Types ¶
type API ¶
type API struct {
// contains filtered or unexported fields
}
API introduces chain specific functionality to the evm
func (*API) GetBlockAggregateSignature ¶
func (a *API) GetBlockAggregateSignature(ctx context.Context, blockID ids.ID, quorumNum uint64, chainIDStr string) (signedMessageBytes hexutil.Bytes, err error)
GetBlockAggregateSignature fetches the aggregate signature for the requested [blockID]
func (*API) GetBlockSignature ¶
GetBlockSignature returns the BLS signature associated with a blockID.
func (*API) GetMessage ¶
GetMessage returns the Warp message associated with a messageID.
type Backend ¶
type Backend interface {
// AddMessage signs [core] and adds it to the warp backend database.
AddMessage(msg *warp.Message) error
// GetMessageSignature validates the message and returns the signature of the requested message.
GetMessageSignature(ctx context.Context, msg *warp.Message) ([]byte, error)
// GetBlockSignature returns the signature of a hash payload containing blockID if it's the ID of an accepted block.
GetBlockSignature(ctx context.Context, blockID ids.ID) ([]byte, error)
// GetMessage retrieves the [core] from the warp backend database if available.
GetMessage(messageHash ids.ID) (*warp.Message, error)
// Verify verifies the signature of the message.
Verify(ctx context.Context, msg *warp.Message, _ []byte) error
}
Backend tracks signature-eligible warp messages and provides an interface to fetch them. The backend is also used to query for warp message signatures by the signature request handler.
Post-ZAP the signed subject is the warp.Message (its D = ID() is what the BLS Beam signs via warp.BeamSigningBytes(D)); the deleted RLP unsigned-message type is gone.
func NewBackend ¶
func NewBackend( networkID uint32, sourceChainID ids.ID, warpSigner warp.Signer, blockClient BlockClient, validatorReader interfaces.ValidatorReader, db database.Database, signatureCache cache.Cacher[ids.ID, []byte], offchainMessages [][]byte, ) (Backend, error)
NewBackend creates a new Backend, and initializes the signature cache and message tracking database.
type BlockClient ¶
type Client ¶
type Client interface {
GetMessage(ctx context.Context, messageID ids.ID) ([]byte, error)
GetMessageSignature(ctx context.Context, messageID ids.ID) ([]byte, error)
GetMessageAggregateSignature(ctx context.Context, messageID ids.ID, quorumNum uint64, chainIDStr string) ([]byte, error)
GetBlockSignature(ctx context.Context, blockID ids.ID) ([]byte, error)
GetBlockAggregateSignature(ctx context.Context, blockID ids.ID, quorumNum uint64, chainIDStr string) ([]byte, error)
}
