jelectrum
An Electrum Server written in Java
This is designed as replacement for the python electrum server: spesmilo/electrum-server
Reasons to exist
-
The inital blockchain sync is multithreaded and a good bit faster than the python implementation (2 - 3 days with a fast system and SSD)
-
It is good to have multiple implementations of things in general
DB Options
Not sure what to use? Use slopbucket or rocksdb.
More details DATABASE
How to run
Make your SSL cert: ./makekey.sh
Build: bazel build :all :Jelectrum_deploy.jar
Config: cp jelly.default.conf jelly.conf edit jelly.conf as makes sense
Run: while true do bazel-bin/Jelectrum jelly.conf done
Alternatively
bazel build :all :Jelectrum_deploy.jar will create a jar file that can be moved around: bazel-bin/Jelectrum_deploy.jar
My Instance
Feel free to connect to my instance which should be running the latest version. Note: these hosts are IPv6 only
jelectrum-core.1209k.com 50001 (tcp)
jelectrum-core.1209k.com 50002 (ssl)
jelectrum-cash.1209k.com 50001 (tcp)
jelectrum-cash.1209k.com 50002 (ssl)
What Doesn't Work
-
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.
-
The following commands that clients don't seem to issue (yet):
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)
Monitoring
If you are going to run it, monitor it!
I've made a monitoring tool that anyone to can use to monitor their electrum server (jelectrum or otherwise):
