentralization and scalability). In a sharded blockchain the network of nodes responsible for maintaining the blockchain is divided into separate groups called shards such that each shard can process transactions in parallel. In this paper we explore and improve the communication process that happens between nodes in a shard by making use of multi-signatures. Furthermore, a realistic simulation of the communication process between nodes in a shard using multi-signatures is implemented. This simulation is used to analyze and evaluate the performance of the different sharded network communication implementations.
