Types

type Client 

type Client struct {
	service.BaseService
	// contains filtered or unexported fields
}

Client is an RPC client, which uses light#Client to verify data (if it can be proved). Note, merkle.DefaultProofRuntime is used to verify values returned by ABCI#Query.

func NewClient 

func NewClient(next rpcclient.Client, lc LightClient, opts ...Option) *Client

NewClient returns a new client.

func (*Client) ABCIInfo 

func (c *Client) ABCIInfo(ctx context.Context) (*coretypes.ResultABCIInfo, error)

func (*Client) ABCIQuery 

func (c *Client) ABCIQuery(ctx context.Context, path string, data tmbytes.HexBytes) (*coretypes.ResultABCIQuery, error)

ABCIQuery requests proof by default.

func (*Client) ABCIQueryWithOptions 

func (c *Client) ABCIQueryWithOptions(ctx context.Context, path string, data tmbytes.HexBytes,
	opts rpcclient.ABCIQueryOptions) (*coretypes.ResultABCIQuery, error)

ABCIQueryWithOptions returns an error if opts.Prove is false. ABCIQueryWithOptions returns the result for the given height (opts.Height). If no height is provided, the results of the block preceding the latest are returned.

func (*Client) Block 

func (c *Client) Block(ctx context.Context, height *int64) (*coretypes.ResultBlock, error)

Block calls rpcclient#Block and then verifies the result.

func (*Client) BlockByHash 

func (c *Client) BlockByHash(ctx context.Context, hash tmbytes.HexBytes) (*coretypes.ResultBlock, error)

BlockByHash calls rpcclient#BlockByHash and then verifies the result.

func (*Client) BlockResults 

func (c *Client) BlockResults(ctx context.Context, height *int64) (*coretypes.ResultBlockResults, error)

BlockResults returns the block results for the given height. If no height is provided, the results of the block preceding the latest are returned.

func (*Client) BlockSearch 

func (c *Client) BlockSearch(
	ctx context.Context,
	query string,
	page, perPage *int,
	orderBy string,
) (*coretypes.ResultBlockSearch, error)

func (*Client) BlockchainInfo 

func (c *Client) BlockchainInfo(ctx context.Context, minHeight, maxHeight int64) (*coretypes.ResultBlockchainInfo, error)

BlockchainInfo calls rpcclient#BlockchainInfo and then verifies every header returned.

func (*Client) BroadcastEvidence 

func (c *Client) BroadcastEvidence(ctx context.Context, ev types.Evidence) (*coretypes.ResultBroadcastEvidence, error)

func (*Client) BroadcastTxAsync 

func (c *Client) BroadcastTxAsync(ctx context.Context, tx types.Tx) (*coretypes.ResultBroadcastTx, error)

func (*Client) BroadcastTxCommit 

func (c *Client) BroadcastTxCommit(ctx context.Context, tx types.Tx) (*coretypes.ResultBroadcastTxCommit, error)

func (*Client) BroadcastTxSync 

func (c *Client) BroadcastTxSync(ctx context.Context, tx types.Tx) (*coretypes.ResultBroadcastTx, error)

func (*Client) CheckTx 

func (c *Client) CheckTx(ctx context.Context, tx types.Tx) (*coretypes.ResultCheckTx, error)

func (*Client) Commit 

func (c *Client) Commit(ctx context.Context, height *int64) (*coretypes.ResultCommit, error)

func (*Client) ConsensusParams 

func (c *Client) ConsensusParams(ctx context.Context, height *int64) (*coretypes.ResultConsensusParams, error)

func (*Client) ConsensusState 

func (c *Client) ConsensusState(ctx context.Context) (*coretypes.ResultConsensusState, error)

func (*Client) DumpConsensusState 

func (c *Client) DumpConsensusState(ctx context.Context) (*coretypes.ResultDumpConsensusState, error)

func (*Client) Genesis 

func (c *Client) Genesis(ctx context.Context) (*coretypes.ResultGenesis, error)

func (*Client) GenesisChunked 

func (c *Client) GenesisChunked(ctx context.Context, id uint) (*coretypes.ResultGenesisChunk, error)

func (*Client) Header 

func (c *Client) Header(ctx context.Context, height *int64) (*coretypes.ResultHeader, error)

Header fetches and verifies the header directly via the light client

func (*Client) HeaderByHash 

func (c *Client) HeaderByHash(ctx context.Context, hash tmbytes.HexBytes) (*coretypes.ResultHeader, error)

HeaderByHash calls rpcclient#HeaderByHash and updates the client if it's falling behind.

func (*Client) Health 

func (c *Client) Health(ctx context.Context) (*coretypes.ResultHealth, error)

func (*Client) NetInfo 

func (c *Client) NetInfo(ctx context.Context) (*coretypes.ResultNetInfo, error)

func (*Client) NumUnconfirmedTxs 

func (c *Client) NumUnconfirmedTxs(ctx context.Context) (*coretypes.ResultUnconfirmedTxs, error)

func (*Client) OnStart 

func (c *Client) OnStart() error

func (*Client) OnStop 

func (c *Client) OnStop()

func (*Client) RegisterOpDecoder 

func (c *Client) RegisterOpDecoder(typ string, dec merkle.OpDecoder)

func (*Client) RemoveTx 

func (c *Client) RemoveTx(ctx context.Context, txKey types.TxKey) error

func (*Client) Status 

func (c *Client) Status(ctx context.Context) (*coretypes.ResultStatus, error)

func (*Client) Subscribe 

func (c *Client) Subscribe(ctx context.Context, subscriber, query string,
	outCapacity ...int) (out <-chan coretypes.ResultEvent, err error)

func (*Client) SubscribeWS 

func (c *Client) SubscribeWS(ctx *rpctypes.Context, query string) (*coretypes.ResultSubscribe, error)

SubscribeWS subscribes for events using the given query and remote address as a subscriber, but does not verify responses (UNSAFE)! TODO: verify data

func (*Client) Tx 

func (c *Client) Tx(ctx context.Context, hash tmbytes.HexBytes, prove bool) (*coretypes.ResultTx, error)

Tx calls rpcclient#Tx method and then verifies the proof if such was requested.

) (*coretypes.ResultValidators, error)

Validators fetches and verifies validators.

type KeyPathFunc 

type KeyPathFunc func(path string, key []byte) (merkle.KeyPath, error)

KeyPathFunc builds a merkle path out of the given path and key.

func DefaultMerkleKeyPathFn 

func DefaultMerkleKeyPathFn() KeyPathFunc

DefaultMerkleKeyPathFn creates a function used to generate merkle key paths from a path string and a key. This is the default used by the cosmos SDK. This merkle key paths are required when verifying /abci_query calls

type LightClient 

type LightClient interface {
	ChainID() string
	Update(ctx context.Context, now time.Time) (*types.LightBlock, error)
	VerifyLightBlockAtHeight(ctx context.Context, height int64, now time.Time) (*types.LightBlock, error)
