MASTNODE VS DIY: WHICH AIS SETUP IS RIGHT FOR YOU
A practical guide to joining the MastChain network — and what your hardware choice means for your rewards, your data quality, and the network you're building.
MastChain launched on the back of a simple idea: anyone with a radio receiver and an internet connection could contribute live vessel tracking data to a decentralised maritime network and earn MAST tokens in return. In the early days of the network, that meant building your own station from off-the-shelf parts — a Raspberry Pi, a software-defined radio dongle, a marine-band antenna. Thousands of contributors did exactly that, and the network grew to cover 60+ countries and 450,000 square kilometres of coastline as a result.
In June 2026, MastChain ships its first dedicated hardware: MastNode. Purpose-built for AIS data collection, designed in partnership with industrial hardware manufacturer MonsPro, and the first production device built specifically for a maritime DePIN network.
So which path should you take? The honest answer is: it depends on who you are, what you want to get out of it, and where you're deploying. This guide walks through both options in full.
WHAT BOTH SETUPS ARE ACTUALLY DOING
Before comparing hardware, it helps to understand what the task is. AIS — the Automatic Identification System — operates on two VHF frequencies: 161.975 MHz and 162.025 MHz. Large commercial vessels broadcast their position, speed, heading, and identity on these channels every few seconds. A receiver tuned to those frequencies captures those broadcasts, decodes them, and passes them upstream.
In a traditional setup, that upstream destination is a centralised aggregator — MarineTraffic, AISHub, VesselFinder. You donate your data and get a premium subscription in return, if you're lucky.
In MastChain, the upstream destination is a cryptographically verified, distributed data pipeline on the peaq blockchain. Your station holds a registered identity on the network. Every signal it receives is timestamped, geotagged, and cryptographically signed before it enters the pipeline. You earn MAST tokens based on the quality, reliability, and geographic value of your coverage. The data carries provenance — a traceable record of which physical device captured it, when, and where.
Both the DIY setup and MastNode do this. The question is how well, how reliably, and how much effort it takes to get there.
THE DIY SETUP: WHAT IT IS AND HOW TO BUILD ONE
The original MastChain station is a community creation. The most common build uses three components:
- A Raspberry Pi 3 or 4 (the compute and network backbone)
- An RTL-SDR dongle such as the RTL-SDR Blog V4 (the radio receiver)
- A VHF antenna tuned to ~162 MHz (the aerial)
Optionally, contributors add a Uputronics filtered preamp to improve weak signal reception, and a GPS module or NTP sync for precise timestamps — both of which improve data quality and therefore rewards.
Once the hardware is assembled, installation is handled by MastControl — a one-line script maintained by MastChain that deploys the MastRadar software (based on AIS-catcher), configures automatic uploads to the MastChain API, and handles station registration. The setup process looks like this:
1. Create an account at app.mastchain.io
2. Generate a station token
3. Run: curl -sSL https://raw.githubusercontent.com/mastchain/mastcontrol/refs/heads/main/mastcontrol.sh | sudo bash -s -- install
4. Paste your station token when prompted
5. Verify with: sudo mastcontrol status
From hardware assembly to first data submission, an experienced builder can have a station running in an afternoon. For someone encountering Linux for the first time, it may take longer — but the community documentation and Discord support are well developed, and the Hackster.io build guide by contributor Dan Jugy is one of the clearest hardware project walkthroughs in the DePIN space
WHAT A DIY SETUP COSTS
A functional DIY station can be put together for roughly:
- Raspberry Pi 4 (2GB): £35–45
- RTL-SDR Blog V4 dongle: £30–35
- Marine VHF antenna + cable: £25–60 depending on quality
- Uputronics filtered preamp (optional but recommended): £35
- Enclosure, power supply, miscellaneous: £15–25
Total: approximately £140–200 for a well-specified build, or as low as £90 if you already have some components. Many contributors repurpose older Raspberry Pi boards or use equipment they already owned for other SDR projects.
Running costs are minimal — a Pi 4 at idle draws around 3W, roughly £15–20 per year at average UK electricity prices.
DIY STRENGTHS
Accessibility: No waiting list, no shipping timeline. If you have the parts or can order them, you can be running within days. For contributors in countries where MastNode shipping logistics are complex, the DIY route may be the faster option regardless of preference.
Tinkerer appeal: The DIY setup is fully open. You can inspect the software stack, modify the configuration, experiment with different antenna setups, and learn a great deal about SDR, Linux, and AIS signal processing in the process. The RTL-SDR community has been building and sharing AIS receiver knowledge for years, and MastChain plugs directly into that ecosystem.
Flexibility: A Pi-based setup can be adapted for unusual deployment environments — off-grid solar/battery operation, remote mountings, integration with existing home automation or network infrastructure. The hardware is general-purpose by design.
Multiple use cases: Nothing stops a DIY station from simultaneously feeding MastChain and a personal MarineTraffic feeder, a local vessel traffic display, or other AIS projects. The RTL-SDR dongle doesn't care where the decoded data goes.
DIY LIMITATIONS
Performance ceiling: This is the most significant practical gap. In six months of joint field testing under identical antenna and installation conditions, MastNode outperformed equivalent DIY stations by up to 60% in unique vessels detected. The gap comes from hardware design — specifically the dual-channel simultaneous reception, the integrated GNSS with pulse-per-second timing, and the hardware-based secure element, none of which a standard RTL-SDR dongle provides.
Single-channel reception: A standard RTL-SDR dongle receives one AIS frequency at a time. AIS transmits on two channels. Software switches between them rapidly, but brief gaps in reception are possible, particularly during high-traffic periods. MastNode covers both channels simultaneously with no gaps.
Timestamp accuracy: AIS data quality is partly a function of how precisely each message is timestamped. A Raspberry Pi using NTP for time synchronisation is good. MastNode uses a GNSS module with pulse-per-second (PPS) output for sub-millisecond timing accuracy — a meaningful difference for the network's anomaly detection and cross-referencing capabilities.
Cryptographic identity: DIY stations rely on software-based station tokens for their network identity. MastNode uses an ATECC608 secure element — a hardware security chip physically embedded in the device — to generate and store its cryptographic identity. This is a higher standard of identity assurance, which matters for the network's data provenance guarantees and may affect how rewards are weighted as the network matures.
Reliability and uptime: A Raspberry Pi is a capable single-board computer but was not designed for continuous industrial operation. MastNode ships in an industrial-grade enclosure rated for -20°C to +65°C operating temperatures and is designed for the unattended, always-on deployment profile that maximises rewards. An exposed Pi in a loft or outdoor enclosure may be more susceptible to heat, humidity, or power issues.
Maintenance overhead: DIY stations require occasional attention — software updates, driver issues, occasional reboots. MastNode's firmware is managed over-the-air by MastChain.
MASTNODE: WHAT YOU'RE GETTING
MastNode is a purpose-built AIS collection station. The technical specification:
- Dual-channel AIS receiver: covers 161.975 MHz and 162.025 MHz simultaneously, with no gaps
- Integrated GNSS module with PPS: provides precise position and sub-millisecond timestamp accuracy for every data packet
- ATECC608 secure element: hardware-based cryptographic identity and data integrity, not software tokens
- Industrial enclosure: rated for -20°C to +65°C, suitable for roof, mast, or external wall deployment
- Connectivity: Wi-Fi and Ethernet, both supported
- Power: 5V via USB-C
- Antenna: external AIS antenna required (not included); performance depends heavily on antenna selection and placement
Setup is genuinely plug-and-play. Connect the antenna, connect power, connect to your network, register at app.mastchain.io. The device handles everything else — AIS reception, GNSS timing, data signing, and submission to MastChain — without requiring Linux knowledge or manual configuration.
MASTNODE STRENGTHS
Performance: Up to 60% more unique vessels detected than equivalent DIY setups under the same antenna and installation conditions. This is not a marginal improvement — it is the difference between a good coverage node and an excellent one, and it directly affects the data value your station contributes to enterprise buyers.
Hardware-grade identity: The ATECC608 secure element provides a level of cryptographic identity assurance that software tokens cannot match. As MastChain's data verification standards develop and enterprise contracts require higher provenance guarantees, hardware-based identity is likely to carry increasing weight in how rewards are calculated.
Reliability: Designed for continuous, unattended operation. Industrial temperature rating, OTA firmware updates, purpose-built hardware stack. For contributors who want to deploy and largely forget, MastNode is substantially lower maintenance than a Pi-based setup.
Network signal quality: Dual-channel simultaneous reception plus PPS timing means each MastNode contributes higher-quality data than a single-channel DIY station. The network's anomaly detection — the layer that flags AIS spoofing, position inconsistencies, and identity manipulation — depends on data quality. Better data means better detection.
MonsPro partnership: MastNode is manufactured by MonsPro, an Istanbul-based industrial hardware firm with experience in infrastructure device manufacturing. Six months of joint field testing preceded the production commitment. This is not a hastily assembled consumer device — it is an industrial instrument designed for the task.
MASTNODE LIMITATIONS
Price: MastNode costs more than a DIY build. The exact retail price was not published at press time, but purpose-built industrial hardware with secure elements and precision GNSS will carry a premium over a £140 Pi build. For contributors in lower-income geographies or those primarily interested in experimenting before committing, the DIY route is the lower-risk entry point.
Availability: The initial production run is limited to 200 units, with first deliveries in June 2026. If you missed the pre-order window, you are on the waitlist for the next batch. A DIY station can be running this weekend.
Less tinkerable: MastNode is a closed-purpose device. It does the AIS job very well, but if you want to run other SDR experiments on the same hardware, or adapt it for unusual deployments, it is less flexible than a general-purpose Pi setup.
Antenna dependency: MastNode's performance advantage assumes a good external antenna. The device ships without an antenna. A poor antenna choice or a bad installation location will close the performance gap with a well-built DIY station quickly. Antenna selection and placement remain the most important single variables in AIS reception quality regardless of hardware.
WHAT THIS MEANS FOR YOUR REWARDS
MastChain's reward model is based on proof-of-coverage — what your station actually sees, how reliably it sees it, and where it is. Raw token emissions are weighted by data quality and coverage value.
All else being equal, a MastNode contributing higher-quality data with hardware-grade identity will likely earn more per unit time than a DIY station with equivalent antenna placement. The performance gap — up to 60% more vessels detected — translates directly to more data points per hour, which translates to more reward weight.
That said, location matters more than hardware. A well-placed DIY station on a headland overlooking a busy shipping lane will outperform a MastNode in an inland location with limited line-of-sight to vessels. The best hardware in the wrong place is still the wrong place.
The practical recommendation for serious contributors: start with DIY to validate your location and understand your coverage area before committing to hardware. If your DIY station shows strong vessel detection in its first weeks, a MastNode in the same spot will meaningfully improve on that baseline and provide better long-term reward economics.
WHO SHOULD BUILD DIY
- You're comfortable with Linux and Raspberry Pi tinkering
- You want to experiment before committing to dedicated hardware
- You already own some of the components
- You're in a location where shipping or import logistics make the MastNode impractical
- You want to understand the full technical stack from the ground up
- You live near a busy shipping corridor and want to get started immediately
WHO SHOULD ORDER MASTNODE
- You want the highest data quality and reward potential from your location
- You prefer a plug-and-play device over a Linux build project
- You're deploying in a demanding environment (temperature extremes, outdoor, unattended)
- You want hardware-grade cryptographic identity for the strongest possible data provenance
- You're a business, marina, harbour authority, or port operator deploying at scale
- You're committed to the network long-term and want infrastructure-grade reliability
THE BIGGER PICTURE
Both paths lead to the same network. Every station — whether a Pi in a Bristol loft or a MastNode on a Norwegian fjord — contributes to the same distributed dataset, the same cryptographic pipeline, and the same mission: replacing unverifiable, consolidated AIS data with something the world can actually trust.
The DIY option exists because MastChain was built on the principle that a true DePIN network should let anyone participate. You should not need to buy proprietary hardware to join a decentralised network. That principle hasn't changed.
MastNode exists because the network's value to enterprise data buyers depends on data quality, and data quality depends on hardware. The two are complementary, not competing.
In a world where AIS spoofing has risen 2,400% since 2023, where shadow fleet vessels are evading US naval blockades in the Strait of Hormuz, and where fourteen European nations have publicly called for "alternative terrestrial radionavigation systems" — the quality of every individual station in this network has geopolitical consequences. Both setups contribute to solving that problem. MastNode just does it with more signal.
