Functions ¶
func GenerateExecutionReceipt ¶ added in v0.30.0
func SPOCKProve ¶ added in v0.29.0
func SPOCKProve( sk crypto.PrivateKey, data []byte, kmac hash.Hasher, ) ( crypto.Signature, error, )
This is a temporary wrapper that simulates a call to SPoCK prove, required for the emulator build. The function is never called by the emulator although it is required for a successful build.
TODO(tarak): remove once the crypto module properly implements a non-relic version of SPOCKProve.
Types ¶
type BlockComputer ¶
type BlockComputer interface {
ExecuteBlock(
ctx context.Context,
parentBlockExecutionResultID flow.Identifier,
block *entity.ExecutableBlock,
snapshot snapshot.StorageSnapshot,
derivedBlockData *derived.DerivedBlockData,
) (
*execution.ComputationResult,
error,
)
}
A BlockComputer executes the transactions in a block.
func NewBlockComputer ¶
func NewBlockComputer( vm fvm.VM, vmCtx fvm.Context, metrics module.ExecutionMetrics, tracer module.Tracer, logger zerolog.Logger, committer ViewCommitter, signer module.Local, executionDataProvider *provider.Provider, colResCons []result.ExecutedCollectionConsumer, ) (BlockComputer, error)
NewBlockComputer creates a new block executor.
type ViewCommitter ¶ added in v0.16.0
type ViewCommitter interface {
// CommitView commits an execution snapshot and collects proofs
CommitView(
*snapshot.ExecutionSnapshot,
flow.StateCommitment,
) (
flow.StateCommitment,
[]byte,
*ledger.TrieUpdate,
error,
)
}
ViewCommitter commits execution snapshot to the ledger and collects the proofs
