How To Get Started With Blockchain

From Zero To Blockchain Developer

How to Get Started in Blockchain With No Experience

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

Con : Criminals Utilize Cryptocurrency

Because of blockchain technologys anonymity, criminals were some of the first groups who used cryptocurrency. People would use bitcoin to purchase and sell illegal goods on underground marketplaces like the Silk Road. Blockchain cryptography enables both parties to retain their privacy, but the criminals have certainly taken advantage of the system.

Interacting With Our Blockchain

You can use plain old cURL or Postman to interact with our API over a network.

Fire up the server:

$ python blockchain.py* Running on http://127.0.0.1:5000/ 

Lets try mining a block by making a

GET

with a body containing our transaction structure:

If you arent using Postman, then you can make the equivalent request using cURL:

$ curl -X POST -H "Content-Type: application/json" -d ''"http://localhost:5000/transactions/new"

I restarted my server, and mined two blocks, to give 3 in total. Lets inspect the full chain by requesting

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.

What Is Blockchain Technology

How To Get Started With Crypto And Blockchain

At the center of Bitcoin and other cryptocurrencies is a blockchain. Simply put, the blockchain is the ledger maintained by the computer network. Just as VISA or banks have separate ledgers, each cryptocurrency has its own blockchain ledger with its own native currency and payment network.

Think of blockchain technology as an interactive database in the cloud. Anyone can make changes to the database if they have the keys . These changes are permanent and timestamped. And since the units being moved on the blockchain are provably unique, they can represent any value we assign to them in the physical world. In Bitcoins case, value is determined by the market buying and selling at exchanges all over the world.

Besides replacing the need to trust governments or banks for money and payments, this technology has many other uses including IDs, gaming assets, event tickets, voting, supply chains, sensitive records, borrowing and lending, and so on. That is why so many people are excited about cryptocurrency.

Getting Started With Blockchain

Transparency, immutability and security, which characterise blockchain technology, have propelled it into unthought of domains. From being a means of carrying out decentralised monetary or asset transactions, it has now been adopted in areas like healthcare, real estate, supply chain management and energy distribution.

Blockchain is a peer-to-peer ledger system that allows transactions among peers without any centralised authority. The peer-to-peer network is completely decentralised because each peer carries a copy of the ledger. The ledger can be a complete copy or the minimal copy required for it to stay connected and functional for the network.

To ensure consensus across transactions, consensus methods like proof-of-work, proof-of-stake, etc, are used. Also, each transaction is completely secured with the help of advanced cryptographic algorithms. Clearly, the whole blockchain mechanism is used to benefit from its trust, immutability and transparency. The idea is the complete opposite of centralisation. In short, it is a network with peers capable of doing transactions without any centralised authority. This simple idea is single-handedly changing how industries work.

Blockchain architecture for beginnersNow that we have some idea of how a blockchain functions, it is time to learn about its architecture.

The key components of the blockchain architecture are:

  • Transactions
  • Mining
  • Consensus

To understand the differences between the three, just go through Table 1.

Looking Forward: The Future Of Blockchain

How to get started in blockchain with IBM’s Eileen Lowry

Along with technological advances like AI, Blockchain for the last two years has grown tremendously. Records, Contracts, and Transactions are the core structures of our Financial, supply chain, and legal systems, among others. They protect assets and provide the basis for an organization’s decisions. But in this era of technological advances, we have not paid much attention to coming up with better tools and ways to manage these basic structures, even as information is turning digital. Blockchain provides the solution!

Here are the ways Blockchain will possibly shape the society in the next few years:

Government leaders, leading business organizations, and technology enthusiasts are coming out in large numbers in support and funding of Blockchain. Blockchains future is definitely optimistic.;

Building Your Own Projects

You should now be comfortable with most of the tech whats left is to start building stuff and going deeper into the blockchain community.

First, start building your own projects. If theres some great idea that youre excited about, go build it, and convince others to hack on it with you! If you dont have an idea yet or arent comfortable getting your hands dirty, there are many high-quality open source projects that welcome contributions. OpenZeppelin might be a good place to start for smart contracts.

Better yet, Id recommend starting by finding an actively developed project that youre a fan of. Get on their Slack or Rocketchat the devs are usually readily accessible. Tell them youd like to contribute and ask for some small tasks .

Note that while Ive been focusing on protocols and smart contract development, blockchain companies need web developers to build their core functionality. These roles will often require interacting with blockchains, so its essential to have a good mental model of how blockchains work but for many engineers at blockchain startups, most of your work will be in building a Python webserver, or designing a React frontend, and interacting with the blockchain may be a small part of that job. You dont have to specialize in smart contract development in reality, thats only one part of a working blockchain stack.

Why There Is So Much Hype Around Blockchain Technology

There are plenty of claims regarding Blockchains actual potential. The distributed ledger database has been regarded as a game-changer, with many individuals staking their reputations and fortunes on it. Claims have been made about its ability to aid in increasing transparency in the health and manufacturing sectors, as well as reducing fraud for enterprise applications such as financial systems or for that matter, any system involving centralized control. Actualizing Blockchain innovation in the thriving shared economy could diminish the requirement for focal control.

Blockchain proves its capability by bringing simplicity and immutability to the process of accessing information. The potential for smart contracts, as well as the opportunity to make new business models, should inspire business heads to review the fundamental aspects of their business in the context of Blockchain. Features like trust, immutability, privacy, and reliability make Blockchain appropriate for every industry. Blockchain technology is going to be a relevant subject of conversation for many days to come.

Using a blockchain course or certification program, you can easily learn about all the previous steps I covered in this guide. So, you get to learn about other business platforms. More so, you will learn how your company can benefit from it.

Moreover, use this as the perfect revenue-driving force. So, I will highly recommend you to try out our blockchain professional certification course. The course is meant for any professionals in this field or anyone who is interested in learning about it as well.

Which Programming Languages Are Required For Blockchain

How to get started with Blockchain

Here are some of the most popular programming languages for blockchain development. This is not a comprehensive list, and blockchain developers do not necessarily need to know all of these languages. However, there are some common examples:

  • Solidity
  • Rust
  • C++

If youre brand new and dont know where to start, I recommend learning Solidity and JavaScript. It’s usually necessary for a developer to learn front end languages and back-end languages. In this case, Solidity will be the back-end, while JavaScript will be like your front end. Unless you know exactly what you would like to do, it’s best to focus on these two.

Python is also a powerful language but you won’t be able to use it to build mobile apps or clients that have applications that easily.

Go, rust and C++ are for more low-level infrastructure and different smart contracts platforms.

Solidity

Solidity is the main programming language for creating smart contracts on The Ethereum Blockchain. Hence it’s highly recommended you learn Solidity. Solidity is a straightforward programming language with influence from C++, Python and JavaScript.

JavaScript

if you don’t have a JavaScript background, I recommend learning JavaScript for blockchain development since it plays several crucial roles like developing user interfaces, testing smart contracts, creating backends, and writing scripts that run against the blockchain.

Where Can I Start Learning Blockchain

Like so many knowledge quests, there are plenty of avenues to your final destination.;David Araklien, CTO at Bitstocks, suggests that GitHub may be your best bet: If you are already a developer, then you can directly check the source code, thats another way of looking at the mechanics of blockchainhow they work and how they behave.

Bitcoinsv.com;is a great starting point with general overviews of the Bitcoin SV technology and ecosystem as well as pointers to common tools use by developers in the space,;Steve Shadders, CTO of nChain, told Dice.;

Meanwhile,;James Howard, research scientist at Johns Hopkins Applied Science Laboratory, advocates for more traditional forums like Udacity and Coursera:

The best way to learn about blockchain is to pick up a solid grounding in public key cryptography and cryptographic hashes. These two technologies underlie all blockchain platforms, though each uses different algorithms. That can be learned online with courses from;Stanford through Coursera;and;Udacity. Both will give a kind of grounding. While it is not important to learn the specifics of any algorithm, but concepts like the web-of-trust, how cryptographic hashes protect data, and key hygiene are the ones necessary for blockchain. It can be hard to learn, depending on your level of experience. If you have taken some computer science courses, then it will be a lot easier.

Is Blockchain Easy To Learn

Araklien underscores something key: knowing how blockchain works doesnt mean you understand how to apply itor even where. If you have development experience, you can pick up the basics very quickly, but the problem with blockchain is that it brings together multiple subjects into one, he said. Once you start scratching the surface, you see different things behind the simple mechanics like economics, politics, finance, data security, etc. It becomes an endless stream of other related subjects and knowledge that you can learn. The mechanics of the system is merely the top layer.

But I also think you could pick it up if you have other skill sets such as math, computer science, economics, or finance, he added. There are a variety of foundational skills that could be built upon. Its helpful to have some development skills as most of the online tutorials are written by developers, because the original Bitcoin/blockchain project itself started as a development project.

Dr. Stylianos Kampakis, CEO of The Tesseract Academy, points out that blockchain education requires a bit more forethought than simply how you want to apply it.;Learning blockchain is like learning any other skill in technology. Right now there are multiple competing blockchains and frameworks, some of which support established languages and some others have their own language .
