This week, the ledger team implemented validation and application of Leios endorser blocks, which carry transactions alongside ranking blocks. The team also exposed a certificate-validation interface and removed owner-signature requirements for pool updates that only change BLS keys.
For Dijkstra, the team introduced a separate mempool tran...
CORE TECHNOLOGY
This week, the ledger team put most of its effort into Leios and the block header changes that support it. Each protocol now has its own block header interface, which can be specified era by era, and Dijkstra headers no longer rely on a self-reported protocol version. On the Leios side, the ledger now selects the Leios committee at the epoch...
CORE TECHNOLOGY
This week, the consensus team split the Leios prototype's database into two files, one for data that can still be rolled back and one for settled data, with certified Endorser Blocks moving from the first to the second in the background; operators can put each file on its own disk. Garbage collection now runs in two paced steps, marking rows...
CORE TECHNOLOGY
This week’s update from the ledger team covers four weeks of work. The headline item: Dijkstra's batch validation now runs Plutus scripts for sub-transactions and counts their execution budgets, closing a gap where sub-transaction validators and minting policies went unchecked and their costs escaped transaction and block limits and script f...
