What is a Layer 2(or Layer X)?

A function label, with preset criteria and attributed purpose or task for the environment or system it pertains to.

Rollups, validiums, etc., are just objects intended to fit this function label.

L stands for ‘Layer’.

The sequence of numbers determines which one precedes the other and which one is dependent on the other. Eg. L2 runs on L1.

Each layer is typically a blockchain.
