A New Privacy Tech Revolution is Being Ushered in by Zero Knowledge Proofs

From the outside looking in, ZKPs can be viewed as being cryptographic tools that can allow a person to prove the veracity of a given statement to someone else without having to share sensitive information. While on paper, this concept might sound simplistic; its underlying utility can have a deep, profound impact on the realm of privacy tech, affording users a novel means of validating sensitive pieces of information while safeguarding its digital origins and content.

Here’s Why Zero Knowledge Proofs Matter!

In the 80s and ’90s, the idea of ZKPs was confined largely to the realm of science fiction but over the last five years, these tools have been increasingly important within a wide range of industries — primarily as a means of bolstering data privacy, personal security, blockchain scalability, etc.

As a simple example, in their current iteration and capability levels, ZKP-based identity systems can be used for authentication purposes, allowing users to verify the likeness of a person without him/her having to divulge any sensitive data pertaining to them (such as their social security number, or government IDs).

That being said, one area where the promise of ZKPs seems to be the highest is blockchain tech. This is because these novel offerings are capable of meshing numerous off-chain transactions into a single entity, thereby not only allowing for an extremely high degree of data relay efficiency but also amazing security and privacy.

Increasing adoption — The data doesn’t lie.

Straight off the bat, there are numerous reports suggesting that Zero-knowledge proofs (ZKPs) are continuing to witness a significant amount of growth in their global adoption levels since the start of 2023. This rise, in large part, is being driven by a need for data concealment within the blockchain sector. A study by ZKValidator revealed that the use of ZKPs is being spurred primarily by their potential for improved privacy, scaling, and identity management.

Moreover, a large number of mainstream entities have been actively deploying ZKP solutions within their operational frameworks over the past year. For example, Ethereum-compatible L-2 scaling solution Polygon recently revealed that its 2.0 multichain will feature ZK-proofs to assist with asset transfers. Similarly, blockchain software technology company ConsenSys has recently started onboarding partners to its mainnet Linea network, which relies heavily on ZKPs.

Leveraging the power of ZKPs to bolster the future of digital privacy

As more and more crypto projects start to grasp the immense potential held by ZKPs, the market is beginning to evolve rapidly. Enter Horizen, a secure and interoperable blockchain ecosystem that is at the forefront of the ZKP revolution. The project’s sidechain Zendoo helps business entities, developers, and crypto enthusiasts develop public/private blockchains that are capable of offering a high degree of ‘selective confidentiality’ thanks to their utilization of zk-SNARKs, a specialized iteration of ZKPs.

Additionally, Horizen’s tech framework enables quality data integrity and protection against 51% attacks, with the latter being achieved via the project’s use of a novel consensus mechanism. If that wasn’t enough, Horizon has also integrated other security/privacy modules, such as multi-chain block notarization and TLS end-to-end encryption, both of whom are capable of extensive commercial usage in a fully customizable decoupled interoperable blockchain environment.

Lastly, Horizen has also continued to innovate across other domains as well, as highlighted by the launch of the project’s EVM-compatible sidechain and smart contracting platform ‘EON.’ Not only that, the platform has also been working toward the elimination of ‘shielded pools’ from its mainchain. This is being done in order to resolve any lingering privacy concerns in a manner that is sustainable and can foster ecosystem growth in the near-to-mid term.

The path that lies ahead

While ZKPs offer immense benefits, they do come with their fair share of challenges. For example, the simple fact that ZKPs are capable of obfuscating transactions — making them completely anonymous to any third party — may result in them being targeted by regulators as well as other law enforcement entities. To resolve such pain points, developers will have to come up with bypass measures that can ensure that ZKP-centric transactions are compatible with local anti-money laundering (AML) and know-your-customer (KYC) measures.

Despite these challenges, the potential of ZKPs in transforming privacy tech is undeniable. As platforms like Horizen continue to innovate and push the boundaries of what’s possible with ZKPs, we can look forward to a future where privacy and security are not just afterthoughts but integral parts of technology design.
