What is Decentralization?
The short answer
Spreading control across many independent participants instead of one company, so no single party can change the rules alone.
Most services you use are run by one company. That company owns the servers, holds the records, and can change the rules, freeze an account, or shut the service down. That is a centralised system, and for most things it works fine.
A decentralised system spreads that control across many independent participants instead. No single one of them holds the only copy of the records, and no single one can unilaterally rewrite them or lock someone out. Bitcoin works this way: thousands of computers each keep the same ledger and check each other’s work.
Decentralization is a spectrum, not a switch. Plenty of things described as decentralised in crypto marketing are run by a small group in practice — it is worth asking who actually controls a project before taking the label at face value.
