Ethereum is a popular alternative coin (altcoin).
Before we get into the details, here’s a quick explanation: it’s an open-source, blockchain-based platform that allows developers to build and deploy decentralized applications (DApps).
It’s not just a cryptocurrency, but an entire ecosystem that supports a wide range of applications beyond simple financial transactions.
The birth of Ethereum
Ethereum was proposed in late 2013 by cryptocurrency researcher and programmer Vitalik Buterin.
Ethereum was developed by the Ethereum Foundation, a Swiss non-profit organization, with contributions from brilliant minds around the world.
Ethereum was officially launched in July 2015 and has significantly changed the blockchain landscape.
The birth of Ethereum was as transformative for the world of blockchain and cryptocurrency as the emergence of the first cryptocurrency.

How Ethereum works and blockchain
To understand how Ethereum works, we need to look at two key concepts: Ethereum’s blockchain and smart contracts.
Like Bitcoin, Ethereum operates on a blockchain network.
Ethereum’s blockchain is a transparent, immutable ledger of all transactions that have occurred on the network.
Unlike Bitcoin, however, Ethereum’s blockchain can store more complex information, such as computer programs or “contracts.
Smart contract definition and benefits
A smart contract is a self-executing contract where the terms of the agreement are written in code.
Smart contracts automatically execute transactions without an intermediary, reducing the risk of fraud and providing a level of transparency that traditional contracts can’t match.
Smart contracts offer a number of benefits, including speed (transactions happen in real time), accuracy (eliminates human error), trust (immutable records), and cost savings (no intermediaries).
What is an Ethereum Virtual Machine (EVM)?
Ethereum-enabled virtual machines (EVMs) are a critical component of Ethereum’s ecosystem.
It’s the runtime environment where smart contracts run.
EVMs make the process of creating blockchain applications easier and more efficient than ever before.
It ensures that programs don’t interfere with each other and prevents poorly designed applications from bringing down the network.
Ethereum tokens (ETH and ERC-20)
Ether (ETH)
Ether is Ethereum’s platform native cryptocurrency.
Ether serves as fuel for network operations and rewards miners for their computing services.
Ether can be used for a variety of purposes, including facilitating transactions within dapps, peer-to-peer payments, and as a store of value.
ERC-20 tokens
ERC-20 tokens are cryptocurrencies created on Ethereum’s platform.
They follow a list of standards that allow them to interact seamlessly with other tokens.
Decentralized applications (DApps)
DApps are applications that run on a network of peer-to-peer computers rather than on a single computer.
This is an important part of Ethereum’s appeal and potential.
DApps cover a wide range of services, from games like CryptoKitties to financial services platforms like Uniswap.
Dapps represent a new wave of software that leverages the trust, transparency, and efficiency of blockchain technology.
Ethereum 2.0: The Future
Ethereum 2.0, or Ether2, is the next major update to the Ethereum network.
It aims to improve the network’s scalability, security, and sustainability.
It includes upgrades like the Proof of Stake (PoS) consensus mechanism and sharded chains, and aims to process transactions faster and reduce energy consumption.
Ethereum has revolutionized the way we perceive and interact with blockchain technology.
By supporting decentralized applications and smart contracts, Ethereum has opened up a world of endless possibilities.
With the release of Ethereum 2.0, we can expect even more improvements and innovations in the blockchain space.
