Blockchain is in its way of revolutionizing different sectors with its decentralized peer-to-peer networking. Smart contracts are the piece of software that have written rules to be executed automatically to update the state of the block chain in a systematic way. One of the main use of Smart contract is in Supply Chain management. Supply Chain management deals with lot of legal contracts at a time. Contracts are agreements between two or more parties that define the duties and obligations for execution of any kind of activities. In this research, we are trying to automate the supply chain related contracts by identifying the important entities such as contract type, start date, end date etc., by using Natural Language Processing methods, then convert the contract to smart contract. This provides an efficient template for creation of smart contracts from natural language contracts and thereby offer best smart contract template for a given type of contract in Supply Chain.

The Internet Of Things

The Internet of Things (IOT) is integrated with supply chain management process to track the product. To track the product smart tags is used. The smart tags like QR code and NFC is used. But with the technology enhancement the block chain is introduced into the supply chain management process. The block chain is the great revolution that data in the centralized form is transformed in to a decentralized manner. The distributed Ledger Technology (DLT) is one of the method used in ethereum block chain. The main advantage of using DLT is, it offers decentralized, privacy-preserving and verifiable process in the smart tags. In existing system only single server was used to maintain all the process like supplier, manufacturer and distributor. In this application we are using different server which was more secure than existing system. The proposed solution in this paper is it checks the product evidence during the entire lifecycle of the product by using the smart contract. The data can be immutable by using smart contract with ethereum block chain. The duplication is manipulated by the block chainserver.

Block Chain

Smart contracts are programs, which are stored in a decentralized network i.e. Block chain. These are written by users to develop decentralized applications using different platform like Ethereum and bitcoin. In current scenario, even though blockchain support features like security and transparency. Because of solidity language vulnerability, there is a possibility of attacks on smart contracts in blockchain. So, to avoid those attacks like i.e. Locked Ether, Transaction order dependency and Time stamp dependency. We discussed, analyzed and tested these attacks in this paper. Further, in our project supply chain management for textile industry using block chain technology, we have developed smart contract using solidity language on Ethereum Platform. With the aim of protecting our project from these attacks, we are thoroughly and experimentally analyzed. And based on the experimental observations, we are going to protect our project from these attacks. All the above mentioned attacks are thoroughly studied and experimentally tested on Ganache, Ropston test network, Rinkeby test network using Remix IDE in JVM, injectedweb3and web3 provider environments. Finally, we have suggested security measures to protect from these attacks

Blockchain technology, as a distributed digital ledger technology that ensures traceability, security, and transparency is displaying potential for easing some comprehensive supply chain problems. Scholars have started analyzing systematically the potential benefits and effects of block-chain on numerous activities of an organization. This paper presents the barricades in the adoption of blockchain technology in supply chain management. The potential benefits of blockchain adoption such as quality, cost, speed, transparency, durability, and immutability are also discussed in this paper. We present the early literature discussing the use of blockchain in the field of the supply chain to enhance accountability and transparency. This study explains the several mechanisms by which supply chain managers can prepare their organizational structure to adopt the latest technology. It further highlights the mechanisms to achieve supply chain objectives. Part of this paper also discusses how blockchains, a potentially disruptive solution that is on its early evolution, can overcome several potential barricades. Future research directions are proposed which can further provide insights into overcoming barriers and adoption of blockchain technology in the field of supply chain management.

Proposed Model

Blockchain is a trusted distributed ledger shared across the business processes. Blockchain technology focuses on automating tasks in a distributed environment. Proving as one of the effective platforms, it helps in mapping the physical commodities to the digital ledger. A digital ledger is like an electronic register for storing the transactions that are taking place among various commodities. The physical commodities include suppliers, manufacturers, exporters, consumers and distributors wherein the distributor plays a major role in determining the product standards. To this end, this paper presents a Blockchain design for securing Supply Chain Management (SCM) in Coffee Retailer Network (CRN). The proposed design made with the view that it further be implemented with smart contracts to establish a private or consortium Blockchain application for the asset tracking processes in the coffee retailer network. The proposed model can bring transparency, sustainability and efficiency in asset tracking.

This paper provides a detailed overview of the block chain technology and how it can be used to build a foolproof system in eliminating counterfeit products in pharmaceutical industries. From the last decade, pharmaceutical companies are facing difficulties in tracking their products during the supply chain process, allowing the counterfeiters to add their fake medicines into the market. Counterfeit drugs are analysed as a very big challenge for the pharmaceutical industry worldwide. As indicated by the statistics, yearly business loss of around $200 billion is reported by US pharmaceutical companies due to these counterfeit drugs. These drugs may not help the patients to recover the disease but have many other dangerous side effects. According to the World Health Organization (WHO) survey report, in under-developed countries every 10th drug use by the consumers is counterfeit and has low quality. Hence, a system that can trace and track drug delivery at every phase is needed to solve the counterfeiting problem. The block chain has the full potential to handle and track the supply chain process very efficiently. In this paper, we have proposed and implemented a block chain based drug supply chain management. Our proposed system block chain-based drug supply chain management for consumers. In this drug supply chain management the system is deployed using Hyper ledger fabrics which is capable of continuously monitor and track the drug delivery process in the smart pharmaceutical industry. Finally, we also perform several tests to check the efficiency and usability of our proposed system.

Blockchain has become a powerful technology and when it comes to supply chain management, blockchain has a lot to offer which could contribute to its development and make the supply chain more effective. The same benefit could be also gained when blockchain is incorporated in the Military Supply Chain Management (MSCM). Theaim of this paper is to develop and integrate blockchain in the MSCM. The developed MSCM is focusing on three (3) main blockchain components, which are transparency, integrity and secure communication. The methodology to develop the MSCM blockchain similar to UnicalCoin. The findings show that incorporating blockchain into the MSCM enables transparency, integrity and secure communication. Thus, blockchain may reduce fraud, improve communication between parties and made end-to-end tracking transparency in MSCM. Future work is to embed a smart contract feature to automate some processes in MSCM.
