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/

How to recover ERC20 Tokens sent to the Wrong Address
In this example I will go over how I accidentally sent GRX tokens to my Blockchain.info wallet by mistake and moved them to MyEtherWallet (MEW). You need to be in control of your private keys and do not send or share them with anyone. This technique will work will any ERC20 Tokens mistakenly sent to your Blockchain wallet and you needing to recover in you MEW wallet. *This will require getting the private keys of the receiving wallet or wallet seed. No way around it. Exporting private keys or seeds to MEW. Recovering bitcoin wallets might work the same if you have access to your private keys, it is always important to have a wallet that gives you access to your private keys, so you know you own the wallet. And you might be able to import them into MEW or blockchain wallets to recover tokens. **Overview instructions: if you do NOT have your private key, then you cannot recover. Get with wallet owner. 1. Copy private key from blockchain wallet, select ETH on leftside then select private key on right, next to search box. 2. Go to myetherwallet.com, logon using that private key you just copied, last option. 3. If you dont see your tokens you will need to add a custom token on the right side pane. Watch my video below "HOW TO ADD A CUSTOM TOKEN TO MYETHERWALLET, below. 4. Once you see your tokens, you will need to put some ETH in your wallet to be able to move your tokens out of it and into your current myetherwallet. About .50 cents should work, that will give you gas/gewi that is used to move ERC20 type tokens around. What no one tells you is that you always need ETH on hand for any ERC20 type token commerce. HOW TO ADD CUSTOM TOKENS TO MYETHERWALLET: https://www.youtube.com/watch?v=rAJNC_NtJgg&t=1s REMEMBER: CoinBase is NOT a WALLET, and any wallet that does not give you your private key means you do not own said wallet.I If you would like to follow along with my programs, please use my free sign up and like and sub: Get started, buy some bitcoin get $10, give $10, win/win! ☘️💰Coinbase: http://bit.ly/myC-B Asian exchange,https://www.bithumb.com If you are looking for a good exchange to buy other Alt coins I would recommend Binance. http://bit.ly/BNBexch GreenAddress Wallet- free segwit enabled wallet: https://greenaddress.it/en/wallet.html# Hardware wallets for the extra paranoid, very safe: Ledger Nano S: https://amzn.to/2xlbTuo Trezor Black: https://amzn.to/2L0egVf Remember do your own due diligence and only what you are comfortable with loosing, not a financial adviser. this is a risk, thanks! how to use regalcoin how to use blockchain bitconnect explained bitconnect coin bitconnect wallet bitconnect legit bitconnect deposit bitconnect withdraw bitconnect loan bitconnect stalking bitconnect full tutorial bitconnect community bitconnect scam usi-tech buying usi-tech deposit usi-tech forex usi-tech english usi-tech presentation usi-tech bitcoin usi-tech review usi-tech compensation plan usi-tech strategy usi-tech lee usi-tech scam cryptrade capital cryptrade withdraw cryptrade deposit cryptrade release cryptrade investment cryptrade review cryptrade tutorial cryptrade scam cryptrade wallet cryptrade capital erfahrungen cryp trade capital cryp trade withdraw cryp trade deposit cryp trade release cryp trade investment cryp trade review cryp trade tutorial cryp trade scam cryp trade wallet cryp trade capital erfahrungen chain group explain chain group tutorial chain group deposit chain group loan bitpetite how to bitpetite deposit bitpetite withdraw bitpetite review bitpetite coin bitpetite wallet bitpetite release bitpetite investment bitpetite loan bitpetite scam bitpetite legit bitpetite compensation plan bitpetite full tutorial how to deposit the meaning of life passive income how to withdraw how to lend regal coin ico regal coin review regal coin investment regal coin deposit regal coin white paper regal coin buy regal coin tutorial regal coin rec regal coin withdraw regal coin and bitconnect regal coin official regal coin scam hextracoin ico hextracoin review hextracoin investment hextracoin deposit hextracoin white paper hextracoin buy hextracoin tutorial hextracoin rec hextracoin withdraw hextracoin and bitconnect hextracoin official hextracoin scam hextracoin htx

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. To learn more about Ethereum, check out our online guides and courses at blockgeeks.com. Thanks for watching and see you next time.

Tutorial: Using a Block Chain eXplorer (BCX) to find tokens
Many people are entering the crypto space underprepared or learning through immersion - which is akin to baptism by fire. As you are your own bank and responsible for your own funds, its advantageous to learn how to use a BCX's to trace transactions. They are ugly and confusing at the moment, but they are also your eyes into this transparent yet pseudonymous space. ----------------------------------------------------------------------------------------------------------- This is not investment advice!

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

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
