intOS-dfs

The decentralised file system (dfs) is a file system built for the internetOS (intOS). This works as a thin layer over Swarm (https://ethswarm.org/).

dfs can be used as follows

1. As a standalone, decentralised, personal data drive over the internet.
2. In conjunction with intOS-compute layer to work as a data provider for large scale parallel data processing engine over the internet.

User

The first step in dfs is to create a user. Every user is associated with a 12 word mnemonic based hd wallet. This wallet is passwod protected and stored in the datadir. whenever a user created a pod for himself, a new key pair is created using this mnemonic. A user can use this mnemonic and import their account in any device and instantly see all their pods.

What is a pod?

A pod is a personal drive created by a user in intOS-dfs. It is used to store files and related metadata in a decentralised fashion. A pod is always under the control of the user who created it. A user can create store any number of files or directories in a pod. The user can share files in his pod with any other user just like in other centralised drives like dropbox. Not only users, a pod can be used by decentralised applications (DApp's) to store data related to that user.

The basic storage unit in dfs is a pod. A user can create multiple pods and use it to organise their data. for ex: Personal-Pod, Applications-Pod etc.

How to run dfs?

• git clone https://github.com/jmozah/intOS-dfs.git
• cd intOS-dfs
• make binary
• yarn
• yarn build
• ./dist/dfs start (starts server and serves the front end too)

How to build dfs?

• yarn build (will build the frontend and copy it over to the go project)
• make binary
