7z was fastest AND smallest...

Just sayin'
 
I guess so vertoe :smile:
Thanks camosoul , interesting comparison. However I think I'll stick to zip as the most universal one for all OS-es (imo). :rolleyes:

You can make it self extrating exe if you want.
7zip is best compression software what you can get.

My starting point is - zip can be opened with no additional software on windows and mac. Linux users usually can take care of themselves and install zip (from official repo on ubuntu, for example) :)
 
Never mind, i believed its universal pakcage exe, its not.:oops:
 
How about good compression to blockchain transfer? -> SPEED?

We are talking about https://github.com/UdjinM6/darkcoin-bootstrap I guess... this has no connection with wallet sync by downloading blockchain except the one that wallet do not need to download blocks one by one and can grab most of them from bootstrap.dat and download only a small portion of blocks (at most for the last day as I'm making bootstrap once a day)

Yes we are, just asking, as we had discussion about this (blockchain compression) before...

I think there is no real need in additional compressing. Also we are going to move to bitcoin branch 0.10 ( vertoe is already on it) so we'll have "headers first" feature and sync should be blazingly fast anyway.

Ok, thats great, we will see when it is done.
 
UdjinM6, the bootstrap is great! It took me only about an hour to install v.11.1.25 the other day. It seems faster than before.

is this for UdjinM6 ?

It's for all who have micro-uplink. Every little bit helps on my suck pipes... Not telling Udjin to change anything cuz we know the winblows people will throw a shitfit if they have to actually know/do anything... Just wanted to let people know there's a significantly better choice if they need it. Would be nice if it was available in both and don't think it would be any harder to automate that than the current process, but it's not the end of the world.
