What's New in RC13

🐛 Bug Fixes & Improvements

RC13 is a stabilization release with Qt GUI improvements and RPC fixes.

Qt GUI Fixes

• Oracle Price Auto-Refresh in Mint Widget — The DigiDollar Mint widget now automatically refreshes the oracle price, ensuring users always see current pricing when minting DUSD
• Improved RPC Exception Handling — Better error handling in DigiDollar RPC calls prevents GUI crashes when the backend returns unexpected data
• Lock Tier Display Names Fixed — The DigiDollar GUI widgets now correctly display lock tier names (was showing incorrect tier labels)

RPC Fixes

• getalloracleprices Client Conversion — Fixed missing entry in the client conversion table that was preventing proper RPC response handling

Commits Since RC12

fix(rpc): add getalloracleprices to client conversion table
fix(qt): add oracle price auto-refresh timer to DD Mint widget
fix(qt): improve exception handling in DigiDollar RPC calls
fix(qt): correct lock tier display names in DigiDollar GUI widgets

Technical Changes

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

• Phase 2 Multi-Oracle Testing — This release continues 4-of-8 Schnorr threshold oracle consensus on testnet with live exchange prices.
• Testnet Only — All DGB and DUSD on testnet have no real value.

Upgrade Notes

RC13 uses the same testnet13 network as RC12 (port 12030). Your existing testnet data and wallets will work — no migration needed.

If you're upgrading from RC12, simply replace the binaries and restart.

If Upgrading from RC11 or Earlier:

1. Close your old wallet
2. Delete old testnet data:
   • Windows: Delete %APPDATA%\DigiByte\testnet10\, testnet11\, and testnet12\
   • macOS: Delete ~/Library/Application Support/DigiByte/testnet10/, testnet11/, and testnet12/
   • Linux: Delete ~/.digibyte/testnet10/, ~/.digibyte/testnet11/, and ~/.digibyte/testnet12/
3. Download and install RC13
4. Launch with -testnet flag

Quick Start Guide

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 testnet)

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://127.0.0.1:14026 -O digibyte:digibyte123 -t 4 --coinbase-addr=dgbt1qYOURADDRESSHERE

Windows (PowerShell):

.\minerd.exe -a sha256d -o http://127.0.0.1:14026 -O digibyte:digibyte123 -t 4 --coinbase-addr=dgbt1qYOURADDRESSHERE

Parameters explained:

• -a sha256d — Use SHA256d algorithm (matches algo=sha256d in config)
• -o http://127.0.0.1:14026 — 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 — DD Transactions tab shows complete transaction history (now auto-refreshes!)
6. Coin Control — Use manual DD input selection for advanced redemptions
7. Address Book — Save frequently used DD addresses for quick sending
8. Export History — Export DD transactions to CSV for record keeping

Oracle Operator Setup (Phase 2 Test)

Want to run an oracle node for the Phase 2 multi-oracle test? Here's the simple version:

Prerequisites

• DigiByte Core RC13 built from source with curl support
• An assigned oracle ID (0–6 for testnet, contact the maintainer)

Two-Command Setup

# Step 1: Create wallet and generate oracle key (one-time)
digibyte-cli -testnet createwallet "oracle"
digibyte-cli -testnet -rpcwallet=oracle createoraclekey <your_oracle_id>

# Step 2: Start your oracle (after every node restart)
digibyte-cli -testnet -rpcwallet=oracle startoracle <your_oracle_id>

Step 1 generates a Schnorr keypair, stores the private key in your wallet, and returns the public key. Send the X-only public key (32-byte hex) to the maintainer for inclusion in chainparams.cpp.

Step 2 loads the private key from your wallet and starts the oracle price feed thread. Your node will automatically fetch DGB/USD prices from multiple exchanges (minimum 2 sources required) and broadcast signed price messages to the network.

Known Issues

• Testnet oracle keys (oracles 1–6) use known test values (SHA256 hash-derived). Real operator keys will be swapped before mainnet.
• Mainnet oracle consensus remains disabled (nDigiDollarPhase2Height = INT_MAX)
• startoracle must be re-run after every digibyted restart

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]
• SHA256d is recommended for fastest CPU mining

"No wallet is loaded" when running oracle commands

• Add -rpcwallet=oracle to your createoraclekey and startoracle commands

"Oracle not configured" from startoracle

• Run createoraclekey first to generate and store the key in your wallet

"Transaction fee too high"

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

"Old testnet data causing crashes"

• Delete your testnet10, testnet11, and testnet12 folders completely (see Upgrade Notes above)
• RC13 uses testnet13 blockchain
