What's New in RC3 (10 commits since RC2)

Critical Bug Fixes

• Fix DGB loss bug - Wallet-controlled change addresses now used for all DD transactions. Previously, DGB change was sent to random keys the wallet didn't control, causing permanent loss of funds.
• Fix consensus rejection - Non-P2TR outputs (like P2WPKH change) are now correctly allowed in mint transactions. Previously valid mints were rejected with "bad-collateral-script".

Network Reset

• New testnet7 - Fresh testnet environment separate from previous testnet data
• New P2P port 12029 - All nodes and oracles now use port 12029
• Revert EASY POW - Production-ready mining difficulty for realistic testing

Test Improvements

• Enhanced Qt testnet script with comprehensive DGB/DD balance tracking
• Updated validation test expectations for new change output handling

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:

testnet=1
server=1
txindex=1

[test]
digidollar=1
algo=sha256d
addnode=oracle1.digibyte.io

Windows Setup

Data Directory

%APPDATA%\DigiByte\

Config file: %APPDATA%\DigiByte\digibyte.conf

Testnet data stored in: %APPDATA%\DigiByte\testnet7\

Steps:

1. Press Win + R, type %APPDATA%\DigiByte and press Enter
2. Create a new text file named digibyte.conf (make sure to remove .txt extension)
3. Paste the config contents above and save
4. Run digibyte-qt.exe from the extracted folder
5. The wallet will create testnet7\ subfolder automatically

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet7]"
• You should see a DigiDollar tab in the sidebar

macOS Setup

Data Directory

~/Library/Application Support/DigiByte/

Config file: ~/Library/Application Support/DigiByte/digibyte.conf

Testnet data stored in: ~/Library/Application Support/DigiByte/testnet7/

Steps:

1. Open Terminal and create config:

mkdir -p ~/Library/Application\ Support/DigiByte
cat > ~/Library/Application\ Support/DigiByte/digibyte.conf << 'EOF'
testnet=1
server=1
txindex=1

[test]
digidollar=1
algo=sha256d
addnode=oracle1.digibyte.io
EOF

1. Extract the downloaded archive and remove quarantine:

xattr -cr ~/Downloads/digibyte-9.26.0-rc3-*-apple-darwin

1. Run the wallet:

# For Apple Silicon (M1/M2/M3/M4):
~/Downloads/digibyte-9.26.0-rc3-arm64-apple-darwin/bin/digibyte-qt

# For Intel Mac:
~/Downloads/digibyte-9.26.0-rc3-x86_64-apple-darwin/bin/digibyte-qt

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet7]"
• You should see a DigiDollar tab in the sidebar

Ubuntu/Linux Setup

Data Directory

~/.digibyte/

Config file: ~/.digibyte/digibyte.conf

Testnet data stored in: ~/.digibyte/testnet7/

Steps:

1. Open Terminal and create config:

mkdir -p ~/.digibyte
cat > ~/.digibyte/digibyte.conf << 'EOF'
testnet=1
server=1
txindex=1

[test]
digidollar=1
algo=sha256d
addnode=oracle1.digibyte.io
EOF

1. Extract and run:

cd ~/Downloads
tar xzf digibyte-9.26.0-rc3-x86_64-linux-gnu.tar.gz
./digibyte-9.26.0-rc3-x86_64-linux-gnu/bin/digibyte-qt

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet7]"
• You should see a DigiDollar tab in the sidebar

Getting Testnet DGB

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

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

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 12029
• 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

Downloads

Upgrading from RC2

Important: RC3 uses a new testnet (testnet7) with port 12029.

1. Update your config to remove the port from addnode (12029 is now default):

   addnode=oracle1.digibyte.io

2. Old testnet5 data can be deleted - the new testnet7 data will be stored automatically in:

   • Windows: %APPDATA%\DigiByte\testnet7\
   • macOS: ~/Library/Application Support/DigiByte/testnet7/
   • Linux: ~/.digibyte/testnet7/
