Functions

func CheckBlockHash

func CheckBlockHash(ctx context.Context, stateBlock *state.Block, L1Client L1Requester, checkerName string) error

CheckBlockHash is a method that checks the L1 block hash

Types

type AsyncCheck

type AsyncCheck struct {

	// Wg is a wait group to wait for the result
	Wg sync.WaitGroup
	// contains filtered or unexported fields
}
