What it is

For dApp developers

If you create a dapp using Leap Network you can either use an existing public node or start your own leap-node instance.

Running your own node is encouraged as it increases decentralization — you can autonomously monitor the network is not compromised and your funds are safe.

If you don't want to run a full node or just curious, you don't need this repo — you can freely use our public node to connect to and jump straight to our document.

Documentation for dApp developers

For validators

You will definitely need to run a leap-node instance, if you want to become a validator on Leap Network. Validating Leap Network is a way to earn money by ensuring the network security and thus delivering a public good.

Read more on becoming a Validator

Getting Started

Please find all necessary instructions to set up your own node and on how to become a validator in our LeapDAO docs.

Quick start

# Install latest leap-node from NPM. You may need different version depending on the network you connect to.
npm install -g leap-node

# Start the node connecting to testnet. It will take a few hours to sync with the tip of the network.
DEBUG=tendermint,leap-node* leap-node --config=https://testnet-node.leapdao.org

Hardware Requirements

• 64 bit CPU

Prerequisites

• Node.js 8+ (10/12 compatible)
• build-essential

Install

Install latest leap-node from NPM. You may need different version depending on the network you connect to:

npm install -g leap-node

Run

To run the node you execute a leap-node with commandline arguments.

The bare minimum of arguments required are:

• --config to specify a path to local JSON file with network configuration or a JSON RPC url of another leap-node to get configuration from
• --rootNetwork to specify a root chain provider url (e.g. your own ethereum node or infura)

Chain ID of the root chain provider should match the rootNetworkId in the network configuration file (e.g. 4 for Rinkeby).

DEBUG=tendermint,leap-node* leap-node [ARGS] --config=<path-to-config.json> --rootNetwork=<root-network-provider-url>

Once started and synced with the network, the node exposes a Leap JSON RPC on a port 8645. You can use your node now or apply to become a validator.
