Frequently Asked Questions

General Questions

What is Marscoin?

Marscoin is a peer-to-peer cryptocurrency designed from first principles for the unique constraints of a permanent human settlement on Mars. Launched in January 2014, it is one of the longest-running cryptocurrency projects in existence, with over twelve years of continuous blockchain operation and active development.

Marscoin is not merely a speculative token. It is a complete financial and governance infrastructure stack: a blockchain for transactions, a difficulty algorithm tuned for stable block production, a citizen registry for identity, a voting system for democratic governance, and integration with IPFS for immutable record-keeping. It is built to function as the economic foundation of an interplanetary civilization.

How many Marscoins are there?

The total supply of Marscoin is capped at approximately 39.57 million MARS (39,569,900 to be precise). As of 2025, essentially all Marscoin have been mined. The block reward has been halved multiple times according to the emission schedule established at launch, and the final coins have been issued.

This fixed supply is a deliberate design choice. Like Bitcoin’s 21 million cap, Marscoin’s supply limit ensures a predictable monetary policy that cannot be inflated by any authority. On Mars, where economic planning will be critical for a small settlement, a known and fixed money supply provides a stable foundation.

You can view the current distribution of Marscoin addresses via the blockchain explorer.

Where can I find the Marscoin Whitepaper?

The Marscoin whitepaper, titled “Trustless-Ledger Technology Implications for a Martian Society,” is available in the Academy and as a PDF download. It was authored by Lennart Lopin, James Burk, and Philipp Puaschunder, and originally presented at the Mars Society International Convention in 2014.

The whitepaper covers the light-speed penalty that makes an independent Mars currency necessary, the technical design decisions behind Marscoin, and the blockchain-based governance framework called the Martian Republic.

Is Marscoin a real, functioning cryptocurrency?

Yes. Marscoin has a live blockchain that has been running continuously since January 1, 2014. You can mine it, trade it on exchanges, send it between wallets, and use it for governance participation through the Martian Republic application. It is not a testnet, not a concept, and not vaporware. The blockchain has processed millions of transactions over more than twelve years of uninterrupted operation.

How Marscoin Works

How does Marscoin work?

Marscoin works like Bitcoin and Litecoin at its core. It is a decentralized network of nodes that maintain a shared ledger (blockchain) of all transactions. Miners compete to solve cryptographic puzzles (Proof of Work) to add new blocks of transactions to the chain. The network reaches consensus on the state of the ledger without any central authority.

To use Marscoin, you download a wallet application, which generates a pair of cryptographic keys: a public key (your address, which you share) and a private key (your secret, which you protect). You can then send and receive MARS, participate in governance, and interact with the broader ecosystem.

What makes Marscoin different from other cryptocurrencies?

Several properties distinguish Marscoin from the thousands of other cryptocurrency projects:

1. Purpose-built for Mars. Every design decision — from the 123-second block time to the Scrypt algorithm to the rejection of SegWit — is made with Mars settlement constraints in mind. This is not a generic altcoin with a Mars theme; it is an engineering project optimized for interplanetary operation.

2. The Martian Republic. Beyond currency, Marscoin includes a full governance platform: citizen registry, congressional voting with secret ballots, research logbook, inventory tracking, and planetary registry. No other cryptocurrency offers this level of integrated governance infrastructure.

3. Twelve-year track record. Launched in January 2014, Marscoin has been operating continuously for over twelve years. In a space notorious for abandoned projects and exit scams, this longevity demonstrates genuine commitment.

4. Fixed supply, completed mining. With all ~39.57 million MARS mined, the monetary policy is fully known and immutable. There are no future inflation surprises.

5. Anti-complexity philosophy. Marscoin deliberately rejects features like SegWit and RBF that add complexity without serving Mars-specific needs. Simplicity is a survival trait for software that must operate 225 million kilometers from the nearest developer.

Why not just use Bitcoin on Mars?

Bitcoin is not suitable for Mars for several fundamental reasons:

• 10-minute block times are too slow for everyday transactions in a small settlement.
• Enormous energy consumption. Bitcoin’s security model depends on massive hash power, requiring gigawatts of electricity. Mars cannot spare the energy.
• Earth-dominated mining. A Mars Bitcoin node would always be 4-24 minutes behind Earth’s chain tip due to the speed of light, making it perpetually vulnerable to reorganization by Earth miners.
• Cultural sovereignty. A Mars settlement needs a financial system that is theirs — not an extension of Earth’s economy subject to Earth’s consensus changes.

Marscoin addresses all of these constraints with 2-minute blocks, energy-efficient Scrypt mining, and an independent network designed for eventual autonomous operation on Mars.

Mars Settlement

When will Marscoin actually be used on Mars?

The honest answer: when humans establish a permanent settlement on Mars. Marscoin is building the infrastructure now so that it is ready, tested, and battle-proven when that day comes.

The current timeline for Mars settlement depends primarily on SpaceX’s Starship program, NASA’s Artemis program, and other commercial and government initiatives. Optimistic projections place the first crewed Mars landing in the early-to-mid 2030s, with permanent settlement following within a decade.

In the meantime, Marscoin functions as a fully operational cryptocurrency on Earth. The blockchain runs, transactions process, governance votes occur, and the community grows. This is not waiting — it is rehearsing.

How can a cryptocurrency work on Mars with the communication delay?

The communication delay between Earth and Mars (4-24 minutes one way) is precisely why Mars needs its own independent cryptocurrency rather than relying on Earth-based financial systems.

On Mars, the Marscoin network would operate as an independent blockchain. Mars nodes would mine blocks, process transactions, and maintain consensus among themselves without real-time communication with Earth. The settlement’s computers would run full nodes and mine using the settlement’s own power generation.

Periodic synchronization with the Earth chain could occur during communication windows, but the Mars chain would be self-sufficient. The Marscoin protocol is designed to handle exactly this scenario — small number of nodes, variable hash power, and intermittent external connectivity.

Is it really possible to build a base on Mars?

Yes. It is more technologically feasible today to send humans to Mars than it was to send them to the Moon in 1961. The engineering challenges are significant but well-understood: reliable heavy-lift launch vehicles (SpaceX Starship), in-situ resource utilization (producing fuel and oxygen from the Martian atmosphere), closed-loop life support, radiation shielding, and sustainable food production.

Dr. Robert Zubrin’s Mars Direct plan, published in 1990 and detailed in his book The Case for Mars, demonstrated that a crewed Mars mission was achievable with 1990s technology and a modest budget. Since then, technology has advanced dramatically — reusable rockets, 3D printing, improved solar and nuclear power, and advances in life support systems.

For an excellent introduction, see Dr. Zubrin’s The Case for Mars or the Mars Society website.

Can an economy exist with so few people on a planet?

Yes. Even a small group of people will quickly need mechanisms for resource allocation and value exchange beyond simple barter.

In the earliest phase, a Mars settlement might operate on a mix of sharing and barter. But as the community grows and specialization develops — one person focuses on water extraction, another on food production, another on equipment maintenance — the inefficiencies of barter become acute. A medium of exchange becomes necessary.

Cryptocurrency is ideal for this because it requires no external infrastructure — no banks, no payment processors, no government backing. A single node running on a settlement computer creates a functional financial system. As the population grows from dozens to hundreds to thousands, the same system scales seamlessly.

What happens when Marscoin leaves Earth?

All existing addresses and balances will continue to be valid on Mars. The blockchain history — every transaction, every governance vote, every logbook entry — accompanies the protocol to Mars.

The transition could involve a snapshot fork at a predetermined block height, after which the Earth chain and Mars chain evolve independently. Earth holders retain their Earth-chain MARS; the Mars chain continues with the same history but begins producing blocks independently on Mars.

For holders who prefer to liquidate before the fork, Marscoin can be traded on exchanges at any time.

How will future Mars inhabitants use the currency?

The same way we use cryptocurrency today, but for everything: buying supplies at the settlement store, paying for equipment repairs, compensating specialists for their work, contributing to community projects, and participating in governance.

The Martian Republic application provides a single interface for all of this — wallet, citizen ID, voting, logbook, and more. A settler opens the app, scans a QR code, and payment is complete in approximately two minutes (one block confirmation).

Community and Organization

Is Marscoin affiliated with The Mars Society?

Marscoin and The Mars Society have a collaborative but independent relationship. Several Marscoin contributors are Mars Society members, and the projects share a common mission of advancing Mars settlement. The Marscoin Foundation donated 500,000 MARS to The Mars Society in 2014, and an additional 500,000 MARS originally donated to Mars One was later transferred to The Mars Society when Mars One ceased operations.

James Burk, Executive Director of The Mars Society, has been a collaborator on the Marscoin project since its early days and is a co-author of the whitepaper.

However, there is no formal organizational merger or affiliation. Marscoin is an independent open-source project. The Mars Society is an independent nonprofit advocacy organization. They are aligned in mission but separate in governance.

For the full history, see Marscoin and The Mars Society.

What is the Marscoin Foundation?

The Marscoin Foundation LLC is the entity that stewards the Marscoin project. It maintains the open-source codebase, coordinates protocol upgrades, manages the trademark (USPTO registered), and supports ecosystem development. The Foundation does not control the network — Marscoin is a decentralized protocol — but it provides organizational continuity and legal representation.

How can I contribute to Marscoin?

There are many ways to get involved:

• Run a full node. This strengthens the network by adding decentralization.
• Mine Marscoin. Either independently or through merged mining with Litecoin via Longpool.
• Develop software. The codebase is open source on GitHub.
• Participate in governance. Download the Martian Republic app and register as a citizen.
• Create content. Write articles, produce videos, build educational materials.
• Spread the word. Tell people about Marscoin. The most valuable thing any project can have is attention from the right people.
• Donate. Support The Mars Society and other organizations working toward Mars settlement.

Mining

How do I mine Marscoin?

Marscoin uses the Scrypt Proof of Work algorithm. You can mine it using:

• Scrypt ASIC miners pointed at a mining pool (most efficient)
• GPU mining with Scrypt-compatible software (less efficient but accessible)
• Merged mining with Litecoin through pools like Longpool (recommended — mine Litecoin and Marscoin simultaneously)

For detailed instructions, see the Mining Guide.

What is merged mining and why does it matter?

Merged mining (AuxPoW) allows miners to submit the same proof of work to multiple blockchains simultaneously. Since February 2025, Marscoin can be mined alongside Litecoin at no additional energy cost. This provides Marscoin with approximately 2 TH/s of network hash rate — security far beyond what its independent economy could sustain.

For the full technical explanation, see Merged Mining & AuxPoW.

Looking Forward

Even if Mars settlement happens, how do you know Marscoin will be the currency?

No one can guarantee the future. But Marscoin has several powerful advantages:

1. First mover. Marscoin has been purpose-built for Mars since 2014. No other project has this depth of development or focus.
2. Network effects. If enough early Mars supporters hold and use Marscoin, the natural economic incentive is to continue using the currency that already has distribution and infrastructure.
3. Technical suitability. The protocol is specifically engineered for Mars constraints — block time, energy efficiency, governance integration. A generic cryptocurrency would need extensive modification to serve the same purposes.
4. Community alignment. The Marscoin community is composed of people who care about Mars settlement, not just financial returns. This alignment of mission and incentives is rare and valuable.

As the project FAQ has stated since the early days: if enough people adopt Marscoin — including the early settlers — there will be a natural tendency to install the very currency that the early adopters and space enthusiasts have already invested in. Network effects are powerful.

How can this work? It sounds too ambitious.

As the saying goes: “First they ignore you, then they laugh at you, then they fight you, then you win.” We know that Marscoin stretches people’s imagination, but it is a serious project. Consider: Lily Allen’s 100,000 Bitcoin invitation for a concert in 2009 would have paid for a Falcon Heavy rocket launch just four years later — and Bitcoin’s wealth is concentrated in a far smaller group of people than Marscoin’s distribution.

At a time when Bitcoin was still compared to “email in 1991” and SpaceX’s private Mars exploration efforts received harsh criticism, many dismissed the idea. But to the developers and space enthusiasts behind this project, Marscoin has always been a serious effort to boost space exploration through decentralized technology and community action.

The Marscoin launch in January 2014 was open to the public. Since then, thousands of miners have helped spread the network. The community donated 500,000 MARS each to The Mars Society and Mars One (with the Mars Society later taking ownership of all one million donated MARS when Mars One ceased operations). Marscoin’s distribution is spread more fairly and equally than Bitcoin or Litecoin’s wealth concentration.

Are you fans of Elon Musk?

Who is not? Elon Musk’s work with SpaceX has done more to advance the realistic prospect of Mars settlement than any other private effort in history. The Marscoin community is grateful for his contributions to getting humanity to Mars. SpaceX’s Starship program represents the most promising pathway to Mars, and Marscoin’s infrastructure is designed to be ready when that pathway delivers its first settlers.

Is it too late to get involved?

No. With a market cap well under $10 million and a fully operational blockchain, Marscoin is still in its early phase. The opportunity for early participants to contribute meaningfully to the ecosystem — and to be recognized as foundational contributors when Mars settlement arrives — remains wide open.

Open for Collaboration Proposals

We are inviting thinkers, innovators, and partners for collaborative projects and proposals.

In 2013, we had a vision: a future where Mars leveraged the transformative power of blockchains for finance, governance, and civic engagement. Our goal was to encapsulate this grand vision, ensuring that the pioneering spirit of such a future remained untainted by the risks of scams and fraud that often accompany emerging technologies. Throughout a decade-long journey, we have been fortunate to gather a community of volunteers, enthusiasts, scientists, researchers, and — quite possibly — the first Martians.

A milestone in our journey was the successful registration of the trademark “Marscoin” with the USPTO. This was more than a legal accomplishment; it was a declaration of our commitment to this vision and our community’s ideals. However, with this step comes a greater responsibility and a renewed invitation. We understand that the ambitious infrastructure required for Mars and blockchain integration cannot be built by us alone.

That is why we are extending an open call for collaboration. If you have an innovative idea, a project that aligns with our mission, or a proposal that could benefit from the Marscoin brand, we want to hear from you. We are looking for partners who share our excitement for developing the future infrastructure of blockchains and are eager to contribute to something truly groundbreaking.

Join us in this extraordinary endeavor. Your insights, creativity, and passion are what will propel us forward. Let us work together to turn this bold vision into reality. If you are inspired by the prospect of contributing to the Marscoin project, reach out on Discord or Telegram.
