Backtrace

In dev mode, the node only mines if there are transactions. Make a transaction and the node will mine it.

I know this is pretty old, but what can I do if I'd like to locally test code which relies on confirmations?

[karalabe]

You can force dev mode to seal blocks periodically instead of waiting for transactions via --dev.period=3 (for a 3 second period). You lose instant transactions though. Would that be enough?

@karalabe Is it possible to get the instant-block functionality via genesis.json instead of --dev? I have a genesis.json that is setup a certain way for our project, but I am using clique which appears to have a minimum of 1 second blocks. If I try to use --dev geth complains because the rest of my settings are not compatible with that mode.
