ZmnSCPxj,
No, it would be better to use parachains for Mars.

What?<br>
<br>
That is surprising information to me.<br>
<br>
My understanding is that speeding up block creation times is highly risky d=

"PoS" networks mean nothing, as most of them are not global in th=

Changing inter-block times is not possible as a softfork, unless you are pl=
