Ethereum is basically open source software that is backed up by the block chain technology; it allows developer build and deploys decentralized applications. You can use Ethereum to build decentralized applications and gain reward of ethers for it that you can use for transactions with in the cryptocurrency ecosystem. Ethereum eliminates the need to build a new block chain when you want to create decentralized applications. These applications that run on block chains would often take an ample amount of time, especially when it comes to creation transactions decentralized applications.
So instead of building from the beginning all over again you can now use Ethereum to build decentralized applications. And in doing this you can actually earn ether, which is a crytocurrency and can also be used in its ecosystem. Ethereum was created after bitcoin, according to its founder; he thought to create something that would enable developers use the block chain technology efficiently and easily, rather than creating one all over again. Creating decentralized applications with ethereum helps you prevent control and external influence on data stored or gathered. No one can change or influence any data.
Applications that are built on this decentralized system are very secure and re hacker proof. You can be sure of its safety and it cannot be hacked. Block chain technology has gone a long way to change the way we do things and set to even influence so many things in the long run. Another great benefit of using Ethereum to build decentralized applications is that it can never go down, and it cannot be switched off, it runs on its own and is basically controlled and own by all its users. Ethereum has gone ahead to encourage developers to build using its platform and also earn, making it easy for them to raise funds and carry out their projects, While this is relatively new, it has been most welcomed.
