Chainlink and Zero-Knowledge Proofs: Transforming Privacy

• Zero-knowledge proof technology is gaining traction on privacy-focused subjects.
• Chainlink is among the protocols developing this unique technology.

As much as crypto enthusiasts are excited about technological advancements and innovation, they are still very anxious about keeping their data and other personal details private. 

These individuals would rather avoid the exploitation of their personal data by governments, corporations, social media platforms, and banks. Hence, the embrace of emerging cryptographic technology is known as zero-knowledge proof. 

“Blockchain tech and ZK-proofs could be used as built-in safeguards … to verify the origin, authenticity, & ownership of AI-generated files,” explains @ChainlinkLabs‘ @Dahlia_Malkhi in this @CointelegraphZN post.

With many outfits like Chainlink developing this tech, it is globally believed that zk proofs can offer both privacy and trust, two factors that are lacking all around the world. According to Polygon co-founder Jordi Baylina, there are several applications for the zk technology including anonymous voting and decentralized games. 

The cryptocurrency and blockchain technology industry is one of the first sectors that opened its doors to the adoption of zero-knowledge proofs. Currently, the cryptographic technology is utilized for scaling Ethereum (ETH) transactions while making sure that they are cheaper and faster. Earlier this year, Polygon (MATIC) began to explore the integration of zk technology into its Proof-of-Stake (PoS) main chain.

The development was proposed by Mihailo Bjelic, the co-founder of Polygon (MATIC) who believes that the network will receive more advantages while remaining compatible with the Ethereum Virtual Machine (EVM). It would also eliminate reorganizations, and in the long run, pave the way for expedited transaction confirmations for network users.

Multiple Use Cases of Zero-knowledge Proofs 

Markedly, it is believed that beyond this utilization of zero-knowledge proofs within the crypto and blockchain sector. Zero-knowledge can easily prove personal information without having to fully disclose the user’s personal information. It is an efficient tool for fighting against the spread of fake news as it can be used to verify the source of the news.

For example, zk-Proofs could help convince banks that a person’s income is above a certain threshold (to qualify for a mortgage) without actually revealing the individual’s actual income. Also, it could be used to convince the agency in charge of elections that you are a resident or citizen without giving them any form of identity card like driver’s license or passport. In addition, it could be leveraged in the case of electronic voting which the world has been slow to catch up with.

Central Bank Digital Currencies (CBDCs) have been limited by a number of questions surrounding privacy. It is possible that zero-knowledge proof is part of the solution to tackle this problem. 

Noteworthy, zk proofs were first introduced in the 1980s but in recent times, it is fast gaining traction with many people embracing it because of its capacity to fish out false information. There is a current struggle against this misleading information in the wake of AI-altered documents, images and identities. 

In May, Ethereum-based decentralized blockchain network Chainlink adopted the fast-growing cryptographic technology to revolutionize Web3.0. To emphasize the functionalities of the zero-knowledge proof, Chainlink illustrated using a Bob and Alice analogy which demonstrates that transactional partners can now assure themselves of the security of their deal without discussing additional information that may jeopardize their wallets.
