In the digital era, where data has become one of the most valuable assets, information security is a top priority for every business. This is especially true in sectors like finance, supply chains, and manufacturing—such as the seafood industry—where sensitive data about customers, transactions, and production processes are attractive targets for cybercriminals. In this context, Zero-Knowledge Proof (ZKP) emerges as an advanced security technology that is reshaping many industries.
So what exactly is ZKP Why is this solution gaining such prominence? How is it being applied both globally and in Vietnam, even among small and medium-sized enterprisesSMEor companies operating in the seafood sector? Let’s dive into the details below.
What is Zero-Knowledge Proof (ZKP)? – The Trust Foundation of the Digital Economy
Zero-Knowledge Proof (ZKP) is a mathematical method that allows one party (the prover) to confirm to another party (the verifier) that they know a specific piece of information without revealing what that information is. A simple example: proving that you're of legal age to enter a bar without disclosing your exact birth date—just a confirmation like “Yes – I am over 18.”

- Smart contractSelf-executing code stored on the blockchain that automatically enforces contract terms without intermediaries.
- Web3: The next-generation decentralized web, integrating digital assets, NFTs, and privacy-focused systems like ZKP.
- IoT (Internet of Things): A network of connected sensors and devices that exchange data via the internet.
ZKP enables verification of access rights, transaction authentication, or validation of data without exposing the underlying data. This breakthrough is vital when businesses must protect trade secrets while maintaining transparency in their processes.
ZKP in Finance – A New Era of Transparent and Secure Transactions
In finance and banking—where massive volumes of transactions take place every second between individuals, organizations, and businesses—ZKP offers several powerful applications:
1. Private and Secure Payments
A prominent example is Zcash, a cryptocurrency using ZKP to ensure that all transactions remain confidential, hiding the identities of both parties. This meets the security needs of individuals and enterprises making large-scale or cross-border payments while still complying with anti-money laundering laws.
2. Identity Verification Without Disclosing Personal Data
Current Know Your Customer (KYC) procedures are complex, time-consuming, and susceptible to personal data leaks. ZKP allows customers to prove their eligibility (e.g., Vietnamese nationality, over 18, valid work permit…) without submitting all personal data to every bank or partner. This helps SMEs protect customer data while streamlining online registration.
3. Efficient Smart Contracts on the Blockchain

ZKP Reshaping Supply Chains – Transparent, Traceable, and Fully Secure
Beyond finance, ZKP is quickly spreading to supply chains, especially in agriculture, forestry, and aquaculture:
1. Traceability Without Revealing Trade Secrets
Products like exported seafood (e.g., pangasius, tuna) from Vietnam often require proof of origin, farming methods, and absence of banned substances. Integrating ZKP with blockchain or IoT systems allows verification of data from seed stock, feeding, harvesting, storage, to logistics. Crucially, only necessary data (e.g., harvest date, farming zone ID) is disclosed to international buyers, while production secrets such as feed formulas remain strictly confidential.
2. Fraud Prevention and Brand Protection
Traceability fraud, such as altering farming zone codes, can cause significant losses to businesses and the national economy. With ZKP applied to electronic documents and certifications, SMEs can establish low-cost, automated verification systems that ensure transparency without relying on third-party services.
Case Study: Walmart and IBM Food Trust
Walmart uses blockchain integrated with ZKP to trace food products from farms to supermarket shelves. A potentially contaminated batch can be traced in just 2.2 seconds (versus weeks of document checks). Vietnamese logistics and seafood export firms have taken interest in exploring this solution.
SMEs and Vietnam’s Seafood Sector: Seizing Opportunities from ZKP
Although complex, ZKP is accessible to SMEs in the seafood sector thanks to “as-a-service”software offerings. You don’t need to build solutions from scratch—simply leverage platforms from startups or tech giants (like Microsoft, IBM, or Vietnamese tech firms).
Quick Guide to Getting Started:
- Define a specific challenge: e.g., verifying product origin without exposing detailed farming data.
- Select a ZKP solution/platform provider (Blockchain Service Provider).
- Consult tech experts and risk managers to integrate ZKP into your supply chain tracking or transaction management systems.
Are you a small business exporting shrimp to the EU? A blockchain-based traceability solution with ZKP integration can help you prove compliance with standards without revealing proprietary production details to foreign customers—a crucial advantage in today’s competitive global market.
Conclusion: ZKP – The Next Breakthrough in Digital Transformation and Data Security
Zero-Knowledge Proof (ZKP) s more than a buzzword; it’s becoming the gold standard in security as Vietnamese enterprises—especially SMEs—accelerate digital transformation. Regardless of industry or size—from banking to logistics to seafood—early adopters of ZKP gain strategic advantages in protecting trade secrets, building trust, and driving innovation.
