Major Agrinet Marketplace Backend Milestone from Brazil

São Paulo, Brazil — The Network Theory Applied Research Institute (NTARI) today announced a major backend milestone for Agrinet, its decentralized agricultural marketplace initiative, following a substantial upgrade completed at the Agrinet Brazil node.

The update delivers a fully stabilized Marketplace and Wallet transaction flow, introducing a robust, auditable financial lifecycle designed for real-world trust, scalability, and migration readiness.

At the core of the release is a complete refactor of the Agrinet Marketplace backend, with the Wallet now fully integrated into transaction creation. Buyers are debited at the moment a transaction is initiated, while seller funds are securely held in escrow and released only after both parties complete a mutual rating process. Reputation scores are updated automatically as part of this lifecycle, closing the loop between commerce, accountability, and trust.

The transaction lifecycle—create → rate → escrow release—is now functioning end-to-end with proper locking and concurrency protection. Escrow remains locked until both parties fulfill their obligations, preventing premature settlement and ensuring fair outcomes.

In parallel, NTARI engineers completed a significant architectural modernization:

• Business logic was extracted into dedicated service layers

• A repository pattern was implemented to isolate data access

• Routes were cleaned and hardened with stronger validation

• AWS-specific dependencies were isolated and decoupled

• Core financial logic was migrated to MariaDB, enabling real SQL transaction control and concurrency safety

This migration includes wallet debits and credits, escrow release logic, and the reputation system—all now backed by SQL rather than distributed NoSQL side effects. The result is a modular, testable system that is ready for long-term maintenance and future database transitions.

“Because AWS synchronization had grown across multiple legacy modules, this refactor required careful untangling,” said the Agrinet development team. “While time-intensive, the progress achieved puts Agrinet on solid footing for clean SQL architecture and future PostgreSQL integration.”

Next steps include final removal of DynamoDB dependencies from remaining legacy modules, standardization of error handling, cleanup of historical code paths, and preparation for full PostgreSQL deployment.

Agrinet is part of NTARI’s broader mission to build resilient, decentralized infrastructure that supports local economies, transparent markets, and community-owned digital systems.
