Full Description


MetaDisk is a filehost web app, that allows anyone to upload files via a web
interface or API. Files are hashed and uploaded to public file hosting. Using
the hashes a node can look up the information of where that file was stored
using the Datacoin blockchain. This makes a file
uploaded to MetaDisk accessible through any node in the network.



This project depends on several other projects:

  • accounts (Optional) - Library for managing bandwidth on shared MetaDisk nodes. Allows users to buy, earn, or receive their bandwidth.

  • cloud-manager contains most of the
    file handling logic. It keeps track of all the uploaded files, keeps track of
    the files present in local cache, and handles database serialization.

  • file-encryptor is an encryption
    package that implements convergent encryption using HMAC-SHA256 and AES128-CTR.

  • metachains-dtc is a wrapper for
    the Datacoin client, using JSON RPC. It also contains a synchronization class,
    which allows one to synchronize data from and to the blockchain.

  • plowshare-wrapper provides a
    python interface to upload and download files from popular file hosting
    sites. It is a python wrapper of the plowshare tool.

  • web-core is the backend server that powers
    MetaDisk. It provides a JSON API web service, and the daemons to synchronize
    files to the cloud hosting services and to the blockchain.

MetaDisk, this project, provides a web interface to web-core, allowing you to
upload files and check the server status regarding bandwidth, disk usage, and
synchronization state.


Check for installation instructions. We use lunchbox for automated deployment.
