* Supports Electrum protocol [v1.2](https://electrumx.readthedocs.io/en/latest/protocol.html)
* Maintains an index over transaction inputs and outputs, allowing fast balance queries
* Fast synchronization of the Bitcoin blockchain (~2.5 hours for ~185GB @ June 2018) on [modest hardware](https://gist.github.com/romanz/cd9324474de0c2f121198afe3d063548)

* Low index storage overhead (~20%), relying on a local full node for transaction retrieval
* Efficient mempool tracker (allowing better fee [estimation](https://github.com/spesmilo/electrum/blob/59c1d03f018026ac301c4e74facfc64da8ae4708/RELEASE-NOTES#L34-L46))
