International Journal of Blockchains and Cryptocurrencies (IJBC), Vol. 2, No. 2, 2021

Abstract: Since the development of blockchain technology, many industries are re-engineering business processes. Like all other industries, the supply chain is also trying to adopt blockchain as it reduces the time and cost factor in delivering the products from point of production to point of consumption. The bigger the size of a blockchain, the more time it takes to validate the chain. Reducing blockchain validation time is an open question and many researchers are doing research to address this problem. In this article, we proposed a DAG-based blockchain architecture suitable for supply chain and IoT devices. In the proposed architecture, we made structural changes in the linear blockchain to transform it into a DAG-based blockchain. The proposed DAG-based blockchain takes O(log(n)) time as compared to O(n) in the traditional linear blockchain.
