# Builder Program

Builder Program attracts and supports SatoshiNet ecosystem builders. It serves long-term public goods, real applications, and verifiable infrastructure, not short-term campaigns.

## Current Priority Builders

## What Builders Can Create and Receive

| Builder                        | Value Created and Received                                                                                                                          |
| ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| BTC community                  | Own brand, user entry, application rules, community relationships; can design application-layer service fees                                        |
| Developer                      | Application revenue, deployment and integration revenue, public case studies, possible future grants                                                |
| Mining Node                    | GAS fees generated by actual block production and execution; other rewards follow final protocol rules                                              |
| Core Node                      | Includes Mining Node capability and provides STP service; can receive block-production fees, while extra STP service fee model remains under design |
| Indexer / RPC / Explorer       | API, SLA, hosting, and enterprise integration revenue                                                                                               |

Current Builder Program mainly provides open-source code, testnet, technical review, deployment support, and joint showcase. Cash grants are not guaranteed; they may later come from dedicated sponsorship, grants, or foundation programs.

## How to Apply

Application material should include project goal, team background, target users or community, required modules, current status, first testnet milestone, existing code or evidence, risk boundaries, and questions requiring SAT20 Labs review.
