As you know, the number of confirmations in bitcoin transactions have a direct effect on transaction speed. A transaction with 3 confirmations will be processed faster than the one with 6 confirmations. The process of confirmation is approved by any computer which is on the blockchain network. So, we have a network with a lot of computers and miners but not all of them are always online to confirm transactions.
What I want to know is that whether the number of online computers on the network can affect bitcoin transaction speed or not? Does bitcoin transaction speed increase if there are more online computers on the network? Does it mean that bitcoin transaction speed will improve in the future when the number of computers on blockchain network increase?
