HPCL Partners with Zupple Labs for Blockchain PO Verification

Hindustan Petroleum (HPCL), one of India’s leading oil and gas companies, is launching a blockchain system to automate the purchase order (PO) verification process.

The blockchain software company Zupple Labs and HPCL have partnered to incorporate HPCL’s blockchain-based digital credentialing technology into the purchase order system, the companies announced in a joint statement.

HPCL can issue digital POs to its vendors without manually verifying the PO requests thanks to Zupple Labs’ LegitDoc verification technology.

From the perspective of a third-party verifier, the initiative provides the capability to directly and automatically verify the validity of POs on the HPCL website.

“The implementation helps to automate the verification of HPCL POs with external parties,” according to a spokesperson for HPCL. “This works by integrating the blockchain system with HPCL’s internal e-PO and generates tamper-evident, verifiable POs,” a representative explained,.

These purchase orders will be sent to vendors, who may then share them with third parties. On the HPCL vendor portal verification application, any third-party verifier can directly validate these POs.

According to a spokesperson for HPCL, the company has collaborated with Zupple Labs for the past six months on the blockchain initiative. “HPCL has completed construction of the blockchain PO system, and the same facility will be made available to vendors within this month,” a representative said.

The HPCL spokesperson stated that the blockchain-based PO system has been implemented on both private and public blockchains.

According to Neil Martis, co-founder and business lead at Zupple Labs, the PO verification system has incorporated “two parallel blockchains” as settlement layers, namely the public Near blockchain and the private Hyperledger Fabric blockchain.

Martis remarked that the latter was an element of HPCL’s business continuity and disaster recovery strategy. As of mid-October 2023, according to Zupple Labs, HPCL had issued 3,000 purchase orders through the facility.
