People have tried, but they’re hard — and TLAs tend to show up. (At least from stories I heard; before my time.)

But they’re doing a crypto one too — maybe that’ll work better.

Familiar DePIN initiatives include Helium, a Decentralized Wireless Network from 2019, Filecoin or Arweave for Cloud Storage.

Practical implementation requires addressing challenges in scalability, error correction, and the development of quantum-resistant protocols. Collaborative efforts among researchers and industry experts are crucial to harnessing the full potential of quantum computing in network and communication technologies. In my research, I found projects like Helium, Weaver Labs, IOTA, Streamr Network at the forefront of this movement. With technological advancements, it will be interesting to see which one of them will rise as a dominant factor in the blockchain space when it comes to network coverage and communications.

The switch of Helium from its own blockchain to Solana in 2022 was so smooth that, as Noah Prince, Head of Protocol Engineering at Helium, put it: “you didn't hear about it because nothing happened.” This migration exemplifies the "Only possible on Solana" hallmark, showcasing the network's capacity for seamless integration and robust support for decentralized systems like DePIN. This move enabled user-hosted wireless networks to thrive, offering economical solutions while leveraging Solana's low-latency, high-throughput capabilities.

Check out https://realtps.net/ — the Hedera network uniquely offers a service called the "Hedera Consensus Service" which allows you to write immutable, verifiable, consensus timestamped data to the ledger for $0.0001 per message; it's very similar to what https://streamr.network/ is doing, but with real-world adoption.
