Wikipedia on Swarm Search Mechanism




over 1 year ago



10000 USD



  • E.T. wants to access Wikipedia, but the site is no longer accessible on the web.
  • They want to find a way to download the entire Wikipedia and access it offline, but this download requires a lot of traffic (500 GB of wiki mirror) and is difficult to update - there surely must be an easier, faster and more efficient way to access Wikipedia.
  • Fortunately, the Swarm network hosts a mirror of Wikipedia, so anyone connected to it can access and search through the complete set of information.
  • Wikipedia on Swarm is updated periodically (at minimum on a monthly basis) and is always accessible through the same link and the same means.


  • This is “Wikipedia on Swarm” prize’s winner project. This bounty is to implement a search engine over the winning project’s dataset.
  • The search engine will have to be used to retrieve the desired page.
  • The search engine will have to offer “suggested words” when the user starts typing.
  • Create a reusable solution that provides broader utility - components can be reused to search through large collections of small files like other ZIM archives (e.g. Project Gutenberg) or OpenStreetMap data.
  • Create or modify a web interface and/or an app to allow searching and reading of Swarm hosted content.
  • Clear deployment instructions - Anyone without a devops background should be able to run the solution.

Note: Hosting of a database of this scale on Swarm has not been efficiently automated yet. As of today, the Bee client can reliably upload and retrieve small files. For larger datasets, an efficient mechanism for upload should be implemented.

Technical requirements:

  • It will have to be native compatible with the dataset of “Wikipedia on Swarm” prize’s winner project.
  • The judging panel will attempt to search for several random pages to ensure that English Wikipedia has been uploaded to Swarm mainnet as required for this bounty.

Assessment Criteria


  • What is the final product’s user experience?
  • Does it offer suggested words?
  • How does it perform? We’d love the bounty to invite any innovation.
  • How much time/resources does it consume?


  • Meeting the listed requirements.
  • Quality of implementation: code, documentation, technical excellence.
  • Quality of user experience (with regards to uploading and, more importantly, with regards to using the uploaded wikipedia).
  • How innovative is your solution?
  • Technical complexity and optimisations.

Code of Conduct

Let’s build exciting things.

Projects need to support privacy, data interoperability and data sovereignty where applicable. For more details, get familiar with Fair data society's principles. Prize challenge:

  • Open source code licence:
  • any licence for the project shall include terms substantially similar to those of version 1.9 of the Open Source Definition, promulgated by the Open Source Initiative at
  • Documentation: how to run, how it works
  • Recorded video demonstration of the working solution
  • A working link to a public Github or Gitlab repository containing: the code, presentations, demo, documentation, and licence information
  • The submitted solution must be a working product ready to be deployed in production already integrated with Wikipedia on Swarm Prize’s winner.
  • The solution uses Swarm network as the underlying storage

The judging panel will attempt to retrieve several random pages to ensure that English Wikipedia has been uploaded to Swarm mainnet as required for this bounty.
