**Data format:**
```

| H1_1 | H2_1 |

```
A remote log is a simply mapping from message identifiers to their corresponding address in a CAS.
| Message Identifier (H1) | CAS Hash (H2) |
| ---------------- |---------------|
| H1_3 | H2_3 |
| H1_2 | H2_2 |
| H1_1 | H2_1 |
| | |
| *address to next page* |
Optionally, the content itself can be included, just like it normally would be
sent over the wire.
| Message Identifier (H1) | Content |
| ---------------- |---------------|
| H1_3 | C3 |
| H1_2 | C2 |
| H1_1 | C1 |
| | |
| *address to next page* |
Here the upper section indicates a list of ordered pairs, and the lower section contains the address for the next page chunk. `H1` is the native hash function, and `H2` is the one used by the CAS. The numbers corresponds to the messages. To indicate which CAS is used, a remote log SHOULD use a multiaddr.
