Harmonic Laboratories (HLabs for short) is an R&D firm born and focused solely on the Cardano ecosystem.

Harmonic Laboratories supports and maintains a considerable portion of the TypeScript tooling for the Cardano ecosystem, which the majority of Cardano developers use, either directly, or indirectly via other libraries that depend on code written and maintained by HLabs.

The mission of HLabs is for true decentralization to become the baseline of application development, not only a nice-to-have feature.

This proposal funds [Gerolamo](https://github.com/HarmonicLabs/gerolamo), the first production-ready Cardano node that runs **in the browser**, at 5 FTE.

Cardano's eUTxO design and low-footprint protocol make it the only major blockchain where a fully-validating, in-browser node is technically realistic. This is not a research demo or a stripped-down SPV client; it is a real, fully-validating node. Shipping it turns a latent property of the protocol into a Cardano-specific competitive advantage that no other ecosystem can replicate without redesigning their base layer.

A separate proposal funds [Pebble](https://github.com/HarmonicLabs/pebble) and ongoing TypeScript tooling maintenance at 5 FTE and is voted on independently.

### Duration & Milestones

This proposal spans over **12 months**, throughout which there will be several deliveries and demos. The key delivery is:

- a production-ready light node that runs in the browser ([Gerolamo](https://github.com/HarmonicLabs/gerolamo)).

### Total Budget Ask

The estimated USD budget is of **`$1,000,000`** (or **`₳4,000,000`**) + 15% in refundable contingency (**`₳600,000`**); for a total ask of **`4,600,000 ADA`**.

The first node in the browser; a Cardano USP

Cardano Foundation

While we appreciate Harmonic Laboratories and the unbundling of this initiative, the $1.15M ask for a browser-based node currently lacks broad market validation, faces significant technical constraints, requires more rigorous acceptance criteria, and is missing key architectural design decisions.

In line with my past vote, I'm voting YES for Gerolamo. This in-browser light node gives Cardano trustless on-device validation for dApps/wallets.
