Local relay chain setup
git clone https://github.com/paritytech/polkadot.git
Then, download the raw
raw-local-chainspec.json chain-spec file here and put it in the root of the cloned polkadot repository.At the time of writing this, the Pendulum parachain is using Polkadot dependencies of version
v0.9.29. So for compatibility purposes, you need to check out the respective branch before building the node.# Checkout correct branch
git checkout release-v0.9.29
# Build polkadot node
cargo build --release
From inside the cloned
polkadot repository (after building the node):Run relay-chain validator 1
./target/release/polkadot \
--alice \
--validator \
--base-path /tmp/relay/alice \
--chain ./raw-local-chainspec.json \
--port 30333 \
--ws-port 9944
If you ran this validator before and you would like to start afresh from genesis, then you would need to remove the folder
/tmp/relay first (and similarly for the following validator and collator nodes in this tutorial).Check the logs for the node identity of Alice (see line 4) and copy it to your clipboard
