DePIN Explained: What Are Decentralized Physical Infrastructure Networks?
Too Long; Didn't Read
DePIN (short for Decentralized Physical Infrastructure Networks) extends Web 3--the decentralized internet built on blockchains, cryptocurrencies, and smart contracts--to physical infrastructure and services like energy networks and ride-sharing. Messari, an independent crypto research firm, estimates DePIN’s Total Addressable Market to be $2.2 trillion, growing to $3.5 trillion by 2028. However, DePIN's theoretical market size is the entire non-digital economy, which, according to the World Bank, is nearly $90 trillion.
