What's New in RC6

Network Reset - Testnet9

• New testnet9 network - Fresh testnet environment with clean blockchain state
• New P2P port 12031 - All nodes and oracles now use port 12031
• Proper emission schedule - 72,000 DGB initial block rewards (Period I) for first 67 blocks
• Improved difficulty adjustment - Proper DigiShield/MultiShield retargeting with harder initial targets
• Compressed fork schedule - All features active within first 550 blocks for rapid testing

HD Key Derivation

• Deterministic DigiDollar keys - DD keys now use HD derivation from wallet seed
• Wallet restore support - Position reconstruction during wallet rescan
• Persistence tests - New test coverage for key persistence across wallet restarts

Tier Derivation Fixes

• Off-by-one fix - Corrected tier derivation during wallet restore
• TX timing tolerance - Fixed tier calculation with transaction timing variance
• Test improvements - Updated tier derivation tests for edge cases

UI Improvements

• Receive DD tab redesign - Improved layout and usability
• New addresses on top - Most recent generated addresses appear first
• Long-term mint warning - Triple warning for mints in high liquidation tiers

Documentation

• Updated presentation materials - New 5-minute presentation deck
• Improved wallet images - Updated screenshots

Upgrade Notes - IMPORTANT

RC6 requires a fresh testnet. Your existing testnet8 data will NOT work.

Migration Steps:

1. Download RC6
2. Delete or rename your old testnet data:
   • Windows: %APPDATA%\DigiByte\testnet8\
   • macOS: ~/Library/Application Support/DigiByte/testnet8/
   • Linux: ~/.digibyte/testnet8/
3. Update your config file to use testnet9 settings (see below)
4. Launch RC6 - it will create a new testnet9 directory

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=sha256d
addnode=oracle1.digibyte.io
rpcuser=digibyte
rpcpassword=digibyte123

Windows Setup

Step 1: Download and Install

Download digibyte-9.26.0-rc6-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 [testnet9]"
• You should see a DigiDollar tab in the sidebar

Data Directory Reference

• Config: %APPDATA%\DigiByte\digibyte.conf
• Testnet data: %APPDATA%\DigiByte\testnet9\

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=sha256d
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 [testnet9]"
• 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/testnet9/

Ubuntu/Linux Setup

Data Directory

~/.digibyte/

Config file: ~/.digibyte/digibyte.conf

Testnet data stored in: ~/.digibyte/testnet9/

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=sha256d
addnode=oracle1.digibyte.io
rpcuser=digibyte
rpcpassword=digibyte123
EOF

1. Extract and run:

cd ~/Downloads
tar xzf digibyte-9.26.0-rc6-x86_64-linux-gnu.tar.gz
./digibyte-9.26.0-rc6/bin/digibyte-qt

Verify It's Working

• Title bar should say "DigiByte Core - Wallet [testnet9]"
• 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 8 confirmations before spending mined coins (reduced from 100 in testnet9)

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 sha256d -o http://127.0.0.1:14025 -O digibyte:digibyte123 -t 4 --coinbase-addr=dgbt1qYOURADDRESSHERE

Windows (PowerShell):

.\minerd.exe -a sha256d -o http://127.0.0.1:14025 -O digibyte:digibyte123 -t 4 --coinbase-addr=dgbt1qYOURADDRESSHERE

Parameters explained:

• -a sha256d - Use SHA256d algorithm (matches algo=sha256d 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

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 12031
• 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]
• SHA256d is recommended for fastest CPU mining

"Transaction fee too high"

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