I see in go-ethereum/consensus/ethash/api.go there is a GetWork API, but I'm trying to figure out how to use it. Can someone provide a quick example in golang? I have been able to successfully receive GetWork data in my go application by doing an http post to the localhost http geth interface, but I'd rather get the information via API if possible.

How to watch for a transaction on a specific Ethereum address using Web3 and pubsub JSON RPC module
As the title says, I'd like to know how can I monitor an Ethereum address for received transactions using Web3js and the JSON RPC pubsub module. I know I can subscribe to get all pending transactions and check them all one by one, but that seems awfully inefficient. I've seen I can monitor logs for a given address, but that doesn't seem to be an option since a standard Ethereum transaction (i.e. send 0.1 ETH from A to B) does not generate any logs (and please correct me if I'm wrong) and only contract calls can. So... do you know how I could do this in the most efficient way?

DEPRECATED! Java implementation of the Ethereum yellowpaper. For JSON-RPC and other client features check Ethereum Harmony - Ethereum-eternity/ethereumj The JSON-RPC format expects eth_call to have a specific data field format that requires normalizing the contract function balanceOf to a short Function Selector. To do this, we take out the names and the type of inputs it takes, and take that as a string. We then run it through Ethereum’s sha3 keccak hash: JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs. JSON-RPC is a stateless, light-weight remote procedure call (RPC) protocol. Primarily this specification defines several data structures and the rules around their processing. trace_callMany. Performs multiple call traces on top of the same block. i.e. transaction n will be executed on top of a pending block with all n-1 transactions applied (traced) first. Allows to trace dependent transactions. Parameters. Array - List of trace calls with the type of trace, one or more of: "vmTrace", "trace", "stateDiff".; Quantity or Tag - (optional) integer block number, or the ... Ethereum JSON-RPC APIs use a name-space system. RPC methods are grouped into several categories depending on their purpose. All method names are composed of the namespace, an underscore, and the actual method name within the namespace. For example, the eth_call method resides in the eth namespace. Access to RPC methods can be enabled on a per ...
