Package executor

This package deals with state management for P-Chain blocks.

*Block

The *Block type implements the linear.Block interface. This is the type that the platformvm deals with when it uses linear.Blocks. *Block wraps a blocks.Block and a manager. The *Block itself doesn't have any state. The state is all held by the manager, and the *Block acts upon the manager to get/set the state. Therefore, we don't need to worry about deduplicating *Block instances.

The platformvm uses the manager to create blocks and query block state because the manager.GetBlock returns a stateful block (*Block), whereas state.State's GetStatelessBlock returns a blocks.Block.

Visitors

This package contains three implementations of blocks.Visitor: verifier, acceptor and rejector. These implement the logic for verifying, accepting and rejecting blocks. Each implementation has a reference to a shared *backend, which maintains state, etc. (The manager has a reference to the shared *backend as well.)

Functions

func VerifyWarpMessages 

func VerifyWarpMessages(
	ctx context.Context,
	networkID uint32,
	validatorState validators.State,
	pChainHeight uint64,
	b block.Block,
) error

VerifyWarpMessages verifies all warp messages in the block. If any of the warp messages are invalid, an error is returned.

When GPU acceleration is available and the block contains multiple BLS warp signatures, verification is batched through the GPU for throughput. Otherwise falls back to sequential CPU verification.

Types

type Block 

type Block struct {
	platformblock.Block
	// contains filtered or unexported fields
}

Exported for testing in platformvm package.

func (*Block) Accept 

func (b *Block) Accept(context.Context) error

func (*Block) EpochBit added in v1.11.14 

func (b *Block) EpochBit() bool

EpochBit implements the chain.Block interface Returns the epoch fence bit for FPC

func (*Block) FPCVotes added in v1.11.14 

func (b *Block) FPCVotes() [][]byte

FPCVotes implements the chain.Block interface Returns embedded fast-path consensus vote references

func (*Block) Options 

func (b *Block) Options(context.Context) ([2]chain.Block, error)

func (*Block) ParentID added in v1.16.56 

func (b *Block) ParentID() ids.ID

ParentID implements chain.Block interface by delegating to Parent()

func (*Block) Reject 

func (b *Block) Reject(context.Context) error

func (*Block) ShouldVerifyWithRuntime added in v1.22.87 

func (*Block) ShouldVerifyWithRuntime(context.Context) (bool, error)

func (*Block) Status added in v1.1.11 

func (b *Block) Status() uint8

Status implements chain.Block interface. Block status is tracked by the block state manager; this returns the default (processing) status since blocks reaching this code path have not yet been accepted or rejected.

func (*Block) Timestamp 

func (b *Block) Timestamp() time.Time

func (*Block) Verify 

func (b *Block) Verify(ctx context.Context) error

func (*Block) VerifyWithRuntime added in v1.22.87 

func (b *Block) VerifyWithRuntime(ctx context.Context, blockContext *runtime.Runtime) error

type Manager 

type Manager interface {
	state.Versions

	// Returns the ID of the most recently accepted chain.
	LastAccepted() ids.ID

	SetPreference(blkID ids.ID)
	Preferred() ids.ID

	GetBlock(blkID ids.ID) (chain.Block, error)
	GetStatelessBlock(blkID ids.ID) (platformblock.Block, error)
	NewBlock(platformblock.Block) chain.Block

	// VerifyTx verifies that the transaction can be issued based on the currently
	// preferred state. This should *not* be used to verify transactions in a chain.
	VerifyTx(tx *txs.Tx) error

	// VerifyUniqueInputs verifies that the inputs are not duplicated in the
	// provided blk or any of its ancestors pinned in memory.
	VerifyUniqueInputs(blkID ids.ID, inputs set.Set[ids.ID]) error
}

func NewManager 

func NewManager(
	mempool mempool.Mempool[*txs.Tx],
	metrics metrics.Metrics,
	s state.State,
	txExecutorBackend *executor.Backend,
	validatorManager validators.Manager,
