Getting Started

Tangle is restaking network focused around complex offchain computations, such as MPC (multi party computation), zero-knowledge proof generation, AI services, and more.

If you would like to familiarize yourself with Tangle Network check out following repo and docs:

• Tangle Gadgets
• Tangle Docs
• Tangle Website

Prerequisites

This guide uses https://rustup.rs installer and the rustup tool to manage the Rust toolchain.

First install and configure rustup:

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

Great! Now your Rust environment is ready!

Note: You may need additional dependencies, checkout substrate.io for more information.

Installation using Nix

If you want to use Nix for development, please follow following instructions

1. Install Nix
2. Enable Flakes (if you are not already see here: Flakes)
3. If you have direnv installed, everything should work out of the box.
4. Alternatively, you can run nix flake develop in the root of this repo to get a shell with all the dependencies installed.

Run Tangle Testnet

1. Build tangle node.

  cargo build --release --features testnet

2. Execute tangle network setup script to run it locally.

./scripts/run-standalone-local.sh --clean

This should start the local testnet, you can view the logs in /tmp directory for all the authorities and use polkadotJS to view the running testnet.

3. To Start validating on the live testnet please visit Starting a validator on Tangle docs.

Troubleshooting

The linking phase may fail due to not finding libgmp (i.e., "could not find library -lgmp") when building on apple silicon. To fix this problem, run:

brew install gmp
# make sure to run the commands below each time when starting a new env, or, append them to .zshrc
export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/lib
export INCLUDE_PATH=$INCLUDE_PATH:/opt/homebrew/include
