Ethereum's journey began over a decade ago, born from the vision of its founder, Vitalik Buterin. A gifted mathematician, Buterin grew frustrated with Bitcoin's limitations and believed blockchain technology could achieve far more. His idea was to transform cryptocurrency from a simple monetary asset into a "world computer"—a platform hosting decentralized applications powered by smart contracts, operating with minimal human intervention or trust assumptions.
Today, Ethereum stands as the world’s second-largest cryptocurrency, supporting an ecosystem worth trillions of dollars. It is the blockchain of choice for major asset management firms and serves millions of daily users directly and via Layer 2 networks.
Here are the 11 most critical moments in Ethereum’s history, along with a glimpse into its future upgrades.
Early Vision and Foundation
Buterin first discovered Bitcoin through his father, a Russian-born engineer who later moved the family to Canada. Lacking funds to invest in Bitcoin mining or the asset itself, Buterin began writing for crypto blogs in the early 2010s, earning payments in BTC.
His talent caught the attention of Mihai Alisie, a Romanian Bitcoin enthusiast. Together, they launched Bitcoin Magazine in 2012. A year later, at just 19 years old, Buterin published the Ethereum whitepaper, which described a "next-generation smart contract and decentralized application platform."
He later explained his motivation simply: he wanted to fix Bitcoin’s narrow functionality. He compared Bitcoin to a pocket calculator—excellent at one thing—while Ethereum would be like a smartphone, capable of supporting countless applications.
Buterin received a $100,000 Thiel Fellowship grant to develop the Ethereum platform.
The Infamous “Red Wedding”
Before Ethereum became what it is today, it faced internal conflict. The first major rupture came during what became known as the "Red Wedding."
On June 7, 2014, the founding team gathered in Zug, Switzerland, to sign documents turning Ethereum into a for-profit company. However, tensions over management style, project contributions, and future direction reached a boiling point.
Buterin was left to decide Ethereum’s path. He removed Charles Hoskinson (who later founded Cardano) and Amir Chetrit from the project and established Ethereum as a non-profit foundation instead of a company.
As co-founder Joe Lubin recalled in a 2023 interview, "We had differences of opinion. Sometimes, those differences became very intense—even infamous."
The Initial Coin Offering (ICO)
Ethereum’s next major step was its Initial Coin Offering (ICO) in 2014, which raised funds and drew significant public attention. From July 22 to September 2, investors purchased over $18 million worth of ETH, paid in Bitcoin.
The Ethereum blockchain and its native token, ETH, officially launched on July 30, 2015. At launch, ETH was valued at $0.31. Those who held until today’s price of around $3,275 would have seen a life-changing return.
It is rumored that Joe Lubin, co-founder of Ethereum and Consensys, was the largest investor in the ICO.
The DAO Hack and Aftermath
Perhaps the most impactful event in Ethereum’s history was the notorious DAO hack, where an attacker stole over 3.6 million ETH from an early decentralized autonomous organization.
The attack sent shockwaves through the market, causing ETH’s price to plummet from $20 to under $9 in less than 36 hours.
The community split into two camps: one wanted to continue without intervention, adhering to "code is law," while the other supported a network rollback to recover the stolen funds. This philosophical divide asked whether a blockchain should be immutable or subject to change to correct injustices.
Ultimately, the majority voted for a hard fork to roll back the blockchain. This resulted in two chains: Ethereum (the forked version) and Ethereum Classic (the original chain, which remains proof-of-work).
CryptoKitties and Network Congestion
One of the strangest yet most influential events was the rise of CryptoKitties, an NFT collection that nearly broke the Ethereum network.
Launched in October 2017 by Vancouver-based Axiom Zen, CryptoKitties allowed users to collect and breed digital cats. By December, it had gone viral, with some NFTs selling for over $170,000. The surge in activity clogged the network, causing transaction fees to skyrocket.
In response, developers from projects like MetaMask and Infura joined forces to optimize the network and work on long-term scaling solutions. While opinions on CryptoKitties remain mixed, its impact on Ethereum’s development and the broader NFT trend is undeniable.
The DeFi Summer of 2020
The summer of 2020, known in crypto circles as "DeFi Summer," marked a turning point. Ethereum suddenly became the breeding ground for a new kind of financial activity.
New users flooded the network, eager to experiment with hundreds of new protocols. This led to a boom in digital asset lending and trading, much of it driven by "yield farmers" earning token rewards.
Major DeFi protocols like Aave and Compound emerged during this period, now handling billions of dollars in daily volume. The era also saw the rise of "vampire attacks," where projects like SushiSwap forked existing protocols to attract users and liquidity.
The Pivot to a Rollup-Centric Roadmap
One of Ethereum’s strengths is its adaptable roadmap. In October 2020, Buterin abandoned the long-standing Eth 2.0 plan, which relied on sharding, in favor of a rollup-centric approach.
This shift was driven by the emergence of Layer 2 scaling solutions like Optimistic and ZK-rollups, which handle execution off-chain while relying on Ethereum for security.
Buterin explained that new technical discoveries, such as data availability sampling and advanced rollup designs, made this new direction possible. This pivot established Ethereum as the foundational layer, with scaling efforts focused on L2 networks like Polygon, Optimism, and Arbitrum.
The Merge: Transition to Proof-of-Stake
According to Ethereum developer Marius van der Wijden, the Merge was the "most critical" moment in the network’s history.
Completed on September 15, 2022, the Merge transitioned Ethereum from energy-intensive proof-of-work to the eco-friendlier proof-of-stake consensus mechanism.
This upgrade reduced Ethereum’s energy consumption by 99% and introduced significant changes to token economics. Van der Wijden expressed pride in the collective effort, highlighting the environmental benefits and reduction in electronic waste.
The Dencun Upgrade and Proto-Danksharding
The next major step occurred on March 13, 2024, with the Dencun upgrade. This introduced nine Ethereum Improvement Proposals (EIPs), most notably EIP-4844, which implemented proto-danksharding.
This innovation uses "blobs" to store transaction data separately and temporarily, dramatically reducing the cost of data availability on Layer 2 networks. As a result, transactions on chains like Arbitrum and Optimism became much cheaper.
A side effect, however, was a reduction in the amount of ETH burned in fees on the mainnet.
BlackRock’s Tokenized Fund on Ethereum
One of Ethereum’s biggest institutional milestones came on March 20, 2024, when asset management giant BlackRock launched a tokenized fund on the network.
The BlackRock USD Institutional Digital Liquidity Fund (BUIDL) is backed by cash and U.S. Treasury bills, offering daily yields to token holders. This move was seen as a major endorsement of Ethereum’s reliability and credibility.
As of recent data, the BUIDL fund has a market cap of over $517 million, with monthly trading volume exceeding $116 million.
BlackRock CEO Larry Fink, once a skeptic, now views cryptocurrencies like ETH and Bitcoin as an emerging asset class. "Over the past two years, I’ve become a big believer in ETH," he told CNBC.
Spot Ethereum ETF Approvals
On May 23, 2024, the U.S. Securities and Exchange Commission (SEC) approved nine spot Ethereum ETFs, which began trading on July 23.
This marked a significant step toward institutional adoption of ETH. Similar to Bitcoin ETFs, the launch saw outflows from Grayscale’s converted fund (ETHE) due to its high fees compared to competitors.
Despite initial net outflows of $390 million, flows are stabilizing. Nate Geraci, president of ETF Store, noted that BlackRock’s ETHA ETF had strong inflows, making it one of the year’s most successful launches.
