How To Learn Blockchain From Scratch

It’s How You’ll Expand Your Programming Career

Learn Blockchain Programming From Scratch – No Coding Experience

9/10 devs don’t understand blockchain , but in the “why does this exist sense”.

“It’s slow”, “it’s useless” “it’s NOT”.

Everything we know about blockchain tells us it’s innovative, it’s in demand, and it’s changing the world. I can’t change your mind and how you feel about it, and honestly, I’m amazed you got this far down the page.

When you understand how powerful blockchain is. When you know it’s going to be a learning curve. When you can see how it’ll change industries. And you’re still reading, then there’s only 1 thing left to do.

From Zero To Blockchain Developer

Now, this is the step-by-step overview of knowing nothing about Blockchain to landing your first blockchain developer job. This can actually be done many people have learned blockchain development without prior programming knowledge.

Step 1: Obtain Cryptocurrency

Making a payment with cryptocurrency is the best introduction to blockchain because you will gain familiarity with how the technology works. By sending cryptocurrency, you will see what its like to create a wallet and initiate a transaction.

Of course youll need some cryptocurrency in order to do this, so you can purchase some on a website like Coinbase.com, or you can try this for free with fake cryptocurrency on an Ethereum test network like Ropsten, for example.

Step 2: Create a Wallet

Setting up your wallet, as explained earlier involves you installing the meta mask extension on your chrome and setting up your cryptocurrency account. You can hold the cryptocurrency on your public wallet.

Step 3: Follow a Step-by-Step Tutorial

Now its time to follow a step-by-step tutorial that will teach you the basics of how blockchain works, as well as the fundamentals of the programming languages. The easiest way to get started is to use the in-browser approach that I described earlier. You can use this guide to get started now with this method!

Step 4: Build a Real-World App

This is exactly what I teach you how to do inside The Blockchain Developer Bootcamp.

Step 5: Unguided Development
Step 6: Create Your Portfolio

Some People Reading This May Be Curious About Blockchain But Dont Have A Technical Background For Those Who Want To Start With Something Lighter Youve Also Written A Book That Is A Fun Introduction To Crypto For Beginners Can You Tell Us A Bit About That

Sure. Im the author of Strength in Numbers: A Novel of Cryptocurrency. Its a science fiction novel set in the near future at the University of Pittsburgh, where an English literature student discovers there may be a key to five Bitcoin hidden in her room. If she can figure out how to access it, her money worries will be over. Along with her friends, who are studying computer science and mathematics, she tries to understand how cryptocurrencies work. Its not a textbook at all, but along the way it gives a good grounding in not only how blockchains and technologies like Bitcoin and Ethereum work, but also how these might impact the world. I firmly believe blockchain technology is going to change the world, in lots of different ways! I also go into depth on that in aspects of the book, as part of the story.

Thanks Bill. We look forward to the first release.

What Inspired You To Write The Course

I wanted to teach blockchain from the very foundations all the way up to being able to produce distributed applications, blockchains and parachains. There are courses that you can take, especially at the university level, that focus on the theoretical side of cryptographics and mathematics, and there are courses that teach you how to use a particular blockchain technology, or write an application that will run on a network in a particular programming language. Its rare to find something that goes from the very basics all the way up to what blockchain technology is doing today and how to make projects that use blockchain technology on your own.

Big Companies Are Investing In Blockchain

How To Build A Blockchain In Python

Big companies like Amazon, Google, Starbucks, Walmart, and Facebook are all taking Blockchain very seriously.

Google’s Big Query service supports Ethereum smart contract analytics. This platform allows you to analyze Ethereum transactions you can look at smart contracts and others.

Amazon has their managed Blockchain service on AWS. On June 1st, 2020 Amazon announced they are looking for a patent in Blockchain for a supply chain.

Facebook also has its libra Blockchain, though they are facing some hurdles with the regulatory bodies, they are working hard to launch their own cryptocurrency.

Walmart also has its distributed letter technology, which they are also working on it’s undergoing research with the supply chain.

I have personally been to presentations where Starbucks showed a proof of concept for supply chain solutions within their business.

All these big companies are taking Blockchain seriously. They can’t afford to ignore blockchain!

What Does A Blockchain Developer Really Do

Sometimes it’s hard to explain what a blockchain developer is because there are so many things they actually do. Technically if your website development even touches a blockchain, you are already a blockchain developer. For example, the Shopify app from earlier, once you already have to integrate it with cryptocurrency, you’ve had a touch into Blockchain meaning you have to know something about it.

Lets list a few examples of what a blockchain developer might do. This is not a comprehensive list, and blockchain developers are not required to master each of these skills. These are just some ideas.

Creating The Genesis Block:

The genesis block is the first block created in a blockchain. Lets create a function that creates a genesis block for our blockchain and returns a new instance of the Blockchain type.

Add the following code in our Blockchain implementation in blockchain.rs:

impl Blockchain       // Create chain starting from the genesis chain.     let mut chain = Vec::new      chain.push)      // Create a blockchain Instance.     let blockchain = Blockchain       blockchain   }}

In the code above, we did the following:

  • Added the genesis_block we created to the chain in our Blockchain type.

  • Returned an instance of the Blockchain type.

In the genesis_block instance we created, notice how we set our previous_hash key to an empty string value ) thats because there would be no previous block since the genesis block is the first block in the blockchain.

Also notice we made the hash of our genesis_block to be an empty string thats because we havent calculated the hash value for our genesis block yet.

So What Happened Here

We created a new cryptocurrency based on the blockchain and named it BlockGeeksCoin. By invoking this new object, I activated the constructor, which in turn created the Genesis block automatically.

We simply added two more blocks to it and gave them some data.

It is that simple.

Thats it for this milestone. Lets look at the action steps. It is very simple but it definitely isnt easy:

  • Get educated in one of the many blockchain-friendly languages like C++, Javascript, C#, Go, etc.

Become A Blockchain Developer Milestone #: Learn The Process

It is pretty surprising to see how many budding developers have not had any real-world first-hand experience with cryptocurrency at all. How can you possibly innovate and improve upon a platform when you have not used it even once?

It is strongly recommended that you start getting acquainted with the system today.

Go to Coinbase or any other exchange that you are comfortable with or is accessible in your country and buy some coins. You dont need to create an extensive portfolio straightaway, just buy a few coins and see how the whole process works.

It is extremely straightforward. Since you are not going to be buying a lot of coins then simply use a basic online wallet.

These wallets are the easiest to use among all. The creation is super simple because its basically creating your own account on any of the exchange services. Furthermore, you can access this wallet from any server or any device in the world as long as it is connected to the net. Having said that, there is one big problem when it comes to online wallets. Your private key is going to be saved on another server. This is basically like serving up your key to hackers on a silver platter. Do NOT use online wallets to store huge amounts of your money. Store the bare minimum that you need for exchange purposes.

We are bringing this section to a close here, the tough part starts from the next milestone.

Your action steps are here:

  • Learn how the exchanges work.
  • Get acquainted with wallets.

How To Build A Blockchain App The Hard Approach

Alright! You got me! You do not want the easy way, but want to learn blockchain the hard way. Do not worry, as, in this section, we are going to create a todo list app using Ethereum smart contracts.

Blockchain Application Workings

Before we dive deep into creating a blockchain app, lets try to understand how a blockchain application would work in the first place.

To understand that, lets take a look at how a simple app works. Any app that works on the internet is rendered on the users computer using a browser or a dedicated app on windows. In any case, it requests the server for the pages or information, which is then rendered on the users computer.

In the case of the web application, everything is centralized. This does offer some benefits however, it leaves a lot to be desired when it comes to security. Blockchain apps work entirely differently. Everything is decentralized, including the code and the data that is stored in the app.

Smart Contracts

The key here is the smart contract. A smart contract facilitates the app itself. It contains all the code that makes the app work. It also automates the process and ensures that it works as intended. In our tutorial, we are going to use smart contracts to write the different functionalities of the to-do list.
