PROFILE
Bar Haim
Barha contributed to the hyperledger-labs/fabric-token-sdk repository by engineering issuer-aware transfer and redemption features for token workflows. Over two months, Barha enhanced the core token logic to propagate issuer identity through transfer actions and redemption flows, integrating issuer signing and signature verification to strengthen security and traceability. The work included the introduction of issuer fields in Protocol Buffers definitions, updates to Go-based backend logic, and comprehensive unit and integration testing, including scenarios for zero-knowledge token redemptions. These changes improved governance and auditability of token operations, laying a foundation for more reliable and business-aligned blockchain tokenization processes.

Mar 1, 2025March 2025: Delivered FabToken Redeem with Issuer Signing and Protobuf Enhancements for hyperledger-labs/fabric-token-sdk. Implemented issuer identity in TransferAction protobuf, integrated issuer signing into the redeem flow, and added verification of issuer signatures during redemption. Updates encompassed core token logic, tests, and SDK configurations, plus a small protobuf import cleanup for maintainability. This work enhances transfer traceability, security, and governance by enabling issuer-authorized actions and verifiable redemptions. The work was supported by four commits that implemented the changes.
