Well.. this articole has some points but is not 100% fair or correct. The value of distributed ledger (aka blockchain) is given by the fact that you can find the latest version of a record in a decentralised way. This is usefull outside cryptocurencies (even for university diplomas you need a good mecanism for revocation). You can do revocation with a centralised system but a decentralised version could actualy imprive security and privacy (not with blockchains alone you need encryption and other cryprographic tools)
- p4bl0 5y agoThere are other ways of having a distributed immutable ledger than a blockchain, if you don't have the constraints of a decentralized adversarial context. You don't have this context for diplomas. Also, neither revocation nor security and privacy does seem like good examples of what a blockchain would allow that a non-blockchain based approach wouldn't.
- errantmind 5y agoThat is a big 'if'. The adversarial context is everything. As for diploma's, I'm not sure what your point is. There is nothing decentralized about them.
- p4bl0 5y agoThe adversarial context is everything, but it doesn't exist in most case, because the blockchain is not self sufficient, it needs an external authority to make what's written on it relevant. As for diplomas, I didn't choose this example at random. A lot of startups are trying to sell exactly that. I've been approached myself multiple times about that. And some higher education institutions already do it…
- boublepop 5y agoAmazing, we might finally be able to solve the great university diploma verification problem. It’s really held back society that we haven’t been able to verify diplomas issued by centralized trusted institutions in a decentralized trustless fashion. /s
