Bitcoin Cash SV is a cryptocurrency created in 2018. It is the result of a software upgrade to the Bitcoin Cash (BCH) protocol that resulted in a hard fork, which also created Bitcoin Cash ABC.[1]

Overview

In 2018, a software developer called ABC Bitcoin proposed an upgrade to the Bitcoin Cash protocol. The changes included potential scaling solutions for the cryptocurrency by changing the way its blockchain stored information. The upgrades were endorsed by Roger Ver and Bitcoin.com. They also had the potential to allow software developers to create smart contract software platforms on the Bitcoin Cash blockchain. This proposal was met with contentious feedback, especially from prominent Bitcoin Cash developer nChain and its founder, Craig Wright. In response, nChain made its own proposal for a software upgrade, which they dubbed Bitcoin Cash SV (the SV being short for "Satoshi's Vision"), which they argued would be closer to Satoshi Nakamoto's original vision. On November 15th, 2018, Bitcoin Cash forked, which began an intense conflict between miners supporting Bitcoin Cash ABC and Bitcoin Cash SV respectively.[2]

In December 2018, a cryptocurrency researcher named Reizu wrote a blog post describing how he was able to spend the same BCHSV coins twice in what is called a "0-conf transaction" double-spend. This raised serious concerns about the robustness of SV's security.[3]
