The upcoming Bitcoin Cash (BCH) hard fork has sparked widespread discussion across the cryptocurrency community. As one of the most anticipated blockchain events of the year, it brings technical upgrades, ideological clashes, and potential market shifts. Whether you're a long-term holder, an investor, or simply curious about blockchain evolution, understanding this hard fork is essential.
This article breaks down everything you need to know—from the core changes in the protocol and the battle between major factions, to what it means for your holdings and the broader crypto ecosystem.
What’s Changing in the BCH Hard Fork?
At its core, the Bitcoin Cash hard fork introduces several key technical upgrades aimed at improving network efficiency, security, and programmability. These changes include:
- Removal of topological transaction ordering restrictions, replaced with enforced canonical transaction ordering for better predictability.
- Activation of OP_CHECKDATASIG and OP_CHECKDATASIGVERIFY — powerful new opcode functionalities that enable smart contract capabilities on the BCH chain.
- Implementation of minimum transaction size rules to prevent spam and dust attacks.
- Enforcement of “push only” rule for scriptSig, enhancing script security by limiting executable code in signatures.
- Introduction of “clean stack” rules, ensuring scripts leave a clean execution environment, reducing vulnerabilities.
These updates are part of a broader vision to make Bitcoin Cash more scalable and functionally rich—paving the way for decentralized applications similar to those on Ethereum.

The Battle Behind the Code: Bitcoin ABC vs. Bitcoin SV
While technical improvements are central, the real drama lies in the ideological divide within the BCH community. Two major factions have emerged, each with competing visions for the future of Bitcoin Cash.
Bitcoin ABC – Building a Smart Contract-Ready Chain
Led by Bitcoin ABC, a development team historically backed by Bitmain, this faction advocates for expanding BCH's functionality beyond simple payments. Their goal is to transform BCH into a robust infrastructure layer capable of supporting:
- Oracle integrations
- Cross-chain atomic swaps
- Lightweight smart contracts
By enabling opcodes like OP_CHECKDATASIG, they aim to unlock interoperability and expand use cases—similar to Ethereum’s early growth trajectory.
Bitcoin ABC aligns with the official bitcoincash.org roadmap and has gained support from major platforms including Coinbase and Roger Ver’s Bitcoin.com. Binance also signaled indirect support by linking to Bitcoin ABC’s GitHub repository in its official announcement.
Bitcoin SV – Returning to “Original Bitcoin” Principles
On the opposing side is Bitcoin SV (Satoshi Vision), led by Dr. Craig Wright—often referred to in the community as "Craig Wright" or controversially, "the man who claims to be Satoshi Nakamoto."
SV stands for "Satoshi Vision," and its proponents believe BCH should remain focused on being peer-to-peer electronic cash. They argue against expanding scripting capabilities, fearing increased complexity and potential misuse.
Their primary technical proposal? Increase block sizes up to 128MB—far beyond the current 32MB limit—to prioritize high-volume transaction processing and data storage.
Support for BSV comes largely from mining power, notably Coingeek, one of the largest BCH miners. This gives them significant influence over which chain might survive post-fork.
Will There Be a New Token? What Holders Need to Know
Unlike previous upgrades, this hard fork carries a real risk of chain split due to irreconcilable differences between ABC and SV.
If no consensus is reached by the fork date, two separate chains could emerge:
- BCH ABC (supported by exchanges and developers favoring innovation)
- BCH SV (backed by miners advocating for maximalist scaling)
For users holding BCH at the time of the fork, this likely means a 1:1 airdrop of the new SV token—just as happened during the original BTC/BCH split in 2017.
However, not all exchanges will support both chains. Some may choose only one, based on stability, community support, or technical viability.

Exchange Support and Market Reactions
Market sentiment has responded strongly to the fork news. In just three days—from November 2 to November 5—BCH price surged from $425 to $591, a nearly 40% increase, reflecting investor anticipation and speculative activity.
Major exchanges have taken clear stances:
- Coinbase announced support for the official Bitcoin Cash roadmap (i.e., Bitcoin ABC), while acknowledging the possibility of multiple valid chains post-fork.
- Binance aligned with Bitcoin ABC through documentation links and public statements.
- Bitcoin.com, run by early BCH advocate Roger Ver, openly backs Bitcoin ABC.
This institutional backing strengthens ABC’s position—but doesn’t guarantee dominance. Mining hash rate will play a crucial role in determining which chain remains secure and functional after the split.
Frequently Asked Questions (FAQ)
Q: When is the BCH hard fork happening?
A: The hard fork is scheduled to activate at block height 556767, expected around November 15, 2025. This date marks the point when nodes running updated software will begin enforcing new consensus rules.
Q: Do I need to take action if I hold BCH?
A: If your BCH is stored on a supported exchange like Coinbase or Binance, no action is required—the platform will handle the split and distribute any new tokens accordingly. However, if you hold private keys (e.g., in a wallet), you may need to prepare for potential chain splits and ensure compatibility with both networks.
Q: Could one chain become more valuable than the other?
A: Yes. Post-fork value depends on multiple factors: exchange listings, merchant adoption, developer activity, and miner support. Historically, the chain with stronger ecosystem backing tends to retain higher market value.
Q: Is Bitcoin SV considered a legitimate continuation of BCH?
A: While Bitcoin SV claims ideological purity, it remains controversial—especially due to Craig Wright’s disputed identity claims. Legitimacy in crypto is ultimately determined by decentralized consensus, not marketing narratives.
Q: Are there risks involved in the fork?
A: Yes. Risks include replay attacks (transactions valid on both chains), wallet incompatibility, and temporary price volatility. Always verify chain identifiers (like ticker symbols) before trading or transferring funds post-fork.
Q: How can I stay updated on developments?
A: Follow official client repositories (Bitcoin ABC, Bitcoin SV), monitor announcements from major exchanges, and consult trusted blockchain analytics platforms for real-time hash rate distribution.

Final Thoughts: Evolution or Fragmentation?
The BCH hard fork represents more than just a technical upgrade—it's a referendum on what decentralized governance looks like in practice. It highlights how philosophical differences can lead to network splits, even within communities built on shared origins.
While Bitcoin ABC pushes for innovation and expanded utility, Bitcoin SV champions simplicity and scalability through massive blocks. Neither side has a clear monopoly on "Bitcoin ideals"—but only time will tell which vision gains lasting traction.
For investors and users alike, staying informed is key. Understand the implications of chain splits, monitor exchange policies, and protect your private keys. In the world of blockchain, change isn't just inevitable—it's foundational.
