Modularity is a concept that changes the very logic of how blockchains operate. Previously, one network had to do everything at once — execute transactions, store data, ensure consensus — but now these functions can be separated across different layers.
This is like dismantling a monolithic building into separate modules that work together but do not interfere with each other.
