I was curious, so i looked into the history of what led to rollups on Bitcoin. 
So lets do this. 

MY FIRST WARPCAST THREAD 🧵

Really, the exploration of zk-rollups on Bitcoin reflects a journey from early constraints to innovative scaling. 

You even had Satoshi talking about talking about the future of scaling back in yesteryear:

Bitcoin's early days: A tech puzzle with missing pieces.  Proof validation and script covenants were missing pieces.  2014 teased us with sidechain dreams, promising more but stuck on central controls. Was this the dead end?

2017 was a game-changer with SegWit. And an intriguing unintended consequence became apparent - it set the stage for far more versatile use of Bitcoin's blockchain data capacity. A new defined structure, the witness gave developers room for creativity by allowing arbitrary data to be stored. Still, long road ahead.

Ethereum's 2019 leap into layer 2 and zk-rollups had us all watching. Bitcoin developers watched, eager to adapt but lacked the right tools.

The 2020s brought Taproot, revolutionizing Bitcoin with Schnorr signatures and MAST for smarter transactions. BitVM's emergence promised Bitcoin-compatible complex computation, setting the stage for Citrea’s zk-rollup testnet. and here we are
