## Type

| Code | Desc       |
|-----:|:-----------|
| 1    | The result is a validation result. |
| 2    | The result is a heart beat result. |
| 4    | The result indicates a status.     |

## Heartbeat

| Code | Desc       |
|-----:|:-----------|
| 1    | Successful heart beat detected. |

## Status

| Code | Desc       |
|-----:|:-----------|
| 0    | Unknown status. |
| 1    | NIS is stopped. |
| 2    | NIS is starting. |
| 3    | NIS is running. |
| 4    | NIS is booting the local node (implies NIS is running). |
| 5    | The local node is booted (implies NIS is running). |
| 6    | The local node is synchronized (implies NIS is running and the local node is booted). |
| 7    | NIS local node does not see any remote NIS node (implies running and booted). |
| 8    | NIS is currently loading the block chain from the database. In this state NIS cannot serve any requests. |

## NemRequestResult

| Code | Desc       |
|-----:|:-----------|
|  0   | Neutral result. A typical example would be that a node validates an incoming transaction and realizes that it already knows about the transaction. In this case it is neither a success (meaning the node has a new transaction) nor a failure (because the transaction itself is valid). |
|  1   | Success result. A typical example would be that a node validates a new valid transaction. |
|  2   | Unknown failure. The validation failed for unknown reasons. |
|  3   | The entity that was validated has already past its deadline. |
|  4   | The entity used a deadline which lies too far in the future. |
|  5   | There was an account involved which had an insufficient balance to perform the operation. |
|  6   | The message supplied with the transaction is too large. |
|  7   | The hash of the entity which got validated is already in the database. |
|  8   | The signature of the entity could not be validated. |
|  9   | The entity used a timestamp that lies too far in the past. |
| 10   | The entity used a timestamp that lies in the future which is not acceptable. |
| 11   | The entity is unusable. |
| 12   | The score of the remote block chain is inferior (although a superior score was promised). |
| 13   | The remote block chain failed validation. |
| 14   | There was a conflicting importance transfer detected. |
| 15   | There were too many transaction in the supplied block. |
| 16   | The block contains a transaction that was signed by the harvester. |
| 17   | A previous importance transaction conflicts with a new transaction. |
| 18   | An importance transfer activation was attempted while previous one is active. |
| 19   | An importance transfer deactivation was attempted but is not active. |
