Hi guys, I am starting to develop and to write code for Smart Contracts and Blockchain networks. I have seen this very amazing. The project or the idea I´ll share you all now is about Blockchain, I would like programmers and developers to help me with ideas or commenting exactly how they´d do it.

What I am doing now it´s a Blockchain network and its purpose is to secure pdf files in order to give transparence and trust to everyone who´s going to use those documents. For example...

I have "n" documents or files in pdf format, I will upload them in a website but I want to protected or secure them with a Blockchain where they are going to be saved, of course those blocks of the chain should have a hash. When somebody wants to download them, they won´t need to think whether those are fake or real because the can prove them looking at the Blockchain network as Bitcoin network...

If everything from above seems confused, just you can participate commenting how would you relate the Blockchain technology with pdf files, in order to give transparence and trust to the people who´s goind to download it to verify any thing...

Thank you everyone who wants to help in this project and wants to participate commenting, it´s something very challenging (at least for me that I´m starting to develop in these topics).

PSDT: I am using Go language to program Blockchain networks.

Regards!!!

So you are talking about blockchain based file sharing website which is targeted to pdf files. Personally I think current p2p file sharing system is pretty good. I think releasing of your idea will result in following: If people upload pdf files (which can be huge in size, depends on pages and whether it's text or images), size of blockchain will get bigger everytime, also people who run node will have to keep uploaded files and it will take a huge amount of free space.
Btw I think this will be a nice addition to your knowledge in releasing of your project: https://medium.com/@mycoralhealth/code-your-own-blockchain-in-less-than-200-lines-of-go-e296282bcffc

Blockchien can be used in almost any industry. pdf files will not harm such technology. However, it is possible to use it on a larger scale and distribute it to documents of the format: doc, exel.
This is just as a wish. Good luck with your project.

Thank you so much buddy, we are working on it!!! Cheesy

Personally that´s a big challenge because we want to save pdf files in blocks instead of transactions. If anybody who reads this comment or the thread wanna feel challenged and want to meauser their knowledges, welcome all of the help that they can write and share.

Care to share what's the purpose of your blockchain project? To store PDF files for what? For sharing or safe keeping? Don't get me wrong, we encourage people to really take advantage of this technology, but we have file sharing websites around which fits your purposed, IMHO.

Blockchain itself is data connected to each other by encryption. There are some altcoins designed for this purpose, Most notably: Filecoin, read more r/filecoin.
There are some open projects that are designed for this purpose:

 - If I understand your topic correctly, Storj is a developed program for this purpose with a focus on protection.
 - These are some files and codes to read ----> Swarm distributed preimage archive | Github
 - more discussion How Can/Do You Store Files on a Blockchain?

hey, that they are file sharing websites or systems around doesn't mean other people who have interest in that same field can't venture into it anymore, take a look outside Crypto, there are several people doing the same type of business and they all doing fine, and it's also good for you as a buyer as the more the competitions, the better price you get, now, look back into the Crypto space, there are several crypto exchanges where every can buy and sell their BTC, now all this exchanges do almost the same thing but yet, people don't use just one, as all the exchanges don't always offer the same token, so please don't make it look like the guy is doing something that is not likely to succeed if he's serious and put effort and time into it

Thank you for commenting. I understand your point of view, however, I believe that if you want to take advantage completely you need to know it very well. And to know it very well you have to practice with it. Let's suppose this is a kind of practice in order to know very well the technology and to use it as it should be used.  Smiley

Hey, I understand what you mean but there really isn't any need for this I think since normal file sharing works fine, also files would hog up the space fast on nodes, viratotal already does this also

Blockchain Ethereum up to 30 kb
Example:
https://etherscan.io/tx/0x190774d3eab80963fa1f9ffd11b234ddd8f53190e288483f3a38ce17bb920810
PDF file = "data:application/pdf;base64, " + base64EncodedPDF
"Base64" adds 30% to the weight of the file.
If necessary, divide the "Base64" code into several subsequent transactions.
