Prolly: Content-Addressed Ordered Map Using Prolly Trees

A new open‑source project called **prolly** has been added to the GitHub ecosystem by the user *crabbuild*. The repository, available at <https://github.com/crabbuild/prolly>, was highlighted on the Hacker News “news” section (item 49325458) where it currently holds 11 points and has yet to receive any comments. The project is written in Go and aims to provide a lightweight framework for constructing persistent, versioned data structures, drawing inspiration from the “prolly” tree concept used in modern database systems.

The library offers a set of utilities for building and manipulating immutable trees that can be efficiently stored and queried. It exposes a simple API that allows developers to create nodes, apply updates, and serialize the structure for durable storage. The design emphasizes minimal dependencies and low memory overhead, making it suitable for integration into larger projects that require versioned data handling or conflict‑free replicated data types.

Early reception on Hacker News indicates modest interest, with 11 up‑votes and no comments to date. As the project remains in its initial release phase, the community will likely monitor its development for potential adoption in database tooling or other applications that benefit from persistent data structures.
