In just over three weeks, the Bitcoin Cash (BCH) network will undergo a significant upgrade, increasing its block size to 32MB and integrating new protocol functionalities. The community is steadily preparing for this consensus-driven change, with developers releasing updated code and users upgrading full nodes.
BCH Network to Execute Historic Block Size Expansion
On May 15, 2018, at approximately 12:00:00 UTC, the Bitcoin Cash network will activate its upgrade using the Median Time Past (MTP) method. This 32MB block size increase marks the largest scalability enhancement in the cryptocurrency space, enabling:
- Higher transaction throughput for global adoption.
- Ultra-low fees, making BCH 10.73x cheaper than BTC transactions.
- Long-term capacity to accommodate future demand.
Beyond Block Size: New Features
The upgrade also introduces:
- Re-enabled OP_Codes for smart contract functionality.
- Expanded OP_Return data size, enabling tokenization (e.g., colored coins for assets like bonds, stocks, or commodities).
- Decentralized applications (DApps) and programmable contracts on the BCH chain.

Full Node Upgrades in Progress
As of now:
- 62% of BCH nodes run Bitcoin ABC (v17), already upgraded for the May 15 changes.
- Other clients (Bitcoin Unlimited, Parity, XT) are releasing compatible updates.
Key Client Updates:
| Client | Status |
|--------------|---------------------------------|
| Bitcoin ABC | 58% nodes upgraded (v17) |
| Bitcoin XT | Supports 32MB blocks + CashAddr |
| Bitcoin Unlimited | Ready for consensus changes |
Future Innovations on the Horizon
Post-upgrade, BCH developers are exploring:
- UTXO commitments for lighter nodes.
- Graphene block propagation (faster syncing).
- Improved DAA algorithms for mining stability.
FAQ Section
Q: Why increase the block size to 32MB?
A: To ensure scalability, lower fees, and support mass adoption without congestion.
Q: Will this upgrade affect transaction speed?
A: No—it enhances capacity while maintaining BCH’s fast settlement times.
Q: How does tokenization work on BCH?
A: Expanded OP_Return allows creating tokens representing real-world assets (e.g., gold, equities).
Final Thoughts
The May 15 upgrade solidifies Bitcoin Cash as a scalable, low-cost, and versatile blockchain. With smart contracts and tokenization, BCH is poised to rival Ethereum in utility while retaining Bitcoin’s core principles.
