Ember University: What is Layer 2?

Layer 1 blockchains are the underlying blockchains in the main architecture. For example, Bitcoin and Ethereum Mainnet are layer 1 blockchains.

Layer 2 blockchains are secondary blockchains that operate on top of the main blockchain, aka layer 1. The whole purpose of having a layer 2 blockchain is to improve scalability and cost efficiency (yay minimal gas fees).

An example of a layer 2 blockchain would be Bitcoin Lightning Network, which is a layer 2 solution for Bitcoin. Leading layer 2 solutions for Ethereum are: Polygon (MATIC), Arbritrum, Loopring.

Ember Fund is now currently building on Polygon, allowing us to offer many more exciting portfolios in the future.
