Expand description

A contextually verified block, ready to be committed directly to the finalized state with no checks, if it becomes the root of the best non-finalized chain.

Used by the state service and non-finalized Chain.

Note: The difference between a CheckpointVerifiedBlock and a ContextuallyVerifiedBlock is that the CheckpointVerifier doesn’t bind the transaction authorizing data to the ChainHistoryBlockTxAuthCommitmentHash, but the NonFinalizedState and FinalizedState do.

Fields§

§block: Arc<Block>

The block to commit to the state.

§hash: Hash

The hash of the block.

§height: Height

The height of the block.

§new_outputs: HashMap<OutPoint, OrderedUtxo>

New transparent outputs created in this block, indexed by OutPoint.

Note: although these transparent outputs are newly created, they may not be unspent, since a later transaction in a block can spend outputs of an earlier transaction.

This field can also contain unrelated outputs, which are ignored.

§spent_outputs: HashMap<OutPoint, OrderedUtxo>

The outputs spent by this block, indexed by the transparent::Input’s OutPoint.

Note: these inputs can come from earlier transactions in this block, or earlier blocks in the chain.

This field can also contain unrelated outputs, which are ignored.

§transaction_hashes: Arc<[Hash]>

A precomputed list of the hashes of the transactions in this block, in the same order as block.transactions.

§chain_value_pool_change: ValueBalance<NegativeAllowed>

The sum of the chain value pool changes of all transactions in this block.

Implementations§

source§

impl ContextuallyVerifiedBlock

source

pub fn test_with_zero_spent_utxos( block: impl Into<SemanticallyVerifiedBlock>, ) -> Self

Create a block that’s ready for non-finalized Chain contextual validation, using a SemanticallyVerifiedBlock and fake zero-valued spent UTXOs.

Only for use in tests.

source

pub fn test_with_chain_pool_change( block: impl Into<SemanticallyVerifiedBlock>, fake_chain_value_pool_change: ValueBalance<NegativeAllowed>, ) -> Self

Create a ContextuallyVerifiedBlock from a Block or SemanticallyVerifiedBlock, using a fake chain value pool change.

Only for use in tests.

source

pub fn test_with_zero_chain_pool_change( block: impl Into<SemanticallyVerifiedBlock>, ) -> Self

Create a ContextuallyVerifiedBlock from a Block or SemanticallyVerifiedBlock, with no chain value pool change.

Only for use in tests.

source§

impl ContextuallyVerifiedBlock

source

pub fn with_block_and_spent_utxos( semantically_verified: SemanticallyVerifiedBlock, spent_outputs: HashMap<OutPoint, OrderedUtxo>, ) -> Result<Self, ValueBalanceError>

Create a block that’s ready for non-finalized Chain contextual validation, using a SemanticallyVerifiedBlock and the UTXOs it spends.

When combined, semantically_verified.new_outputs and spent_utxos must contain the Utxos spent by every transparent input in this block, including UTXOs created by earlier transactions in this block.

Note: a ContextuallyVerifiedBlock isn’t actually contextually valid until Chain::push() returns success.
