Bitcoin's security comes from being
decentralized, meaning that many
different computers (nodes) in the
network check and agree on all
transactions independently. The rule of
"one CPU, one vote" ensures that power is
spread out across the network, making it
very hard for any one group to take control
or attack it. As long as most of the
computing power belongs to honest
participants, the network is safe from
anyone trying to change the blockchain
