Supply chain management is an important area of logistics. It is a process involving many stakeholders with multiple areas and even more moving parts. The proposed technology aims to make the supply chain more efficient, investing in the wrong technology complicates productivity further while hampering profits, leading to multiple issues in supply chain. Blockchain technology is the solution to the problem of structuring data with built-in security features. Blockchain technology enables decentralization with the participation of members on distributed networks. There is not a single point of failure because of the distributed structure and the transaction record cannot be change by single user. In this paper for making data more secure while sharing information in supply chain a key generation process is done using data sanitization and restoration process and new improved Fittest Self Adaptive sea lion algorithm is discussed using only the authorize person will be able to use shared data and it will be compared with existing model using different parameters.

An information system is very important in today's changing world, and therefore choosing the proper system is becoming a very important decision. With the time, the information systems have become more crucial, with multiple problems affecting the supply chain and the continuous writing of performance areas. The principle of chain management aims at chain values. The working of chain management states that chain management enhances the value of the chain by establishing operational units. Traditional manufacturing supply chains bear a lot from additional, costs, delays and information loss due to information middleware’s. Therefore, we propose a blockchain oriented supply chain architecture to reduce intrusion in traditional ones. Current approaches to private-key security include signature schemes based on bio-metrics, index-hidden private key design, and post-quantum block chain schemes. Nevertheless, recovering the lost private key is difficult in all approaches. Here we proposed an optimal key formation procedure using a fitness-based self-adaptive sea lion algorithm for secure information sharing in SCM using block chain.
