Soulbound Token (SBT)
"Soulbound Token (SBT)" is an important term in the Web3 sector, referring to a "non-transferable Non-Fungible Token (NFT)" that is linked to a specific individual or entity and, once issued, cannot be bought, sold, or transferred. Its potential is being noted as a new form of digital identity that records and proves an individual's digital attributes and achievements on the blockchain.
- Non-transferable NFT: A token that cannot be bought or sold, permanently linked to a specific wallet.
- Digital Identity: A foundation for proving an individual's reputation and achievements, such as academic history, work experience, qualifications, and community contributions.
- Building Trust in Web3 Society: Holds the potential to build trust mechanisms not only for traditional financial systems but for society as a whole on the blockchain.
Why Is This Term Gaining Attention Now?
In the traditional Web3 world, anonymity was high, and mechanisms for digitally proving individual trust and reputation were insufficient. SBTs are expected to solve this challenge by digitizing an individual's "credit" and "achievements"—such as academic history, qualifications, community contribution levels, and event participation history—and recording them on the blockchain. This is anticipated to contribute to the realization of a more trustworthy Decentralized Society (DeSoc). While NFTs hold asset value, SBTs have the potential to digitize non-financial values like personal reputation and qualifications. Our editorial department is also focusing on this as a new foundation for Web3 society.
Practical Conversation Example and Usage
Person A (DAO Member): "Anyone can participate in this DAO's governance vote, but we really only want to give voting rights to those who've contributed. How can we do that?"
Person B (Web3 Developer): "How about using SBTs? We could issue non-transferable SBTs based on past contributions and activity, and only grant voting rights to those who hold them. That way, the opinions of true community members would be reflected, right?"
Similar Concepts and Differences from Other Terms
SBTs are a type of NFT, but the most significant difference lies in their "transferability."

| Primary Use Cases | Digital identity, credentialing, academic records, reputation systems | Digital art, collectibles, game items, property deeds |

Frequently Asked Questions (FAQ)
Q: How are SBTs issued?A: SBTs are issued directly to an individual's wallet by a "Soul" (issuer) such as a specific event organizer, educational institution, or DAO (Decentralized Autonomous Organization). For example, a university might issue an SBT as a diploma, or a DAO might issue one as a reward for members who complete specific tasks.
Points to Note, Etiquette, and Misuse When Using
Since SBTs are extremely important as an individual's digital identity, their management requires utmost care. Once issued to a wallet, they cannot be transferred, so if an SBT is mistakenly issued to the wrong wallet or if the wallet's private key is lost, it becomes very difficult to recover. Furthermore, as SBTs become more widespread, there is a risk of fraudulent issuance by malicious parties, as well as potential discrimination or prejudice based on the information recorded in SBTs. Therefore, issuers of SBTs must ensure reliability, and recipients are required to have the literacy to verify the authenticity of the information.
