|
Please note that this package is intended to enable btcd to support different
|
|
|
|
database backends and is not something that a client can directly access as only
|
|
|
|
one entity can have the database open at a time (for most database backends),
|
|
|
|
and that entity will be btcd.
|
|
|
|
|
|
|
|
When a client wants programmatic access to the data provided by btcd, they'll
|
|
|
|
likely want to use the [btcrpcclient](https://github.com/btcsuite/btcrpcclient)
|
2017-05-25 18:29:23 +02:00
|
|
|
package which makes use of the [JSON-RPC API](https://github.com/btcsuite/btcd/tree/master/docs/json_rpc_api.md).

|
|
|
However, this package could be extremely useful for any applications requiring
|
|
|
|
Bitcoin block storage capabilities.
|
|
|
|
|
|
|
|
The default backend, ffldb, has a strong focus on speed, efficiency, and
|
|
|
|
robustness. It makes use of leveldb for the metadata, flat files for block
|
|
|
|
storage, and strict checksums in key areas to ensure data integrity.
|
|
|
|
|
|
|
|
