Network
Technical infrastructure enabling the validation and security of transactions.
Beginner-friendly explanation
A network in crypto is a group of computers connected to manage and validate transactions. Each computer, called a node, helps secure the system.
๐ Example: When you send bitcoins, they pass through the Bitcoin network which validates your transaction.
Intermediate-level insight
A blockchain network relies on a consensus protocol (Proof of Work, Proof of Stake, etc.) to synchronize data between nodes. Decentralization, redundancy, and fault tolerance are key characteristics.
๐ Example: The Ethereum network now uses Proof of Stake to validate its blocks and secure transactions.
Advanced perspective
A networkโs robustness depends on its topology quality, the geographical distribution of nodes, resilience against Sybil or DDoS attacks, and the governance of protocol updates. A secure network promotes trust and asset sustainability.
๐ Example: Bitcoin maintains its security thanks to a very large number of independent nodes worldwide, making any network attack extremely difficult.
