Protocol Engineering and Layer 1 Blockchain Development

Soramitsu provides comprehensive protocol engineering services for Layer 1 blockchain development, consensus mechanism implementation, and custom chain development. As the original developer of Hyperledger Iroha, the company brings nearly a decade of experience building production-grade blockchain frameworks that power CBDCs, national payment systems, and enterprise applications serving millions of users worldwide.

Core Protocol Engineering

Services include Layer 1 blockchain development, Byzantine Fault Tolerant (BFT) consensus mechanism implementation, peer-to-peer networking architecture, cryptographic primitives implementation, and custom chain development using frameworks like Cosmos SDK, Substrate, and proprietary implementations. Soramitsu specializes in designing distributed systems that meet the demanding requirements of central banks, governments, and enterprises.

Key technical capabilities include consensus algorithm development and optimization, distributed system architecture design, cryptographic implementation and security hardening, protocol-level interoperability solutions, and blockchain performance tuning for high-throughput applications. The engineering team has deep expertise in ensuring Byzantine fault tolerance, implementing secure cryptographic protocols, and optimizing network performance.

Hyperledger Iroha Development

Soramitsu developed Hyperledger Iroha, an advanced blockchain framework contributed to the Linux Foundation's LF Decentralized Trust project. Iroha is designed for simplicity, security, and flexibility, making it ideal for enterprise applications, digital asset management, and digital identity solutions. The framework provides permissioned blockchain architecture, Byzantine Fault Tolerant consensus, rich permission model for fine-grained access control, multi-signature transaction support, and comprehensive asset management capabilities.

The company also developed Hyperledger Iroha 2, the next generation of the framework written in Rust for memory safety and performance. Iroha 2 offers significant improvements including enhanced performance capabilities, improved smart contract functionality, more flexible consensus mechanisms, and better scalability for enterprise deployments. This represents a complete redesign based on years of production experience with Iroha 1.

Production Deployments and Support

Hyperledger Iroha powers production systems including multiple CBDCs across Asia-Pacific, national payment systems like Cambodia's Bakong (serving 7 million+ users), and various enterprise blockchain applications. Its proven reliability in mission-critical financial infrastructure makes it a trusted choice for governments and enterprises requiring production-grade blockchain solutions.

As the original developer and main contributor to Hyperledger Iroha, Soramitsu provides comprehensive technical and business support for organizations implementing Iroha-based solutions. Services include architecture consulting and design, custom development and feature implementation, blockchain integration with existing systems, performance optimization and tuning, security auditing and hardening, and ongoing maintenance and support.
