ElectrumX - Reimplementation of electrum-server

Licence:	MIT
Language:	Python (>= 3.7)
Original Author:	Neil Booth

This project is a fork of kyuupichan/electrumx. The original author dropped support for Bitcoin, which we intend to keep.

ElectrumX allows users to run their own Electrum server. It connects to your full node and indexes the blockchain, allowing efficient querying of history of arbitrary addresses. The server can be exposed publicly, and joined to the public network of servers via peer discovery. As of May 2020, a significant chunk of the public Electrum server network runs ElectrumX.

Adding new coin

Hello guys :)

Im learning how to add electrumx to new coin, and i could use some pointers.

Im kinda stuck at lib/coins.py file.

Help with Blackcoin, missing coinstake output

At the moment we are validating the Blackcoin coin code, and we are running into this balance difference situation between the electrumx db and the native blockchain (wallet and explorer).

It might be incompatibility between Blackcoin and the libraries that we currently (not?) use , but we could really need a push into the right direction. The case:

get_balance result from electrum_server (captured from the app)

{"jsonrpc":"2.0","id":"795","method":"blockchain.scripthash.get_balance","params":["61695a4c3c3922a8357d71bc0b3c774890451d8619ab62ed8d1e1068c24640fb"]}
{"jsonrpc": "2.0", "result": {"confirmed": 1100000000000, "unconfirmed": 0}, "id": "795"}

from the native wallet we see a different balance, which we can partly explain, because of some coinstakes not being mature yet. But we are still "missing" 551.5 BLK. (11551.5 - 11000 BLK)

"total_balance": 16500.56397743,
"balance": 11551.50000000,
"staked_balance": 4949.06397743,

The missing 551 BLK can be seen on the Explorer as part of this tx
https://chainz.cryptoid.info/blk/tx.dws?11101448.htm (check Raw Transaction tab)

 "value": 551.5,
 "n": 1,
 "scriptPubKey": {
    "asm": "02e884c3c32bdaddc9b2ffdd2cafc1c7b73ff4f7cafe3885a129974b3b72e18d35 OP_CHECKSIG",
    "hex": "2102e884c3c32bdaddc9b2ffdd2cafc1c7b73ff4f7cafe3885a129974b3b72e18d35ac",
    "reqSigs": 1,
    "type": "pubkey",
    "addresses": [
       "BPzTQdCPobZ5f6j1EJjAgsRv7m3JfeLBmy"

So the mature coinstake output can not been seen back on the address via Electrum.

checking this via RPC also confirms it

$ electrumx_rpc query BPzTQdCPobZ5f6j1EJjAgsRv7m3JfeLBmy
