Extensive Documentation
Provides rich resources for integrating and extending Zama’s functionalities.
Pros
- +Enhanced Data Privacy: Allows for data analysis and machine learning while preserving user privacy.
- +Ease of Use: Simplifies FHE deployment with user-friendly libraries and frameworks, reducing the need for deep cryptographic expertise.
- +Versatile Applications: Suitable for various industries, including finance, healthcare, and the public sector.
- +Active Community and Support: Provides robust support through documentation, GitHub repositories, and an active community.
Cons
- −Performance Overhead: FHE can introduce slower performance compared to operations on unencrypted data.
- −Resource Intensity: Requires significant computational resources, which may be challenging for smaller organizations.
- −Learning Curve: Initial setup and integration into existing systems can be complex.
Limitations & when to consider alternatives
Known limitations
- Encrypted control flow constraints. Concrete does not support if or while conditions that depend on encrypted values.
- Floating-point limitations. Concrete does not support floating-point inputs or outputs; encrypted values use supported integer precision.
- Encrypted bit-width limits. Encrypted values have a maximum bit width, and exceeding it causes an error.
- Confidential-token decimal limit. Confidential wrappers currently support a maximum of six decimals.
- Unsupported token types. Non-standard fee-on-transfer and deflationary tokens are not supported by confidential wrappers.
Look elsewhere when
- You need a conventional general-purpose blockchain platform.
- Your application requires unsupported encrypted control flow.
- Your token requires more than six confidential decimals.
