* Set the tip height and previous hash for arbitrary genesis blocks
And cleanup the ledger strategy interface.
* Generate partial chains with correct previous block hashes
* Provide the network value from the PreparedChain strategy
* Clarify the finalized state assertion that checks the genesis block
* Make arbitrary block chains pass some genesis checks
Use the genesis previous block hash for
- the first arbitrary block in each chain, and
- individual arbitrary blocks.
This setting can be adjusted by individual proptests as needed.
* Rename RootHash to Commitment based on ZIP-244
Interactive replace using:
```sh
fastmod RootHash Commitment
fastmod root_hash commitment
fastmod root_bytes commitment_bytes
git mv zebra-chain/src/block/root_hash.rs zebra-chain/src/block/commitment.rs
```
All replacements were accepted.
* rustfmt
* Comment and format cleanups after interactive replace
* Distinguish Sapling tree roots from other tree roots
* Add the NU5 BlockCommitmentsHash variant to block::Commitment
This change parses the hash, but does not perform validation.
* Validate reserved values in Block::commitment
- change Block::commitment to return a Result rather than an Option
- enforce the all-zeroes reserved value consensus rules
- change `PreSaplingReserved([u8; 32])` to `PreSaplingReserved`
- change `ChainHistoryActivationReserved([u8; 32])` to `ChainHistoryActivationReserved`
- update the function comments to describe when each variant is verified
* Fix comment whitespace
* Implement Expanded to Compact Difficulty
* Implement Arbitrary for CompactDifficulty
Remove the derive, and generate values from random block
hashes.
* Implement Arbitrary for ExpandedDifficulty and Work
* Use Arbitrary for CompactDifficulty in Arbitrary for Block
* Test difficulty on all block test vectors
And cleanup some duplicate test code
* Round-trip tests for compact test cases
* Round-trip tests for compact difficulty in block test vectors
* Make Add for Work return PartialCumulativeWork
Remove AddAssign for Work
Rewrite a proptest using Sub for PartialCumulativeWork
Use Arbitrary for Work
* Add roundtrip work sum tests
* Add roundtrip comparison difficulty tests
* Add failing proptest cases due to test bugs
* Use Some(_) rather than _.into()
* Reduce visibility of difficulty type inner values
* Split work and other difficulty proptests
This change makes sure that rejected work values don't disable property
tests on other types.
