2025-06-24: Digital Euro: Progress at the Expense of Freedom & Privacy?

The European Central Bank is actively working on the introduction of the digital euro – a state-issued digital currency designed to complement the existing payment system. While this move is presented as modern and innovative, it’s important to pause and ask a fundamental question: What impact will the digital euro have on our freedom, our privacy – and our ability to choose how we pay?

💸 Cash – Tangible Freedom in Your Pocket

Cash is more than just a payment method. It represents personal freedom, built-in privacy, and one of the last ways to make purchases without leaving a digital trail. With cash, you decide when, where, and how you spend your money – without oversight or restrictions.

And yet, cash is increasingly being marginalized. Discussions about limits on cash payments, withdrawal restrictions, or even calls for its gradual phase-out are becoming more common. This is concerning, because cash serves as a safeguard against surveillance and financial overreach. 🛡️

🏦 What Is the Digital Euro – and What’s the Issue?

The digital euro would be a legal tender in digital form – issued directly by the central bank. Unlike cash, it would not be anonymous, but instead technically traceable by design. Transactions could be tracked, monitored in real time, and even influenced or restricted.

Centralized digital currencies make it technically possible to:

  • ❌ limit spending (by amount, category, or time),
  • 🔒 block or pre-approve transactions,
  • ⏳ apply expiration dates or negative interest rates.

While such features might seem practical in certain scenarios, they also open the door to significant interference in individual financial autonomy. This isn’t about criticizing institutions, but rather about preserving a healthy balance between innovation and civil liberties.

₿ Bitcoin – Digital Sovereignty Without Central Control

In contrast, Bitcoin operates on a fundamentally different principle. It is a decentralized digital monetary system, not controlled by any government or corporation. Transactions are verified by a global network, not a central authority.

Privacy by structure: With Bitcoin, you don’t need a bank account, approval, or to share personal data to send or receive payments. When used correctly, Bitcoin offers a high degree of financial privacy, much like cash – but in a digital, global form. 🌍

✅ Why Bitcoin Makes Sense
  • ⚙️ Decentralized by design: No central authority, no censorship.
  • 🌐 Globally accessible: Anyone with an internet connection can use it.
  • 🕵️ Private in practice: No personal information required.
  • 🔒 Inflation-proof: Bitcoin’s supply is capped at 21 million.
  • 🗽 Independent: No third party can freeze or limit your assets.

Bitcoin isn’t just a digital currency – it’s a tool for freedom and financial independence in the digital age.

🧭 Conclusion: Payment Freedom – Offline and Online

Whether paying with coins at a store or sending a transaction from your phone – you should always be free to choose the payment method that suits you. The digital euro may offer certain conveniences, but it must never replace or restrict access to cash or alternatives like Bitcoin.

💵 Cash must remain a free, anonymous means of payment. And Bitcoin offers its digital counterpart – independent, global, and privacy-respecting.

2025-06-15: Use WhatsApp securely with a Proxy

In an age where data privacy is increasingly important, it’s essential to be aware of your digital footprint. Messaging apps like WhatsApp, operated by Meta (formerly Facebook), collect a wide range of metadata — even though message content is end-to-end encrypted.

Fortunately, there’s a solution for anyone who wants to continue using WhatsApp without exposing their connection details: my free WhatsApp Proxy Service! 🌐🔐

What Does My WhatsApp Proxy Do?

My WhatsApp proxy service acts as an intermediary between your device and WhatsApp’s servers. Instead of connecting directly to Meta’s servers, your data traffic is routed through my proxy. This means:

  • ✉️ Hidden IP Address: WhatsApp (i.e., Meta) no longer sees your real IP address, preventing them from determining your location or internet provider.
  • 🌍 No Geo-Tracking: The detour via proxy makes it nearly impossible to track your location.
  • 🔒 Encrypted Communication: All data is transmitted using SSL encryption.
  • ⛔️ Minimal Metadata: Information about your device, region, or connection time is significantly reduced.
  • 💡 Free and Anonymous: The service is completely free and requires no registration.
How to Set Up the WhatsApp Proxy 📱
  1. Open WhatsApp and tap the three dots in the top right corner (⋮).
  2. Navigate to Settings > Storage and Data > Proxy.
  3. Enable Use Proxy.
  4. Tap on Set up Proxy and enter the following details:
    • Proxy Host: whatsapp.cmdsrv.de or alternatively 128.140.60.104
    • Chat Port: 7001
    • Media Port: 7007
  5. Confirm by tapping the check mark ✅.
  6. It should now display “Connected”.

And that’s it — you’re securely connected via my proxy! 🔐

Why Using a WhatsApp Proxy Makes Sense ❓

Meta makes its money through ads and analytics — not just by what you write, but by tracking when, where, how, and with whom you communicate. Even without accessing your message content, Meta knows when you’re online, who you’re chatting with, and from where.

Conclusion ✅

My WhatsApp Proxy Service offers a simple, effective tool to enhance your digital privacy. No registration, no fees — just real benefits:

⭐ More privacy, less surveillance.

Try it out yourself and feel free to share this information with others who value digital self-determination. 🤝

I am an IT specialist focused on networks and server services. I am happy to assist with technical questions or custom requirements. Feel free to get in touch — inquiries are always welcome.

2025-05-26: Open Source Software: Digital Freedom

Open source software is no longer a niche topic – it forms the backbone of our digital world. Many people are unaware of this, but the majority of computers around the globe already rely on open source technologies. In particular, the internet runs heavily on open source: most web servers operate using the Linux operating system, and countless services and applications – from web browsers to content management systems – are built on open source foundations.

🔍 What Does Open Source Mean?

Open source means that a software’s source code is publicly accessible, modifiable, and free to use. This transparency not only fosters trust but also enables global, collaborative development. Control does not rest with a single company or state – it lies with the community. This prevents users from being locked into expensive subscription models or becoming dependent on individual vendors – a scenario that’s increasingly common with proprietary software.

This issue is strikingly portrayed in the latest season of the series Black Mirror (Season 7, Episode 1): A woman receives a medical chip implant after having a brain tumor removed. The twist? The chip is permanently connected to the provider’s cloud – all data and functionality are processed externally, with nothing stored locally. Without an active subscription, the chip stops working. The software operates on a tiered licensing model with steadily rising costs. Eventually, the woman’s family can no longer afford the increasingly expensive subscription levels – leading to catastrophic consequences.

This dystopian scenario highlights how dangerous it can be when essential technologies are fully controlled by a central provider. It creates a total dependency – both technically and financially. Open source offers a radical alternative: transparent, decentralized, user-controlled, and free.

🧩 Freedom Through Technology

Open source is an expression of digital self-determination. Those who use free software decide for themselves what runs on their devices, what data is shared, and which functions are enabled. This independence is more than just a technical detail – it’s a political statement in an age of digital surveillance, data exploitation, and monopolization.

A particularly powerful example of open source as a vehicle for independence is Bitcoin. Here too, the entire source code is publicly available, every transaction is verifiable, and the system itself is not centrally controlled. The idea of freedom, transparency, and decentralization is central – and would not be possible without open source.

🔐 Security Through Encryption

In an age of widespread digital surveillance, protecting private communication is essential. Open source plays a crucial role here: only with publicly accessible source code can users verify whether a tool is truly secure. Encryption tools such as PGP for email or decentralized messengers like Matrix (with clients like Element) are vital for maintaining privacy and shielding digital conversations from prying eyes.

🤝 A Call to Support Open Source

The benefits of open source are overwhelming: transparency, security, independence, and innovation. But none of this happens automatically. The development and maintenance of free software is often done voluntarily or underfunded. That’s why it’s essential that we not only use open source but actively support it – by contributing to development, reporting bugs, or donating to projects that benefit us all.

Here is a short list of the most famous open source programs:

1. LibreOffice
Free and powerful office suite – alternative to Microsoft Office
🔗 https://www.libreoffice.org/

2. GIMP
Free image editor – comparable to Adobe Photoshop
🔗 https://www.gimp.org/

3. Mozilla Firefox
Secure and fast open-source web browser
🔗 https://www.mozilla.org/firefox/

4. Thunderbird
Email client with calendar and chat support
🔗 https://www.thunderbird.net/

5. VLC Media Player
Versatile media player that supports nearly all formats
🔗 https://www.videolan.org/vlc/

6. Audacity
Audio recording and editing software
🔗 https://www.audacityteam.org/

7. Krita
Professional painting and illustration tool for artists
🔗 https://krita.org/

8. Inkscape
Vector graphics editor – similar to Adobe Illustrator
🔗 https://inkscape.org/

9. KeePassXC
Secure and cross-platform password manager
🔗 https://keepassxc.org/

10. Shotcut
Free, open-source video editor with wide format support
🔗 https://shotcut.org/

✅ Conclusion

In the digital age, open source is not a luxury – it’s a necessity. There is hardly a more powerful tool for freedom, self-determination, and privacy protection. Those who want a free society must also support free software. It’s up to all of us to promote open source – for a digital world that liberates, not controls.

2025-05-17: Anonymous. Secure. Free: TOR Network

Why you should not only use the network, but also support it:

The internet should be a place of freedom — a space where you can inform yourself, communicate, and express your opinion without being constantly watched or controlled. Unfortunately, the reality looks quite different: surveillance, data collection, censorship. That’s where TOR comes in — the “The Onion Router” network. And no, it’s not just for hackers or whistleblowers. TOR is for anyone who wants to protect their privacy online.

🔐 TOR Is Not a Hiding Place for Criminals — It’s a Shield for Citizens

TOR often has a bad reputation because it’s associated with the so-called “dark web.” But that image is misleading. TOR was not created for illegal purposes — it was developed as a tool for ordinary citizens who want to keep their online activity private.

Whether you want to browse anonymously, avoid being tracked by advertisers, or bypass censorship in authoritarian regimes — TOR gives you the ability to move through the internet securely and without being watched.

🕵️‍♂️ Snowden, Assange, and the Reality of Mass Surveillance

You may remember Edward Snowden, who revealed in 2013 how extensively the NSA and other intelligence agencies are monitoring people around the world. Or Julian Assange, who, through WikiLeaks, published confidential documents exposing war crimes and corruption.

Both men used secure, anonymous communication methods — including TOR — to protect their sources and themselves. Without such tools, many of these truths would have remained hidden. TOR is not just a piece of software — it’s a symbol of transparency, accountability, and freedom of information.

⚙️ How You Can Support TOR — By Running a Relay

TOR relies on its users to stay strong. Especially important are Middle Relays — the servers that forward encrypted traffic through the network. The more of these relays exist, the faster, more stable, and more secure the entire system becomes.

The good news: Running a relay is technically simple, inexpensive, and has a big impact — for you and for millions of users around the globe.

I have provided a corresponding tutorial for your own Linux server here for free:

https://it-service-commander.de/en/tutorials-2/docker/install-tor-server-in-a-docker-container-on-your-vps/

🧭 Digital Freedom Is Not a Given

Data retention laws, chat control, constant tracking — these are not just buzzwords. They represent real threats to civil liberties. Both governments and corporations are collecting data at a scale that would have seemed impossible just a few years ago.

Privacy is not a luxury — it is a fundamental digital right. And now, more than ever, it needs to be defended.

✅ Conclusion

TOR is not a criminal hiding place, but a protective tool for free speech, journalism, and digital self-determination.

If you use TOR, you protect your own data.
If you actively support TOR, for example by running a relay, you help make the internet a freer and safer place — for everyone.

Real freedom begins with digital responsibility — and that’s in your hands.

2025-04-30: Avoid Port Forwarding – Use VPN Instead

🌐 In an increasingly interconnected world, many people want secure access to their home network from anywhere. However, significant security risks exist, especially if you simply open ports on your router. A better alternative is using VPN technologies like WireGuard or OpenVPN.

VPN stands for “Virtual Private Network” and refers to a secure connection that encrypts your internet traffic and routes it through a protected tunnel between your device and the network. This keeps your data safe from prying eyes and ensures that only authorized users gain access.

⚠️ Risks of Port Forwarding

Port forwarding on a router may initially seem like a simple solution for accessing NAS devices, smart home systems, or surveillance cameras remotely. However, each open port creates a potential entry point for cybercriminals:

  • 🔓 Open Attack Surface: Every forwarded port can be discovered and attacked from the outside. Hackers and automated scripts actively look for open ports and vulnerabilities.
  • 🔍 Lack of Encryption: Without additional security measures, data traffic usually remains unencrypted, making sensitive information easily readable.
  • 🔑 Weak Authentication: Many devices offer insufficient protection or default passwords that can easily be compromised.

✅ Benefits of WireGuard and OpenVPN

Instead of directly forwarding ports, you should use VPN solutions like WireGuard or OpenVPN, which offer numerous advantages:

  • 🔐 Enhanced Security Through Encryption: All data traffic is securely encrypted, making it unreadable to unauthorized parties.
  • 🛡️ Strong Authentication: Only authorized users can access your network, significantly reducing the risk of unauthorized access.
  • 🕵️ Hidden Infrastructure: No directly visible ports from outside, effectively making your devices invisible to automated attacks.

🔗 Why Choose WireGuard or OpenVPN?

Both technologies have proven their reliability:

  • 🚀 WireGuard is lightweight, fast, easy to set up, and offers state-of-the-art cryptography. Ideal for home users looking for straightforward and quick access.
  • ⚙️ OpenVPN has been established for years, is highly flexible, and widely supported. Perfect for complex requirements and professional environments.

📌 Conclusion

If you take your privacy and security seriously, avoid simple port forwarding and instead use proven VPN solutions such as WireGuard or OpenVPN. This ensures your data remains protected and your home network stays safe from attackers.
