This guide will teach you how to rewind the SPACE blockchain.

This applies to both Spacecoind and Spacecoin-QT.

Please Note

When rewinding, make sure you choose a block a bit before the block when your error occurred.

Certain times a rewind will fail and you will need to resync the blockchain.


  1. Close/stop your spacecoin wallet.

  2. Navigate to the spacecoin-qt/spacecoin folder.

  3. Run spacecoin-qt/spacecoind with the option -rewind=xxxxxx. xxxxxx is the block height it will rewind to. Ex: spacecoin-qt -rewind=313131

    On windows, go to your spacecoin-qt file, right click and select Create Shortcut. Then right click on the shortcut and select Properties. Then go to the Target field on the Shortcut page of the Properties screen. Add -rewind=xxxxxxx directly after spacecoin-qt.exe.

  4. Let the blockchain rewind to the specified block and then sync to the latest block.
