Time to value

Moderate Setup (1-3 hours to deploy basic contracts; more for AI workloads)

You can use Phala Network when you need to run sensitive computation—AI inference, confidential smart contracts, private data analytics—without exposing internal logic or data. It deploys TEEs so that inputs, outputs, and even intermediate states stay encrypted, while still letting the blockchain verify correctness. It works well for developers building secure dApps, enterprises needing privacy guarantees, or AI/ML teams that want to run workloads off-chain with on-chain trust.

What Phala Network does

Run smart contracts in trusted hardware that hide internal statesDeploy AI models and inference tasks off-chain with privacy guaranteesBuild compute heavy workflows (e.g. ML, analytics) with verifiabilityUse TEEs to ensure inputs/outputs aren’t leaked even during executionProvide decentralized compute providers / nodes that supply TEE hardwareEnable governance and staking via native token (PHA) for securityTrusted Execution Environment (TEE) for confidential computationPhat Contracts: combining off-chain compute with on-chain smart contract controlDecentralized cloud compute infrastructure via Phala Cloud / DstackGPU TEE for AI model serving with privacyStaking and governance via PHA token; nodes must stake and are slashed for misbehaviorCross-parachain & cross-chain compatibility in Polkadot ecosystem
