Kulupu is a sister project related to Solri. Kulupu's goal is to create a working proof-of-work blockchain built using unmodified Substrate blockchain framework. Compared with Solri, Kulupu aims to take a more practical approach of an on-chain governed self-updating blockchain, while Solri maintains the ideal minimalist blockchain design.
The consensus engine for Kulupu is the CPU mining algorithm RandomX. For initial launch, the emission rate is fixed at one coin per second. This, however can be changed using hard fork or on-chain governance in the future.
