Designing a Permissioned Blockchain Network for the Halal Industry using Hyperledger Fabric with multiple channels and the raft consensus mechanism
Halal Supply Chain Management requires an assurance that the entire process of procurement, distribution, handling, and processing materials, spare parts, livestock, work in process, or finished inventory to be well documented and performed fit to the Halal and Toyyib. Blockchain technology is one alternative solution that can improve Halal Supply Chain as it can integrate technology for information exchange during the tracking and tracing process in operating and monitoring performance. This technology could improve trust, transparency, and information disclosure between supply chain participants since it could act as a distributed ledger and entitle all transactions to be completely open, yet confidential, immutable, and secured. This study uses a Blockchain Network with three channels and uses raft consensus algorithm in designing web interfaces and testing their capabilities. From the web interface, there were no failures in the validity test during the invoke test and the query test. In addition, the web interface was also successfully tested to thwart the formation of a block in case of data input errors from the user. The server can also do the process as a provider of information and validator for the web interface. From the results of simulations conducted on the Blockchain Network that was made, Blockchain's transaction speed is fast and all the transaction is successfully transferred to other peers. Thus, Permissioned Blockchain is useful for Halal Supply Chain not just because it can secure transactions from some of the halal issues, but the transaction speed and rate to transfer data are very effective.
