Ethereum
ETHA decentralized world computer enabling programmable smart contracts and decentralized applications.
Résumé exécutif
Ethereum est une plateforme open-source layer-1 blockchain platform proposed in 2013 by Vitalik Buterin and launched in 2015. It introduced contrats intelligents, allowing developers to build decentralized applications (dApps), financial protocols (DeFi), and digital tokens.
Fonctionnement & Architecture
EVM & Smart Contract Execution
The Ethereum Virtual Machine (EVM) acts as a global decentralized computer that executes code deterministicly across thousands of node validators.
Developers write contrats intelligents in languages like Solidity. Users pay a computation fee called "gas" (denominated in gwei) to execute transactions and state transitions.
Proof-of-Stake Consensus (The Merge)
In September 2022, Ethereum transitioned from Proof-of-Work to Proof-of-Stake (PoS) in an upgrade known as "The Merge".
Validators lock up (stake) 32 ETH to secure the network, reducing energy consumption by over 99.9% while introducing staking yield mechanics.

Avantages clés & Considéraitons
Avantages
- Largest developer ecosystem and smart contract network effect
- Environmentally sustainable Proof-of-Stake consensus
- Deflationary supply dynamics during high network activity (EIP-1559)
Inconvénients & Considérations
- Base layer congestion during peak usage leading to high gas fees
- Complex smart contract security risks and potential code exploits
- Increasing protocol state size requirements for node operators
Foire Aux Questions
Q: Qu'est-ce que le Ethereum Virtual Machine (EVM)?
The EVM is the execution environment for smart contracts on Ethereum, serving as the industry standard adopted by dozens of compatible layer-1 and layer-2 blockchains.
Q: What was "The Merge"?
The Merge was Ethereum’s historic upgrade in 2022 that successfully migrated the network from energy-intensive Proof-of-Work to Proof-of-Stake consensus.
