Bitcoin Cash (BCH) emerged as a significant fork from the original Bitcoin blockchain, creating ongoing debates about its role in the cryptocurrency ecosystem. This guide explores its origins, technical differences, market performance, and future potential.
What is Bitcoin Cash?
Bitcoin Cash is a cryptocurrency that originated from a hard fork of Bitcoin on August 1, 2017. Created by a group of Bitcoin developers, it implemented key technical changes aimed at improving transaction speed and scalability:
- Increased Block Size: Expanded from Bitcoin's 1MB to 8MB blocks
- No SegWit Implementation: Unlike Bitcoin's Segregated Witness (SegWit) upgrade
- Lower Transaction Fees: Designed for faster, cheaper payments

The Historical Context of Bitcoin Cash's Creation
The Bitcoin Cash fork resulted from long-standing debates within the Bitcoin community about scalability solutions:
Key Events Timeline:
| Date | Event |
|---|---|
| July 2017 | Bitcoin's BIP91 proposal gains majority support |
| August 1, 2017 | Bitcoin Cash blockchain officially splits at block 478,558 |
| Post-Fork | All Bitcoin holders automatically receive equal BCH amounts |
The fork was primarily driven by mining giant Bitmain and its ViaBTC mining pool, who advocated for larger blocks rather than SegWit implementation.
Technical Differences: Bitcoin vs. Bitcoin Cash
Bitcoin Cash introduced several fundamental technical changes:
Block Size Increase
- Original Bitcoin: 1MB blocks (~7 transactions per second)
- Bitcoin Cash: 8MB blocks (later increased to 32MB)
Difficulty Adjustment Algorithm
- Implemented Emergency Difficulty Adjustment (EDA) to maintain stable mining
Transaction Signature Handling
- Different approach to transaction signatures compared to Bitcoin's SegWit
Smart Contract Capabilities
- Later added support for basic smart contracts and token creation
Market Reception and Performance
Initial market reaction to Bitcoin Cash was mixed:
- Price Volatility: BCH initially traded around $200-300 (10-15% of Bitcoin's price)
- Exchange Support: Major exchanges like Coinbase initially declined support
- Community Split: Some prominent figures like Roger Ver supported BCH

Bitcoin Cash's Evolution Since the Fork
Post-2017, Bitcoin Cash has undergone several developments:
Protocol Upgrades
- Multiple hard forks implementing new features
- Increased maximum block size to 32MB
Ecosystem Growth
- Development of wallets, payment processors
- Merchant adoption initiatives
Community Developments
- Formation of distinct developer teams
- Ongoing debates about future direction
Frequently Asked Questions
Is Bitcoin Cash the same as Bitcoin?
No. While they shared history until August 2017, Bitcoin Cash is now a separate cryptocurrency with different technical parameters and development paths.
How do Bitcoin Cash transactions differ?
Bitcoin Cash transactions are typically faster and cheaper due to larger block sizes, making it more suitable for everyday payments.
Can I still claim Bitcoin Cash from the 2017 fork?
If you held Bitcoin before August 1, 2017, you automatically received BCH. However, accessing it requires using private keys from that time.
What's the current block size of Bitcoin Cash?
As of recent upgrades, Bitcoin Cash supports blocks up to 32MB, significantly larger than Bitcoin's 1MB (with SegWit effectively allowing ~4MB).
How does Bitcoin Cash address scalability long-term?
Beyond block size increases, BCH developers are exploring other scaling solutions like pre-consensus mechanisms and adaptive block sizes.
The Future of Bitcoin Cash
The cryptocurrency continues to position itself as "electronic cash" with:
- Payment Focus: Emphasizing merchant adoption and daily transactions
- Technical Roadmap: Ongoing protocol improvements
- Market Position: Maintaining position as a top cryptocurrency by market cap
While debates continue about its relationship to Bitcoin, Bitcoin Cash has established itself as a persistent alternative with distinct technical solutions to blockchain scalability challenges.
