Hello, I want to know budget and times for an app that has the ability to register any document in the blockchain. It will be an application where each company will have its access and will know what hash has been saved and to know that those documents have not been manipulated. I thought it could be a public blockchain or a private Hyperledger Fabric. I do not know very well how to connect the documents to the blockchain in the same app. The app could be consulted by this company or give access to other types of people. I want a simple, friendly interface ... Would this be possible? Android only at this point

Hello Alani, How are you? hope you are doing great. I do not know very well how to connect the documents to the blockchain in the same app. The app could be consulted by this company or give access to other types of people. ==> so if you want that the access to those documents will be private and can be given to any people by a company then it must be based on private blockchain so hyperLedger FABRIC is perfect for this app. I want a simple, friendly interface ... Would this be possible? ==> yes it is possible, we are already developing similar system for one of our client so yes this is possible. So there will be 2 parts of the overall app: 1) Hyperledger fabric, that will act as a backend 2) React Native for Android app that will act as GUI. Please share more details about the app so that we can discuss further! Looking forward for the response! Thanks, Jay

Hello There, I think Hyperledger Fabric will be fine because it has the controlling and security. For your project It will cost of $3000. My price is for networking + chain code + font-end (Ionic2/3). I use Ionic because you will have both for android and ios version. please let me know if you need any live demo. Thanks. Regards, Mamun

Hi I am a Blockchain consultant & my team works in Hypreledger fabric, etherum & corda platforms. We have developed PoC based on the multi-organizational network setup for telecom, travel, banking domain. For this particular engagement with the initial information, I would suggest to use Hyperledger fabric & to manage the file in a secure manner I would recommend to use Inter Planetary File System. The entire project development includes Front end - UX/UI, API layer & chaincode/smart contract. It would take about 2 to 4 weeks for the team of 5 to 8 members depending upon the exact requirement. So I won't be able to provide estimates without the requirements and expectations. Please contact on my number - +91 8588817677 for detailed discussion. Thanks Abhinav Gupta Blockchain Consultant +91 8588817677

Hi, I have experience in building decentralized file storage application, etc and that matches your requirement, the integrity of the files can be maintained and the files been encrypted cannot be Tampered by any other person. One can also allow who can have access to these files. I would prefer using ethereum and IPFS but if you wanna go with private kind of a system then it would make lesser sense as you need multiple companies to have access to it. Not saying it cannot be done but would just make lower sense. No offense. Let me know if I could help you with this project. All the best. Regards, Siddharth
