…l Orchard support only, without supporting and enabling ZSA features.
This commit introduces basic support for Transaction version 6 (Tx V6). This initial implementation treats Tx V6 as a simple copy of Tx V5, without yet integrating ZSA-specific features or the new transaction structure. - Added a new V6 variant to the Transaction enum in the zebra-chain crate. - Updated relevant code to handle the new V6 variant. Note: Tests and additional adjustments are still pending, and will be addressed in subsequent commits.
…py V5 behaviour for now)
…(without unit tests fixing for now). - Refactored `ShieldedData` and `Action` structures to be generics parameterized by Orchard flavor (`OrchardVanilla` or `OrchardZSA`), enabling support for both Orchard protocols in Tx V6. - Introduced a `burn` field in `ShieldedData` to support ZSA, with unit type for Tx V5 and a vector of burn items for Tx V6. - Modified `Transaction` enum methods (orchard_...) to handle generics properly, ensuring compatibility with both Orchard flavors. - Implemented serialization and deserialization for Tx V6 while avoiding code redundancy with Tx V5 wherever possible.
… with the upstream halo2/librustcash/orchard/sapling versions
1. Introduced new type `Burn` that wraps `Vec<BurnItem>`, implemented serialization/deserialization for it - put it into `orchard_zsa/burn.rs`, also moved `NoBurn` there from `orchard_flavor_ext.rs` for better code structuring. 2. Renamed the `EncryptedNoteTest` trait to `TestArbitrary` in `orchard_flavor_ext.rs` and used it to constrain `BurnType` as well. 3. Renamed `serialize.rs` to `common.rs` in the `orchard_zsa` folder. 4. Refactored transaction generation strategies for V5 and V6 in `transaction/arbitrary.rs` and `orchard_zsa/arbitrary.rs` to incorporate the new burn handling and proper issuance handling.
