Also referred to as Devicetree Blob (DTB). It is a flat binary encoding of data (primarily devicetree data, although other data is possible as well). The data is internally stored as a tree of named nodes and properties. Nodes contain properties and child nodes, while properties are name-value pairs.
The Devicetree Blobs (.dtb files) are compiled from the Devicetree Source
files (.dts) through the Devicetree compiler (DTC).
On Linux systems that support this, the blobs can be accessed in
/sys/firmware/fdt:
The encoding of strings used in the strings_block and structure_block is
actually a subset of ASCII:

Example files:
This page hosts a formal specification of Flattened Devicetree Format using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
