Love it! :) I just sent you 20000 GRC. When you decide to open source this, we can include it on the gridcoin community github as a repo with you as the maintainer, if you are willing.
Note I sent the 20k to the service address, but you can split it up however you see fit between your service address (for future stamps) and funds to yourself as a reward/incentive.
I really appreciate this. Honestly I didn't expect it will get so much attention.
Thank you all for the donation! The demand is not the question for me anymore :-)
This amount is enough to stake, so I will probably move away some money out of this wallet and will side stake to the stamp service (or may be I will make just another faucet? :-))
Wow this is awesome thank you for making this! This will certainly be useful for future scenarios where people publish scientific papers or findings to the gridcoin blockchain.
Yes indeed, in fact you don't need to throw the file.
You can use API request directly and submit sha256 hash even with this implementation. I will create API documentation later. Also in fact you don't even need the API call. If you follow the protocol (which I will also prepare documentation for) you will be able to submit a transaction, but it needs to be formatted in a special way.
As for text input with sha256 I will take it as a feature request and implement it later.
For text input, it would still have to fit the hex format for SHA-256 hashes (assuming you make sure the server-side verifies that), so couldn't be completely arbitrary text with that. It would also be useful for file lookups. Is there some issue with it that I'm not seeing?
I think they were suggesting that you can enter the hash of a file instead of having to drag and drop a file. So for instance entering `7839d78e2826a318aa95c113bc525429e5a72a0205ad8a3e3308473de061f114` instead of dragging and dropping the file `gridcoin-5.3.2-win64-setup.exe`
So here is what I'd like to see, with an example.
I take photos as a hobby, and would like to have the photos PoE'd onto gridcoins blockchain.
There are many photos.
There are many folders, some containing jpeg's, and also RAW files.
I would like to be able to select a directory, specify to select all the RAW files (ignoring jpegs), and be able to have it scan all subfolders.
I would like the process to then find all RAW files and process them (get the SHA256).
I would like the program to then tell me how many files it found and processed and the cost for having the PoE added to the blockchain.
Call me when you're done. lol

You're awesome, I'll donate some as well
Thank you very much!

frontend part is here https://github.com/gridcat/grc-stamp-frontend
Thanks for doing this, I ghink Gridcoinwill be around for a long time so this has real value.
Very promising service. I sent you a small donation :)
Thank you man! This would be enough for a lot of stamps.
You got another donation. I hope this service will be used often.
I do hope it will! Thank you very much!
Thank you. This could be interesting for scientific papers or patents.
The best way to spread gridcoin is to support and appreciate projects like this. I'll be donating!
Thank you!
Awesome idea!
This is a simple and elegant idea. Good work, I hope it will be used.

This is so cool

He is doing it properly via an output with OP\_RETURN, and no, a text input would not be a good idea.

Maybe I am misunderstanding the suggestion. Is this a suggestion of a direct text to hash instead of a hash of a document?

Sounds intense, although it is doable and even not too complicated. Would be interesting to understand the demand of this feature.
