FileTribe

FileTribe is a blockchain-based decentralized file-sharing and editing system built on Ethereum and IPFS.

Contract address of the development version on Ropsten: 0xa53336064E1c14a6a9c0a612Fe445d201a1982DE

Dependency

In order to use FileTribe, you will need a running IPFS daemon. To install IPFS, download it and then run

$ tar xvfz go-ipfs.tar.gz
$ cd go-ipfs
$ ./install.sh

For more information see here. You also need go-ethereum's abigen, which is bundled into the basic ethereum package.

$ apt-get install ethereum 

Alternately you can build it as well. For more information on that see here.

Building the sources

To successfully build the FileTribe client application, you need Go (v1.10 <=) and Truffle. To install Truffle, run $ npm install -g truffle. For more information on installing Truffle, see here. If both dependencies are installed, run

$ make all

This will download the Go dependencies, compile the solidity sources and create Go bindings to them. Note that you may have to use make in sudo mode since go-ethereum's abigen might fail when trying to resolve the dependencies of the generated Go files.

Getting started

An unsafe developer version of FileTribe is deployed on the Ropsten test network. The default config.json contains the necessary information to reach that application.

1. To use FileTribe you need to edit $HOME/.filetribe/config.json to include your mnemonic that generates your ethereum account. If you do not have any, you can generate one using an online mnemonic generator or by using MetaMask.

   "EthAccountMnemonic": "your own long nice menmonic...",
   

2. To perform contract method calls you will need some ether. Use a faucet, like the one hosted by MetaMask to acquire ether.

   1. Navigate to MetaMask's Test Ether Faucet.

   2. Connect to the Ropsten Test Network using MetaMask.

   3. The faucet will link to your first account. Click "Request 1 Ether From Faucet" to submit your request.

   4. Within a short period of time, your account will be populated with the requested ether.

Note, that FileTribe client uses Infura to use the blockchain application by default. If you want it to use your own specific Ethereum node or you deployed your own version of FileTribe and you want to use that contract, you can set these in the config.json file.

Start IPFS daemon

FileTribe uses IPFS as its data storage layer so the client needs an IPFS daemon which it can talk to. The clients communicate with each other through the IPFS daemon's built in libp2p service which has to be enabled explicitly.

$ ipfs init
$ ipfs daemon --enable-pubsub-experiment </dev/null &>/dev/null &
$ ipfs config --json Experimental.Libp2pStreamMounting true

Start the client application

You can configure the FileTribe daemon with $HOME/.filetribe/config.json. If you have a running Ethereum network, on which the FileTribe contracts were deployed and an IPFS daemon you can start the client:

$ filetribe daemon

Now that you have a running filetribe daemon you can start interacting with it. Since most of the operations you perform will result in a contract method call on the blockchain, these operations will not come into force in an instant.

You can check your pending transactions by executing filetribe ls -tx and lookup the results on Etherscan's Ropsten part.

1. Sign up

   Execute

   $filetribe signup <username>
   

   to sign up and wait for the blockchain transaction to complete. After successfully signe up, a filetribe/<usnername> directory should appear in your $HOME directory.

2. Create a group

   Execute

   $filetribe group create <groupname>
   

   to create a group. As usually, wait for the transaction to complete. After it is done, the directory $HOME/filetribe/<username>/<groupname> should appear. This will be the group's repository. You can share your files with your group by copying them into this folder.

3. Invite others

   You can invite other users by executing

   $ filetribe group invite <groupaddress> <other user's filetribe account address>
   

4. Commit changes

   Do not forget to commit your changes, as your file shares/modifications will be visible to your group mates only if you have committed them. Execute

   $ filetribe group repo commit <groupaddress>
