Introduction:- For many years, the world has been grappling with the challenge of digital identity. The current centralized root of trust model, which relies on CAs, consortia, or governments, has been found to be vulnerable to breaches and hacking attempts. However, with blockchain technology, we can finally solve this global digital identity problem. Blockchain Technology:- A public blockchain is a decentralized root of trust that nobody owns, but everyone can use. It uses a consensus algorithm operating over many different machines and replicated by many different entities in a decentralized network, turning the centralized root of trust model on its head. The Bitcoin network has proven the effectiveness of this model by operating for eight years without a breach. The fundamental idea behind blockchain technology is to replace trust in humans with trust in mathematics. Every transaction in the blockchain is digitally signed by the originator and chained to the prior via a digital ha...

Blockchain technology has the potential to change the face of identity and credential management as we know it. By providing a secure, decentralized, and transparent solution for managing digital identities and credentials, blockchain can offer several benefits over traditional systems. Identity Management:  With blockchain, users can create a  digital identity  that is linked to a public key, offering a unique and tamper-proof identifier that can be used to authenticate their identity when accessing digital services. Additionally, the decentralized nature of blockchain eliminates the risk of a single point of failure that can be exploited by hackers. Credential management:   By storing credentials such as degrees, certifications, and licenses on a blockchain, individuals and organizations can be sure that they are authentic and tamper-proof. When a user needs to share their credentials with a third party, they can do so by providing the public key associated wi...
