Pebble + Gerolamo - HLabs 2026 Budget
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. ### Duration & Milestones This proposal spans over **12 months**, throughout which there will be several deliveries and demos. Amongst the key deliveries, we note: - maintenance for an upcoming hard fork; - a production-ready light node ([Gerolamo](https://github.com/HarmonicLabs/gerolamo)); - a production-ready, imperative and efficient, programming language for smart contracts ([pebble](https://github.com/HarmonicLabs/pebble)). ### Total Budget Ask The estimated USD budget is of **`$2,250,000`** (or **`₳6,428,571`**) + 25% in refundable contingency (**`₳1,607,143`**); for a total ask of **`8,035,714 ADA`**.
Reasoning
Written after the vote was cast
What this asks for, and from whom
8,040,000 ADA for the Pebble and Gerolamo HLabs 2026 budget, covering TypeScript tooling and the TypeScript Cardano node.
What would have to be true for this to be a good use of treasury funds
Client diversity and a real TypeScript path both matter. A second node implementation in a language most developers already know is genuine decentralization work rather than decentralization talk.
What specifically concerns me
Annual budgets bundling several projects make it harder to judge each piece on its own merits. I would rather see the node and the tooling stand or fall separately.
What I am asking of the proposer if this passes
It was dropped. Split future asks by project with delivery milestones each. Gerolamo reaching block production parity is a genuinely important milestone for this ecosystem and it deserves its own case.
