Cardano advances Leios work with adaptive endorsements in new prototype

NewsBTC reported that a Cardano development update dated November 6 covered Leios, where work advanced on the main development branch. The update described progress on endorser-block production, chain-selection certificate checks and vote relaying.

The newest prototype, rc-2026w44, added adaptive endorsements, which the update says can shrink endorser-block sizes when votes are low. The earlier prototype, rc-2026w43, cut the time to forge certifying blocks to milliseconds. The update notes that the 0.9-second forging figure is internal and does not reflect user wait time.

Other project updates also appeared. An ouroboros-consensus update lowers memory use for ledger snapshots. The Hydra team's update, which covers October 26 to November 1, reports monitoring and persistence improvements but no new release. The Plutus team finalised cost models and added 65 Value conformance cases.

Leios remains in development and has not been deployed to mainnet, the update states. The Leios changes described above therefore remain on development branches rather than running on the live network.
