Lightning Addresses for EVERYONE on Hive!
WORKING AGAIN!
I think it's all back to normal.... whatever normal actually is....
Earlier today 2022-05-20:
Coingeck's @coingecko 's API is still not working and I can't restart without it. Following this I will obviously work on adding another price service so I'm better prepared for this kind of thing.... living and learning!
Overnight Coingecko's API started going wrong and so I've got to clean up some stuff, all should be working again soon I hope.
You know that thing on Twitter where people (mostly) in the US can receive BTC Lightning tips direct through Twitter?
Well now literally EVERY ACCOUNT ON HIVE can receive Lightning tips!
If you like my work on bridging Lightning and Hive, please vote for my continuation proposal:

You heard it right. Your very own human memorable Lightning Address looks just like this (yes it does look just like an email address):
[email protected]
Just replace brianoflondon with your own Hive account name. Any BTC lightning sent to that address will end up as Hive in your Hive account.
You can also get yourself a QR code like the one I have at the bottom of the page.
This link will give you a QR code: just replace my hive account name with your own.
https://v4v.app/v1/lnurlp/qrcode/brianoflondon
You can save that image and put it anywhere.
And a special shout out to all Hive Devs: you can add "tip with Lightning" buttons to any Hive UI. You just need to call the api to generate the QR code (you can even cache this, it doesn't change!).
Demo
I've sped up the typing part but the rest of this is real speed. The wallet I'm using here is Breez which is a non-custodial wallet (meaning I really do hold the keys). There are custodial wallets which might shave a few seconds off the Lightning sending time.
How it works
Behind the scenes there is quite a lot going on to make this happen.
As I've written extensively before, Lightning is not a blockchain based crypto system. Lightning can only be received by a Lightning Node which is online and working 24/7 and which has "channels" open to the rest of the Lightning Network.
So in order for you to "receive" Lightning on a static address, just as you can receive Hive on your username or BTC on an address you can generate, things get interesting.
LNURL
What Lightning needed was a way to have a pointer to something on the web which could then generate a Lightning Invoice as a way to receive funds. I kind of built this from scratch myself in order for my v4v.app system to receive Hive and send Lightning: behind the scenes I don't really just receive Lightning, I generate an invoice which a mobile wallet can pay.
DIY was the way I learned
Having built this all from scratch myself, I then realised I had built most of the components I would need to implement something which has been growing in adoption on the Lightning Side: Lightning Addresses. There's a fancy website to tell you all about this and it gives you dozens of ways to grab a Lightning Address but almost all are custodial.
There is a way to set this up with your own node but it's seriously tedious work (here's a 20 min video for you to plough through.
The Flow
Part 1 flow
The background for what is going on here is in this Github repo: LNURL RFC. I'm specifically making use of LUD-01, LUD-06 and LUD-12
- LUD-01: Base LNURL encoding and decoding
- LUD-06: payRequest base spec
- LUD-12: Comments in payRequest.
When a compatible Lightning wallet scans the QR Code I produce or a user types an address like [email protected] into a compatible wallet they are presented with a screen like this screen from Zeus. There's a visual reminder of the destination (my avatar), space to enter an amount between 1,000 and 100,000 Sats and space for an optional comment.
Part 1 technical
The Lightning Address is encoded in the QR Code as a BECH32 string and actually looks like this:
lightning:LNURL1DP68GURN8GHJ7A35WCHXZURS9UH8WETVDSKKKMN0WAHZ7MRWW4EXCUP0VFEXJCTWDANXCMMWV3HKU64WYHS
The lightning: prefix is mostly to help Mobile apps route these strings. On my iPhone, the Breez app grabs these strings automatically if the camera sees a QR code with this encoding. On Android the same thing happens but I believe you have the option to chose which app takes over.
The Lightning app then sends a GET request to the URL encoded in that string which is actually this:
https://v4v.app/.well-known/lnurlp/brianoflondon (you can click on it, you'll get some JSON).
If you manually type [email protected] into a Lightning wallet as an address it just reorganizes that to make the same call.
That GET request returns a JSON which looks like something like this:
{
"tag": "payRequest",
"callback": "https://v4v.app/v1/lnurlp/callback/brianoflondon?no_image=true",
"minSendable": 1000000,
"maxSendable": 100000000,
"metadata": "[[\"text/plain\", \"v4v.app Lightning to Hive @brianoflondon\"], [\"text/identifier\", \"[email protected]\"], [\"text/long-desc\", \"Sending Lightning to Hive account: @brianoflondon\"]]",
"commentAllowed": 1000
}
However I've actually excluded a big chunk of data from the "metadata" field because an encoded version of the Hive avatar is sent in there as well.
Part 2 flow
The user can now be shown a range for the amount to send and an image to help identify where the payment is going: that's where I use the Hive avatar. The user can then add a comment and hit send, there will be one more confirmation and then the sats will be sent.
Part 2 technical
The wallet app can now call the "callback" address with the parameters set by the user. When that happens my API generates a unique invoice specifically for this payment in the form of another BECH32 encoded string. This is the "regular" Lightning way of making exchanges of value.
Once the Wallet receives that invoice, it pays it.
Part 3 Hive
From here on in the rest of my @v4vapp apparatus takes over. It watches incoming payments to my Lightning node and acts on them based on various metadata in the comment field and embedded in the Invoice itself (which my software generated in part 2 above). I receive the sats and immediately make a conversion to Hive and send the Hive out. That bit is generally quicker than the Lightning side.

This looks incredible, although reading all that confuses me, there are still many things I don't understand about Hive and the crypto world, I don't know much.
But what you show here looks awesome. I have to read it again in greater detail. Understanding how the funds can get to my Hive account, but from the side of the person giving the advice I don't quite understand that part of what to do. Maybe I read it too fast or got confused by so many things I don't understand. But it looks super fabulous, thank you very much @brianoflondon 😎

You need to try it once more Nathan. Let's see if it works again.
This is exactly why I put the avatar in the middle of these :-) Very important part of the plan!
So there's only one time we can generate this unique QR??
Posted Using LeoFinance Beta
You can generate it as much as you like but it shouldn't change. Behind the scenes it's just a complicated way to encode this address:
https://v4v.app/.well-known/lnurlp/finguru?no_image=false
So unless I change something, that doesn't really need to change so the QR code remains static.
Got it. Just to confirm one last time, my QR code will not change even if I change my DP?
Posted Using LeoFinance Beta
i was wondering this too... if DP means profile pic that is...
no worries, just saw below. So each time you generate a new qr code it updates your profile pic in the centre. Thats cool. Proposal supported btw. amazing work

I couldn't get [email protected] to work with Strike. However, invoicing through v4v does work with Strike. I'll have to play with another Lightning wallet.
This is the bridge to HIVE I have been waiting for. I look forward to seeing the platform scale. Although, this alone is huge.
amazing, thanks!

This is freaking EPIC!!! We need got all use these addresses on Twitter for our usernames! Changing mine now actually!
Question… How would we approve the invoice on our end… For instance I attempted to send from Cash app and they require an invoice approval.
I am going to try again from my Blue wallet which is non custodial to see how it reacts there.
Just something I ran into…
Can this (or anything similar) be used by exchanges as a transfer method, when people buy/sell Hive and/or Hive Dollars (HBD)?
Amazing news!

So by using the Lightning address you can buy Hive with bitcoin without using an exchange, and it goes straight to your Hive account?
Does it work in reverse? Say you send Hive to the Lightning node and receive satoshis?
This is pretty cool, I am curious how much it ends up getting used.
Is there a % cut from what is tipped outside of transaction fees?
I'm taking 200 sats + 0.8% per transaction. That's about as low as I think it should be. I'm taking rates from Coingeko.
Man....This is just awesome on so many levels!
Thank you for all the hard work you put into this community. Appreciate you sir!

Hello Brian, there seems to be a bug in your code. I received multiple HIVE payments for a single lightning transmission.
Yes! Coingeko's API has broken and this has caused my code to malfunction. I've turned everything off right now and will try to work out what's going on. and fix.
I send you the Hive I received later
Thank you, i'm still trying to figure out what happened. Did you also send me (separately) a payment direct to me as lightning?
Yes, i sent you two Times 1000 sats.
Don't send me anything back yet, there was a huge problem at my end caused by @coingecko 's API not working (and me not anticipating that failure properly).
I'll work through all the problems and let you know. I think you probably got around $5 worth of Hive more than you should but it will take me a while to untangle this and Coingecko's price feed is still not working anyway.
5 years this has been happening to me, it started here, around people that are still here. Homeland security has done nothing at all, they are not here to protect us. Dont we pay them to stop shit like this? The NSA, CIA, FBI, Police and our Government has done nothing. Just like they did with the Havana Syndrome, nothing. Patriot Act my ass. The American government is completely incompetent. The NSA should be taken over by the military and contained Immediately for investigation. I bet we can get to the sources of V2K and RNM then. https://peakd.com/gangstalking/@acousticpulses/electronic-terrorism-and-gaslighting--if-you-downvote-this-post-you-are-part-of-the-problem

Greetings friend @brianoflondon pleased to say hello. I have been testing the lightning bridge, trying to send some satoshis to my wallet Tippin.me but there has been no way for the application to take the invoice. In the image you can see the message it gives me every time I try.
Now, I sent satoshis to my Hive account and this transaction was carried out without problems and very quickly. My question: what could be happening? Are there any restrictions with this wallet or something like that? Or am I doing it wrong? I know how to thank you very much for your support and help. Greetings.
You’re right my code has a problem with Tippin. I’ll look at this today and hopefully get it working. Thanks for finding this!
Fixed it and it should be working with Tippin now. I sent you 2000 sats :-)

@brianoflondon, huge respects for your continuous and tireless work!!
I've tried just now to send some BTC to Hive, from a "Chivo" wallet, and it seems to not be compatible with my v4v.app LN address (nor its QR code version). It does recognize the address - a green check shows up when I type it - but when pressing the "next" button, nothing happens, contrarily to when the recipient is a LN contact added through his phone number.
Have you received feedback from "Strike" users, indicating that it does work on that app?
Wow, this is some amazing work Brian. I'll keep tabs on this project, your work will be supported. Keep going mate!!!
This is absolutely amazing work! Thank you so much for your brilliant contribution to our glorious Hive Blockchain!
Show me normal and I'll give you a some HIVE.

Posted Using LeoFinance Beta
What about doing it in the opposite direction, say Hive to BTC?
Done. V4v.app you send Hive to pay to Lightning.
This is amazing @brianoflondon! I can't imagine how tedious and how long it must have taken you to do all of the coding for this!
