Bitcoin Cash (BCH) is preparing for a pivotal network upgrade scheduled for May 15, 2025 — a hard fork that will expand the block size to 32MB, significantly boosting transaction capacity and scalability. This upgrade marks one of the most ambitious enhancements in the cryptocurrency’s history, reinforcing BCH’s vision of becoming a peer-to-peer electronic cash system capable of serving billions globally. With development teams finalizing code updates and node operators upgrading infrastructure, the community is aligning toward consensus readiness.
The activation will be triggered via Median Time Past (MTP), ensuring a smooth and decentralized transition. As excitement builds, stakeholders recognize this moment as more than just a technical upgrade — it's a strategic leap toward mass adoption, lower fees, and enhanced functionality.

Why the 32MB Block Size Matters
The increase from the previous limit to 32MB blocks positions Bitcoin Cash as a high-throughput blockchain, capable of processing thousands of transactions per second under optimal conditions. This scalability addresses one of the core limitations faced by other major cryptocurrencies like Bitcoin (BTC), where network congestion often leads to high fees and slow confirmations.
Current data shows that average BTC transaction fees are over 10.73 times higher than those on the BCH network. With larger blocks, BCH can maintain ultra-low fees even during peak usage, making microtransactions feasible and accessible — especially in developing economies where cost efficiency is critical.
Moreover, ample block space ensures long-term sustainability. By allocating sufficient room for transaction growth over the next several years, the network avoids frequent upgrades and reduces pressure on miners and developers to constantly optimize for space.
This expansion also strengthens decentralization. With more capacity, users are less likely to rely on off-chain scaling solutions or centralized payment processors, preserving the on-chain, trustless nature of peer-to-peer value transfer.
Tokenization and Smart Contract Capabilities
Beyond block size, this hard fork introduces powerful new features that expand BCH’s utility far beyond simple payments. Developers are now able to leverage enhanced OP_Codes and an expanded OP_Return field, unlocking support for tokenization and basic smart contracts directly on the BCH blockchain.
Unlike platforms requiring separate layers or sidechains, BCH enables native creation of representative assets — commonly known as colored coins — without relying on external ecosystems like Ethereum or dedicated token platforms. This means developers can issue digital representations of real-world assets such as:
- Stocks and bonds
- Precious metals
- Real estate titles
- Commodities
- Virtual goods and collectibles
These tokens operate securely within the existing BCH protocol, benefiting from its speed, low cost, and robust security model.
Additionally, smart contract functionality allows for programmable transactions. For example, users could set up self-executing agreements that automatically distribute BCH to beneficiaries at a future date — ideal for estate planning, inheritance distribution, or time-locked savings.
This move brings Bitcoin Cash closer to being a versatile financial platform while maintaining its core principle: simplicity and accessibility for everyday users.

Preparing for the Hard Fork: Node Readiness and Client Support
As of now, the global BCH network consists of over 1,762 nodes across 42 countries, with strong participation from major client implementations. The majority of these nodes run Bitcoin ABC, which currently holds 62% market share among BCH clients.
Encouragingly, more than 58% of Bitcoin ABC nodes have already upgraded to version ABC 17, which includes all necessary protocol changes for the May 15 fork. Other key clients are also on track:
- Bitcoin Unlimited (BU) 1.3.0.0 has been released and supports the upcoming consensus rules, including 32MB blocks, extended OP_Return data, and new opcodes.
- Bitcoin XT Cash has updated its full-node implementation to accommodate the increased block size.
- The Parity development team is actively integrating required changes, signaling broad ecosystem support.
This widespread coordination reflects lessons learned from past upgrades, particularly the successful implementation of the Difficulty Adjustment Algorithm (DAA) update and Base32 address serialization in previous cycles.

What Comes After May 15? Future Roadmap for BCH
The May 2025 upgrade is not an endpoint — it's a foundation for further innovation. Development teams are already exploring advanced features to enhance usability and performance:
- UTXO Delegation (Bitcoin ABC): A proposed mechanism allowing users to delegate transaction validation rights without transferring ownership of funds — useful for lightweight clients and mobile wallets.
- Improved DAA with PID Control (ABC & XT collaboration): A next-generation difficulty adjustment algorithm using Proportional-Integral-Derivative (PID) control theory for faster response to hash rate fluctuations, improving block time consistency.
- Graphene Block Propagation (BU Team): An experimental method to reduce bandwidth usage during block transmission, increasing efficiency and supporting faster synchronization.
- Binary Contracts via OP_Data (BU): Enabling signature verification within scripts for more complex conditional logic, paving the way for advanced smart contract use cases.
These initiatives demonstrate a clear trajectory: Bitcoin Cash is evolving into a scalable, feature-rich blockchain while staying true to its original mission — fast, cheap, and reliable digital cash.
Frequently Asked Questions
Q: What is the exact date and time of the BCH hard fork?
A: The hard fork is scheduled for May 15, 2025, activated via Median Time Past (MTP) once the network median time exceeds the threshold. No specific clock time is enforced, but it typically occurs around 12:00 UTC.
Q: Will there be a new coin created after the fork?
A: No official plans exist for a chain split or new token distribution. The upgrade is widely supported across major clients, minimizing the risk of a contentious fork.
Q: Do I need to take any action if I hold BCH?
A: Most wallet providers and exchanges will handle the upgrade automatically. However, if you run your own node or use a self-custody wallet, ensure your software is updated to a post-fork compatible version before May 15.
Q: How does 32MB affect transaction speed and fees?
A: Larger blocks allow more transactions per block, reducing competition for space. This typically results in faster confirmation times and lower fees, even during high demand.
Q: Can I create my own tokens on BCH after this upgrade?
A: Yes — with expanded OP_Return capacity and re-enabled Satoshi opcodes, developers can now build token issuance protocols and simple smart contracts directly on the BCH chain.
Q: Is Bitcoin Cash moving away from its original purpose?
A: No. While new features add functionality, the core goal remains unchanged: to serve as sound money and efficient peer-to-peer electronic cash. Enhancements aim to support broader use cases without compromising decentralization or simplicity.
