What’s in the Box
MastNode is delivered with everything you need to begin deployment quickly and reliably. Each package includes the core hardware and essential components required for stable operation and seamless integration into maritime AIS data infrastructure.
MastNode Device
The industrial-grade AIS infrastructure node, engineered for continuous data reception, secure processing, and network contribution.
Antenna
A 1.2 m AIS antenna featuring a modular design with two 60 cm screw-together sections for easy transport and installation. Provides 5 dBi gain for reliable AIS reception and transmission, with a low SWR of 1.2 to ensure efficient signal performance.
Cable
A 10-meter RG58 antenna cable designed for stable signal transmission between the antenna and the device. Durable construction ensures consistent performance in marine and outdoor environments.
USB Type-C Power Cable
A USB Type-C power cable for supplying power to the device. Supports stable power delivery when connected to a compatible power source.
How it Works
AIS signals are received
Vessels continuously broadcast AIS messages containing position, movement, and identification data. MastNode receives these signals simultaneously on both AIS channels, ensuring reliable and complete data capture.
Data is processed and timestamped
Incoming AIS data is processed locally on the device. Integrated GNSS with PPS provides accurate positioning and precise time synchronization for every data packet.
Secure transmission to the network
Processed data is securely transmitted via Wi-Fi or Ethernet using standard network protocols. Hardware-based cryptography ensures data integrity and trusted device identity.
Contribution to the decentralized network
MastNode delivers validated AIS data to the MastChain ecosystem, where it becomes part of a decentralized maritime data infrastructure and supports real-time and analytical use cases.

Where can I find installation and configuration guides?
Detailed installation and configuration instructions are available in the official documentation, which can be downloaded from the Documentation section of the website.
About Mastchain
MastChain decentralizes maritime data by turning real vessel signals into an open AIS network where anyone can contribute coverage and earn tokens.
Maritime activity shapes world trade, energy, security and finance. Yet the data behind it remains fragmented and controlled by a few. MastChain is rebuilding this foundation as a decentralized network where anyone can contribute coverage, earn tokens and take part in a new global data economy. Our mission is to bring the world’s oceans onto an open, permission-less layer powered by DePIN. By turning real vessel signals into a cryptographic data stream, MastChain creates a transparent and dependable resource for the entire Web3 ecosystem. It is a chance for web3 crypto users to participate in an infrastructure project with real utility, lasting value and the potential for long term rewards.
