What is Blockchain Trilemma?

The Blockchain Trilemma refers to the challenge in achieving a balance between scalability, decentralization, and security in a blockchain network. While scalability refers to the speed and volume of transactions, decentralization refers to the distribution of network nodes, and security refers to the integrity of the system from compromise. The Blockchain Trilemma states that an equal prioritization of all three factors at once is impossible — so a trade-off must be made with one. It remains an ambition of blockchain technologists and entrepreneurs to solve the trilemma with greater effectiveness in the design of any network, update, or application.
