Devnet Quickstart
This page describes a quickstart method for running pd
+tendermint
to test
changes during development.
To start, you’ll need to install Tendermint v0.34
.
Generating configs
To generate a clean set of configs, run
cargo run --release --bin pd -- testnet generate
This will write configs to ~/.penumbra/testnet_data/
.
Running pd
You’ll probably want to set RUST_LOG
. Here’s one suggestion:
export RUST_LOG="warn,pd=debug,penumbra=debug,jmt=info"
To run pd
, run
cargo run --release --bin pd -- start --home ~/.penumbra/testnet_data/node0/pd
This will start but won’t do anything yet, because Tendermint isn’t running.
Running tendermint
To run Tendermint, run
tendermint --home ~/.penumbra/testnet_data/node0/tendermint/ start
in another terminal window.
Running pcli
To interact with the chain, first do
cargo run --release --bin pcli -- view reset
and then pass the -n
flag to any commands you run to point pcli
at your local node, e.g.,
cargo run --bin pcli -- -n 127.0.0.1 view balance
By default, pd testnet generate
uses the latest snapshot of the Discord’s
faucet channel, so if you posted your address there more than a week or two ago,
you should already have an allocation in your local devnet.
If not, reset the state as below, and edit the genesis.json
to add your address.
Resetting and restarting
After making changes, you may want to reset and restart the devnet:
cargo run --release --bin pd -- testnet unsafe-reset-all
You’ll probably also want to reset your wallet state:
cargo run --release --bin pcli -- view reset
At this point you’re ready to generate new configs, and restart both pd
and
tendermint
. The order they’re started in doesn’t particularly matter for
correctness, because tendermint
will retry connecting to the ABCI server until
it succeeds.
Optional: running smoke-tests
Once you have a working devnet running, you should be able to run the smoke tests successfully. This can be useful if you are looking to contribute to Penumbra, or if you need to check that your setup is correct.
To run the smoke tests:
- Make sure you have a devnet running (see previous steps)
- Run integration tests:
PENUMBRA_NODE_HOSTNAME=127.0.0.1 PCLI_UNLEASH_DANGER=yes cargo test --package pcli -- --ignored --test-threads 1
