Secret Network vs Oasis Network for private smart contracts

Architecture: Combines Intel SGX TEEs with default data encryption for smart contracts (Secret Contracts). Inputs, outputs, and state are encrypted, even from validators.

Key Advantage: Enables general-purpose confidential computation on public data. Ideal for private auctions (e.g., Shade Protocol), decentralized identity, and MEV-resistant DEXs.

Ecosystem Strength: Hosts established confidential DeFi primitives like Shade Protocol (private stablecoins, lending) and Sienna Network (private swaps).

Key Advantage: A proven, live environment for applications requiring transactional privacy (e.g., hiding trade sizes, wallet balances). Lower risk for teams building in this niche.

Architecture: Separates consensus (Consensus Layer) from execution (ParaTime Layer). Each ParaTime (e.g., Emerald EVM, Cipher) can have distinct privacy, VM, and governance models.

Key Advantage: Flexibility and scalability. Developers can choose a privacy model (TEE, ZKP, or none) and VM. Enables parallel execution, reducing network congestion.

Ecosystem Strength: Offers Emerald, a high-throughput, fee-market EVM-compatible ParaTime, and Cipher, a confidential WASM ParaTime.

Key Advantage: Easier migration for Ethereum dApps seeking optional privacy features. Supports a wider vision including confidential AI and data tokenization (e.g., with Oasis Privacy Layer).

Specific advantage: Uses Intel SGX for encrypted computation, with a proven track record since mainnet launch in 2020. This matters for applications requiring strong, hardware-backed data confidentiality for inputs, outputs, and contract state, such as private voting or sealed-bid auctions. The ecosystem includes privacy-preserving DeFi apps like SiennaSwap and Shade Protocol.

Specific advantage: Built-in IBC integration and bridges to Ethereum, Polygon, and BNB Chain. This matters for protocols that need to bring private smart contract logic to assets from other ecosystems. The Secret VRF provides verifiable randomness for cross-chain gaming and NFTs, a feature not natively emphasized by Oasis.

Specific advantage: Offers a dual-layer architecture with the Consensus Layer and ParaTime Layer, supporting multiple TEE types (like Intel SGX) and future-proofing for other technologies. This matters for enterprises or consortia that require configurable privacy levels and may need to adapt to different hardware or regulatory requirements. The Oasis Privacy Layer (OPL) brings privacy to Ethereum dApps.

Specific advantage: The ParaTime design separates consensus from execution, enabling high throughput (up to 1,000 TPS per ParaTime) and low gas fees. This matters for building scalable private applications like confidential AI inference or high-frequency data markets where cost and speed are critical. Partners include Meta and BMW Group for data tokenization use cases.

Specific trade-off: Reliance on Intel SGX creates a centralized trust assumption in hardware manufacturers and is vulnerable to potential future attacks on the TEE technology. This matters for projects with extreme threat models that require cryptographic privacy guarantees without trusted hardware. The validator set must also run specific SGX-enabled hardware.

Specific trade-off: Multiple, independent ParaTimes can lead to liquidity and composability fragmentation. This matters for DeFi builders who need deep, unified liquidity pools. While flexible, the ecosystem is currently smaller than Secret's in terms of live, privacy-focused dApps, requiring more in-house development.

Architecture: Leverages Intel SGX TEEs for hardware-level privacy. Key Metric: Data remains encrypted during computation, even from node operators. This matters for DeFi applications requiring private order books, sealed-bid auctions, or confidential voting where inputs must be hidden from all parties.

Ecosystem Focus: Entirely built around confidential smart contracts (Secret Contracts). Key Metric: Native privacy tokens (sSCRT) and established apps like Sienna Network (private DEX) and Shade Protocol (private stablecoins). This matters if you need deep integration with an existing privacy-native DeFi stack and user base.

Potential Drawback: Relies on hardware security assumptions of Intel SGX, which has faced historical vulnerabilities. Impact: Requires ongoing trust in TEE integrity and remote attestation. This matters for highly adversarial, high-value applications where hardware attack vectors are a primary threat model.

Architecture: Offers both TEE-based ParaTimes (like Sapphire) and a Confidential EVM for broader compatibility. Key Metric: Developers can use familiar Solidity/Vyper with privacy extensions. This matters for EVM-native teams (e.g., from Polygon, Avalanche) seeking to add optional privacy to existing dApp logic with minimal rewrite.

Key Differentiator: Separates consensus and execution layers, enabling high-throughput confidential compute. Key Metric: Pioneers data tokenization via the Oasis Privacy Layer and projects like Nebula Genomics. This matters for enterprise-scale data marketplaces, Web3 gaming, and AI requiring massive parallel private computation and data sovereignty.

Potential Drawback: Privacy is a feature of specific ParaTimes, not the base layer. Impact: Developers must consciously choose and deploy on a confidential runtime (e.g., Sapphire). This matters if you require uniform, chain-wide privacy guarantees by default rather than a selectable environment.
