Bitcoin Cash (BCH) is a "fork" of Bitcoin (BTC), designed to align more closely with Satoshi Nakamoto's original vision of a peer-to-peer electronic cash system outlined in the 2008 whitepaper. Positioned as a transactional currency, BCH aims to overcome Bitcoin's scalability challenges, making it ideal for everyday payments. Its key differentiator is a larger block size, enabling faster, cheaper transactions and emphasizing utility over mere store-of-value functionality.
Understanding Bitcoin Cash
Born from a 2017 hard fork at block 478,558, Bitcoin Cash emerged as a solution to Bitcoin's scalability issues. This split introduced protocol changes, rendering prior blocks obsolete and requiring updated software. Advocates like Roger Ver ("Bitcoin Jesus") championed BCH for its practical use in daily transactions, though critics raised concerns about centralization risks due to larger blocks.
Core Features of Bitcoin Cash
Bitcoin Cash operates as a decentralized network with these defining attributes:
- Universal Access: Open to all without central control.
- Pseudonymity: Transactions aren't tied to identities.
- Transparency: Public blockchain ledger ensures traceability.
- Decentralized Storage: Maintained by distributed nodes.
- Consensus-Driven Rules: Protocol evolves via participant agreement.
- Immutability: Recorded transactions are irreversible.
- Security: PoW mining deters attacks through high costs.
- Limited Supply: Capped at 21 million BCH.
- Low-Cost Transactions: Fees often under $0.01.

How Bitcoin Cash Works
BCH's 32MB block size (vs. Bitcoin's 1MB) processes 100+ transactions per second, making it ideal for small purchases. Key operational aspects:
- PoW Mining: Miners validate transactions for BCH rewards.
- Smart Contracts: Supports CashScript for advanced functionalities.
- Privacy Tools: CashShuffle (coin mixing) and CashFusion (transaction obfuscation) enhance anonymity.
Bitcoin vs. Bitcoin Cash: Key Differences
| Feature | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | 1MB | 32MB |
| TPS | 3–7 transactions | 100+ transactions |
| Avg. Fee | Higher (~$1–$50) | <$0.01 |
| Smart Contracts | Limited (Layer 2) | Native (Cashscript) |
| Schnorr Signatures | Yes | Yes |
| Difficulty Adjustment | Standard | ASERTI3-2D (Adaptive) |
Challenges Facing Bitcoin Cash
- Adoption Hurdles: Smaller user base than Bitcoin.
- Security Trade-offs: Lower hash rate reduces attack resistance.
- Brand Confusion: Similar naming dilutes distinct identity.
- Environmental Impact: PoW mining remains energy-intensive.

Q: What’s the difference between BCH and BSV?
A: Bitcoin SV (BSV) forked from BCH in 2018, focusing on massive blocks (TB-sized) and claiming to follow Satoshi's "original vision."
Q: How does Bitcoin Cash handle privacy?
A: Tools like CashFusion break transaction trails, though they require trust in mixing services.
Q: Why choose BCH over Bitcoin?
A: Opt for BCH if you prioritize low-cost, fast transactions for daily spending.
