Implementation and Testing of a Blockchain based Recruitment Management System

Blockchain Technology is used to develop applications more easily and maintain the information as safe and secure. This work is aimed towards developing a recruitment process supported by blockchain technology. Currently, a manual system is used to recruit employees; Manual recruitment is a time consuming, costlier non-secure process. Selection and recruiting the candidates is a vital process for an organization. The proposed method uses blockchain technology for the recruitment process. The entered candidate details are verified by the college, organization for the last workplaces, and law enforcement. Based on the approval, the candidate data is stored in a block with its transaction hash value. The transaction hash consists of the unique predefined fixed-length text of the block and it secures the data from tampering. SHA-256 is one of the hashing algorithms to develop a transaction hash. Once the candidate information is stored in the blockchain, the recruiters read the candidate data from the blockchain and select the validated candidate for the recruitment process. It ensures that they are retrieving the valid details of candidates and can proceed for the further recruitment process. The technology uses a Smart contract under the Ethereum platform to provide security for the recruitment application and tested using the Ganache tool.
