Blockchain Trilemma vs Scalability

The Blockchain Trilemma describes the fundamental challenge that blockchain networks can only optimize two of three critical properties simultaneously: decentralization, security, and scalability. This technical constraint forces every blockchain project to make strategic trade-offs that define its capabilities and limitations.

The ability of a blockchain network to handle increasing numbers of transactions, users, and data without degrading performance, speed, or decentralization. Scalability measures how well a network grows to meet demand while maintaining efficiency and security.
