Cardano’s 6 November 2026 development update reported progress on its Leios scaling design, including endorser-block production, chain-selection checks and vote relaying. The work remains in development; it is not a mainnet upgrade or proof of higher throughput on the public network.
The report said prototype rc-2026w44 added adaptive endorsements that can reduce endorser-block sizes when votes are insufficient. An earlier prototype cut an internal certifying-block forging operation from as much as 0.9 seconds to milliseconds, but that figure is not a mainnet user confirmation time. A separate Hydra update covering 26 October to 1 November described monitoring improvements and fixes, but announced no new Hydra release.
