What is DigiDollar?

DigiDollar is a USD-pegged stablecoin built natively into DigiByte. It uses an over-collateralized model where users lock DGB to mint DUSD at the current oracle price of DGB.

The world's first truly decentralized stablecoin native on a UTXO blockchain, enabling stable value transactions without centralized control.

DGB becomes the strategic reserve asset (21B max, only 2.23 DGB per person on Earth right now). Everything happens inside DigiByte Core wallet. You never give up control of your private keys. No centralized company, fund or pool. Pure decentralization.

Current Status

• Single Oracle Testing - This beta uses one oracle node for price feeds. Production will use a decentralized oracle network.
• Testnet Only - All DGB and DUSD on testnet have no real value.

Quick Start Guide

Step 1: Download

Download the appropriate file for your platform from the Downloads section below and extract it.

Step 2: Create Config File

Create the config file in your platform's data directory with the following contents:

# DigiByte Configuration
# Global settings (apply to all networks)
testnet=1
server=1
txindex=1

# Testnet-specific settings
[test]
digidollar=1
digidollarstatsindex=1
algo=scrypt
addnode=oracle1.digibyte.io
rpcuser=digibyte
rpcpassword=digibyte123

Windows Setup

Step 1: Download and Install

Download digibyte-9.26.0-rc5-win64-setup.exe and install normally.

Step 2: First Launch (Testnet Mode)

You must launch in testnet mode. Open PowerShell and run:

& "C:\Program Files\DigiByte\digibyte-qt.exe" -testnet

The wallet will start in testnet mode and create the data directory automatically.

Step 3: Create Config File

1. Press Win + R, type %APPDATA%\DigiByte and press Enter
2. Create a new text file named digibyte.conf (remove the .txt extension)
3. Paste the config contents from Step 2 above and save

Step 4: Restart

Close the wallet and launch again from PowerShell:

& "C:\Program Files\DigiByte\digibyte-qt.exe" -testnet

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet8]"
• You should see a DigiDollar tab in the sidebar

Data Directory Reference

• Config: %APPDATA%\DigiByte\digibyte.conf
• Testnet data: %APPDATA%\DigiByte\testnet8\

macOS Setup

Step 1: Download and Extract

Download the .dmg file for your Mac and open it. Drag DigiByte-Qt to your Desktop.

Step 2: First Launch (Testnet Mode)

You must launch in testnet mode. Open Terminal and run:

cd ~/Desktop
./DigiByte-Qt.app/Contents/MacOS/DigiByte-Qt -testnet

If you get a security warning, right-click the app and select "Open", or run:

xattr -cr ~/Desktop/DigiByte-Qt.app

Then try the launch command again.

The wallet will start in testnet mode and create the data directory automatically.

Step 3: Create Config File

In Terminal:

mkdir -p ~/Library/Application\ Support/DigiByte
cat > ~/Library/Application\ Support/DigiByte/digibyte.conf << 'EOF'
# DigiByte Configuration
# Global settings (apply to all networks)
testnet=1
server=1
txindex=1

# Testnet-specific settings
[test]
digidollar=1
digidollarstatsindex=1
algo=scrypt
addnode=oracle1.digibyte.io
rpcuser=digibyte
rpcpassword=digibyte123
EOF

Step 4: Restart

Close the wallet and launch again from Terminal:

cd ~/Desktop
./DigiByte-Qt.app/Contents/MacOS/DigiByte-Qt -testnet

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet8]"
• You should see a DigiDollar tab in the sidebar

Data Directory Reference

• Config: ~/Library/Application Support/DigiByte/digibyte.conf
• Testnet data: ~/Library/Application Support/DigiByte/testnet8/

Ubuntu/Linux Setup

Data Directory

~/.digibyte/

Config file: ~/.digibyte/digibyte.conf

Testnet data stored in: ~/.digibyte/testnet8/

Steps:

1. Open Terminal and create config:

mkdir -p ~/.digibyte
cat > ~/.digibyte/digibyte.conf << 'EOF'
# DigiByte Configuration
# Global settings (apply to all networks)
testnet=1
server=1
txindex=1

# Testnet-specific settings
[test]
digidollar=1
digidollarstatsindex=1
algo=scrypt
addnode=oracle1.digibyte.io
rpcuser=digibyte
rpcpassword=digibyte123
EOF

1. Extract and run:

cd ~/Downloads
tar xzf digibyte-9.26.0-rc5-x86_64-linux-gnu.tar.gz
./digibyte-9.26.0-rc5-x86_64-linux-gnu/bin/digibyte-qt

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet8]"
• You should see a DigiDollar tab in the sidebar

Getting Testnet DGB

Option 1: GUI Console Mining

Mine testnet DGB directly using the GUI console:

1. Go to the Receive tab and create a new address (copy your dgbt1... address)
2. Go to Window > Console
3. Type: generatetoaddress 1 dgbt1qYOURADDRESSHERE
4. Press Enter to mine 1 block
5. Wait for 100 confirmations before spending mined coins

Option 2: CPU Miner (Recommended for Continuous Mining)

Use cpuminer to mine testnet DGB in the background. Make sure your wallet is running and synced first.

Download cpuminer: https://github.com/pooler/cpuminer

Build from source or download a release for your platform.

Run cpuminer:

Linux/macOS:

./minerd -a scrypt -o http://127.0.0.1:14025 -O digibyte:digibyte123 -t 4 --coinbase-addr=dgbt1qYOURADDRESSHERE

Windows (PowerShell):

.\minerd.exe -a scrypt -o http://127.0.0.1:14025 -O digibyte:digibyte123 -t 4 --coinbase-addr=dgbt1qYOURADDRESSHERE

Parameters explained:

• -a scrypt - Use scrypt algorithm (matches algo=scrypt in config)
• -o http://127.0.0.1:14025 - RPC endpoint (testnet RPC port)
• -O digibyte:digibyte123 - RPC credentials from your config (user:password)
• -t 4 - Number of CPU threads to use (adjust based on your CPU)
• --coinbase-addr=dgbt1q... - Your testnet receive address

The miner will continuously mine blocks and send rewards to your address.

Testing DigiDollar Features

Once your wallet is synced and you have testnet DGB:

1. View Network Status - The DigiDollar Overview tab shows oracle price and network collateralization
2. Mint DUSD - Lock DGB as collateral to create DigiDollars
3. Send DUSD - Transfer DigiDollars to other testnet addresses
4. Redeem DUSD - Burn DigiDollars to unlock your DGB collateral (full position only)
5. View History - New DD Transactions tab shows complete transaction history

Network Information

Troubleshooting

"DigiDollar tab not appearing"

• Verify digidollar=1 is under [test] section in config
• Verify testnet=1 is at the top of config (not under any section)
• Restart the wallet after config changes

"Not connecting to network"

• Check your firewall allows port 12030
• Verify addnode=oracle1.digibyte.io is under [test] in config

"Oracle price shows 0 or N/A"

• Wait for sync to complete
• The oracle broadcasts price updates every few minutes
• Check Window > Console: getoracleprice

"Mining not working"

• Ensure algo=sha256d is in your config under [test]
• Default algorithm is scrypt which requires more computation

"Transaction fee too high"

• DigiDollar transactions require 0.1 DGB minimum fee - this is expected
• This ensures reliable network propagation

Downloads

Upgrading from RC4

1. Simply download and run RC5 - no config changes needed
2. Your existing testnet8 data will be used automatically
3. The macOS Qt fixes should resolve any text visibility issues
