Context

4

  • Cothority framework
  • Protocols between conodes
  • Services (CoSi, Status…)
  • Apps (Cisc, PoP)

SLIDE 5

Collective Identity SkipChain (CISC)

  • Data storage
  • Key/value pairs
  • SSH public keys
  • Webpages
  • Provisioned skipchain
  • Only registered devices can

modify data

  • New data need to be accepted

by a threshold of devices

SLIDE 6

Proof-of-Personhood (PoP)

  • Anonymous authentication method
  • People get tokens
  • Use it to authenticate without giving

away your identity:

  • We only know that the user is part of a

group of person, but not his identity

Problem Statement

  • Current solution
  • User have to use a Command Line

Interface (CLI) to access these services

  • Cumbersome
  • Not adapted to the non technical user
  • Our project
  • Replace the CLI by a Cross-Platform

Mobile Application (CPMAC)
