Nostr stores all your follows in one big list: https://nips.nostr.com/2
The client has to load the existing follow list, add on the new follow, and then save the list back. Sometimes the client messes up loading the existing list and nukes all your previous follows.
I don't know why they chose to have all follows in one blob rather than making them separate items.

To play devils advocate - What do RSS and Nostr give you as an artist that you can't get anywhere else? Why is it worth investing your limited amount of time here rather than existing platforms with a wider audience reach?
What does this give listeners that they can't get on the big platforms? Why is it worth using this over SoundCloud or Spotify?
For me, I like directly supporting artists and finding good music that I can't find or that gets buried by overproduced music on the big platforms. I like the community of artists we have and the ability to have a direct connection with them with nobody in between. I also like using Bitcoin as money as it was originally intended to be.
I also think this is still very technical and nerdy and most people aren't going to get it. You open up Primal and all of the top notes are about Bitcoin and Nostr and none of them are about music. How does a new user find music here? Most Nostr apps still emulate the Twitter firehose model when maybe a reddit-style community system would be better?

I guess I confused blips and bolts. But it has been around for 5 years now and is supported by all the major lightning implementations.

It's not the applications that are the issue. Most of them already support lightning addresses and keysend. The issue is that the majority (95%) of feeds still use keysend addresses and anyone using a lightning address-only wallet can't send payments to a keysend address.
Keysend was ratified as bLIP-003 and is part of the Lightning Network protocol: https://github.com/lightning/blips/blob/master/blip-0003.md . It's true that LNURL is preferred nowadays, but keysend is still perfectly valid.
For LND, you use the same SendPaymentV2 call that you use to pay invoices to pay keysend: https://github.com/Podcastindex-org/helipad/blob/main/src/lightning.rs#L74-L134 . The only difference is you provide it with the node address, hash, and preimage rather than the invoice (payment_request). I would be happy to implement it if your software was open source.

NWC is a protocol that connects apps to wallets and supports paying invoices and paying keysend. Wallets can choose to support one or the other or preferably both.
https://github.com/nostr-protocol/nips/blob/master/47.md#pay_invoice
https://github.com/nostr-protocol/nips/blob/master/47.md#pay_keysend
The reason we prefer keysend is because it doesn't require a bunch of extra LNURL/HTTP infrastructure to make it work. Your wallet pays another wallet directly on the Lightning Network and that's it.

CoinOs's implementation is NWC-only as far as I know. Here's the relevant (Core Lightning) code from their repo:
https://github.com/coinos/coinos-server/blob/master/lib/nwc.ts#L293-L330
https://github.com/coinos/coinos-server/blob/master/lib/payments.ts#L499-L534
Here's Alby Hub's LND implementation:
https://github.com/getAlby/hub/blob/master/nip47/controllers/pay_keysend_controller.go
https://github.com/getAlby/hub/blob/master/lnclient/lnd/lnd.go#L497-L589
The main ones that support NWC right now are v4vmusic.com, Castamatic, and StableKraft.app. Podverse is adding NWC to their 2.0 version. The other apps have historically used the Alby API directly, but we're working to get each of them to adopt NWC.

2026-05-06 04:33:34 CEST

Would you consider implementing the ability to send a keysend payment from Rizful? A lot of the Podcasting 2.0 music and podcast feeds still use keysend and it would be great to use your NWC wallet with v4vmusic.com, Castamatic, or any of the other podcast/music apps.
I understand the issues with not wanting to implement receiving keysend payments, but sending keysend payments is pretty trivial. CoinOS is doing a similar thing where their NWC implementation supports send but not receive.

I think Nostr is great for discovery. The only method we have for RSS right now is a centralized database called the Podcast Index. We could use Nostr relays to decentralize that index and provide a way to share music and podcasts with friends and others.
I don't think Nostr is suited for hosting content. RSS is a simple text file that you can host on any webserver along with your MP3s. Webservers are very good at serving small static files like RSS at scale and can do 10k requests/sec out of the box. Compare that to Nostr, which can take multiple seconds to find a single piece of content spread across multiple relays.
The problem with RSS is the user interface. Many people want a simple user interface for it and don't want to learn how it actually works. We do have https://musicsideproject.com and https://sovereignfeeds.com that let you fill out a form to generate an RSS file. You still need a place to put that file and some people don't want to learn how to upload files to webservers either.
I think there's a good opportunity to combine the strengths of each technology and build something great. You could build a Nostr app that uses Nostr relays for podcast/music discovery, uses RSS to build podcast/music feeds, and uses Blossom to host the RSS feed and MP3s on a webserver for you.

I would invite anyone who wants to help to check out some of the vibe coding tools that are now available, like Shakespeare, Cursor, Claude, Codex, and Gemini.

They're just standard Lightning nodes that use Keysend rather than Lightning Address/LNURL/Invoices to receive payments. Most of them (other than Fountain) are self-hosted and self-custodied rather than being hosted by a custodial wallet.
Both Keysend and LNURL are ways to get around Lighting's requirement that a sender needs to ask the recipient to generate an invoice before they can pay them. There's no way to send a "spontaneous payment" in standard Lightning.
Keysend works by sending the payment with an empty invoice. The recipient's node just receives the sats and ignores the fact that there's no invoice attached. The sender uses the node's public key to send the recipient sats via the Lightning network.
LNURL works by putting a publicly-accessible webserver in front of the recipient's node who's only job is to generate invoices for people who ask for them. The sender uses the recipient's Lightning Address to look up the webserver, sends a request to the LNURL callback, and gets an invoice back. They then can pay that invoice on the Lightning network.
V4V nodes chose keysend because it's simpler and requires no additional lookups or servers in the middle of the payment process. You just send a payment from your node to the recipient's node through the Lightning network and that's it.
Wallet providers, including most of the ones the Nostr folks use, chose LNURL and ignored keysend entirely, which is why many here are unfamiliar with it.

That's the logical alternative to the LNURL payment flow:
Instead of: Payer -> HTTP/LNURLp -> Recipient
Do: Payer -> Nostr Relay (Hopefully not Cloudflared) -> Recipient
Of course if we adopted keysend or BOLT12, the payment flow would be Payer -> Recipient without any middlemen.

We originally chose keysend because you can send metadata (sender name, total amount before splits, message, podcast, episode, app name, etc) along with payments through the Lightning network. You didn't need any web server or service sitting in the middle.
Keysend also just lets you send a payment without requiring the other side to generate an invoice first. Most of our feeds have payment splits in them for the podcast hosts, crew, and anyone responsible for putting together a podcast and it's a bit cumbersome to have to generate multiple invoices for every single split.
We've since updated the spec to allow for a Lightning Address to be used in the feed which allows the app to use either keysend or LNURLp depending on what the sending and receiving wallets support.
But we haven't completely figured out how to send the metadata to the recipient since LNURLp doesn't allow the same amount of metadata that keysend does. @npub1v5u…n0v5 solved the issue by posting the metadata as Nostr notes, but some in the community are reluctant to rely on Nostr or don't want their metadata to be publicly available on Nostr.

Yeah lnaddress/lnurlp is what we want to move towards, but the boost metadata issue has been tricky.
Keysend lets you attach arbitrary metadata (TLVs) along with your payment, which is how boosts work right now. The payments and boost metadata arrive directly to your wallet/node without any third-party involvement.
Lnurlp doesn't have the same flexibility and only gives you a 200 character comment field to use, which is too small for our purposes. We basically need a service or api or something to store the metadata for each payment and there's no agreement on how that should work.
Nostr solved this problem by having the lnurlp server post the metadata back to Nostr as a zap receipt whenever receiving a payment. There's still some ambivalence about using Nostr or any third-party service in the podcast world.

2025-09-04 19:25:55 CEST

Unfortunately you have to pick one or the other. Alby and Fountain are basically the only two that support keysend, but they're the two that most podcasters use right now. Other wallets like Strike or Primal only support lnaddress and don't support keysend.
You can look up the keysend info for a person through the well-known url. For example, my well-known ([email protected]) is at https://getalby.com/.well-known/keysend/ericpp . That gives you my lightning node pubkey and a custom key/value for my wallet (basically a wallet id).
You can then use the pubkey, custom key, and custom value to create a valueRecipient tag:
<podcast:valueRecipient name="[email protected]" type="node" address="02c7bb6f29f09d92d40d62d64443b688891259dea324406b4678df6235794f24bf" customKey="696969" customValue="34" split="1"/>

@npub18am…p424 There is a small issue with your feed. The value recipient types should be lnaddress rather than lightning-address: https://sessions.soapbox.pub/rss.xml .
Also, the podcasting world hasn't fully figured out the switch from keysend to lnaddress. So if you want to see boost information (sender name, total unsplit amount, message, etc), you have to use keysend rather than lnaddress. I think Fountain might work regardless since it also posts this info to Nostr?

To be fair, I do think Fountain Premium could be really useful for podcasters to have a source of sustainable monthly income. The amount of donations can vary from episode to episode and it's nice to know you have monthly income that you can rely on.
The only issue I had with your post was calling it V4V. V4V is putting the content out there (value) and asking people to contribute their value back to you in time, talent, or treasure. Putting content behind a paywall and demanding value upfront (even temporarily) is not V4V. Check out value4value.info for more detail.
I think a lot of people on Nostr equate V4V and Zaps/Lighting payments as they same thing, when one is a methodology and the other is just a payment method. People have been doing V4V long before Bitcoin and Lighting even existed.

This isn't value-for-value. Value-for-value is putting your content out there and asking listeners to contribute back whatever value they got out of it in time, talent, or treasure. It's up to the listener to decide how much value they get out of the value you send out. That could be 1 satoshi or 1 million satoshis, that could be artwork or research for the show, or basically anything that is value added back to the show: https://value4value.info/ .
This is the Patreon paywall model, which does work for some podcasters. It's not v4v because you're asking for value upfront and setting both the floor and ceiling (i.e. $5) of the value your listeners to send back. Listeners who don't want to pay $5 will either not listen or find a copy somewhere else. Listeners who would be willing to pay more than $5 will still pay $5 because that is what you asked them to pay.

The ultimate goal of the Podcast Index is to decentralize and to not host anything. They don't want to be the single point of failure that they are right now. The index should instead be hosted by anyone that wants to host it.
