What Is a Decentralized Network?

A decentralized network has no single company or server in charge. Control and data are spread across many participants. In cryptocurrency, the blockchain is maintained by many nodes around the world. No one can unilaterally change the rules or erase history without the rest of the network agreeing.

Why It Matters for Crypto

Decentralization is what allows crypto to work without a bank or government. No one can freeze your balance or reverse your transaction if the rules of the protocol are followed. The trade-off is that you are responsible for your keys and that upgrades require broad agreement.

Reality Check

Not every "crypto" project is fully decentralized. Some have influential developers or foundations. Exchanges and custodial wallets are centralized: they hold your keys. Understanding who controls what helps you assess risk and choose where to hold your assets.
