<!-- the previous hash could be; null, broadcast endorsement, self-endorsement, det lower 64 or random nonce -->

When building the list of hashes the `Previous Manifest Hash` is known from the previous Manifest. For the first built Manifest this value is null filled. The `Current Manifest Hash` is null filled while ASTM Messages are hashed and fill the `ASTM Messages Hashes` section. When all messages are hashed the `Current Manifest Hash` is computed over the `Previous Manifest Hash`, `Current Manifest Hash` (null filled) and `ASTM Messages Hashes`. This hash value replaces the null filled `Current Manifest Hash` and becomes the `Previous Manifest Hash` for the next Manifest.

In the US, the required ASTM Messages to be transmitted every second are: Basic ID (0x1), Location (0x2), and System (0x4). Typical implementations will most likely send at a higher rate (2x sets per cycle) resulting in 6 frames sent per cycle.

<!-- do we regard the the set when sent twice a second as a retransmission or as an update? -->

> Informational Note: In Europe, the Operator ID Message (0x5) is also included; pushing the frame count to 8 per cycle. In Japan, two Basic ID (0x0), Location (0x1), and Authentication (0x2) are required.

To calculate the frame count of a given DRIP Authentication Message the following formula is used:
