Low Message Complexity

Definition ∞ Low message complexity refers to a design principle in distributed systems and cryptographic protocols where the number and size of messages exchanged between participants are minimized. This design choice aims to reduce network overhead, improve communication efficiency, and enhance scalability. It is particularly important for resource-constrained environments or high-throughput applications.
Context ∞ The discussion around low message complexity is significant in the design of efficient blockchain scaling solutions, such as sharding or layer-2 protocols. A key challenge involves achieving consensus or validating transactions with minimal data transmission while maintaining robust security. Future developments will focus on optimizing cryptographic proofs and data structures to further reduce communication requirements across decentralized networks.
