Wondering about the role of Zero Knowledge Proofs in Blockchain? Let’s start a journey to understand how zero knowledge proofs are changing blockchain.<\/em><\/p>\n

Don\u2019t you think that you are revealing too much personal information about yourself while showing your driving license to the bartender for ID verification? If yes, it is inevitable to look for an innovative way to share only the data that people want to share, rather than disclosing all the information. With the rise of information capitalism, it is important to find solutions that can ensure the privacy and security of user information. <\/span><\/p>\n

While Blockchain<\/a> is a trustworthy alternative for obtaining the desired privacy and security of information exchange, it features transparency as a setback. Therefore, Zero Knowledge Proof (ZKP)<\/a> has been considered as one of the prominent solutions for achieving the requirements of transaction confidentiality. The following discussion points out the essential factors that have been responsible for introducing some striking changes in blockchain.<\/span><\/p>\n

What are Zero Knowledge Proofs?<\/span><\/h2>\n

Cryptography<\/a> has been associated with blockchain as one of the most crucial components since its inception. As a matter of fact, cryptography on blockchain is the foremost reason for its large scale adoption across different industries for various companies. The\u00a0ZKP Blockchain\u00a0applications emerged with the arrival of a new cryptography protocol or mechanism based on mathematical foundations. <\/span><\/p>\n

The introduction of\u00a0zero knowledge proof\u00a0indicated a new chapter in the world of cryptography. It is one of the most prominent examples of cryptographic innovation with diverse applications, including secure and anonymous transactions on public blockchain<\/a> networks and nuclear disarmament.\u00a0<\/span><\/p>\n

Working of Zero Knowledge Proofs<\/span><\/h3>\n

The functionality of ZKP aims at allowing a prover to convince a verifier about a specific fact without revealing the actual information. For example, you can find out the balance in your bank account without having to access your bank details and personal information.\u00a0Zero knowledge proof\u00a0can help in achieving this outcome by leveraging its three fundamental traits. The three fundamental aspects characterizing a ZKP include the following,<\/span><\/p>\n

    \n
  1. Completeness of the transaction is important. It implies that the truth of a statement convinces the verifier about the fact that the prover has possession of the required input.<\/span><\/li>\n
  2. Soundness is the second important trait in the design of a ZKP. It indicates that a dishonest prover cannot convince the verifier about the fact that they have the required input when their statement is false.<\/span><\/li>\n
  3. The final and most critical factor in the design of a\u00a0zero knowledge proof\u00a0refers to zero knowledge. The primary indication of zero knowledge aspect in ZKP points out towards non-disclosure of information. Irrespective of the fact that the statement is true or false, the verifier must not learn anything about the information.\u00a0<\/span><\/li>\n<\/ol>\n

    Types of ZKPs<\/span><\/h3>\n

    Now, let us reflect briefly on the types of ZKPs before moving towards the\u00a0ZKP blockchain\u00a0combination. The two most common types of ZKPs refer to interactive zero-knowledge proof and non-interactive\u00a0zero knowledge proof. Interactive ZKPs involve a series of actions that the prover has to complete for convincing the verifier about a specific fact. <\/span><\/p>\n

    The series of actions in interactive ZKPs are associated with the concepts of mathematical probability. On the other hand, non-interactive ZKPs don\u2019t involve any interactive process. In the case of non-interactive ZKPs, the prover could create all challenges combined together, and the verifier could respond at a later stage. Although non-interactive ZKPs can reduce the possibilities of collusion, they require additional software and machines for identifying the experiment sequence.\u00a0<\/span><\/p>\n

    Another notable category of ZKPs that have emerged recently refer to zk-SNARKs<\/a> or zero knowledge- Succinct Non-Interactive Argument of Knowledge. zk-SNARK is the most popular technique among\u00a0zero knowledge proof\u00a0alternatives. It can help in defining quadratic equation that leverages public data, private data, and inputs for generating proof. <\/span><\/p>\n

    Then, the verifier can validate the proof for completing the transaction. The most renowned example of the use of zk-SNARKs refers to ZCash, a cryptocurrency. In addition, zk-SNARKs can also serve as an ideal choice for tasks such as proving the age of an individual without sharing their personal information.<\/span><\/p>\n
