Vitalik Proposes Soulbound Tokens as Web3 Credentials of the Future

"Buterin’s soulbound tokens (SBTs) are non-transferrable NFTs held by unique crypto wallets called Souls. In the paper Buterin co-authored to introduce the concept, he described multiple ways SBTs could be used – as university degrees, education credentials, and as web3 credit scores. Instead of a web3 hiring manager calling up your alma mater or checking LinkedIn, he could check your on-chain resume for a transaction showing the university’s Soul transferring you an SBT. As Buterin writes, “‘Souls can encode the trust networks of the real economy to establish provenance and reputation.” SBTs have the ability to decentralize power away from major institutions and companies and towards the users – instead of a private database owning your credentials, you would own the keys to your credentials.

Not particularly bullish on this. Not sure this problem actually exists... also, people today use a lot of different wallets, and a concrete and adopted solution to have a "unique" on-chain identity doesn't exist today.
