PROFILE
Bar Haim
Barha contributed to the hyperledger-labs/fabric-token-sdk repository by engineering issuer-aware transfer and redemption flows for tokenized assets. Over two months, Barha implemented issuer identity propagation in the TransferAction protobuf, integrated issuer signing into both transfer and redeem operations, and enhanced verification logic to ensure issuer signatures are validated during redemption. The work included updates to core token logic, SDK configurations, and comprehensive unit and integration tests, including scenarios with nil issuers. Using Go, Protocol Buffers, and cryptographic techniques such as zero-knowledge proofs, Barha’s contributions improved the security, traceability, and governance of token transfers and redemptions within the system.

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.
