Nikita Kulkarni Assoc. Professor RAIT, Navi Mumbai [email protected] Abstract – To merge the digital and physical world, we records the journey of dairy product from manufacturer to consumer. Like the milk, IoT sensors can be attached to any object entrusted to someone else for transport, wit h trackable ownership, possession, and telemetry parameters such as location, temperature, humidity, motion, shock and tilt.

The ?nal buyer can access a complete record of information s and trust that the information is accurate and complete. I.In troduction Supply chain management today is a complex endeavor . Regardless of how many Enterprise Resource Planning (ERP) solutions, work?ow tools, digital shipment tracking devices or other integrated monitoring solutions are deployed, complexities, product losses and inaccurate data management abound. No longer the responsibility of one or m ultiple players, today’s supply chain is riddled with multiple parties, multiple checkpoints and across them all – a tangled web of processes and the systems that need to properly integrate to function cohesively. The prevalence of inaccuracies, billing disputes, outright fraud and corruption, means that the whole supply chain needs to be properly audited by impartial third parties, and often.
However, imagine if t he entire supply chain could be managed electronically from raw material phase up to customer delivery, with no room for errors, and in such a way that many time -consuming weigh and checkpoints were not required anymore ? Imagine the speed at which a produc t could ?ow from A to D. Blockchain technology is mostly known in the ?nancial sector; its origins fused with those of cryptocurrencies that have relied upon its transparency and unparalleled security to underpin their success. Essentially, a decentralised, distributed digital ledger, the blockchain can be used to record transactions for anything of a value across a system of computers in such a way the no record can be changed retroactively without consensus across the entire computer system. In the ?nanci al sector, it is being explored and actively used to conduct ?nancial transactions and even manage the contracts. For the supply chain, the bene?ts supersede merely keeping accurate records: radically reducing the excessive amount of time spent on paperwor k and authorization. Currently, most of the delays on any product or materials shipments are due to these two requirements. On the blockchain, just a digital signature is needed, and the accuracy and authenticity of the digital paper trail is such that no time needs be wasted on verifying previous records.
The aspects included while developing Hyperledger fabric: 1. Blockchain Architect: Responsible for the architecture and design of the blockchain solution. 2. Blockchain User: The business user, operating in a business network. This role interacts with the Blockchain with the help of an application. They are not aware of the Blockchain.
3. Blockchain Regulator: The whole authority in a business network. Speci ?cally, regulators may require broad access to the ledger contents.
4. Blockchain Developer: The developer of applications and smart contracts that interact with the Blockchain and are used by Blockchain users.5. Blockchain Operator: Manages and monitors the Blockchain network. Each and every business in the network has a Blockchain Network operator. 6. Membership Services: Manages the di?erent types of certi?cates required to run a permissioned Blockchain.
7. Traditional Processing Platform: An existing computer system which may be used by the Blockchain to augment processing. This system may also need to initiate requests to the Blockchain. 8. Traditional Data Coordinator: An existing data system which may provide data to in?uence the behavior of smart c ontracts.
II. Proposed System Our system is a permissioned blockchain network that gets set by the organizations that intends to setup a consortium. The organizations that take part in building the Hyperledger Fabric network are called as the “members”. Each member organization in the blockchain network is responsible to setup the peers for participating in the network. All of these peers need are con?gured with appropriate cryptographic materials like Certi?cate Authority and various other information. Gi ven the task of providing a supply chain system that would connect many small businesses we want to minimize the need for expensive infrastructure, and since the target sector was dairy products we also wanted to provide a system that would be easy to lear n and use for non- technical people. Consequently we have decided to make the system available via a mobile app due to the ubiquity of mobile devices and peoples familiarity with them. We used react -native to build the app so that we could target both Android and iOS in a single app, and also have the option of turning it into a desktop web -app with minimal adjustments.
For the server- side blockchain implementation we have chosen Hyperledger Composer. Its user friendly GUI, allowed us to dive in and get started straight away, and its modeling language mapped well to our problem domain. Softwares used are: 1. Hyperledger Fabric : It is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. Intended as a fou ndation for developing solution with a modular architecture, Hyperledger Fabric allows components, like consensus and membership services, to be plug -and -play. Hyperledger Fabric leverages container technology to host smart contracts called (chain -codes) that comprise the application logic of the system. Hyperledger Fabric was initially contributed by Digital Asset and IBM, in the ?rst hackathon.
Docker : Docker is a computer progra m which performs operating -system -level virtualization, also known as “containerization”. It was ?rst released in 2013 and it is developed by Docker, Inc. It is used to run software packages called “containers”. 4.
Loopback: In telecommunications, loopback is a method used to perform transmission tests of the lines at the switching center. Loopback is a communication channel with a single endpoint. TCP/IP networks specify a loopback that allows the client software to communicate with server software on the same computer. users can specify an IP address, usually 127.0.0.1, which will point back to the ir computer’s TCP/IP network con?guration.
The range of addresses for loopback functionality is 127.0.0.0 to 127.255.255.
255. Similar to ping, the loopback enable s a user to test one’s own network to ensure the IP stack is functioning properly. 5. IPFS: IPFS stands for Interplanetary File System. At its core it is a versioned ?le system which can store ?les and track versions over time, like Git. It also de?nes how the ?les move across a network, making it a distributed ?le system, much like BitTorrent.
In combining these two properties, IPFS enables a new permanent web and augments the way we all use existing internet protocols like HTTP . III. Methodology A participant in the member Organization invokes a transaction request through a client application. Client application broadcasts the transaction invocation request s to the Endorser peer. Endorser peer checks the Certi?cate details and other records to validate the transaction. Then it executes the Chaincode (Smart Contract) and returns the Endorsement responses to theClient. Endorser peer sends the transaction approval or rejection as part of the endorsement response. Client now sends the approved transaction to the o rderer peer for this to be properly ordered and to be included in a block.
Orderer node includes the transaction into a block and forward th is block to the Anchor nodes of di?erent member Organizations of the Hyperledger Fabric network. Fig.: Activity Diagram IV.
Conclusion Thus, blockchain helped us to overcome the problems in the supply chain like eliminating the expired food from consuming. Also, it would help equal distribution of the revenue generated among the participants in the food supply chain. Transparency and secu rity throughout the supply chain is achievable through the project . Also smart contracts can help eliminate costly delays and waste currently due to manual ha ndling of paperwork. V.
