## Scribe
`scribe` maintains a [rocksdb](https://github.com/lbryio/lbry-rocksdb) database containing the [LBRY blockchain](https://github.com/lbryio/lbrycrd) and provides an interface for python based services that utilize the blockchain data in an ongoing manner. Scribe includes two implementations of this interface:
* `scribe-hub` - an electrum server for thin-wallet clients (such as lbry-sdk), provides an api for clients to resolve and search claims published to the LBRY blockchain.
* `scribe-elastic-sync` - a utility to maintain an elasticsearch database of metadata for claims in the LBRY blockchain
`scribe` ([scribe.blockchain.service](https://github.com/lbryio/scribe/tree/master/scribe/blockchain/service.py)) - maintains a [rocksdb](https://github.com/lbryio/lbry-rocksdb) database containing the [LBRY blockchain](https://github.com/lbryio/lbrycrd) and provides an [interface](https://github.com/lbryio/scribe/tree/master/scribe/service.py) for python based services that utilize the blockchain data in an ongoing manner. Scribe includes two implementations of this interface:
* `scribe-hub` ([scribe.hub.service](https://github.com/lbryio/scribe/tree/master/scribe/hub/service.py)) - an electrum server for thin-wallet clients (such as lbry-sdk), provides an api for clients to resolve and search claims published to the LBRY blockchain.
* `scribe-elastic-sync` ([scribe.elasticsearch.service](https://github.com/lbryio/scribe/tree/master/scribe/elasticsearch/service.py)) - a utility to maintain an elasticsearch database of metadata for claims in the LBRY blockchain
Other features and overview of scribe:
* Uses Python 3.7-3.9 (3.10 probably works but hasn't yet been tested)
* Protobuf schema for encoding and decoding metadata stored on the blockchain ([scribe.schema](https://github.com/lbryio/scribe/tree/master/scribe/schema)).
* Blockchain processor that maintains an up to date rocksdb database ([scribe.blockchain.service](https://github.com/lbryio/scribe/tree/master/scribe/blockchain/service.py))
* [Rocksdb](https://github.com/lbryio/lbry-rocksdb/) based database containing the blockchain data ([scribe.db](https://github.com/lbryio/scribe/tree/master/scribe/db))
* Interface for python services to implement in order for them maintain a read only view of the blockchain data ([scribe.service](https://github.com/lbryio/scribe/tree/master/scribe/service.py))
* Electrum based server for thin-wallet clients like lbry-sdk ([scribe.hub.service](https://github.com/lbryio/scribe/tree/master/scribe/hub/service.py))
* Elasticsearch sync utility to index all the claim metadata in the blockchain into an easily searchable form ([scribe.elasticsearch.service](https://github.com/lbryio/scribe/tree/master/scribe/elasticsearch/service.py))
