Proposed by Vitalik Buterin in 2013 and launched in 2015, Ethereum introduced smart contracts to blockchain, enabling decentralized applications (dApps) beyond simple money transfers. Following a 2014 ICO, the network grew rapidly, despite the 2016 DAO hack leading to a split (Ethereum/Ethereum Classic). Key milestones include the 2022 Merge to Proof-of-Stake and upgrades enhancing scalability.
Key Historical Milestones
2013–2014: Conception & Funding: Vitalik Buterin published the Ethereum Whitepaper, proposing a programmable blockchain. Co-founders included Gavin Wood, who wrote the "Yellow Paper" EVM spec, and Charles Hoskinson. A 2014 crowdsale raised funds for the project.
2015: Launch: The network went live in July 2015, with the first transaction recorded in August.
2016: The DAO Hack & Fork: A decentralized investment fund (The DAO) was hacked. To recover funds, the network underwent a hard fork, creating Ethereum (ETH) and Ethereum Classic (ETC).
2017: ERC-20 & ICO Boom: The implementation of the ERC-20 standard simplified token creation, leading to a surge in Initial Coin Offerings (ICOs) and massive growth in ETH value.
2020: DeFi Summer: The rise of Decentralized Finance (DeFi) applications on Ethereum led to increased usage and high gas fees.
2022: The Merge (Proof-of-Stake): In September, Ethereum successfully transitioned from Proof-of-Work to Proof-of-Stake (PoS), reducing energy consumption by roughly 99%.
2024–2026: Scaling & Upgrades: The 2024 "Dencun" upgrade introduced proto-danksharding for lower transaction fees. By 2025-2026, the network shifted towards layer-2 scalability, though it faced market volatility and environmental scrutiny.
Key Historical Trends
Price Volatility: Ether (ETH) moved from under $1 in 2015 to nearly $5,000 by late 2021.
Utility: Ethereum is now the primary chain for NFTs and decentralized apps (dApps).
Governance: The network has proven adaptable through multiple forks to upgrade its security and functionality.
