II Soul-Bound Tokens (SBTs)

Soulbound Tokens (SBTs) are a novel class of digital identity tokens that encapsulate an individual's or entity's attributes, capabilities, and achievements [3]. While they share a technological foundation with Non-Fungible Tokens (NFTs) in utilizing blockchain, their defining characteristic is non-transferability. SBTs transcend the conventional scope of NFTs, which are often associated with financial value and status, to represent unique and non-transferable identities. These tokens are intrinsically linked to a blockchain network, where they securely store a spectrum of personal and professional data, ranging from age and educational background to health records and career milestones.
