I have a private blockchain. Even though there is not much transactions going on, the chain's size keep increases. I observe that if there is not any transaction occurs still blockchain size increases, please note that I am not 100% sure.
For example, a block-chain started and there is no transaction occur for a week. In this time does the blockchain's size still get increases? If yes, what might be the reason, since state of the blockchain does not change at all.
Thank you for your valuable time and help.
