<p class="is-style-lead">Blockchain developer ShardLab has rolled out a new web application aimed at simplifying voucher distribution in the form of NFTs.</p> 
<p>ShardLab, a blockchain arm of web3 venture capital firm <a href="https://crypto.news/tag/hashed/" target="_blank" rel="noreferrer noopener">Hashed</a>, has unveiled a web application leveraging account abstraction (AA) and zero-knowledge proofs (ZK) technology to simplify the use of decentralized identity and voucher distribution.</p> 
<p>Leveraging zk technology, the application can confirm user identity without sharing private information. It also allows users to receive and redeem vouchers in the form of non-fungible tokens (<a href="https://crypto.news/tag/nft/" target="_blank" rel="noreferrer noopener">NFTs</a>) via QR codes, ShardLab explained.</p>

<p>The firm says the launch was the result of a successful release at the Southeast Asia Blockchain Week 2024, where attendees could integrate NFT vouchers with the point-of-sale (POS) systems at over 60 restaurants and shops at ICONSIAM, a themed shopping mall in Bangkok.</p>

<p>“This implementation demonstrated the practicality and efficiency of blockchain technology in a real-world retail environment,” ShardLab says.</p> 
<p>The firm noted that thanks to account abstraction and NFTs, ICONSIAM’s attendees could natively redeem their vouchers by scanning a QR code, automatically deducting the voucher amount from the bill, without facing traditional hurdles tied to smart contract usage.</p> 
<p>“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.</p>
