Default 21 PoW works, but if I change anything in the settings, posting doesn't work. It tries to connect to http://localhost:42068/powgen and fails.

@npub13az…8m54 could getwired have a page with the highest-PoW likes in the last 24h? So instead of showing count(likes), it shows count(pow(like))? Or have a toggle to switch between them?
Everyone compains likes are meaningless (see "onlyzaps" feature on Damus).
But IMO PoW engagement (likes, reposts, replies) are even better than "zaps", because you cannot fake it like with wash-zaps.

Agree, nothing is set in stone.
A good protocol can be ignored for years, but can suddenly catch on for a random reason: #note164g…g9u3
IMO nostr will sooner or later turn to PoW, so the more methods for using it and buying it, the better.

Yes it solves that problem, but adds trust in the mint.
You're not receiving sats per se, you're receiving cashu, which is redeemable to sats via the mint.

AFAIK Blixt and Phoenix do the plain anonymous "pay to LN Address flow", which doesn't touch nostr.

2023-11-30 20:36:31

- reply

I think it relies on the privacy-invazive zap flow, meaning your LN tip leaves traces in nostr events of who sent the sats.
Otherwise it wouldn't know the npub of the sender, e.g. who to send the DM to with the token.

Hey @npub1zfs…w445 , it was great to see you add NWC so early on. I used it extensively to test some of my own NWC implementations.
Tried to use it now and I see it on a screen that links it to zaps: "Nostr Wallet Connect / Send zaps easily with Bitcoin Lightning"
Is there a way to use NWC in Lume to just send LN tips? e.g. without the privacy invasive zap overhead?

2023-11-29 21:20:47

I agree, its the relays who face the brunt of the spam, so they have to deal with it the most.
IMO there are 2 ways to go about it:
1) Paid relays. This means only members can post. This means free relays are left behind, vulnerable to spam attacks. Which is a disaster for onboarding, as new users will basically have to pay to post on nostr.
2) PoW. Just like Tor is using PoW to defend against spam attacks, relays can dynamically ask for PoW for new events, or even for subscriptions. Higher relay load = higher PoW needed. PoW means constant work for spammers and only occasional work for honest posters. If you look at the bigger picture, it exponentially harder for spammers to attack multiple PoW relays at once. This is good news for honest users, who will likely be using a few relays: if some relays are under attack, the others are likely not, so you can still post at a low or no PoW threshold.
Either sats or mining, it comes down to a provable cost. At the end of the day, sats are PoW are interchangeable. You can buy PoW with sats, or sell PoW for sats.
TL;DR: With PoW all relays, including the free ones, have a chance to ward off spam atacks.

Or pay for PoW from mobile, for any event: #note1qqq…8g0d
Yes scammers have botnets, but they'll only use them when it's economically viable. But if it's economically viable to mine PoW for spam, then:
1) it's also profitable for honest miners to sell PoW (e.g. in a marketplace), because there is now economic demand for PoW
2) relays can add a number of cheap defenses that makes spamming exponentially more difficult, even for spammers with botnets: for example, AUTH with PoW (one time per session), then post without PoW

Currently testing it with Gossip : https://github.com/ok300/gossip/tree/ok300-powwow-client (cc @npub1acg…p35c). This lets my Gossip client buy PoW for every event (note, repost, etc). Very rudimentary, but good enough as proof of concept.

2023-11-23 19:27:57

Looking for testers or feedback on PoW WoW.
It's a protocol to buy PoW for any notes, or to sell hashrate.
The idea is: clients can start "shopping" for PoW for any event they create. They say how much PoW they want, how fast, and how much they're willing to pay. Providers mine the PoW and send it over together with an invoice. The PoW is packaged in such a way that it's only usable after the invoice is paid (e.g. the preimage is known). Long story short, after the client pays, they can "open" (unblind) the PoW, add it to their event, and broadcast it right away.
To see it in action: https://lab.oak-node.net/powwow/uv/demo/powwow_20231123.mp4
For details see https://oak-node.net/book/powwow/
Any feedback or questions, let me know! Thanks.

I played with a prototype for this a while back: https://oak-node.net/doc/trunk/doc/ons/ons-4.md
If there's any service provider interested, LMK and I could revive it.
Essentially comes down to:
- offer a LN address where customers can easily pay to: user_id@service_provider.com
- the LNURL-pay endpoint creates invoices with the user ID in the description
- in effect, any payment to that LN Address results in an invoice with the user's ID in the description
- user can setup a recurring payment (or stop paying, or change the payment amount) anytime, using any recurring payment solution
- service provider needs a simple piece of software that can lookup current user balance based on paid invoices with that User ID as description
- the service can stop or resume, based on the user account balance

For the fully non-custodial version of this, see Oak Node.

I think he means relays who don't play by the rules.
A malicious relay coud:
- send the same message(s) multiple times
- send extra messages that don't match the filters
- do this both for stored events (pre EOSE) and for streamed events (post EOSE)
IMO its a viable attack vector, because clients have less resources so by doing the above, a relay could DoS a client.
Even if unexpected events are "filtered out" by the client before showing them to the user, the client still presumably verifies they're valid events, and signature verification is quite intense. So unexpected large events are also an attack vector, they can hit the client CPU hard.
Nostr SDKs used in clients could defend against most of this by
- only returning events that match the subscription filters
- only validating if an event is valid (signature) if the above is true
- not processing and returning events that have already been seen before (much harder to do)
cc @npub1drv…seet
Probably not a concern now, because Nostr is small.
(Another defence for clients is to use a semi-trusted relay aggregator like Wine or caching service like Primal)

cashu-lnurl looks like a quick and simple way to do offline receive. Though you have to trust the provider. And you get the sats as cashus.

Here's a scenario: a service provider lets you run a Nostr bot. It has its own keys, but it can watch for events of your main Nostr keys and react to them with configurable "if this then that" rules.
For example, "if I reply with a smiley face :) to a note from my main account, then bot will send 1000 sats to the author of that note"
"If I reply with two smileys, send 10k sats"
"If I like and repost a note => send 50k sats"

In addition, you don't even need the app to have the "send sats" feature, in order to send the sats.

You click like? That could tell the bot "send this profile 1000 sats".
You like and repost something? That could mean "send 50k".

Use a different app, like Amethyst or Onyx. If they can use the NWC connecting string fine, then its a problem with Damus.
If they also fail to parse it or use it, its a problem with the connection string. Check if there are weird characters in the connection string, like slash after the relay URL, or extra spaces / commas.

Not when actions and events can have multiple, unknown meanings.
A like in the app can cause your bot to transfer 10k sats, in the background, to the note author.
Repost + like combo could mean "send 50k sats".
Replying with "Love it, your art has inspired me to grow 100x" could be code-word for telling the bot to send 100k sats.
Etc etc
