Generally refers to decentralized technologies that somehow benefit from blockchain-like data structures. For example, you can compost these three technologies to build a decentralized webserver.
- Filecoin & AR Weave: decentralized file storage. Spend tokens to store files, earn tokens by storing others' files.
- ENS (Ethereum Name Service): DNS-like system for addresses.
- Smart Contracts of various sorts (e.g. Ethereum): Similar to perpetual AWS lambda functions. Spend tokens to publish & call functions; earn tokens by executing functions.
The blockchain aspect is merely a way to have verifiable incentives without explicit trust between actors.
