Bitcoin Cash (BCH) emerged in August 2017 as a hard fork of the Bitcoin network, aiming to fulfill the original vision of peer-to-peer electronic cash. Designed for speed, low cost, and scalability, BCH reimagines how cryptocurrency can function in everyday transactions. By increasing block size and prioritizing on-chain capacity, it offers an alternative path to Bitcoin’s evolution—one focused on usability over store-of-value dominance.
This article explores the origins, technical design, real-world applications, and ongoing challenges of Bitcoin Cash, shedding light on why it chose to diverge from Bitcoin and what that means for users and investors today.
The Genesis of Bitcoin Cash: A Response to Bitcoin's Limitations
In the mid-2010s, Bitcoin began facing significant network congestion. As adoption grew between 2016 and 2017, the 1MB block size limit led to delayed transaction confirmations and soaring fees—sometimes exceeding $20 per transaction. For many, this undermined Bitcoin’s potential as a practical payment method.
A faction within the crypto community argued that Bitcoin should remain first and foremost a digital cash system rather than evolve into a high-value settlement layer. This group believed the solution was simple: increase the block size to allow more transactions per block. When consensus couldn’t be reached within the broader Bitcoin community, a hard fork occurred on August 1, 2017, giving birth to Bitcoin Cash (BCH).

Big Blocks, Faster Transactions: The Core Philosophy Behind BCH
The defining feature of Bitcoin Cash is its larger block size. While Bitcoin stuck with 1MB (later improved via SegWit), BCH initially increased blocks to 8MB and eventually scaled up to 32MB. This expansion allows the network to process significantly more transactions per second—up to around 200 TPS under optimal conditions—compared to Bitcoin’s typical 3–7 TPS.
By accommodating more data per block, BCH reduces competition among transactions, leading to lower fees and faster confirmations. In practice, average transaction costs on the BCH network often fall below $0.01, making micropayments and daily purchases feasible.
This "big block" approach reflects a fundamental belief: on-chain scaling is the most straightforward and secure way to achieve mass adoption. Instead of relying on second-layer solutions like the Lightning Network, BCH proponents advocate for keeping transactions directly on the main chain for transparency and accessibility.
How the Hard Fork Worked: A Split in Ideology
The creation of BCH wasn’t just a technical update—it was a community-driven split rooted in philosophical differences. Developers, miners, and users who supported larger blocks coordinated the hard fork, ensuring backward compatibility with Bitcoin’s ledger up to the point of divergence.
As a result, anyone holding Bitcoin at the time of the fork automatically received an equal amount of BCH at a 1:1 ratio. This fair distribution model helped BCH gain immediate traction and miner support.
Despite initial momentum, the long-term trajectory of BCH has been shaped by continued innovation—and further splits. In 2018, another ideological rift led to the emergence of Bitcoin SV (BSV), which pushed for even larger blocks. These divisions highlight the challenges of decentralized governance but also underscore the importance of aligning technological vision with community consensus.
Technical Design and Network Performance
Like Bitcoin, Bitcoin Cash uses the SHA-256 proof-of-work (PoW) consensus algorithm and maintains a fixed supply cap of 21 million coins. It also follows the same four-year halving schedule, where block rewards are cut in half approximately every four years.
However, beyond block size, BCH has introduced several protocol upgrades:
- Adjustable difficulty algorithms: To maintain consistent block times despite fluctuating hash power.
- Replay protection: Prevents transactions on one chain from being valid on the other after a fork.
- CashAddr format: Improves address readability and security.
- Smart contract enhancements: Recent upgrades have improved virtual machine performance and enabled high-precision arithmetic operations.
In a notable 2018 stress test, a single BCH block processed over 25,000 transactions, demonstrating its capacity under heavy load. By contrast, typical Bitcoin blocks handle between 1,000 and 1,500 transactions.
While these metrics showcase BCH’s throughput advantages, larger blocks also bring trade-offs—such as increased bandwidth requirements and longer synchronization times for full nodes. These factors can affect decentralization by making it harder for individual users to run nodes independently.
Real-World Use Cases: From Payments to DeFi
Bitcoin Cash’s low fees and fast confirmations make it well-suited for real-time payments. Merchants and service providers around the world accept BCH for goods and services—from online gaming platforms to international remittances.
Moreover, the 2023 introduction of CashTokens has expanded BCH’s utility beyond simple transfers. This token standard enables:
- Issuance of custom tokens
- NFT creation
- Decentralized finance (DeFi) applications
With these developments, BCH is no longer just an electronic cash system—it’s evolving into a platform capable of supporting complex financial interactions while maintaining low costs and high throughput.
Although not yet mainstream, growing interest in microtransactions and borderless payments continues to fuel innovation within the BCH ecosystem.

Challenges Facing Bitcoin Cash
Despite its strengths, BCH faces several hurdles:
- Lower network security: Compared to Bitcoin, BCH has less hash power securing its network, making it potentially more vulnerable to attacks.
- Reduced merchant adoption: Fewer businesses accept BCH compared to BTC or stablecoins like USDT.
- Competition from layered solutions: Bitcoin’s adoption of SegWit and the Lightning Network has narrowed the performance gap.
- Community fragmentation: Past forks have diluted developer focus and public trust.
- Market liquidity and visibility: BCH trades at a fraction of Bitcoin’s volume and market cap.
These factors contribute to a perception issue: while technically capable, BCH struggles to gain widespread recognition as a go-to payment currency.
Frequently Asked Questions (FAQ)
What is Bitcoin Cash (BCH)?
Bitcoin Cash is a cryptocurrency created in 2017 through a hard fork of Bitcoin. It aims to serve as peer-to-peer electronic cash by increasing block size for faster, cheaper transactions.
How does BCH differ from BTC?
The main differences are block size (up to 32MB vs BTC’s ~4MB with SegWit), transaction fees (typically under $0.01 vs variable BTC fees), and philosophical focus—BCH prioritizes on-chain scaling for payments.
Can I use BCH for everyday purchases?
Yes. Many online merchants and service providers accept BCH due to its fast confirmations and minimal fees. Its use in micropayments and cross-border transfers is particularly promising.
Is Bitcoin Cash secure?
BCH uses proven SHA-256 PoW security but has less mining hash power than Bitcoin, resulting in a lower overall security margin. Users should assess risk accordingly.
