What is Ethereum and what can you do with it?

Ethereum is a decentralized blockchain platform featuring intelligent contract features. The platform’s native cryptocurrency is ether (abbreviated as ETH). In terms of market capitalization, ether is the second most valuable cryptocurrency behind bitcoin. The program is open-source.

2013 saw the creation of Ethereum by programmer Vitalik Buterin. Gavin Wood, Joseph Lubin, Anthony Di Iorio, and Charles Hoskinson were among the other creators of Ethereum. Crowdfunding started the development process in 2014, and on July 30, 2015, the network was operational. Anyone may install permanent, irreversible decentralized applications on Ethereum and allow users to communicate with them. Applications for decentralized finance (DeFi) offer financial tools that do not rely on banks, brokerages, or exchanges as middlemen. This makes it easier to take out a loan against cryptocurrency holdings or lend them out for profit. On Ethereum, users can also create and trade non-fungible tokens (NFTs), which are tokens associated with certain digital assets like pictures. On top of the Ethereum blockchain, numerous other cryptocurrencies use the ERC-20 token standard, and they have made use of the platform for initial coin offerings.

In an update known as “the Merge,” Ethereum switched from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus method on September 15, 2022. As a result, Ethereum now uses 99% less energy.

What is Ethereum used for?

Excellent, but how about application cases for Ethereum? Ethereum’s public and permissionless blockchain fosters innovation, resulting in the birth of thousands of decentralized apps with a diverse range of use cases, including the ones we will examine here.

Decentralized Autonomous Organizations (DAO)

Ethereum was initially used in the real world for the establishment of Decentralized Autonomous Organizations (DAOs).

It is an organization kind that does not need a central authority, to put it briefly. One or more smart contracts contain the guidelines for utilizing DAOs; as a result, community vote is required for all choices.

In its most basic form, a decentralized autonomous organization (DAO) gives you total transparency over its structures and regulations and eliminates the need for a hierarchy. Equal opportunities are another benefit that a DAO provides to all of its members, irrespective of how long they have been a part of the group.

Decentralized Finance (DeFi)

Ethereum has several real-world applications, with decentralized finance (DeFi) being one among them. This platform offers an extensive array of features, such as smart contract-based decentralized loans, decentralized exchanges, and stablecoin generation.

Creating a financial ecosystem composed of little, interoperable applications—like Lego pieces—that work well together to provide a “big global solution” that does not depend on a single organization is one of the goals of decentralized finance.


Payments can be made with cryptocurrencies, such as Ethereum development and Bitcoin. Due to the features of blockchain and smart contracts, Ethereum is a particularly beneficial payment method.

Smart contracts have the ability to handle transactions by encoding every stage of the sale, eliminating the need to rely on the integrity of a bank or other third party. In this way, transaction data on the blockchain is accessible to anyone and can never be altered or duplicated because it is public and transparent.

Digital identity management

One of the things that worries me the most about society’s future is digital identity management. Ethereum smart contracts have made it possible to prevent data breaches and thefts as well as issues with digital information monopolies.


When discussing use cases, Ethereum co-creator Vitalik Buterin has often mentioned that his blockchain might be utilized to establish an open voting system that could be put into place in nations that are in danger or have fragile democracies.

Since every vote would be recorded in the blockchain and no one or organization could alter the records, Ethereum would make it impossible to rig the outcome of an election. Every vote would also be visible to all, allowing any group to compare and examine the election results.
