The term "layer-1" refers to the foundational architecture of blockchains, on which other "layer-2" structures can be built. Improving the efficiency of layer-1 technology makes both the base blockchain itself and all the systems it supports more scalable. Ethereum is an example of a layer-1 Blockchain. However, executing efficiency-driving changes can be difficult and developers often run into the “scalability trilemma.” The trilemma stipulates that improvements in scalability cause drawbacks for decentralization and security. Q: What is a Layer -1 in Blockchain? A: refers to a collection of solutions tailored for improving the design of base protocols.
