Oasis Network is a privacy-first blockchain designed for confidential smart contracts and tokenized data, founded by Dawn Song — a UC Berkeley professor and one of the world's leading computer security researchers. Its ParaTime architecture separates consensus from execution, enabling parallel confidential computing environments that can process sensitive data without exposing it. Oasis uniquely positions itself at the intersection of privacy and data economy. Its vision is a world where individuals can tokenize and monetize their personal data while maintaining control — a fundamentally different approach from the surveillance-capitalism model of Big Tech. Confidential smart contracts can process medical records, financial data, or personal information without any party seeing the raw data. The Sapphire ParaTime provides an EVM-compatible confidential execution environment, making it easy for Ethereum developers to build privacy-preserving dApps without learning new tools.
Dawn Song founded Oasis Labs in 2018, launching the Oasis Network mainnet in November 2020. Sapphire (confidential EVM) launched in 2022, enabling privacy-preserving Solidity development. Partnerships with AI projects, data privacy organizations, and enterprise clients targeted the confidential computing market. The network has focused on privacy-preserving AI training and decentralized data marketplaces.
Oasis separates consensus (the Consensus Layer validates blocks) from execution (ParaTimes process transactions). Each ParaTime is an independent execution environment — some are confidential (using TEE or MPC for encrypted computation), others are standard. Sapphire is the confidential EVM-compatible ParaTime; Emerald is the standard EVM ParaTime. ROSE is the staking token for the Consensus Layer, gas token for transactions, and governance token. Validators stake ROSE and are randomly selected for block production across ParaTimes.
ROSE has a total supply of 10 billion tokens with staking emissions. Staking yields approximately 8-12% APR. The token is used for transaction fees, staking, and governance across all ParaTimes.
Dawn Song is among the most cited computer security researchers — unmatched academic credibility.
Privacy-preserving smart contracts enable use cases impossible on transparent chains.
Sapphire lets Solidity developers build confidential dApps without learning new languages.
Confidential AI training on blockchain data is a unique and growing market opportunity.
Despite strong technology, Oasis has limited DeFi TVL and dApp activity.
Privacy features are technically important but haven't driven mass crypto adoption.
ZK-proof-based privacy (Aztec, Mina) competes with TEE-based confidential computing.
Strong research credentials don't automatically translate to commercial ecosystem growth.
Confidential computing processes data without exposing it to anyone — including the computers performing the computation. On Oasis, smart contracts can work with encrypted inputs and produce outputs without any validator seeing the underlying data. This enables privacy-preserving DeFi, confidential AI training, and secure data sharing.
Monero and Zcash provide transaction privacy (hiding sender, receiver, amounts). Oasis provides computation privacy — smart contracts can process private data while keeping it confidential. Oasis enables privacy-preserving applications (private DeFi, confidential AI), not just private payments.
ParaTimes are independent execution environments on Oasis. Each ParaTime has its own rules, performance characteristics, and privacy properties. Sapphire (confidential EVM), Emerald (standard EVM), and Cipher (confidential WASM) are current ParaTimes. Anyone can deploy custom ParaTimes for specialized workloads.
