The DPS uses BadgerDB to store datasets of state changes and block information to build all the indexes required for random protocol and execution state access.
The value under this key keeps track of the first finalized block.
| Length (bytes) | 1 |
|---|---|
| Type | byte |
| Description | Index type prefix |
| Example Value | 1 |
The value stored (only once) is the height of the first indexed block.
The value under this key keeps track of the last finalized block.
| Length (bytes) | 1 |
|---|---|
| Type | byte |
| Description | Index type prefix |
| Example Value | 2 |
The value stored (updated each indexed block) is the height of the last indexed block.
In order to provide an efficient implementation of the Rosetta API, this index maps block heights to block headers. The header contains the metadata for a block as well as a hash representing the combined payload of the entire block.

The value stored at that key is the height of the referenced state commitment's block.
In this index, keys map the block height to the state commitment hash.
| Length (bytes) | 1 |

| Example Value | 4 |
425 |
The value stored at that key is the state commitment of the referenced block height.
The events index indexes events grouped by block height and transaction type. The block height is first in the index so that we can look through all events at a given height regardless of type using a key prefix.
