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?
Once your transaction is included in a block and it is mined, yes, every 10 ~ 13 seconds (on average) your transaction will receive a confirmation because this is the average mining time of 2 ethereum blocks.
