Chainiac is an update framework that provides decentralized enforcement of development and release processes, independent verification of source-to-binary correspondence, transparency via a collectively-signed update timeline, and efficient release validation by arbitrarily out-of-date clients. This repository contains the bare-bone source code of the system and the code necessary to reproduce the experiments in the corresponding paper.

We use Python to extract metadata of Debian packages and snapshots of the Debian repository. You need to install
- Python 3.5 or later

Retrieving test data
Go to repositories/ and run
./get_files.sh to retrieve the list of the most downloaded Debian packages
http://popcon.debian.org/. Then run
to retrieve the snapshots of the Debian testing repository used in the experiments. This might take a while.
Go to simulation/ and execute
go build .
This will build a simulation binary. You can reproduce the experiments from the paper by running the binary with a toml configuraiton file as an argument.
