Modular blockchains has been one of the buzz words in the last year. In this episode, let’s understand modularity in blockchains.

In the beginning, consensus and execution were part of the same blockchain like Ethereum 1.0. Then execution was decoupled and put into rollups. Then came the need for storing rollup data in the L1. And then we got DA layers as separate networks.

Now we have consensus on L1, execution on L2, and data on DA layers. This is how we have modularised the blockchains.
