Blockchain Confidentiality by Trusted Computing

Confidencial data exchange protocol

Phala.Network guarantees the reliable execution of smart contracts while keeping the data secretly. Confidential contracts run in miner nodes with Trusted Computing capable hardwares, which guarantees the secrecy of the contract data.

Trustless Execution with TEE

The hardware enclave is the key of confidentiality and the integrity.

Hardware Level Isolation

Trusted computing capable CPUs can provide the low level isolation that can even resists OS and hardware level attacks.

Trustless execution

Users can only interact with confidential contracts in authorized ways. Hackers can't read or write the protected contract data in any way.

Multi hardware standard suported

Phala.Network will support multiple TEEs including Intel SGX, AMD SEV, and ARM TrustZone.

Confidential computation layer2

Phala Network can offer the ability of confidential contract to any blockchains because the protocol is natively cross-chain interoperable.

Smart contract with secrets

Phala Network implements Confidential Smart Contract with a TEE-Blockchain Hybrid Architecture.

Verifiable yet privacy-perservinng

Phala guarantees the reliable execution of smart contracts while keeping the data secretly. With Remote Attestation protocol, users can verify that all the transactions are executed in a trusted environment securely.

Don't trust, verify

All the execution can be traced to a set of cryptographic evidences. The evidences are produced and signed by the trusted computing protocol (e.g. Intel SGX) and available on the blockchain for users to verify.

Composability & Interoperability

Phala Network is the first confidential contract network with composability and interoperability. 80% of the top 10 contracts on Ethereum invokes or interact with other contracts.

Cross-chain computation

Phala Network is based on Substrate. It offers confidential contract capability to other blockchain with Polkadot's XCMP. Eventually all the blockchains can share our infrastructure and reduces computing power costs.

Products on Phala

01. Take back the control for your data!

Web3 Analytics

By providing a deadly easy-to-use product, we invite you to turn your website fully Web3.0-ready without pain. W3A is a decentralized analytics system which values users privacy. W3A is completely open source. Phala Network enforces user's ownership of their personal data. Therefore, we eliminated data leakage or abusing.

02. Confidentiality for everyone

Confidential computation Layer2

We build pLIBRA, a privacy-preserving layer for Libra, based on Phala Network confidential contract. We would like to help other blockchains to get confidentiality as well. pLIBRA is a W3F Grant winner.

“As a evangelist for web3.0, winning W3F grant is just the beginning for Phala. We joined the Substrate Builders' Program to make Phala a contributor to Kusama or Polkadot Parachain !”
Hang Yin
Ambassador of Polkadot

Polakdot is a scalable, interoperable & secure network protocol for the next web.

Polkadot is a network protocol that allows arbitrary data—not just tokens—to be transferred across blockchains.This means Polkadot is a true multi-chain application environment where things like cross-chain registries and cross-chain computation are possible.

Phala Network is a Web3 Foundation Grant project.

In support of our mission, the Web3 Foundation grants program funds software development, research, technical education and community engagement efforts in and around the field of decentralized software protocols.

Phala Network is Substrate based and a member of Substrate Builders’ Program.

From Parity Ethereum, Parity is building the most advanced Ethereum client, to Polkadot, the next-generation interoperable blockchain network. Parity builds the cutting edge of Web 3.0.
