Soulbound Tokens (SBTs) introduce a new way to verify achievements and credentials on the blockchain.
By Gavin Wood on
Soulbound Tokens (SBTs) are non-transferable NFTs that represent credentials, achievements, or reputation on-chain.
How SBTs Work
Unlike regular NFTs, SBTs cannot be sold or transferred, making them ideal for:
On-chain resumes (e.g., proof of education, work experience).
Reputation systems in DAOs.
Access control (e.g., exclusive event passes).
Vitalik Buterin introduced the concept of SBTs in 2022, and since then, projects have been exploring how they can revolutionize decentralized identity.
