In today's world, our personal information is stored on servers and cloud hosting owned by other companies like Google, Amazon, and Facebook. While this arrangement has many conveniences, there are also many vulnerabilities. Governments and hackers can gain access to your files by hacking a third-party service and leaking, stealing, or changing your data.
The internet was always intended to have a decentralized structure, and a revolution has come with new technologies and tools, including blockchain, to reach this goal.
Ethereum is one of these technologies.
Bitcoin was created to shake up the online banking system and PayPal. Ethereum was developed to use blockchain to replace third parties on the internet, like companies that store complex financial data.
A World Computer
Ethereum has a focus on becoming a world computer to decentralize the client-server model.
Servers and cloud systems are substituted with thousands of nodes run by volunteers all over the world with Ethereum.
Their vision is to allow the functionality to people globally so that they can complete in a marketplace within the infrastructure.
With app stores, your personal data like your past purchases, credit card information, address, phone number, and other sensitive data is stored and controlled by a third-party company.
In addition, Google and Apple store, display, and censor the particular mobile apps you have access to download. There are also other services like Google Docs or Evernote for creating and storing documents.
Ethereum wants to return control of this data to the rightful owners and reinstate creative rights to the authors of the content. The idea is to give the rights back to the content owners so that apps can no longer suddenly be banned, or notebooks are not temporarily taken offline. The intent is to give control back to the user to make changes, not the entity.
A decentralized application is an open marketplace that connects providers and users directly without the interference of a third party like Google or Apple. There are no middlemen to store or manage a user's data. This can benefit users from having their information compromised, sold against their knowledge, used for the benefit of the company, censored, or otherwise misused.
Ethereum has three different kinds of decentralized applications include apps involving money, apps that manage money, and apps that include governance and voting systems.
Ethereum wants to restore the control that people had over their own data in the past and mold it with the easy to access information that we have become accustomed to today in the information age. Whenever you make changes, save, or delete notes, all of the network nodes make the changes too.
There are many people that are skeptical about this idea as it's not clear which particular blockchain applications will be secure, useful, or scalable and as convenient as the mobile applications we have today
