multi chain keeps generating blocks

Question

I've just created a multichain with the default parameters :

$ multichain-util create dockerchain

then I started the multichain master node

$ multichaind -shrinkdebugfilesize -printtoconsole docker chain

and I waited. just to make clear : i've done nothing.

after a while, I realized that it keeps generating blocks.

why ? can you help me ?

here is the log :

Answer 1

This is currently the intended behavior - blocks are created at approximately the desired interval, even if there are no new transactions. We may add an option in future to pause block generation if there are no new transactions.
