Wondering about the role of Zero Knowledge Proofs in Blockchain? Let’s start a journey to understand how zero knowledge proofs are changing blockchain.

Don’t 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.

While Blockchain 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) 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.

What are Zero Knowledge Proofs?

Cryptography 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 ZKP Blockchain applications emerged with the arrival of a new cryptography protocol or mechanism based on mathematical foundations.

The introduction of zero knowledge proof indicated 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 networks and nuclear disarmament. 

Working of Zero Knowledge Proofs

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. Zero knowledge proof can help in achieving this outcome by leveraging its three fundamental traits. The three fundamental aspects characterizing a ZKP include the following,

  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.
  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.
  3. The final and most critical factor in the design of a zero knowledge proof refers 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.

Types of ZKPs

Now, let us reflect briefly on the types of ZKPs before moving towards the ZKP blockchain combination. The two most common types of ZKPs refer to interactive zero-knowledge proof and non-interactive zero knowledge proof. Interactive ZKPs involve a series of actions that the prover has to complete for convincing the verifier about a specific fact.

The series of actions in interactive ZKPs are associated with the concepts of mathematical probability. On the other hand, non-interactive ZKPs don’t 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. 

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

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.

How Can You Use ZKPs in Blockchain?

As of now, you must have anticipated the different reasons that point out towards using ZKPs in blockchain. Although the ZKP blockchain symbiotic relationship has not been discussed enough, industry leaders, professionals, and decision-makers are recognizing the value of ZKPs.

The scalability of ZKPs can allow the growth of blockchain while also providing the assurance of flexibility to users, along with improved control and freedom related to their information. Therefore, it is inevitable to wonder about the potential ways in which ZKPs are actually changing the world of blockchain.

In order to find how zero knowledge proof is changing blockchain, let us reflect on the different areas in the blockchain system where ZKPs are applicable. 

  • Messaging Applications in Blockchain 

The foremost area of application for ZKPs in blockchain refers to messaging. End-to-encryption is a mandatory requirement in a privacy-oriented world. Encryption of messages aims at ensuring that no third party is able to view the communication between two individuals.

Generally, messaging platforms require that users should verify their identity to the server, and the server must recognize the user. On the other hand, zero knowledge proof allows the development of end-to-end trust in the world of messaging without leaving out any additional information. Therefore, the applications of ZKP in messaging applications are one of their major applications in the domain of blockchain. 

  • Authentication Processes

The transmission of sensitive information has slowly turned into a massive priority for enterprises, especially with radically expanding information systems and relevant functionalities. Zero knowledge proof can provide the ideal platform for transmission of sensitive information such as authentication information along with the assurance of improved security.

Zero knowledge proofs can help in development of a secure channel tailored for users to use their information without exposure. As a result, ZKPs can help considerably in avoiding the concerns of data leakage in the worst-case scenarios.

Most important of all, the access channels also enjoy formidable safeguards that enable a highly secure and seamless experience. 

  • Safeguards for Sensitive Information

The role of zero knowledge proof in changing blockchain is also important for defining the approaches followed by blockchain for revamping transactions. ZKP can offer a high-end security level for all blocks that contain vulnerable banking information such as financial information and transaction history.

The high-end security level allows banks to introduce modifications only in the required blocks upon any user’s request for information. At the same time, the other blocks are not tampered with, thereby providing the assurance of comprehensive protection. 

  • Transmitting Private Blockchain Transactions 

Transmission of private blockchain transactions is one of the prominent mentions among different notable implementations of ZKP in blockchain. Private Blockchain transactions must be safeguarded from any third party while sending them.

The most important concern in sending private blockchain transactions refers to the various loopholes evident in the conventional methods. The effective integration of zero knowledge proof with private blockchain transactions can make them resilient towards any form of hacking or interception.
