About¶
The Polkadot Tech Stack is a subset of the Web 3.0 Tech Stack, which consists of the open-source technologies contributing to and relying on Polkadot. It is meant to be used for decentralized application (Dapp) development within numerous verticals, including DeFi, Gaming, Provenance and many others not pictured below.
