Tweet text: "One of the cool things about Nostr ("Notes and other stuff transmitted by relays", a new decentralized protocol that replaces things like Twitter and Instagram)—beyond censorship resistance—is that you aren't limited to 280 characters." Sounds like Usenet. What will it do about spam?

Proof of work is integrated in the protocol. Either relays or clients can require arbitrary difficulty to relay/show messages. You just drop messages that their hash doesn't start with the required amount of 0s

  That sounds unpromising. Spammers will throw more computational resources than humans are willing to tolerate. They have captcha farms after all. Spammer bot with a server farm (maybe using stolen AWS credentials) will always outcompute a legit user with a mobile phone browser who is only willing to put up with a few seconds of latency.

  It's using SHA256 hashing - so ASICs spammers will easily outcompete handhelds or even desktops. It'll need to upgrade to a more CPU friend hash like RandomX for this to have a chance of working.

It will most likely be overwhelmed by spam and scams, like telegram or like usenet itself (sadly). Until I got fed up and deleted telegram, I was randomly added to at least 1 investment scam promotion group every week.

  Not necessary to delete it, just limit who can add you to the group > The default settings allow for this, so you will want to change them. To do so, open the app and head to Settings -> Privacy and Security -> Groups & Channels and check off My Contacts instead of Everybody. You can also exclude specific contacts (or include specific users who aren't in your contacts). https://www.iphonefaq.org/archives/977460 https://www.iphonefaq.org/archives/977460

    I was getting zero value from the app so it was a joy to delete it tbh. But that's good to hear.

  They claim to defeat spam, but only mention payments as the way. I am not bullish about nostr
