PIN Public Index Network

Public Index Network (PIN) is an open index for web3 application metadata. PIN is a proof-of-work cryptocurrency designed to index web3 metadata. PIN also exists as a wrapped token on Ethereum, Binance Smart Chain, and Polygon.

Users and developers can “pin” metadata, permanently and immutably storing it on the network for public use. Pins can then be retrieved and read by any PIN-based application. When combined with its supporting metadata library, the Open Index Protocol (“OIP”), PIN provides a new standard for publishing, indexing, and monetizing any digital content.
