Bitcoin Cash (BCH) is a cryptocurrency that emerged as a result of a hard fork from the original Bitcoin (BTC) in 2017. Designed to address Bitcoin's scalability issues, Bitcoin Cash increased the block size limit to 8MB, enabling faster transactions and lower fees. This guide explores Bitcoin Cash's technology, history, market acceptance, and future prospects.
What Is Bitcoin Cash?
Bitcoin Cash is both a payment system and a cryptocurrency created to fulfill Bitcoin's original vision as peer-to-peer electronic cash. Key features include:
- Larger block size: 8MB compared to Bitcoin's 1MB
- Faster transactions: Reduced congestion and delays
- Lower fees: More affordable for small transactions
- Shared history: BCH holders received coins equivalent to their BTC holdings at the time of the fork (August 1, 2017)

The Bitcoin Scalability Debate: Why Bitcoin Cash Was Created
The Block Size Limitation Problem
Bitcoin's 1MB block size limit, initially implemented to prevent network attacks, became a bottleneck as adoption grew. By 2017, the network could only process:
- 2,500 transactions per block
- Approximately 6 blocks per hour
- Resulting in high fees (sometimes exceeding the transaction amount itself)
Competing Solutions
Two primary solutions emerged:
- Bitcoin Unlimited: Proposed removing block size limits entirely
- Segregated Witness (SegWit): Suggested moving some data off-chain
The compromise solution, SegWit2x, planned to:
- Implement SegWit
- Later increase block size to 2MB
When some developers doubted the block size increase would happen, Bitcoin Cash was born.
Bitcoin Cash Technology: How It Works
Key Technical Differences from Bitcoin
- 8MB block size: Allows more transactions per block
- Emergency Difficulty Adjustment (EDA): Initially used to stabilize mining
- New signature hashing algorithm: Prevents transaction replay attacks
Development Philosophy
Unlike Bitcoin's core development team, Bitcoin Cash has multiple independent development groups, promoting decentralization.
