I like Mintcoin but I downloaded the wallet for windows and it would take almost a day to download for 6 months of a Blockchain. I wouldn't say this issue would have to do with the Blockchain size, more that the GUI needs improvement in how it connects and downloads the chain from other nodes. Something I have found quite useful when wanting to quickly sync a Blockchain is to have someone on the longest chain make a copy and publish it to Megaupload or Dropbox where you can download a 600-700MB Blockchain in about 20 minutes so you end up only needing to finish the last 1-2% of the Blockchain (you would need to test the security of this if you do this but you need to atleast change your RPC username and password). I have also been toying with the idea of how you could use Torrents to download the Blockchain in a spactical manner.
What some coins have also done in the past is swaps to a different Blockchain through an automated process and start from scratch once again. If you took it in terms of swapping for exactly the same thing, it would prune off all the excess Blockchain bloat and you can quickly sync again so then it stands to reason that it could become a piece of the Blockchain and regulate it's size.
I agree, this is a large issue. Took me 3 work days 8-5 to finish it last week.
I agree. Syncing the wallet is painful. Something needs to be done to speed up the process.
Yes I made a guide a little while ago on what to do to quickly sync a Blockchain and might be worth looking into a bit further because it would cut that 3 day Sync time down to about 1 hour.
I would like to state that I have had no problems with it but it doesn't mean that there may not be. It is a good idea to only receive files from people you trust and store your keys securely.Here is the guide I had made for it a couple months ago.
How to quickly sync your wallet with a QT client
Step 1Download the most up to date Client, and latest copy of the Blockchain and Colossuscoin.conf file
Windows Client 1.5.2ColossuscoinBlockchainApr17.rarColossuscoin.confColossuscoinJuly27th.rar (Including Conf file)Step 2Go to your Download folder in your computer, right click on Col 1.5.2.rar and extract the files to a folder in which you can find.
Step 3Open your ColossusCoin-qt.exe file for the first time, wait until it opens and then close the client, this will automatically create your roaming files for you. (Ignore this step if you already have had a client but wish to update or sync quicker).
Step 4Go to your Colossuscoin folder which is found in User/Appdata/Roaming/Colossuscoin and delete everything in the folder except your wallet.dat
Your wallet.dat contains your private keys, if you delete that you will permanently lose your coins so please make a backup of it before deleting anything.Step 5Go back to the folder in where you downloaded the files in Step 1, right click on the Blockchain file and extract the files to your Appdata/Roaming/Colossuscoin folder. Right click on Colossuscoin.conf file, copy it and paste it into the Appdata/Roaming/Colossuscoin folder as well. Your Colossuscoin Folder should now contain all the files you need.
Step 6Open your ColossusCoin-qt.exe client and let your client fully sync. If you have coins available to Stake, they will Stake once your client is fully Synced and you can leave it open until they are fully confirmed (which is 70 confirmations on the network)
Step 7 *optional*
If you would like to check your wallet for coins that may not be showing up in your wallet, click on "Help", "Debug Window" and click on the Console tab.
Type Checkwallet to check for any coins that may be missing and should say "wallet check passed" : true
If it returns "Mismatched Coins" Type Repairwallet and it will fix your balance.
