Disclaimer: These are planning documents. The functionalities described here may be unimplemented, partially implemented, or implemented differently than the original design.


The following is a tentative roadmap to future releases.

Splinter v0.7

Splinter v0.7 provides a robust Scabbard service with an architecture to support high availability work moving forward. The high availability journey begins here because transaction processing involves technically complex parts of the system: a merkle tree with provable state agreement and consensus algorithms.

The release will also include an orders of magnitude increase in txn/sec that Scabbard can processes at both a circuit level and per process/node.

Past Roadmaps

The following are roadmaps for completed past releases.

Splinter v0.6

Splinter v0.6 addresses critical areas required for running Splinter in production, which brings Splinter to a huge milestone: v0.6 is expected to be suitable for low-volume production environments which can withstand some amount of downtime for upgrades or single-point-of-failure issues.

Additional Information

Management of the Roadmap

The roadmap is a collaborative effort derived from both agile community feedback and long-term vision. Communities building other open source projects which are built upon Splinter, such as Grid and Sawtooth, have a substantial impact on the roadmap. Non-public projects also have a substantial impact.

Please join the community!
