Nice explanation by the way. So What is the difference between API and RPC ?

emmanuelsahrsewah

It seems similar like REST, if we write our calculation functions/actions in another server with REST architecture and then we'll get endpoints to call and get the result.
Then why we need RPC?
Thanks!

I'm really glad that I found your course on Udemy. Your way how to explain API is remarkable :)

vovaka

What a clear explanation! I like your presentation which used database API as a comparison. That makes RPC API concept clear.

Wow thanks for making this video, it really solidified my understanding of RPC!

What about if the function is in our computer, but not in the same program? I mean, yeah we could use a shared library in the case of desktop programs but, what about if it's a Chrome extension trying to communicate with a binary host running on the same computer. What type of connection would they use for the fastest communication?

amazingly delivered lecture. thank you.

Misleading title, It should be what is an API. You haven't explained RPC.

atulram

So this video explains what an API is very generally, but says nothing about RPC specifically and how it might differ from the better known REST API, for example. Unfortunately that means I learned nothing from this video. It is very well explained and you do a good job, but a more appropriate title would've saved me this time.

Can we say that RPC is equivalent to DelegateCall in Solidity (Run Code or logic of another contract but use the storage of the calling contract) ?
