Bitcoin Cash (BCH) is a prominent cryptocurrency that emerged from a hard fork of the original Bitcoin (BTC) blockchain in 2017. Designed as a peer-to-peer electronic cash system, BCH aims to fulfill Satoshi Nakamoto’s original vision of fast, low-cost, and globally accessible digital payments. With technical enhancements such as larger block sizes, improved transaction signatures, and regular network upgrades, Bitcoin Cash continues to position itself as a scalable alternative to both traditional finance and other cryptocurrencies.
Core Features of Bitcoin Cash
On-Chain Scaling for Global Adoption
Bitcoin Cash follows a clear roadmap focused on on-chain scaling, allowing it to process more transactions per block than Bitcoin. The default block size was increased to 8MB—a significant upgrade from Bitcoin’s 1MB limit—enabling faster confirmation times and reduced network congestion. This design choice supports BCH’s mission: to serve as practical digital cash for everyday use.
Ongoing research explores further increases in block capacity, ensuring long-term scalability as adoption grows. Unlike networks that rely heavily on layer-2 solutions, BCH prioritizes base-layer efficiency, minimizing complexity for users and merchants.
Enhanced Transaction Security with New SigHash
To improve security and prevent replay attacks between BTC and BCH chains, Bitcoin Cash introduced a new signature hashing (SigHash) mechanism. This update not only strengthens protection against transaction malleability but also enhances compatibility with hardware wallets. By resolving the "double-hash" issue present in earlier implementations, BCH ensures greater reliability in transaction validation.
Dynamic Difficulty Adjustment Algorithm (DAA)
The responsive Proof-of-Work (PoW) difficulty adjustment algorithm allows miners to switch between chains based on profitability without causing drastic hash rate fluctuations. This feature stabilizes the network during periods of volatility and protects against sudden drops in mining activity, contributing to consistent block times and overall network resilience.
Decentralized Development Ecosystem
Unlike projects controlled by a single development team, Bitcoin Cash benefits from multiple independent groups contributing to its protocol. This decentralized approach reduces the risk of centralized control or ideological capture. Collaboration happens transparently via platforms like the bitcoin-ml mailing list, where developers propose and debate changes before implementation.

Real-World Applications of Bitcoin Cash
Fast and Efficient Transactions
Designed for speed, the Bitcoin Cash network confirms transactions within minutes—even during peak usage. Larger blocks mean more transactions can be processed per second, reducing competition among users to get their transactions included. As a result, even low-fee transactions are reliably confirmed quickly, making BCH ideal for time-sensitive payments.
Affordable for Consumers and Merchants
Low transaction fees make Bitcoin Cash highly attractive for both individuals and businesses. While credit card processors often charge merchants 2–3% per transaction plus fixed fees, BCH eliminates these costs entirely. There are no monthly subscription fees, no chargebacks, and no intermediary markup. Additionally, because BCH is borderless and decentralized, it removes foreign exchange fees associated with international transactions.
Fraud Resistance Through Irreversible Payments
One of the biggest risks in e-commerce is payment fraud, particularly chargebacks ("friendly fraud"). With Bitcoin Cash, once a transaction is confirmed, it cannot be reversed—providing strong protection for sellers. This immutability reduces operational risk and administrative overhead, especially for online retailers operating across jurisdictions.
Simple Integration for Businesses
Small businesses can start accepting BCH with minimal setup. All that's needed is a Bitcoin Cash wallet address and a QR code generator—often available through free mobile apps. For larger operations, platforms like Coinbase Commerce allow seamless integration into existing e-commerce systems such as Shopify or WooCommerce. Setup typically requires only an email address and phone number.
Continuous Network Improvements
The Bitcoin Cash community is committed to regular upgrades that enhance usability and functionality. One notable improvement is the introduction of the “bitcoincash:” prefix in addresses. This change helps prevent user errors when scanning QR codes, clearly distinguishing BCH from BTC addresses and reducing the risk of lost funds.

Key Milestones in 2019: Growth and Innovation
Despite market fluctuations, 2019 was a transformative year for the Bitcoin Cash ecosystem. Two major network upgrades enhanced functionality and security:
- May 15 Upgrade (Block 582680): Introduced Schnorr signatures, which improve privacy and enable more efficient multi-signature transactions. It also implemented Segwit recovery exemption, allowing users to reclaim funds mistakenly sent to incompatible addresses.
- November 15 Upgrade (Block 609135): Enforced the Minimaldata rule, eliminating the last known source of transaction malleability. It also extended Schnorr signature support to
OP_CheckMultisig, strengthening cryptographic consistency across all transaction types.
Rise of Simple Ledger Protocol (SLP) Tokens
The SLP framework enabled token creation directly on the BCH blockchain. In 2019 alone:
- Over 6,141 unique tokens were issued
- More than 312,505 SLP transactions were recorded
Popular tokens included Honk Honk, Spice, Flex Coin, and Gocrypto. These projects demonstrated the versatility of BCH beyond simple payments, fostering innovation in gaming, community tokens, and decentralized applications.
Expansion of Infrastructure and Adoption
New platforms emerged to support the growing ecosystem:
- CryptoPhyl, a dedicated SLP exchange
- Peer-to-peer marketplaces enabling non-custodial trading
- Realmx, a video game built on the BCH blockchain
- EatBCH, a charitable initiative providing food aid using cryptocurrency donations
Physical adoption also expanded with “Bitcoin Cash Houses” launching in Venezuela and plans underway for expansion across Africa.
How Is Bitcoin Cash Different From Bitcoin?
While Bitcoin Cash shares its origins with BTC, it has evolved into a distinct digital currency with different goals and technical approaches:
| Feature | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | 1MB (with SegWit) | Up to 8MB |
| Transaction Speed | Slower due to congestion | Faster confirmations |
| Fees | High during peak times | Consistently low |
| Scaling Approach | Relies on off-chain solutions (e.g., Lightning Network) | Focuses on on-chain scaling |
| Philosophy | Store of value ("digital gold") | Peer-to-peer electronic cash |
Critics argue that larger blocks compromise decentralization, while supporters maintain that usability must come first for mass adoption. BCH advocates believe they are preserving Satoshi’s original vision—one where anyone, anywhere can send money instantly and affordably.
Frequently Asked Questions (FAQ)
Q: What is the main purpose of Bitcoin Cash?
A: Bitcoin Cash aims to be fast, low-cost digital cash for everyday transactions, prioritizing usability over speculative value.
Q: Can I still send BCH after the network upgrades?
A: Yes—upgrades are backward-compatible. Wallets supporting BCH will continue to work seamlessly.
Q: Are SLP tokens secure?
A: SLP tokens operate on the secure Bitcoin Cash blockchain. However, individual token projects vary in reliability—always research before investing.
Q: Why did Bitcoin Cash fork from Bitcoin?
A: The split occurred due to disagreements over scaling. BCH supporters favored increasing block size; BTC developers opted for SegWit and layer-2 solutions.
Q: Is Bitcoin Cash considered “real” Bitcoin?
A: While it originated from Bitcoin, BCH operates independently with its own development path and community consensus.
Q: Where can I use Bitcoin Cash today?
