Bitcoin SV (BSV) emerged in late 2018 as a notable name in the cryptocurrency space, sparking interest and debate among investors and developers alike. But what exactly is BSV, and how does it differ from Bitcoin ABC and other digital currencies? This guide dives deep into the origins, technical distinctions, and potential future of Bitcoin SV—offering a clear, comprehensive overview for both newcomers and seasoned crypto enthusiasts.
Understanding Bitcoin SV (BSV)
A Fork of Bitcoin Cash (BCH)
Bitcoin SV is the result of a hard fork from Bitcoin Cash (BCH), which occurred in November 2018. The split was driven by ideological differences within the BCH community about the future direction of the cryptocurrency. While Bitcoin Cash itself originated as a hard fork of Bitcoin (BTC) in 2017—aimed at solving scalability issues—BSV sought to take the concept even further.
The core philosophy behind BSV was to return to what its supporters believe is the original vision of Bitcoin: a peer-to-peer electronic cash system capable of handling massive transaction volumes with low fees and fast confirmation times.

Craig Wright and the "Satoshi Vision"
Central to the BSV narrative is Dr. Craig Wright, an Australian computer scientist who claims to be Satoshi Nakamoto—the pseudonymous creator of Bitcoin. While this claim remains unverified and widely debated, Wright has been a prominent figure in the development of BSV.
The "SV" in Bitcoin SV stands for Satoshi Vision, reflecting the project's goal of restoring what Wright and his supporters see as Satoshi’s original blueprint for Bitcoin. This includes larger block sizes, simplified protocols, and a focus on on-chain scaling rather than off-chain solutions like the Lightning Network.
Wright previously supported Bitcoin Cash after its 2017 split from BTC, believing it better aligned with decentralization and usability. However, when BCH began exploring new features such as smart contract capabilities, Wright opposed these changes—leading to the creation of BSV.
Why Did Bitcoin Cash (BCH) Fork from Bitcoin (BTC)?
To fully understand BSV, we must first examine why Bitcoin Cash existed in the first place.
Addressing Bitcoin’s Scalability Problem
Bitcoin’s original 1MB block size limit became a bottleneck as network usage grew. With more transactions competing for limited block space, fees rose and confirmation times slowed—undermining Bitcoin’s viability as a daily payment system.
This issue, known as the scalability problem, led to intense debate within the Bitcoin community. One faction advocated for Segregated Witness (SegWit) and layer-2 solutions, while another pushed for increasing block size directly.
In 2017, the latter group executed a hard fork, creating Bitcoin Cash with an initial 8MB block size—eight times larger than BTC’s at the time. This allowed BCH to process more transactions per second and maintain lower fees.
Although other attempts were made to scale Bitcoin through bigger blocks, most failed due to security concerns or lack of miner support. Bitcoin Cash ultimately became the dominant chain pursuing on-chain scaling.
The Birth of Bitcoin ABC and the Second Fork
The Emergence of Bitcoin ABC
After BCH’s creation, development continued under various teams. One major proposal came from Bitcoin ABC ( Adjustable Blocksize Cap ), led by Amaury Séchet. This client aimed to evolve BCH by adding new functionalities, including smart contracts similar to those found on Ethereum.
While some saw this as innovation, others—including Craig Wright—viewed it as a deviation from Bitcoin’s core principles. They argued that adding complex features would compromise security, centralize control, and move away from peer-to-peer cash use.
BSV vs. Bitcoin ABC: Key Differences
| Feature | Bitcoin SV (BSV) | Bitcoin ABC |
|---|---|---|
| Philosophy | Return to Satoshi’s original vision | Evolve BCH with new features |
| Block Size | Increased to 128MB+ | Initially 32MB, later reduced |
| Smart Contracts | Minimalist approach | Full smart contract support |
| Governance | Centralized under nChain/Wright | Decentralized developer team |
| Target Use Case | High-throughput payments & data storage | Programmable money & dApps |
In essence:
- Bitcoin ABC leaned toward becoming a platform for decentralized applications (dApps), much like Ethereum.
- Bitcoin SV prioritized stability, simplicity, and massive on-chain scaling—ideal for micropayments, enterprise use, and data embedding.

The Hash War: BSV vs. Bitcoin ABC
What Was the Hash War?
When both BSV and Bitcoin ABC launched in November 2018, a fierce competition known as the hash war erupted. Both chains claimed legitimacy as the true continuation of Bitcoin Cash, leading to a battle for mining power—or hash rate.
Hash rate measures the computational power securing a blockchain. The higher the hash rate, the more secure and resilient the network is against attacks.
During the hash war:
- Miners had to choose which chain to support.
- Both sides invested heavily in acquiring mining equipment.
- Temporary reorganizations (re-orgs) occurred as dominance shifted.
On November 26, 2018, Craig Wright declared victory for BSV after his faction briefly achieved superior hash power. However, this lead didn’t last.
Outcome of the Conflict
Ultimately:
- Bitcoin ABC retained the ticker symbol “BCH” and broader market recognition.
- BSV continued independently under its own ticker.
- Exchanges gradually listed both assets separately.
- The hash war subsided as mining resources stabilized across chains.
Despite losing naming rights, BSV maintained a dedicated community focused on enterprise adoption and large-scale blockchain applications.
Evaluating the Future Potential of Bitcoin SV
Network Health: Nodes and Hash Rate
As of late 2018, BSV had only about one-sixth the number of nodes compared to Bitcoin ABC. Node count reflects network decentralization and user participation—fewer nodes can imply weaker resilience.
However, hash rate is equally critical. A high hash rate ensures faster block generation and stronger protection against attacks like 51% attacks, where a single entity gains majority control over mining power and manipulates transactions.
While BSV briefly led in hash rate during the war, ABC eventually regained dominance. That said, BSV’s long-term strategy isn’t just about competing with BCH—it’s about building infrastructure for global data and payment systems.
The Risk of 51% Attacks
A 51% attack allows malicious actors to reverse transactions or perform double-spending. Smaller networks with low hash rates are more vulnerable.
During the hash war, fears arose that Wright’s coalition might launch such an attack on ABC. Though never confirmed, the concern highlighted the risks inherent in contested forks.
Today, while BSV remains smaller than major cryptocurrencies, its focus on institutional partnerships has helped stabilize its network.
