Cardano Leios Update Go Make Musashi Testnet Start Afresh

Input Output latest Leios pre-release dey require say Musashi Dojo testnet restart because di endorser-block format no dey compatible with earlier versions. Di update land during Fire, di phase wey dey test how Cardano proposed throughput upgrade go behave when load dey increase.

New Leios Block Format No Dey Compatible With Older Versions

Ouroboros Leios dey expand Cardano transaction capacity by adding extra endorser blocks join di existing Praos chain. Dem dey reference transactions wey committee of stake pools go validate and vote on. Certificate go allow those transactions enter di ledger.

Di design add extra capacity for ADA transfers and application transactions. Endorser blocks get separate distribution and validation processes, so participating nodes must follow compatible communication rules.

Node wey dey run rc-2026w42 no fit exchange endorser blocks with earlier versions or read their chains. According to di release notes, operators must delete both di local chain database and Leios databases before dem go synchronize di restarted network from genesis.

Certification Don Move One Slot Earlier

Block producers fit certify endorser block immediately after di required announcement, voting, and diffusion periods don finish. With di default parameters, e fit happen after 14 slots, one slot earlier than previous releases.

Di change align di prototype with CIP-164 and di upstream node header-validation rules. Di threshold define di earliest time wey certificate fit enter; actual inclusion still depend on whether eligible block show for production.

Certification across epoch boundary no dey allowed again. Nodes go reject headers wey dey try certify endorser block wey dem announce for previous epoch, and block producers no go create that kind certificate again.

Di release still fix one prototype bug wey fit allow transaction wey get failing Plutus script to spend im script-locked inputs after dem don certify im endorser block. Di correction preserve di script-validity flag inside di transmitted transaction encoding. E still require fresh validation when di protocol version wey dem use vote differ from di version wey dem take check di transaction before.

Musashi Fire Dey Test Cardano Initial Parameters

Input Output dey operate Musashi Dojo, and independent stake pool operators dey run Leios-enabled block producers and dey participate for consensus. Test ADA and delegation dey support their involvement.

During Fire, traffic go dey increase step by step to set sustainable operating levels, expose software issues, and evaluate protocol settings. Di testnet still give application teams environment to check wallets, indexers, and other tools against Leios.

Intersect October 17 update report say Musashi don pass Preview and Preprod for network size and geographic distribution. Di development team hold two open sessions during testing on October 15, and di findings go help set di initial parameter settings for Cardano mainnet.

Operators still get new cardano-cli query leios-committee command to inspect di voting committees for di current and next epoch.

Committee information wey query stake-snapshot bin dey return don move go that dedicated query, to match di release changes to certification timing and epoch boundaries.
