Decentralisation.
Decentralisation means that no single person or company controls the system. Instead, control is spread across many participants.
Quick Reference:
Power is Distributed. No Central Bank. Transparent. Slower Decisions.
Expanded Explanation:
In traditional finance, banks or governemnts control the system. In crypto, decentralisation means thousands of independaent computres share responsibility. This makes the system harder to censor, more secure against single points of faily and open to anyone in the world. Decentralisation is a core principle of crypto, but it also comes with trade offs. It can make upgraes slower and coordination harder, compared to a central authority making quick decisions.
