An Electrum Server written in Java

This is designed as replacement for the python electrum server: https://github.com/spesmilo/electrum-server

1. The inital blockchain sync is multithreaded and a good bit faster than the python implementation (2 - 3 days with a fast system and SSD)

2. It is good to have multiple implementations of things in general

DB: Install and setup mangodb. A single node instance is just fine. Run mongodb on SSD if possible.

Make your SSL cert: ./makekey.sh

Build: ant jar

Config: cp jelly.sample.conf jelly.conf edit jelly.conf as makes sense

Run: java -Xmx4g -Xss256k -jar run/Jelectrum.jar jelly.conf

Feel free to connect to my instance which should be running the latest version.

b.1209k.com 50001 (tcp)
b.1209k.com 50002 (ssl)

1. IRC for advertising server.

2. Whatever cleverness is being done for UXTO for Electrum 2.0. I'll have to wait to see how this shakes out and then implement here.

3. HTTP/HTTPS. I see no strong reason to support those over TCP and SSL+TCP. I imagine it wouldn't be too hard but I don't see the need. If someone feels otherwise, let me know.

4. The following commands that clients don't seem to issue (yet):

blockchain.address.listunspent
blockchain.address.get_balance
blockchain.address.get_proof
blockchain.address.get_mempool
blockchain.utxo.get_address

(To check this list compare src/blockchain_processor.py from electrum-server to StratumConnection.java)
