Functions

func CrpytoCtx

func CrpytoCtx() gokzg4844.Context

CryptoCtx returns a context object stores all of the necessary configurations to allow one to create and verify blob proofs. This function is expensive to run if the crypto context isn't initialized, so it is recommended to pre-initialize by calling InitializeCryptoCtx

func InitializeCrypytoCtx

func InitializeCrypytoCtx()

InitializeCrypytoCtx initializes the global context object returned via CryptoCtx

func PointEvaluationPrecompile

func PointEvaluationPrecompile(input []byte) ([]byte, error)

PointEvaluationPrecompile implements point_evaluation_precompile from EIP-4844

Types

}

type Root

type Root [32]byte

type Slot

type Slot uint64

type VersionedHash
