Phala Network Blockchain is a decentralized cloud computing service created based on an infrastructure component that helps participants establish private communications on an open source blockchain network. Its infrastructure integrates a hybrid TEE-blockchain (Trusted Execution Environment) architecture that isolates the code and content of smart contracts deployed within the network from the outside world.The privacy-preserving smart contracts that are coded and executed in the Phala Network environment are known as Phat contracts. Its data is processed in a secure enclave with access restricted to authorized parties, thus enabling cloud-based cross-chain services that help organizations establish communications on a fully decentralized network.In addition, with its blockchain capabilities, Phala Network was able to apply Polkadot XCMP technology. As a Polkadot parallel chain, Phala Network can be used as a cross-chain infrastructure component to provide services to organizations and enterprises on the smart contract blockchain platform, using “$PHA” as the token code.
