Hi there, given that this course dates back to 2018 (thats millenia in blockchain according to Ivan’s own words) and the fact that EY is exploring with public blockchains, is it still necessary to make the Hyperledger part of the course to graduate?
Shouldnt you put this content as optional now?
please anyone respond
To graduate or finish the course, yes, it is need it.
Now in terms of: Is Hyperledger still important? We could said that yes, it will be still used to share common data between companies (private), let’s said Amazon want to use blockchain for an specific use case on their delivery system, maybe just to communicate data between their different servers of some kind of internal operation between them.
But in the other hand, Ivan suggest that companies should explore a use case for themself on public blockchains, let said they could implement a public payment of the own company on a Smart Contract in Ethereum… This will give another functionality for the company in terms of payment options. And Hyperledger could be used for internal operations.
If you have any more questions, please let us know so we can help you!
