What is the Context of Scalability Trilemma?

The state of the Scalability Trilemma is a central challenge continually addressed by blockchain developers and researchers. Key discussions involve innovative approaches to overcome these inherent limitations, such as layer-2 solutions or sharding techniques. A critical future development involves advancements that allow protocols to approach a more balanced achievement of all three properties, enhancing the utility of decentralized networks.

Scalability Trilemma

Definition

The Scalability Trilemma posits that a blockchain system can only achieve two of three desirable properties at any given time: decentralization, security, and scalability. Increasing one often necessitates a compromise on another. For instance, prioritizing high transaction throughput might reduce the number of validating nodes, affecting decentralization. This fundamental challenge shapes the design and development of all blockchain protocols.
