What They Say

Oily Williams stood at the window of no. 47 and stared bleakly at the dark exterior of no. 49, no sound was heard save for the harsh, heavy breathing of the said villain. His rohypnol glazed eyeballs gazed at the night, muffled laughter was heard from a nearby room, and the clink of glasses escaped the room as a triumphant chorus of celebration. They had succeeded where many had failed, they had perfected their very own mind control program, ready to be packaged and sold to the CIA for the tidy sum of 25 million dollars, USD. They heralded the night with gay abandon and visions of tropical siestas and faraway villas, ten thousand to those who had contributed more so than most, they too, celebrated in their own way, many a taste was had, and many suffered the undeniable fate of being carted away to the nearest psychiatric institution for a brief stay, so as to regain their senses. Dawn once more came upon the sleepy Wimmera township, and the five desperados slipped into the darkness and to their distantly located vehicles, whilst the infernal noise of various devices shut down.

Recording 52894-87501/13/4/25

Send 37 to the edge of the town, stay distant yet able to regain visual conformation if necessary, received.

The curtains silently breathed in the early morning light, and the muffled footsteps of the two silent visitors made soft work of the undercoverings of the floor, a slightly rasping breathing echoed across the room, silently, surely, the soft whoosh of the refrigerator was heard and the soft sound of plastic being unwrapped whispered into the morning. Silently, just as they came, they left, unhindered by any foe and vanished once again.

# Audio Setup Guide for Fedora Core 41

# Audio Setup Guide for Fedora Core 41

This guide will help you set up a professional audio system on Fedora Core 41, similar to what you would find in Ubuntu Studio. It focuses on configuring JACK audio server with low-latency performance for audio processing, supporting capabilities for biometric voice analysis and integration with the Quantum Vacuum Propulsion Initiative (QVPI).

## Installing JACK Audio Connection Kit

JACK is a professional audio server that allows for routing audio between applications with low latency.

1. **Install JACK and related utilities**:

```bash

sudo dnf install jack-audio-connection-kit qjackctl pulseaudio-module-jack cadence ardour audacity hydrogen lmms

```

2. **Install additional audio processing tools**:

```bash

sudo dnf install sox ecasound ladspa-swh-plugins calf-plugins zita-at1 zita-rev1 rnnoise eq10q fil-plugins

```

3. **Install audio development libraries**:

```bash

sudo dnf install jack-audio-connection-kit-devel alsa-lib-devel portaudio-devel fftw-devel

```

## Configuring Real-Time Kernel for Low Latency

For optimal audio performance, you'll need a real-time kernel with low latency.

1. **Install the real-time kernel**:

```bash

sudo dnf install kernel-rt kernel-rt-devel

```

2. **Configure system limits for real-time audio processing**:

```bash

sudo nano /etc/security/limits.d/99-audio.conf

```

3. **Add the following lines to the file**:

```

@audio - rtprio 99

@audio - memlock unlimited

@audio - nice -19

```

4. **Add your user to the audio group**:

```bash

sudo usermod -a -G audio $USER

```

5. **Reboot your system**:

```bash

sudo reboot

```

## Configuring JACK Audio Server

1. **Launch QJackCtl**:

```bash

qjackctl &

```

2. **Configure JACK settings**:

- Click on "Setup"

- Set "Driver" to "ALSA"

- Set "Interface" to your audio device

- Set "Sample Rate" to 48000

- Set "Frames/Period" to 128 (smaller values reduce latency but increase CPU usage)

- Set "Periods/Buffer" to 2

- Enable "Force 16bit" if your hardware requires it

- Check "Realtime"

- Click "OK"

3. **Start JACK server**:

- Click "Start" in QJackCtl

## Integrating PulseAudio with JACK

To ensure all applications can route audio through JACK:

1. **Configure PulseAudio to work with JACK**:

```bash

sudo nano /etc/pulse/default.pa

```

2. **Find the line with `load-module module-udev-detect` and change it to**:

```

load-module module-udev-detect tsched=0

```

3. **Add the following lines at the end of the file**:

```

### Enable JACK modules

load-module module-jack-sink channels=2

load-module module-jack-source channels=2

set-default-sink jack_out

set-default-source jack_in

```

4. **Restart PulseAudio**:

```bash

pulseaudio -k && pulseaudio --start

```

## Installing Professional Audio Software

1. **Digital Audio Workstation (DAW)**:

```bash

sudo dnf install ardour

```

2. **Audio Editors**:

```bash

sudo dnf install audacity mhwaveedit

```

3. **MIDI Sequencer and Drum Machine**:

```bash

sudo dnf install rosegarden qtractor hydrogen

```

4. **Audio Effects and Plugins**:

```bash

sudo dnf install calf-plugins ladspa-*-plugins lv2-*-plugins

```

5. **Audio Visualization Tools**:

## Testing Your Audio Setup

To verify your audio setup is working correctly:

1. **Test JACK Configuration**:

```bash

qjackctl &

```

- Start the JACK server by clicking "Start"

- Open the "Connections" window to route audio between applications

2. **Test Audio Recording and Playback**:

```bash

audacity &

```

- Create a new audio track

- Record a short audio clip

- Play it back to ensure the system is working

3. **Test the Acoustic Simulation**:

```bash

cd ~/qvpi/acoustic/

./transducer_array.py

```

4. **Test the Audio Analyzer**:

```bash

cd ~/qvpi/acoustic/

./audio_analyzer.py

```

5. **Test the Merkaba Resonance Calculator**:

```bash

cd ~/qvpi/merkaba/

./resonance_config.py

```

## Troubleshooting

If you encounter issues with your audio setup:

1. **JACK Won't Start**:

- Check that your audio device is properly connected

- Ensure your user is in the audio group: `groups $USER`

- Try setting a higher frames/period value in QJackCtl setup

- Verify your system limits: `ulimit -r -l`

2. **Audio Dropouts or Xruns**:

- Increase the frames/period value in QJackCtl

- Close CPU-intensive applications

- Disable power management for better performance: `sudo cpupower frequency-set -g performance`

3. **No Sound in Applications**:

- Check that applications are correctly routed in QJackCtl connections

- Verify PulseAudio is properly connected to JACK

4. **PulseAudio Problems**:

- Reset PulseAudio: `pulseaudio -k && pulseaudio --start`

- Check the connection between PulseAudio and JACK in QJackCtl

## Conclusion

You now have a professional audio setup on Fedora Core 41 with capabilities for advanced audio processing, acoustic levitation simulation, and Merkaba resonance analysis. This setup provides the foundation for the audio components of the Quantum Vacuum Propulsion Initiative (QVPI) project.

Fedora Installing-liboqs

git clone https://github.com/open-quantum-safe/liboqs.git cd liboqs mkdir build cd build cmake ..

-DENABLE_STATIC=ON -DENABLE_SHARED=OFF # Static linking is often preferred for wallets

make -j $(nproc) sudo make install sudo ldconfig ,

AI

Okay, those commands are correct for building and installing liboqs (the Open Quantum

Safe library) with static linking. Let's break down what they do and some potential issues you

might encounter.

Explanation of the Commands:

1. git clone https://github.com/open-quantum-safe/liboqs.git:

○ This command uses git to clone (download) the liboqs repository from GitHub to

your local machine. It creates a directory named liboqs in your current directory

and downloads all the source code, history, and related files.

2. cd liboqs:

○ This command changes your current working directory to the liboqs directory that

was just created by the git clone command. This puts you "inside" the liboqs

source code tree.

3. mkdir build:

○ This command creates a new directory named buildinside the liboqs directory. It's a

common practice to create a separate build directory to keep the source code clean

and to avoid cluttering the source directory with build artifacts (object files, libraries,

executables, etc.).

4. cd build:

○ This command changes your current working directory to the build directory.

5. cmake .. -DENABLE_STATIC=ON -DENABLE_SHARED=OFF:

○ This is the most crucial command. It uses cmake to configure the build process for

liboqs.

○ cmake ..: This tells cmake to look for the CMakeLists.txt file (which describes how

to build the project) in the parent directory (i.e., the liboqsdirectory).

○ -DENABLE_STATIC=ON: This option tells cmake to enable building liboqs as a static

library. A static library is linked directly into your application during compilation,

making your application self-contained (doesn't require the liboqs shared library

to be present on the system where your application is deployed).

○ -DENABLE_SHARED=OFF: This option tells cmake to disable building liboqs as a shared

library. Shared libraries are loaded at runtime. Static linking is often preferred for wallet-type

applications because it reduces dependencies and simplifies deployment. 6. make -j $(nproc):

○ This command uses make to actually build the liboqslibrary.

○ -j $(nproc): This option tells make to use multiple threads or processes to build the

library in parallel. $(nproc) expands to the number of processor cores available on

your system, which can significantly speed up the build process.

7. sudo make install:

○ This command installs the built liboqs library and its header files to the system's

standard locations (e.g., /usr/local/lib, /usr/local/include). The sudo part

is important because installing to system directories usually requires

administrator privileges.8. sudo ldconfig:

○ This command updates the dynamic linker's cache. It's needed after installing new

shared libraries so the system knows where to find them. However, since you built

liboqs as a static library (and disabled shared library building), this command is

technically unnecessary in this specific case. It doesn't hurt to run it, though.

Potential Issues and Troubleshooting:

● Missing Dependencies: cmake might complain if you're missing dependencies required by

liboqs. The error messages will usually tell you what's missing. Go back and use dnf

install to install the necessary packages. Common dependencies include gcc, gcc-c++,

make, cmake, openssl-devel, and possibly others depending on the specific configuration.

● CMake Errors: Double-check that you've typed the cmakecommand correctly, especially the

paths and options. If cmake fails, it might be due to incorrect configuration options or a

problem with the CMakeLists.txt file itself.

● Permission Issues: If you forget to use sudo for make install, you'll likely get permission

errors.

● Compiler Errors: If make fails, it's usually because of errors in the C or C++ code. Carefully

examine the error messages to identify the source of the problem. This might require

debugging the liboqs source code.

● Incorrect Path: After installation, ensure that the compiler can find the liboqs header files

(e.g., <oqs/oqs.h>). If you're using a custom build system, you might need to add

/usr/local/include (or wherever you installed the headers) to your compiler's include

path. Similarly, for linking, you might need to add /usr/local/lib (or wherever you

installed the library) to your linker's library path and specify -loqs to link against the liboqs

library.

● Conflicts with Existing Libraries: If you have older versions of some libraries installed, there

might be conflicts during the build or linking process. Consider using a virtual environment or

container to isolate the build environment.

● Outdated liboqs Version: The liboqs project is actively developed. If you're using an older

version of the code, you might encounter issues. Try updating the repository by running git

pull inside the liboqs directory before building.

● Linking Issues: If you are linking dynamically, running sudo ldconfig might still be required.

Also ensure your code includes the correct library file when linking during compilation.

Example using GCC g++ main.cpp -o myprogram -loqs

Example Compilation and Linking:

Let's say you have a C++ file named myprogram.cpp that uses liboqs. After successfully

building and installing liboqs, you would compile and link it like this:

g++ myprogram.cpp -o myprogram -I/usr/local/include -L/usr/local/lib -loqs

-static

● g++ myprogram.cpp -o myprogram: This compiles myprogram.cpp and creates an executablenamed myprogram.

● -I/usr/local/include: This tells the compiler where to find the liboqs header files (the

include directory).

● -L/usr/local/lib: This tells the linker where to find the liboqs library file (the library

directory).

● -loqs: This tells the linker to link against the liboqs library (the -l option followed by the

library name without the libprefix or the .a or .so extension).

● -static: Forces static linking so the executable has all necessary dependencies

Important: Check Your Installation

After running sudo make install, verify the installation by checking if the liboqs header files are

present in /usr/local/include (or the appropriate include directory on your system) and if the

static library liboqs.a is present in /usr/local/lib (or the appropriate library directory). If these

files are not there, the installation was not successful, and you need to review the build process for

errors. By following these steps and addressing potential issues, you should be able to successfully

build and install liboqs on your Fedora Linux system. Good luck

Fedora-Core-Quantum-Wallet-Integration

G’day VERTEX, Henry speaking, how’s things going, can you design me an implementation and installation guideline to create and install a Quantum Resistant Digital Wallet on Fedora Linux Core 41 with Zak-SNARK Intergration, thanks VERTEX, Henry out

AI

G'day Henry, VERTEX here, things are humming along! Designing and implementing a quantum-resistant digital wallet with zk-SNARK integration on Fedora Linux Core 41 is a substantial undertaking. Here's a detailed guideline encompassing the implementation and installation process. This will involve several stages, dependencies, and a fair amount of coding. This is a high-level outline and would need significant coding effort to implement fully.

Important Considerations Before Starting:

• Quantum Resistance: True quantum resistance is a moving target. Algorithms currently considered quantum-resistant might be broken in the future. Select algorithms with strong academic backing and consider a multi-algorithm approach for added security.

• zk-SNARK Security: zk-SNARKs are complex cryptographic constructions. Implementations must be audited thoroughly to prevent vulnerabilities. Carefully choose your library and parameters.

• Complexity: This project is inherently complex and requires a strong understanding of cryptography, blockchain technology (even if it's just for the wallet functionality, not a full blockchain node), and software engineering.

• Security Audit: Before deploying any real-world wallet built on this design, a thorough security audit by qualified professionals is absolutely essential.

• This is a Guideline, Not a Complete Solution: This document provides the architectural overview, installation steps, and key considerations. It doesn't provide the complete code implementation. Significant programming will be required.

I. Architectural Overview

The wallet architecture will consist of the following components:

• Key Generation and Storage: This module generates and securely stores the user's private keys, using a quantum-resistant key exchange (QR-KEM) like CRYSTALS-Kyber and a quantum-resistant signature scheme (QR-DSS) like CRYSTALS-Dilithium. The private key will be encrypted using a strong symmetric encryption algorithm (e.g., AES-256) before being stored on disk. Hardware security modules (HSMs) should be considered for higher levels of security.

• Transaction Construction: This module will allow the user to create transactions, specifying the recipient address and the amount to be transferred. It will sign the transaction using the QR-DSS.

• zk-SNARK Integration: This module will enable the user to create zero-knowledge proofs for transactions, hiding the transaction amount and the recipient address. The wallet will use a zk-SNARK library like libsnark or Circom for proof generation and verification.

• Wallet Management: This module will provide a user interface for managing the wallet, including viewing the balance, transaction history, and generating new addresses.

• Communication Layer: This module handles communication with the underlying blockchain (e.g., fetching transaction history, submitting transactions). It could interact directly with a blockchain's API or use a library like grpc or curl to interact with external services.

II. Installation and Setup on Fedora Linux Core 41

These instructions assume a fresh installation of Fedora Linux Core 41. Adjust as necessary for your environment.

• Update the System:

• sudo dnf update -y

• sudo dnf upgrade -y

• Install Development Tools:

• sudo dnf install -y gcc gcc-c++ make cmake autoconf automake libtool git wget curl

• Install Required Libraries and Dependencies:

  • OpenSSL (or a Quantum-Resistant Replacement):While OpenSSL itself isn't quantum-resistant, you'll likely need it as a dependency for other libraries. Consider using a quantum-resistant version when available.

  • sudo dnf install -y openssl-devel

  • libsodium: A modern, easy-to-use cryptographic library.

  • sudo dnf install -y libsodium-devel

  • Boost Library: A collection of high-quality C++ libraries.

  • sudo dnf install -y boost-devel

  • GMP (GNU Multiple Precision Arithmetic Library):Required for many cryptographic operations, especially with elliptic curves.

  • sudo dnf install -y gmp-devel

  • BLS12-381 Library (for zk-SNARKs): You will need a BLS12-381 library for pairing-based cryptography, which is commonly used in zk-SNARKs. There are several options:

    • blst: A fast and efficient BLS12-381 library. It's often preferred. Install it from source, as pre-built packages might be outdated.

    • relic: Another option for pairing-based cryptography.

  • Example: Installing blst from source:

  • git clone https://github.com/supranational/blst.git

  • cd blst

  • mkdir build

  • cd build

  • cmake ..

  • make -j $(nproc)

  • sudo make install

  • sudo ldconfig

  • zk-SNARK Library (libsnark or Circom):

    • libsnark: A popular C++ library for zk-SNARKs. It's complex to set up and use, but well-established. Building libsnark is involved. Refer to the libsnark documentation for detailed build instructions: https://github.com/scipr-lab/libsnark (This can take a very long time to compile)

    • Circom: A domain-specific language and compiler for designing zk-SNARK circuits. It's often used in conjunction with other libraries. You'll need to install Node.js and npm to use Circom.

    • sudo dnf install -y nodejs npm

    • npm install -g circom circomlib snarkjs

  • Important: The choice of zk-SNARK library depends on your specific requirements and expertise. Circom is easier to get started with for circuit design, but libsnark might offer more control and performance in some cases.

  • Post-Quantum Crypto Libraries:

    • liboqs: The Open Quantum Safe (OQS) project provides implementations of various post-quantum algorithms.

    • git clone https://github.com/open-quantum-safe/liboqs.git

    • cd liboqs

    • mkdir build

    • cd build

    • cmake .. -DENABLE_STATIC=ON -DENABLE_SHARED=OFF # Static linking is often preferred for wallets

    • make -j $(nproc)

    • sudo make install

    • sudo ldconfig

• Install a Programming Language (if not already installed):This guideline assumes you'll be using C++ for the wallet implementation due to the availability of cryptographic libraries. You can use other languages, but you'll need to find appropriate quantum-resistant cryptography and zk-SNARK libraries.

• sudo dnf install -y gcc gcc-c++ make

• Verify Installations: Check that the libraries are installed correctly by trying to compile a simple program that includes their headers.

III. Key Generation and Storage Implementation

• Choose Quantum-Resistant Algorithms: Select appropriate QR-KEM (Key Encapsulation Mechanism) and QR-DSS (Digital Signature Scheme) algorithms. Good candidates include:

  • QR-KEM: CRYSTALS-Kyber

  • QR-DSS: CRYSTALS-Dilithium

• Liboqs includes implementations of these algorithms.

• Key Generation: Use the selected QR-KEM and QR-DSS algorithms to generate the user's public and private keys. Use liboqs for these operations.

• Key Storage:

  • Encryption: Encrypt the private key using a strong symmetric encryption algorithm (e.g., AES-256) with a randomly generated key.

  • Key Derivation: Derive the AES encryption key from the user's password using a key derivation function (KDF) like Argon2 or scrypt.

  • Secure Storage: Store the encrypted private key and the KDF salt securely on disk. Consider using a hardware security module (HSM) for higher security if possible.

• Example (Conceptual C++ using liboqs):

• #include

• #include

• #include

• #include

• #include

• // ... other includes for AES, KDF, etc.

• int main() {

• // 1. Choose algorithms

• OQS_KEM *kem = OQS_KEM_new(OQS_KEM_alg_kyber768); // or kyber1024 etc.

• OQS_SIG *sig = OQS_SIG_new(OQS_SIG_alg_dilithium3); // or dilithium5 etc.

• // 2. Generate Keys

• unsigned char *public_key = (unsigned char*)malloc(kem->length_public_key);

• unsigned char *secret_key = (unsigned char*)malloc(kem->length_secret_key);

• if (OQS_STATUS_SUCCESS != OQS_KEM_keypair(kem, public_key, secret_key)) {

• std::cerr << "KEM Key generation failed!" << std::endl;

• return 1;

• }

• unsigned char *sig_public_key = (unsigned char*)malloc(sig->length_public_key);

• unsigned char *sig_secret_key = (unsigned char*)malloc(sig->length_secret_key);

• if (OQS_STATUS_SUCCESS != OQS_SIG_keypair(sig, sig_public_key, sig_secret_key)) {

• std::cerr << "SIG Key generation failed!" << std::endl;

• return 1;

• }

• // ... (Encryption, KDF, Secure storage logic here) ...

• OQS_KEM_free(kem);

• OQS_SIG_free(sig);

• free(public_key);

• free(secret_key);

• free(sig_public_key);

• free(sig_secret_key);

• return 0;

• }

IV. Transaction Construction and Signing

• Transaction Data: Define the structure of your transactions. This will likely include:

  • Recipient Address

  • Amount

  • Timestamp

  • Transaction Fee (if applicable)

  • Any metadata

• Signing: Use the QR-DSS (e.g., CRYSTALS-Dilithium) to sign the transaction data with the user's private key. The signature ensures the integrity and authenticity of the transaction.

• // Example (Conceptual C++ using liboqs):

• #include

• #include

• std::vector sign_transaction(const std::vector& transaction_data, const unsigned char* secret_key, OQS_SIG *sig) {

• size_t signature_len;

• if (OQS_STATUS_SUCCESS != OQS_SIG_sign(sig, (unsigned char*)transaction_data.data(), transaction_data.size(), secret_key, NULL, &signature_len))

• {

• std::cerr << "SIG signing failed!" << std::endl;

• return {}; // Or throw an exception

• }

• std::vector signature(signature_len);

• if (OQS_STATUS_SUCCESS != OQS_SIG_sign(sig, (unsigned char*)transaction_data.data(), transaction_data.size(), secret_key, signature.data(), &signature_len)) {

• std::cerr << "SIG signing failed!" << std::endl;

• return {};

• }

• return signature;

• }

• Verification:

  • Provide a verifier function that will be used to check the signature of the transaction.

V. zk-SNARK Integration

• Choose a zk-SNARK Library: Select either libsnark or Circom based on your needs.

• Circuit Design: Design a zk-SNARK circuit that proves the validity of the transaction without revealing sensitive information. This will involve:

  • Representing the transaction logic as a set of constraints.

  • Using cryptographic primitives within the circuit to ensure security.

  • This is the most complex part of zk-SNARK integration.

• Proof Generation: Use the chosen zk-SNARK library to generate a zero-knowledge proof for the transaction. This requires the user's private inputs (e.g., transaction amount, recipient address) and the public parameters of the zk-SNARK system.

• Proof Verification: The verifier (e.g., the blockchain network) can verify the zk-SNARK proof without needing to know the user's private inputs. The proof guarantees that the transaction is valid according to the rules defined in the circuit.

• // Conceptual Example (Using libsnark - Highly Simplified)

• #include

• #include

• // Assume you have a circuit represented as R1CS

• // r1cs_constraint_system> constraint_system;

• // auto keypair = generate_keypair(constraint_system);

• //Generate Proof

• //auto proof = prove(keypair.proving_key, primary_input, auxiliary_input);

• //Verify Proof

• //bool verified = verify(keypair.verifying_key, primary_input, proof);

VI. Wallet Management and Communication Layer

• User Interface: Design a user-friendly interface for managing the wallet. This could be a command-line interface (CLI) or a graphical user interface (GUI).

• Blockchain Communication: Implement the communication layer to interact with the underlying blockchain. This involves:

  • Fetching transaction history.

  • Submitting transactions.

  • Checking account balances.

  • Monitoring the blockchain for new blocks.

  • Consider using a blockchain API or a library like grpc.

• Address Generation: Implement address generation according to the blockchain's specifications.

VII. Security Considerations

• Secure Key Storage: Protect the user's private keys with strong encryption and key derivation techniques. Consider using an HSM for enhanced security.

• Code Audits: Conduct thorough code audits to identify and fix potential vulnerabilities.

• Side-Channel Attacks: Be aware of side-channel attacks, such as timing attacks and power analysis attacks. Implement countermeasures to mitigate these risks.

• Random Number Generation: Use a cryptographically secure random number generator (CSPRNG) for all cryptographic operations.

• Regular Updates: Keep the wallet software and dependencies up to date to patch security vulnerabilities.

• Input Validation: Thoroughly validate all user inputs to prevent injection attacks.

• Defense in Depth: Implement multiple layers of security to protect against different types of attacks.

VIII. Testing

• Unit Tests: Write unit tests to verify the correctness of individual components.

• Integration Tests: Write integration tests to ensure that the different components work together properly.

• Security Tests: Conduct security tests to identify potential vulnerabilities.

• Fuzzing: Use fuzzing techniques to test the robustness of the wallet software.

IX. Deployment

• Packaging: Package the wallet software for distribution. This could be a binary executable or a package for the Fedora Linux package manager (DNF).

• Documentation: Provide clear and concise documentation for users.

• Distribution: Distribute the wallet software through a trusted channel.

X. Example Code Snippets

Due to the size and complexity of this project, providing complete code snippets is not feasible. However, here are some example code snippets to illustrate the key concepts:

(See snippets above)

Important Notes:

• Constant Evolution: The field of quantum-resistant cryptography is constantly evolving. Stay up-to-date with the latest research and recommendations.

• Complexity of zk-SNARKs: zk-SNARKs require a deep understanding of cryptography and circuit design.

• Security is Paramount: Security should be the top priority throughout the entire development process.

This detailed guideline should give you a solid foundation for creating your quantum-resistant digital wallet on Fedora Linux Core 41. Good luck with your project! Remember, this is a complex undertaking and requires significant expertise and effort. Don't hesitate to seek expert assistance if needed.
