Minimum block creation rate


Is there any aproximate practical or architectural floor to the block creation rate ?

Having read “1.4.7 No Empty Blocks” at


It apears it is possible to set a ceiling. Eg,

create_empty_blocks = true; create_empty_interval = 10s

Says create an empty block every 10s if nothing has changed. Is there an reason to assume (roughly) at least some number of seconds will elapse between blocks ?
