How to Build an Ethereum Blockchain Explorer Dapp
How to Build an Ethereum Blockchain Explorer Dapp - https://blockgeeks.com/ In this lesson we’re going to see how to build a simple dapp using the Ethereum blockchain as our backend We’re going to build a blockchain explorer, kind of like etherscan, but we’re only going to display the last 10 blocks on the chain. To do this, we’ll use an open-source framework called Ethers.io to quickly develop and deploy our dapp. Ethers comes with command line tools which are available as a node module and can be installed using npm install -g ethers-cli. Let’s install to our global context since we’ll probably use this across multiple projects. You can read more about Ethers by checking out their awesome documentation online. Ethers.io makes it easy to create dapps by allowing you to quickly run them locally during development. One of the things I really like is that it removes the need to have a copy of the blockchain, so we don’t need to run a local geth node for example in order to build dapps. Another thing I really like is that it comes with a free hosting service called ethers.space, where we can store some of our static files for free. We’ll see how to use this later, but for now we’ll just keep everything local. The first step is to create a new project folder for our dapp and navigate into it. We’ll call our project, explorer. To use the ethers.space hosting, we need to have an Ethereum account and we can create one by calling ethers-build init, which generates a keyfile for us called account.json. Make sure you use a strong password when encrypting your private key. Your keyfiles never leave your web browser’s local storage when using Ethers Now let’s start by building our front-end UI. We can create a new HTML file called index.html and define a head and body for our document. Let’s put hello world in the body, and we’ll also give our page a title. We can quickly spin up a local web server to serve this index.html by using the command ethers-build serve. By default, Ethers will point to the mainnet, but we can also pass the —testnet option to point to ropsten. This prints out a local http address where we can see our UI. Let’s paste this URL into a browser. We get some sort of view rendered, but this isn’t like anything we wrote in our HTML. We keep seeing this ‘loading application’ spinner because we haven’t included the ethers-app javascript in our document. Let’s add a script tag to the end of our body and link it to the minified ethers-app javascript. Now when we reload the page in the browser, we are at least able to see our Hello World message meaning our application is loading. There’s also a dashboard across the top of the page, but we didn’t actually write any of this in our index.html. This view is inserted by the Ethers.io container running locally. Through the Ethers.io container, we can serve multiple apps by passing the application URL at the end of the fragment. The part after the hashtag tells the Ethers.io container which application to load. Typically we would have to run the Ethers.io container over https, but it allows for running over http for development. The Ethers.io container provides a bunch of other tools for us like a messenger, a testnet faucet and even its own blockchain explorer, but we won’t get into these features right now. Let’s try displaying the last 10 blocks from the blockchain in our UI. We can replace our hello world text with an HTML table element that defines 3 column headers. We’ll print out each block’s number, hash and timestamp of creation. Let’s give our table an ID so we can reference it later in javascript and we’ll also set the width to 100% To read more, visit https://blockgeeks.com/

Blockchain tutorial 25: Testnet and faucets
This is part 25 of the Blockchain tutorial explaining what a testnet is and what faucets are. This tutorial explains the following: - what a testnet is - what the purpose is of a testnet - show you a Bitcoin testnet block explorer - show you an Ethereum testnet block explorer - what a Bitcoin testnet address looks like - what a faucet is In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

How To Send Ethereum Transactions
How To Send Ethereum Transactions http:///www.Blockgeeks.com You can send transactions between any two accounts on Ethereum. Typically, these transactions occur in the production environment called the Mainnet but there’s also a few test networks available for us to use. Test networks are useful when you want to use Ethereum without having to pay real money. Some of the popular test nets today are Ropsten, Rinkeby and Kovan. Properly functioning test environments are a critical part of the DAPP development process. Ropsten, which is the main public network and uses proof of work has become prone to spammy transactions and slowness. In response to this, two separate community efforts led to the creation of new test nets, Rinkeby and Kovan. These networks require authenticating using your GitHub account and the transactions are validated using proof of authority meaning there are a small set of validators. Let’s try to send a transaction over the Rinkeby test net. We’ll use a Chrome plugin called MetaMask to connect to the network and make transactions. I highly recommend getting MetaMask since it makes interacting with the Ethereum blockchain extremely easy. First, we’ll change the network to Rinkeby to make sure we’re using test ether and not real ether. Let’s create two test accounts and label them. To get test ether into these accounts, we need to use a tool called a Faucet which is just a website where you enter your address and it sends you some test ether. Let’s copy the address for one of our accounts. When we click the buy button, we get redirected to the Faucet. Since we’re connected to Rinkeby, we need to use our GitHub credentials to get the test ether. To do this, go to gist.github.com, create a new Gist with a single line that contains the address you just copied and publish it. You then copy the Gist URL and paste it into the Faucet. In a few short moments, we can see that we have updated the balance in our account. The reason the balance took a few seconds to update is because we need to wait for the transaction to get mined on the Rinkeby network. Now, let’s move this test ether between our accounts. First, let’s copy the address of our receiving account. Then, we click the send button, paste the address, as well as the amount and hit submit. Once we submit the transaction, we’re provided a transaction hash which we can use to reference this transaction. If we use an Ethereum blockchain explorer like Etherscan, we can get more details about this transaction. Since we made the transaction on the Rinkeby network, we have to use rinkeby.etherscan.io and we can see that the transaction is still waiting to be mined. Once it is successfully mined, we’ll see a block number assigned to the transaction. We can then verify the updated account balances using MetaMask.

Blockchain Explorer | How To Determine If A Cryptocurrency Is Real
https://www.freecryptominicourse.com | Use the link to the left to learn how and why bitcoin & cryptocurrency are changing the world and how you can massively profit from them. Check out the Blockchain Explorer to determine if the coin you are researching is a real cryptocurrency with a 'public ledger' blockchain behind it by using the following link: https://chainz.cryptoid.info/ In this video I explain how you can use a certain website to gain access to the 'Blockchain Explorer' and determine if a coin you are researching is actually a real cryptocurrency. If you are looking into putting money into a coin, you should determine that it has a public ledger blockchain first, because if it doesn't, it is not a real and you will want to stay very far away from it! It pays to to do your due diligence before getting involved with any cryptocurrency. Do your research! To read the full blog post about using the Blockchain Explorer to determine if a cryptocurrency is real, use the following link: https://www.whatisacryptocurrency.com/blockchain-explorer For more information, news and education on cryptocurrency visit: https://www.whatisacryptocurrency.com You can also read my blog post 'What Is A Cryptocurrency' for further insight into the history of crypto and where it's going with the second generation technology: https://www.meetcalebwright.com/cryptocurrency/what-is-cryptocurrency/ I wrote a follow up blog post here as well: http://www.meetcalebwright.com/cryptocurrency/what-is-a-cryptocurrency/ Have questions about Cryptocurrency? Wonder how you can start profiting with it and set yourself up to become one of the next cryptocurrency millionaires like many of us already are? I'd be happy to talk to you about that and answer your questions! Video Transcript: The Blockchain Explorer. This is the de facto way to determine if a coin that you are looking at is actually a real cryptocurrency. Caleb Wright here with What Is A Cryptocurrency dot com. And today I have decided to shoot a little video to help all of you out there who are researching the cryptocurrency industry, and to give you a tip that will keep you safe with how that you use your money when you decide to put it into a cryptocurrency coin. Make sure that your coin, or the coin that you are looking at and considering getting involved with is actually a real cryptocurrency that has a blockchain behind it. Because there are actually a bunch of companies out there who are promoting coins that they are actually distributing completely in house, which is illegal with the Securities and Exchanges Commission. And they seem to completely miss the point that a cryptocurrency is not just a digital currency, it's not just a digital unit. It has to have a blockchain technology behind it. Which is a public ledger which is accessible via the internet, by the public, hence the 'public ledger' name. And you can basically have access to all of the wallets and all the transactions that have happened within the blockchain of that cryptocurrency. So basically if a digital currency does not have a blockchain, it is not a cryptocurrency and you want to stay very far away from putting money into it until they actually get a cryptocurrency blockchain behind it and get it onto the publicly traded exchanges. So there is a website here that you can visit, it's called http://chainz.cryptoid.info that's c h a i n z dot c r y p t o i d dot info. And this website gives you access to the blockchain explorer of all the cryptocurrencies that are legit that are out there. As you can see we have a few of the popular coins right here at the top of the list. Litecoin and Capricoin and Rubycoin for example. And so you can also filter the list using this search bar up here, you can type in a specific coin that you are looking for, so you don't have to browse through this very long list of coins. Okay, then you can quickly determine if the coin you are looking at is real. Now to show you how you can navigate through this, and like I was telling you before how you can see any wallet that is in the blockchain and the transactions that have been made with these wallets. All you have to do is click on the coin. So I'm going to click Capricoin right here... (I couldn't fit the whole transcript, so please watch the video for the rest!) https://youtu.be/LnIytbmVOFY

Decentralized Storage Explained
Decentralized Storage Explained - https://blockgeeks.com/ In this lesson we’ll learn about decentralized storage and some services that are available today like IPFS and Swarm. You can think of decentralized storage as a peer-to-peer network where members pool together their disk space to create a shared global memory, kind of like Dropbox but decentralized. Both IPFS and Swarm are similar in that they are opensource decentralized storage solutions, but they differ in implementation and approach. IPFS, which stands for interplanetary file system, is a protocol that was published by an organization called Protocol Labs. The first implementation of the IPFS protocol was written in the Go language and published in early 2015, and today there are several alpha release implementations available including in javascript. Swarm is also a protocol, and is part of the Ethereum holy trinity that makes up the serverless world computer, which consists of Swarm, Ethereum and Whisper. These three infrastructure projects are part of a broader vision that provides a completely decentralized alternative to the currently centralized web. Ethereum would provide the computation power; Swarm would provide the storage layer; And Whisper would provide a messaging layer. Swarm and Whisper are not quite as far along in their roadmaps as Ethereum. But a proof-of-concept Swarm implementation written in the Go language is included as part of the geth client since version 1.5 You may have noticed I said that both projects are either in alpha or proof-of-concept stages, meaning theyre not quite yet ready for the production spotlight. But understanding the role of decentralized storage in the future web is important, so you should know how to make use of these tools. As these projects evolve and mature, they will become increasingly production ready. Let’s start by looking at how to use Swarm. Since Swarm is already part of the Ethereum stack, a proof-of-concept Go language implementation exists as part of geth. So to activate swarm, we need to download and build geth and swarm from source. To do this, we need to have Git and Go installed in our environment. You can do this easily using the command brew install go git. Then you need to make sure your Go environment is setup correctly. You can do this by creating a folder called go in your home folder, and then exporting an environment variable called $GOPATH which points to this folder. We’ll then install from source by downloading the go-ethereum source code from their github mkdir -p $GOPATH/src/github.com/ethereum cd $GOPATH/src/github.com/ethereum git clone https://github.com/ethereum/go-ethereum cd go-ethereum git checkout master go get github.com/ethereum/go-ethereum And now we can compile geth and swarm from source: go install -v ./cmd/geth go install -v ./cmd/swarm We’re now ready to run the swarm daemon by using the binary in our $GOPATH. You can add this bin folder to your PATH for convenience. If you run swarm version, we can see that we are on version 1.8. To use Swarm, you need to have an Ethereum account. You can do this quickly using geth account new. After entering a password, this will print out the new account address that we will use to join the Swarm network. You can copy the public address to your clipboard. To run Swarm we first need to make sure we have geth running. Then in a separate tab we run swarm and point it to our Ethereum account using the —bzzaccount option and pasting in our public address. It will prompt for your password to unlock the keyfile for Swarm, and then start up a local Swarm node on port 8500. Now we can easily upload files using swarm command line tools by simply calling swarm up followed by the path of the file you want to upload. Swarm doesn’t support encryption yet, so make sure you dont upload any sensitive files. After uploading, you’ll get a unique hash printed out for this file that points to it on the Swarm network. Let’s upload our index.html from our previous blockchain explorer example. To read more check out https://blockgeeks.com/

How To Create An Ethereum Smart Contract
How To Create An Ethereum Smart Contract https://blockgeeks.com The most interesting part of Ethereum are smart contracts. You can think of smart contracts like autonomous agents deployed onto the Ethereum blockchain. Smart contracts are made up of some data, as well as some code that manipulates that data. Just like a user account, smart contract accounts also have their own balance as well as a public address, which looks the same as the user account address. To interact with smart contracts, you send transactions to it with some extra data, to specify which function you want to invoke, as well as any input parameters for the function. The transaction will invoke the function, and return any possible output once it has been mined. We're going to be using Remix to write smart contracts, which is an online IDE, available for free at remix.ethereum.org. It comes with a compiler, editor and debugger for solidity. The great part is that you don't need to download or install or set up anything, you just go to this webpage and start writing smart contracts, which is awesome. The UI is divided into four main sections. The left part is our file explorer where we can open Solidity files from our hard drive. The middle section is our editor where we can view and write our source code. At the bottom we have a terminal which prints out important events and transactions, and the rightmost section contains some handy tools for compiling running and debugging our code. The first example we'll look at is a smart contract called Hodor. Let's load up the source code. You'll notice that Solidity source files end with the .sol extension. The syntax of Solidity resembles java script, so it should be fairly easy to pick up. The first we see at the top uses the pragma directive. This tells the compiler that the contract is written for a Solidity compiler version of at least [0.4.0 00:01:53], or anything newer that doesn't break functionality. We then have a multi-line comment block, briefly describing what this class does. The next line is where we declare the name of our smart contract using the contract keyword. We've simply called out class Hodor because, as you'll see, all it does is return a simple greeting. We also declared two state variables called Creator and Greeting. Creator has an address data type, which is used for storing addresses of accounts. Greeting is a string data type, which just stores some text greeting. We initialized both of these variables in our constructor. The constructor is declared using the function keyword, followed by the name of the class. The constructor is a special function that is invoked only once, when a contract is first deployed to the Ethereum blockchain. You can only declare a single constructor for a contract. We also inject the initial string greeting as a parameter, into the constructor, and set the greeting variable to that value. In the second line of the constructor, we initialize the creator variable to a value called message.sender, but if you look closely, you might wonder where this value came from, since it's not being injected into the constructor. This is because message is a global variable that provides certain information about the message, such as the address of the account sending it. We can get the address of the account creating the contract, using message.sender in the constructor. You may notice that we don't actually use this creator variable anywhere in our contract, because this is just a simple example. We could potentially use this information to implement access control to certain functions. We'll see an example of this later. Read more on Blockgeeks: https://blockgeeks.com
