Chapter 1: Introduction to PoPW

The Proof of Physical Work (PoPW) protocol encapsulates tangible use cases by rewarding users for completing verifiable tasks in the real world, such as setting up a 5G hotspot.

In discussions surrounding blockchain and cryptocurrencies, explaining practical applications to those unfamiliar with the technology can be challenging. This difficulty often resurfaces during market downturns, where critics are quick to highlight the vulnerabilities of the blockchain ecosystem. Many dismiss the potential of cryptocurrencies as alternative payment methods due to their volatility and limited scalability.

Although some critiques are valid, it’s essential not to dismiss this innovative technology entirely, as it remains in its developmental infancy. Numerous projects indicate a bright future for blockchain, showcasing features like decentralized currency, the absence of central authority, permissionless protocols, peer-to-peer micropayments, and enhanced financial inclusivity.

Familiarity with Proof of Work (PoW) and Proof of Stake (PoS) protocols is common, particularly since PoW is foundational to Bitcoin, while Ethereum is transitioning to PoS. Most advancements in the blockchain space have concentrated on digital community coordination and economic systems; however, emerging tokens are facilitating innovation in capital formation and human collaboration, extending into the physical realm.

Multicoin Capital has coined the term “proof of physical work (PoPW)” to describe this new avenue. This framework encourages individuals to engage in verifiable tasks that contribute to the development of real-world infrastructure, signaling the emergence of PoPW as a new frontier within the blockchain landscape.

Section 1.1: Understanding Infrastructure Networks

The PoPW system validates device status and rewards users based on established criteria, such as deploying a 5G hotspot.

As illustrated in the infographic above, infrastructure networks can be categorized into fungible and non-fungible types. Fungible networks utilize hardware that is location-agnostic, meaning their services are not dependent on server location. Conversely, the positioning of a wireless network hotspot is critical, making this type of hardware fungible.

Currently, many protocols in this domain are being developed as layer 1 solutions. The PoPW sector can be broken down into four main categories: Wireless Networks, Mobility, Environmental, and Compute & Storage. For instance, Helium and Pollen Mobile offer token rewards to hotspot operators who extend network coverage for IoT and 5G.

Subsection 1.1.1: Notable Projects in PoPW

The Hivemapper Network is a decentralized mapping solution created by contributors using dashcams, while the DIMO Network allows users to earn rewards by connecting hardware devices to their vehicles and sharing that data. In the environmental sector, PlanetWatch aims to establish a global air quality monitoring network to pinpoint pollution hotspots, rewarding community members for their contributions.

Lastly, Filecoin is recognized for its decentralized storage network, offering an efficient source of low-cost distributed cloud storage, where users can earn rewards by providing storage space on their machines. Arweave operates similarly to Filecoin but focuses on the challenge of long-term data retention.
