A Complete Guide to Blockchain Development
Network effects also applies to the developer communities that grows around each Blockchain. In order to develop applications in a reasonable time and cost, we need not only a rich and mature ecosystem of developer tools and libraries, but also a vibrant community of competent developers. This can only happen if the community reaches a certain size. If you decide to pick Ethereum, before you rush to learn the tech, the next step would be to get more familiar with what kind of applications developers are building on it.
There are more than applications built on Ethereum and new ones are released every day. We call these applications Decentralized Applications, or Dapps. A great way to discover popular Dapps is to visit a Dapp list website. I personally prefer DappRadar because its easier to access their Dapp lists and also because they have all sort of interesting rankings like the Dapps with the most DAU daily active users or with the most transactions per day.
They are popular for trading lesser-known ERC20 tokens which lack liquidity. Gaming Dapps are mostly what we call collectible games. Users first buy characters from the game creators and then interact with other characters in different ways: fighting, breeding, etc… Compared to non-Blockchain games, the most distinctive feature of Blockchain games is the economy part. Thanks to the Blockchain, players are able to trade their characters freely with other players, without ever worrying about the interference of the game creators.
The most famous gaming Dapp is CryptoKitties , where players collect cats that can breed. Gambling Dapps were among the first kind of Dapps to be built on Ethereum. Fomo3D is one of the most famous, where players have to keep investing ether to avoid letting the last player win all the money. Be aware that gambling Dapps on Ethereum suffer from a bad reputation, because many of them were openly! The last category is marketplaces. There are only a few marketplaces on Ethereum, but one that is making a lot of noise at the moment is the market place of Decentraland , a virtual reality world built on Ethereum.
What are you going to build? A decentralized exchange? Or maybe something completely different? In any case, keep in mind that your Dapp will benefit the most from Ethereum if it has some sort of economy where users trade assets with Ethereum tokens.
Once you have made up your mind about what you want to build, you need to actually start to think of how you will build your Dapp. To build your Dapp, you will need to learn about 3 components:. The rest of this article will introduce you these and give you tips on what are the best resources to learn them.
The Ethereum protocol is at the basis of smart contracts and Dapps. You need to understand the basics of Ethereum to understand the rest of the development process on Ethereum. Start by reading the Ethereum white paper , which is a high-level description of what is Ethereum. It was written by Vitalik Buterin, the creator of Ethereum. This is the technical specification used by developers who implement the Ethereum protocol. A lot of mathematical notations are used, and its not for the faint of heart.
I had to re-read several times to understand it. Another good place to learn about Ethereum is the Ethereum research forum.
In the forum, the research team of the Ethereum foundation and Vitalik Buterin regularly discuss the latest developments in the Ethereum protocol. In your quest of understanding Ethereum, you could also read the source code of several implementations clients. You could read the code of the main clients like Geth Go or Parity Rust but these might not be the most readable. Instead, I would recommend to checkout a Python implementation Trinity or a Javascript. For example, Bitcore is the main client of Bitcoin, and Geth and is the main client of Ethereum.
Now that you know about Ethereum, you are probably curious to know how we build applications on top of it the so-called Dapps. But before being able to learn how to build Dapps, you need to learn about the tools that are required, and about smart contracts.
Solc is the compiler of the Solidity programming language. You can compile it directly from source, or more simply you can use a package in your favorite language. Web3 is a library used to communicate with Ethereum clients like Geth or Parity. Where web3 really shine is in its ability to dynamically create abstractions objects that represent a smart contract.
These smart contract objects simplify a lot the interactions with a smart contract, and you can use them as if Ethereum had implemented an API specifically for each of the functions of your smart contract. To learn about web3, checkout the official documentation , as well as my video tutorials on How to deploy a smart contract with web3 and How to call a smart contract method with web3. By the way, in you are into Python you will be happy to learn that a Python port of web3 also exist.
Oh, and make sure that you when follow a tutorial about web3 you know which version of web3 the tutorial is using: pre 1. Remix is an online IDE for Solidity smart contracts.
Truffle is the most popular framework for developing Ethereum Dapps. It is written in Nodejs and has a strong community behind it. It has recently launched its own online academy and its own conference. Truffle makes deploying smart contracts a breeze. Without Truffle, we would need to combine many different tools. The official Docs are very good, and if you prefer videos you can checkout my Introduction to Truffle.
Ganache is a local Ethereum Blockchain used for development. With Ganache, you just need to run a command to start a local Ethereum node and have 10 addresses pre-funded with Ether fake Ether of course , which is very handy for development. Metamask is an Ethereum wallet that is packaged as a browser extension. It is used by Dapps when requesting a user to sign a transaction. Transactions might send ether from the user address to another address, or simply change the value of a variable in a smart contract.
Metamask is available on Chrome and Firefox but the Chrome extension is more popular. Smart contracts are the main building blocks of Dapps. There are small programs deployed on the Ethereum Blockchain that run autonomously once deployed. It just runs forever, outside the control of anybody. Solidity is the main language that is used for writing smart contracts.
It has a syntax that is similar to Javascript but the similarity is just cosmetic. There is an intermediary compilation step, in which Solidity code is compiled to a bytecode that the Ethereum Virtual Machine the component of Ethereum that runs smart contracts can understand.
Also, contrary to Javascript, Solidity is a typed language, which means that you need to specify the type of each variable. Contrary to Javascript and most languages, Solidity is much more primitive and much more limited. Expect some surprises in your learning process! As a first step into Solidity, a lot of people like to use CryptoZombies. The project will work with the IoT ecosystem, and so is based on PoS and comes with its own consensus algorithm. Hdac recognizes that balancing scalability, security, and decentralization is a current pain point in enterprise blockchain.
The firm will bolster its expansion with the sponsorship of successful esports team G2 and plans to be listed on more global exchanges. Hyundai has previously partnered with IBM for blockchain in supply chain finance. You can find various open-source blockchains available in the market that simplify the development process with forking.
With industrial-grade technology, Bitshares blockchain focuses on businesses, individuals, or organizations with a free-market economy and a robust ecosystem. Some features of Bitshares Blockchain that make it an ideal platform for the development of blockchain solutions are:.
Blocks are confirmed rapidly, and transactions are added to the blockchain within 1. Bitshares ensures the blockchain covers costs to keep going with no maturity date, as it is backed by an ecosystem of dApps to self-fund its native token BTS. It is impossible to hack the Delegated Proof-of-Stake DPoS protocol as it involves taking out many global, active and trusted delegates.
Bitshares allows you to create your own cryptocurrency and blockchain platform, just like EOS, Corda, Stellar, or Tron. You may simply fork any open-source blockchain to build your own blockchain platform for your specific enterprise requirements.
Building a blockchain from scratch takes a considerable amount of time. Innovators are discovering ways to implement blockchain across financial services, supply chain, government, healthcare, retail, and many other industries to transform business models. Blockchain adds value to businesses by offering:.
The history of transactions is becoming more transparent with the implementation of blockchain. Since blockchain is a distributed ledger, all members of the network share the same updated ledger. 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.
Plan can understand that development is very exciting, and its great to make money, but plan you blockchain on this alone your excitement might be short-lived. Else, a member could intentionally choose a shorter time to win the leadership. Click on a thumb to rate it! It development important to note that a whitepaper is specific to a platform or DApp, whereas a business plan covers an entire blockchain and its interests or holdings in their entirety.

The Better Blog
If you are into learning games, you might also enjoy Ethernaut , another game where you have to hack a smart contract. Next, I would recommend to spend some time reading the official Solidity Documentation. It is the most comprehensive resource on the topic and it is regularly updated. On my Youtube channel you can find some other resources for learning Solidity and smart contracts.
The author is quite knowledgable in Solidity and covers some advanced topics. You might also want to learn about how to write safe Ethereum smart contracts. In smart contracts, you manipulate other people money, so you will be the target of hackers. These are good resources for learning about security in Solidity:. If you want to to get more tips about learning Solidity, read my article on what is the best way to learn Solidity. Because smart contracts are not very user-friendly we cannot ask end users to directly interact with them.
Instead, we need to build easy-to-use UI for users. Before reading this article, you might have heard previously of Cryptokitties. Cryptokitties is this game where players buy, breed and trade kitties. This is built on Ethereum and is a good example of Dapp. First, we have the Cryptokitties website. This is the main interface interface for user. The website backend is deployed on private servers, and the frontend is a regular webapp.
Nothing new here. Finally, we have the Cryptokitties smart contract, which is where the game data is stored. For example, if a player buys a kitty, this information will be stored in the Cryptokitties smart contract. The smart contract is deployed on the Ethereum blockchain. These 3 parts interact together to form a Dapp.
In order to build your own Dapp, you need to build these 3 parts and make them communicate which each other. You can start by following my Free tutorial series on how to build a Todo list Dapp on Ethereum.
This is a 8 steps tutorial where we will build a complete Dapp with the smart contract and the frontend, starting from the smart contract, and all the way up to the frontend:.
Plus it will have 2 bonus series on how to integrate React in a Dapp and how to use Drizzle, the frontend framework of Truffle. If you are looking for online courses for learning to build Ethereum Dapp, you can check out the below links:. If you reach this step you would have accomplished a lot in your quest to become a Blockchain developer and find a job at Blockchain company. But before you do that you need to prepare yourself for these interviews.
Employers will ask you to explain how a Blockchain work, and what are the different elements of Blockchain. Since Blockchain was created by Bitcoin, the 2 are often mixed together in Blockchain interviews. You can check out my article on what are the Top 12 questions in Blockchain Interviews.
When I first got into Blockchain, I stumbled upon this book. I read it end-to-end in a couple of days and it made me become passionate about Blockchain. Throughout my journey in Blockchain and Ethereum, it helped me a lot to have read this book. Thanks to it, I acquired a good grasp on the Blockchain technology and Bitcoin. Knowing that most Blockchain systems and somehow based on Bitcoin, it helps a lot to have a good foundation there. You can buy the book from Amazon or read it for free on Github.
The author recently released an updated version, following the latest development of Bitcoin Segwit. Make sure you buy this version. General job boards not specifically focused on Blockchain also usually have a decent numbers of Blockchain jobs:.
More on that in the next section. At some point in your journey of becoming a Blockchain developer, you will certainly need some help. Fortunately you are not alone and there are a lot of online communities where you can ask for some help.
The Ethereum stack exchange is great place to get some answers. Another way to get help is to meet other developers in real-life. A great way to do this is to go to Ethereum meetups and conferences. For meetups, you can go to meetup to find Ethereum and Blockchain meetups in your region. Make sure you pick a meetup that is focused on the tech, as many are focused on the business side of things and tend to try to sell you their latest ICO-investment crap.
As for conferences, the most famous one for Ethereum is DevCon a bit pricy though. These are way cheaper than DevCon and less crowded. Finally, if you want to keep updated with the latest news of the Ethereum ecosystem, you can consult these resources:. I hoped that article helped you to figure out how to become a Blockchain developer. If you want to receive some career advice or have any questions about becoming an Ethereum developer, feel free to reach out at julien [at] eattheblocks [dot] com.
Feel free to explore the other resources on this website to learn more about Dapp development. Excellent article. It is the fastest way to find your new job in Blockchain. Fantastic article, thank you.
Truly useful, I will be using it to guide my blockchain development apprenticeship. Amazing article. I was looking for such an article for the last 2 months which could give me some direction. Would like to connect with you on LinkedIn.
I want to select a blockchain, as you said in Section 2. Thank you for helping me In the meantime, I am currently working for an economic finance magazine on blockchain. Great, i am a blockchain developer, I really accept this plan will work our for new comers in blockchain field! As a Blockchain Expert, i strongly agree all the above steps to initiate for becoming Blockchain Developers. Your email address will not be published. Skip to content Do you want to become a become Blockchain developer?
However, It can also come across as mysterious and hard to figure out for newcomers: Where do I get started to get into Blockchain? What do I need to learn to become a Blockchain developer? Do I need to be a cryptography expert to make it into Blockchain? The blockchain is a chain of time-stamped digital records, known as blocks, which are linked together cryptographically.
Since every record that goes into the blockchain always stays there, it can be traced anytime, and nobody can tamper the blocks of information. To learn more about the blockchain, read this article. Before we go deeper into the blockchain development process, firstly it is essential to define a problem statement. At this step, you should know what all problems a proposed solution is expected to solve.
Make sure investing time and efforts in blockchain would benefit your business capabilities or not. You can also migrate your current application to the blockchain network without building it from scratch. Identify a blockchain use-case for your application and ensure if your idea requires blockchain or not. For example, if you are a food supplier and looking to build a blockchain based supply chain application, you should understand the multiple use-cases of the application and how it is going to benefit your business and the consumer.
Once you have identified that your business requires a blockchain based solution, the next step is to choose the right blockchain platform for your project. You require a blockchain platform to build a decentralized application without having to create a blockchain from scratch. The blockchain platform you need depends on the consensus mechanism and the problems you are going to solve.
Designed as a general programming platform, Ethereum is an open-source and public blockchain based distributed computing platform, featuring the functionality of smart contracts.
Build your application on Ethereum if you want to develop a decentralized public application with smart contracts. Smart contracts in Ethereum are written in Solidity programming language, which is a subset of Javascript.
Use Remix IDE, an open-source tool provided by Ethereum organization to create smart contracts straight from the browser. Hyperledger Fabric is open-source blockchain platform suitable for building the enterprise applications. It supports distributed ledger solutions on permissioned networks where all participants have known and authorized identities. Built on the modular architecture, Hyperledger Fabric has the potential to maximize the flexibility and resilience of blockchain applications.
The pluggable architecture components include encryption or consensus. If you want to build a decentralized solution for your enterprise which should not be available to the public, choose Hyperledger Fabric for your project. Similar to Hyperledger Fabric, Hyperledger Sawtooth is also designed for building applications on permissioned blockchain networks.
This consensus mechanism needs to meet the two requirements to work fairly. Firstly, did the lottery winner choose a wait time randomly?
Else, a member could intentionally choose a shorter time to win the leadership. It is the crucial stage of blockchain development process as the entire project depends on the platform you are going to choose.
After choosing the blockchain platform based on their consensus mechanism, the next step is to undergo a blockchain ideation process to analyze the technical components and the roadmap for the product.
Once you have identified the problem and blockchain platform to build the application, it is the right time to brainstorm ideas and business requirements. In this step of the blockchain development process, you need to evaluate, formulate, and prioritize use cases for blockchain experimentation. Decide what components should be added as on-chain and off-chain business entities.
Prepare a roadmap of the product, i. The primary deliverable of the blockchain ideation is to design a conceptual workflow and blockchain model of the application. Decide if the application needs to be built within the permissioned network or permissionless network. While formulating ideas, you also have to make decisions related to the front-end programming language, external database, and servers for your application.
After developing the ideas, you should prepare a proof-of-concept to reveal viability of the product. A proof-of-concept is a way to demonstrate the practical potential of a blockchain project and it can either be a theoretical build-up or a prototype. Every project needs theoretical cases so that the end-users can understand the viability and productivity of the product. Create proposals to explain the parameters of the project. 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.
This upcoming project will focus on implementing blockchain in the building and maintenance of IoT enabled smart homes. The project will work with the IoT ecosystem, and so is based on PoS and comes with its own consensus algorithm. Hdac recognizes that balancing scalability, security, and decentralization is a current pain point in enterprise blockchain.
The firm will bolster its expansion with the sponsorship of successful esports team G2 and plans to be listed on more global exchanges.

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. With a simple drag and drop interface, developers can connect different components as jigsaw puzzle pieces for developing a contract.
It only supports the Serpent programming language. A development framework for Ethereum-based dApps, Embark, is used to build and deploy dApps and enable you to create smart contracts written in Javascript programming language. If an application contains multiple contracts, Embark can also handle the migration of smart contracts. Developers can manage contracts on multiple blockchains such as live network, testnet and private net using the Embark framework. It is a wallet that connects Chrome or Firefox with Ethereum blockchain by acting as a browser extension.
It can save keys for Ether and ERC20 tokens. It can be installed simply as a Chrome extension. Since blockchain is immutable and transactions once added to it cannot be updated or removed, untested programs can result in high costs.
That is why it is essential to test a decentralized application before it is deployed on the mainnet. Ensure to test your app on Blockchain Testnet before going live. Truffle is a framework for Ethereum that provides a development environment. The framework supports a library which can link complex Ethereum apps and offer custom deployments to make contracts coding simpler. It supports some of the features mentioned below:.
You will find numerous tools that can be used to develop blockchain apps dApps and smart contracts. To know which is the best blockchain development tool for your project, consult our team of blockchain experts. The project is initiated with PoC, which typically takes weeks. Once the PoC is done, it takes weeks to develop a minimum viable product with bare minimum features. Launching an application on the mainnet takes around months based on the requirements of a client.
