Bitcoin Cash (BCH) is a decentralized digital currency that emerged as a result of a hard fork from the original Bitcoin blockchain on August 1, 2017. Designed to fulfill the vision of peer-to-peer electronic cash, Bitcoin Cash enhances transaction speed and reduces fees by increasing block size limits. With its focus on usability for everyday payments and large-scale commercial transactions, BCH stands out in the evolving cryptocurrency ecosystem.
The Origins of Bitcoin Cash
Bitcoin Cash was created in response to growing concerns about Bitcoin’s scalability. As Bitcoin adoption increased, network congestion led to slower transaction times and higher fees. The core issue stemmed from Bitcoin’s 1 MB block size limit, which restricted the number of transactions per second.
To address this, a segment of the Bitcoin community advocated for larger blocks. When consensus couldn’t be reached, a hard fork occurred at block height 478,558, giving birth to Bitcoin Cash. This new chain increased the block size to 8 MB—later expanded further—enabling faster processing and lower costs.

Technical Advantages of Bitcoin Cash
Larger Block Size for Faster Transactions
One of the defining features of Bitcoin Cash is its significantly larger block size compared to Bitcoin. While Bitcoin remains capped at 1 MB (effectively up to 4 MB with SegWit), Bitcoin Cash supports blocks up to 32 MB. This allows the network to handle more transactions per second (TPS), reducing confirmation times and making microtransactions feasible.
Same Consensus Mechanism, Enhanced Performance
Like Bitcoin, Bitcoin Cash uses the SHA-256d proof-of-work (PoW) consensus algorithm. This ensures compatibility with existing mining hardware and maintains a high level of security. Miners continue to validate transactions and secure the network through computational power, preserving decentralization while improving throughput.
Regular Network Upgrades
Bitcoin Cash follows a biannual upgrade schedule, typically occurring on May 15 and November 15 each year. These upgrades allow developers to introduce new features, improve protocol efficiency, and adapt to changing user needs without disrupting network stability.
Notable upgrades include:
- May 2018: Introduction of Schnorr signatures and restoration of certain opcodes for smart contract functionality.
- November 2020: Implementation of the ASERT difficulty adjustment algorithm (aserti3-2d), improving mining stability and responsiveness.
- Fork Split: In November 2020, a contentious upgrade led to a split between Bitcoin Cash Node (BCHN) and Bitcoin Cash ABC (BCHA), with BCHN emerging as the dominant chain.
Market Performance and Key Metrics
As of recent data, Bitcoin Cash maintains a strong presence in the cryptocurrency market:
- Circulating Supply: ~19.89 million BCH
- Total Supply Cap: 21 million BCH (matching Bitcoin’s limit)
- Market Capitalization: Approximately $9.52 billion
- 24-Hour Trading Volume: Over $688 million
- Block Reward: Currently 6.25 BCH per block (post-halving)
The first halving event occurred on April 8, 2020, at block height 630,000, reducing the block reward from 12.5 to 6.25 BCH. This deflationary mechanism mirrors Bitcoin’s supply model, aiming to preserve long-term value.
Use Cases and Real-World Adoption
Bitcoin Cash was designed with practical spending in mind. Its low transaction fees—often less than $0.01—and fast confirmation times make it ideal for:
- Retail Payments: Merchants can accept BCH without high processing fees or chargebacks.
- Cross-Border Transfers: Users can send money globally without intermediaries or delays.
- Micropayments: Content creators and service providers use BCH for pay-per-use models.
Major platforms like BitPay and Blockchain.com have integrated support for Bitcoin Cash, enabling wallet storage and transaction processing. This institutional recognition strengthens BCH’s credibility and usability.

Frequently Asked Questions (FAQ)
What is the main difference between Bitcoin and Bitcoin Cash?
The primary distinction lies in block size. Bitcoin Cash increased the block limit to accommodate more transactions per second, prioritizing fast and low-cost payments. In contrast, Bitcoin focuses more on being a store of value, with slower but highly secure transactions.
Is Bitcoin Cash secure?
Yes. Bitcoin Cash uses the same SHA-256d proof-of-work mechanism as Bitcoin, ensuring robust security through decentralized mining. Its large hash rate makes it resistant to attacks, comparable to other top-tier PoW networks.
Does Bitcoin Cash support smart contracts?
While not as advanced as Ethereum, Bitcoin Cash has restored several scripting opcodes that enable basic smart contract functionality. Developers are actively exploring use cases like token issuance and decentralized applications (dApps) on the BCH chain.
How often does Bitcoin Cash undergo upgrades?
Bitcoin Cash typically upgrades every six months, on May 15 and November 15. These scheduled improvements allow for continuous innovation while maintaining network predictability.
Can I mine Bitcoin Cash?
Yes. Since it uses SHA-256d, the same mining equipment used for Bitcoin can mine Bitcoin Cash. However, miners must choose which chain to support based on profitability and ideological alignment.
What happened during the 2020 Bitcoin Cash fork?
In November 2020, a disagreement over protocol development led to a split between two major implementations: Bitcoin Cash Node (BCHN) and Bitcoin Cash ABC (BCHA). BCHN gained broader community support and became the dominant version of Bitcoin Cash.
The Future of Bitcoin Cash
Bitcoin Cash continues to champion the original vision of digital cash—fast, cheap, and accessible to all. While competition from newer payment-focused blockchains exists, BCH benefits from early adoption, proven security, and an active development community.
Future developments may include enhanced privacy features, improved scripting capabilities, and deeper integration with payment processors. As global demand for decentralized financial tools grows, Bitcoin Cash remains positioned as a viable alternative for daily transactions.
