Explanation: It takes about 10 minutes for miners to find a nonce that solves the PoW puzzle in Bitcoin. When the number of nodes reduces, so does the hashing power of the network, and this interval increases when the nodes increase so does the network hashing power and blocks get mined faster, a retargeting algorithm is used to maintain this interval to 10 minutes.
