docker-entrypoint.sh uses the given SSL_CERTFILE/SSL_KEYFILE, or the certificate in the electrumx-ssl volume, and generates a self-signed one (10 years) only when none exists, never overwriting it, as clients pin it. It also sets SERVICES (tcp 50001 + ssl 50002). SSL is on by default. Documented in README.md and DEPLOY.md. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

# plm-electrumx

|
Language: Python (>= 3.10)
|
|
```
|
|
|
|
`plm-electrumx` is an [Electrum](https://electrum.org) protocol server for Palladium (PLM), the coin of
|
|
Palladium Core. It is a fork of
|
|
[spesmilo/electrumx](https://github.com/spesmilo/electrumx) that supports Palladium only.
|
|
It connects to your Palladium full node and indexes the blockchain, allowing efficient querying of
|
|
the history of arbitrary addresses.
|
|
|
|
## Running
|
|
|
|
### With Docker (next to the Palladium node)
|
|
|
|
ElectrumX joins the Docker network `palladium`, created by the node's compose project, and reaches the node
|
|
as `palladiumd:2332`. RPC and ZMQ of the node are not published on the host, so nothing else is exposed.
|
|
|
|
1. Start the node (a compose service named `palladiumd` on the network `palladium`). Its `~/.palladium/palladium.conf` needs
|
|
`server=1` and `txindex=1` (no `prune`).
|
|
2. `cp .env.example .env` and set `PLM_RPC_USER` / `PLM_RPC_PASSWORD` to the RPC credentials of that file
|
|
(use a dedicated `rpcauth` user for anything public).
|
|
3. `docker compose up -d --build`
|
|
|
|
The first start builds the database from the node from genesis, which takes a while; follow it with
|
|
`docker compose logs -f electrumx`. The database is the `electrumx-db` volume. Electrum clients connect to
|
|
TCP port 50001 (`ELECTRUMX_TCP_PORT` in `.env`) and SSL port 50002 (`ELECTRUMX_SSL_PORT`). SSL is on by default:
|
|
a self-signed certificate is generated on the first start, kept in the `electrumx-ssl` volume and reused on every
|
|
later start (or use your own, see [DEPLOY.md](DEPLOY.md)). To announce a public server to the network, set
|
|
`REPORT_SERVICES` in `.env`. Settings are in `.env` and `docker-compose.yml`; the image defaults are in the
|
|
`Dockerfile`. Ports, firewall, SSL, RPC credentials and troubleshooting are in [DEPLOY.md](DEPLOY.md).
|
|
|
|
### Without Docker
|
|
|
|
Requirements: Python >= 3.10, a synced Palladium node with `server=1` and `txindex=1` (no pruning),
|
|
and one of the DB engines (`pip install ".[leveldb]"` or `pip install ".[rocksdb]"`).
|
|
|
|
pip install ".[rocksdb]"
|
|
DB_ENGINE=rocksdb DB_DIRECTORY=/path/to/db \
|
|
DAEMON_URL=http://rpcuser:rpcpassword@127.0.0.1:2332/ \
|
|
SERVICES=tcp://:50001 electrumx_server
|
|
|
|
`COIN` defaults to `Palladium` and `NET` to `mainnet` (`testnet` and `regtest` are also available).
|
|
All settings are environment variables, documented in `docs/environment.rst`; `docs/HOWTO.rst`
|
|
describes a full installation.

## Fork notes
|
|
|
|
### Starting point
|
|
|
|
The first commit of this repository is an unmodified snapshot of upstream
|
|
[spesmilo/electrumx](https://github.com/spesmilo/electrumx) at commit
|
|
`280cb339aa158e099eb936033eecd15719770651`
|
|
("Merge pull request #389 from SomberNight/202607_release_2_0", upstream release 2.0.0, 3 July 2026).
|
|
The upstream history itself is not included. All Palladium-specific changes are in the commits after it:
|
|
|
|
git log --reverse
|
|
|
|
### Updating from upstream
|
|
|
|
There is no common git history with upstream, so `git merge` does not work. Apply the upstream
|
|
changes since the snapshot as a patch instead:
|
|
|
|
git remote add upstream https://github.com/spesmilo/electrumx.git # once
|
|
git fetch upstream
|
|
git log 280cb33..upstream/master --oneline # what changed upstream
|
|
git diff 280cb33 upstream/master | git apply --3way
|
|
|
|
Conflicts in files this fork deleted (see below) are resolved by keeping them deleted. After an update,
|
|
replace `280cb33` above with the new upstream commit that was applied.
|
|
|
|
### Removed from upstream
|
|
|
|
All other coins: their classes in `coins.py`, their transaction deserializers (`lib/tx.py`,
|
|
`tx_dash.py`, `tx_axe.py`), the session/daemon/block-processor subclasses only they used, their
|
|
tests and fixtures, and the altcoin pip extras. `Bitcoin` was folded into `Palladium`.
|
|
When merging upstream, resolve modify/delete conflicts on these files by keeping them deleted.
|
|
|
|
### Palladium specifics
|
|
|
|
- Palladium Core is based on Bitcoin Core 0.19. It has no `getindexinfo`, `txospenderindex` or
|
|
`submitpackage`, so the daemon version/index checks are disabled for `COIN=Palladium`, and
|
|
`blockchain.outpoint.subscribe` and `blockchain.transaction.broadcast_package` return a daemon
|
|
error to clients.
|
|
- The daemon must run with `txindex=1`.
|
|
- Same genesis blocks as Bitcoin (mainnet, testnet3, regtest), 80-byte headers, sha256d PoW, segwit.
|
|
- Parameters (address prefixes, ports, genesis hashes) were taken from the Palladium Core chain parameters.
