Storing & Accessing Private Data on the Blockchain with an NFT — #builditonXDC

Non-fungible tokens (NFTs) have soared in popularity over the past year or so, and now have a solid footing in our consciousness. That being said, the public perception of NFTs and their usefulness is largely limited to trendy artwork and internet buzzwords. While use cases for NFTs are almost limitless as a blockchain-based accounting mechanism, crypto enthusiasts and developers have only scratched the surface of their capabilities.

You may even hear about using NFTs for art, gaming, fashion, social media, and music — or perhaps the digitization of real-world assets. But a lot of the most practical uses are understated, especially as trade accounting tools, as methods of ownership, and even for ownership and access to data.

The XDC Network made headlines when it was used to complete the first trade-finance based transaction with an NFT, but there are a host of other NFT use cases with XDC’s Network able to store private information in smart contracts to access it later.

It would be relatively easy to create a dApp allowing multiple parties to pass data from one contract to another while keeping access totally restricted to those who are authorized by the token on the XDC Network.

This data could be KYC data, ticket info, medical data, identity information, login information, or anything else extremely sensitive and worthy of protection.

In this example, we’ll store a Social Security Number in a contract that will mint an NFT on the XDC network while placing the SSN data into the contract & only allowing the data to be seen by the holder of the token. Fundamentally, the concept of minting a token is no different than minting any other NFT. The contract code governs the use of the token, and this contract gives the holder of the token a security tool to manage data.

This is only possible on blockchains with privacy capabilities. Most blockchains are public, while the XDC hybrid Network has both Public/Private ledgers, allowing the safe access of private data. Users of these future dApps will not have to worry about their information falling into the wrong hands with a DB breach or being broadcasted to the entire world publicly. With XDC’s low gas fees, fast performance, and privacy, the XDC Network can create an ecosystem of reliable trade finance and security tools on the blockchain.

XDC Weekly August 11th - August 17th, 2024

SUNNYVALE, Calif., Aug. 15, 2024 /PRNewswire/ -- Plug and Play has announced a new accelerator focused on real-world asset (RWA) tokenization on the XDC Network. This initiative is designed to drive innovation and accelerate the development of advanced RWA applications within the blockchain space.

The open call for the RWA Accelerator begins in December 2024. Up to ten startups will join a 3-month program, starting in March 2025, that focuses on RWA tokenization projects with targeted support and resources. The program will culminate in June 2025 at the Plug and Play Silicon Valley Summit, where startups will present their projects to Plug and Play and its network of investors and stakeholders.

"XDC Network already has a strong foothold in the RWA tokenization space. By establishing an enterprise RWA accelerator alongside Plug and Play, the network will gain a clear, strategic advantage that will greatly expand its reach and impact in RWA applications," says Billy Sebell, XDC Foundation Executive Director. "We are energized by Plug and Play's selection and onboarding process and look forward to working with the high-caliber candidates they attract to this program."

XDC Network is known for its cutting-edge blockchain technology and robust ecosystem in global trade and finance. The network has achieved significant milestones, including:

Integration with Securitize: XDC is one of only four networks working with Securitize, a leading provider of RWA tokenization solutions.

Support for tokenized treasuries: XDC hosts the $USTY token, representing access to a U.S. Treasury fund managed by BlackRock.

Trade Finance Participation: XDC is a member of the Trade Finance Distribution Initiative, which has set its sights on addressing the $5 trillion trade finance gap.

Involvement with ITFA: XDC has joined the International Trade & Forfaiting Association's Digital Negotiable Instruments Initiative.

Infrastructure support from Deutsche Telekom: Deutsche Telekom serves as an infrastructure provider, bolstering the blockchain's ability to support real-world asset (RWA) tokenization.

XDC Network has also led several key innovations, such as supporting some of the first trade finance tokens in 2022, and successfully converting a paper Bill of Lading to an electronic version in 2023. Additionally, in 2024, the XDC coin was successfully used to settle a transaction on R3's private Corda blockchain in a proof of concept.

"XDC Network, with its robust performance and leadership in RWA tokenization, is positioned to capture the next wave of the tokenized economy," said Maximillian Jungreis, Head of Crypto & Digital Assets at Plug and Play. "Being distinctly capable, connected, and still somewhat under-recognized makes XDC the ideal blockchain for this initiative. Their strategic partnerships with industry leaders like Securitize highlight the network's position and influence. This accelerator will drive enterprise adoption of RWA tokenization, providing startups with the resources to develop groundbreaking solutions. We look forward to collaborating with XDC Network and the exceptional startups that will join in this mission."

This partnership will foster the development of pioneering projects in RWA tokenization and contribute to the ongoing advancement of blockchain technology. Both Plug and Play and XDC Network are committed to driving innovation and delivering impactful solutions.

Plug and Play Selects XDC Network to Launch an Enterprise RWA Tokenization Accelerator

SBI XDC Network APAC, a joint venture with TradeFinex Tech, and SBI R3 Japan have successfully completed a proof-of-concept experiment that was previously announced in December 2023 as the JV’s first initiative.

The PoC demonstrated that value via digital assets can be transferred over different distributed ledger technologies (DLT), in this case, the XDC Network and the R3 Corda platform, as a form of payment to improve efficiency and facilitate inter-business settlement in trade transactions.

Furthermore, to deepen the collaboration between the XDC Network and Corda within the SBI Group and to expand the use cases of Corda Bridge, the ownership of the Corda Bridge used in this experiment will be transferred to the joint venture company SBI XDC Network APAC.

The partnership between the SBI Group and the XDC Network, which started on May 31, 2023, with the launch of the first domestic handling of the XDC cryptocurrency by SBI VC Trade, will enter its second year.

Through these initiatives, the partners aim to realize the construction of a new foundation that contributes to the efficiency and smoothness of inter-company settlements in trade transactions.
