Just to advise that jelectrum (with respect to
creating a new DB) is 50+ times faster than the existing python implementation (yes, you
can should download a database from the foundry for the python version but what fun is that). There are "costs" to running the jelectrum server, however...
1. The leveldb database is roughly 130GB
25G ELDB/electrum-leveldb-utxo-1000
So over 100GB larger
2. The amount of RAM needed on the server (and this could be tweaked more going forward I assume) is ideally 12+ GB
- I have been running the python version on a server with 8 GB and could get away with as little as 4GB
All that said, I am enjoying trying something new and can foresee this being the evolution of the current server software.
SO, for the adventurous, come give it a try!
