Bandwidth Sharing
Web3 / depin
Bandwidth sharing is a DePIN (Decentralized Physical Infrastructure Network) model where users monetize their unused internet connectivity by allowing others to route traffic through their connection. Participants install software that identifies available bandwidth on their devices and makes it available to the network in exchange for cryptocurrency rewards. This creates a peer-to-peer internet infrastructure layer where supply and demand for connectivity are coordinated through smart contracts and token incentives, reducing costs for users who need additional bandwidth while generating passive income for providers. Example: Sentinel is a decentralized VPN and bandwidth sharing platform built on the Cosmos blockchain where node operators earn SENT tokens by providing bandwidth and privacy-preserving connectivity to users across the network. Why it matters for DePIN: Bandwidth sharing directly challenges traditional ISP monopolies by creating competitive, decentralized alternatives. This reduces internet costs globally, improves redundancy and censorship resistance, and aligns economic incentives so infrastructure providers are rewarded fairly for resources.
