Adding Transactions to the Blockchain: Implementation - Blockchain In Rust #05: Transactions 2

[@salad7389]

Loved the series, would love to see more related videos!

[@annwang2990]

This video is a treasure! I love how you explained things so straightforward and clear! It is the best teaching video. Looking forward to see your smart contract video.

[@yashainu6047]

totally agree!! he uses the simplest implementation of rust code and explains the definition of Block, BlockChain, and Transaction and their relationships very clearly. This really helps me have a good beginning of the tour of Blockchain! I am also looking forward to the smart contracts!!!

[@김화겸-y6e]

Thank you so much!! I really appreciated this all lectures!! Please do make some more like these videos please!! You are very talented to educate this way

[@gurejalectures]

Never stop sharing this knowledge. .. i appropriate you bro

[@GeekLaunch]

Thank you! :D

[@Nothing-cx4jt]

This is the best one so far on building a blockchain using Rust. Love the way you explained things. Also your coding style

[@jeremyallam2351]

This series is great! Thank you for posting it. Any idea when/if the smart contracts video is coming?

[@jixs4v]

Hey, did you drop the smart contracts video? Is it coming soon? If it is, looking forward to it!

[@davidmoradi6390]

This is amazing. keep up the good work.

[@GeekLaunch]

Thanks, I plan to!

[@tolumideshopein]

Thank you so much for this Jacob. When do you intend to continue please 😊

[@satarius9941]

I like the way how you talk and educate, please for the love of god or whatever your thing is just get up and do the next video, much love and thanks for the all the fish.

[@phillipmektiev5063]

Really cool video! Can't wait for smart contracts!

[@rad1m]

Great stuff man! I've been looking for some tutorials for Polkadot Smart Contracts and even this is something else, it's a great start. Practical explanation of Rust and how is blockchain working.

[@shirshak6738]

will be waiting for next vids :)

[@GeekLaunch]

Smart contracts, coming soon! :D

[@mahmoudfathy2074]

I love these vids man, I am new to Rust I thought it will be productive to learn Rust through a concept that I am familiar with like blockchain which also enforces using the capabilities of the language. But I am did not expose myself to smart contracts and that makes me wait for your video now, Hope so 😃

[@GeekLaunch]

Ach, I'm so sorry I've been so tardy releasing the next video!! It's been like 6 months. :( I was very busy with school so I had no time! I still plan to make it... sometime...

[@mahmoudfathy2074]

@@GeekLaunch hehehe yeah it's been really 6 months, it's totally fine though, you can write a short teaser-like article about it if you already have the code, then you take your time to make a verbose video much later.

[@GeekLaunch]

I think that's a good idea! I'll do that 😊 Thanks!!

[@mahmoudfathy2074]

You're the one to be thanked for your awesome work

[@jasonxrowland]

Great work! Looking forward to the next video

[@GeekLaunch]

Haha, I'm in the process of moving. I intended to get the next video out sooner but life got in the way. Everything is prepared, I just have to find the time to sit down and hit record.

[@hedgehog826]

Amazing series! any chance you will release that next video?

[@ycemilk]

Are you going to share another video about making blockchain in Rust? If it's unfinished, please make videos, you produce great content. Especially about the little-known Rust.

[@jchaptter]

Great video ! This should get way more views !!

[@GeekLaunch]

Why, thank you! I've been trying to do a little extra promo; maybe I need to do more.

[@jchaptter]

@@GeekLaunch I shared it on twitter and reddit, let's hope it help.

[@GeekLaunch]

OMG thanks so much! ♥️

[@luisnegrao5951]

Here i am in 2022 wondering if you would like to continue this series XD

[@brendanarsechter8117]

Are there any plans do keep working on this series?

[@mehradkavian8017]

Amazing series. Although I think you explained much better in previous videos. for example, I don't understand why you &input_hashes - &self.unspent_outputs in your blockchain.rs file. Anyhow, keep up the good work!

[@adam-the-dev]

Still waiting on the smart contracts video!

[@InMemoryOfNeo]

we already memorized your name is jakob :D

[@vishalkulkarni3977]

i think coinbase.output_value>total_fee {error} not coinbase.output_value

[@liucharles2973]

want next video! thanks

[@shirshak6738]

do we still need to use crate:: things ? I think extern crate etc are optional now ?

[@GeekLaunch]

So, `crate::` syntax is new in 2018 edition, I believe. `extern crate` is still necessary if you want to use macros from the crate.

[@GeekLaunch]

See doc.rust-lang.org/edition-guide/rust-2018/module-system/path-clarity.html

[@BoaConstrictorStyle]

Hi! Thanks for the educating lectures. I would like to ask if there is an example that evaluates !(&input_hashes & &block_spent).is_empty() to true? github.com/GeekLaunch/blockchain-rust/blob/master/src/blockchain.rs#L65 I tried several examples and never got this line executed.

[@GeekLaunch]

Oh, geez, sorry. Totally missed this comment. So this would (should?) get executed if you try to spend the same input twice in the same block. IDK, maybe I messed it up? I think that should work...
