Currently the block time among blocks is 20 seconds in average, how can reduce this 20 seconds parameter?
I know there are disadvantages when reduce the block time to 5 seconds or less, my intention is reduce to 10 or 12 seconds.
In private Ethereum blockchains it was possible to change the block time, changing the CalculateDifficult function, but since Quorum has changed to Voting-consensus the difficult has no impact in the block time.
Finally, I figured out how to change it
according to the help, there are two arguments for geth command line:
geth --help
--minblocktime value Set minimum block time (default: 3)
--maxblocktime value Set max block time (default: 10)
the values are in seconds.
