What is Ethereum (ETH) and When Was It Launched?

Ethereum is one of the most important cryptocurrencies in the world, often described as a more advanced version of Bitcoin. While Bitcoin primarily functions as a digital currency and store of value, Ethereum is designed as a smart contract platform, enabling developers to create decentralized applications (dApps) and issue custom tokens on its blockchain. The native cryptocurrency of the network is called Ether (ETH), which is used to pay transaction fees and power smart contracts.

Ethereum was officially launched on July 30, 2015, after its concept was publicly introduced in early 2014. Since then, Ethereum has become the second-largest cryptocurrency by market capitalization, right behind Bitcoin. Its programmability and wide range of use cases—from decentralized finance (DeFi) to NFTs—have made it one of the most innovative and widely adopted blockchain projects globally.

Who Created Ethereum?

Ethereum was created by Vitalik Buterin, a Russian-Canadian programmer who was deeply involved in the crypto community as early as 2011. Buterin initially contributed to Bitcoin Magazine, but he envisioned a blockchain that could do more than just financial transactions. His idea was to create a platform for smart contracts—self-executing pieces of code that run automatically when certain conditions are met.

Buterin’s vision was backed by several co-founders, including Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin. Together, they developed Ethereum and introduced it through one of the earliest and most successful Initial Coin Offerings (ICOs).

Although Vitalik Buterin is recognized as the creator, Ethereum itself is decentralized, meaning no single person or organization owns it. Anyone holding ETH or building on the platform contributes to its development and growth.

How to Buy and Sell Ethereum (ETH)?

Ethereum is one of the most widely available cryptocurrencies on both local and international exchanges. In Turkey, ETH is listed on exchanges such as BtcTurk, Paribu, Bitci, and Narkasa, while global platforms like Binance, Coinbase, and Bitstamp also support ETH trading.

Steps to buy Ethereum:

1. Choose a reliable crypto exchange that lists ETH.

2. Sign up and verify your account by providing the required documents.

3. Deposit funds: In Turkey, deposits are usually done via bank transfer or Papara. On international exchanges, credit and debit cards are also accepted.

4. Buy Ethereum (ETH) by entering the amount you want to purchase and confirming the transaction.

Selling ETH is just as straightforward. You simply select the amount of ETH you wish to sell on your exchange’s sell page, and the equivalent fiat or stablecoin will be credited to your account.

Ethereum Mining: How Does It Work?

Ethereum mining was historically one of the key ways to acquire ETH. It relied on the Ethash algorithm, which was optimized for GPUs rather than specialized ASIC hardware. This allowed many individuals to mine ETH using consumer-grade computers with powerful graphics cards.

However, Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in September 2022 with the upgrade known as The Merge. As a result, Ethereum mining no longer exists. Instead, ETH holders can now stake their coins to help secure the network and earn staking rewards.

Before The Merge, mining required powerful GPUs, significant electricity consumption, and specialized software. Today, staking ETH has replaced mining as the way to earn passive income from Ethereum. Investors can stake their ETH directly on-chain or through exchanges like Binance, Coinbase, and Kraken.

Why is Ethereum Important?

Ethereum introduced concepts that have transformed the entire cryptocurrency industry:

• Smart Contracts: Automated, self-executing programs that enable trustless transactions.

• DeFi Ecosystem: Ethereum hosts the majority of decentralized finance applications.

• NFTs: Non-Fungible Tokens, which gained massive popularity, are mostly built on Ethereum.

• Developer Flexibility: Unlike Bitcoin, Ethereum is programmable, allowing innovation across multiple industries.

This versatility has made Ethereum the foundation for thousands of blockchain projects, and despite growing competition from Solana, Cardano, and others, Ethereum remains the leading smart contract platform.
