- Why the forks happened
- 2017: Bitcoin Cash (BCH) split from Bitcoin (BTC) over how to scale (on‑chain big blocks vs. off‑chain/Layer‑2 like Lightning, conservative changes, and decentralization concerns).
- 2018: Bitcoin SV (BSV) split from BCH, advocating very large blocks and a “set-in-stone” protocol closer (in their view) to the 2009 design.
