The growing popularity and widespread adoption of non-fungible tokens (NFTs) have created a demand for constant innovation and improvement in the technology behind them. One such advancement is the ERC-7231 token standard, which aims to revolutionize NFTs by introducing new features and capabilities. ERC-7231 is an extension of the widely used ERC-721 token standard, which serves as the foundation for most NFTs in existence today.
ERC-7231 introduces the concept of identity binding, where multiple Web2 and Web3 identities can be securely linked to a single NFT. This allows for the creation of Soulbound Tokens (SBTs), which are non-transferable NFTs used to represent reputation, credentials, or achievements. With ERC-7231, users can now have verified information from platforms like Twitter, LinkedIn, Discord, and on-chain wallets linked to a single NFT. This enhances the trustworthiness and robustness of a person’s online identity and enables greater interoperability between different platforms.
ERC-7231 enables the portability of important information, such as professional certifications, gaming achievements, or community contributions across various platforms. This means that users can easily carry over their credentials and accomplishments to new projects and communities without the need to constantly prove themselves again. Unlike traditional Web2 models, where user data is often collected and used without their control, ERC-7231 puts users in charge of their identity information attached to their NFTs. This aligns with the decentralized and user-centric nature of blockchain technology, giving individuals more ownership over their personal data.
The possibilities of using ERC-7231 go beyond NFTs. Some potential use cases include targeted airdrops to holders of specific SBTs, permissioned access to Web3 platforms based on verifiable credentials held as SBTs, and the potential to improve credit scoring models by integrating verifiable on-chain activity and reputation. The driving force behind ERC-7231 is CARV, a Web3 data infrastructure company, focused on creating a more secure, trustworthy, and user-controlled online identity system leveraging blockchain technology.
ERC-7231 has gained traction within the Web3 space, with more projects and communities recognizing its benefits. As the adoption of this standard increases, we can expect to see more innovation and potential for growth in the NFT ecosystem. ERC-7231 is an exciting development in the world of NFTs that has the potential to transform how we perceive digital identity and user data. By linking multiple identities to a single NFT, ERC-7231 offers a secure, portable, and user-controlled solution for managing personal information.
