Utilize a blockchain-based smart contract platform where data access and computation requests are processed in a decentralized manner, ensuring data privacy through cryptographic guarantees.

Integrate an existing zero-knowledge proof library into the data access layer of the platform, ensuring that all data requests are validated through zero-knowledge proofs without revealing sensitive information.

Develop a custom protocol based on homomorphic encryption, allowing computations on encrypted data without revealing the data itself or the computation results to the computing entity.

Employ a trusted execution environment (TEE) for sensitive computations, where data is decrypted and processed in a secure enclave, providing cryptographic proof of the computation‘s correctness without exposing the underlying data.
