Bitcoin Cash (BCH) is more than just a cryptocurrency—it's a story of community, ideology, and the ongoing debate over what digital money should be. Born from one of the most significant hard forks in blockchain history, BCH emerged as a bold attempt to return Bitcoin to its original vision as a peer-to-peer electronic cash system. This article dives deep into the origins, evolution, and pivotal forks that shaped Bitcoin Cash into what it is today.
The Origins of Bitcoin Cash
Since Bitcoin’s inception on January 3, 2009, its popularity has grown from niche tech circles to global financial relevance. As user adoption surged, so did transaction volume. However, Bitcoin’s 1MB block size limit began to show its limitations. With each block capable of storing only a finite number of transactions, network congestion became common. Users experienced high fees and long confirmation times—sometimes hours or even days.
At its peak congestion, Bitcoin could process only about 4–7 transactions per second (TPS), far below traditional payment systems like PayPal or Alipay. This inefficiency undermined Bitcoin’s potential as a daily-use digital currency.

In 2015, voices within the Bitcoin community began calling for a solution: blockchain scaling. Miners and many users advocated increasing the block size to boost transaction capacity directly on-chain. In contrast, the Bitcoin Core development team opposed this, arguing that larger blocks could compromise decentralization due to increased node storage requirements.
Instead, they championed off-chain solutions such as Segregated Witness (SegWit) and the Lightning Network, which would move some transactions off the main chain. This philosophical divide sparked years of debate between miners, developers, and users—ultimately culminating in a hard fork.
On August 1, 2017, at block height 478,558, miners executed a hard fork. Six hours later, ViaBTC mining pool mined the first Bitcoin Cash block (block 478,559). Thus, Bitcoin Cash was born.
BCH inherited Bitcoin’s full transaction history but removed SegWit and increased the block size limit to 8MB—later expanded to 32MB—to support higher throughput and lower fees. Every Bitcoin holder received BCH at a 1:1 ratio, marking one of the largest airdrops in crypto history.
Core keywords naturally integrated: Bitcoin Cash, hard fork, blockchain scaling, SegWit, transaction throughput, miners, decentralization.
The Road to Adoption: BCH’s Development Goals
Following its launch, Bitcoin Cash positioned itself as digital cash for everyday use—fast, cheap, and reliable. In April 2018, the BCH community unveiled a mid-term development roadmap focused on two major upgrades:
- Further scaling: Increasing block size to 32MB to support global transaction volumes.
- Smart contract functionality: Reintroducing certain disabled Bitcoin script opcodes (operation codes), enabling more complex logic on-chain and allowing BCH to support decentralized applications (dApps) similar to Ethereum.
These changes aimed to transform BCH from a simple payment token into a robust platform for innovation—while staying true to on-chain scalability.
However, not everyone agreed with this direction.
The Emergence of BSV: A Clash of Visions
Dr. Craig Wright, who claims to be Satoshi Nakamoto, strongly opposed BCH’s new roadmap. He argued that Bitcoin’s original design was already perfect and needed only massive scaling—not feature additions. His vision? Lock down the protocol and scale blocks up to 128MB or beyond, restoring what he called “Bitcoin Satoshi Vision” (BSV).
To realize this, Wright backed nChain and launched the BSV node client on August 16, 2018. This set the stage for another split.
Tensions escalated throughout late 2018. The debate wasn’t just technical—it was ideological. One side wanted innovation and expanded use cases; the other demanded strict protocol adherence and unlimited scaling.
On November 15, 2018, the inevitable happened: Bitcoin Cash hard-forked again, splitting into two chains:
- BCHABC (later renamed BCH) – supporting further development and upgrades.
- BCHSV (later BSV) – committed to protocol stability and massive blocks.
The fork triggered market turmoil, with both coins seeing sharp price drops initially. But BSV pressed forward—on July 24, 2019, it increased its block size cap to 2GB, the largest among all public blockchains at the time. Days later, a 256MB block was successfully mined on BSV, setting a new record.
From one chain in 2009, we now had three major branches: BTC, BCH, and BSV—each representing a different interpretation of Satoshi’s vision.
The 2020 Fork: Infrastructure Funding vs. Miner Autonomy
Just two years later, another conflict brewed within the BCH ecosystem—this time over funding.
In 2020, the primary development team behind BCH, Bitcoin ABC, proposed an Infrastructure Funding Plan (IFP). The idea was simple: redirect 8% of each block reward to a fund supporting core developers and critical infrastructure projects. This was meant to ensure sustainable development without relying solely on donations or corporate sponsorship.
But many miners and community members saw it differently. They viewed IFP as a "miner tax"—an involuntary deduction from their rewards. Critics argued it centralized power by giving developers control over funds collected from miners.
Two camps formed:
🟢 The BCHABC (BCHA) Camp
- Supported IFP as essential for long-term growth.
- Claimed mining revenue loss would be minimal (~0.2%) due to dynamic difficulty adjustments.
- Released client version 0.21.0 with IFP code included.
🔵 The BCHN Camp
- Led by early BCH developer Freetrader.
- Created BCH Node (BCHN), a client without IFP.
- Promised no forced contributions—preserving miner sovereignty.
- Positioned itself as the true continuation of decentralized BCH values.

In the week before the fork (November 15, 2020), 84.2% of blocks were mined by BCHN nodes, while BCHA mined 0%. It was clear where miner support lay.
When the fork occurred at block 661,648, BCHN emerged victorious, becoming the dominant chain recognized as Bitcoin Cash (BCH). BCHA briefly existed but faded into obscurity.
Frequently Asked Questions (FAQ)
Q: What is Bitcoin Cash?
A: Bitcoin Cash is a peer-to-peer cryptocurrency created in 2017 via a hard fork from Bitcoin. It aims to serve as fast, low-cost digital cash by increasing block sizes to improve transaction capacity.
Q: Why did Bitcoin Cash fork from Bitcoin?
A: The fork resulted from disagreements over scalability. While Bitcoin Core favored off-chain solutions like SegWit and Lightning Network, BCH supporters believed larger blocks were necessary for on-chain scaling and practical everyday use.
Q: Is Bitcoin Cash still active?
A: Yes. After surviving multiple forks—including splits into BSV and BCHA—Bitcoin Cash continues to operate with active development, merchant adoption, and inclusion in major exchanges.
Q: How does BCH differ from BTC technically?
A: Key differences include larger block sizes (up to 32MB vs BTC’s ~4MB effective), faster transaction confirmations under load, absence of SegWit, and lower average fees.
Q: Who controls Bitcoin Cash development?
A: No single entity controls BCH. Development is community-driven, with contributions from independent teams and developers worldwide. After the 2020 fork, BCHN became the dominant implementation.
Q: Can I still receive BCH from holding BTC?
A: No. The initial distribution occurred at the time of the 2017 fork. Anyone holding BTC then received an equal amount of BCH. Future forks do not retroactively distribute new tokens unless specified.
Final Thoughts
Bitcoin Cash represents a powerful statement in the blockchain world: that money should be accessible, affordable, and usable by everyone—not just stored as digital gold.
Its journey has been turbulent—shaped by ideological battles, technical upgrades, and repeated forks—but through it all, the core mission remains unchanged: to be real money for real people.
Whether you're drawn to its scalable design, its commitment to on-chain transactions, or its resilience through controversy, Bitcoin Cash continues to play a vital role in the broader cryptocurrency ecosystem.
