Sapphire,
The Confidential EVM Paratime

The First and Only Confidential EVM Compatible Runtime

Sapphire Allows for:

  • Confidential state, end-to-end encryption & confidential randomness.

  • EVM compatibility

  • Easy integration with EVM-based dApps, such as NFT, Metaverse, crypto gaming and DeFi

  • Scalability — increased throughput of transactions

  • Low-cost — 99%+ lower fees than Ethereum

  • Cross-chain bridge to enable cross-chain interoperability (upcoming)

Sapphire Compared
to Ethereum

Sapphire offers full EVM and Solidity tool chain support, but it is faster, cheaper, and provides unique privacy-preserving features such as:

The contract state is only visible to the contract that wrote it.
Sapphire offers out-of-the-box contract state confidentiality in an EVM environment, which has never been seen before. Information about the contract can be made private, preserving it from being made publicly visible.

Transactions and Calls are End-to-end encrypted into the contract.
Only the caller and the contract can see the data sent to/received from the ParaTime. This preserves privacy and protects user data from visibility to the whole network.

Privacy-enabled Smart Contract execution
Sapphire supports the creation of confidential Smart Contracts. In this confidential ParaTime, nodes are required to use a secure computing technology called a Trusted Execution Environment (TEE). Data goes into a Secure Enclave along with the smart contract, where the data is decrypted, processed by the smart contract, and then encrypted before it’s sent out again.

A Game Changer to Scale Blockchain to Web3

Sapphire is a first-of-its-kind developer environment created to scale blockchain to Web3. The Oasis Network’s mission is to break through the blockchain privacy paradox, and with the privacy-preserving technology, and familiar developer environment, Sapphire makes this possible.
