How to find a transaction on the grin blockchain:
-------------------------------------------------

If you have the slate file, you can get the shared transaction id with:
    cat payment_slate.json | jq .id

The transaction id will look like this:
    6d7e9c04-18b4-4b8f-b3a3-b52bd6e9b18a

You can then get the status from your wallet:

These steps describe one possible method to create a grin wallet offline and add coins - i.e cold-storage.

1) Download the grin-wallet - either the executable or the source code and compile it into an executable
2) Partition and format a USB thumb drive (drive 1)
3) Copy the grin-wallet executable to the USB thumb drive 1
4) Copy a Grin TX slate file to the USB thumb drive 1
5) On a second USB thumb drive, or a CD/DVD, (drive 2) create a bootable image (https://linuxmint-installation-guide.readthedocs.io/en/latest/burn.html)
6) Unplug your network cable
7) Boot the image you created on drive 2
8) Insert and mount the drive with grin-wallet and slate file (drive 1)
