Blockchain decentralization refers to distributing control and decision-making across a network, rather than relying on a single central authority. This is achieved through a network of computers, or nodes, that all have a copy of the entire blockchain.

Each node participates in validating transactions, which enhances security and transparency. By not depending on a central entity, the risk of fraud or manipulation is significantly reduced. If one node goes down, the network can continue to function normally, ensuring resilience.

Decentralization also promotes greater participation, as anyone can join the network and contribute. This democratic approach encourages innovation and collaboration among users, fostering a more inclusive ecosystem. In summary, blockchain decentralization promotes security, resilience, and inclusivity by distributing control and encouraging participation across many nodes in the network.
