Inquiry about the decision to discontinue support for dashcoin

[stephenoseiowusu]

Hello, I am revisting this project after many years. I know it supported dashcoin at some point in time. What led to the discontinue of support for dashcoin. Can I use previous versions to use dashcoin wallets.

I have been able to edit the providers.json but I would like more insight to be able to add my own dashcoin node.

[mccwdev]

Support for Dash was dropped because of lack of time to maintain reliable and up-to-date code.

Also not enough public api's are available for Dash or Dash testnet to run your own software or wallet and for instance update transactions information.

[leewardhenry4]

Dash will soon be contacting you to keep this project alive with dash. As they are looking to expand. They will provide whatever you asked for. They will test your library. Just keep a lookout for any emails from dash whether in spam or junk or inbox.

Subject: Proposal for Integrating Dash-SPV as a Service Provider for Bitcoinlib

DearBitcoin lib team,

I hope this letter finds you well. I am writing to propose an integration of Dash-SPV as a service provider within Bitcoinlib to enable seamless interactions with the Dash blockchain, including features like wallet balance querying, transaction broadcasting, and SPV-based querying. This integration could be a significant enhancement to Bitcoinlib, especially in addressing the Dash node limitation issue that has been affecting its support for Dash.

Background: As you may know, Dash-SPV (Simple Payment Verification) is a lightweight protocol for interacting with the Dash blockchain that relies on Electrum-Dash servers. This protocol allows for wallet operations, such as checking balances and broadcasting transactions, without the need to run a full Dash node. Electrum-Dash servers use this SPV protocol to provide services to lightweight clients, making it possible to interact with Dash in a decentralized way.

However, a challenge currently exists with Bitcoinlib's support for Dash. Due to the lack of sufficient Dash nodes in the network, it is difficult to provide reliable services for tasks like querying wallet balances and broadcasting transactions. This has led to limited functionality for Dash within Bitcoinlib, which impacts users who want to integrate Dash into their applications.

Proposed Solution: I propose integrating Dash-SPV support within Bitcoinlib by utilizing Electrum-Dash servers as a service provider. This would allow Bitcoinlib users to interact with Dash via the SPV protocol, enabling wallet balance queries, transaction broadcasts, and other Dash-specific operations.

By using public Electrum-Dash servers, or even private instances, Bitcoinlib could bypass the need to run a full Dash node, thus solving the insufficient Dash node issue. This integration would also expand Bitcoinlib's capabilities, offering users an easy way to work with Dash alongside other cryptocurrencies.

How Dash-SPV Could Help: Dash-SPV leverages the Electrum protocol, which provides a simple and efficient way to interact with Dash through lightweight clients. By integrating this service into Bitcoinlib, we would be able to:

Query wallet balances for Dash addresses without needing a full node.
Broadcast transactions to the Dash network, enabling seamless transactions.
Resolve the insufficient node problem, allowing users to access Dash functionality without relying on full node availability.
Specific Libraries and Tools Needed: To implement Dash-SPV functionality within Bitcoinlib, the following Python libraries can be used:

requests: This is a simple library for making HTTP requests to Electrum-Dash servers and interacting with the SPV protocol. It’s essential for sending JSON-RPC requests to Electrum-Dash servers. Install it via: pip install requests

pyelectrum: This Python library can be used to interact with Electrum servers (including Electrum-Dash) to query balances and broadcast transactions. It will handle the Electrum protocol required for Dash-SPV interactions. Install it via: pip install pyelectrum

bitcoinlib (optional): This library is for general Bitcoin and cryptocurrency wallet operations and can be extended to work with Dash-SPV by integrating it with Electrum-Dash servers. If needed, Bitcoinlib can be used to create wallets, sign transactions, and interact with the Dash network via the Electrum-SPV protocol. Install it via: pip install bitcoinlib

json: Python’s built-in json library is used to handle JSON-RPC requests and responses when communicating with the Electrum-Dash server.

Example Python Integration (Using PyElectrum or Custom SPV Client): I’ve outlined an example below that demonstrates how to interact with Electrum-Dash servers using Python. The solution can be expanded to integrate directly with Bitcoinlib:

import requests import json

The Electrum-Dash server to use (public or private)
server_url = "http://electrum1.dash.org:50001" # Replace with your desired Electrum-Dash server

Wallet address to query
address = "XvTehcnHGsi7dszU7nvQWj3AX63uz9dPyT" # Replace with an actual Dash address

Prepare the JSON-RPC payload to check balance
payload = { "jsonrpc": "2.0", "method": "blockchain.address.get_balance", # The Electrum-Dash method for checking balance "params": [address], "id": 1 }

Send the request
response = requests.post(server_url, json=payload)

Parse and handle the response
if response.status_code == 200: result = response.json() if 'result' in result: balance = result['result']['confirmed'] # 'confirmed' balance in DASH print(f"Balance for address {address}: {balance} DASH") else: print(f"Error: {result.get('error', 'Unknown error')}") else: print(f"Error: Could not connect to the server, status code {response.status_code}")

This Python example demonstrates how to query the balance of a Dash address using Electrum-Dash servers. This can be easily extended within Bitcoinlib to provide the same functionality for Dash wallet operations.

Benefits of This Integration:

No Need for Full Nodes: By relying on Electrum-Dash servers, users can interact with the Dash blockchain without needing to maintain a full Dash node.
Increased Dash Support: Integrating Dash-SPV with Bitcoinlib allows the library to support Dash transactions and wallet functionality seamlessly, just as it does with Bitcoin and other cryptocurrencies.
Scalable Solution: This approach can easily scale by adding additional Electrum-Dash servers or switching to private servers for greater control.
I believe this integration will significantly improve Bitcoinlib’s functionality and open up new opportunities for developers working with Dash in the ecosystem.

Thank you for considering this proposal. I look forward to hearing your thoughts and would be happy to discuss this further if needed.

Best regards,
Safiuallah

Here's a list of Electrum-Dash servers (Electrum servers for Dash) that you can use to interact with the Dash blockchain. These servers implement the Electrum protocol, which allows you to access Dash blockchain data without downloading the entire blockchain.

List of Electrum-Dash Servers
Official Dash Electrum Servers

These are the official public servers provided by Dash developers:

Mainnet Servers:

electrumx1.dash.org - Port: 50001 (non-SSL), 50002 (SSL)
electrumx2.dash.org - Port: 50001 (non-SSL), 50002 (SSL)
Testnet Servers:

testnet1.dash.org - Port: 51001 (non-SSL), 51002 (SSL)
These servers support both SSL and non-SSL connections, and you can connect your Electrum-Dash wallet to these servers to interact with the Dash blockchain.

Community-Run Electrum Servers These are Electrum servers run by community members or independent projects:

electrum1.dashpay.io - Port: 50001 (non-SSL), 50002 (SSL)
electrum2.dashpay.io - Port: 50001 (non-SSL), 50002 (SSL)
electrum3.dashpay.io - Port: 50001 (non-SSL), 50002 (SSL)
These community-run servers might have additional configurations or improvements, but their uptime and availability may vary.

Public Electrum Servers Some public Electrum servers may also support Dash. While they are generally intended for Bitcoin, some may also support Dash:

electrum.blockstream.info (Primarily Bitcoin, but you can try to connect with Dash wallets.)
However, these are often Bitcoin-centric, so the recommended servers for Dash are the ones listed above.

Connecting to an Electrum-Dash Server
To connect your Electrum-Dash wallet (or any other compatible Electrum wallet) to one of the servers above, follow these steps:

Open Electrum-Dash (or any other Electrum wallet).
During wallet setup, when asked for a server, input the server address and port of one of the listed servers. For instance, you can use:
electrumx1.dash.org:50002 (SSL)
electrumx2.dash.org:50001 (non-SSL)
Your wallet will now connect to the chosen Electrum-Dash server and be able to interact with the Dash blockchain.
Important Notes:
SSL vs Non-SSL: Use SSL (Port 50002) for a more secure connection, if available.
Public Servers: While these servers are publicly available, they may have restrictions or rate-limiting to ensure fair usage. For heavy usage, it's recommended to run your own ElectrumX server.
Running Your Own ElectrumX Server for Dash
If you're building a custom solution and need more control over the Electrum server, you can run your own ElectrumX server for Dash by following the setup steps detailed in earlier conversations. This involves syncing the Dash blockchain with your own Dash full node and then running an ElectrumX server to serve clients.

Conclusion
You can use the official Dash servers (electrumx1.dash.org, electrumx2.dash.org) or community-run servers to connect to the Dash blockchain using Electrum-Dash. These servers allow lightweight wallets to interact with Dash without downloading the full blockchain.

Let me know if you need help setting up your wallet or running your own ElectrumX server!

[mccwdev]

Good to see there is a list of Electrum providers for Dash.

Bitconlib supports connections to ElectrumX server since the latest version. So it should be easy to test the library with the Dash network.

If you add the Dash network settings in networks.json and the provider definitions in providers.json you can for instance create a wallet and test.

[stephenoseiowusu]

Im going to do this and provide update on it:

Modify the networks.json file to add the Dash network. Add the following parameters to the file:

Name: Dash
Symbol: DASH
Network name: Dash Mainnet
Subnet name: dash
Address version: 4c
P2SH address version: 10
WIF prefix: cc
xprv prefix: 02fe52cc
xpub prefix: 02fe52f8
BIP44 ID: 5
Set electrum to true
Modify the providers.json file to add ElectrumX servers for Dash. Add the following server details:

Provider: Electrum
Network: dash
Servers:
URL: electrumx1.dash.org, Port: 50002 (SSL)
URL: electrumx2.dash.org, Port: 50002 (SSL)
Test Dash connectivity by creating a wallet in Bitcoinlib. Use the following Python script:

Import Wallet from bitcoinlib
Create a new wallet with the Dash network
Check the wallet balance
Get a new Dash address
Optionally, send Dash to another address (if you wish to test sending)
Run the Python script:

Save the script as test_dash.py
Run it in the terminal using: python test_dash.py
Make sure your Bitcoinlib is up-to-date. Run the following command to upgrade:

pip install --upgrade bitcoinlib
By doing this, you will restore Dash support in your Bitcoinlib setup and be able to interact with the Dash blockchain using the ElectrumX servers.

[stephenoseiowusu]

Okay Here is a quick report on the information: it worked I was able to create a dash wallet and was able to get an address. However I have come to the conclusion that in the past bitcoinlib update that removed dash it also affected whatever sqllite schema you had. I ran into several errors trying to call update_utxos the following letter describes the error. It has something to do with the sqllite database schema.

Problem Description:
While developing a Dash cryptocurrency wallet using the bitcoinlib library (v0.7.2), the following errors occurred due to database schema incompatibilities:

anti_fee_sniping Column Missing:

Error: sqlite3.OperationalError: no such column: wallets.anti_fee_sniping

Context: Triggered during wallet creation after upgrading bitcoinlib.

index Column Missing:

Error: sqlite3.OperationalError: no such column: cache_transactions.index

Context: Occurred when updating UTXOs (wallet.utxos_update()).

Troubleshooting Steps Taken:

Database Deletion:

Deleted outdated SQLite databases at:

/Users/[username]/.bitcoinlib/database/bitcoinlib.sqlite

/System/Volumes/Data/Users/[username]/.bitcoinlib/database/bitcoinlib.sqlite

Library Reinstallation:

Performed a clean install of bitcoinlib to ensure no cached schema conflicts.

Code Adjustments:

Explicitly set witness_type='legacy' for Dash compatibility (Dash does not support SegWit).

Root Cause:

Outdated Database Schema:
After upgrading bitcoinlib, existing databases lacked new columns (anti_fee_sniping, index) required by the updated schema.

Dash Compatibility:
Dash uses legacy address formats, necessitating witness_type='legacy' to avoid SegWit-related errors.

Solution:

Nothing yet....

[mccwdev]

Did you try to set default_witness_type=legacy in the config.ini?

[stephenoseiowusu]

Okay so here is the final work through guys it is a lot to get dash working again but it worked I was able to send transaction, create a wallet, and get addresses. You can not use bitcoinlib built in sqlite library it is missing a table. You will need your own mysql or postgre database and install pythons required database libraries that bitcoinlib uses.

First update config.ini to make dash use legacy witness type, below is my full config.ini:

#
# BITCOINLIB - Configuration file
# © 2020 March - 1200 Web Development <http://1200wd.com/>
#

# Default network when creating wallets, transaction, keys, etc.
;default_network=bitcoin

# Default witness_type for new wallets and keys
;default_witness_type=legacy

[dash]
default_witness_type = legacy  ; Force legacy addresses for Dash

[bitcoin_cash]
default_witness_type = legacy  ; Bitcoin Cash does not support SegWit
default_network = bitcoin_cash

[bitcoin_sv]
default_witness_type = legacy  ; Bitcoin SV does not support SegWit
default_network = bitcoin_sv

# Use caching for service providers
;service_caching_enabled=True

# Maximum number of errors before service request fails
;service_max_errors=3

# Maximum number of transactions per service request
;max_transactions=20

# Number of seconds block_count is cached
;block_count_cache_time=3

[logs]
# Enable own logging for this library. If true logs will be stored in the log/bitcoinlib.log file.
# Set to False if this library is part of another library or software and you want to handle logs yourself.
;enable_bitcoinlib_logging=True

# Log file name. Relative paths will be based in data_dir directory
;log_file=~bitcoinlib.log

# Loglevel for this library, options: CRITICAL, ERROR, WARNING, INFO, DEBUG, NOTSET
;loglevel=WARNING

Here is the work around. I will how my networks.json:

1.Update cofig.ini with:

[dash]
default_witness_type = legacy ; Force legacy addresses for Dash

2. Update providers.json
3. Update networks of json.
4. delete sqllite database and allow bitcoinlib to recreate it or use your own custom postgre or mysql database

The SQLite database wasn’t working due to a schema mismatch caused by:

1. Outdated Database Schema
   Root Cause:
   When you upgraded bitcoinlib, the library introduced new database columns (like anti_fee_sniping and index).
   However, your existing SQLite database retained the old schema and lacked these columns, causing errors like:
   sqlite3.OperationalError: no such column: cache_transactions.index.

Why SQLite Failed:
SQLite is a file-based database. When you upgrade bitcoinlib, it doesn’t automatically migrate old schemas. The existing bitcoinlib.sqlite file remained tied to the outdated schema.

[stephenoseiowusu]

just copy my config.ini and providers.json and networks.json to get dash coin working again, replace those files with what you copied in the bitcoinlib library. Hopefully the devs will test this and get dash readded again. Electrum servers are free and not rate limited. As with the snipping fee column in sqllite it may have been cause by my cached sqlolite database or something is missing in the code. To get around that just install docker and get a mysql or postgre image (they are free) and create a container. Then just use the database uri with your root user and password and pass in the uri whenever you use bitcoinlib Wallet or Service classes. It will work.

Hopefully the devs please can they patch this fix in next bitcoinlib version. Electum servers are free and are usually not rate limited

example:
You need:
-pip install mysqlclient-
-pip install sqlalchemy

database_uri = 'mysql+pymysql://root:password@localhost/bitcoinlib'
wallet = Wallet.create(
        name='dash_mysql_wallet',
        network='dash',
        witness_type='legacy',
        db_uri=database_uri
    )

On a separate note after experimenting the same procedure can be done for bitcoin cash and bitcoin sv if you want since they are also electrum based. However upon further inspection some more code tweaks are needed since those where removed form the bitcoin lib library. Just some formatting needs to be done to the wallet addresses and that the transactions under them need no witness fields:

transaction.py

class Transaction:
    def serialize(self, network='BTC'):
        if network in ['BCH', 'BSV']:
            self.witnesses = []  # Remove witness data
        return super().serialize()

encoding.py

from cashaddress import convert  # pip install cashaddress

def to_address(public_key_hash, network="BCH"):
    if network == "BCH":
        legacy_address = pubkeyhash_to_address(public_key_hash, network=network)
        return convert.to_cash_address(legacy_address)
    # ... existing code ...

Electrum Server Configuration
BSV relies on Electrum servers for blockchain queries. Add servers to providers.json or override them programmatically:

Example: Override Electrum servers for BSV

from bitcoinlib.services.services import Service

Service(network='BSV').providers = [
    {'host': 'sv.1209k.com', 'port': 50002, 'protocol': 's'},
    {'host': 'electrumsv.hsmiths.com', 'port': 50002, 'protocol': 's'}
]

Example with editing providers.json (recommended):

{
  "providers": {
    // ... existing providers (BTC, LTC, etc.) ...

    "BCH": [
      {
        "provider": "electrum",
        "host": "bch.imaginary.cash",
        "port": 50002,
        "protocol": "s",
        "priority": 0
      },
      {
        "provider": "electrum",
        "host": "electroncash.de",
        "port": 50002,
        "protocol": "s",
        "priority": 1
      }
    ],
    "BSV": [
      {
        "provider": "electrum",
        "host": "sv.1209k.com",
        "port": 50002,
        "protocol": "s",
        "priority": 0
      },
      {
        "provider": "electrum",
        "host": "electrumsv.hsmiths.com",
        "port": 50002,
        "protocol": "s",
        "priority": 1
      }
    ]
  }
}

finally add the bsv and bch network definitions:
networks.py

# networks.py
NETWORK_DEFINITIONS = {
    # ... existing networks ...

    "BCH": {
        "network_name": "Bitcoin Cash",
        "default_witness_type": "legacy",
        "segwit_support": False,
        "bip32_prefix": (0x0488ade4, 0x0488b21e),  # Same as BTC
        "wif_prefix": 0x80,
        "address_prefix": 0x00,  # Legacy P2PKH (1...)
        "address_prefix_p2sh": 0x05,  # Legacy P2SH (3...)
        "cashaddr_prefix": "bitcoincash",  # CashAddr format
        "dust_threshold": 546,
        "script_types": ["p2pkh", "p2sh"],
        "fee_per_kb": 5000,
    },
    "BSV": {
        "network_name": "Bitcoin SV",
        "default_witness_type": "legacy",
        "segwit_support": False,
        "bip32_prefix": (0x0488ade4, 0x0488b21e),
        "wif_prefix": 0x80,
        "address_prefix": 0x00,  # Legacy P2PKH (1...)
        "address_prefix_p2sh": 0x05,  # Legacy P2SH (3...)
        "dust_threshold": 546,
        "script_types": ["p2pkh", "p2sh"],
        "fee_per_kb": 5000,
    }
}

FInal Testing to see if changes persisted:

from bitcoinlib.services.services import Service

# Check BCH servers
service_bch = Service(network="BCH")
print(service_bch.providers)  # Should list servers from providers.json

# Check BSV servers
service_bsv = Service(network="BSV")
print(service_bsv.providers)

[stephenoseiowusu]

This worked for me but again you need a mysql or postgre database server.

[mccwdev]

This worked for me but again you need a mysql or postgre database server.

There are probably still remains of the old sqlite database from version 0.7.x. Database versions are not compatible between major versions (i.e. 0.6.x and 0.7.x). When you install bitcoinlib the databases are created from scratch, so there shouldn't be any missing fields.

You can migrate the old database by importing the private keys and recreate the wallets in the new database. See tools/import_database.py for some example code.

yes thankyou just got it working, I was able to add dash and now its working with dash. saved all my files I changed which are above for future reference. Thank you.

[stephenoseiowusu]

After testing I hope this fix can be added into the next update.

[mccwdev]

Where did you find the list of Electrum-Dash servers? None of them seems to be working, or am I missing something?

[stephenoseiowusu]

found them on some forum for crypto. Some developers were posting about different free crypto nodes. I just copied and pasted the configuration

[stephenoseiowusu]

Hello, I found them here: https://github.com/pshenmic/electrum-dash/blob/master/electrum_dash/servers.json and some crypto currency site

[stephenoseiowusu]

I just wanted to add a few more dash snode servers here: I got them working. This is the providers.json file.
