Zero-knowledge technology has the potential to play a more integrated role in on-chain activities.
In this blog, we explore the perks and functionalities of implementing ZK technology development into your blockchain projects and why it stands out as an epic in the industry.
Rollups are currently a leading scalable solution, bundling hundreds of transactions into a single Ethereum chain transaction, significantly reducing gas fees. While executed off-chain, transaction data is posted to the Ethereum network. Two types of rollups include Optimistic Rollups and ZK-Rollups.
Optimistic Rollups assume transactions are valid but can be challenged if necessary, subject to a delay for fraud-proof challenges. ZK-Rollups use validity proofs, where off-chain computed trades are supplied to the Ethereum mainnet as compressed data, known as ZK-Proofs. ZK-Rollups represent hybrid scaling solutions, deriving security from Ethereum, making them notably safer than pure off-chain scaling solutions.
What are Zero-Knowledge Proofs?
Zero-Knowledge Proofs (ZKPs) use cryptographic techniques to verify data without disclosing the actual data itself. This concept revolutionizes the landscape of data collection and maintenance.
ZKPs enable the solution of problems without revealing the underlying data to the verifier, ensuring utmost confidentiality. This confidentiality is pivotal in safeguarding sensitive information such as passwords, preserving the integrity of the entire ecosystem. In a ZKP framework, the zero-knowledge property attests to completeness, soundness, and the absence of information disclosure to the verifier.
What are the Different Types of ZK-proof-based Protocols?
In essence, ZK technology encompasses a suite of protocols based on Zero-Knowledge (ZK) proofs, including:
- STARK – Succinct Non-Interactive ARguments of Knowledge
- SNARK – Scalable Transparent ARgument of Knowledge
- VPD – Verifiable Polynomial Delegation
- SNARG – Succinct Non-interactive ARGuments
Two Prominent Types of ZK Technology
Beyond the confines of blockchain, Zero-Knowledge (ZK) technology finds applications in realms like authentication and nuclear disarmament. Within the blockchain landscape, zero-knowledge proofs have evolved significantly in recent years, manifesting in two prominent types of ZK technology, including:
ZK-SNARK stands for Zero-Knowledge Succinct Non-Interactive Argument of Knowledge, each letter encapsulating a defining characteristic:
Zero-Knowledge (ZK): The protocol allows verification of a fact without revealing the fact itself.
Succinct: The proof is more compact and more accessible to verify compared to the underlying fact.
Non-interactive: Prover and verifier interact only once due to a shared key.
Argument of Knowledge: The protocol must meet stringent “soundness” criteria to prevent cheating, making it challenging for those without knowledge to generate a ZK-SNARK.
Initially developed by Zcash for private cryptocurrency transactions, ZK-SNARKs rely on a trusted setup for creating the shared encryption key, introducing a level of reliance that falls short of complete trustlessness for everyday transactions.
ZK-STARK, denoting Zero-Knowledge Scalable Transparent Knowledge of Argument, introduces distinct features from ZK-SNARKs:
Scalability: ZK-STARKs generate and verify proofs swiftly, particularly when handling substantial amounts of data. They exhibit efficiency even with exponentially larger datasets, with only a marginal increase in verification time.
Transparency: ZK-STARKs leverage publicly verifiable randomness to create the necessary shared key for zero-knowledge proof, eliminating the need for a trusted setup.
While ZK-STARKs offer advantages in scalability and transparency over ZK-SNARKs, their generation of more intricate proofs generally leads to higher transaction costs.
Ensuring User Privacy: The Role of ZK Technology in Blockchain Security
Public blockchains disclose comprehensive transaction details, revealing wallet addresses and transferred or available balances. In contrast, Zero Knowledge Proofs (ZKPs) eliminate unwanted information that doesn’t serve the intended purpose.
In scenarios where the objective is to confirm the transfer of an amount from wallet A to wallet B, ZKPs provide a solution by revealing only the balance state of wallet A or wallet B. They crucially safeguard the public key of the wallet from exposure.
Historically, law enforcement agencies have exploited vulnerabilities in public key cryptography to trace crucial information for criminal investigations. While this practice serves a legitimate purpose, it also introduces the risk of deanonymizing prominent wallets with substantial balances.
The vulnerabilities associated with public blockchains, such as dusting attacks, threaten user privacy. ZKPs offer an immediate remedy by mitigating these issues, enabling individuals to conduct operations atop the blockchain with complete confidentiality.
The Inner Potential Capabilities of ZK Tech Development
Zero-Knowledge (ZK) technology is recognized for its immense potential, offering solutions in privacy, security, scalability, interoperability, and sovereign identity, according to a report from FS Insight. The technology’s application in privacy and authentication has already demonstrated product-market fit, with expectations of further expansion in implementation. ZK proofs enable secure information verification without divulging details and present a promising avenue for efficiently scaling Ethereum. Notable protocols like Polygon, Aztec, and ZK-Sync have successfully incorporated zero-knowledge technology, particularly in the form of Zero-Knowledge rollups for Ethereum layer two protocols.
Considering the ZK technology’s capacity to anonymize blockchain transactions increases regulators’ likelihood of applying anti-money laundering (AML) and know-your-customer (KYC) measures to ensure the legality of transactions involving ZK technology.

The Contribution of ZK Technology in DeFi
Zero-Knowledge proofs (ZKPs) are ideal for various financial applications because they provide a private and safe way to verify data without revealing transaction details. This covers spaces like dark pools, advanced financial instruments that allow users to trade anonymously without disclosing their identity or personal information, and online economies.
Despite their recent boom in popularity, decentralized financial protocols, or DeFi, face various obstacles, including adoption restrictions from institutions and enterprises.
