Bitcoin Forks
This chapter looks at the major forks of Bitcoin, how and why they came about, and the different directions each community chose to pursue.

Bitcoin Satoshi Vision (BSV) – A Brief History
Origins 
 Bitcoin Satoshi Vision (BSV) emerged in November 2018 as the result of a contentious hard fork from Bitcoin Cash (BCH) . Bitcoin Cash itself had forked from Bitcoin (BTC) in August 2017 , originally to increase block sizes and pursue a vision of peer-to-peer digital cash. 
 The Dispute 
 Within the Bitcoin Cash community, disagreements grew around the technical roadmap: 
 
 
 Block Size: BCH developers favored a gradual approach to scaling, while Craig Wright and Calvin Ayre’s CoinGeek group pushed for much larger block sizes, claiming this was closer to the original whitepaper vision. 
 
 
 Script Changes & Features: BCH developers introduced new opcodes and features that BSV supporters argued deviated from “Satoshi’s Vision.” 
 
 
 The Fork 
 The conflict culminated in a hash war in November 2018, where miners aligned with each camp directed hash power to their preferred chain. The outcome was a split: 
 
 
 Bitcoin Cash ABC (later just BCH): Backed by developers like Amaury Séchet and much of the BCH community. 
 
 
 Bitcoin SV (Satoshi Vision): Backed by Craig Wright, Calvin Ayre, and their allies, with an initial block size of 128 MB, later expanded to 2 GB and beyond . 
 
 
 Philosophy 
 BSV’s stated mission is to restore Bitcoin to what its supporters believe was the “original protocol” described in the 2008 whitepaper—unbounded scaling, low-fee transactions, and enterprise-level blockchain applications. 
 Controversy 
 Since its inception, BSV has been controversial: 
 
 
 Craig Wright’s claim to be Satoshi Nakamoto is widely disputed. 
 
 
 Many exchanges delisted BSV in 2019 after public disputes. 
 
 
 Development continues under nChain and associated entities, with a focus on data storage, micro-payments, and large-scale blockchain solutions.
