Do banking apps specifically target GrapheneOS to block it?

The most common argument that discourages newcomers from installing GrapheneOS is the fear that their banking app might not work. In reality, most banking apps used worldwide work perfectly well, as you can see in the link below.

However, some apps actively block GrapheneOS users. For example, Revolut had a script specifically checking whether the OS running the app was GrapheneOS, and if so, blocking it purely for being GrapheneOS, not for being insecure or outdated. Revolut runs perfectly well on ancient, unsafe devices.

Banned for being GrapheneOS - just because you want a privacy-focused device. While Revolut is a specific case, most other banking apps that don't work fail because they enforce Google Play Integrity checks. But that is GOOGLE'S FAULT.

It is only because Google specifically targets GrapheneOS (which is the safest OS available) with their Play Integrity hardware attestation that we can't have every banking app possible on GrapheneOS.

Google is just mad that you are de-Googling and taking your privacy back.

Don't let them stop you.
De-Google, get GOS.

GOOGLE ANNOUNCES MAJOR QUANTUM COMPUTING BREAKTHROUGH WITH IMPLICATIONS FOR BITCOIN SECURITY

Google Quantum AI researchers have achieved 99.99% logical fidelity in producing “magic states” on the company’s 105-qubit Willow processor, reducing errors by 40x.

The breakthrough, published in Science, addresses one of the biggest engineering bottlenecks preventing quantum computers from scaling to the point where they could threaten Bitcoin’s cryptography.

Earlier this year, Google published research suggesting that breaking Bitcoin’s cryptography could require fewer than 500,000 physical qubits, roughly 20x fewer than previous estimates.

That was an algorithmic breakthrough, demonstrating how an attack could theoretically be performed with fewer resources.

Today’s announcement represents a complementary hardware breakthrough, demonstrating progress toward making the necessary quantum operations reliable and less resource-intensive.

While this does not mean Bitcoin’s cryptography can be broken today, it represents another significant step toward cryptographically relevant quantum computers.

The timeline for a potential quantum threat to Bitcoin remains uncertain, but the case for accelerating Bitcoin’s transition toward quantum-resistant cryptography continues to strengthen.

You can pretty much turn any device into a cold wallet. 🔐

An old smartphone, a Raspberry Pi, even a jailbroken Kindle.

Disconnect it from the internet, strip it down to its essentials, and give it one job: store keys and sign transactions offline.

Your online device builds the transaction.

Your offline device signs it.
Only the signed transaction ever leaves the cold wallet.

No internet. No unnecessary software. Just hardware, cryptography, and your keys.

Anything can become a hardware wallet if you can control the software and isolate the signing process. 🛡️

⚠️ ALERT: iPhone users warned of a potential Safari zero-day that could expose crypto private keys and seed phrases

Security researchers are warning iPhone users about a potential Safari zero-day exploit that could put sensitive data at risk, including cryptocurrency private keys, recovery phrases and information stored in Apple’s Keychain.

The reported attack involves a Safari-based exploit chain that could progress from WebKit/JavaScriptCore memory corruption to sandbox escape and kernel-level access.

The warning reportedly covers iOS versions ranging from 13 to 26.5, although the full range has not been independently confirmed.

If you use an iPhone, check for the latest iOS update and install it as soon as possible.

Avoid opening untrusted links in Safari, especially if you store crypto wallet data on your device.

FLIPPER ONE SENDS DATA 150 KM OVER RADIO WITHOUT INTERNET, TECHNOLOGY COULD BE USED TO SEND BITCOIN TRANSACTIONS

Flipper says its upcoming LoRa module can send messages through a network of radio repeaters without relying on the internet.

In London tests, messages traveled more than 150 km through the MeshCore network.

The same technology could be used for Bitcoin transactions.

A signed Bitcoin transaction is a small piece of data. It could travel over LoRa radio, hop through repeaters and eventually reach a gateway connected to a Bitcoin node, which could broadcast it to the network.

That could give Bitcoin users another way to send transactions when local internet access goes down.

🚨BREAKING: The CLARITY Act has FAILED its Senate procedural vote, short of the 60 votes needed to advance.

The setback stalls the crypto market structure bill but leaves open the possibility of another vote.

[DC DAO @DCDAOxyz]

A vote for CLARITY is a vote for U.S. innovation.

Today’s cloture vote on the CLARITY Act could be the last chance CLARITY has before the House heads into recess. We honor all those who have worked tirelessly to bring us to this day. 🇺🇸

Vote for CLARITY and let's keep building in America.

GrapheneOS is done waiting for Google.

It's replacing Android's old default apps with its own.

Instead of relying on neglected AOSP apps, it's building modern alternatives from scratch.

What's changing:

• New Gallery app
• New Keyboard
• Massive Messaging app overhaul
• Secure Paste that blocks apps from reading your clipboard
• Future RCS without Google Play Services

The goal is simple:

Own the entire privacy stack.

Would you switch to GrapheneOS for features like these?

🚨BREAKING: Someone murdered an entire family in Mexico to steal a Bitcoin hardware wallet reportedly holding $1.5 MILLION.

Jonathan Meléndez, keyboardist of the band Camilo Séptimo, his pregnant wife, their 3-year-old daughter and their housemaid were killed by someone who knew about his holdings stored at home.

Their 6-year-old son survived.

Two suspects were arrested within 12 hours and face up to 70 years per victim.

Violent crypto robberies are surging, with over $30 MILLION stolen through physical attacks on crypto holders in the first half of 2026 alone, per Chainalysis.
