9 Structure of a DATEX Block

9.1 Overview

A DATEX Block consists of 4 main sections:

  • A Routing Header, which mainly contains information about the sender and receivers of the block, and important information about the block (e.g. block size)
  • A Block Header, which contains metadata about the current block (type, timestamp, id, flags)
  • A Encrypted Header that is part of the optionally encrypted section of the block, and contains secret information that is only visible to the receivers of the block
  • A Body, which contains executable DATEX instructions
