Cardano Unveils Mesmo, Native Shared Library for Python, Go, Rust, JavaScript

Cardano has announced the release of Mesmo, a native shared library that implements its core functionality in Python, Go, Rust, and JavaScript without requiring a Java Virtual Machine. According to an official blog post by the Cardano Foundation, Mesmo fills the missing 5% of developer needs that are not covered by existing SDKs.

Mesmo works by taking the mature Java SDK, Cardano Client Lib (CCL), and compiling it with GraalVM Native Image into a shared library with a plain C ABI. This allows developers to access extra features outside of a certain library without having to switch libraries.

In related news, alternative node development continues to gain momentum on the Cardano network. Dingo, developed by Blink Labs, has reached a major milestone by validating blocks accepted by the Mainnet network.

The latest Amaru release introduces improvements to duplex connections, peer management, block fetching, and governance-related functionality. The Amaru node team is targeting a block-producing pre-release from September 29, followed by a beta approximately four weeks later, and first Mainnet block production in Q4.
