Source

The Hedera Local Node project allows developers to set up their own local network. The local network is composed of one mirror node and one consensus node. You can set this up by either using the CLI tool or by running Docker.

Docker

Requirements

Node.js >= v14.x and <= v16.x
- Node version check: node -v
NPM >= v6.14.17 and <= v8.5.0
- NPM version check: npm -v
Docker >= v20.10.x
- Docker version check: docker -v
Docker Compose => v1.28.0 && <= 1.29.2
- Docker Compose version check: docker-compose -v

Note:

Ensure to use Docker Compose version 1.29.2 on macOS, due to known bug in Docker Compose V2.
Ensure the gRPC FUSE for file sharing and Use Docker Compose V2 settings are disabled in the docker settings.

Note: The image may look different if you are on a different version

Ensure the following configurations are set at minimum in Docker Settings -> Resources and are available for use
- CPUs: 6
- Memory: 5GB
- Swap: 1 GB
- Disk Image Size: 59.6 GB

Note: The image may look different if you are on a different version

Start Your Local Network

Clone the hedera-local-node repo

git clone https://github.com/hashgraph/hedera-local-node.git

CD to the hedera-local-node directory

    cd hedera-local-node

Run docker-compose up -d from the terminal to get the network up and running
Set-up your local network client by following this tutorial

Stop Your Local Network

Run docker-compose down -v; git clean -xfd; git reset --hard to stop and remove the containers, volumes and clean manuelly generated files. If you would like to keep any files created manuelly in the working directory please save them before executing this command.

Network Variables

These are the local network variables to interact with the consensus and mirror node.

Consensus Node Endpoint
- 127.0.0.1:50211
- The IP address and port of the local consensus node
Consensus Node Account ID
- 0.0.3
- The node account ID to submit transactions and queries to
Mirror Node GRPC Endpoint
- 127.0.0.1:5600
- The mirror node network to use
Mirror Node REST API Endpoint
- 127.0.0.1:5551
- The endpoint to submit rest API requests to
Account ID
- 0.0.2
- The account ID to use to pay for transactions and queries
Account Key
- 302e020100300506032b65700422042091132178e72057a1d7528025956fe39b0b847f200ab59b2fdd367017f3087137
- The private key to account 0.0.2 to sign transactions and queries with

Folder set up

compose-network folder has the static files needed for starting Local network.
network-logs folder will be created at runtime and will have all the log files generated after starting local node.

Steps to change the memory limits and properties

The following environment variables can be changed in the .env file for various memory limits

Platform
- PLATFORM_JAVA_HEAP_MIN
- PLATFORM_JAVA_HEAP_MAX
Consensus node
- NETWORK_NODE_MEM_LIMIT
Mirror node
- MIRROR_GRPC_MEM_LIMIT - memory limit for mirror node gRPC
- MIRROR_IMPORTER_MEM_LIMIT - memory limit for mirror node importer
- MIRROR_REST_MEM_LIMIT - memory limit for mirror node rest api
- MIRROR_WEB3_MEM_LIMIT - memory limit for mirror node web3
To change application.properties, api-permission.properties or bootstrap.properties properties, update the APPLICATION_CONFIG_PATH to the location of updated config folder in .env file

IMPORTANT : Ensure to do docker-compose down -v; git clean -xfd; git reset --hard and then docker-compose up -d for the new changes to take any effect.

✘ The keys under network-node (hedera.key, hedera.crt and the keys folder) are only intended to be used for testing with this docker based local network. These keys should not be used with any other networks.

CLI Tool

@hashgraph/hedera-local

What

This package defines a basic cli commands, that can be executed via node (npx), for interacting with the Local Hedera Network.

Exposed urls are:

Consensus Node Url - 127.0.0.1:50211
Node Id - 0.0.3
Mirror Node Url - http://127.0.0.1:5551

Installation

Official NPM Release

The command below can be used to install the official release from the NPM repository. This version may not reflect the most recent changes to the main branch of this repository.

This version uses a baked in version of the Docker Compose definitions and will not reflect any local changes made to the repository.

npm install @hashgraph/hedera-local -g

Using hedera-local

$ hedera

Local Hedera Package - Runs consensus and mirror nodes on localhost:
- consensus node url - 127.0.0.1:50211
- node id - 0.0.3
- mirror node url - http://127.0.0.1:5551

Available commands:
    start - Starts the local hedera network.
        options:
            --d or --detached for starting in detached mode.
            --h or --host to override the default host.
            --n or --network to override the default configuration. Defaults to mainnet.
    stop - Stops the local hedera network and delete all the existing data.
    restart - Restart the local hedera network.
    generate-accounts <n> - Generates N accounts, default 10.
        options:
            --h or --host to override the default host.

Note: Generated accounts are 3 types. All of them are usable via HederaSDK or @hashgraph/hethers. Only Alias ECDSA accounts can be imported into wallet like Metamask or used in ethers.

Commands

`hedera start <options>`

Demo

--accounts - Default is 10. Specify the number of accounts to generate at startup. The first 10 are with predefined private keys, and the next ones are with random generated private keys.
--h / --host - Override the default host.

`hedera restart <options>`

Demo

--accounts - Default is 10. Specify the number of accounts to generate at startup. The first 10 are with predefined private keys, and the next ones are with random generated private keys.
--h / --host - Override the default host.

`hedera start -d <options>`

--h / --host - Override the default host.

Network specific configuration

Network specific configurations can be applied using the -n/--network option when starting/restarting the local node. Pre-configured options are mainnet, previewnet, testnet and local

To create a custom network configuration, create a configs folder in the root of your project, then inside create <config_name>.json config file.

You can apply the configuration using the -n/--network options, e.g. hedera start --network <config_name>

You can use it in a hardhat project alongside with Hardhat Hethers Plugin by adding the following config:
