Let's Create A Blockchain With PHP
 
55:45
Blockchain, Cryptocurrency. Bitcoin, Ethereum. Buzzwords? Trendy topics? Sure. As a developer, I'm not very interested in the hype or the crazy speculation. But I want to understand the underlying technology. How Bitcoin works. What makes Ethereum useful. The concepts and algorithms used by Bitcoin, Ethereum, and the thousands other coins that were created in the last years. I read the Bitcoin whitepaper. I found it very interesting. To share my new knowledge, I'd like to create a cryptocurrency in PHP... with you. One hour should be more than enough. Along the way, you will hopefully better understand what makes Bitcoin revolutionary.

Frontend Web Applications On Ethereum 1 - TestRPC and Web3.js | Blockchain
 
24:43
Ethereum allows you to create powerful smart contracts on the blockchain. The true power of Ethereum though, is the ability to create complex, decentralized applications or DApps. A great DApp ties smart contracts with an intunitive user-interface that allows the average user to leverage the power of the Ethereum network. In this video we begin to explore how to implement a web frontend that talks to our smart contracts deployed on the blockchain.

How To Send Ethereum Transactions
 
03:30
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.

Tutorial dapp with Solidity, Truffle, Web3 and Javascript
 
36:08
In this video, I tried to explain how to make simple dapp, app based on blockchain and Ethereum platform. App is consistent from Backend part smart contract written in Solidity using framework Truffle. Solidity is Ethereum language for writing smart contracts and Truffle is the most popular development framework for Ethereum with a mission to make your life a whole lot easier. During development we use testrpc. Testrpc is a Node.js based Ethereum client for testing and development. It uses ethereumjs to simulate full client behavior and make developing Ethereum applications much faster. It also includes all popular RPC functions and features (like events) and can be run deterministically to make development a breeze. In these way, we work on the local test network, not on the real network where we would spend real Gas. We use web3 to make your app work on Ethereum. Web3 object provided by the web3.js library. Under the hood, it communicates to a local node through RPC calls. web3.js works with any Ethereum node, which exposes an RPC layer. In frontend we connect with web3 we interact with backend blockchain and performing certain transactions. Then in standard way, we represent it in frontend with JS. For serving app we use Lite-Server Lightweight development only node server that serves a web app, opens it in the browser, refreshes when html or javascript change, injects CSS changes using sockets, and has a fallback page when a route is not found.

The History of Ethereum
 
08:11
The History of Ethereum - https://www.blockgeeks.com After Satoshi released Bitcoin to the world in 2008, a community of blockchain developers and researchers started to take shape around it. Many developers contributed to the open-source development of Bitcoin. Several magazines and online blogs also started to appear, writing about interesting projects and new ideas in the space. One of the members of this community was a Canadian teenager named Vitalik Buterin who worked as a writer for a publication called Bitcoin Magazine. As he was watching the ecosystem take shape, he noticed a common problem among projects: that many of them needed to start their own blockchain. This got Vitalik wondering: wouldn’t it be nice to have one single blockchain that everyone could build their applications on, just like we have one single internet that everyone can build their websites on. Instead of figuring out how to start a blockchain, developers would then be able to focus on building their own applications. So in late 2013, Vitalik published the Ethereum whitepaper which built on many concepts from Bitcoin. The whitepaper is available today on the Ethereum Github page. In the paper, he outlined the limitations of the Bitcoin blockchain and proposed a new general-purpose blockchain that could be used as a decentralized application platform. Ethereum would be able to do everything Bitcoin could, like sending transactions between accounts, and a whole lot more. The main issue with Bitcoin was the lack of a general-purpose programming language that would allow you to create any sort of application on top of its blockchain. Bitcoin scripts are not Turing-complete, meaning you cant write simple structures like loops, and they are also limited in capability because they cant store state. These scripts are also referred to as simple versions of smart contracts. The Ethereum whitepaper described its own native currency called ether and a new runtime environment for smart contracts, called the Ethereum Virtual Machine, or EVM. A subsequent yellowpaper was released in mid-2014 by collaborator Gavin Wood that would define the technical specification of the EVM and how it would work. The yellowpaper was used to create several open-source implementations in different languages, the most popular one being the Go language client, also known as geth. The second most popular implementation was written in the Rust language and is called the Parity client. Anyone running a client is a node in the Ethereum network, which currently has over 25 thousand nodes around the world. Smart contracts are just application logic that can be expressed using the operations defined in the EVM, and they can also store data on the blockchain. EVM opcodes are low-level machine language which isn’t very human-readable, so developers write smart contracts in high-level languages that compile down to EVM opcodes. Several high-level languages exist like Serpent and Viper, but the most popular one today is called Solidity and it has a syntax similar to Javascript. Smart contracts can contain some data as well as code that manipulates that data. You can think of a smart contract like a class that has fields and methods. Anyone can use Solidity to write a smart contract and deploy it to the Ethereum blockchain using a simple transaction. You would do this by compiling your Solidity smart contract down to EVM bytecode, and then sending the bytecode as part of a transaction to the Ethereum network. Once the transaction gets mined, the smart contract is deployed to the blockchain and given a public address. Anyone can then interact with the smart contract by sending transactions to its address and specifying which method they want to invoke. The result of the method call is written to the blockchain after the transaction is mined. There is also a cost associated with invoking a smart contract method called gas. Gas is just a unit of measurement that determines how much computation an EVM opcode requires. The price of one unit of gas is set in ether, and is known as the gas price. The gas price is used to calculate the total transaction fee for invoking a method call based on how much gas it requires, and it must be paid by the sender of the transaction. An interesting thing to note is that any transaction that invokes a smart contract method gets executed on every single Ethereum node. This means that in order to mine a transaction into a block, you have to invoke any smart contract methods for it as well. In this sense, Ethereum can be thought of as a decentralized world computer where you pay for computation using ether. To read more, be sure to visit us at www.blockgeeks.com

DrupalCon Baltimore 2017: Drupal and the Ethereum Blockchain
 
29:23
Blockchains have received a lot of media attention recently and are being explored by a range of organizations from financial services to NGOs. A blockchain can provide an immutable layer of trust to web applications by being a distributed ledger that is a tamper-proof history of all transactions sent to it. In this session I present a initial approach integrating the Ethereum blockchain with Drupal. While blockchain is a peer-to-peer technology that can be used in fully decentralized p2p architectures, I would like to explore a semi-decentralized Drupal architecture that can still provide the benefit of trusted transactions within a group of known participants–which can be Drupal User Accounts. This talk aims to answer Dries' question “What the Blockchain mean for a CMS like Drupal?” and provide an overview of the following: Blockchains Current state of blockchain applications What role Drupal might play in blockchain tech Drupal Ethereum Module: Current State and Roadmap Ethereum is an open source blockchain platform that is programmable via smart contracts. These are programs deployed to and executed on the blockchain that can enforce simple agreements between parties about resources represented. Decentralized applications that integrate smart contracts have wide applicability to digital identity, IoT, voting, asset tracking, revenue models for digital content, public and private records and more. Integration with Drupal would allow organizations to integrate Ethereum into their user registries workflows and begin to explore blockchain's benefits.
