#Blockchain is used by India's HPCL state refinery to validate purchase orders.

One of the biggest oil and gas firms in #India , Hindustan Petroleum (#HPCL ), a state-run refiner, is introducing a blockchain technology to facilitate automatic purchase order (PO) verification.

HPCL and Zupple Labs have joined forces to incorporate #Zupple Labs' blockchain-based digital credentialing technology, known as LegitDoc, into HPCL's purchase order system. This technology allows HPCL to issue digital purchase orders to its vendors without the need for manual verification. For third-party verifiers, this initiative offers an automated means to directly confirm the legitimacy of purchase orders on the HPCL website.

An HPCL spokesperson explained that this implementation streamlines the verification of HPCL's purchase orders for external parties. It involves integrating blockchain into HPCL's internal electronic purchase order system, resulting in tamper-evident and verifiable purchase orders. These orders are then sent to vendors, who can share them with third parties. Any third-party verifier can use the HPCL vendor portal verification application to confirm the authenticity of these purchase orders.

The HPCL representative revealed that the collaboration with Zupple Labs on this blockchain project has spanned six months, and HPCL has successfully developed the blockchain purchase order system. They anticipate making this system officially available to vendors later this month.
