Types ¶

type Client ¶

type Client struct {
	EthOracle *EthLightChainOracle
}

func NewAppchainClient ¶

func NewAppchainClient(ropsten string, path string, logger logrus.FieldLogger) (*Client, error)

type EthLightChainOracle ¶

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

func NewRinkebyOracle ¶

func NewRinkebyOracle(storagePath string, logger logrus.FieldLogger) (*EthLightChainOracle, error)

TODO: need to start with special header height

func NewRopstenOracle ¶

func NewRopstenOracle(ropstenPath string, storagePath string, readOnly bool, logger logrus.FieldLogger) (*EthLightChainOracle, error)

NewRopstenOracle inits with ropsten block 10105112, receives above the 10105112 headers

func (*EthLightChainOracle) CurrentHeader ¶

func (oracle *EthLightChainOracle) CurrentHeader() *types.Header

CurrentHeader retrieves the current head header of the canonical chain.

func (*EthLightChainOracle) GetHeader ¶

func (oracle *EthLightChainOracle) GetHeader(hash common.Hash) *types.Header

GetHeader retrieves a block header by hash

func (*EthLightChainOracle) InsertBlockHeaders ¶

func (oracle *EthLightChainOracle) InsertBlockHeaders(headers []*types.Header) (int, error)

InsertBlockHeaders attempts to insert the given header chain in to the local chain, possibly creating a reorg. If an error is returned, it will return the index number of the failing header as well an error describing what went wrong. Ropsten receives the block header after the height of 10105112

func (*EthLightChainOracle) VerifyProof ¶

func (oracle *EthLightChainOracle) VerifyProof(receipt *types.Receipt, proof []byte) error
