Bitcoin Cash: The History of Its Emergence, BCH Technology, Risks and Opportunities for Investors

Bitcoin Cash (BCH) is one of the most well-known cryptocurrencies that emerged after a split within the Bitcoin community. The project arose from a dispute over what a "digital cash" should be: a fast and cheap payment tool for everyday transactions or an asset primarily used for value preservation.

• Bitcoin Cash resulted from an ideological conflict surrounding the future of Bitcoin: BCH supporters bet on "electronic cash" for regular payments.
• A language called CashScript was created for the BCH ecosystem: it allows for writing compact smart contracts without overloading the global network.
• CashShuffle and CashFusion provide users with voluntary privacy tools by mixing coins from different participants, making it harder to trace transaction histories.

How Bitcoin Cash Emerged

By 2017, Bitcoin faced a capacity limitation. The 1 MB block size could no longer handle the growing number of transactions: the transaction queue increased, fees rose, and confirmations took longer.

Within the community, two approaches formed. One side supported SegWit and further scaling through the Lightning Network. The other insisted on directly increasing the block size to process more transactions directly on the main network.

A compromise could not be reached. On August 1, 2017, a hard fork occurred: part of the nodes switched to new rules allowing blocks of up to 8 MB. Thus, the Bitcoin Cash network was born. BTC holders at the time of the split automatically received an equivalent amount of BCH, and no ICO was conducted.

From Large Blocks to Adaptive Limit

The technical architecture of BCH significantly changed after its launch. On May 15, 2018, the fixed block limit was increased to 32 MB. This was a continuation of the project's core idea: to scale the network by increasing the capacity of the main chain.

The next important milestone occurred on May 15, 2024, when the network activated ABLA --- Adaptive Blocksize Limit Algorithm. After this, BCH abandoned the manually set fixed block size.

Now, the maximum size is calculated automatically for each block based on the actual load on the network. If the number of transactions sharply increases or a spam attack begins, the limit smoothly expands in real-time, reducing the risk of queues and spikes in fees. When the load decreases, it returns to the base level.

This mechanism allows Bitcoin Cash to develop on-chain scaling without new contentious hard forks. Against this backdrop, the difference with Bitcoin became even more pronounced: Bitcoin solidified its role as "digital gold" and an asset for capital preservation, while BCH continues to position itself as "electronic cash" for fast and inexpensive payments within the network.

The Split of BCH and the Emergence of BSV

The history of Bitcoin Cash did not end with a single split. On November 15, 2018, a new split occurred within the BCH community. Craig Wright and Calvin Ayre's group launched Bitcoin Satoshi Vision (BSV), proposing an even more radical approach --- increasing the block size to 128 MB.

This episode demonstrated how controversial decisions are made in decentralized networks. Miners and nodes effectively vote on the rules they are willing to follow. If there is no consensus, a single network can split into independent chains.

Mining BCH and Network Security

Bitcoin Cash uses the same Proof-of-Work algorithm as Bitcoin --- SHA-256. This makes BCH compatible with the existing ASIC infrastructure: miners can switch their equipment between BTC and BCH, choosing the more profitable direction.

An independent industry of devices specifically for BCH has not emerged. The same ASIC miners are used for mining, including Bitmain Antminer and similar solutions. The power is redistributed between Bitcoin and Bitcoin Cash pools depending on profitability.

From a security perspective, BCH has a vulnerability: the total hash rate of the network is only a fraction of Bitcoin's hash rate. Theoretically, this increases the risk of a 51% attack, meaning the concentration of computational power in a single entity. In practice, such an attack would require significant costs and create serious reputational consequences, while the network itself has mechanisms for rapid response.

To adapt to fluctuations in hash rate, the DAA --- Difficulty Adjustment Algorithm is used. It recalculates the difficulty for each block based on a moving average of previous blocks. This helps the network adjust more quickly to miner migration between BTC and BCH.

Tokenomics of Bitcoin Cash

BCH inherited the basic emission model of Bitcoin. The maximum supply is capped at 21 million coins, and this value is hardcoded.

The reward for miners is halved every 210,000 blocks, or approximately every 4 years. After the halving in April 2024, the block reward was reduced to 3.125 BCH. The next halving is expected in April 2028.

As of September 2026, there were just over 20 million BCH in circulation --- more than 95.5% of the maximum emission volume. Most of the coins have already been mined, and the annual supply growth is less than 1%.

For miners, this model creates additional pressure. The capitalization of BCH is significantly lower than that of Bitcoin, and halvings reduce the block reward. Therefore, the hash rate of Bitcoin Cash is more volatile: after a reward reduction, some miners may temporarily leave the network until the difficulty adjusts.

Technological Updates and Smart Contracts

CashTokens

On May 15, 2023, one of the most significant updates --- CashTokens --- was introduced in the Bitcoin Cash network. This is a native protocol extension built directly into the network rules. It allows for the issuance of tokens and the launching of simplified smart contracts on the BCH blockchain without third-party overlays.

Wallets use special payment addresses, which reduces the risk of compatibility errors. The update also reduced the average transaction size and opened up possibilities for regular payments, derivatives, and crowdfunding on the main chain.

CashScript

CashScript is a high-level smart contract language created specifically for Bitcoin Cash. Unlike platforms with a full virtual machine, such as Ethereum, the architecture of BCH avoids bloating the global state of the network.

Contracts in this model remain compact and do not force nodes to perform redundant computations. This approach helps maintain low fees and high transaction processing speeds.

CashFusion and CashShuffle

CashShuffle and CashFusion are voluntary tools for enhancing privacy. CashShuffle uses a CoinJoin approach: coins from multiple users are mixed, making it harder to link inputs and outputs of a specific transaction.

CashFusion combines funds into large joint transactions and further complicates the analysis of coin movement. Both solutions are used at the user's discretion, unlike cryptocurrencies where anonymization is built in as a mandatory feature.

DeFi and Stablecoins on CashTokens

After the launch of CashTokens, DeFi services began to emerge in the BCH ecosystem. One notable example is the Moria protocol with the stablecoin MUSD, backed by BCH collateral.

Moria uses automated collateral management and oracles to assess the value of the collateral. In 2025-2026, the project continued to be mentioned in ecosystem news as a working example of native DeFi based on CashTokens.

Upgrades in 2025-2026

The development of the network continues through planned updates. The May 2026 upgrade, named Layla, implements high-performance BigInt arithmetic and optimized limits for the virtual machine. This expands the capabilities of on-chain smart contracts for BCH and demonstrates that the protocol remains in an active technical development phase.

Practical Applications of BCH

The idea behind Bitcoin Cash revolves around fast, cheap, and accessible payments without intermediaries. This distinguishes BCH from Bitcoin, which has primarily established itself as a store of value.

However, the actual volumes of everyday BCH usage are still limited, especially in the face of traditional payment systems and stablecoins. Nevertheless, the technical foundation for such scenarios is laid within the network.

For transfers, users only need to install a compatible wallet, such as Wallet, that supports the CashAddr address format. Thanks to increased throughput, the network typically does not experience congestion, and fees are just fractions of a cent.

It is important to note that BCH addresses in the CashAddr format are incompatible with BTC addresses. Sending funds to another network may result in their loss.

BCH is accepted through payment processors, QR codes, and directly at points of sale. The coin is integrated into e-commerce platforms and is used for international transfers. The level of retail acceptance varies significantly by region.

Key Risks of Bitcoin Cash

• High price volatility makes BCH a risky asset for conservative strategies.
• In the payment niche, Bitcoin Cash competes with second-layer solutions for Bitcoin and specialized payment blockchains.
• The hash rate of BCH is lower than that of Bitcoin, thus the theoretical vulnerability to concentration power attacks is higher.
• The history of internal conflicts, including the split with BSV, may be perceived as a sign of management instability.
• Regulatory uncertainty could affect the liquidity of BCH and the legal status of operations with this asset.

BCH's Position in the Crypto Market

By market capitalization, Bitcoin Cash consistently remains among the largest cryptocurrencies, although its ranking position changes. At the time of preparing this material, BCH ranked 17th.

Current data on price, capitalization, and market dynamics should be viewed in aggregators that update metrics in real time.

Conclusion

Bitcoin Cash is an example of how ideological disputes within the crypto community can lead to the emergence of an independent network with its own logic of development. BCH has bet on large blocks, low fees, direct on-chain payments, and expanded capabilities through CashTokens.

The future prospects of the project will depend on how in-demand the payment and smart contract capabilities embedded in the protocol turn out to be, as well as whether the network can continue its planned technical modernization, as is happening with the upgrades in 2025-2026.
