How does proof-of-knowledge authentication help create a portable digital identity solution?

Zero-knowledge proofs are probabilistic evaluations that take the effectiveness of portable digital identity solutions to the next level. Web engineers have been working for a long time to figure out if there is a way to prove something to be true without revealing any data to back up the claim. Zero-knowledge proof (ZKP) technology enabled the deployment of cryptographic algorithms to verify the veracity of claims about possession of data without disentangling them. These proof mechanisms have led to advanced mechanisms that improve privacy and security.

Blockchain mining solves problems with centralization, while the lack of privacy in decentralized applications (DApps) can be compensated by ZKP cryptographic algorithms.

This article provides an introduction to zero-knowledge proofs, portable identity, issues with mainstream identity solutions, blockchain-based portable identity solutions, trustless authentication, and the process of building identity. 'password credentials.

A zero-knowledge proof is a cryptographic technique that establishes the authenticity of a specific claim. It allows a protocol to demonstrate to a verifier that a claim about certain confidential information is accurate without disclosing critical information. Technology facilitates interactive as well as non...
