Hi jan, it is great that you have noticed my little pet project, haha.
Spora is an very experimental GhostDAG-based cell chain inspired by a thesis by Yonatan et al in 2021, and the core design goal is to stay strictly isomorphic to the CKB cell model rather than introducing a different programming model.
The reason I started it was to explore whether the cell model could potentially scale to much higher throughput while preserving the same underlying semantics. In principle, a design like this could become an interesting direction for the future of cell-based systems if the hard problems are solved well.
Right now, though, it is still very much an experimental system. The main bottlenecks are storage blowup and, related to that, how far execution parallelization can be pushed in a clean and safe way. If those problems can eventually be solved well, then I think this line of exploration may have real long-term value for the cell model.
At the moment, most of my active work is still on CellScript rather than Spora.
The repository is here: https://github.com/tsukifune-kosei/Spora
It can already run basic transfer transactions and simple CellScript contracts.
If you have any thoughts or suggestions on the direction, I would genuinely love to hear them.
