What is broadcast transaction - mempool - bitcoin explorer?
Could you elaborate on the concept of "broadcast transaction - mempool - Bitcoin explorer" in the context of cryptocurrency? Specifically, I'm interested in understanding how a transaction is broadcasted onto the Bitcoin network, how it enters the mempool, and how a Bitcoin explorer can be used to track and analyze these transactions. What are the key steps involved in the process? Additionally, how does the mempool work and what factors determine whether a transaction is prioritized for inclusion in a block? Lastly, how can a Bitcoin explorer provide valuable insights into the transaction lifecycle and the state of the network?
