Abstract

Purpose – The study aims to incorporate private Blockchain technology in the procurement process for the supply office. The procurement process includes the canvassing, purchasing, delivery, and inspection of items, inventory, and disposal. The Blockchain-based system includes a distributed ledger technology, peer-to-peer network, Proof-of-Authority consensus mechanism, and SHA3-512 cryptographic hash function algorithm. This will ensure trust and proper accountability to the custodian of the property while safeguarding sensitive information in the procurement records.

Method – The extreme prototyping model will be used as a software development life cycle. It is mostly used for web-based applications and has increased user involvement. The prototype version of the system allows the users to get a better understanding of the system being developed. It also reduces time and cost, has quicker user feedback, missing and difficult functions can be recognized, and confusing processes can be addressed at an early stage.

Conclusion – The implementation of a private Blockchain technology has increased privacy, enhanced security, improved efficiency, and reduced complexity over traditional Blockchain networks. The use of SHA3-512 as a cryptographic hash function algorithm is much faster than its predecessors when cryptography is handled by hardware components. Furthermore, it is not vulnerable to length extension attacks making it reliable in terms of security of data.

Recommendations – The study recommends the use of private Blockchain-based technology with the procurement and asset management system in the supply office. The procurement records will be protected against tampering using this technology. This will promote the trust and confidence of the stakeholders.

Practical Implications – The implementation of Blockchain technology in developing a system served as advancement and innovation in terms of securing data.
