What Is the Concept of ‘Decentralization’ in Preventing Network Attacks?

Decentralization refers to distributing control and decision-making away from a central point to multiple participants across a network. In cryptocurrency, a highly decentralized network is more resilient to attacks because an attacker would need to compromise a majority of the numerous, independent nodes or participants.

This high barrier to control makes coordinating a 51 percent attack significantly more difficult and expensive, thus enhancing network security.
