Would it be possible for an educational institution to issue wrong certificates because someone knows somebody there?
This would be possible because there are many kinds of people who do those evil deeds. But if you want more to learn about the project you are into. Search it on the website for legit platforms. Surely it will be listed there if its fake or legit.
Not saying that the project itself is fake but there is a real possibility that fake educational certificates get issues on the blockchain and that would be bad as anyone would trust them.
That is, you want to say that maybe this project is a scammer and there can be fake education certificates? This can severely defile the status of the Crypto-currency.
That's why it will be based on blockchain, I don't think any university or institution will still have the guts to manipulate and give certificates when all the transactions will be logged on the blockchain. That means sooner or later, their wrong deeds will surely comeout, the platform can also be used to verify certain certificates for validity first.
