Bitcoin Cash (BCH)

What is Bitcoin Cash (BCH)?

Bitcoin Cash (BCH) is a peer-to-peer electronic cash system that emerged from the Bitcoin blockchain in August 2017. Created as a hard fork of Bitcoin, BCH was designed to address what its proponents saw as Bitcoin's growing limitations as a medium of exchange for everyday transactions.

At its core, Bitcoin Cash aims to be what Bitcoin was originally intended to be: fast, reliable, and affordable digital cash for the entire world. While Bitcoin has increasingly positioned itself as "digital gold" and a store of value, Bitcoin Cash maintains focus on being a practical payment solution with low transaction fees and quick confirmation times.

For beginners, think of Bitcoin Cash as Bitcoin's sibling that took a different path. While both share the same history up until August 2017, they diverged on a fundamental question: How should the network scale to accommodate millions of users? Bitcoin Cash chose to increase the block size limit, allowing more transactions to be processed in each block, thereby reducing fees and wait times.

Today, Bitcoin Cash operates with blocks up to 32MB in size (compared to Bitcoin's 1MB base block size), processes transactions in minutes rather than hours during peak times, and typically charges fractions of a cent per transaction. This makes BCH particularly suitable for microtransactions, remittances, and merchant payments where low fees are essential.

The Great Bitcoin Fork of 2017: Understanding the Block Size Debate

The creation of Bitcoin Cash represents one of the most significant events in cryptocurrency history. To understand why BCH exists, we need to explore the Bitcoin block size debate that divided the community for years.

The Scaling Challenge

Bitcoin's network was designed with a 1MB block size limit, processing roughly 3-7 transactions per second. As Bitcoin grew in popularity between 2015 and 2017, this limitation became increasingly problematic. During peak periods, the network became congested, causing:

• Transaction fees to spike from pennies to $20-50 per transaction
• Confirmation times to extend from minutes to hours or even days
• Merchants to stop accepting Bitcoin due to unreliability
• Users to abandon Bitcoin for everyday purchases

Two Competing Solutions

The Bitcoin community split into two camps proposing different solutions:

Camp 1: Small Blocks + Layer 2 Solutions (Bitcoin Core)

• Keep the 1MB block size limit or increase it minimally
• Implement Segregated Witness (SegWit) to optimize block space
• Build second-layer solutions like the Lightning Network for off-chain transactions
• Prioritize decentralization and security over transaction capacity

Camp 2: Bigger Blocks (Bitcoin Cash)

• Increase the block size limit to allow more on-chain transactions
• Maintain low fees and fast confirmations for all transactions
• Scale primarily through larger blocks rather than complex second layers
• Prioritize usability as peer-to-peer electronic cash

The August 2017 Fork

Unable to reach consensus, the big block supporters initiated a hard fork on August 1, 2017, at block height 478,558. This created Bitcoin Cash as a separate cryptocurrency with its own blockchain, while Bitcoin continued on its original chain.

Everyone who held Bitcoin at the time of the fork received an equal amount of Bitcoin Cash, making it one of the largest "airdrops" in cryptocurrency history. This contentious split would later inspire additional forks, including Bitcoin SV (Satoshi's Vision) in 2018, which forked from Bitcoin Cash itself.

The Philosophical Divide

The block size debate was never just about technical specifications—it represented fundamentally different visions for cryptocurrency:

• Bitcoin evolved toward being a store of value and settlement layer
• Bitcoin Cash maintained focus on being electronic cash for daily transactions

This philosophical split continues to define both cryptocurrencies' development paths and community cultures.

How Bitcoin Cash Works: Technical Deep Dive

Understanding Bitcoin Cash's technology reveals why it functions differently from Bitcoin and how it achieves its goal of being fast, affordable digital cash.

Larger Block Sizes

The most prominent technical difference is Bitcoin Cash's approach to block size. BCH initially launched with an 8MB block size limit, which has since been increased to 32MB. This means:

• Each block can contain significantly more transactions
• Network capacity can handle 100+ transactions per second
• Transaction fees remain low even during high usage periods
• Miners can include more transactions per block, earning more fee revenue

Faster Transaction Confirmations

With larger blocks and typically lower network congestion, Bitcoin Cash offers:

• 0-confirmation transactions for small purchases (accepted within seconds)
• First confirmation typically within 10 minutes (same as Bitcoin's target)
• Practical finality within 1-6 confirmations depending on transaction size
• Reliable transaction processing without extended wait times

Proof of Work Consensus

Like Bitcoin, Bitcoin Cash uses the SHA-256 Proof of Work algorithm, meaning:

• Miners compete to solve cryptographic puzzles
• The longest valid chain is accepted as the true blockchain
• Same mining hardware (ASICs) can mine both BTC and BCH
• Similar security model based on computational work

Emergency Difficulty Adjustment (EDA)

Bitcoin Cash initially implemented an Emergency Difficulty Adjustment algorithm to help the network survive with variable hashrate. This was later replaced with a Difficulty Adjustment Algorithm (DAA) that adjusts mining difficulty every block, ensuring:

• Stable block production approximately every 10 minutes
• Quick adaptation to changes in network hashrate
• Prevention of extremely fast or slow block times

Smart Contract Capabilities

While not as advanced as Ethereum, Bitcoin Cash supports:

• Simple smart contracts through Script (Bitcoin's scripting language)
• More complex contracts via CashScript language
• Non-fungible tokens (NFTs) through protocols like CashTokens
• Decentralized applications (dApps) with limited functionality

Network Upgrades

Bitcoin Cash conducts scheduled hard fork upgrades approximately every six months to implement improvements, including:

• Schnorr signatures for improved privacy and efficiency
• Enhanced opcodes for smarter contracts
• Protocol improvements without community controversy
• Continuous technical evolution

Expert Verdict: Bitcoin Cash in 2024

After seven years of independent operation, Bitcoin Cash has successfully carved out a niche as a low-cost payment cryptocurrency, though it continues to face significant challenges in broader adoption.

What BCH Does Well

Bitcoin Cash delivers on its core promise: fast, affordable peer-to-peer electronic cash. Transaction fees consistently remain under a penny, making it genuinely useful for payments, remittances, and microtransactions. The network has proven reliable, with regular protocol upgrades improving functionality without major controversies. Growing merchant adoption, particularly in emerging markets, demonstrates real-world utility beyond speculation.

The development community, while smaller than Bitcoin's, has maintained steady progress. Features like CashFusion for privacy, CashTokens for NFTs and tokens, and the SmartBCH sidechain show that BCH continues to evolve and innovate.

Persistent Challenges

However, BCH faces headwinds that limit its potential. Bitcoin's brand dominance is nearly insurmountable—most newcomers to crypto buy BTC, not BCH. The narrative of Bitcoin as "digital gold" has proven more compelling to institutional investors than BCH's "digital cash" positioning.

Competition has intensified from multiple directions: Litecoin offers similar fast payments, stablecoins provide price stability for transactions, Lightning Network improves Bitcoin's payment capabilities, and traditional payment networks like Visa and PayPal have entered crypto. BCH must prove its unique value proposition in this crowded landscape.

The lower hashrate compared to Bitcoin, while never resulting in a successful attack, creates perception issues around security that matter for adoption.

Investment Perspective

As an investment, Bitcoin Cash represents a moderate-risk, moderate-reward proposition within cryptocurrency portfolios. It's unlikely to match Bitcoin's price appreciation or market dominance, but it serves a genuine purpose that could drive steady growth.

Rating: 4.0/5

BCH earns points for:

• Delivering on its technical promises (low fees, fast transactions)
• Consistent development and upgrades
• Real-world adoption and use cases
• Proven track record over 7 years

It loses points for:

• Limited growth prospects compared to Bitcoin
• Smaller network effect and ecosystem
• Market performance relative to competitors

Bottom Line

Bitcoin Cash is best suited for users and merchants who need cryptocurrency for actual transactions rather than speculation or store of value. It's a solid component of a diversified cryptocurrency portfolio, particularly for those who believe in on-chain scaling and practical payment use cases.

For investors, BCH offers exposure to the "digital cash" narrative without betting on Bitcoin itself. However, it's essential to maintain realistic expectations—Bitcoin Cash will likely remain a mid-tier cryptocurrency rather than challenging Bitcoin's dominance.

The project's future depends on continued adoption growth, particularly in emerging markets where its low fees and fast transactions provide the most value. If BCH can establish itself as the go-to cryptocurrency for remittances and daily payments in key regions, it could justify a higher market position. If not, it risks further market share erosion to competitors and stablecoins.

Frequently Asked Questions (FAQ)

Is Bitcoin Cash the same as Bitcoin?

No, Bitcoin Cash (BCH) and Bitcoin (BTC) are separate cryptocurrencies that share history only up to August 1, 2017. They split through a hard fork and now operate as independent blockchains with different technical specifications, use cases, and communities. Bitcoin focuses on being a store of value, while Bitcoin Cash emphasizes being electronic cash for daily transactions.

What caused the Bitcoin Cash fork?

The fork resulted from the block size debate within the Bitcoin community. One group wanted to keep small blocks (1MB) and scale through second-layer solutions like Lightning Network. Another group wanted larger blocks (initially 8MB, now 32MB) to scale on-chain. Unable to reach consensus, the big block supporters created Bitcoin Cash through a hard fork in August 2017.

What are Bitcoin Cash's main advantages over Bitcoin?

Bitcoin Cash offers:

• Lower fees (typically $0.001-0.01 vs $1-20+ for Bitcoin)
• Faster transaction confirmations during high network usage
• Higher throughput (100+ transactions per second vs 3-7 for Bitcoin)
• Better for payments and microtransactions

Is Bitcoin Cash a good investment?

Bitcoin Cash is a moderate-risk cryptocurrency investment suitable for diversified portfolios. It offers real-world utility as payment cryptocurrency but faces challenges from Bitcoin's dominance, competition from other payment coins, and limited institutional interest.
