Bitcoin SV stands for Satoshi Vision.

Stemming from Bitcoin Cash, BSV is a hard fork (community-activated update to the protocol or code) established as distinct from BCH after the network upgrade scheduled for November 15th, 2018 resulted in a hash war determining the chains would be split. According to their website, the Bitcoin SV project is primarily backed by CoinGeek Mining with development work by nChain.
