Build a Blockchain with Python & FastAPI

In this video we're going to look at how to build a blockchain using Python and then access it using an API built with FastAPI.

The finished code can be found here:

learned a lot of new stuff, fastapi and blockchain concepts were really well coded, awesome tutorial. 😃

[ANDIBAUER]

hey Rithmic, very nice video! I hope your chanel grows fast! Wish you the best!

[joefelx]

Your code looks really clean and neat👍

[plashless]

Amazing. Bro.
Really Helped me a lot.

What a great idea for a series. Keep up the efforts!

Just curious, how many blockchain projects do you have?!

[absinth]

very nice video ! which completion tool are you using and theme/fonts as well?

[sanyk]

Thanks for the FastAPI content, subscribed. Don't stop posting new video's related to FastAPI.

Just curious, what would happen if this blockchain is being mined from different nodes almost at the same time... How reliable would this system be un ensuring that no 2 blocks have the same indexes or it doesnt crash

Great video. I am getting AttributeError: module 'blockchain' has no attribute 'Blockchain' when running the bc = blockchain.Blockchain() do you have something else imported which is not visible in the script?
Cheers

I'd love to see someone actually launch a python blockchain, for real, and document it
I think it would make for a really interesting series. I've mostly been curious to see more python-based dapps

I'd love to launch a few daps but have had trouble finding anything beyond hello world (even among paid content)

Block chain architecture seems surprisingly simple from watching this.

can you help me, how to implement blockchain p2p network on considering 5 computers using python program

hi Rithmic, thanks for a wonderful sharing with code. I have 2 questions: Q1. Why you do not include the Block hash in the the Block structure?

Q2. When you do Blockchain validation by checking the previous_hash etc, why do you need to do the Proof-of-work again?

The Nounce should be solved once and then the Block hash is generated. We should not need to run POW again - which is a lengthy operation - during verification.

Appreciate your reply. thanks.

This was a really great tutorial on a proof of work blockchain, do you think you could do one on a proof of stake blockchain as well?
I've seen quite a few tutorials on proof of work blockchains (this was the best so far), I've yet to find one on proof of stake.

Hey, @rithmic is it an Ethereum blockchain? Can I add a smart contract with it?

[csouravchowdhury]

Bro what is that u are typing at 0:26?

[Kos]

bro thanks for video. but repsonally I'm confused. there are a lot of information for me :D pls make video about web3 !!!

[eugenetsukerman]

And blockchain actually is being stored on the server?
