Marscoin Core Desktop Wallet

Which Desktop Client Should I Run?

If you are a novice or beginner user looking for a desktop app, we recommend the Electrum-MARS wallet. It is lightweight, does not require downloading the full blockchain, and is easier to set up. Marscoin Core (below) is the reference implementation intended for developers, node operators, and advanced users who want full blockchain validation.

Overview

Marscoin Core is the reference implementation of the Marscoin protocol — the original, authoritative software from which all other Marscoin wallets and tools derive their understanding of the network rules. When you run Marscoin Core, you are running a full node that independently validates every transaction and every block on the Marscoin blockchain.

The Qt GUI provides a user-friendly desktop interface for sending and receiving MARS, while the underlying node software performs the critical work of network validation. Marscoin Core is the gold standard for users who want maximum trustlessness and want to contribute to the health of the network.

Key Features

Full Node Validation

Unlike lightweight wallets that rely on external servers for blockchain data, Marscoin Core downloads and validates the entire blockchain from the genesis block to the present. Every transaction, every block, every consensus rule is independently verified by your node. You trust no one — you verify everything yourself.

The full blockchain is approximately 2 GB in size and takes a few hours to sync on a broadband connection.

Qt GUI Interface

The graphical interface provides:

Wallet management — send and receive MARS with a familiar desktop interface
Transaction history — browse your complete transaction record
Coin control — choose which specific unspent outputs to include in a transaction (advanced feature for privacy and fee management)
Network status — monitor your node’s connection to the network, block height, and sync progress
Peer list — see which nodes you are connected to

Developer Console

Built into the GUI is a console that provides direct access to the Marscoin RPC (Remote Procedure Call) interface. Developers can issue any RPC command to query the blockchain, inspect transactions, manage the wallet programmatically, and interact with the node at a low level.

This makes Marscoin Core the essential tool for developers building on the Marscoin blockchain.

Network Contribution

Every running full node strengthens the Marscoin network. Your node:

Relays transactions to other nodes, helping transactions propagate quickly across the network
Serves block data to other nodes (including lightweight wallets) that request it
Enforces consensus rules — rejecting invalid transactions and blocks, protecting the network from attacks
Increases decentralization — the more independent nodes, the harder it is for any single party to disrupt the network

System Requirements

Storage: ~2 GB for the full blockchain (growing slowly over time)
RAM: 2 GB minimum, 4 GB recommended
Network: Broadband connection for initial sync and ongoing operation
OS: Windows 7+, macOS 10.14+, or Linux (Ubuntu 18.04+ or equivalent)

Marscoin Core runs comfortably on any modern desktop or laptop. It can also run on low-power devices like a Raspberry Pi for dedicated node operation.

Download and Setup

Download the latest release from GitHub
Install and launch the application
The node will begin syncing the blockchain — this takes a few hours on first run
Once synced, your wallet is ready to use
Encrypt your wallet using Settings > Encrypt Wallet — this protects your keys with a passphrase
Back up your wallet using File > Backup Wallet — store the backup file securely

Who Should Use Marscoin Core

Marscoin Core is recommended for:

Developers building applications on the Marscoin blockchain
Node operators who want to contribute to network decentralization
Advanced users who want full control and trustless validation
Miners who need a local node for solo mining or pool verification

For everyday use without running a full node, consider the Electrum wallet (lightweight desktop) or the Web Wallet (no installation required).
