Bitcoin Cash (BCH)
BitcoinCash 2025 Upgrade: VM-Limits and BigInt
Improved Smart Contracts On Bitcoin Cash
With the introduction of CashTokens in 2023, Bitcoin Cash (BCH) (re-)enabled Bitcoin’s smart contracts, ushering the blockchain into a new era of decentralized financial innovation.
Today, numerous developers are building permissionless financial projects, such as fungible tokens (FTs), non-fungible tokens (NFTs), decentralized exchanges (DEXs), prediction markets (PMs), and a broader permissionless financial ecosystem on CashTokens BCH.
The 2024 ABLA upgrade presented a solution Satoshi himself would have found invaluable in 2010, when debating with Hal Finney the need for a 1MB block size limit.
Blocksize and scaling no longer demands unproductive and heated discussions. Instead, ABLA automates the scaling process, allowing resources to be redirected toward more efficient innovations.
The 2025 upgrade proposals build upon these foundations by further optimizing security and enhancing smart contract capabilities of Bitcoin Cash.
These proposals are gaining widespread support from the community, with many development teams and stakeholders approving them:
- CHIP-2024–07 BigInt: High-Precision Arithmetic for Bitcoin Cash
- CHIP-2021–05 VM Limits: Targeted Virtual Machine Limits
2025 promises another exciting upgrade for BCH, so let’s delve into some of the details of these new enhancements.
The 2025 BCH Upgrade
The community is signaling strong support for both CHIPs (VM Limits & BigInt), but what distinct benefits will they bring?
Both upgrades enhance smart contract capabilities, boost efficiency, lower costs for developers and end-users, and improve overall security.
These new BCH smart contract features will have a significant impact on development and usage, with long-lasting effects across the ecosystem.
BigInt simplifies smart contract development, reduces the size of contract-based transactions, and lowers storage and bandwidth requirements for miners, ultimately decreasing transaction fees for contract users.
VM Limits, working alongside BigInt, increases the efficiency and security of smart contracts on Bitcoin Cash, unlocking additional use cases such as zero-knowledge proofs.
Moreover, VM Limits lays the groundwork for quantum-proof security, addressing the potential future threat quantum technology poses to the cryptography currently protecting Bitcoin’s code and blockchain systems.
Benefits
VM Limits: Maximum Efficiency
- Reduced cost for development and audits
- Improved Security And Competitiveness
- Enables AMMs, DEXs, Stablecoins, Lending protocols, Bridges, Dapps
BigInt: Security, Lower Cost
- Safer Contracts
- Reduced Transaction Size
Closing Thoughts
Both proposals are crucial for enhancing Bitcoin Cash’s (BCH) smart contract capabilities, a vital feature for positioning blockchains as alternative financial platforms. The upcoming 2025 upgrade will fine-tune BCH’s network by addressing previous limitations that hindered its potential.
These enhancements will significantly boost the blockchain’s efficiency and competitiveness, enabling the development of diverse financial products on the fast and efficient Bitcoin Cash platform.
From the programming perspective I’m the last one to judge as I have no coding abilities whatsoever. However, I understand the importance of fostering adoption and exploring new possibilities.
Therefore, from an economic standpoint, both upgrades promise substantial benefits for Bitcoin Cash.
Having been invited to share my views on the proposed upgrades, I wholeheartedly approve both proposals. I believe they will solidify Bitcoin Cash’s position as a key player in the broader blockchain ecosystem while offering long-term advantages.
