[**2. LevelDB library documentation**](https://github.com/google/leveldb/blob/master/doc/index.md) **is online and bundled with the source code.**

> LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.

```
#include <cassert>
#include "leveldb/db.h"

leveldb::DB* db;
leveldb::Options options;
options.create_if_missing = true;
leveldb::Status status = leveldb::DB::Open(options, "/tmp/testdb", &db);
assert(status.ok());
...
```

* Data is stored sorted by key.
* Callers can provide a custom comparison function to override the sort order.
* The basic operations are `Put(key,value)`, `Get(key)`, `Delete(key)`.
* Users can create a transient snapshot to get a consistent view of data.

## Work in progress: <a href="#id-7c08" id="id-7c08"></a>

1. Test in integration in cross-chain communication as well as cross-chain transactions.
2. To add core stats including TVL on the TRON network and stablecoin transactions
3. To optimize services like resource management, information inquiry and data analysis
4. Test in Metauniverse Aggegator operation
