There are few crypto abbreviations that carry more weight than the letters ZKP. Zero-knowledge proofs are a powerful technology with a wide range of use cases, from financial privacy to identity verification. As understanding of this blockchain-adjacent technology has grown, so has the number of proposed applications for ZKPs. But despite the enormous potential, adoption of zero-knowledge-based protocols has so far been limited to a handful of Layer 2 networks.
The reason for the lagging adoption concerns some of the challenges associated with ZKPs, including the increased computational burden on blockchain networks. But Web3 developers don’t give up easily, and a number of zero-knowledge projects have created solutions that will enable ZKPs to achieve the industry-wide adoption they deserve.
What you need to know about zero knowledge
Don’t let the name fool you: there’s a lot to learn about zero-knowledge technology, which adds an extra layer of complexity to blockchain design. For engineers who are au fait however, for ZKPs the trade-off is worth it because of the use cases that zero-knowledge technology supports, especially in the context of privacy.
ZKPs allow one party to prove to another that a statement is true, without revealing the underlying information used to prove it. It sounds like a niche technology with marginal applications, but in fact this capability has huge implications for building decentralized applications. Not only can sensitive financial data be hidden on public networks, but also personal data, allowing for example KYC/AML at the protocol level to access RWAs, without creating a wealth of data for hackers to target.
As promising as ZK technology is, there are a number of challenges that developers face. In short, because they are compute-intensive, ZKPs make scaling difficult, and the complexity of the technology can hinder broader adoption from both developer and user perspectives. Additionally, the need for a random number generator to create a trusted setup when creating a ZK protocol poses a theoretical attack vector that requires robust access controls to prevent compromise.
Making ZKPs a real game-changer
Zero-knowledge technology has the potential to be a real game changer in privacy, healthcare, commerce, real-world assets and much more. But for this to happen, the benefits of implementing it must outweigh the drawbacks, such as an increased development burden. Fortunately, recent innovations in ZK technology make it easier to work with and overcome some of its well-documented disadvantages.
From a security perspective, a recent research paper has shown that zero-knowledge proofs can be developed to prevent information leakage – even when the RNG involved in proof generation is reused. This is a major breakthrough that will give companies greater confidence in the sanctity of ZKPs and lead to greater adoption in information-critical areas.
From a blockchain developer’s perspective, improvements in modular design have allowed builders to support ZK-based solutions without adding complexity to their existing tech stack. Modular design is a cornerstone of blockchain architecture, but ZKPs have proven more difficult to pioneer. Thanks to protocols like Pera (formerly dWallet), web3 projects can now enjoy the benefits of zero-knowledge technology without the drawbacks.
Pera’s ZK implementation focuses on preserving user privacy through the use of Zero Trust Protocols (ZTPs) that can operate across multiple chains without requiring third-party dependencies. As a result, it is much easier to implement cryptographic authentication for, for example, user identities on any network.
The best is yet to come
The technology is now in place for ZKPs to fulfill the kinds of use cases the technology has long been envisioned for, starting with on-chain privacy and data processing. The security, accessibility and scalability challenges have all been resolved, leaving adoption as the biggest hurdle. In other words, the technology is there, but it needs to be widely adopted, and not just on ZK L2s, but across the entire multichain landscape. If that can be achieved, zero-knowledge technology will no longer be talked about in terms of what it can ultimately achieve, but in terms of how it solves real problems in the here and now.
