Ethereum is the second-largest cryptocurrency by market cap, featuring smart contract functionality and a proof-of-stake consensus mechanism. Learn its history.

Ethereum remains the second-largest cryptocurrency by market capitalization, trailing only Bitcoin, as it continues to function as a decentralized platform for smart contracts and decentralized applications [1, 2]. The network, which went live on 30 July 2015, has evolved from its proof-of-work origins to a proof-of-stake consensus mechanism, a transition completed on 15 September 2022 that reduced the blockchain's energy consumption by more than 99% [2].

| At a glance | |
|---|---|
| Market Position | Second largest cryptocurrency [2] |
| Launch Date | 30 July 2015 [2] |
| Consensus Mechanism | Proof-of-Stake (since 15 September 2022) [2] |
| Primary Utility | Smart contracts and decentralized applications [2] |

## Development and Technical Milestones
Proposed in late 2013 by Vitalik Buterin, Ethereum was designed to provide a more robust programming language for blockchain applications than what was available for Bitcoin at the time [1, 2]. The project was crowdfunded in 2014, with the network launching the following year with an initial supply of 72 million coins [1, 2]. Unlike Bitcoin, which is primarily used for monetary transactions, Ethereum’s architecture allows for smart contracts—small computer programs that automatically execute when specific conditions are met [1, 2].

The platform has faced significant historical challenges, including a 2016 split that resulted in the creation of Ethereum Classic and the infamous DAO hack, which saw approximately 3.6 million ether—roughly 15% of the total supply at the time—stolen [1]. Despite these events, the network has maintained its position as the primary hub for decentralized finance (DeFi), where users can borrow, lend, and deploy applications without relying on traditional financial intermediaries like banks or brokerages [2].

## Network Architecture
Ethereum’s current iteration, often referred to in the context of its ongoing upgrades, utilizes a blockchain that is open for public inspection [1]. This transparency is intended to protect the system against theft and unauthorized alterations, as the network of computers globally keeps a synchronized record of every transaction [1]. The native currency, ether (ETH), serves as the payment mechanism for these transactions and acts as compensation for the network participants who verify them [1].

| Metric | Detail |
|---|---|
| Initial Supply | 72 million coins [1] |
| DAO Hack Impact | ~3.6 million ether stolen (2016) [1] |
| Energy Reduction | >99% via "The Merge" [2] |

## What to watch
*   **Protocol Upgrades:** Monitor future developments regarding sharding, which aims to increase transaction throughput on the network [1].
*   **Regulatory Environment:** Observe how the platform navigates ongoing scrutiny, following historical incidents such as the 2019 arrest of an Ethereum Foundation employee regarding international conference appearances [1].
*   **Ecosystem Growth:** Track the deployment of new decentralized applications and the continued adoption of smart contract-based financial instruments [2].

The long-term significance of Ethereum lies in its transition from a simple currency network to a Turing-complete platform capable of hosting complex, immutable code. Whether the network can maintain its technical advantages while scaling remains the central question for its future development.
