What is the blockchain trilemma?

The blockchain trilemma is a concept that states that it is impossible for a blockchain to simultaneously achieve all three desirable properties: decentralization, security, and scalability³. It is a widely accepted theory that decentralized networks can only provide two of three benefits at any given time¹. The blockchain trilemma is why there are so many blockchains, each taking a different approach to its solution¹.

Ongoing innovation across the decentralized ecosystem has led to a diverse range of Layer-1 and Layer-2 solutions that are working toward resolving the trilemma once and for all¹.
