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

This applies to both Spacecoind and Spacecoin-QT.

Please Note

A reindex will rebuild all of the blockchain data. It is useful for times when the blockchain is stuck during sync.

Certain times a reindex won’t be enough to fix the current state 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 -reindex. Ex: spacecoin-qt -reindex

    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 -reindex directly after spacecoin-qt.exe.

  4. Let the blockchain reindex all of the downloaded blocks.
