Transaction processing requires a significant amount of computing resources. Users who join the network can allocate time to the computer to process the transaction. As a reward they receive the BCN. This process is called mining.
Pros
You can participate in network activity by allocating the computing power of your computer. Because of this mechanism, transaction processing is decentralized, allowing one to be not only a user but also a participant.
Cons
I think total BCN supply exceeded. 184,470,000,000 BCN
