Bitcoin Cash ($BCH) is a PoW-based blockchain network and the native cryptocurrency of its ecosystem. Designed for peer-to-peer transactions, online purchases, investments, and value storage, BCH emerged from a 2017 hard fork of Bitcoin (BTC), driven by debates over scalability and transaction efficiency.
Understanding the Bitcoin Cash Hard Fork
A fork represents a split in a blockchain community, occurring when protocol rules change intentionally or accidentally. In a hard fork, the original and new chains diverge completely, with no interoperability.
The BCH fork stemmed from disagreements within the Bitcoin community about:
- Scalability: Bitcoin’s 1MB block size led to delays and high fees as adoption grew.
- Vision: While BTC prioritized censorship resistance, BCH advocates focused on creating a peer-to-peer electronic cash system.
Key Upgrades in Bitcoin Cash
- Larger block sizes: Increased from 1MB to 8MB (later to 32MB in 2018), boosting transaction throughput.
- Lower fees: Optimized for everyday transactions, aligning with Satoshi Nakamoto’s original whitepaper, "Bitcoin: A Peer-to-Peer Electronic Cash System."
Shared Traits with Bitcoin
- PoW consensus
- Decentralized participation
- 10-minute block time
- Capped supply of 21 million coins
- Halving every 210,000 blocks (~4 years)

The 2018 BCH Split: BCH vs. BSV
In November 2018, BCH underwent another fork due to developer disputes:
- BCHABC (led by Bitcoin ABC, backed by Bitmain): Proposed adding smart contract functionality.
- BSV (led by nChain, "Satoshi’s Vision"): Rejected changes, claiming they betrayed Nakamoto’s vision.
Controversy: nChain’s Craig Wright has repeatedly (but unprovenly) claimed to be Satoshi Nakamoto.
