Decentralization

Decentralization is the spreading of control and decision-making across many independent participants instead of concentrating it in one company, server or person. It is a core design goal of most cryptocurrencies.

How it works

A decentralized network distributes several things at once: the data (every node keeps a copy of the ledger), the validation (many independent miners or validators confirm transactions), and often the governance (token holders vote on changes). The more widely these are spread, and the harder they are to capture, the more decentralized the system is said to be.

Why it matters

Decentralization is what makes a network resistant to censorship, single points of failure and unilateral control — no one party can freeze funds or rewrite the rules alone. It usually comes at a cost in speed and coordination, which is the central trade-off every blockchain must balance.

Example

A network run by thousands of independent nodes worldwide is far more decentralized than one whose ledger sits on a handful of company servers.
