SHSH blobs is digital signature signed on firmware which is unique for each iPhone, iPod touch and iPad. Whenever we try to upgrade or restore a firmware on any if iDevice, ECID (Exclusive Chip ID) is passed to Apple servers to generate signature. Without signature, iTunes simply will not proceed to restore. As soon as Apple release a new version of OS, Apple stops signing older version of iOS, hence making it almost impossible to restore iDevice to older firmware.
SHSH blob is also verified at the time of boot of an iDevice, which ensures that iOS is not corrupt or hacked. In case if you are using jailbroken iPhone, iPod, or iPad, you must save SHSH blob so that you can downgrade your iDevice whenever needed.
