MST Blockchain Upgrades Testnet with Osaka-Compatible EVM Infrastructure
A major step toward a more scalable, secure, and developer-ready Layer 1

MST Blockchain has successfully upgraded its testnet infrastructure to support the Osaka upgrade, marking an important milestone in the continued evolution of the MST Blockchain network.
As an EVM-compatible Layer 1 blockchain, MST Blockchain continuously works toward improving its underlying infrastructure, developer experience, scalability, and compatibility with the broader EVM ecosystem.
The Osaka upgrade brings a new set of execution-layer improvements that strengthen the capabilities of EVM-based blockchain infrastructure. By introducing these advancements into the MST testnet environment, developers and the MST engineering team can evaluate, validate, and optimize the upgraded protocol before broader network deployment.
What Is the Osaka Upgrade?
Osaka is the EVM execution-layer component of the Fusaka network upgrade. Fusaka combines the Osaka execution-layer upgrade with the Fulu consensus-layer upgrade.
EVM's Fusaka upgrade introduced several protocol improvements focused on scaling, security, execution efficiency, and user experience. Among its key changes are PeerDAS for improved data availability scaling, transaction gas-limit protections, EVM improvements, and native support for the secp256r1/P-256 cryptographic curve.
For an EVM-compatible blockchain such as MST, incorporating Osaka-compatible execution-layer improvements provides an opportunity to keep the network aligned with the evolution of modern EVM infrastructure.
What This Means for MST Blockchain
The Osaka upgrade on MST Testnet represents more than a protocol update. It is part of MST Blockchain's broader strategy to build a high-performance, developer-friendly and enterprise-ready Layer 1 infrastructure.
MST Blockchain currently operates as a public, EVM-compatible Layer 1, with a focus on high throughput, low-cost transactions and enterprise applications across areas such as fintech, supply chain, digital identity and tokenization.
The upgraded testnet provides an environment for:
Testing Osaka-compatible EVM behaviour
Validating smart-contract compatibility
Evaluating execution-layer changes
Testing transaction behaviour under updated protocol rules
Identifying compatibility issues before production deployment
Improving developer tooling and infrastructure
Preparing the MST ecosystem for future protocol improvements
Key Areas of the Osaka Upgrade
1 Improved EVM Execution
The Osaka upgrade introduces several execution-layer changes designed to make the EVM more robust and predictable.
For MST Blockchain, testing these changes provides developers with an opportunity to validate how existing and new smart contracts behave under the upgraded execution environment.
This is particularly important for an EVM-compatible Layer 1 because developers expect familiar EVM development tools, Solidity-based contracts and established smart-contract patterns to continue working reliably.
2 Transaction Gas-Limit Protection
One of the Osaka/Fusaka changes introduces a cap on the amount of gas that a single transaction can consume.
This provides an additional layer of protection as networks increase their block-level capacity and helps prevent a single transaction from disproportionately consuming network resources. EVM's Fusaka specification sets this transaction limit at approximately 16.7 million gas units.
For MST, testing this behaviour on testnet allows the network to evaluate complex transaction workloads while maintaining predictable execution characteristics.
3 New CLZ EVM Opcode
Osaka also introduces the Count Leading Zeros (CLZ) opcode.
CLZ enables smart-contract execution environments to perform certain bit-level operations more efficiently, giving developers and smart-contract languages an additional low-level primitive.
Testing this capability on MST Testnet helps ensure compatibility with applications and tooling that may make use of newer EVM functionality.
4 Enhanced Cryptographic Capabilities
Another major improvement associated with Fusaka is native support for secp256r1 (P-256) cryptographic verification.
This is particularly relevant to modern authentication technologies such as passkeys, WebAuthn and device-native security mechanisms. EVM's implementation is intended to make these authentication approaches easier to use within smart-contract environments.
For enterprise applications, this opens interesting possibilities around authentication, identity and secure transaction signing.
5 Preparing for the Next Generation of EVM Applications
Protocol upgrades are not only about improving the underlying blockchain. They also create new possibilities for developers.
With Osaka-compatible infrastructure being tested on MST, developers can experiment with:
Smart Contracts DeFi Tokenization Enterprise Applications Digital Identity Payments Web3 Applications
The objective is to provide developers with infrastructure that evolves alongside the wider EVM ecosystem.
Why Testnet First?
MST Blockchain's decision to implement the Osaka upgrade on testnet provides an important validation stage before production deployment.
A testnet environment allows the engineering and developer community to test:
Protocol → Smart Contracts → Transactions → Tooling → Applications → Network Stability
This approach reduces deployment risk and provides valuable feedback from developers, validators and ecosystem participants.
What Developers Can Expect
The upgraded MST testnet creates an opportunity for developers to begin evaluating their applications against the updated EVM environment.
Developers can test:
Solidity smart contracts
EVM-compatible applications
Transaction execution
Gas-intensive operations
Wallet integrations
Developer tooling
Protocol interactions
Enterprise application workloads
MST Blockchain already supports common EVM development tools such as MetaMask, Remix, BridgeKey, allowing developers familiar with the EVM ecosystem to work with MST with minimal changes.
A Step Forward for MST's Infrastructure Roadmap
The Osaka upgrade is part of MST Blockchain's larger infrastructure roadmap. MST is building a Layer 1 ecosystem focused on combining performance, EVM compatibility, enterprise infrastructure and real-world applications.
The network currently supports applications and infrastructure spanning areas including:
Tokenized Real Estate Supply Chain Digital Identity & KYC Healthcare Records Land Records Payments Enterprise Workflow Automation Digital Asset Exchange Loyalty & Rewards Gaming Education Credentials
The Osaka-compatible testnet upgrade strengthens the foundation on which these applications can continue to evolve.
What's Next?
The MST Blockchain team will continue testing and optimizing the Osaka-compatible implementation on testnet. The next stages will focus on:
Testing → Developer Feedback → Performance Validation → Compatibility Testing → Security Review → Mainnet Readiness
Only after comprehensive validation will the network consider broader deployment.
Building an EVM Infrastructure Ready for What's Next
Blockchain infrastructure cannot remain static. As the EVM ecosystem evolves, Layer 1 networks need to continuously improve their execution environments, developer tooling, security and scalability.
With the Osaka upgrade now being tested on MST Blockchain Testnet, MST takes another step toward its vision of building high-performance, EVM-compatible infrastructure for the next generation of Web3 and enterprise applications.
The upgrade is on testnet. The testing continues. The infrastructure keeps evolving.
