A Guide to Building Your First Decentralized Application Web 3.0 is here! Welcome to the dark side of web and mobile development (in a good way). Lets talk about how we can use blockchains, distributed hash tables, and peer to peer protocols to create decentralized applications! Facebook: facebook.com/sirajology Instagram: instagram.com/sirajraval/ Instagram: instagram.com/sirajraval/ Credits to Mahesh Murthy for the code and inspiration: www.zastrin.com Thanks siraj, i dont understand what i should download for use the testnet and the solidity code. Can you tell me :) makes no sense whatsoever....sorry dude... Sorry, but it is like some of sci-fi. Currenty local bitcoins blocks require several GB to be operated. You want to create IPFS. How are you going to provide copies of billions of websites. Man, stop walk in the sky. Go to the Earth. Bro, you are the best. Thank you for taking time out of your life to teach us all this. Anyone else getting an error on this? I've been thru this over and over again and can't get it to work. When I ask in forums, they say it's outdated. The problem is getting the .html to connect to the contract. When I type in: VotingContract = web3.eth.contract(abiDefinition) I get: TypeError: web3.eth.contract is not a function Seems that I can't get the id to connect them: From the .html file: // In your nodejs console, execute contractInstance.address to get the address at which the contract is deployed and change the line below to use your deployed address contractInstance = VotingContract.at('0x2a9c1d265d06d47e8f7b00ffa987c9185aecf672'); I can't seem to get answers from forums except the this tutorial is outdated. It seems I need to the nodejs command to get the contractInstance. do you know powh3d.io? its an awsome dapp! the best stuff on b Continue reading >>

Blockchain - Wikipedia

Blockchain - Wikipedia

For other uses, see Block chain (disambiguation) . Blockchain formation. The main chain (black) consists of the longest series of blocks from the genesis block (green) to the current block. Orphan blocks (purple) exist outside of the main chain. A blockchain [1] [2] [3] originally block chain [4] [5] is a continuously growing list of records , called blocks, which are linked and secured using cryptography . [1] [6] Each block typically contains a hash pointer as a link to a previous block, [6] a timestamp and transaction data. [7] By design, blockchains are inherently resistant to modification of the data. Harvard Business Review defines it as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way." [8] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance . Decentralized consensus has therefore been achieved with a blockchain. [9] This makes blockchains potentially suitable for the recording of events, medical records, [10] [11] and other records management activities, such as identity management , [12] [13] [14] transaction processing , documenting provenance , or food traceability . [15] The first blockchain was conceptualised in 2008 by an anonymous person or group known as Satoshi Nakamoto and implemented in 2009 as a core component of bitcoin where it serves as the public ledger for all transactions.

Ethereum Basics & Ticket Service Example For Newbies

Ethereum Basics & Ticket Service Example For Newbies

When I've started learning about crypto currencies next after bitcoin was researching about Ethernum and how it works. It was a next move based on logic as Ethernum is 2nd crypto after Bitcoin by market share so I've decided to check it out. First of all I was highly interested why it was so different and they were talking about when talking about Ethernum. After that I've found this guy Siraj Raval on YouTube that has very high quality videos about Ethernum. I'm sure that you guys will enjoy how he explain things. One of the videos that I would like to share today is one that talks about pretty much basic difference between Bitcoin and explains Ethernum basics. One of the basic difference is that on Eth you can build up decentralized applications and one of the main differences is that ETH is actually programmable blockchain while BTC isn't. It can store information, scripts, contracts and much more... Take your time and watch this video, it will help you understand what is all about. Continue reading >>

Full Stack Hello World Voting Ethereum Dapp Tutorialpart1

Full Stack Hello World Voting Ethereum Dapp Tutorialpart1

Techie, Foodie, Traveler, Tinkering with Blockchain at www.zastrin.com Full Stack Hello World Voting Ethereum Dapp Tutorial Part1 In my previous post , I explained the high level architecture of Ethereum platform comparing it to a web application. As a developer, the best way to learn any new technology is by diving in and building toy applications. In this post, lets build a simple Hello World! application which is a Voting application. The application is extremely simple, all it does is initialize a set of contestants, let anyone vote for the candidates and display the total votes received by each candidate. The goal is not to just code an application but to learn the process of compiling, deploying and interacting with it. I have deliberately avoided using any dapp frameworks to build this application because the frameworks abstract away lot of the details and you fail to understand the internals of the system. Also, when you do use a framework, you will have more appreciation for all the heavy lifting the framework does for you! In lot of ways, this article is a continuation of the previous post . If you are new to the world of Ethereum, I recommend reading it before continuing. Learn the process of writing a contract, compiling it and deploying it in your development environment. Interact with the contract on the blockchain through a nodejs console. Interact with the contract through a simple web page to display the vote counts and vote for candidates through the page. The entire application set up and build was done on a fresh installation of ubuntu 16.04 xenial. I have set up and tested the application on macos as well. This is how I would visualize this application we are going to build. 1. Setting up the development environment Instead of developing the app ag Continue reading >>

Ethereum And Bitcoin Cash Are Soaring Despite A Broader Selloff

Ethereum And Bitcoin Cash Are Soaring Despite A Broader Selloff

Ethereum and Bitcoin Cash Are Soaring Despite A Broader Selloff Bitcoin has posted losses for the third straight session in a row, while Ethereum and bitcoin cash gained further momentum in Wednesday trade. Several other cryptocurrencies are also declining, due to traders concerns over the future of digital currency. After strong gains in the last two days, Ethereum has gained close to 12.8% in Wednesday trade. Bitcoin Cash also increased sharply by 12.3% in the last 24 hours. Litecoin fell almost 2.5%, while and Ripple dipped sharply for the third successive day. Following the latest selloff in Ripple price, Ethereum now holds the second place in term of market capitalization. Although Ethereum offers lower transaction fees and shorter transaction wait times, the recent glitch in its algorithm to evaluate costs has forced several users to pay considerably higher fees than usual. In an email to CoinDesk.com, developer Nick Johnson explained that many popular walletsincluding MyEtherWallet, MetaMask, and Shapeshiftuse what is called a gas oracle to calculate transaction fees. Lower fees and minimum wait time led bitcoin cash to become an alternate of Bitcoin. It was launched in August 2017 and it is hard-fork of Bitcoin. The stock price of Kodak has increased more than 200% in the last two days, while investors have welcomed its move of using blockchain technology. The growth in the value of bitcoin cash is supported by Overstock.com, which amalgamated bitcoin cash with bitcoin. It is currently standing at the fourth spot in terms of market capitalization. Its market capitalization stands around $45.8 billion, trailing just behind ripple, ethereum, and bitcoin. Excluding ethereum and bitcoin cash, the majority of cryptocurrencies suffered big losses since the start of t Continue reading >>

Ethereum - Proficient User - Super Dapps

Introduction to DApps (technical): Building a decentralized conference ticket purchasing web app by Siraj Raval: How to code a decentralized application or DApps: Any proficient user like you would want to play with some DApps or even smart contracts. But, what exactly is a smart contract? Smart contracts are computer code that helps automate the network without the need for a middleman. Smart contracts also work by keeping blockchain features intact, i.e., transparent. We wont be sharing an in-depth guide on smart contract, but we love sharing links to amazing online information! Smart contracts beginners guide: How Do Ethereum Smart Contracts Work? If you are deep into Ethereum or any blockchain related project, you will find GitHub term mentioned in a lot of places. Thats why we will be covering some basics of GitHub and share some useful information. Before we start sharing links, lets understand more about GitHub. GitHub is a version control system for projects and is mainly used for hosting computer code. It supports source code management (SCM) and distributed version control. It recently got acquired by Microsoft. So, what does that mean for you? It means that you can download code and then examine it. Some projects are also hosted on GitHub and need to be download and installed through GitHub. GitHub can also be shared for sharing structure information which can be managed by one or more people. The good news is that there are plenty of amazing GitHub guides. Lets list them below. Awesome Blockchain Link 2: Ethereum, just like other blockchain technologies, wants to reach as many people as possible. To do this, it needs to do more transactions per second. However, it only supports 15 transactions per second which is low compared to the current standards. In co Continue reading >>

Crypto Gaming Is Not (always) A Scam

Crypto Gaming Is Not (always) A Scam

Big risk, big reward or loss. Here are some tips and dispelled myths that every crypto gamer should know. Why did people ever put games on a blockchain? Theres a standard answer: because blockchain cryptographically ensures true and absolute ownership of items, and it makes games trustless and transparent. Now, in reality, these are ideals that games strive for, not hard facts to be taken for granted. In the face of scams, vapid and risky hot potato games, and dysfunctional development team, its been hard to onboard newcomers to the world of blockchain gaming.

Learn Blockchain For 6 Weeks Or Dietrying

Learn Blockchain For 6 Weeks Or Dietrying

Photo by S O C I A L. C U T on Unsplash I started my Blockchain career more than a year ago, it was a spontaneous decision I got a random interview and had a few days to prepare. During these days I read a lot of docs, watched a huge amount of videos on YouTube, tutorials and simple courses about smart contracts, algorithms, math and blockchain technology. These days were saturated with Blockchain, but it was interesting. I failed that interview, but I got a challenge to become a Blockchain developer as fast as I can. After a few weeks, I started a Blockchain developer career. I worked as Blockchain developer and Smart Contract developer and security auditor in few firms, and as Technical Blockchain analyst at ICORating team, now I'm continuing working as Smart Contract security auditor and Technical analyst, doing researches based on Blockchain and new Technologies appearing on Blockchain. The blockchain is full of interesting obstacles and new opportunities, I think its our future with a lot of other interesting technologies like VR, AR, MR, Machine Learning, etc. Here is a 6-week program for learning Blockchain, of course, you can finish it faster or you can skip some parts like the first week or last weeks where will be a lot of coding. So lets dive on it! I recommend you to start from Cryptography, it will help you to better understand all the next concepts and technologies. However, if you dont have a goal to delve into the technology and math, you can skip this section. Here are the simple encoding and decoding functions in Python. You need to understand what is hash functions, what is the difference between them, why different Blockchains use sometimes different hash functions and sometimes similar hash functions, how cryptography used in Blockchain.
