Phone number? What’s a phone number?

SMS and calls are HTTP Unencrypted. Logged. Interceptable. Plaintext on a carrier server like it’s 1998. We’re building the HTTPS: same number or use an atproto handle 🫨, same plan, E2EE private messenger, builtin spam prevention. The network carries it. Nobody opens it. Launching soon 👀

Encryption doesn't help if the app developer chooses user growth over user privacy & agency! Encrypted communication protocols must be open so users can exit to a safer app. AT Secure Messaging Service built on AT Protocol is the open WhatsApp alternative. #AT-SMS www.nytimes.com/2025/09/08/t...

SIM Swap attack occur because companies continue to foolishly use SMS as a second factor for authentication. @3num.co fixes this by magically turning your phone number into a secure public key. It also encrypts all your communications to protect your privacy. coinfomania.com/zachxbt-sim-...

Digital IDs should not give authorities the ability to track where or when you use it. Today, 3NUM and other privacy advocates are calling on authorities across the world to reject any identity systems that can "phone home." #NoPhoneHome

The reason Voice/SMS is vulnerable to fraud and account takeover is that telco employees “essentially have root access”

☎️ Happy National Telephone Day ☎️ March 10th of 1876, Alexander Graham Bell made the first call to his assistant Watson. We've come far since the first call, but we must still add encryption and metadata privacy to protect our communications from Big Tech and hacker surveillance.

The best way to prevent SIM-swap attacks is to decouple the SIM from the phone number. This is exactly what @3num.co does! www.securityweek.com/t-mobile-cou...

Image if the SMS messages you send were end-to-end encrypted just like Signal? 🛡️🔐 An open protocol to upgrade our telecommunication infrastructure. This is the future we are building! 💪

🚨Telecommunications is unsafe, and it's time for a fix! The Salt Typhoon breach of the US mobile infrastructure from last year is a reminder of how fragile the system is. Let’s explore how 3NUM’s new Bourbon Protocol can revolutionize mobile communication. 🧵👇

13/ Let’s build a safer, more reliable communication system—one that’s designed for the future, not stuck in the past. Are you ready for the revolution? 🔥 #DePIN #MobileRevolution #3NUM

11/ Multiple eSIM support on modern phones means you can have redundancy. If one carrier goes down, your phone can switch to another Internet source, and thanks to DePIN, you’ll stay connected via the Internet for voice and messaging. 📡📶

12/ The future of telecommunications doesn’t depend on a fragile, centralized system. With DePIN, mobile communications can be as resilient as the Internet itself. It’s time to take back control of how we communicate. 💬🔓

9/ But there’s a solution: decouple voice and SMS from the SIM card. Let’s stop relying on SIMs for communication! We need a new DePIN-based Voice & Messaging service that can operate independently of centralized operators. 🔑

10/ With 3NUM, as long as you can access the Internet (even in a disaster with Starlink, for example), you’ll still be able to call and message people. No more reliance on a single carrier’s infrastructure. 🚨🌍 #DePIN #Decentralization

7/ Imagine being in an emergency, having access to the Internet via something like Starlink, but unable to make calls or send texts because your carrier’s system can’t authenticate your SIM. This is why we need a better, decentralized system. 🚀🌐

8/ With 5G and eSIM technology, we're already seeing more data-only scenarios. Think of your SIM as a wallet that transfers “money” (access) to the tower in exchange for service. But that wallet can fail, leaving you without communication when you need it most. 💸📲

5/ This makes mobile carriers a single point of failure for both Internet access and SMS/calls. If they go down—or worse, get hacked—you lose all ability to communicate, even if you’ve got access to free Wi-Fi at a Starbucks. ☕️🚫📞

politico.comChinese hackers used broad telco access to geolocate millions of Americans and record phone callsThe number of telecommunication providers impacted by the massive Salt Typhoon breach is now up to nine, deputy national security adviser for cyber and emerging technology Anne Neuberger confirmed.

6/ In the Salt Typhoon breach, Chinese hackers “gained access to U.S. telecommunications networks in a sweeping cybersecurity breach and were able to use their positioning to geolocate millions of individuals and record phone calls at will” www.politico.com/news/2024/12...

3/ Here's the problem: Privacy and security depend on mobile carriers. When a mobile carrier has an outage, every customer is cut off from the world. You can’t text or make calls, leaving you stranded. When carriers have a breach your private conversations are exposed. 📵💥

4/ Why is mobile still stuck? It’s all about the SIM card. Your SIM tells the network tower that you’re a paying customer. For data, the SIM grants you access to the Internet. For voice and SMS, it still uses the insecure and outdated SS7 protocol. 😱 #SIMSwap #SS7

2/ The Internet was designed to be resilient—even if part of the network goes down, communication can continue. Yet, mobile communications (SMS & voice calls) are still using outdated systems that don't leverage the Internet like most other services today. 🤔

In response to the Salt Typhoon breach of the US mobile infrastructure @3num.co is developing the Bourbon Protocol that breaks free from legacy SMS/voice Our mission is for every Mobile Network Operator to upgrade to this new decentralized end-to-end encrypted protocol🥃👇 medium.com/@3NUMDAO/int...
