Just curious. How is this different from audio calls on regular apps like WhatsApp and Telegram? They both have e2e encryption. Also, does it have some type of block for screen/audio recording apps working in the background on one of two phones?

@jorgecerda The main difference is the decentralization, on dPhone you are the real owner of your data, not only the calls, your contacts, your call history etc, all the information also is stored encrypted linked with your Blockstack ID, even without the app you (and only you) have access to those data. The data and everything else works with your Blockstack ID, there is no phone number / SIM card. dPhone is a calling app like many others, the main difference, at least on focus, is the decentralization, the app is built to work almost only on the client-side. The code is open source and anyone can improve it. So I think it looks like more with the Signal than Whatsapp or Telegram.

@jorgecerda About the second question, not yet, but it would be great to have as an additional security feature. Thanks for your input.

@jorgecerda WhatsApp is not really E2E encrypted. All your messages are running through Facebook's servers, and it's already been shown that they collect metadata about your messages. Here is a more in-depth Medium article about Facebook's practices with WhatsApp: https://medium.com/@gzanon/no-en... There's also a few issues with Telegram. It doesn't use E2E encryption by default, if you do turn it on you lose group chats, desktop messenger and your friend has to be online for it to work. They also use their own homemade cryptography despite all the experts saying that's a bad idea. Edward Snowden has called it dangerous and unsafe, and pretty much every security expert will tell you to avoid it if privacy is important to you. The gold standard of free, open source, encrypted communication is currently Signal. Behind that I'd say probably Wire.

How does blockchain help here? Won't that just... store a permanent copy of your call?

@paula_juniper The user identity is stored on the blockchain. So after that, the app will use that blockchain key to encrypt and validate all data. The communication is through P2P, the unique server point is for the push to notify the user about a call, even that push is end to end encrypted.

Hey Product Hunt, 👋 I am the maker of dPhone! dPhone provides a secure way that all user calls are performed directly between users thanks to P2P architecture and blockchain encryption. By using Blockchain-based ID, you know that the person you’re speaking with is who they say they are. Every call is protected by high-grade, authenticated, end-to-end encryption. Would love to hear your questions or feedback, thanks!
