The main approach for the centralisation risk is that anyone will be able to run the gateway servers for locals around them and we have separated out key signing servers so you can either self host that if you can or that can be decentralised to groups as well.

None of it runs through WhatsApp apis so it’s not obvious what would be going on to figure out to ban it.

If they did ban it your actual account is built on Nostr so it’s portable across whats app / signal / telegram / bitchat / sms
