During September 2025, Cacti focused on stabilizing emission calculations in the opentensor/subtensor repository, addressing a critical backend reliability issue. They improved the correctness and safety of the run_coinbase function by refining alpha_in_i handling across price thresholds and reinforcing guards to prevent panics, particularly around division-by-zero scenarios. By reintroducing safe division logic and surfacing invalid conditions with explicit panics, Cacti reduced production risk and improved the predictability of emission values in live blockchain systems. Their work, implemented in Rust and leveraging Substrate, also included code formatting enhancements, resulting in clearer, more maintainable emission logic and a more robust backend foundation.
