Looking to get started with Ethereum Web Development? Ethereum is a blockchain based platform that runs smart contracts. The heart of it is based on the successful technology Bitcoin Blockchain, Ethereum runs decentralized smart contracts that function as decentralized applications that are programmed into the blockchain itself. Among web developers, it is rapidly being considered as Web 3.0. Ethereum allows developers to use current styling tools and technology mixed with the power of the Ethereum Computer to create unstoppable applications that cannot be interfered with. The project started in August 2014, with a pre-sale to jumpstart the coin. Over the last two years, Ethereum has gained a sizable amount of users and adopters looking to explore what the currency has to offer.
Most web developers are quite familiar with web applications and how the client/server architecture model operates, at least at a high level. Right now, web applications are housed at hosting providers like Azure, Amazon Web Services, Google App Engine, or a VPS/server combo. In this model, all of a company’s clients interact with one centralized application system. This allows clients to interact and utilize services from a variety of devices. When clients make a request to a service, the server does all the magic–such as accessing the database, caching systems, and returning data to the client. This current method is the gold standard for most development systems and works very well, at least most of the time. For certain applications, it would be more helpful if the application database was securely and publicly accessible by everyone, making it so one does not have to rely on the application owner to secure your data.
A good example of this is selling on Ebay. You may have a ton of great reviews for your store, but then Ebay suspends your account for whatever reason. This will severely impact your ability to do business, as it blocks you from access to all your collected data. It would be better if certain information, such as reviews, ranking, and ratings were stored in a public ledger that allows users to move platforms without losing hard work. If you could eliminate Ebay from the equation, you could save on the commissions and also not run the risk of losing access to your data if something unexpected happens.
Ethereum Dapps work very similarly to how our centralized applications work. The fundamental difference between the two is that each client communicates with a private instance of the application. There is no central server or hardware in which clients have to connect to. Each Client that interacts with a Dapp will need a complete copy of the Ethereum blockchain on the local device to start using the application. While it may sound a bit unusual at first, this method has major advantages over a centralized server system. You only need to download the blockchain a single time before using Ethereum, after that it will continually update with new blockchain records as smart contracts are processed on the network. The Dapps are embedded and run from the blockchain completely using the Ethereum computer.
The Ethereum Blockchain is broken up into two parts, the Database and Code.
In a nutshell, the blockchain stores your database, code and also runs your contract code in the Ethereum Virtual Machine. The code is hosted on the blockchain data each node connected to the Ethereum network.
This is just breaking the surface of what Ethereum and Dapps have to offer. There are still many interesting details about the inner workings of the blockchain that can be explored if you wish to learn more. We wanted to show how centralized web applications work when compared to Decentralized applications. It’s a bright future for the internet and Ethereum is leading the way in 2017.
