# Fork notes
|
|
|
|
`plm-electrumx` is a fork of [spesmilo/electrumx](https://github.com/spesmilo/electrumx) adapted to
|
|
Palladium (PLM), the coin of [palladiumcore](https://github.com/palladium-coin/palladiumcore).
|
|
|
|
## 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 were taken from `src/chainparams.cpp` and `src/chainparamsbase.cpp` of palladiumcore.
