Roadmap
2019

Stellar Core is the software that nodes on the network use to achieve consensus and validate transactions. It’s the backbone of Stellar, and the SDF is continually working to make it more efficient, more responsive, and easier to install and maintain. In addition to improving the protocol itself, the core team is also building tooling and resources to ensure the continued health and scalability of the network overall.

Stellar’s social and developer communities are among the most active in fintech, and one of SDF’s primary roles is to support the people and teams who build on and talk about the Stellar network. In addition to publishing more content and focusing on the SDF’s commitment to openness and transparency, the ecosystem team is working closely with the community and vital infrastructure projects to leverage XLM grants so they have the maximum benefit for the network as a whole. We’re also planning a big conference this November!

  • Infrastructure grants (ongoing)
    • Block explorer (stellar.expert)
    • Quorum explorer (stellarbeat.io)
    • SEP-compliant wallet (Lobstr)
    • DEX frontend (Stellarport)

  • Stellar Community Fund Round 2 (Q4)
  • Host a Stellar conference: Meridian took place 11/4-11/5

The SDF maintains Stellar’s codebase, supports the technical and business communities around Stellar, and is a speaking partner to regulators and institutions. In addition to creating and maintaining the technology, products, and relationships outlined above, we also strive to be proactive and transparent, and to grow and foster the talent and teamwork that are at the heart of our organization.
