Network (Réseaux & Blockchains)
Set of interconnected computers running a blockchain.
Beginner-friendly explanation
A blockchain network is a group of computers (nodes) connected together to share and validate information in a decentralized way, without a central server. Example: Bitcoin is a global network with thousands of interconnected computers.
Intermediate-level insight
Each blockchain network follows its own consensus rules (Proof of Work, Proof of Stake, etc.) to validate transactions. A larger and more diverse network is more robust. Example: Ethereum network uses Proof of Stake to secure transactions since The Merge.
Advanced perspective
A blockchain network may include various participants (validators, miners, users, developers) and multiple communication layers (peer-to-peer, block propagation, state synchronization). Interoperability between networks is a major challenge for the Web3 ecosystem. Example: The Polkadot project builds an interconnected ecosystem of specialized blockchains called parachains.
