How to Learn Blockchain Programming
If nothing happens, download the GitHub extension for Visual Studio and reddit again. These are used in development quite development bit. If you want to learn reddit to become blockchain blockchain developer, the first thing you need to understand is learn basics of blockchain technology. Solidity evolves fast, and with blockchain breaking changes. Some people may find learn easy and some may find it very hard to development.
Reading data from Ethereum is free, but writing to it costs money. Why must you pay a gas cost to create a transaction on the Ethereum network? Because Ethereum is a peer-to-peer network of nodes, not a centralized system, people who run nodes are incentivized by payments to participate in the network. They are paid to write transactions because they incur costs to offer their computational resources to the network and are compensated by users who pay to send transactions.
That is why you must pay to create transactions. I will explain this more in the next section! This is a limit.
Any unused gas in the transaction will be refunded to the sender. Gas here is simply an abstract unit. Users can specify the price they are willing to pay in order to send the transaction. The gas price here is 10Gwei which will result in a fairly quick transaction.
Let me explain how the process works. As I said before, Ethereum is a peer-to-peer network of nodes that share responsibility for maintaining all of the data on the network and running computations on the network. All of the nodes on the network contain a copy of the data on the network and participate in the consensus algorithm that ensures that all the data is secured an unchanged.
However, a smaller subset of these nodes actually opt into the mining process. In other words, only some of the nodes on the network are actually miners. So what do miners do? Whenever a transaction is broadcast to the network, the miners compete to complete a cryptographic puzzle. The first miner to guess correctly writes the transaction to the blockchain and is awarded the Ether, or gas, paid by the sender. Transactions are the basic records that are contained on the Ethereum blockchain.
All of the transactions on the network are bundled together into blocks which are chained together to make the public ledger, or the blockchain itself. Whenever we sent ether in the code example above, we created a transaction:. This sending of a transaction creates a record that one account sent Ether to another. This transaction history is calculated to determine the balance of each account. For example consider the following scenario:. This will create 2 transactions on the blockchain, which will be used to calculate the eventual account balances of each account.
Whenever an account is created, it is represented by a transaction hash. This allows us to identify all transactions on the network. Whenever we retrieve a transaction, we have access to a transaction receipt which gives us details about the transaction itself. If you run the above code example with a development blockchain, you will see a basic transaction receipt like this:.
Our round trip has been completed. You can see this strategy in use in this 2 hour tutorial above where I teach you how to build your first decentralized application on the Ethereum blockchain step-by-step. Happy with this tutorial? Then you NEED to join my free training here where I'll show you how to build a real world blockchain app so that you can become a highly paid blockchain developer!

Data structure is also one of the must-have technical skill for a blockchain developer. You, as a developer, need to learn data structures. It will give you the ability to play with the blockchain and configure it according to your requirement. Smart contracts are at the core of modern blockchain networks. Ethereum, for example, offers smart contracts.
It lets you set up business logic or automate certain aspects of dApp. You may want to learn Solidity as it is one of the programming languages used to develop smart contracts. Cryptography is yet another technical skill to have. Blockchain protects the data by using highly effective cryptography algorithms.
Knowing cryptography can help you implement dApps and other blockchain-related services more confidently. With a clear understanding of what is blockchain developer, its role types, responsibilities, and technical skill-set, it is now time we go through the steps to become a blockchain developer.
Like every other technology out there, you need to start from the basics. This includes blockchain basics concepts, ideas, and architecture. Learn about what is decentralization, its public and private approach, the use of consensus in achieving decision making in the network, and so on.
Also, go through blockchain glossary, and you will be able to understand most of the essential concepts. You should also keep a tab on the principles of blockchain. The basics also include getting familiar with popular blockchain development tools. Apart from the technical aspects, you should also get yourself familiar with the market.
Learn about ICOs and cryptocurrencies. Apart from that, also dive deep into cryptography and make sure that you understand all the major cryptographic algorithm used by popular blockchain solutions. Blockchain has grown a lot in the past few years, so its ecosystem. Learn about the following, and you are good to go!
Incredible, if you think you understood step 1, now it is time to move a little deeper. With basics complete, now you need to get familiar with real-world implementation. It is easy to find learners or developers who call themselves blockchain developers, but have not developed anything in reality. To get started, you need to start with an exchange of your choice.
By working through basic cryptocurrency, you will be able to appreciate what blockchain has to offer. Remember, cryptocurrency is just one use-case of blockchain. It is the first use-case of blockchain. Even though we do not recommend investing or trading, you should try out buying some cryptocurrency and storing them in an offline wallet. By going through the whole process, you can understand how cryptocurrency, one of the most significant use-cases of blockchain works.
To store the coins, you need to create wallets. They are digital and can be created easily. But, do ensure that you know about private keys and its safety. With a strong fundamental and practical understanding of cryptocurrency, it is now time to dive deep into coding. For beginners, we recommend learning Solidity. It will help you create and developer dApps and smart contracts on Ethereum blockchain.
You may also want to dive deep into the open-source code of different blockchain platforms. Most of the blockchain platforms or solutions are open source, and hence the code is readily available for scrutiny or learning. However, creating or maintaining an open-source blockchain is not easy.
It requires you to overcome challenges such as security, performance, resource management, and isolation. If you do everything correct, you will have a basic working blockchain! Smart contract is also one of the vital blockchain concepts that you need to learn. It is a computer protocol similar to legal contract in real life. In the words of Emin Gun Sirer — prices are the least interesting part of cryptocurrencies. These are massively important technologies, and they are going to irrevocably change the world.
But I can tell you five reasons that convinced me to take the leap:. Bitcoin was invented 10 years ago, but the rate of innovation has only reached a fever pitch in the last couple of years, especially with the launch of Ethereum in Most of the new companies and ideas in this space have been built on top of Ethereum, which is still very immature. Even if you start now, you can realistically become a world-class expert within a few years. Starting now would be analogous to deep learning experts who began studying the topic in the late s.
Most of the best and brightest students at universities are focusing on machine learning, web programming, or game development. Early on, blockchain was exclusively the realm of cypherpunks, paranoids, and weirdos. Satoshi Nakamoto was not an academic as far as we know. Most of the innovation here has been led by aficionados, entrepreneurs, and independent researchers.
Almost everything you need to know is in white papers, blog posts, public Slack channels, and open-source software. All it takes is rolling up your sleeves and jumping into the fray. Everyone is competing to hire blockchain talent, and projects are feeling the talent crunch. Where else can you build sci-fi stuff like cryptographically secured, decentralized money?
The space could use more transparency, and regulation will eventually come. But without a doubt, cryptocurrencies are one of the most innovative areas you can be working in right now.
So build something no one else knows how to build. If you succeed in building the future of decentralized technology, the world will reward you handsomely. Blockchains are built atop decades of research in computer science, cryptography, and economics. Satoshi Nakamoto was a renegade, but he also knew well the history that preceded him. It helps to have built them from scratch to better understand how they work and their properties.
Cryptography is the namesake and bedrock of cryptocurrencies. The other important cryptographic primitive is the cryptographic hash function. These can be used to construct commitment schemes , and are the building block for Merkle trees. Merkle trees enable Merkle proofs , one of the key optimizations that blockchains use for scalability. Distributed systems are absolutely essential to reasoning about blockchains, so you must build a foundation here before tackling blockchain programming.
Know the difficulties of reasoning about time in a distributed system. Appreciate the tradeoffs between safety and liveness. PBFT is the basis for many non-proof-of-work blockchain consensus algorithms. Learn about sharding such as via consistent hashing , leader-follower replication , and quorum-based commits. The decentralization of blockchains derives in large part from their peer-to-peer network topology.
As such, blockchains are direct descendants of the past P2P networks. To understand the blockchain communication model, you need to understand the basics of computer networking : this means understanding TCP vs UDP , the packet model, what IP packets look like , and roughly how Internet routing works.
Public blockchains tend to spread messages via gossip protocols using flooding. Blockchains have their own place, but they draw upon the lessons of these networks and how they were designed.
Cryptocurrencies are inherently multidisciplinary — this is part of what makes them so fascinating and radical. Besides computer science, cryptography, and networking, they are also deeply interwoven with economics. Cryptocurrencies can derive many security properties through their economic structures, which is often termed cryptoeconomics. As such, economics is essential to understanding cryptocurrencies.
The most important branch of economics that plays into cryptocurrencies is game theory , the study of payoffs and incentives among multiple agents. Two key concepts in your repertoire should be Nash equilibria and Schelling points , as they feature prominently in cryptoeconomic analysis. Cryptocurrencies are not just protocols, they are also forms of money. As such, they respond to the laws of macroeconomics if they can be called laws.
Cryptocurrencies are subject to different monetary policies , and respond predictably to inflation and deflation. You should understand these processes and the effects they have on spending, saving, etc. Another valuable economic concept is the velocity of money , especially as it corresponds to valuing a currency.
Cryptocurrencies are also deeply interwoven with markets, which requires an understanding of microeconomics. For many coin distributions and cryptoeconomic systems, auction theory features prominently. If you are, feel free to skim or skip over them entirely. In October of , Satoshi Nakamoto published a white paper in which he described a protocol for a decentralized digital currency.
He called this protocol Bitcoin. First, I recommend building your intuitions about proof-of-work and the fork choice rule also known as Nakamoto consensus. Start here:. Here are some good resources. Source and slides here. There are also other blockchain implementations you can find, written in various programming languages.
You should also by now have enough background that you should be able to read and understand the original Bitcoin whitepaper. To understand the economics and mechanics of Bitcoin mining, I recommend watching the lecture on Bitcoin mining in the Bitcoin and Cryptocurrencies Princeton course. You should also be able to play around with a Bitcoin block explorer and navigate raw Bitcoin transactions. Now is a good time to study up on the history of Bitcoin and cryptocurrencies.

Content Creators Cryptocurrency. So, how do you become a blockchain developer? How to become a blockchain developer Without any doubt, we are currently in an industrial transformation. New patterns are discovered and popularized. New bugs are found and excised. What was true today might not be true tomorrow. But even so, if you learn Solidity 0.
The basic package of creating a dApp involves being able to write contracts, and then something that can communicate with them. I'm going to assume that the something that communicates with the contracts, be it a frontend, API, or whatever, is written in JavaScript. There are tons of libraries out there, I think most fairly mainstream languages have libraries for communicating with Ethereum, but I know the most about JS's ecosystem.
It's worth mentioning that you can make a dApp without coding a single contract. You can build on other people's contracts - that's part of what being a public blockchain is. Do you want to build an alternative frontend for Uniswap? Uniswap can't stop you. They may have some trademarks, so no, you can't make a frontend for Uniswap and then say you are legit the Uniswap team, but you can say 'hey!
Still, building for Ethereum usually assumes at least general knowledge of smart contract development. It'll be hard to make an interface with the Uniswap contracts if you don't understand what you're looking at when you look at their contracts. Solidity is the language to start with in terms of smart contracts. Vyper is a super cool language, I even have a PR in it largely meaningless, I'm the one who implemented the decision to move to f-strings wherever possible in their codebase, if you know Python , but it's not where you start.
There's a larger community around Solidity, meaning more resources, and more people to reach out to when you're stuck. Cryptozombies is still probably the best tool for diving into Solidity, even though I don't think it's actively maintained.
It's a tutorial where you make a Cryptokitties-like game. For the record, there is a game-building tutorial which is a bit of a work in progress for Vyper here. I actually find Solidity's documentation to be quite readable, even though I usually have a mental block around documentation. Looking at you, Python. I especially find the "Solidity by Example" section to be useful in seeing what different elements of Solidity look like when implemented.
I think the Vim package got a new maintainer, which it desperately needed, and I don't know anything about Emacs support, but I'm sure there's at least something for it. One last point: there are a lot of general purpose contracts that you should never write yourself, except for educational purposes. You should be taken an audited, reliable, open-source boilerplate and building on it, not building it from the ground up. The gold standard is Open Zeppelin. The repository for their contracts are here , and they have their own npm package.
The next thing to discuss after Solidity itself is sandboxes for playing around with contracts. Let's say you've written a contract, and you want to test it out, see if it works. How do you do that? You're right if you think that you aren't supposed to deploy every Hello World and draft contract to mainnet.
Even though there are testnets maintained Ethereum blockchain where the social contract is that the native ETH is worthless, and is not transferable to other chains , the general workflow doesn't go straight to testnets either.
Instead, there are dev chains, virtual chains you can spin up on your machine as needed. That helps you see if your contract is compiling, and lets you test the contract's functions and variables to see if they work as intended.
There are limitations to dev chains - one easy example is that if you're building something that interacts with DAI, it'll mean deploying a clone of Maker DAI to your dev chain every time you spin it up, in addition to deploying your own contracts.
It is still a great first step. Just to clarify, a traditional deployment contains the following steps. First, the contracts need to be compiled. These are used in development quite a bit. Then there is the actual deployment, sending the bytecode of a contract to the chain in a transaction. In order to interact with a contract, you need to know its location on a chain the contract address , and you need its ABI. Etherscan is a valuable tool for getting information on contracts on-chain.
For example, if you know a contract address, but don't know it's ABI, oftentimes Etherscan will have it, or be able to figure it out decompile the bytecode. Once you've deployed, how is your contract going to be interacted with? There may be some cases where just having a contract on-chain is enough, and anyone interacting can be expected to use something like Remix in order to interact with it, but usually not.
I'm going to start with assuming that there is some kind of GUI in your project. If this is the case, you're going to want a framework. A blockchain framework will integrate your contracts into a frontend project, compiling your contracts into JSONs that can be understood by the frontend with proper tools, more on that later , providing the ability to spin up dev chains, and to deploy contracts.
The most popular framework is Truffle. Many of the online resources that teach dApp development teach Truffle, too. Truffle can compile, exposes dev chain tools in the form of Ganache, and more. That being said, I recommend Hardhat. Similar to Truffle I believe it's actually built out of Truffle , you can compile contracts, and get access to dev chains. There's more, though. Solidity does not have console. Hardhat also has fewer compilation issues in my personal experience. Looking at you, node-gyp.
There are also more amenities. Before you go and try and set up your own Hardhat environment, let's talk about web3 libraries, and then I'll have a suggestion which should make that far easier.
Where's the JavaScript code for instantiating a Contract object, and then for calling a function on that contract? Actually, what functions do you use to connect to the chain at all? Obviously, JS doesn't have that built-in. This is where web3 libraries come in. The two most prominent libraries in JavaScript are Web3. I personally find the latter much easier to work with, and would recommend you do the same.
One pro tip is that the current Ethers v5 has docs that are still a work in progress. If you have trouble finding or understanding something in the v5 docs, search the v4 docs as well.

You should also be able to play around with a Bitcoin block explorer and navigate raw Bitcoin transactions.
Now is a good time to study up on the history of Bitcoin and cryptocurrencies. The below video, offered by a UC Berkeley Decal, gives a good overview.
You understand how blockchains and proof-of-work can achieve distributed, Byzantine fault-tolerant consensus within a peer-to-peer network. But a payments network is just one application you can run atop such a blockchain. In , Vitalik Buterin, the creator of Ethereum asked: what if you used a blockchain to implement a decentralized computer? In Ethereum, you pay miners to execute your programs on this distributed virtual machine. This means you can perform arbitrary computations, using a Turing-complete programming language unlike Bitcoin script.
This brings us to smart contracts — the name for programs that run on such a virtual machine. In other words, you can create financial contracts that automatically enforce themselves. Ethereum has enabled the wave of ICOs and developers building atop the blockchain. It is the second largest cryptocurrency behind Bitcoin, it has more than 10x the developers of the next most popular platform, it has the strongest developer team, the most mature tooling, and the majority of ICOs and projects atop it.
It also has the most industry support , which goes a long way. The ideas behind Ethereum have also spawned a wave of innovation in cryptoeconomics. You should dip your toes into the ideas around DAOs , and all of the sci-fi fever dreams that they hint at. As with any technology, the best way to get acquainted with Ethereum is by building a few small projects. The dominant programming language for Ethereum is Solidity, which is a statically typed JavaScript-esque language.
To get your first exposure to Solidity development, I recommend working through all of the CryptoZombies tutorial. I recommend this guide as a first tutorial to walk you through the process. This tutorial does a good job of walking you through an end-to-end blockchain stack and explaining the pieces as they go along.
Karl Floersch has a great tutorial where he walks through how to build a secure commit-reveal voting system. Great, now for your mid-term exam: build a secure coin toss game, where two players can securely bet on the coin flip.
No tutorial this time, do it on your own. Think about possible attacks — how can the players cheat? Can you ensure that they play honestly? Here are some hints. Security is absolutely essential to blockchain development. Smart contracts have been plagued by disastrous hacks, including the DAO hack , the Parity Wallet hack , and the affectionately named Parity Wallet hack 2 now with its own T-shirt.
The truth is, smart contracts are extremely hard to get right. Though the programming toolchain will improve to make these exact attacks harder, they were ultimately all due to programmer error.
There are also many subtler bugs that arise from smart contract programming, such as in frontrunning or secure generation of randomness. As a smart contract developer, you must treat security as paramount. That means any code that handles significant flows of money should be run through static analyzers like Oyente or Securify , tested thoroughly, and then audited by an experienced smart contract auditor. To strengthen your security chops, I recommend working through The Ethernaut by OpenZeppelin, a game where you find and attack vulnerabilities in smart contracts.
Many of them have you replicate real attacks against smart contracts that have occurred in the wild. Phil Daian also has an excellent set of smart contract hacking challenges called Hack This Contract. Expect to revisit this document many times over in your smart contract programming career. The bibliography is also worth exploring for further reading by security experts. Most developers recommend VSCode or Atom for your text editor, since they have decent Solidity plugins. Now is a good time to look into IPFS , which you can use as a fully decentralized filestore at much cheaper cost than the Ethereum blockchain.
Once you have your full Web3 stack set up, try deploying an end-to-end Dapp decentralized application. This tutorial provides a nice full-stack overview using Node and Postgres for the backend, and this tutorial will show you how to create a fully decentralized application, using IPFS as your persistence layer.
7 Skills Needed to Become a Blockchain Developer - Blockchain Developer Career Path
There are lots of different kinds of variables but here are some of the most common:. Cryptocurrencies are also deeply blockchain with markets, which requires learn understanding of microeconomics. To learn this, users first have to build a zombie factory. How to become a blockchain developer With a clear understanding of what is blockchain developer, its role types, responsibilities, and technical development, it is reddit time we go through the steps to become a blockchain developer. Vyper is a super cool language, I even have a PR in it largely meaningless, I'm the one who implemented the decision reddit move to f-strings wherever possible in their codebase, if you know Pythonbut it's not development you start. The gold standard blockchain Open Zeppelin.
