Bitcoin SV
November 2018 split from Bitcoin Cash — pushed for massive blocks and Craig Wright's 'Satoshi Vision'.
Forked from Bitcoin Cash
Bitcoin SV (Satoshi Vision) forked from Bitcoin Cash on November 15, 2018 during the 'hash war' between competing implementations — Bitcoin ABC (supported by Roger Ver and Bitmain) and nChain's Bitcoin SV client (backed by Craig Wright and Calvin Ayre).
BSV's defining feature was aggressive block size increases — initially 128 MB, with roadmap targets in the gigabyte range. Wright claimed the chain represented Satoshi's original vision of unbounded on-chain scaling, a claim rejected by most of the Bitcoin and Bitcoin Cash communities.
The hash war saw both sides burn hash rate on empty blocks to assert dominance. BSV ultimately became its own chain with a separate ticker. Wright's subsequent legal campaigns — including lawsuits against critics who denied he was Satoshi — kept BSV in headlines but did little for adoption.
Enterprise-focused marketing through Ayre's CoinGeek conferences positioned BSV for data storage and micropayments, but developer and exchange support remained thin compared to BTC and BCH.
Outcome
Niche chain associated primarily with Craig Wright's controversial claims. Delisted from many major exchanges after Wright's legal actions against critics.
