Functions

func NewBlobProofVerifier

func NewBlobProofVerifier(
	impl string,
	ts *gokzg4844.JSONTrustedSetup,
) (proof.BlobProofVerifier, error)

NewBlobProofVerifier creates a new BlobVerifier with the given implementation.

Types

type BlobVerifier

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

BlobProofVerifier is a verifier for blobs.

func NewBlobVerifier

func NewBlobVerifier(
	proofVerifier proof.BlobProofVerifier,
) *BlobVerifier

NewBlobVerifier creates a new BlobVerifier with the given proof verifier.

func (*BlobVerifier) VerifyKZGProofs

func (bv *BlobVerifier) VerifyKZGProofs(
	scs *types.BlobSidecars,
) error

VerifyKZGProofs verifies the sidecars.

type Store

type Store struct {
	*filedb.RangeDB
	// contains filtered or unexported fields
}

Store is the default implementation of the AvailabilityStore.

func NewStore

func NewStore(
	beaconCfg *params.BeaconChainConfig,
	db db.DB,
) *Store

NewStore creates a new instance of the AvailabilityStore.

func (*Store) IsDataAvailable

func (s *Store) IsDataAvailable(
	ctx context.Context,
	slot primitives.Slot,
	b beacontypes.ReadOnlyBeaconBlock,
) bool

IsDataAvailable ensures that all blobs referenced in the block are stored before it returns without an error.

func (*Store) Persist

func (s *Store) Persist(
	slot primitives.Slot,
	sidecars *types.BlobSidecars,
) error

Persist ensures the sidecar data remains accessible, utilizing parallel processing for efficiency.
