Cardano’s Leios Scaling Work Advances, but November Update Signals No Mainnet Launch
Summary
Cardano’s November 6 development report outlines ongoing work on its Leios scaling design, including endorser-block production, chain-selection checks and adaptive endorsements in a prototype. A prior prototype reduced an internal certifying-block operation from up to 0.9 seconds to milliseconds, but this is not a mainnet confirmation-time improvement. Other updates include lower memory use for ledger snapshots, Hydra monitoring and reliability work, and Plutus cost models and conformance tests. These are engineering developments, not deployed upgrades or proof of lower fees, greater adoption or guaranteed throughput gains; further testing and a path to releases remain necessary.
