Run an alphanet node with Docker

Docker images are published for every tagged release. Learn more with moonbeam --help.

# Join the public testnet
docker run --network="host" purestake/moonbeam:v0.6.1 --chain alphanet

Run a local development node with Docker

Developers who are building dApps to run on moonbeam, may want a lightweight node to work with locally. You can quickly spin up a single node with no relay chain backing it using the development service.

# Run a dev service node.
docker run --network="host" purestake/moonbeam:v0.6.1 --dev

Sealing options

The command above will start the node in instant seal mode. It creates a block when a transaction arrives, similar to Ganache's auto-mine. You can also choose to author blocks at a regular interval, or control authoring manually through the RPC.

# Author a block every 6 seconds.
docker run --network="host" purestake/moonbeam:v0.6.1 --dev --sealing 3000

# Manually control the block authorship and finality
docker run --network="host" purestake/moonbeam:v0.6.1 --dev --sealing manual

Prefunded Development Addresses

Running Moonbeam in development mode will pre-fund several well-known addresses that (mostly) contain the letters "th" in their names to remind you that they are for ethereum-compatible usage. These addresses are derived from Substrate's canonical mnemonic: bottom drive obey lake curtain smoke basket hold race lonely fit walk

Build the Moonbeam Node

To build Moonbeam, you will need a proper Substrate development environment. If you've never worked with a Substrate-based blockchain before, you should probably try the [Setting Up a Moonbeam Node] (https://docs.moonbeam.network/getting-started/local-node/setting-up-a-node/) docs first. If you need a refresher setting up your Substrate environment, see [Substrate's Getting Started Guide] (https://substrate.dev/docs/en/knowledgebase/getting-started/).

# Fetch the code
git clone https://github.com/PureStake/moonbeam
cd moonbeam

# Build the node (The first build will be long (~30min))
cargo build --release

Run tests

Moonbeam has Rust unit tests as well as typescript integration tests. These tests are run in CI, and can also be run locally.

# Run the Rust unit tests
cargo test

# Install dependencies for integration tests
cd moonbeam-types-bundle
npm i

cd ../tests
npm i

# Run integration tests
npm test

Chain IDs

The Ethereum specification described a numeric Chain Id. The Moonbeam mainnet Chain Id will be 1284 because it takes 1284 milliseconds for a moonbeam to reach Earth.

Moonbeam nodes support multiple public chains and testnets, with the following Chain Ids.

Network Description	Chain ID
Local Parachain TestNet	1280
Local Development TestNet	1281
Reserved for other TestNets	1282 - 1283
Moonbeam (Polkadot)	1284
Moonriver (Kusama)	1285
Moonrock (Rococo)	1286
Moonbase Alpha TestNet	1287
Reserved for other public networks	1288 - 1289

Runtime Architecture

The Moonbeam Runtime is built using FRAME and consists of pallets from substrate, frontier, cumulus, and pallets/.

From substrate:

Utility: Allows users to use derivative accounts, and batch calls
Balances: Tracks GLMR token balances
Sudo: Allows a privileged account to make arbitrary runtime changes - will be removed before launch
Timestamp: On-Chain notion of time
Transaction Payment: Transaction payment (fee) management
Randomness Collective Flip: A (mock) onchain randomness beacon. Will be replaced by parachain randomness by mainnet.

From frontier:

EVM: Encapsulates execution logic for an Ethereum Virtual Machine
Ethereum: Ethereum-style data encoding and access for the EVM.

From cumulus:

ParachainUpgrade: A helper to perform runtime upgrades on parachains
ParachainInfo: A place to store parachain-relevant constants like parachain id

The following pallets are stored in pallets/. They are designed for Moonbeam's specific requirements:

Ethereum Chain Id: A place to store the chain id for each Moonbeam network
Author Inherent: Allows block authors to include their identity in a block via an inherent
Parachain Staking: Minimal staking pallet that selects collators by total amount at stake

Contribute

Moonbeam is open source under the terms of the GPL3. We welcome contributions. You can explore our crate-level documentation at https://purestake.github.io/moonbeam

Code style

Moonbeam is following the Substrate code style
We provide a .editorconfig (compatible with VSCode using RLS)
