Phala aims to become the privacy protection infrastructure of Web3.0. It is developed based on Substrate and implements confidential smart contracts through the TEE blockchain architecture, which can provide privacy computing services for the Polkadot ecosystem.
Phala is Polkadot's private computing infrastructure. Phala Network is a private computing parachain on Polkadot. Based on a pow-like economic incentive model, Phala releases the privacy computing power of countless CPUs and applies it to the Polkadot parachain, thereby serving other applications such as Defi and data services on Polkadot. The Phala-based applications pLibra and Web3 Analytics have received web3 foundation grants.

Khala Network will use K-PHA as the network token. K-PHA is the Kusama version of the PHA token, which can be exchanged 1:1 with ERC20-PHA and the main network PHA.
