DePIN stands for Decentralized Physical Infrastructure Network. It describes systems where real world infrastructure is built, operated and expanded by a distributed community rather than a single company.

In a DePIN model, individuals deploy small devices that perform useful work in the physical world. These devices might measure signals, provide connectivity, store data or capture information. The network then uses a blockchain based layer to coordinate participation and reward the people who contribute.

The idea is simple. Instead of one organisation funding and maintaining every piece of infrastructure, thousands of participants share the load. The network grows faster, reaches more locations and becomes more resilient because it is not reliant on a central authority.

For Mastchain, DePIN provides a way to expand AIS coverage through a global community while keeping data verification transparent and fair. Each receiver contributes to the network’s usefulness, and the blockchain ensures that contributors are recognised for the value they provide.

If you’d like, I can now write the follow up section that explains why Mastchain is a DePIN and how it differs from traditional AIS networks.
