History of Ethereum to The Merge

History of Ethereum from inception to The Merge

The birth of Ethereum in 2015 marked a significant milestone in the world of cryptocurrencies. Whilst not the first or even second cryptocurrency to be invented, Ethereum, created by Vitalik Buterin, introduced the concept of smart contracts and decentralized applications (DApps), revolutionising the way we think about blockchain technology.

The Inception of Ethereum

The Vision of Vitalik Buterin and the Concept of Ethereum

In 2013, Vitalik Buterin, a programmer and co-founder of Bitcoin Magazine, published the Ethereum Whitepaper, outlining his vision for a decentralised platform that enables the development of smart contracts and DApps. Buterin aimed to create a platform that goes beyond the capabilities of Bitcoin, allowing for the execution of complex programmable transactions.

The Ethereum Whitepaper and the Early Development Stages

The Ethereum Whitepaper introduced the concept of a blockchain platform that utilises a Turing-complete programming language to enable the execution of smart contracts. Buterin’s proposal gained attention and support from the cryptocurrency community, leading to the formation of the Ethereum Foundation and the commencement of development work.

The Launch of Ethereum

The Initial Coin Offering (ICO) and the Distribution of Ether (ETH)

To fund the development of Ethereum, an ICO was conducted in 2014. Participants could purchase Ether (ETH) tokens, which would serve as the native cryptocurrency of the Ethereum platform.

The ICO raised approximately $18 million, providing the necessary resources to launch the network.

The Challenges and Controversies Faced During the Launch

The launch of Ethereum in 2015 was not without its challenges. The network experienced technical difficulties and faced security vulnerabilities, leading to delays and concerns among early adopters. However, the Ethereum team worked diligently to address these issues and ensure the successful launch of the platform.

The Evolution of Ethereum

Key Protocol Changes and Upgrades Throughout Ethereum’s History

Since its launch, Ethereum has undergone several protocol changes and upgrades to enhance its functionality and address scalability issues. These upgrades include the introduction of the Homestead release, which marked the transition from the Frontier phase to a more stable and mature platform.

Subsequent upgrades, such as Byzantium, Constantinople, and Istanbul, introduced improvements to security, efficiency, and network resilience.

The Role of Miners in the Ethereum Network

Until 2022, Ethereum was closely intertwined with crypto mining. Often equipped with specialised GPU mining rigs, miners played a crucial role in the Ethereum network by validating transactions and securing the blockchain. 

Ethereum utilised a proof-of-work (PoW) consensus mechanism, similar to Bitcoin throughout its history. However, with the Ethereum 2.0 upgrade in 2022, the network transitioned to a proof-of-stake (PoS) consensus mechanism, where validators are selected based on the amount of cryptocurrency they hold and are willing to stake.

The Impact of Hard Forks and the Creation of Ethereum Classic

In 2016, Ethereum faced a significant controversy known as the DAO hack, where millions of dollars worth of Ether were stolen due to a vulnerability in a smart contract.

To rectify the situation, the Ethereum community decided to perform a hard fork, creating a new version of the blockchain that reversed the hack. However, a portion of the community chose to stick with the original blockchain, leading to the creation of Ethereum Classic (ETC).

The Introduction of the Beacon Chain and the Transition to Proof-of-Stake

The Beacon Chain, launched in December 2020, represented a major milestone in the transition to Ethereum 2.0. It served as the backbone of the new Ethereum network, transitioning from PoW to the PoS consensus mechanism and paving the way for improved scalability and security. The Beacon Chain, followed by subsequent phases, including The Merge, Shard Chains, and Docking, all aim to further enhance the capabilities of the Ethereum network.

Unlike Ethereum, it’s worth noting that Ethereum Classic (ETC), which was created from the DAO hard fork, has remained PoW and continues to be mineable by GPUs. To this day, PoW is its key differentiator, advertising itself as the original, immutable, decentralised proof-of-work Ethereum. We’ll cover this Ethereum Classic, along with more recent forks like Ethereum Fair (ETHF) and Etherem PoW (ETHW), in our upcoming articles.

The Phases of Ethereum 2.0 and Their Objectives

Ethereum 2.0 is being implemented in multiple phases, each focusing on specific objectives.

The initial phase, known as Phase 0 in 2020, introduced the Beacon Chain and the proof-of-stake consensus mechanism. Subsequent phases such as The Merge in 2022 and sharding expected to happen in 2024 will allow for parallel processing of transactions and smart contracts, significantly increasing the scalability of the network.

The final phase, known as Phase 2, will integrate all the components of Ethereum 2.0 and complete the transition from the current Ethereum network.

Ethereum’s Impact on the Crypto Landscape

The Rise of Decentralised Apps and Smart Contracts

Ethereum’s introduction of smart contracts and DApps has revolutionized the blockchain landscape.

Smart contracts enable the execution of self-executing agreements without the need for intermediaries, while DApps allow developers to build decentralised applications on the Ethereum platform.

This has opened up new possibilities for various industries, including finance, supply chain management, and digital art.

The Role of Ethereum in the Growth of Decentralised Finance (DeFi)

Decentralised finance, or DeFi, has gained significant traction in recent years, and Ethereum has played a crucial role in its growth.

DeFi applications built on the Ethereum blockchain allow for various financial services, such as lending, borrowing, and trading, without the need for traditional intermediaries.

Ethereum’s programmability and flexibility have made it the platform of choice for many DeFi projects, contributing to the exponential growth of the DeFi ecosystem.


Hopefully, this article in our series on Ethereum has provided a useful overview of the history of Ethereum and its timeline from a visionary concept to a mature and influential blockchain platform.

From its inception to the Ethereum 2.0 upgrade, Ethereum has continuously evolved, addressing scalability issues and paving the way for the future of blockchain technology. With its impact on decentralised apps, smart contracts, and the growth of DeFi, Ethereum has solidified its position as a leading player in the cryptocurrency ecosystem.

As Ethereum 2.0 unfolds, the future looks promising, with enhanced scalability, security, and sustainability on the horizon.
