Developers have integrated major components of Cardano's scaling upgrade, but unlocking its full capacity will require multiple governance votes and stake-pool participation.

Cardano developers have merged key Leios code as the network pursues a planned 15-fold increase in transaction capacity.

The blockchain's consensus team integrated Praos2, which combines Cardano's existing consensus protocol with the Leios scaling system, into its main development branch, according to a development report.

The team also merged LeiosNotify and LeiosFetch components, which help network nodes exchange information needed to process additional transaction batches. Work on selecting and retrieving those batches, known as endorser blocks, remains outstanding.

The progress comes as developer Input Output (IOG) prepares to introduce Leios through Cardano's forthcoming Dijkstra hard fork, targeting an initial three-to-fivefold increase in processing capacity.

Under its rollout plan, IOG intends to raise capacity to between 10 and 15 times the network's current ceiling through at least two subsequent adjustments.

However, those increases will depend on performance testing and separate governance approvals, leaving the timing of the network's full scaling ambitions uncertain.

The latest software progress brings Leios components closer to integration, although Cardano has yet to begin testing Dijkstra's new protocol rules on its public testnet.

On Oct. 24, Intersect, the member-based organization tasked with maintaining the network's continuity, reported that the testnet, restarted three days earlier, was operating under Cardano's existing Conway rules using node version 11.1.3.
