Functions

func BuildAlphabetPreimage

func BuildAlphabetPreimage(traceIndex *big.Int, claim *big.Int) []byte

BuildAlphabetPreimage constructs the claim bytes for the index and claim.

Types

type AlphabetTraceProvider

type AlphabetTraceProvider struct {
	// contains filtered or unexported fields
}

AlphabetTraceProvider is a [TraceProvider] that monotonically increments the starting l2 block number as the claim value.

func NewTraceProvider

func NewTraceProvider(startingBlockNumber *big.Int, depth types.Depth) *AlphabetTraceProvider

NewTraceProvider returns a new [AlphabetProvider].

func (*AlphabetTraceProvider) AbsolutePreStateCommitment

func (ap *AlphabetTraceProvider) AbsolutePreStateCommitment(_ context.Context) (common.Hash, error)

func (*AlphabetTraceProvider) Get

func (ap *AlphabetTraceProvider) Get(ctx context.Context, i types.Position) (common.Hash, error)

Get returns the claim value at the given index in the trace.

func (*AlphabetTraceProvider) GetL2BlockNumberChallenge

func (ap *AlphabetTraceProvider) GetL2BlockNumberChallenge(_ context.Context) (*types.InvalidL2BlockNumberChallenge, error)

func (*AlphabetTraceProvider) GetStepData

func (ap *AlphabetTraceProvider) GetStepData(ctx context.Context, pos types.Position) ([]byte, []byte, *types.PreimageOracleData, error)
