Ethereum (Ethereum) was initially designed as a smart contract platform (Platform for Smart Contract), enabling Turing-complete applications to execute autonomously based on predefined logic. Ideally, this eliminates issues like downtime, censorship, fraud, and third-party interference.
The Ethereum platform supports clients implemented in multiple programming languages, including Golang, C++, and Python. While its core design borrows from Bitcoin's blockchain principles, it extends functionality for broader applications.
The Ethereum team maintains a public blockchain network—Ethereum Network—where developers use Solidity (Ethereum’s native programming language) and official tools to build decentralized applications (DApps). These applications run on the Ethereum Virtual Machine (EVM), sustained by Ether (ETH) used to purchase Gas for computational resources.

History of Ethereum
Compared to Bitcoin’s 2009 launch, Ethereum is relatively young:
- 2013: Vitalik Buterin proposed a Turing-complete blockchain platform for arbitrary applications, diverging from Bitcoin’s limited scripting. This idea became the Ethereum whitepaper.
- 2014: Developers like Gavin Wood joined, initiating a crowdfunding campaign to build the platform.
- 2015: Frontier (Phase 1) launched with PoW consensus, similar to Bitcoin, targeting developers.
- 2016: Homestead (Phase 2) improved security and usability, attracting more users.
- 2017: Enterprise Ethereum Alliance (EEA) formed with members like J.P. Morgan and Microsoft.
- Future: Metropolis and Serenity will introduce PoS consensus and scalability solutions like sharding.
Key Features
Ethereum’s blockchain differs from Bitcoin with these technical highlights:
- Smart Contracts: Turing-complete via Solidity and EVM.
- ASIC-Resistant Hashing: Minimizes mining centralization.
- Uncle Blocks: Incentivizes faster block generation (~15s vs. Bitcoin’s 10m).
- Account Model: Uses world state, not UTXO, for complex logic.
- Gas Mechanism: Prevents infinite loops by metering computation.
- Consensus: PoW today; PoS planned for energy efficiency.

FAQ
Q: What is Gas in Ethereum?
A: Gas is a unit measuring computational effort. Users pay ETH to cover Gas costs for transactions/contracts.
Q: How does Ethereum achieve scalability?
A: Through planned upgrades like sharding, which parallelizes transaction processing.
Q: What’s the difference between Ether and Bitcoin?
A: Ether fuels Ethereum’s ecosystem (DApps, contracts), while Bitcoin is primarily a digital currency.
Conclusion
Ethereum’s flexibility and active development make it a leader in blockchain innovation. Its focus on decentralized applications and upcoming PoS transition positions it for long-term growth.
