Light Paper: The Identity Registry

Decentralized PayString Provider on the Internet Computer


The Identity Registry is an avant-garde initiative, specifically designed as a decentralized PayString provider, operating on the Internet Computer. This venture represents a novel concept within the digital finance realm, blending elements of unique digital identifiers with non-fungible tokens (NFTs).

The primary service of The Identity Registry is offering PayStrings as Non-Fungible Tokens (NFTs) through direct sales and auctions. Each PayString, represented as an NFT, is not just a simple payment ID but also a unique asset that users can own, trade, and monetize. This system leverages the inherent advantages of blockchain technology, offering enhanced security, transparency, and the potential for appreciation in value.

Vision & Mission


Our vision is to be the foremost decentralized PayString provider, instigating the confluence of payment identifiers and non-fungible tokens. Through the power of the Internet Computer and the Service Nervous System, we envision a world where financial identities aren’t merely identifiers, but unique assets with potential value growth. We aspire to create a future where everyone has equal access to a decentralized, transparent, and innovative digital financial ecosystem.


Our mission at The Identity Registry is to redefine the digital financial landscape by enabling the acquisition, trading, and auction of PayStrings as NFTs. By harnessing the power of the Internet Computer and the Service Nervous System, we aim to establish a decentralized, secure, and transparent platform where digital identities evolve into valuable, tradable assets, facilitating interoperability across diverse financial networks.



PayString is a universal payment identifier that provides a single ID for users to receive payments from any network. It's akin to an email address for payments, and it ensures interoperability across different payment networks.

Internet Computer

The Internet Computer is a decentralized computing platform created by Dfinity, which aims to extend the functionality of the public internet. It allows developers to build and host software systems and data directly on the internet itself without needing traditional servers or commercial cloud services.

Non-Fungible Tokens (NFTs)

NFTs represent unique items or pieces of content on the blockchain. They have gained considerable popularity due to their ability to prove ownership and authenticity of digital assets.

The Identity Registry's Offerings

PayString as NFTs

The Identity Registry offers a unique approach by selling PayStrings as NFTs. Each PayString ID is uniquely associated with an NFT, which signifies ownership of that particular PayString. When a PayString NFT is sold or auctioned, the new owner is given control of the associated PayString, providing them with a unique, interoperable payment ID across various payment networks.

Auction Platform

The Identity Registry incorporates an auction platform, which allows the trading of PayString NFTs. Users can bid on desirable PayStrings, and the highest bidder will be assigned ownership of the PayString. This promotes a fair and transparent method for the allocation of valuable PayStrings.

Direct Sales

For users seeking a quicker purchase process, The Identity Registry provides a direct sale option. Users can directly purchase PayString NFTs at a set price.

The Technology Stack

The Identity Registry is built on the Internet Computer, leveraging the features of a decentralized computing platform, ensuring data security and privacy. The Identity Registry uses smart contracts to manage the ownership and transfer of PayString NFTs, thereby ensuring the process's transparency and security.

Use Cases

Digital Identity: A PayString can be a representation of digital identity. Owning a PayString NFT means having a unique digital identifier across financial networks. Asset Ownership: PayString NFTs can be bought, sold, or traded, just like other digital assets, providing an alternative investment avenue. Interoperability: With PayString NFTs, users can send or receive money from any payment network or currency, enhancing interoperability in the digital financial ecosystem.


The Identity Registry is at the forefront of digital financial innovation, bridging the gap between traditional finance and the crypto economy. By offering PayString as NFTs, The Identity Registry not only provides a unique digital identity across payment networks but also introduces a new asset class in the NFT space. Through this initiative, The Identity Registry is pushing the boundaries of what's possible in the DeFi space, contributing significantly to the ongoing digital finance revolution.
