Introduction
During last year's crypto bull run, Ethereum's price surged over 100x from its initial sub-$10 valuation. At its peak, Ethereum accounted for 32% of the total cryptocurrency market capitalization, compared to Bitcoin's 39% dominance. Many analysts credit Ethereum as the primary driver of the 2024 crypto market boom.
Ethereum is an open-source, blockchain-based platform featuring smart contract functionality12. Its native cryptocurrency, Ether (ETH), powers a decentralized virtual machine (Ethereum Virtual Machine) that executes peer-to-peer contracts.
Ethereum's Four Development Phases
The platform's evolution is structured across four major stages:
- Frontier (2015) - Initial testnet launch
- Homestead (2016) - First stable production release
- Metropolis (2017-2019) - Enhanced functionality
- Serenity (Upcoming) - Transition to Proof-of-Stake (PoS)
The first three phases utilize Proof-of-Work (PoW) consensus, while Serenity will implement PoS.
Ethereum's Historical Timeline

FAQ
What makes Ethereum different from Bitcoin?
While Bitcoin operates as digital gold, Ethereum functions as a programmable blockchain that supports smart contracts and decentralized applications.
How does Proof-of-Stake improve Ethereum?
PoS replaces energy-intensive mining with staking, reducing Ethereum's energy consumption by ~99% while improving scalability.
What was "The DAO" incident?
A 2016 smart contract exploit that led to Ethereum's first major hard fork, creating Ethereum Classic as the original chain continued.
When will Ethereum 2.0 launch?
The full Serenity upgrade is being implemented gradually, with key components like sharding expected by 2025.
