How Does Decentralization Mitigate the Risk of a 51% Attack?

Decentralization means that the network's power is distributed across many independent nodes or validators globally. The more decentralized the network, the harder and more expensive it is for a single entity to coordinate and acquire 51% of the necessary resources (hashing power or staked capital).

This distribution of control ensures no single point of failure exists, making the attack logistically and financially improbable.
