Nostr Web Client

We don't want users to have only one ID. For example, when joining a group chat with mostly strangers, we recommend using a new ID. nostr:note1kgha0g0rt6ywkcx5xzj6s788ycjpwygre7q92szaek5e8g22p85qaatrwc

Hello!

Will it be possible to send pictures via Keychat?

Will it be possible, when replacing a smartphone, to take correspondence from Keychat with me, as is done in Simplex and 0xChat?

You can settle Discreet Log Contracts with Chaumian ECash!

nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg and other ecash devs: Do you think this would make a candidate NUT extension on the cashu spec?

Feedback appreciated 😎

Interesting idea, eCash is good for such things. However, is the development of tests for the integrity of mints and the resistance of mints to theft of funds by their owners on the horizon?

To avoid tracking, do you need to change addresses manually every day or is this done automatically when you send a message?

The Introduction of Keychat

Keychat is a chat app, built on Bitcoin ecash, Nostr protocol and Signal protocol.

Keychat is inspired by the postal system — stamps, post offices, letters.

Keychat uses Bitcoin ecash as stamps and Nostr relays as post offices.

Senders send messages stamped with Bitcoin ecash to Nostr relays. The Nostr relays collect the Bitcoin ecash, then deliver messages to receivers.

Unlike the centralized postal system, Keychat can use multiple Bitcoin ecash issuers and Nostr relays, each maintained by distinct operators.

Keychat uses Signal protocol to ensure message encryption security and meta-data privacy.

The content of the letter can be exposed easily by opening the envelope. Keychat messages are end-to-end encrypted via Signal protocol, with a unique encryption key generated for each message. Only the sender and receiver can decrypt the message.

The addresses of both parties on the envelope can be tracked. In theory, this problem is solved if they change addresses daily. So Keychat reuses Signal protocol to update sending and receiving addresses for nearly every message.

Like the postal system, Keychat requires no registration. Users just generate Nostr keys as ID.

To prevent the relay from knowing who is sending messages to whom, there is NIP-17. And there is NIP-104.

It confuses me that in your client, the relay sees participants in communication.

Don't think that I'm against paid messages, I realized that they are needed.

The reason Keychat is so adamant about using Bitcoin ecash as stamps is that free services are unsustainable.

A blog post by Signal from last year discusses the costs and losses involved in running Signal.

"We estimate that by 2025, Signal will require approximately $50 million dollars a year to operate.”

This is what you need to write about on your website, you need to educate people.

Keychat

Because relay operators need to pay for server-related expenses. SimpleX relay operators also need to pay server-related expenses.

You didn’t write about this on your website, you didn’t say why I should send paid messages.

I'm not outraged, I just want people to understand what incentive they might have to use your program.
