func RegisterQueryHandler 

func RegisterQueryHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterQueryHandler registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterQueryHandlerClient 

func RegisterQueryHandlerClient(ctx context.Context, mux *runtime.ServeMux, client QueryClient) error

RegisterQueryHandlerClient registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "QueryClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "QueryClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "QueryClient" to call the correct interceptors.

func RegisterQueryHandlerFromEndpoint 

func RegisterQueryHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterQueryHandlerFromEndpoint is same as RegisterQueryHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterQueryHandlerServer 

func RegisterQueryHandlerServer(ctx context.Context, mux *runtime.ServeMux, server QueryServer) error

RegisterQueryHandlerServer registers the http handlers for service Query to "mux". UnaryRPC :call QueryServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features to stop working. Consider using RegisterQueryHandlerFromEndpoint instead.

func RegisterQueryServer 

func RegisterQueryServer(s grpc1.Server, srv QueryServer)

Consider we have a Merkle tree with following structure: 

          ROOT
         /    \
    H1234      H5555
   /     \       \
 H12     H34      H55
/  \    /  \     /

H1 H2 H3 H4 H5 L1 L2 L3 L4 L5 To prove L3 was part of ROOT we need: - btc_transaction_index = 2 which in binary is 010 (where 0 means going left, 1 means going right in the tree) - merkle_nodes we'd have H4 || H12 || H5555 By looking at 010 we would know that H4 is a right sibling, H12 is left, H5555 is right again.

type SubmissionKey 

type SubmissionKey struct {
	Key []*TransactionKey `protobuf:"bytes,1,rep,name=key,proto3" json:"key,omitempty"`
}

Checkpoint can be composed from multiple transactions, so to identify whole submission we need list of transaction keys. Each submission can generally be identified by this list of (txIdx, blockHash) tuples. Note: this could possibly be optimized as if transactions were in one block they would have the same block hash and different indexes, but each blockhash is only 33 (1 byte for prefix encoding and 32 byte hash), so there should be other strong arguments for this optimization
