Beginner Resources For Dapp Development With Ethereum

Beginner Resources For Dapp Development With Ethereum

Beginner Resources for DApp Development with Ethereum Ive found that whats missing for developers coming to Ethereum are really good educational resources that cover everything from start to finish. In this post I will try to outline what I think is a good process of getting started developing DApps as well as link to a number of sites, articles and tools that I found helpful in the past so you hopefully wont have to spend as much time searching and can just focus on learning. Im going to assume you already know (roughly) what Ethereum is, if not I suggest checking out the official website and yellow paper , although you dont need to fully understand the latter in order to develop on the Ethereum platform. Instead I can also strongly recommend to read How does Ethereum work, anyway? . On a sidenote, one thing that really helped me to understand Proof of Work, a core concept of current Blockchain technology, was building a simple Blockchain implementation from scratch. You can follow this article to do that, although I suggest implementing it yourself (maybe even in a different language) instead of just copy-pasting the code. After that generic introduction to Blockchain and Ethereum a great resource for learning Solidity, the main language used for Smart Contracts on Ethereum, is CryptoZombies . It will take you through learning the language and writing your first Smart Contracts to develop a simple game, and is expanding with new lessons roughly every two weeks. For supporting resources you can refer to the Solidity docs . If you want to try out Solidity in your browser, you can use Remix or EthFiddle . Another important piece in the puzzle which youd probably want to learn right after going through the Solidity resources or CryptoZombies course is web3.js - Ethereums Continue reading >>

A Fun Way To Learn To Create Dapps In Solidity

A Fun Way To Learn To Create Dapps In Solidity

A Fun Way To Learn To Create Dapps In Solidity One of the reasons I am rooting for the Ethereum community to address many of its current issues (scalability being the big one) is that there is a clear developer platform opportunity for Ethereum. The Ethereum programming language Solidity is relatively easy to learn and Ethereum was designed from the ground up as an application platform. Ethereum applications, called Dapps (for decentralized apps), are starting to launch pretty regularly. If you want to learn how to create a Dapp in Solidity, you might try out this interactive coding game called Cryptozombies : CryptoZombies is an interactive code school that teaches you to write smart contracts in Solidity through building your own crypto-collectables game. Thanks to AVC community member William who showed this to me yesterday. There is a lot of naysaying out there suggesting that public blockchains and crypto arent good for anything other than speculating on token prices. That is dead wrong, but it is true that the immature state of the technology has made building useful things on top of this technology very hard. What we need to look for are efforts to make public blockchains more reliable, faster, and easier to build on. Those projects are out there and the fruits of all of that labor will come in due course. Continue reading >>

Learn Ethereum Game Development With Cryptozombies

Learn Ethereum Game Development With Cryptozombies

Learn Ethereum Game Development With CryptoZombies Learn Ethereum Game Development With CryptoZombies This has to be the funnest way to learn Solidity. Loom Network has just released the first lesson for CryptoZombies , an interactive code school that teaches you how to make your own Ethereum based crypto game using the programming language Solidity. Although there are already a few resources that teach people Solidity, there has never been something as fun and noob-friendly as CryptoZombies. The first chapter begins with the very basics and has you typing the first lines of code to create a smart contract. The left side of the page explains the concept and gives an example of how the code syntax should look. Then you are asked to use that concept to write your own lines of code in the code editor on the right side of the page. When youre done, the site will check your code and either let you continue to the next lesson or show you which line is incorrect. Each chapter adds another programming concept and makes it easy to understand without adding too much to read either. Theres enough of a challenge that youll be proud of yourself for passing a chapter on the first try, but its also not so challenging that you will get stuck and give up. Youll learn about arrays and structs and go into depth about the different types of functions. At the end of this lesson, youll get to put your code to the test and use it generate your own Zombie with a unique DNA and look based on the name you give it. You can even share your zombie on social media to show off your new Solidity programming skills! This is just the first lesson on CryptoZombies and they plan to release a new one every 2-3 weeks. I cant wait for the rest of the lessons and really hope that they will take you all the w Continue reading >>

Loom Network: A Blockchain Platform Live!

Loom Network: A Blockchain Platform Live!

Creators of CryptoZombies announced today that they are officially going live with Loom Network. Loom Networks tagline is building scalable blockchains for large-scale online games and social. They envision a future where online communities run entirely off blockchain; and large-scale online communities (such as FaceBook, Twitter, Reddit) and even MMOs are entirely community-driven and impossible to sensor. As a demonstration of the Loom Network, the team at Loomx.io created the worlds first DApp running off the Loom Network, DelegateCall . For those who arent familiar with the term DApp, its the term being used to describe decentralized apps that run on blockchain technology. DelegateCall is the first fully blockchain-based Q&A website running on a Loom Network DAppChain. In a nutshell its a platform that developers can build apps and games on top of. The closest thing I can compare it to is the Apple App Store. In more technical terms, according to an article on their website , DAppChain is anApplication Specific Sidechain, that runs parallel to a mainchain, Ethereum in this case. Its ruleset is customized based on the use-case, and its security is maintained by the mainchains consensus algorithm. There are 3 parts to the Loom Network launch today: Loom Tokens, DelegateCall Transfer Gateway, and the Loom SDK. A Loom Token is what you need to access all the apps and games on the Loom Network. Think of it like a lifetime membership to Disneyland that gets you into the theme park and gives you access to all the rides. Loom Tokens can be purchased on their website or through 3rd party resellers. The Loom Network is selling Loom Tokens for a promotional price of $1.99. Its actual price, listed on their website, is $4.99. No word on how long this promotion will last. Under Continue reading >>

Cryptozombies Lesson 4 Released! Zombie Battles & Monetizing Your Dapps : Ethdev

Cryptozombies Lesson 4 Released! Zombie Battles & Monetizing Your Dapps : Ethdev

It is pretty great. Answer checker is strict but other than that, it all works pretty well. The tutorial will introduce a concept, tell you the syntax/how it works with an example and explanation, then tell you what you specifically need to do for the game. You have to figure out how to specifically implement the new concept, being provided the necessary parameters, so it takes some thinking. Really helps learn when you have to think. Like the other guy said, you definitely need some coding background (although mine is admittedly light with a focus on C# + a little solidity and I am doing alright) but it is a great way to learn the solidity syntax. It is probably beneficial to use another resource in addition to this tutorial. It can get a bit complicated so it is helpful to go back over the older scripts, and I'm pretty sure you can redo chapters if you re having trouble understanding something. I have been doing this tutorial on top of taking a Udemy dApp course and it's been pretty good. Of course, cryptozombies focuses a lot more on the solidity aspect. I definitely reccomend checking it out and seeing how it works for you. Continue reading >>

Want To Learn Solidity? There Is A Dapp For That

Want To Learn Solidity? There Is A Dapp For That

With so much emphasis being placed on the need for solidity developers for Ethereum smart contracts , you may be wondering how you can easily and effectively learn the Solidity language. Thankfully, there is a really helpful and fun way to learn the language. That is through the use of an interesting platform called CryptoZombies . Released by the Loom Network , CryptoZombies helps users to learn the language through a quirky Ethereum powered zombie game. In a similar fashion to a number of other guided learning experiences such as codecademey , Cryptozombies takes users through the whole language from the basics through to more advanced topics. In the first lesson on the game, the user is taken through the setup of a basic contract such as the configuration, variables, data structure, arrays and events. Although the game is a guided coding experience, it is not for complete beginners to programming. Some understanding of another programming language is at least required in order to complete it without too much head scratching. Although the site does not promise that you will be able to code high value and complicated smart contracts, the game is no doubt a great way for you to break into solidity programming. While the site is well laid out and the lessons are semi intuitive, there are some areas that can be improved. Some of the explanations on the site require more descriptions and there are some confusing statements. An example of this is their description of how the operators will work. They go over how operators will work in Solidity such as addition, multiplication and subtraction. When it comes to exponents, they say that you can use operators such as 10^16. When the user enters the exponent of 10^16 however, they are greeted by an error. The user may be stuck Continue reading >>

Learning Ethereum Solidity Andrew B Coathup Medium

The following is my recommendation for learning Ethereum Solidity. (Expanded from an answer I gave on Reddit ). These are the best tutorials I have come across, which are generally (for an ecosystem constantly changing) up to date, and will give you a good foundation of Ethereum Solidity. Crypto Zombies is an online tutorial by Loom Network. Currently at Lesson 5. You build a series of smart contracts for non-fungible tokens (eventually build a dApp in future lessons), think CryptoKitties. It walks you through Solidity at a nice pace. Truffle Framework Next up is Truffle, an environment for developing and testing smart contracts. Pet Shop is an easy to follow tutorial and walks you through the truffle process including a smart contract, tests for the smart contract and a dApp. You also get to use MetaMask (thank you orange fox team). If you do want to develop smart contracts then you will likely use Truffle. As an aside, I use Visual Code ( ) as my code editor. Open Zeppelin Once you understand the basics of Truffle it is time to use Open Zeppelin. Open Zeppelin is an open source collection of smart contracts to build upon. Start with an ERC20 token, then have a look at their token sale smart contracts. The Open Zeppelin tests are great examples of smart contract testing to use for your own testing. Infura Infura hosts Ethereum nodes, making it easy for you to deploy to a testnet and mainnet. Try deploying the Truffle Pet Shop Tutorial to Ropsten and use MetaMask to interact with your dApp and host the dApp in a cloud service like Azure to test from other platforms. Mobile will be key for widespread adoption of dApps and Ethereum. Test your Truffle Pet Shop Tutorial on the various mobile dApp browsers, Cipher is currently the best in my opinion for dApps, Toshi (by Coi Continue reading >>

Learn Ethereum Solidity Programming Now With Free Site Cryptozombies

Learn Ethereum Solidity Programming Now With Free Site Cryptozombies

Ever wanted to learn Ethereum Solidity programming? Have you dreamed of becoming an Ethereum developer, and make your own smart contracts and Dapps? Dream no longer, as Loom Network has just released a fun and creative new learning platform called CryptoZombies . Learn all about the basics of Solidity through the guided development of an Ethereum -powered zombie game! Much like other gamified software development platforms like Codecademy and CodeCombat , CryptoZombies is a guided experience that covers all the basics of Solidity development. The first lesson of the program covers basic contract setup, data structures, variables, arrays, and events. While you probably will not come out of the experience one as a Solidity developer as the site promises, you will certainly leave knowing more than you did when you started. CryptoZombies is a guided experience, but it is not designed for those who are completely new to programming. The site recommends that you at least have a basic understanding of one other programming language. The code used in lesson one greatly resembles Java, C++, or C# code, so experience in one of these should help. While the site design is fairly well laid out and lesson are for the most part intuitive, the lessons are still not perfect just yet. Some of the explanations are not fully clear, and in some cases seem misleading on purpose. In the section that covers mathematical operations, the text explains that Solidity can perform addition like 1+1, multiplication like 2*2, and exponent operations like 10^16. If you enter 10^16 in the code editor, however, you will be faced with a bright red error message. What you should have done, apparently, is enter 10 ** 16, much like in Python or other languages. This is explained in a little code box, but th Continue reading >>

Where Can I Learn Solidity Ethereum?

Where Can I Learn Solidity Ethereum?

Today, learning solidity is a bit difficult, particularly if youre completely new to the Ethereum ecosystem. Six months ago there were almost no good resources on learning outside of the documentation. However, the ecosystem is beginning to improve and offering a lot of methods to learn, based on your preference: Books: There are now a few good books to learning about solidity development (and Ethereum in general). There is the Introducing Ethereum and Solidity as well as a booked called Ethereum (still in preview). If youre interested in blockchain in more detail, its hard to beat Mastering Bitcoin , which teaches the same foundational knowledge youll need in Ethereum. Online Courses: There are now a number of courses offered online to teach you Ethereum. Udemy has about a dozen courses from various lecturers , and B9lab has a full MOOC available to teach smart contract development . Online Tutorials: If youre more interested in just looking for some tutorials to start playing around, you can do some diving via Reddit and Medium. The best tutorials and sandboxes I have found are: The sample contracts via JPMorgan Quorum . They offer a full IDE for solidity development as well as half a dozen contracts to start experimenting with. This tutorial from Mahesh Murthy is still one of the best for launching your first ETH smart contract: Ethereum for web developers Mahesh Murthy Medium And if you want a lot of different resources, the reddit ethereum portal (maintained by the Ethereum founders) has a load of great information . Next week, I plan on producing a video on how to get started with development and plan on posting it here. Continue reading >>

Crypto Zombies Review

Crypto Zombies Review

Another "cryptogaming" project was launched recently. It's called Crypto Zombies. Developers call it a game, although in fact Crypto Zombies is a platform with a completely different purpose in mind. This is the school of crypto programming, where everyone can learn how to create blockchain games. Crypto Zombies is a free project where you can learn how to use Solidity language to create games on Ethereum blockchain. Crypto Zombies developers claim that their goal is to promote Ethereum and show the community that the blockchain can be used not only to store transactions data, but also as a basis for decentralized applications. But why the project was named Crypto Zombies? The answer is simple. The fact is that during the training students create their own Monster Factory. This is a proper blockchain game, which can be played immediately after completing the first class. In the second and subsequent classes, students add new functionality to their Monsters Factory, and the resulting project is not inferior to many popular blockchain entertainment platforms. However, you can play Crypto Zombies as well. Anyone who successfully completed the course and created his Monster Factory, gets an army of characters and can use them to fight other users' armies. If the battles are successful, the player receives a reward. Crypto Zombies is a completely free-of-charge project. Participants do not give a penny, but in return receive valuable knowledge about Solidity and begin to understand how to create decentralized games. There is an opportunity to take classes in a dozen languages, including English and Russian. In total there are four classes in Crypto Zombies school: Everyone who studies at Crypto Zombies can track their progress and understand what they need to work on. New c Continue reading >>
