Parity proof-of-stake test setup
This is an integration test of AuRa PoS with three Parity nodes running locally.
Usage
To configure the repository and run tests, execute npm run all.
Requirements
The aura-pos branch should be checked out in ../parity-ethereum and built in
debug mode.
Development
Adding new validator nodes and their keys
To add a new validator node, Parity should generate an account together with its secret key like so:
parity account new --config config/nodeX.toml --keys-path parity-data/nodeX/keys
given a node configuration file config/nodeX.toml and a newly created
directory parity-data/nodeX/keys. config/nodeX.toml should then be amended
with the validator address output by the above command. Also, the keys directory
parity-data/nodeX/keys should be committed to the Git repository: it is a part
of persistent Parity state which should be kept across state resets which happen
when you run npm run all.
With this done, the node can be added to the list of started nodes in
scripts/start-test-setup and to the list of stopped nodes in
scripts/stop-test-setup.
If the new node has to be an initial validator, the network spec should reflect
that: add the node's address to INITIAL_VALIDATORS in scripts/network-spec.
Simulation
We've created a NetLogo model for simulating the staking and rewards computation on networks of various sizes and having different input parameters.
