Is there a blockchain source?, I'm having trouble downloading via the qt wallet.
I've just spent 3 days downloading and it has corrupted at 80% (again) maybe due to windows vista 32bit?

Make your life easier by using the bootstrap link from http://www.mintcoinofficial.com/ Wink

Sent! Happy Testing Smiley

Received. Will do some more testing transactions.

Works like a charm. No issues so far. Running on Win 8.1.

Running the giveaway wallet on the wallet with no issues - sending / receiving / creating new address / etc...

As soon as we get the green light from SupaSonic for testing we should be able to release to the exchanges.

A big thanks to PressTab for this upgrade.

When using this bootstrap, better do not recycle an existing MintCoin data folder, only keep your old wallet.dat.
plus some step-wise instructions like yours above.

This sentence exists already in the READ_ME.txt:

… any ideas?
I had the same problem with mine on OSX , here's a quote of how to solve …
...
rename your MintCoin folder in %Application Data% and
let the MintCoin app create a new one ,
then quit ,
drop your blockchain & wallet.dat file into the new one and
start MintCoin again

Thanks, mommy ;-)
Done, and works. Beautiful, kudos. Syncing as we speak; that will take a while.

You caught be before going into work Smiley Make sure to report any issues and let is fully sync a new wallet for the testing purposes. Once you get the wallet up and running let me know your mintcoin addy so i can send you a few testing coins.

I had the same problem with mine on OSX , here's a quote of how to solve … if you have the blockchain just rename your MintCoin folder in %Application Data% and let the MintCoin app create a new one , then quit , drop your blockchain & wallet.dat file into the new one and start MintCoin again , it should be almost synched
to the last , taking only some minutes to get fully updated again …

I fixed some days ago my somehow corrupted and completely non working wallet on MAC OSX by downloading the latest version again ;
backup your wallet.dat , it is in /Users/»Your Username«/Library/Application Support/MintCoin/ before you fiddle around .

  • I renamed my MintCoin Folder appending to its name anything ,
  • installed the latest wallet app version anew , started it up ,
    and quit it while it was starting to resynch the blockchain from scratch .
  • At that point , the MintCoin Folder was recreated anew and I only had to
    drop the contents in Bootstrap.dat into that fresh MintCoin Folder …
    - it took the Wallet only a few minutes to synch up fully to the last few transactions on the public blockchain .
  • Lastly , drop the latest backup of your wallet.dat into the new MintCoin folder and you are good to Ball .


I don't think it is blockchain related but some db file gets corrupted as the error message indicates ; it should be possible to reuse a recently
downloaded or actualised blockchain that worked again . Maybe someone can clarify where the error occurs and hopefully fix the annoyance .

Perhaps it wasn't fully synced/downloaded ?
But it wasn't showing a "percentage left" anymore.

And then the sha1sum should differ, right?

Anyways for my next attempt, I'd rather choose a file that stays online longer. Now it is already 5/7/2015. And I'd rather not download a new 1.3GB again.
In the batch file, there is a mentioning of a "weekly update". What is the getsync address of that?
Or doesn't all that matter? New to getsync, sorry.

Thanks for the help!

happens with (unpacked)
  blockchain_2015_07_04.7z-backup
with
  mintcoin-qt.exe version 1.17


sha1sum blockchain_2015_07_04.7z-backup  
  was correct, resulted in 2316bc253800738abcd8f12aa2f045708c90b05b

any ideas?

If my assumptions are correct it will have no impact on RAM or on CPU.

Although it hashes the first 60 hashes * the amount of mature unspent outputs you have, those hashes are all destroyed the second the code leaves the scope of CheckKernelStakeHash(), as this is how c++ works.

The current code hashes the first 60 seconds, then hashes timestamp 61 after one second passes, then 62 after two seconds pass, etc. Not 60 hashes each time (or else if it is doing so, it is not designed to be this way).

MINT has a very very old codebase, that hasn't been updated much in terms of efficiency, as well as a huge blockchain. The pool of unspent outputs for the entire network is stored in your RAM, thus this means a large amount of ram for an old chain with lost coins or lots of cold storage outputs. The CPU usage is probably a combination of all these items.
What do you recommend to improve efficiency specifically how to cut back on RAM usage? I've noticed this too that very gradually the RAM usage has tended to rise.

There may be a few areas in the code that have some unpatched memory leaks, but these are fairly small leaks, and the bulk of the RAM usage is not really reversible. Its the fact that there are so many unused outputs in the RAM. So its my opinion that the majority of the RAM consumption will be here to stay, unless you go chain swap which in my opinion should be a last resort reserved for emergencies or disfunctionally large chains.

Just out of curiosity,

Is it possible to make a light version Mintcoin wallet? A wallet version that takes less RAM/CPU even if that means it doesn't stake/mint. Also, does breaking the blockchain into multiple separate files help with RAM usage? Right now my mintcoin blockchain is all in one big file. I am wondering if that has any impact of RAM/CPU. Does anyone else have just one file, or do people have multiple?

See pic below of my Mintcoin Folder with just one blockchain file, and my CPU/RAM usage:
