Decentralized physical infrastructure networks (DePINs) are a decentralised network architecture using blockchain technology.[1] Physical Resource Networks are used to collectively operate physical infrastructure like wireless networks, energy grids, and transportation systems, while Digital Resource Networks manage digital resources such as bandwidth and computing power.[2] Participants can earn rewards by contributing data or services to the network.[3]
Platforms and technologies
Some competing standards and vendors for DePIN space include:
Weightless is an open standard, narrowband technology for LPWAN used by Ubiik.
IEEE 802.11ah, also known as Wi-Fi HaLow, is a low-power, wide-area implementation of 802.11 wireless networking standard using sub-gig frequencies.[7]
Types
Depending on their purpose, DePINs can be divided into two types. Physical Resource Networks rely on physical assets such as sensors and wireless networks. They operate at a local scale, and reward users for contributing data or network resources.[8] Digital Resource Networks use digital assets such as bandwidth, computational resources or storage space, and encourage participants to contribute these resources to the network.[9] They leverage a 'long tail' of idle capacity from participants.[citation needed]
