* 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 (~5 hours for ~184GB @ June 2018) on modest hardware (without SSD)
* Fast synchronization of the Bitcoin blockchain (~2.5 hours for ~185GB @ June 2018) on modest hardware (no SSD)
* 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))
* Low CPU & memory usage (after initial indexing)
