hmm.. pardon me , I'm very confused. Do you have videos or pictures to show? I try to find on internet but apparently most of them are so difficult for me to understand..
This site demonstrates how blockchain works visually (with videos), maybe it will be easier for you to understand how the blocks issue works.
https://anders.com/blockchain/I've seen before with this. Maybe can you explain in Ethereum form? let's say the average block time are 10 ~ 13 seconds. per confirmation will be 10 ~ 13 seconds as well right?
