Bitcoin Cash (BCH) emerged as one of the most significant cryptocurrencies following its hard fork from Bitcoin (BTC) on August 1, 2017. Born out of ideological and technical disagreements within the Bitcoin community, BCH aimed to solve key scalability issues that were limiting Bitcoin’s utility as a peer-to-peer electronic cash system. Since its inception, Bitcoin Cash has undergone multiple splits, giving rise to various BCH fork coins—each representing different visions for the future of decentralized digital money.
This article explores the Bitcoin cash fork history, explains what BCH fork coins are, identifies major variants like BCHABC, BCHSV, and BCHN, and analyzes their impact on the broader cryptocurrency ecosystem.
The Origins of Bitcoin Cash: Scaling Debates and Community Split
Bitcoin, launched in 2009, was designed as a decentralized digital currency enabling trustless transactions through blockchain technology. However, as adoption grew, the network faced increasing congestion. With a fixed block size of 1MB, Bitcoin could only process a limited number of transactions per second, leading to slower confirmation times and rising fees during peak usage.
To address this, a faction within the community advocated for increasing the block size limit—a proposal known as on-chain scaling. Proponents argued that larger blocks would allow more transactions per block, improving speed and reducing costs. This group believed Bitcoin should function primarily as digital cash for everyday use.
On the opposing side, core developers and many long-term holders favored maintaining small block sizes and instead promoting off-chain solutions like the Lightning Network. They warned that larger blocks could centralize mining power by favoring well-resourced operations over smaller participants, thereby undermining decentralization.
These conflicting philosophies culminated in a hard fork on August 1, 2017, resulting in the creation of Bitcoin Cash (BCH)—a new blockchain with an increased block size of 8MB (later expanded further), designed to support faster and cheaper transactions.

Understanding Hard Forks: How New Cryptocurrencies Are Born
A hard fork occurs when a blockchain undergoes a protocol upgrade that is not backward compatible. Nodes running the old software reject the new rules, causing the chain to split into two separate paths: one following the original rules and another adopting the new ones.
In the case of Bitcoin Cash, every holder of BTC at the time of the fork received an equal amount of BCH. This event marked not just a technical divergence but also a philosophical one—establishing BCH as a distinct project focused on on-chain scalability and transactional efficiency.
But the story didn't end there. Just as Bitcoin had split to create BCH, Bitcoin Cash itself would later fragment due to similar ideological disputes.
The 2018 Bitcoin Cash Fork: Birth of BCHABC and BCHSV
On November 15, 2018, Bitcoin Cash experienced another major hard fork, splitting into two competing chains:
- Bitcoin Cash ABC (BCHABC)
- Bitcoin Cash SV (BCHSV)
This split was driven by disagreements over proposed protocol upgrades, particularly around smart contract functionality and block size expansion.
Bitcoin Cash ABC (BCHABC)
Led by developer Amaury Séchet, BCHABC supported a roadmap that included:
- Continued block size increases
- Introduction of smart contract capabilities via the Canonical Transaction Ordering Rule (CTOR)
- Emphasis on innovation and usability enhancements
BCHABC positioned itself as the evolutionary path for Bitcoin Cash—balancing scalability with forward-looking features.
Bitcoin Cash SV (BCHSV)
Championed by Craig Wright and Calvin Ayre, BCHSV aimed to "restore" what they believed was Satoshi Nakamoto’s original vision:
- Massive block sizes (up to 128MB or more)
- Minimal protocol changes
- Focus on data storage and enterprise applications
Proponents claimed BCHSV adhered more closely to Bitcoin’s whitepaper principles, though critics questioned its centralization risks and practical utility.
Ultimately, BCHABC won majority hash rate support and became widely recognized as the legitimate continuation of Bitcoin Cash. The ticker symbol BCH remained associated with this chain, while BCHSV continued independently under significant controversy.
Other Notable BCH Fork Coins: Expanding the Ecosystem
Beyond the major 2018 split, several other forks have emerged from the Bitcoin Cash lineage, each introducing unique governance models or technical improvements.
Bitcoin Cash Node (BCHN)
Launched in 2020 by developer Jonathan Toomim, BCHN is a full node implementation of the Bitcoin Cash protocol emphasizing:
- Community-driven development
- Transparent decision-making
- Resistance to centralized control
Though functionally aligned with BCHABC post-fork, BCHN gained traction among users wary of corporate influence in protocol governance.
Additional Minor Forks
Other lesser-known forks include:
- eCash (XEC): A rebranding and token split of BCHABC in 2021, introducing new economic models and enhanced privacy features.
- Various experimental forks focused on privacy, smart contracts, or alternative consensus mechanisms.
These derivatives reflect ongoing experimentation within the ecosystem—proof that even mature blockchains can evolve through decentralized innovation.

Key Differences Between BTC and BCH
While both share common roots, Bitcoin (BTC) and Bitcoin Cash (BCH) differ significantly in design philosophy and performance:
| Feature | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | 1MB (effectively ~1–4 MB with SegWit) | Originally 8MB, now up to 32MB |
| Transaction Speed | Slower due to congestion | Faster confirmations |
| Fees | Higher during peak demand | Generally lower |
| Use Case Focus | Store of value ("digital gold") | Peer-to-peer electronic cash |
| Scaling Approach | Off-chain (e.g., Lightning Network) | On-chain (larger blocks) |
These distinctions highlight how forks enable divergent approaches to solving common challenges in blockchain design.
Core Keywords in Context
Throughout this discussion, key terms such as BCH fork coin, Bitcoin cash fork history, BCHABC, BCHSV, hard fork, blockchain split, and cryptocurrency evolution have been naturally integrated. These reflect high-intent search queries from users seeking clarity on Bitcoin Cash’s complex development path.
By understanding these concepts, investors and enthusiasts gain insight into how decentralization allows competing visions to coexist—and how market dynamics ultimately determine which chains survive.
Frequently Asked Questions (FAQ)
Q: What is a BCH fork coin?
A: A BCH fork coin is a cryptocurrency created through a hard fork of the Bitcoin Cash blockchain. Examples include BCHABC, BCHSV, and eCash (XEC), each representing different technical or philosophical directions.
Q: Why did Bitcoin Cash split in 2018?
A: The 2018 split occurred due to disagreements over protocol upgrades. One side supported innovation and smart contracts (BCHABC), while the other wanted massive blocks and minimal changes (BCHSV).
Q: Is BCH still relevant today?
A: Yes. Despite competition from newer blockchains, BCH remains among the top cryptocurrencies by market cap and continues to be used for low-cost, fast transactions globally.
Q: Can I own multiple fork coins from one BCH holding?
A: Yes. During each hard fork, holders typically receive an equivalent amount of the new coin if they control their private keys at the time of the split.
Q: Which BCH version is considered "official"?
A: After the 2018 fork, BCHABC retained the BCH ticker and majority network support, making it the de facto continuation of Bitcoin Cash.
Q: How do forks affect crypto security?
A: Forks can introduce temporary vulnerabilities like replay attacks. Users are advised to use updated wallets and follow security best practices during splits.
