# this is experimental software, expect problems and use on your own risk!

It contains most of the official RPC API methods (https://github.com/ethereum/wiki/wiki/JSON-RPC).
The db_getXXX and db_setXXX methods are removed and will not be implemented.

Checkout: https://github.com/bas-vk/go-ethereum/tree/jsonrpc

Start the geth node with the `--ipcexp` flag. This will start the IPC endpoint with the new RPC implementation.

New is support for push notification by creating a subsription on a particular event.

Introduce a new type Api in the rpc package:

// Api describes the set of methods offered over the RPC interface
type Api struct {
  Namespace string     // namespace under which the rpc methods of Service are exposed
  Version string       // api version for DApp's
  Service interface{}  // receiver instance which holds the methods
  Public bool          // indication if the methods must be considered safe for public use
}

Are these necessary? They can be implemented fairly easy by a client that needs it. If so can we use uint for the index.
TransactionInBlock(ctx context.Context, blockHash common.Hash, index int) (*types.Transaction, error)
ReceiptInBlock(ctx context.Context, blockHash common.Hash, index int) (*types.Receipt, error)


BalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)
PendingBalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)

Instead of adding a special method for pending can't we just use the block number to specify pending?
Currently we have -1 and -2 to indicate the pending and latest block in the RPC interface.
