Best Zero Knowledge (ZK) Proof Projects For 2025

Polygon is an easy-to-use platform where Ethereum scaling and infrastructure development could take place. Over the year, Polygon has turned out to be a ZK proof powerhouse. Zero Knowledge proof projects are considered the end game when it comes to scaling, however, the possibility is holding high speculations.

The ZK technique from Polygon encourages strong teamwork and information sharing that would not be possible otherwise, while allowing independent teams to experiment with other strategies. When taken as a whole, the ZK investments represent a diverse wager on the development of this technology.

Immutable X uses an application-specific zk proof project with StarkEx, an NFT platform that makes it easier to produce and trade NFTs and tokens. Even when the Ethereum network was congested, the platform supported tens of millions of NFT mints and trades all with little fees.

StarkNet will also host the debut of Immutable X. Immutable X will submit its proofs on StarkNet rather than directly to Ethereum, and StarkNet’s rollup will then recursively post those proofs to Ethereum. After that, Immutable X can use StarkEx to introduce app chains on top of StarkNet, effectively giving projects a layer-3 scaling option.

One of the first digital assets, Zcash—previously known as ZeroCash—helped establish the usage of zero-knowledge technology in the sector by supporting its privacy-preserving transactions with a zero-knowledge proof. One cryptocurrency that focuses on privacy is Zcash, which uses zk-SNARKs, a zero-knowledge proof mechanism.

Zero-knowledge proofs are currently being used to ensure the confidentiality of financial transactions. Zero-knowledge proofs, however, might be more important in maintaining online activity privacy. With the introduction of data mining and systems that monitor users’ online behavior, privacy in online interactions is no longer guaranteed, making zero-knowledge proofs and other similar solutions more and more relevant.

The Ouroboros Samasika consensus algorithm, which employs a modified PoS model, is used by the Mina blockchain. Mina uses the SNARK technique to validate the transactions in order to grow the ecosystem. This SNARK, however, is distinct from the others mentioned. The system continues to be genuinely decentralized, scalable, and encouraging for anyone to join and leave.  Through the usage of ZK Proofs, Mina has envisioned a new economic structure that preserves anonymity, financial incentives, and even expands the ecosystem.

A low-cost decentralized crypto trading platform was developed by dYdX in collaboration with StarkWare’s StarkEx L2 solution to provide qualified traders with greater security and speed. StarkEx employs ZK rollup technology to speed up transactions and dramatically lower gas costs on the Ethereum network.

Loopring has significantly contributed to the simplification of cryptocurrency trading. It offers traders with a fully non-custodial and utterly anonymous setup.  The project introduces hybrid form of ZK Proof is being introduced by Loopring in its operational mode in order to expand DEX, or Decentralized Exchanges.

Order-messaging will be handled off-chain in the Hybrid ZKP model provided by Loopring, whereas settlement will occur on-chain in real-time with no delays.

Through the DEX, Loopring seeks to completely change trading by implementing an order mechanism that is quick, effective, affordable, and wholly non-custodial. Additionally, Loopring introduces isolated exchange contracts, which will totally conceal transactions and provide enough privacy.

World ID is designed to allow for anonymous use. In addition, third parties are unable to correlate various activities conducted with a person’s World ID through the World ID data. World ID actions are not linked to a person’s iris images or iris code. This is how it is possible.

A ZKP is utilized when a person uses their World ID to stop outsiders from learning their public key for their World ID or following them across applications. ZKPs further prevent the use of World ID from being associated with any biometric information or the individual’s iris code.

Metis, is a ZK proof project that has been created to support optimistic roll-ups taking centre stage when scaling the ETH base layer. The validators/rangers are provided with particular blocks as samples under the Metis Ranger system. Before the mainchain validators can contest the transaction, these rangers must first inspect it and submit proofs of its legitimacy. In order to scale up the use of optimistic roll-ups in scaling needs, this approach allowed validation and withdrawal times that required weeks on the layer 1’s or mainchain to be performed in hours and minutes.

Horizen is rolling out zero-knowledge proof projects for many blockchain systems. Platforms can take inputs and outputs using this technique without disclosing private client information. For exchanges and other big platforms who want to dispel any potential suspicions about how they function, this kind of auditing can be vital, especially when combined with off-chain reserve and liability auditing.

Crypto exchanges can produce cryptographic verification of both their asset reserves and outstanding liabilities using zero-knowledge proofs. Similarly, cryptocurrency lenders might provide evidence that money was lent to respectable counterparties. In either scenario, the entities would never be required to disclose their counterparties’ names or the amount of reserves they have to the public.

Telos Private will make it possible to conduct transactions using “zero-knowledge proofs” (ZK). To support ZK transactions and bridges to and from Telos, it will use a distinct side-chain with updated code. Decentralized Telos block producers who were chosen through user voting will run the side-chain.

The possibilities of zero-knowledge proofs are almost limitless. Privacy is one of the essential elements that is missing from this new adoption phase. Specifically, how can highly regulated institutions tokenize assets that could include private or sensitive information on a public blockchain.

This makes it possible for businesses to make money out of tangible assets like accounts receivables, trademarks, intellectual property, and even machinery while guarding against unneeded disclosures of information.

Here are some instances of how ZK Proofs can be used in the digital and traditional economies to address issues and create new possibilities.

• Healthcare

ZKPs can be used so that a patient can demonstrate evidence of accurate computation, enabling the verifier to affirm that they are qualified to get a specific therapy or prescription without disclosing their unique medical history in response to a challenge made to the prover.

ZK Proof projects can also make it possible for pharmaceutical products to have undergone a full audit without disclosing sensitive information that could include patient or intellectual property.

• Financial Services and Defi

ZKPs can help users provide proof that they are qualified to use certain financial products or should be granted a loan without revealing their age or net worth.

• Real-World Resources

The acceptance of cryptocurrencies by the general public will soon move toward real-world assets. In the last three years, Defi protocols like Aave and Uniswap have set the stage for people and organizations to trade and lend their digital assets using safe, trustless, and highly effective smart contracts.
