Scalability Trilemma Definition - Glossary

Scalability Trilemma is the challenge in blockchain to balance decentralization, security, and scalability, often sacrificing one.

Scalability Trilemma is a concept in blockchain technology that highlights the difficulty of optimizing three critical aspects simultaneously decentralization, security, and scalability. Decentralization ensures no single entity controls the network. Security protects against attacks and fraud. Scalability enables the network to handle a growing number of transactions efficiently. Achieving all three at a high level is challenging. Improving two aspects often requires compromising the third. This dilemma drives ongoing innovation to build more efficient blockchain systems without sacrificing these core principles.
