Introduction to Ethereum (ETH)

Ethereum, often denoted as ETH, is an open-source, blockchain-based platform that enables developers to build and deploy decentralized applications (dApps). It was proposed in late 2013 by Vitalik Buterin, a cryptocurrency researcher and programmer, and development was crowdfunded in 2014.

Ethereum’s Early Days

In the beginning, Ethereum aimed to build upon the pioneering technology behind Bitcoin, implementing a blockchain with a built-in Turing-complete programming language. This would enable users to create smart contracts—self-executing contracts that operate without the need for intermediaries. The Ethereum network went live on July 30, 2015, with 72 million pre-mined coins.

Ethereum’s Stages of Progress

Ethereum’s evolution can be characterized by several key stages, starting with “Frontier,” the initial live release. This was followed by “Homestead” in 2016, which saw improved transaction processing, contract creation, and log filtering. The “Metropolis” stage came in two parts, “Byzantium” and “Constantinople,” and brought improvements to contract flexibility and security.

The DAO Hack

2016 was a tumultuous year for Ethereum due to the infamous DAO hack. The DAO (Decentralized Autonomous Organization) was a complex smart contract on the Ethereum network that was designed to revolutionize how Ethereum projects were funded. However, an attacker exploited a vulnerability in its code and drained a third of the DAO’s funds. This incident led to a hard fork in the Ethereum blockchain, creating two separate chains – Ethereum (ETH) and Ethereum Classic (ETC).

The Ethereum Merge upgrade: Transition from PoW to PoS consensus

The Ethereum Merge marks Ethereum’s transition from a Proof-of-Work (PoW) consensus mechanism to a Proof-of-Stake (PoS) one. This is an integral part of Ethereum’s move to Ethereum 2.0 (or Eth2), which is aimed at improving the scalability, security, and sustainability of the network. The Merge brings us closer to a more environmentally friendly and scalable Ethereum.

Ethereum Price History

Ethereum’s price has seen significant volatility since its inception, reflecting the typical highs and lows of cryptocurrency markets. It started trading at around $0.31 in 2015 and experienced its first major surge in 2017 during the initial coin offering (ICO) boom, peaking at over $1,400. After enduring the subsequent crypto winter, Ethereum reached new all-time highs in 2021, going above $4,000.

Ethereum’s Future After the Merge

The future of Ethereum after the Merge looks promising. With the transition to PoS, Ethereum is expected to become more scalable, handling more transactions per second, thereby becoming more attractive for developers and users. Furthermore, Ethereum’s shift to a PoS consensus mechanism is expected to drastically reduce its energy consumption, making it more sustainable.


From its inception to the impending Merge upgrade, Ethereum has significantly impacted the cryptocurrency space by enabling decentralized applications and smart contracts. Its evolution continues to shape the future of blockchain technology and the wider world of decentralization.


1. What is Ethereum’s main innovation? Ethereum’s main innovation is its ability to execute smart contracts on its blockchain, enabling the development of decentralized applications.

2. What was the DAO hack? The DAO hack was a major theft of cryptocurrency that occurred in 2016 when an attacker exploited a vulnerability in the DAO, a smart contract on the Ethereum network.

3. What is Ethereum 2.0? Ethereum 2.0, or Eth2, is an upgrade to the Ethereum blockchain that aims to improve its scalability, security, and sustainability.

4. What’s the difference between Ethereum and Ethereum Classic? Ethereum and Ethereum Classic are the result of a hard fork following the DAO hack. Ethereum (ETH) is the chain where the DAO hack was reversed, and Ethereum Classic (ETC) is the original chain where the hack’s effects remain.

5. What is the future of Ethereum? Ethereum’s future looks promising, with the shift to a Proof-of-Stake consensus mechanism through the Merge, which is expected to improve scalability and reduce energy consumption.
