[ANN] bitcoindata.science

[joker_josue]

I would like a service that lets users make a payment request out of an address (and maybe balance) but instead of images it creates links that displays QR codes on a separate page

Won't this make bitcoindata.science a target for hackers? Replacing the address and QR-code by their own could be profitable, which I why I prefer not to rely on third parties for Bitcoin addresses.

Yes, it's always a risk.
He would have to add some kind of verification, that is, a check that the generation of the QR code was done without a third party.
Maybe some kind of letter of guarantee.

It is always risk.

I can add the QRCode genetor to the php backend (reduce the risk of client-side tampering). Then make a front-end verification to confirm that the QR code displayed matches the intended Bitcoin address displayed. This would be a second layer protection.

I think my website is small , I also use cloudflare, which might give some extra security.

Yes, but even though it is small, it may attract the attention of a hacker, who may have the patience to wait for the opportunity. In fact, today it is small, but tomorrow it will not be.

So, if you think about solutions that reduce risk, it's a good place to start.

Bitmover, if it's not too much trouble for you, I would like a service that lets users make a payment request out of an address (and maybe balance) but instead of images it creates links that displays QR codes on a separate page, and when you click a button below it, it opens the payment request in the default wallet.

Hello NotATether.

I have created the requested tool.

https://bitcoindata.science/pay

Although I understand the risks, it was a quite interesting experiment to create it. I created (forked and improved) a bitcoin address validator and the functionality to request payments and amounts in a wallet.

Please take a look.


How it works:

Add the amount and the bitcoin address. You will be requested to make share the URL with your customer.



This is an example of a shareable URL
https://bitcoindata.science/pay?U2FsdGVkX1+TOrtGFoAdVFYq6ZffoYGUb+OHdBd5kT7ngdR79BJXWR1/PtdOF75pWC9d96EeqHplMM7W3PxgOA==




I am a bit worried about people losing money and trying to blame me. I will think about keeping this tool online or not. I would like to listen to your feedback NotATether, as you requested it.

I'd say the URL should be human readable, so the address on your site can be verified against the address posted in the URL. Something like:
https://bitcoindata.science/pay?1BTC+3CrySAp8G1PfvjrYT4HPQhE8MouBKWd9WB
Can you do that?

I knew that one day you would start doing more serious things 

You can do your best in mistake prevention, for example
You need to add a "paste" button where the address is entered. There are many cases where this is useful.
Also, the "copy" button to memorize the payment link.
I'm not sure what type of field you used to enter the Bitcoin address, but when I clicked, I was offered a street address from the browser cache from who knows when. You should probably turn this off because it can also bring unnecessary complications.

As an additional security layer, you can make a small tool to verify what the user has copied. So, immediately on the same side, the field for input and check. The user enters the link he copied, and your script checks if it matches the string from the "share" field

That's a very good idea, and keep things even simpler. I liked it. Done.

Those small details are very boring to do lol... but I agree they are useful.

it is now working!

I changed the name of the field to "bitcoinaddress", I guess you won't see those street recommendations anymore.


i discovered some errors in the address validation script. I will have to find a good one, there are too many checksums :/

Even boring, you fix it quickly

Yes, it's ok now. Every time you surprise me how quickly you react and resolve little things like this.

Even better if any address posted on Bitcointalk gets a QR pop-up on mouseover. But that's something for PowerGlove's patch wish list.

I can easily add this feature in a custom script or in my browser extension.  Would you use it?

If such things are not a problem for you and do not take up too much time, it would certainly be good to have an option.
If there is an option, maybe someone will use it.

I think I saw on another forum that you are not happy with how well your tools are being used. Maybe it's finally time to present yourself better, for example, to move this one or open a new ANN in the service announcements section, where will you consolidate and explain all the features that your site offers.
Certainly, your site has long since become a service and I would say that it is no longer a project under development.
On the second forum as well, your tools are mentioned in several places, but you haven't made a central announcement with all the information about the tools that bitcoindata.science offers

I wouldn't, but I don't like installing browser extensions. Every extension adds to the risk. That's why a forum feature would be cool. Then again, I don't think too many people will use this. If I pay something on my laptop, I use a wallet on my laptop and not on my phone.

It looks OK, but I agree with you that hosting this on your domain would create a risk for you. Since there isn't a big "Pay" button anywhere to be found, nor is there any button that opens a bitcoin:<address> URI in the wallet.

Maybe I should take the source code and host it myself on a subdomain, if that makes you feel better. There are some other minor adjustments I'd like to make in addition to the ones above.

I forgot about that! Just added the "bitcoin:" in the start of the uri

It is already in the QRcode. I added a pay button

What other additional features would you like?

You are free to get the code in the github or request features or even fork it! I am trying to use that plataform more, as it may be useful to get jobs and make a portfolio.

I have created the requested tool.

https://bitcoindata.science/pay

This can be useful tool, but it would be nice from you to say if we can use it offline to generate QR code without internet connection?
I will test later how everything works and if QR codes are compatible with different mobile wallets I have.
I tried entering random characters and it is recognizing that as invalid bitcoin address.

I can easily add this feature in a custom script or in my browser extension.  Would you use it?

What extension is that?
I think releasing it as user script would be better and faster way, that can work with Greasemonkey and Violentmonkey.

Sure it works offline. I could add that information too...

It is compatible with every bitcoin wallet which supports QrCode, as it is BitcoinURI as defined in bip 21

This one.

It is also available as a script.

I think you should add information that pay tool can be used offline similar like iancoleman Mnemonic Code Converter.
This way there are much lower chances of someone attacking and inserting malicious address or QR code instead.

PS
Is it possible to add support for bitcoin Silent Payments in future?
I tried testing with sp1 but I am getting Invalid bitcoin address message.

I will take some time to study about this protocol and figure out how would that work.... This is new stuff to me. I didnt know about it.

You can find more information about it on silentpayments.xyz
This is a great solution to have more privacy and it can be used as a single donation addresses, but wallets just started adding Silent Payment recently, Cake wallet is one good example for mobile and desktop.

Hi @bitmover, thank you for the work done, the site is needed, important and useful. This is primarily a thank you for your work, and secondly:
page /bitcoin-units-converter



for some reason, the height on the flag is set to fixed and not auto, which slightly distorts the dimensions..

width: 26px
height: 26px (change it to auto if you want)



GL,

Been using the Bulk balance checker, and it's working great. Thank you for the project
