True Decentralized Messaging

Truly decentralized. Permission-less. End to end encrypted. Cheap!

I learned that this runs on the Kaspa blockchain. I had no idea what that was. Looked into it. It’s a fair launch decentralized upgrade to the bitcoin blockchain called BlockDAG. Basically, it follows the Bitcoin ethos, but is scalable due to the chain restructure allowing for parallel blocks. I’ll definitely be looking into Kaspa.

Yes, it costs a minimal amount of Kaspa to send each message, but the app starts you with 0.1 Kaspa from a community fund for free. This allows you to send almost 6 thousands messages before needed to add to your wallet / account’s Kaspa balance. In other words, by the time you need more Kaspa for more messages, you’ll already know what you are doing. And you can get 1 KAS from US regulated exchanges like Kraken or Uphold. Then just send your Kaspa to your KaChat account. 1 KAS (currently going for 3 cents is enough for ~60k messages at today’s fee rates).

I’ve always been on the search for a messaging app that has no centralized servers. KaChat runs on the Kasia messaging protocol on Kaspa infrastructure, which is fully decentralized. The nodes that run this structure cannot see the messages (minus metadata like Kaspa addresses - but this doesn’t matter if the address generated is not linked to your identity). The message content is encrypted end to end.

I’m getting all my friends on this.

We are looking forward to group chats! Thanks!

Best messaging ever?

Don’t know what to say, check it out! Blows my mind! Kaspa

A modern messaging app, riding on the rails of the Kasparov BlockDAG. I never troughs I’d see the day.
