This repository contains the implementation of the Decentralized Internet Archive realized in the context of a Master Thesis at the DEDIS laboratory at EPFL.

This repository is based on the DEDIS cothority template. It is highly experimental and still a prototype and should not be considered secure or reliable for real-world purposes.

This project is related to an EPFL Master Thesis report which can be used as a documentation. Plancherel Nicolas, Decentralized Internet Archive, EPFL 2018. You can found it in the doc/ folder.

More documentation and examples can be found at:

• To run and use a conode, have a look at Cothority Node with examples of protocols, services and apps

• Install a working go environment
• go get -u https://github.com/dedis/student_17_decenar
• Install the dependencies (please note that the following list may be incomplete and/or redundant):
  • "gopkg.in/dedis/onet.v1"
  • "gopkg.in/dedis/onet.v1/log"
  • "gopkg.in/dedis/cothority.v1/cosi/service"
  • "gopkg.in/dedis/onet.v1/crypto"

  • "bytes"
  • "errors"
  • "io/ioutil"
  • "regexp"
  • "sort"
  • "strings"

To test the archive installation, you can do the following:

• cd student_17_decenar/ (go to the repository folder)
• go install ./conode (install the conode module)
• go install ./decenarch (install the decenarch module)
• create a cothority with the number of nodes you want (see the cothority repository)
• conode server -c /path/to/conode/private.toml for each conode (run the local conode)
• decenarch k /path/to/general/public.toml (start the skipchain routine)
• decenarch s -u "https://url.of.your.choice" /path/to/general/public.toml (save a web page)
• decenarch r -u "https://url.of.your.choice" /path/to/general/public.toml (retrieve the saved web page
• The last line in the terminal should indicate where the webpage was stored on your filesystem
