, Zero-knowledge proofs are used to establish the truth of a claim without disclosing the claim itself. The “prover” is the person making an assertion, while the “verifier” is the party checking that assertion. In a 1985 work by Shafi et al, titled “,” the term “zero-knowledge proof” was first used along with the following definition.
However, this method has certain drawbacks, the most significant being a loss of privacy. Shared personally identifiable information isin centralised databases that hackers may easily access. There have been requests for more private ways to share information in light of the growing problem of identity theft.
This issue is addressed by zero-knowledge proofs, which do not need secret information to establish the veracity of a claim. The statement is sent through the zero-knowledge protocol, which then outputs a brief justification for the statement’s veracity. The information needed to create the evidence is kept secret while providing strong assurances that the assertion being proven is accurate.
Referring to our original illustration, a zero-knowledge proof is required to back up a claim of citizenship. The verifier may be persuaded that the underlying assertion is true by only confirming that specific aspects of the evidence are actual.
