Development of a Secure Blockchain-Based B2B Commodity Trading Platform

The client faces challenges in maintaining secure, transparent, and efficient trading operations. There is a need to develop a platform that consolidates negotiations, communication, and contract signing, while ensuring confidentiality and reducing risks of fraud. The client also requires a resilient infrastructure that supports dynamic business process improvements and strict security policies.

A mid-sized commodities trading firm seeking to modernize its trading processes with integrated blockchain smart contracts, secure communication channels, and a scalable marketplace platform.

• Implement a comprehensive marketplace for B2B commodities trading with integrated communication features.
• Ensure all negotiation, communication, and contract signing activities occur exclusively within the platform to enhance security and minimize fraud risk.
• Develop a blockchain-based smart contract system for transparent, tamper-proof signing of agreements.
• Create a flexible architecture that supports continuous process updates and feature toggling without significant downtime.
• Build a microservices-based system architecture for scalability, independent deployment, and maintenance.
• Enhance data exchange performance through the use of peer-to-peer protocols such as IPFS.

• A B2B marketplace interface for listing, browsing, and trading commodities.
• Integrated communication system including internal chat, email, voice calls, and app notifications, with rules managed by administrators.
• Blockchain smart contract module for signing, storing, and verifying contracts on a decentralized ledger.
• Microservices architecture to support independent deployment, scaling, and feature toggling.
• APIs for third-party integrations such as messaging platforms and email services.
• Use of peer-to-peer protocols (e.g., IPFS) for high-bandwidth, resilient data exchange.
• Role-based access control with configurable user roles and flow-specific user journeys.

• Messaging platforms (WhatsApp, internal chat systems)
• Email services for notifications and communication
• Blockchain networks for contract signing and verification
• Third-party services for user authentication and data storage
