Introduction

Imagine to have Google Drive, where files are stored safely online, but instead to have files on Google server, where Google can see and read your data, the files are store on the blockchain, encrypted, where no ones apart from you can read them.

TRH aims to be a tool able to store your private data and to share data across people without the need to rely on any provider.
TRH removes the middleman from the cloud storage.

How it works

Your files are stored on the blockchain into a serie of transaction originated from the same private key and encrypted with a password.
Key and password can be generated with a passphrase or can be provided indipendently, this gives you the freedom to use your own key and password without rely on the ones generated by TRH. Once stored the files can be downloaded from everywhere, you just need a copy of TRH and your passphrase/address-password, in fact to download data the key is not needed, you only need the address.
This allow a simple way of sharing data across people because you need to share only the pubblic address and the password.
It is possible to have a single key and to upload files with many different passwords, this allows to share different files with different people.

The key must contains enough funds to pay the fees to the miners to mine the transactions generated during the uploading. TRH uses only the strictly needed miners fee, and the amount depends on the size of the file. TRH allow to calculate the amount needed before to properly upload the file.

To retrieve a stored file from the blockchain you need to know the address of the transactions and the password to decrypt the content, so what is needed is one of

passphrase (optionally a password)
key + password
address + password

From the version 0.1.0 TRH has an internal cache that reduce the amount of times a transactions has to be requested. Data in cache are the same available publicly on the blockchain, nothing is stored unencrypted and there’s no way to save passwords or keys.

Future plan

TRH is a CLI application but I perfectly know that the command line is a thing that scares the most of people so I will develop a way to make TRH accessible via a graphic interface. I don’t want to make TRH to become a website. TRH will remain a program that everyone can download and run. The only central point will remain the blockchain, nothing else.

The code

The code is not availabe poen source right now because I’m in active development with tests with private keys but my plan is to release it open source when it will have reached an acceptable level of maturity. There’s nothing hidden, TRH needs an Internet connection to connect to TAAL API to send transactions and to WhatsOnChain API to retrieve UTXO and transactions. No other connections are done, there’s no tracking of anything.
