Commonware — a modular library for blockchain system development built in Rust. The project promotes the “anti-framework” idea, offering developers not a rigid stack but a set of interchangeable primitives: consensus, cryptography, networking, storage, and execution. This approach enables the creation of custom chains and rollups tailored to specific goals — from payment networks to gaming platforms with minimal latency. Commonware has attracted major investors, including Haun Ventures, Dragonfly, and Tempo (a Stripe and Paradigm initiative), reflecting its strong technological and market potential.

Essence and Philosophy of Commonware
Commonware promotes the “anti-framework” concept — a library of modular primitives that allow developers to build their own blockchain without the constraints of a universal system. The project contrasts itself with massive ecosystems like Cosmos SDK and OP Stack, giving full control over system architecture. This is particularly valuable for teams developing specialized networks such as gaming blockchains, payment solutions, or DeFi protocols. Commonware reduces technical debt, accelerates experimentation, and enables rapid integration of new technologies while maintaining robustness and compatibility. It also embodies a philosophy of engineering freedom — every component can be understood, customized, and improved without rebuilding from scratch. This makes Commonware not merely a tool but a full design methodology for decentralized systems, proving that openness can coexist with reliability and high performance.
Architecture and Key Modules
The Commonware architecture is built in Rust and organized as a set of independent, replaceable modules. Each component can be configured separately, allowing precise adaptation to technical and business requirements. The main modules include:
- Consensus — customizable consensus layer (e.g., BFT or PoA);
- Cryptography — BLS signatures and distributed key generation (DKG);
- P2P — peer-to-peer networking with secure data transmission;
- Storage — Merkle Mountain Range (MMR)-based data structure;
- Runtime — task and transaction execution environment;
- Streaming — event and data streaming between modules.
This modular structure turns Commonware into a blockchain constructor where each layer can be swapped or upgraded without rewriting the entire system. Each module is designed for easy testing and integration with external libraries, enabling developers to combine different consensus, cryptographic, or storage layers. This architecture ensures that Commonware can serve both as a rapid prototyping environment and a foundation for production-ready, high-performance networks.
Performance and the Alto Reference Chain
To demonstrate its capabilities, Commonware introduced the Alto test chain. It serves as a practical benchmark showing how optimized modular configurations affect throughput and latency. The following table summarizes key performance metrics of Alto:
| Metric | Value | Comment |
|---|---|---|
| Block time | ≈ 200 ms | Optimized signature and propagation pipeline |
| Finalization | ≈ 300 ms | Near-instant confirmation latency |
| CPU load | −65% | Improved multi-threaded signature processing |
| Storage structure | MMR | Authenticated history without recomputation |
| Cryptography | BLS12-381 | Group signatures and verifiable aggregation |
Alto acts as a public benchmark platform for validating Commonware’s performance claims. By publishing all results transparently, the team builds trust and allows independent verification. It also demonstrates that Rust-based infrastructure can rival C++ and Go systems while offering better memory safety and fault tolerance — critical advantages for enterprise-grade blockchain development.
Use Cases and Advantages
Commonware is increasingly adopted by teams looking to move beyond generic frameworks and design tailored blockchain infrastructure. The project enables modular development — building from the ground up using precisely chosen components. This approach creates room for networks optimized for specific business or technical conditions rather than “one-size-fits-all” architecture.
Commonware targets teams with specialized needs and is applied in three primary domains:
-
Payment networks — through its partnership with Tempo (a Stripe and Paradigm initiative), the project explores low-latency, high-throughput transaction processing.
-
App-chains and rollups — developers can build independent chains without relying on OP Stack or Cosmos SDK.
-
Gaming and social applications — modular runtime architecture supports real-time interactions.
Commonware’s main strengths lie in flexibility, performance, and ease of integration into diverse ecosystems. The library is also compatible with modern DeFi protocols and security frameworks, making it a strong foundation for emerging Web3 infrastructures. The team emphasizes open-source collaboration by publishing SDKs, documentation, and reference implementations for developers worldwide.
Team, Partners, and Risks
Commonware is led by engineer Patrick O’Grady, previously a core contributor to Avalanche. Its investors include Haun Ventures, Dragonfly, and Tempo, which collectively contributed around $25 million. This financial backing enables rapid ecosystem expansion and long-term development of the library. However, the project faces competition from established frameworks and requires technically skilled teams for deployment. Despite these challenges, Commonware continues to grow, attracting developers passionate about modular, transparent infrastructure. Its focus on interoperability and open governance positions it as a potential cornerstone of next-generation Web3 engineering.
