Hi Jim,

I'm running Multibit 0.5.18 and I have several wallets

Everytime I open a different one, Multibit syncs it back since March 25th, 2014.

This is not only becoming annoying, but makes using a wallet increasingly slower.

Can you make a new multibit.checkpoints file? Or is there a method to build one?

Regards.

Great question!  This might solve a long-standing issue for me, too.  I've never liked keeping my main wallet open when I shut down the program.  I like closing the wallet, then the program.  That seems safer to me.  But then, when I restart the program (and wait for it to sync) then re-open the wallet, it has to re-sync all over again from about March, like you say -- and that takes forever when you're waiting to do a transaction.  I've been told, "Just leave the wallet open when you close the program."  And now I do that.  But I'm still not comfortable with it.

I don't think there is any problem leaving them open, when you close MultiBit, it closes every open wallet before shutting itself down.

The issue remains though and in my case  is compound by the fact the I can't have all of them open at the same time or otherwise sync never ends, it keeps resending bloom filters over and over again and it take 30-40 seconds each time it has to recalc them!

If your able to build bitcoinj from source you can generate your own checkpoint files and then just replace the existing checkpoint file in multibit's datadir.

I just generated a new one now

Code:
Synchronising with network, 6,053 block(s) to download. Block date : "19/11/2014"

Thank you esotericizm,

I'll test it in the coming days.

Happy New Year!

Does it mean that by using your multibit.checkpoints file, when I do "Reset blockchain" it only goes as far as 19/11/2014 ? Thanks.

Yeah mate thats what it should do. If it works leave a post here.

I'm not sure how far away multibit-hd is but I'd be happy to keep a semi updated checkpoint file available for the guys that want it.

After chaning the file and hitting the Reset, multbit started to load all blocks since my first transaction (Dec 2013). It doesnt appear to help :-(

It works when you have multiple wallets, you open one, sync it, close it and then open a second one, at this point MultiBit syncs this second wallet from the time its checkpoints file was made.

Thanks to esotericizm it now syncs from november 19th last year, so it is a lot faster!
