What Is Bitcoin Cash?

Introduction

Bitcoin Cash exemplifies how technical choices in blockchain development can create rifts within the crypto community. Launched in August 2017, Bitcoin Cash resulted from a Bitcoin hard fork led by developers, investors, entrepreneurs, and miners who wanted a scalable alternative. Known as Bitcoin ABC (Adjustable Blocksize Cap), this project is designed as a peer-to-peer electronic cash system emphasizing fast transactions and low fees, staying closer to Satoshi Nakamoto’s original vision of a digital currency for everyday use.

Blockchain Scalability

After its inception, Bitcoin encountered significant obstacles that limited its practical use: transaction confirmation times increased substantially and fees rose, moving away from the initial premise of nearly instant, low-cost payments. These challenges sparked heated debate across the Bitcoin community regarding block size limits.

Because Bitcoin is decentralized, any protocol changes require broad consensus among all network nodes. Updating Bitcoin’s software depends on this community agreement, which often leads to ideological disputes over the project’s technical direction.

Bitcoin Cash was introduced as an innovative solution, offering greater scalability, reduced transaction fees, and faster confirmation times. The BCH community maintains that this approach is more faithful to Satoshi Nakamoto’s vision, delivering a payment system that is faster and more affordable—potentially more suitable for routine transactions than Bitcoin.

Shortly after the Bitcoin Cash fork, Bitcoin’s original blockchain adopted SegWit (Segregated Witness) via a soft fork, a technology developed by Pieter Wuille in 2015 to address network congestion and scalability. However, Bitcoin Cash proponents viewed SegWit as less effective than simply raising the block size limit. Influential leaders in the digital asset space supported the Bitcoin Cash fork.

How Does BCH Work?

Bitcoin Cash originates from Bitcoin’s source code, so the two systems share many fundamental similarities. Both networks use Proof of Work consensus and maintain open participation—anyone can join and contribute. Additionally, any address holding Bitcoin before the fork automatically received an equivalent amount of Bitcoin Cash.

Technically, BCH mirrors Bitcoin in several ways: a 10-minute target block interval and a capped supply of 21 million coins. The BCH block reward halves every 210,000 blocks, or roughly every four years, with the current reward set at 6.25 BCH.

The main difference is block size: Bitcoin’s limit is 1 MB, while Bitcoin Cash initially raised its block size to 8 MB, and later to 32 MB. This expansion theoretically allows for more transactions per block, increasing throughput. In practice, however, BCH’s average block size exceeds 1 MB only occasionally.

Both cryptocurrencies adjust mining difficulty but use different mechanisms. Bitcoin changes its difficulty every 2,016 blocks, while Bitcoin Cash does so after every block. BCH previously implemented an emergency difficulty adjustment algorithm to attract miners, but later removed it due to instability.

Bitcoin Cash adopted Schnorr Signatures, a digital signature algorithm that is simpler and more secure than Bitcoin’s ECDSA, offering improved privacy and scalability.

Key Features of BCH

Bitcoin Cash is defined by several unique features:

• Source code based on Bitcoin’s original protocol, retaining most foundational aspects
• Maximum supply capped at 21 million coins, identical to Bitcoin
• Uses Proof of Work for new coin issuance, as per the original protocol
• Increased block size from 1 MB to 32 MB, boosting transaction capacity
• The BCH community emphasizes closer alignment with Satoshi Nakamoto’s original vision
• Mining difficulty adjusts after every block using a specific algorithm
• Does not implement SegWit, positioning BCH as a technical alternative
• Integrates Schnorr Signatures, enhancing privacy and scalability
• Smart contract functionality added in later updates, expanding beyond basic transactions

Daily Payments

The Bitcoin Cash community advocates BCH as a currency designed for everyday transactions. Users can send and receive funds quickly via any BCH wallet, for both personal and commercial payments. Fast transaction speeds and low fees make BCH a practical alternative to Bitcoin for daily use, especially for small payments where fees may be a significant portion of the transaction.

Despite these advantages, Bitcoin Cash adoption for payments remains limited. Some merchants and retailers accept BCH, but it has not achieved widespread use. Over time, some businesses have accepted BCH, but many no longer explicitly offer it as a payment option, indicating outdated or inaccurate information.

How to Store Bitcoin Cash

Bitcoin Cash offers a broad and accessible storage infrastructure. Hundreds of wallets support BCH, including hardware wallets like Ledger, Trezor, and Cobo Vault for enhanced long-term security. For those preferring desktop wallets, Electrum Cash is a reliable and lightweight choice.

The Bitcoin Cash community regularly recommends various wallets for safe BCH storage. Software wallets are available for Windows, Mac, Linux, Android, and iOS, giving users flexibility across platforms.

Bitcoin and Bitcoin Cash operate on separate blockchains. You cannot send Bitcoin to a Bitcoin Cash wallet address or vice versa. Mistaken transfers result in loss of funds, so users must carefully verify wallet addresses before making transactions.

Bitcoin SV

In 2018, part of the Bitcoin Cash community initiated another hard fork to create Bitcoin Satoshi Vision (Bitcoin SV or BSV), setting a block size limit as high as 2 GB. This contentious split caused extreme volatility in hash power and further divided the community.

Bitcoin SV has not gained broad support in the crypto industry. Its limited adoption is mainly due to governance and technical vision issues.

Conclusion

Of the many cryptocurrency projects forked from Bitcoin, Bitcoin Cash remains one of the most relevant in the crypto space. While it has not reached Bitcoin’s level of fame, BCH is accepted by numerous merchants, largely thanks to its lower fees and faster confirmations.

However, BCH’s larger block sizes raise legitimate concerns over network security. Bitcoin is still regarded as the most secure blockchain. As the most popular and widely adopted cryptocurrency, Bitcoin offers greater liquidity and market penetration than BCH, impacting BCH’s utility as a global medium of exchange. Despite these challenges, Bitcoin Cash stands as a meaningful alternative, offering unique value in scalability and accessibility for everyday transactions.
