    How to Become a Blockchain Developer: a Thorough Guide

    Once the beta version is ready, the application gets prepared for Release Candidate version. A release candidate is an advanced beta version which is now ready to be a final product. When the application is tested thoroughly, it is moved to the production phase to get ready to be delivered.

    Deployment is the process of putting an application onto a prepared application server. Before an app goes live, it should be deployed on the test network to test its functionalities.

    While deploying an application, administrators can also control which versions of the app should be deployed to different resources using provisioning. After provisioning an application, it should be hosted on the main chain. For example, if you have built an application on the public blockchain, it should be released on the main network. If your application has both off-chain and on-chain business entities, i. The application should have the potential to upgrade according to the new business requirements and prioritization.

    For example, if you have to upgrade the smart contract, later on, you should be able to deploy the new contracts seamlessly. Design and develop the application in a way that adding or upgrading components does not affect the existing application. From identifying the goals to gathering the requirements, choosing the right blockchain platform, preparing designs for the software, building and deploying the application, this article would help you to understand the step-by-step blockchain development process.

What is Blockchain? The technology comes with the following benefits: Decentralization: to remove the single points of failure from the system. Transparency: by making it possible for every member of the network to access the data at the same time.

    Trust: through mass consensus. Security: through immutable records of transactions. Let us decode what all is needed to build a scalable and secure blockchain based application. Here is a step by step guide to the blockchain development process for building a blockchain based solution.

    Akash Takyar. Akash is an early adopter of new technology, a passionate technology enthusiast, and an investor in AI and IoT startups. Write to Akash. Here are some of the blockchain platforms you can choose on the basis of their functionality and mechanism: Ethereum:- Designed as a general programming platform, Ethereum is an open-source and public blockchain based distributed computing platform, featuring the functionality of smart contracts.

    Hyperledger Fabric:- Hyperledger Fabric is open-source blockchain platform suitable for building the enterprise applications.

    The first language which fully supports chaincode is Golang. Hyperledger Sawtooth:- Similar to Hyperledger Fabric, Hyperledger Sawtooth is also designed for building applications on permissioned blockchain networks.

    The first participant who completes the waiting time becomes the leader of the new block. Secondly, did the winner actually complete the specified amount of waiting time. Blockchain Ideation. Prototype After completing the theoretical build-up and receiving feedback from every involved stakeholder, you should come up with a prototype containing sketches, information architecture, mockups, designs, and tested product.

    Here are some of the common reasons for which an API is required: Performing auditing functions. Storing and retrieval of data. Generating pairs of keys and mapping them to the specific addresses. Performing data authentication with the help of hashes and digital signatures. Managing and triggering of smart contracts to run the business capabilities of an application.

    Development required. With privacy channels provision provided by different blockchain platforms, you can permit which user can blockchain confidential data. Ethereum Virtual Machine 4. Cryptocurrencies are still in their infancy, and I really believe the is the most rapidly evolving space you how be working in. There get other involved popular blockchains, and some companies create their own proprietary blockchains.

    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. 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.

    First, start building your own projects. OpenZeppelin might be a good place to start for smart contracts. Get on their Slack or Rocketchat — the devs are usually readily accessible. Beyond open source contributions, there are also many blockchain hackathons constantly popping up. Wherever it is, find your people and continue learning. The best way to really understand the blockchain world is to immerse yourself in it. The three fantastic podcasts I recommend are the Software Engineering Daily Blockchain interviews , which provide good technical intros to many topics and cryptocurrencies.
