What is Ethereum’s significance in the crypto ecosystem after its first decade?
Ethereum is the leading smart contract blockchain that has driven major innovations in decentralized finance (DeFi), non-fungible tokens (NFTs), and institutional investment products like ETFs. Its evolution from ICOs to proof-of-stake and layer-2 scaling solutions highlights its adaptability and central role in crypto’s growth.
How did the 2016 DAO hack influence Ethereum’s development?
The DAO hack exploited a vulnerability, resulting in a $60 million loss and a controversial hard fork. This split the community, creating Ethereum Classic while the main chain reversed the theft. This event established governance precedents and underscored security challenges in decentralized projects.
How did the ICO boom and NFT craze impact Ethereum’s network and price?
Between 2017 and 2018, Ethereum became the primary platform for ICOs due to the ERC-20 token standard, fueling a price surge to $1,450. Simultaneously, NFTs like CryptoKitties caused network congestion, highlighting scalability issues that persist today.
What role did DeFi summer play in Ethereum’s growth?
In 2019-2020, DeFi protocols such as MakerDAO and Uniswap leveraged Ethereum’s smart contracts to create decentralized financial services. This period saw total value locked surpass $1 billion, driving network usage and increasing ETH’s price above $750 by year-end 2020.
Why was the 2022 Merge upgrade critical for Ethereum?
The Merge transitioned Ethereum from energy-intensive proof-of-work to proof-of-stake, drastically reducing energy consumption and setting the stage for future scalability improvements. This upgrade was a milestone in Ethereum’s sustainability and institutional appeal.
How are Ethereum layer-2 solutions and ETFs shaping its 2024-2025 landscape?
Layer-2 rollups like Arbitrum and Optimism have improved transaction throughput and reduced fees, though liquidity fragmentation remains a challenge. Meanwhile, the launch of Ethereum-based ETFs in the US has reignited institutional interest, with ETH ETF inflows surpassing Bitcoin ETFs in mid-2025.

2015-2016: The birth of Ethereum and The DAO hack
Ethereum launched in 2015 as a groundbreaking smart contract platform. In 2016, The DAO project aimed to decentralize venture capital but suffered a $60 million exploit. The resulting hard fork reversed the theft, splitting the chain and creating Ethereum Classic, a defining moment for blockchain governance.
Ethereum’s history has been full of crazes, such as ICOs, NFTs and airdrops.
2017-2018: Ethereum explodes with the ICO boom
The ERC-20 token standard enabled a surge of ICOs, making Ethereum the preferred launchpad for new tokens. Ether’s price soared to $1,450 by early 2018. However, network congestion from NFT games like CryptoKitties exposed scalability issues, while regulatory scrutiny increased, leading to a market correction.
