    Blockchain code development

    Warning to the newbies, though: As a type-only language with fairly outdated syntax, the learning curve is a bit steep. However, as most blockchain technologies are written in this language, any efforts you put in to learn this language will pay forth abundantly. Better memory control. There are a lot of demands in the blockchain ecosystem. For instance, the platform needs to be a secure fortress but at the same time execute transactions and interact with all the nodes at a faster speed.

    For all these to happen, you need to have better control over memory and CPU usage. Superb multithreading. Threads are a bundle of instructions that are to be executed at the same time. During blockchain development, you will come across tasks that parallelize and those that do not.

    Most languages can only handle one of these tasks and not both. Compile time polymorphism. It also happens that polymorphism using a certain feature in several ways is a property of OOP. Code isolation. This archaic but revolutionary coding language has namespace features that can be shipped from one place to another. But at times, collisions can occur and distort the entire system.

    Besides that, the language sports practical features like debuggers and special analytical tools that can detect or optimize various functions. It was developed in by a Dutch programmer by the name of Guido van Rossum. The simple nature of this language has seen it be supported by a massive crowd of both new and established developers. Simplicity can be easily translated to mean inefficiency. However, Python is good enough to build complex digital ledgers that are stable and reliable.

    And here is the best part: This language is scripted and can be compiled and uncompiled. For instance, when you find a bug in your code, you just fix it and reload your application. Additionally, the language offers developers a vast, free resource center that they can use to write their blockchain code. JavaScript is one of the most-used languages on the World Wide Web. If you want an interactive site with beautiful UIs, this is the language to use.

    All the major browsers such as Google Chrome and Firefox support it. We already said that a blockchain is, roughly put, a system of blocks placed one after the other. JavaScript is one of the go-to languages when making a simple but tamperproof blockchain that is impossible for hackers and other deceitful individuals to alter. Just one setback, though: The language lacks the SHA hash function.

    The language is not only beginner-friendly but also offers tips and instructions on how to go about using its code. While the language is not very complicated, those who have a fair grasp of modern programming languages have an advantage. Even though Solidity is still trying to establish its footing in the coding world, Ethereum the second-biggest cryptocurrency after bitcoin is already using it.

    Well, they made the language, so it makes sense that they be the first ones to use it. Nevertheless, Ethereum blockchain is one of the most efficient when it comes to speed and ease of creating smart contracts.

    So if you are looking to create a decentralized app, hold an initial coin offering, or build a secure, immutable, and multipurpose blockchain, Solidity is the language to use.

    It's a must-know language for anyone who wishes to integrate smart contracts in their digital ledger. GO is the short form of GOLang, a relatively modern coding language that was developed in at Google and officially released for public use in GO inherently runs in an operating system, and this means maximum flexibility, especially when dealing with several parts of a blockchain simultaneously. Although blockchain represents only a single item, there are different parts in it that developers can work on.

    The core parts of a blockchain you can develop include:. The most skilled programmers usually browse through a storm of resources on anything before getting started.

    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. Another interesting up-and-coming technical podcast is Conspiratus. Subscribe to the Ethereum Foundation and watch Devcon3 presentations. Blockchain at Berkeley records many of their lectures, most of which are excellent technical overviews. Decypher Media also posts talks, whitepaper reviews, and tutorials.

    Jackson Palmer has engaging weekly overviews, these are on the less technical side but very evenly presented. For realtime blockchain chatter, it lives mostly in two places: Reddit, and Twitter. For Reddit, most subreddits are very low quality and dominated by noise.

    Most subreddits though are primarily dominated by speculators, and are not a good use of your attention. Stay away from Bitcoin-related subreddits. Bitcoin notoriously has one of the most toxic communities, and Reddit only magnifies that. Twitter is more of a mixed bag. For better or for worse, most blockchain people live on Twitter. Blockchain Twitter was somewhat of a mystery to me at first, but eventually I developed an informal ontology of Twitter blockchain people.

    Entrepreneurs can be okay, though they mostly act as hype men or tweet about their own projects. Pay the most attention to the builders. A few representatives from each category do a breadth-first search of who these people follow if you want to fill out your Twitter feed :.

    All that said, I recommend minimizing your exposure to Twitter and Reddit. Important information will bubble up to you asynchronously. I recommend subscribing to Inside Bitcoin for daily digests of the most important crypto news pieces it covers more than just Bitcoin.

    For token projects, Token Economy has excellent weekly writeups, and Week in Ethereum has good digests of developer-focused happenings in the Ethereum ecosystem. Focus on building stuff and learning. Long-form content tends to be the best bang for the buck.

    I recommend following these:. If you want a more structured approach to learning this material, there are a few high-quality books and courses out there and a lot of low-quality ones. The best overall textbook for blockchains is Bitcoin and Cryptocurrency Technologies which accompanies the Princeton Coursera course. If you want a more structured approach to learning this material, there are a few high-quality courses out there and a lot of low-quality ones. As I said before, blockchain startups are hiring like crazy.

    AngelList did a great writeup on how to get a job in the crypto space. The job aggregators are more global though. Most blockchain teams are willing to hire remote for the right talent. Many devs are readily accessible on Twitter, Github, or on their public Slack channels.

    If you have a solid portfolio and can demonstrate technical chops, most people will be impressed if you show some initiative. Cryptocurrencies are still in their infancy, and I really believe the is the most rapidly evolving space you can be working in.

    If this article was helpful, tweet it. Learn to code for free. Get started. Forum Donate. This guide will proceed in ten parts: Why should you learn blockchain development? Prerequisites The theoretical foundations of Bitcoin Building a blockchain yourself Ethereum and smart contract programming Smart contract security Taking off the training wheels Building your own projects Navigating the blockchain community Getting a job Why should you learn blockchain development?

    Much of the innovation is happening outside of academia. The demand for talent far, far exceeds supply. Cryptocurrencies are just really damn cool. So say you want to throw in your hat. What do you need to know before you get into the ring? Here are some good prerequisites to be familiar with, in order of importance. Cryptography Cryptography is the namesake and bedrock of cryptocurrencies.

    Networking The decentralization of blockchains derives in large part from their peer-to-peer network topology. Economics Cryptocurrencies are inherently multidisciplinary — this is part of what makes them so fascinating and radical. Game theory The most important branch of economics that plays into cryptocurrencies is game theory , the study of payoffs and incentives among multiple agents. Macroeconomics Cryptocurrencies are not just protocols, they are also forms of money.

    Microeconomics Cryptocurrencies are also deeply interwoven with markets, which requires an understanding of microeconomics. The Theoretical Foundations of Bitcoin In October of , Satoshi Nakamoto published a white paper in which he described a protocol for a decentralized digital currency.

    Start here: I recommend watching more than one video explanation to get the idea seared into your head: Great. You should have an idea of why Bitcoin folks argue so much about the block size. Segregated witness, a. SegWit , not essential but it comes up a lot.


    Public blockchains blockchain to spread messages via gossip protocols using flooding. If you have an application that development to manage massive data, code can be used to manage a single shared blockchain ledger. Code a name for your contract. The demand for talent far, far exceeds supply. Mist Before using Ethereum, you should have a place development store Ether tokens and execute smart contracts.

    Building a Blockchain in Under 15 Minutes - Programmer explains

    A consensus in the network validates the ledger, which implies that everyone must agree on it. Changing a single record would result in the modification of all subsequent records. Thus, the data saved on the blockchain is:. If your company manages products which are traded via a complicated supply chain, you would understand how difficult it can be to track an item from its origin.

    When the supply of goods from one place to another is recorded on the blockchain, you get a complete audit trail representing where an asset came from and tracks each stop that it covers on the journey. Previous records saved on the blockchain can help to verify the authenticity of products and protect from frauds. You can execute transactions fastly and securely by automating and simplifying business processes with blockchain.

    Everyone within the network can access the same information at all times, which results in a quick settlement. Reducing costs is a priority for most businesses. While learning about how blockchain can add value to your business, it is also essential to know about when you should use it. Following are some of the questions that will help you determine if integrating blockchain into your existing solution is a good idea:.

    Therefore, blockchain is of no use in that case. If you have an application that needs to manage massive data, blockchain can be used to manage a single shared distributed ledger. Instead of maintaining multiple databases, blockchain technology will allow you to have a single transparent view of the updated ledger, shared with all network nodes. Though paper-based documents are difficult to counterfeit, they have limited permanence.

    If transactions need to be updated and shared frequently, maintaining them on papers can be a time-consuming process. If the data and its history are crucial for your business, you might require a blockchain solution that allows multiple parties to write entries into an incorruptible system.

    Does your database need high-performance millisecond transactions? If yes, you should stick to the centralized system for managing the records.

    On the other hand, even though blockchain databases are slow, they are far more secure than the centralized system. There could be many reasons why a third party should handle some authorizations and authentications, as it can sometimes be desirable. But, third-party authorities can always create trust issues due to a lack of transparency.

    On the other hand, multiple parties manage blockchain data, and information is validated via an agreed-upon consensus algorithm.

    If you have privacy concerns, it can become possible to provide read-only and write-only permissions to a specific party using blockchain. No dependency on a central authority will reduce:. Trusting other parties is essential when doing business, especially in a partnership situation. We have to trust banks to keep our money secure and business associates to maintain agreements. What if the trust gets broken? Now, the question is, how would you know when to use blockchain.

    Though blockchain is a trustless environment, parties can work simultaneously without worrying as they have an updated ledger at all times. It uses various consensus algorithms to validate all transactions without giving more attention to any particular party.

    Hence, it brings fairness to the system. Everyone considers blockchain as an immutable system as it does not allow you to change rules on the system once they are written.

    When estimating the cost to build a blockchain-based platform or application, you need to consider the following scenarios:. Here is our analysis of the estimated cost of blockchain development for a minimum viable product when using different development resources.

    Working with an in-house team of developers is quite expensive, but it can provide you more control over blockchain development. However, you should take this path if software development is your core business. On the other hand, hiring freelance blockchain developers could be less expensive but very risky. Working with a third-party company could be a viable option if your project is enormous.

    Blockchain companies are experienced and can help you at every step of the development process. When compared to an in-house development team, the cost of blockchain companies is lower. Every business requires a digital solution to run their business operations efficiently. Building a blockchain app can build trust and offer transparency while removing additional intermediaries. Before implementing blockchain technology and estimating its cost, it is essential to understand the type of blockchain app you need.

    Whether you need a permissioned blockchain app or a permissionless blockchain app, you need to consider which application can suit your business needs. Also, the cost of a blockchain application varies from industry to industry. For example, you may need an app for supply chain management, healthcare, real estate, education, and many other business domains. The cost of an app will depend on the complexity of the project.

    The cost of blockchain app development also depends on the number of resources required to develop an application. Salaries of blockchain experts are the significant expenses you should not miss when calculating the cost to build an app. While investing in blockchain developers, ensure you have hired the best ones and added their salaries to the total expense. Companies might use agile methodology tools such as Jira, Confluence, and Trello to manage blockchain projects.

    They use such tools to test an app, track timelines, and deliverables. Therefore, the price of project management tools is also added to the cost of blockchain implementation. Your blockchain app might require a subscription to third-party subscription tools such as bug tracking tools, notification services, amazon web services, software monitoring services, and data analytics tools.

    The cost of subscription tools also contributes to the cost of blockchain app development. In this section, we have explained the process of building a blockchain-based application. First of all, it is essential to develop a problem statement and understand all of the issues you want to solve with a proposed solution.

    Ensure that the blockchain solution will benefit your business abilities. Analyze whether you need to migrate your current solution to the blockchain, or you require a new application to be developed from scratch. For example, suppose you are a healthcare provider who wants to develop a blockchain-based health record exchange app. In that case, you should know various use cases of the applications and what benefits it will offer to users.

    Once you decide that you need a blockchain solution for your business operations, the next step is to select the right blockchain platform and blockchain development tools for your project.

    As mentioned above in the article, building a blockchain from scratch requires thorough research and takes months to years to develop it successfully. Therefore, you should build a blockchain app on top of a blockchain platform that meets your business requirements.

    You should identify the right blockchain platform for your application based on the factors like consensus mechanism and problems you want to solve. For example, you can build an Ethereum-based application to develop a decentralized public application with smart contracts. When the blockchain platform is identified, you must do brainstorming and understand the exact business needs. Once you identify the blockchain platform for developing a blockchain application, you should focus on drafting business requirements and brainstorming ideas.

    Find what technology components should be added as off-chain or on-chain entities on the blockchain ecosystem. Create a roadmap of the product that will help you to build an application within a decided deadline. You should come up with a blockchain model and conceptual workflow of the blockchain application.

    Also, decide if the application needs to be developed on a permissioned or permissionless blockchain network. It would help if you also decided on front-end programming languages to be used, servers, and external databases in this stage. A proof of concept is done to represent the practical applicability of a blockchain project. It can be either a design prototype or a theoretical build-up. In Theoretical Build-up, each project requires theoretical cases so that users could understand the applicability and viability of the product.

    After creating theoretical build-up and receiving feedback, a prototype is designed, which includes:. When the client approves the PoC, the next step is to prepare technical and visual designs for the application. Since you have planned an entire application at this stage, start creating UIs for each software component.

    Designs APIs that will be integrated with user interfaces to run an application at the back-end. Once the admin consoles and user interfaces are designed, the application gets ready for development.

    Development is the significant phase of the blockchain development process, where you should be ready to build the blockchain app. In this specific stage, you either have to develop or integrate APIs for particular use cases of the application. The application is built under multiple versions. Once the client approves it, the application moves to the next stage, i. But, the software might not comprise all the features at this stage.

    After the alpha version is released, the app is prepared for the beta version. During Beta Phase, the software application has the complete feature set but with some unknown bugs. Developers share the beta version with a particular group of people outside the organization to test its functionality. Once the beta version is approved and tested, the application moves to the Release Candidate version, which is an advanced beta version that is ready to be a final application and can be launched.

    After thorough testing, the application moves to the production phase and gets ready for delivery. Before an app goes live, you should deploy it on the test network to carefully test its functionalities.

    When deploying an application, administrators can also manage which versions of the app need to be deployed to various resources with provisioning. Once an application is provisioned, it needs to be hosted on the main chain. If your blockchain app is a hybrid solution, i. The application should be able to upgrade according to any new business needs and prioritization.

    For instance, if you need to upgrade the smart contract, later on, you should be able to deploy the new contracts without any difficulty. Developing and deploying an app does not mean you are done. Instead, a software application needs to be maintained post-development to ensure that it works with all types of upgrades in the future. An Ethereum client, Geth, is used to run Ethereum nodes in the Go programming language. Using Geth, users can mine Ethers, create smart contracts and run them on EVM, explore the block history and send tokens between addresses.

    Geth can be downloaded and installed on Linux, Windows and Mac. It supports two types of installations, Scripted and Binary. Once you start using the Geth, you either have an option to create your own blockchain based on the provided settings or connect to the existing blockchain. Remix IDE is a compiler used for small contracts. It is a browser-based tool used to create and deploy smart contracts. You can use Remix IDE to write, debug, test and deploy smart contracts using the Solidity programming language.

    Remix can connect to the Ethereum blockchain via Metamask. Before using Ethereum, you should have a place to store Ether tokens and execute smart contracts. Mist is the Ethereum wallet used for smart contract deployment and is available for Mac, Windows and Linux. While installing Mist, remember once you set up the password, you cannot update it again.

    Create a strong password and never forget it. It allows users to make calls to the blockchain without the need to run an Ethereum node. GanacheCLI is used for the instant mining of transactions. It is an easy-to-use API that provides you with an overview of test chain events.

    Security plays a prominent role when it comes to building a blockchain application. You need to ensure that the Solidity code does not have security holes. Solium tool is specifically designed to format solidity code and fix security issues in the code.

    EtherScripter has an easy-to-use interface used for coding basic smart contracts. For those that aren't familiar with Infura, it provides the tools and infrastructure that allow developers to easily take their blockchain application from testing to scaled deployment - with simple, reliable access to Ethereum mainnet and testnets, and also has support for IPFS.

    Details can be found on the Getting started with Infura blog and on the Infura Docs pages. To use Infura, the first step is to either create or connect to an existing Infura project. The IDE will step through this process. At this point the extension will prompt you for credentials to sign into Infura. Simply click the sign in button. Don't worry if you don't already have an Infura account, because you can create one if needed.

    On the Infura login page, login with your Infura account credentials. If you don't already have an Infura account, simply click the Sign Up link at the bottom. After signing into Infura, you will be askted for authorization to share your Infura projects with the extension. Click Authorize. Next close the browser window and you will back in the IDE. A prompt will be presented to allow you to enter a project name.

    Enter the desired name for this. Next select the availability of the project inside Infura public or private. By default, public is the option used. After a few seconds, the Blockchain view will show a new Infura Service, with your project nested under, and under this will the various endpoints that Infura provides. Now that a connection to Infura has been created, this network can easily be targeted when deploying contracts. When right clicking and deploying contracts, a set of options will be added for these new Infura destinations.

    Simply select the desired target network endpoint and the extension will deploy the contracts to this location. Hyperledger Besu is a popular Ethereum client that is unique in that it offers a client that can be used in either public networks, such as Ethereum mainnet or private, consortium based networks.

    It can be deployed a variety of ways , and recently a preview has been made available in Azure. Currently, the Hyperledger Besu is fully compatible with the extension, however the provisioning of the nodes is not yet fully integrated. To connect to a running Besu node with the extension, you can do the following:. This varies based on the deployment model, for Azure deployments these can be retrieved from the output parameters from the deployment.

    Update the configuration manually. This is shown in the video below. The extension has the ability to use an HD Wallet provider that simply requires a file with a mnemonic to function. If you are a developer that would like to target a network that leverages Azure, this option is also available. The option to create new networks or connect to existing ones are is available, the same as with Infura and Local networks!

    Enter the name of your Consortium. Wait until your resource has been created in Azure. Note: Deploying the Azure Blockchain Service takes quite some time to complete. Please check the deployment status in the Azure portal. Our Wiki page includes a comprehensive getting started guide with detailed usage instructions for this plugin.
