Designing Architecture Blockchain of Hyperledger Fabric for Purchasing Strategy

Hyperledger Fabric refers to a blockchain technology regulated by the Linux Foundation, which implements a blockchain network, namely the permission blockchain. The network provides a membership service concept, which means that only certain parties can transact and access data. This research will show the blockchain architecture design of the hyperledger fabric, which is designed for the purchasing strategy of recycled waste products. The design will be used to make purchases for managing distributors in buying recycled waste products from waste banks as raw materials to be processed. The traditional purchasing process using the bank as a third party will take longer and will be more expensive. Therefore, this research aims to improve data security and transparency between the authorities and direct the payment process in an instant and dramatically reduce transaction costs. Besides, this design can also be applied to any e-commerce. The method used is blockchain, which focuses on hyperledger fabric design. The position on the hyperledger fabric is only applied to the transaction processing of the hyperledger fabric. This study's results apply a design to a blockchain system using a hyperledger fabric to overcome several technical problems related to blockchains such as throughput, scalability, and interoperability and contribute to purchasing strategies
