Distributed nodes tamper-proof: SHA-256 code integrity.
Día 03 de la serie técnica wFabricSecurity Open Source. ¿Cómo sabes que el worker que envía transacciones al blockchain no fue alterado en disco? wFabricSecurity verifica la integridad SHA-256 del código antes de ejecutar.

The article discusses wFabricSecurity, an open-source solution for ensuring the integrity of code in Hyperledger Fabric environments. It verifies the SHA-256 hash of critical files before execution, detecting any tampering or alterations. The implementation involves registering files, such as worker_logic.py and contract_gateway.py, with a specific version, and verifying the code integrity using a try-except block.
The solution has been tested and verified in Hyperledger Fabric environments and is compatible with Python 3.10+. wFabricSecurity is available on GitHub and PyPI, developed by William Steve Rodríguez Villamizar of Wisrovi.
