Ethereum is the second valuable form of digital money after bitcoin. Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications.
It is one of the new technologies to help store and secure data and remove the costs that come with third parties. Under the Ethereum, servers and clouds are replaced by thousands of nodes run by volunteers from across the globe.
For example, an individual wants to purchase a home from another person. Traditionally there are multiple third parties involved in the exchange including lawyers and agents which makes the process unnecessarily slow and expensive.
With Ethereum, a piece of code could automatically transfer the home ownership to the buyer on expiration day and the funds to the seller after a deal is agreed upon without needing a third party to execute on their behalf.
Immutability: In the concept of “World Computer”, no third party can make changes to data.
Secure: Applications are protected against hacking attacks and fraudulent activities by using cryptography.
Zero downtime: Apps cannot be turned off at anytime and anywhere.
