Blockchain (BC) as the widespread innovations in the 21st century has recognized itself to be immutable, tamper-resistant, decentralize and secure.This emerging technology is used as a functional technology for refining present technology and forming new applications for its robustness and disintermediation.Decentralized Digital Self-Sovereign Identity (DDSSI) is an identity mapped with individual identity information along with the user's reputation in the transaction.User's information will be preserved in the decentralized cloud server which will be controlled and maintained by the user.In this research work, we suggest a Blockchain-centered DDSSI wallet to modernizes the existing identity management system that will be used to identify as well as access control to provide validation and endorsement of entities in a digital system.BC technology in this innovation ensures credible and safe information in a transaction besides.Here, we use Bitcoin cryptocurrencies to generate secure and unique DDSSI public key addresses by integrating the private key with the random number for transferring and accepting information and a token-based system to identify customer reputation.
