There is a very interesting use case in blockchain, a use case that will allow our professional and academic career to be certified in a safe way, we’re talking about blockcerts.
For some time now, MIT has launched a standard for managing certificates between people. In particular, this standard allows a university or ministry to sign and therefore accredit a degree. In this way, when a person refers to a certificate that has been obtained, we can know if a university, ministry or entity, have proven that this certificate is correct.
How blockcerts works ?
The Blockcerts code is free, so anyone can develop applications from Blockcerts.
Blockcerts provides a system where credentials can be validated by anyone, without the need for third-party intervention.
The Blockchain network, as always, will work as a trusted provider, verifying credentials in a secure way.
The really interesting thing about blockcerts is that universities can validate the issued titles instantly. In this way students can credit these titles without needing any other element than the hash of the transaction.
Blockcerts use 4 types of entities:
Universities create digital academic certificates that contain a person’s information (their achievements, skills, characteristics, notes, etc.) and register it in Blockchain.
This process can be complex due to the transformation of the whole information into a hash that serves this purpose. For that situation, BTCAssessors recomends to use and abstraction like merkel-tree.
Certificates are compatible open badges, which is important, because there is a whole community of “open badge” issuers that would work with Blockcerts, and because “open badges” is becoming an IMS standard.
Anyone can verify that the certificate has not been tampered with, that it has been stamped by a particular institution for a specific person.
Users can securely save their certificates and share them with others (for example, employers or universities).
This point needs the users to have some knowledge of the signatures processes, because they will use blockchain for writing.
What is the future of blockcerts?
Well, it seems clear that this standard will be used very soon in a massive way. We have many examples where the administrations are interested in blockcerts. Some in Andorra or Barcelona.
What usually happens in these cases of “hype”, is that many companies get on the train, but when the truth is, there are some challenges that will make it only implemented by companies with experience and high added value.
…sooner or later… they will appear companies offering cloud SaaS open-badges services.
Then users will have the ability of share their certificates to any conected device…
Then… certificates will conquer other places like gyms, trainings, etc..
