I apologize for any confusion my quote may have caused. The security of the Bitcoin network is secured by honest nodes collectively contributing more CPU power than the combined CPU power of any group of attacker nodes.

While energy consumption is a naturally occurring aspect of the process, it is not the determining factor in the network's security. The CPU power represents the amount of computational work required to maintain the network, as well as the ability to protect it against malicious attacks.

In summary, the Bitcoin network's security is maintained through the collective power of honest nodes who contribute computational work, which is then used to validate transactions and secure the network against attackers.
