RESUMEN

A distributed and decentralised ledger system shared by a variety of users in a peer-to-peer network is defined as a blockchain. Through its decentralised approach, it makes pharmaceutical products more accessible and secure for vendors, while they can maintain and access their inventories themselves. Between a company and its suppliers, a supply chain is used to produce and distribute a specific product or service, whose efficiency is increased with its integration in the supply chain. For efficient and transparent tracking of products, blockchain will be the right choice. In view of blockchain being incorporated into the supply chain system, it solves many logistical issues that supply chains face, such as appropriate data access, ensuring data quality, and many more. This can increase the traceability of the material supply chain and improve the maintenance of the list when there are several products to be supplied. Therefore, the concept of supply chain was developed in two platforms namely, Hyperledger Fabric and Hyperledger Sawtooth. Finally, Hyperledger Sawtooth was found to be well suited for creating decentralised apps or platforms with respect to resource utilization It enables developers to separate their application domain from the core system so that business rules for apps can exist without requiring knowledge of the primary platform's underlying architecture. The proposed system shows that Hyperledger Sawtooth framework consumes lower CPU than Fabric which helps in increasing the number of transactions.
