A new wallet version 1.8 has been released for Jumbucks. This is a relatively minor update but does require some interaction from the user for upgrading as the data directory has been renamed. For existing users, please pay attention to the Upgrade steps below. New users may install the wallet as is.

For Windows users this update also includes standalone executable wallets for 32-bit and 64-bit systems.

Other improvements include new RPC commands and faster start up times.

Upgrade steps

The data directory and configuration file has been renamed. This change was necessary to fully deprecate the old CoinmarketsCoin name to switch over to Jumbucks.

  • Backup your wallet.dat file
  • Shut down the current version 1.7 wallet
  • Rename the data directory the the new name described below. Rename configuration file (if you manually created one) from coinmarketscoin.conf to jumbucks.conf
  • Install the new version
  • Start up the new version 1.8 wallet and verify everything works
    ** Windows users MAY need to follow the step of deleting everything in their data directory except for their wallet.dat file since the wallet is in a new executable format. This would require a full resync of the blockchain and steps to sync from a bootstrap.dat file are included below.

OLD data directory:

Windows < Vista: C:\Documents and Settings\Username\Application Data\CoinmarketsCoin
Windows >= Vista: C:\Users\Username\AppData\Roaming\CoinmarketsCoin
Mac: ~/Library/Application Support/CoinmarketsCoin
Unix: ~/.coinmarketscoin

NEW data directory:

Windows < Vista: C:\Documents and Settings\Username\Application Data\Jumbucks
Windows >= Vista: C:\Users\Username\AppData\Roaming\Jumbucks
Mac: ~/Library/Application Support/Jumbucks
Unix: ~/.jumbucks

Changes

  • Updated some QT wallet images such as the splash screen
  • Added getwalletinfo RPC call
  • RPC command liststealthaddresses - Multiple address fix
  • RPC command liststealthaddresses - Results reformatted to be consistent with rest of RPC calls
  • RPC command sendtoaddress - Call sendtostealthaddress if passed a stealth address
  • RPC command sendtoaddress & sendtostealthaddress - Reordered params moving narration to end
  • OpenSSL DER fix to allow for latest versions of OpenSSL
  • Decrease the default number of blocks to check at startup to 500
  • Modify DNS seeds to use getjumbucks.com domain and deprecate old coinmarketscoin.com domain
  • Remove redundant stake modifier checkpoints checks
  • Reduce nStakeCombineThreshold to 500 for smoother network staking

Bootstrap.dat file

The Bootstrap.dat allows a new Jumbucks client (not synced) to rapidly import the initial blocks from a local file instead of slowly downloading blocks from random peers. This significantly reduces the time it takes to get a client synced with the current blockchain (minutes instead of hours). Simply having bootstrap.dat in Jumbucks' expected data directory will make your initial block sync much faster.

The current Bootstrap file is at block 540,621 (August 14, 2015).

Regardless of your operating system use the following steps to make use of the bootstrap.dat file:

  • Download bootstrap.dat.xz.
  • Verify the integrity of bootstrap.dat.xz with the checksums.
  • Decompress to obtain bootstrap.dat.
  • Put it into the Jumbucks datadir. This is the same folder that contains wallet.dat and the blocks folder.
  • Delete bootstrap.dat.old if you want to recover some storage space.

Extract bootstrap.dat

Linux

Code:
xz -d bootstrap.dat.xz

Mac

You can obtain xz from Homebrew or MacPorts.

Windows

7Zip is a free utility that can decompress .xz files. The latest version of WinRAR also supports .xz files.

Copy bootstrap.dat to data directory

Copy bootstrap.dat to your data directory. After Jumbucks has used bootstrap.dat, the file will be renamed to bootstrap.dat.old; at this point you can choose to delete it or keep it.

Linux

Jumbucks' data directory is located in ~/.jumbucks/ by default.

Mac

Jumbucks' data directory should be located in ~/Library/Application Support/Jumbucks/.

Windows

Go to Start>Run (or press WinKey+R) and run: explorer %APPDATA%\Jumbucks
Jumbucks' data directory will open. "AppData" and "Application Data" are hidden by default in Windows.
