Please explain the Blob file? And why its needed?

[Dvalin21]

Trying to figure out a few things, seeing how this tablet is the only tablet that i've seen with a "blob" file. All comments and answers welcomed

Blob files are parts of the firmware on the tablet and have very specific uses. Exactly what do you want to know, and what are you trying to do? Misuse of .blobs can easily brick your tablet.

A bunch of stuff packed into a container for easier handling. Relatively tamper proof cause you need special tools to pack/unpack it.
For this tablet the blob contains the entire software: boot loader, kernel, recovery and rom
