The underlying storage format didn't change, so the instructions above should work

It should work with latest Bitcoin Core (0.16+).
Didn't test with Parity or with Bitcoin Cash nodes...

Thanks!
This project was designed for personal use (e.g. optimized for HDD, no DoS prevention mechanisms).

Currently, it doesn't utilize SSD for better performance (so it would be hard to support thousands users), but there is a WIP branch for a new (more SSD-friendly) indexing schema here:
https://github.com/romanz/electrs/commits/new-index

Sorry for the delayed response - you can use a TLS-terminating proxy (such as https://hitch-tls.org/).
See https://github.com/romanz/electrs/commit/288cda518c3df6d49ed6d27fcd8f9f10d69a84cd#diff-9d70860c70981206f00c69a429b69ad1.

Cool, glad to hear that it works

Thanks a lot!
Please let me know if there are any issues/problems

Thanks for the compliment


Good point, will add a document for that!

Hello all,

I was working on this project for the last few months, so a user could run his own Electrum server, with required hardware resources not much beyond those of a full node (using ideas from ElectrumX [1], Electrum Personal Server [2] and bitcoincore-indexd [3]).

The code and usage instructions can be found here:
https://github.com/romanz/electrs

The server indexes the entire Bitcoin blockchain, and the resulting index [4] enables fast queries for any given user wallet, allowing the user to keep real-time track of his balances and his transaction history using the Electrum wallet [5].
Since it runs on the user's own machine, there is no need for the wallet to communicate with external Electrum servers, thus preserving the privacy of the user's addresses and balances.

Features:
 * Supports latest Electrum protocol [6].
 * Maintains an index of transaction inputs and outputs, allowing fast balance queries
 * Fast synchronization of the Bitcoin blockchain (~2.5 hours for ~185GB @ June 2018) on modest hardware [7]
 * Low CPU & memory usage (after initial indexing)
 * Low index storage overhead (~20%), relying on a local full node for transaction retrieval
 * Efficient mempool tracker allowing better fee estimation [8].
 * `-txindex` is not required for the Bitcoin node
 * Uses `rust-bitcoin` library [9] for efficient serialization/deserialization of Bitcoin transactions
 * Uses a single RocksDB [10] database, for better consistency and crash recovery

Hope you'll find it useful
