ShardLab Launches ZK-Based Tool for Digital Identity and NFT Vouchers

Blockchain developer ShardLab has introduced a groundbreaking web application designed to streamline voucher distribution using NFTs.

ShardLab, the blockchain division of the web3 venture capital firm Hashed, has unveiled an innovative web application that leverages account abstraction (AA) and zero-knowledge proofs (ZK) technology. This new tool aims to simplify the use of decentralized identity and voucher distribution.

Key Features of ShardLab’s New Tool

  • Zero-Knowledge Proofs: The application uses zk technology to verify user identities without sharing private information, enhancing privacy and security.
  • NFT Vouchers: Users can receive and redeem vouchers as non-fungible tokens (NFTs) via QR codes, streamlining the redemption process.
  • Real-World Implementation: The tool was successfully demonstrated at the Southeast Asia Blockchain Week 2024. Attendees integrated NFT vouchers with point-of-sale (POS) systems at over 60 restaurants and shops at ICONSIAM, a themed shopping mall in Bangkok. This showcased the practical and efficient use of blockchain technology in a real-world retail environment.

Practical Benefits

ShardLab emphasized that the combination of account abstraction and NFTs allowed ICONSIAM’s attendees to redeem their vouchers seamlessly. By scanning a QR code, the voucher amount was automatically deducted from the bill, avoiding traditional smart contract complexities.

“By integrating cutting-edge technologies like zero-knowledge proofs and account abstraction, we are paving the way for a future where blockchain is not only secure but also straightforward and convenient for everyday users,” said Hojin Kim, CEO of ShardLab.

Conclusion

ShardLab's latest innovation demonstrates the practical applications of blockchain technology in everyday retail settings, enhancing both security and user experience. This launch marks a significant step forward in the integration of blockchain solutions in real-world scenarios, paving the way for broader adoption and convenience.
