Oasis Sapphire is a privacy-first, EVM-compatible Layer 1 blockchain utilizing Trusted Execution Environments (TEEs) for encrypted state. It supports confidential smart contracts with flexible privacy levels from fully private to fully public. Sapphire integrates with other EVM chains through the Oasis Privacy Layer for seamless cross-chain confidentiality.

Is Oasis a secure platform?

Security derives from Intel SGX TEEs encrypting contract execution and state, preventing node operators from viewing sensitive data. The network uses a PoS consensus with BFT finality, continuously audited for vulnerabilities. Regular audits, decentralized validators, and the Oasis Privacy Layer ensure confidentiality and resistance against data leaks.

Developers write Solidity or WASM smart contracts with additional privacy features enabled by Sapphire SDKs. dApps deploy contracts via familiar Ethereum tools and optionally integrate Sapphire’s encryption wrappers. Users interact with dApps through standard wallets with enhanced privacy supported by encrypted transactions and free private view calls.

What services does Oasis offer?

Sapphire offers confidential smart contracts, privacy-preserving randomness, encrypted storage, and off-chain confidential computation with ROFL. The Oasis Privacy Layer provides cross-chain privacy for any EVM chain without migration. It supports DeFi, NFTs, DAOs, AI, and gaming with end-to-end privacy and scalability.

Oasis: What is it and Why is it Important?

Primary features

Oasis Sapphire is a confidential Ethereum Virtual Machine (EVM) layer-1 blockchain that empowers Web3 and AI with Smart Privacy. Developers can build EVM-based on-chain decentralized applications (dApps) with smart contracts that are 100% confidential, 100% public, or anywhere in between.

Confidential smart contracts: Utilizes secure enclaves to keep contract state and calldata encrypted by default.
EVM compatibility: Supports standard Ethereum tools like MetaMask, Hardhat, and Ethers.js.
High throughput: Offers increased transaction throughput with 6-second finality and low transaction fees.
Cross-chain interoperability: Enables communication with other ParaTimes and external EVM networks via bridges.
Native privacy features: Includes built-in support for confidential randomness and encrypted storage.

Services

Oasis Sapphire provides a comprehensive suite of services to facilitate the development and deployment of privacy-focused dApps.

dApp development and deployment: Tools and documentation to build and deploy confidential dApps on Sapphire.
Secure enclaves: Execution of smart contracts within Trusted Execution Environments (TEEs) to ensure data confidentiality.
Privacy layer integration: Integration with the Oasis Privacy Layer to add confidentiality to existing dApps on other EVM networks.
Cross-chain bridges: Bridges to enable asset and data transfer between Sapphire and other blockchains.
Developer tools: Support for standard Ethereum development tools and infrastructure.

Work principles

Oasis Sapphire operates on a modular architecture designed to provide scalability, privacy, and interoperability.

ParaTime architecture: Isolates workloads into separate ParaTimes for parallel processing and optimized performance.
Secure execution: Enforces the use of TEEs for all nodes to ensure secure and confidential computation.
Modular execution: Allows for specialized execution environments tailored to specific application needs.
Privacy-first design: Prioritizes data confidentiality and user privacy in all aspects of the network's operation.
Community governance: Incorporates decentralized governance to guide the development and evolution of the network.

User benefits

Users of Oasis Sapphire can expect enhanced privacy, security, and performance in their interactions with dApps.

Enhanced privacy: Confidential smart contracts ensure that user data and transactions remain private.
Secure interactions: Execution within TEEs protects against unauthorized access and tampering.
Low-cost transactions: Reduced transaction fees compared to other EVM networks.
Fast transaction finality: Quick confirmation times enhance user experience.
Cross-chain compatibility: Seamless interaction with dApps on other EVM networks through bridges.
