High level summary​

This period marks a very nice milestone for the Ledger team. We have finalized CIP-118 - Nested Transactions with drastic simplifications through reliance on CIP-112 - Observe script type and CDDL specification with changes to the transaction. This step puts it in the ready state for the final reviews. Once merged it will conclude the last point on the first milestone listed in the Nested Transaction proposal. Furthermore we have also implemented the distinction between sub-transactions and the top level transaction in such a way that will allow us reuse most of the existing Ledger functionality for transaction validation, regardless of the level. This point takes us right to the finish line of having the second milestone completed as well for the Nested Transaction proposal that was promised by the Ledger team. We expect this milestone to be finalized in the next couple of days.

Beside significant progress on Nested Transactions we have also: implemented a proper solution for preventing invalid serialization for a few obscure edge cases in a transaction, tackled some outstanding tech dept and expanded our test suite.

High level summary​

This period Ledger team has progressed further with CIP-112 implementation, in particular we've defined a new type of native script that allows enforcing a plutus script to be executed as part of transaction validation. Besides that we've made some improvents to the Ledger interface for downstream users, put some effort into test suite organization and applied some fixes to our CI/CD configuration.

High level summary​

This period Ledger team has implemented an improvement to withdrawals predicate failure reporting, that will become available with next intra-era hardfork. We've also experimented with a potential representation in Haskell for transaction levels relateed to CIP-118: sub-transactions vs top level transactions. Besides that we did some more code cleanup and made further improvements to the test suite.

Aside from development work there was Ledger team presence at the Node Diversity workshop, which included relevant people from all of the alternative Node implementations that are currently under development.

We've also finished up features necessary for the next intra-era hard fork. Besides that we did some general improvements, such restructure of how stake pools are represented in the state and test suite organization. We've also made a release of all ledger packages and prepared them for the upcoming cardano-node-10.6 release.
