What is Ethereum?

Ethereum, being a decentralized system, is fully autonomous and is not controlled by anyone at all. It has no central point of failure, as it is being run from thousands of volunteers’ computers around the globe, which means it can never go offline. Moreover, users’ personal information stays on their own computers, while content, such as apps, videos, etc., stays in full control of its creators without having to obey by the rules imposed by hosting services such as App Store and YouTube.

Ethereum took the technology behind Bitcoin and substantially expanded its capabilities. It is a whole network, with its own Internet browser, coding language and payment system. Most importantly, it enables users to create decentralized applications on Ethereum’s Blockchain.

is that it features additional applications, such as “smart contracts” and “crowdfunding.”

As it was mentioned before, Ethereum is a decentralized system, which means it utilizes a peer-to-peer approach. Every single interaction happens between and is supported only by the users taking part in it, with no controlling authority being involved.

In short, Ethereum is a public, open-source, Blockchain-based distributed software platform that allows developers to > build and deploy decentralized applications

How Ethereum works

Ethereum is based on Bitcoin’s protocol and its Blockchain design but is tweaked so that applications beyond money systems can be supported. The two Blockchains’ only similarity is that they store entire transaction histories of their respective networks, but Ethereum’s Blockchain does a lot more than that. Besides the history of transactions, every node on Ethereum network also needs to download the most recent state, or the current information, of each smart contract within the network, every user’s balance and all the smart contract code and where it’s stored.

Essentially, the Ethereum Blockchain can be described as a transaction-based state machine. When it comes to computer science, a state machine is defined as something capable of reading a series of inputs and transitioning to a new state based on those inputs. When transactions are executed, the machine transitions into another state.

Every state of Ethereum consists of millions of transactions. Those transactions are grouped to form ‘blocks,’ with each and every block being chained together with its previous blocks.

Advantages of Ethereum

Ethereum platform benefits from all the properties of the Blockchain technology that it runs on. It is completely immune to any third party interventions, which means that all the decentralized apps and DAOs deployed within the network can’t be controlled by anyone at all.

Any Blockchain network is formed around a principle of consensus, meaning that all the nodes within the system need to agree on every change made within it. This eliminates possibilities of fraud, corruption and makes the network tamper-proof.

The whole platform is decentralized, which means there is no possible single point of failure. Hence, all the apps will always stay online and never switch off. Moreover, the decentralized nature and cryptographic security make the Ethereum network well protected against possible hacking attacks and fraudulent activities.
