Here are 10 moments that defined Ethereum’s decade of disruption

On July 30, 2015, Ethereum launched, sparking a blockchain revolution. Founded by Vitalik Buterin, this platform introduced smart contracts, enabling the creation of programmable, decentralised applications. From a $0.31 ICO price to nearly $4,000 today, ETH’s meteoric rise reflects its transformative impact. 

Earlier in April, ETH, the world’s second-largest crypto by market capitalisation, overtook Chinese e-commerce giant Alibaba Group Holding Limited (BABA) to become the 32nd most valuable asset or company globally.

As it celebrates its 10th anniversary, we spotlight 10 defining milestones that made Ethereum the cornerstone of DeFi, NFTs, and Web3 in this article:

1. Genesis Block: Ethereum’s birth

Ethereum’s journey began with its genesis block on July 30, 2015. Vitalik Buterin, alongside co-founders Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin, launched the network after an $18.3 million ICO.

Priced at $0.31 per ETH, the crowdsale funded the “Frontier” release. This introduced the Ethereum Virtual Machine (EVM), enabling developers to build smart contracts. Its focus on programmability sets it apart from Bitcoin’s transaction-focused model.

2. ERC-20 standard: Powering the ICO boom

The ERC-20 token standard, proposed by Fabian Vogelsteller in November 2015, transformed Ethereum. It standardised fungible token creation, enabling interoperability across dApps.

This fuelled the 2017 ICO boom, with projects raising billions. ERC-20 tokens became the backbone of DeFi and token economies. Today, thousands of tokens, including USDT and LINK, rely on this standard.

3. The DAO hack: A turning point

On June 17th 2016, Ethereum faced a defining crisis. The DAO, a decentralised venture fund, raised $150 million but was hacked due to a smart contract flaw.

Attackers syphoned 3.6 million ETH, crashing ETH’s price from $20 to $9. The community’s response, a hard fork to recover funds, split the blockchain into Ethereum (ETH) and Ethereum Classic (ETC). This event exposed smart contract risks and shaped ETH’s governance.

4. CryptoKitties: Birth of NFTs

In November 2017, CryptoKitties introduced non-fungible tokens (NFTs). This game lets users buy, breed, and trade unique digital cats, clogging Ethereum’s network at its peak. The ERC-721 standard, created for CryptoKitties, defined NFTs, enabling digital collectables.

By 2021, NFTs had experienced a surge in popularity, with notable sales like Beeple’s $69 million artwork. CryptoKitties showcased its potential beyond finance.

5. DeFi explosion: Redefining finance

ETH became the hub of decentralised finance (DeFi) in 2020–2021. Platforms like Uniswap, MakerDAO, and Compound offered lending, borrowing, and trading without intermediaries

By 2021, DeFi protocols locked over $100 billion in value. Uniswap’s automated market maker (AMM), launched in 2018, revolutionised trading. MakerDAO’s DAI stablecoin provided stability. DeFi cemented ETH’s role in financial innovation.

6. EIP-1559: Fee market overhaul

The London hard fork on August 5, 2021, introduced EIP-1559. This upgrade revamped Ethereum’s transaction fee system, implementing a base fee burned with each transaction. An optional tip rewarded miners

EIP-1559 made fees more predictable and reduced ETH’s supply, creating deflationary pressure. This milestone improved user experience and aligned ETH’s economics with its growth.

7. The Merge: Going green

On September 15, 2022, Ethereum completed The Merge. This transitioned the network from proof-of-work (PoW) to proof-of-stake (PoS), cutting energy use by 99.99%.

Validators now secure the network by staking ETH, replacing energy-intensive mining. The Merge enhanced scalability and sustainability, positioning the blockchain as an eco-friendly leader.

8. Dencun Upgrade: Scaling with Blobs

The Dencun upgrade, launched on March 13, 2024, introduced EIP-4844 (proto-danksharding). It used “blobs” to store transaction data temporarily, reducing costs for layer-2 networks like Arbitrum and Optimism.

Dencun slashed L2 transaction fees, boosting Ethereum’s scalability. This upgrade strengthened its layer-2 ecosystem, which is critical for handling high transaction volumes.

9. BlackRock’s BUIDL Fund: Institutional trust

On March 20, 2024, BlackRock launched its BUIDL fund on Ethereum. This tokenised fund, backed by U.S. Treasury bills, reached a $517 million market cap. BUIDL signalled institutional confidence in ETH’s infrastructure.

It marked its evolution from a niche project to a trusted platform for traditional finance.

10. Pectra Upgrade: Staking and usability

In May 2025, the Pectra upgrade enhanced Ethereum’s functionality. EIP-7251 raised the staking limit from 32 ETH to 2,048 ETH, improving capital efficiency.

EIP-6110 cut validator activation time from 12 hours to 13 minutes. EIP-7702 allowed externally owned accounts to use smart contract features. Pectra made the blockchain more accessible and scalable.

Ethereum price journey: From $13 to $3,793.47

Ethereum’s price trajectory mirrors its technological leaps. In January 2016, ETH traded at $13, driven by early developer enthusiasm.

By November 2021, it hit an all-time high of $4,891.70, fuelled by DeFi and NFT booms. Despite dipping to $1,387 in 2025 amid market volatility, ETH recovered to $3,793.47 by July 30, 2025, reflecting institutional adoption and upgrades. This growth underscores its market resilience.

Its roadmap promises more innovation. The Prague-Electra upgrade, planned for late 2025, will introduce Verkle Trees, enhancing data efficiency. These upgrades aim to boost scalability and user experience.

With a $458.7 billion market cap, Ethereum dominates DeFi and NFTs, driving Web3’s growth.

Ethereum’s 10 years reshaped blockchain. Smart contracts, DeFi, and NFTs highlight its versatility. Upgrades like The Merge and Dencun showcase technical innovation. BlackRock’s BUIDL fund underscores institutional trust.

Despite challenges, ETH's adaptability ensures its leadership. As it enters its second decade, Ethereum continues to redefine technology and finance.
