OsmosisAtomkraft

This repository is a workspace for Informal Systems' Atomkraft adaptations and TLA specs created specially for Osmosis audit project. All the important information regarding the audit can be found in Informal Systems & Osmosis partnership repository, where Osmosis Atomkraft is placed as a submodule under the 2022/Q4 folder

To clone just the Atomkraft artifacts Informal created during the audit

git clone [email protected]:informalsystems/OsmosisAtomkraft.git

To clone all the Atomkraft artifacts, including Osmosis source code at the relevant commit that has been audited:

git clone --recurse-submodules [email protected]:informalsystems/OsmosisAtomkraft.git

To update the submodules (Osmosis source code) if you've already cloned the repository

git submodule update --init --recursive

Setup

building osmosis

Current version of the Atomkraft tool is using Osmosis v13.1.0 to execute traces against. To setup the environment, you must build the osmosis locally with:

git submodule update --init
cd osmosis
make build

Building different version of Atomkraft:

To run traces against a different Osmosis version, run commands:

git submodule update --init
cd osmosis
git checkout $AUDIT_COMMIT
make build

Install Atomkraft

Installing Atomkraft is as easy as:

pip install atomkraft

However since Atomkraft is depending on:

• python 3.8 or newer
• python package manager - pip

it could be neccessary to follow the installation instructions from: Installing Atomkraft.

For basic usage of Osmosis Atomkraft tool - to run already generated test cases and scenarios, this is all you need.

If there is a need for "advance usage" - generating more traces and test cases that will be executed against the chaina, due to further TLA spec changes and/or newly defined scenario invariants, you should also check the Java dependency chapter from Informal's Atomkraft Installation.md

Working with Atomkraft and traces generated by Apalache

Generate traces

atomkraft model simulate --model-path=models/test_mp_gamm.tla --max-trace=3 --length=4 --traces-dir=traces/mp_gamm

Execute tests

atomkraft test trace --path=traces/mp_gamm --reactor=reactors/mp_gamm.py --keypath=action.tag

Execute scenarios created during the GAMM audit

The list of all the scenarios created and executed during the GAMM audit and the results can be found in scenarios/readme.md.

One example of executing scenatio trace is presented here:

atomkraft test trace --path=traces/scenarios/scenario8.itf.json --reactor=reactors/mp_gamm.py --keypath=action.tag
