Jun 1, 2025June 2025 performance summary for tvmlabs/tvm-sdk: Delivered external message source address authentication for Block Manager, enabling origin verification for Block Keepers and updating message encoding to include the new source address information. Implemented token verification key handling on the Block Processor (BP) to validate incoming messages. No major bugs fixed this month; security-focused enhancements reduce spoofing risk and improve auditability. Impact includes stronger end-to-end integrity for cross-component messaging and readiness for enterprise deployments. Technologies demonstrated include cryptographic authentication, message encoding updates, token verification key management, and secure messaging workflows.

May 1, 2025Month: 2025-05 — TVM SDK enhancements focused on reliability and secure node interaction. Delivered two features in tvmlabs/tvm-sdk: (1) Port-aware external message delivery: upgraded to TVM SDK 2.13.0 and used redirect response port to construct endpoints, improving external messaging reliability; (2) BP token support for enhanced authentication and messaging with blockchain nodes, with updated dependencies and refactored network config. Also improved client error handling and network communication to ensure connections to the specified port. Impact: reduced external message delivery failures, more robust node communication, and easier maintenance through dependency updates. Skills demonstrated: port-based routing, token-based authentication, network resilience, dependency management, and robust error handling.

Mar 1, 2025March 2025: tvmlabs/tvm-sdk delivered a key feature enabling retrieval of contract return values when sending contract messages. Updated send_message to accept an optional ABI, decoded the message body to extract outputs, and captured the contract's return value, with an SDK version bump. This enhances developer experience by providing end-to-end visibility of contract results and reduces the need for additional queries. No critical bugs fixed this month; feature-focused release with backward-compatible changes.
