Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Primary language is C, which can be challenging for developers unfamiliar with its nuances and memory management.
Documentation focuses heavily on the primary language (C), while support for other languages like Python and TypeScript is less comprehensive.
Version migrations often require significant code adjustments, such as rewriting chain definitions from v0.1 to v0.2.
Encryption and decryption operations can introduce latency, especially for large datasets or high-throughput systems.
