Testing with Tangle

How to test your blueprint with Tangle

This guide will walk you through the process of setting and running Tangle node locally to test your blueprint with Tangle.

Prerequisites

First install and configure rustup:

# Install
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Configure
source ~/.cargo/env

Clone the tangle node

git clone https://github.com/tangle-network/tangle
cd tangle

Build the node for instant-seal

This is different from the production tangle runtime which produces a block every 6 seconds. The instant-seal node produces a block only when a transaction is available. This allows for faster testing cycles.

cargo build --release --features manual-seal,txpool,testnet

Run the node

./target/release/tangle --tmp --dev --validator -linfo \
--alice --rpc-cors all --rpc-methods=unsafe --rpc-external \
--rpc-port 9944 -levm=debug -lgadget=trace --sealing instant

If successful, you should see output indicating that the node is running:

./target/release/tangle --tmp --dev --validator -linfo --alice --rpc-cors all --rpc-methods=unsafe --rpc-external --rpc-port 9944 -levm=debug -lgadget=trace --sealing instant

How to build testnet runtime (without instant-seal)

To build tangle node, without instant-seal, you can run:

cargo build --release --features txpool,testnet

And use the following command to run the node:

./target/release/tangle --tmp --dev --validator -linfo \
--alice --rpc-cors all --rpc-methods=unsafe --rpc-external \
--rpc-port 9944 -levm=debug -lgadget=trace
