The next large milestone for GRAFT is implementing checkpointing (a way to achieve finality and avoid various double spend exploits between the layers of the multi-layer blockchain).

We have been looking at checkpointing solutions from Dash, LOKI, and Ethereum Casper. All of them use slightly different approaches for validator quorum selection, conflicting checkpoints resolution, revision attacks, catastrophic crashes, etc. Our goal is to pick the best model for GRAFT by leveraging the work that’s been done on these other platforms.

In the next couple of weeks we will be working on putting together a proof-of-concept for GRAFT checkpointing, at which point we will publish the design to collect comments and proceed with full implementation.

On a separate subject, one of the community devs who was interested in helping Slava with Lyra has stepped up to continue Lyra development and has already built an impressive showcase app, which he’s planning to publish shortly. Little too early to “count the chickens”, but looking quite promising that Lyra development will continue.
