Blockchain decentralization refers to the distribution of power and control across a network of nodes, rather than being concentrated in a single central authority. In a decentralized blockchain network, no single entity has the authority to control or manipulate the system, and all participants have equal access and rights.

Overall, blockchain decentralization is a fundamental principle that underpins the trustworthiness and resilience of blockchain networks, making them suitable for a wide range of applications beyond just cryptocurrencies.
