Infura supports JSON-RPC over both HTTPS & WebSocket interfaces. In this tutorial, we’ll go through why you’d use each interface, as well as how to access the #Ethereum API via both methods using a Node.js example

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.
Parity Technologies on Twitter: "UPDATE: The scope of the fixed vulnerability is wider than originally thought. *Everyone* who runs Parity Ethereum, not just those who serve JSON-RPC publicly, should update to 2.2.10-stable and 2.3.3-beta as soon as 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?

What is JSON/RPC in Ethereum? It is a native communication protocol for interacting with the ethereum node. JSON/RPC contains a suite of low-level commands that can be sent to a node, over HTTPS or WebSockets. 外部からGethにアクセスするために必要なJSON RPCについて書いていきます。 Category About Ethereum(Geth)でJSON RPCを使って外部からアクセスする Geth. 公開: 2018-01-28. 更新: 2020-04-29. こんにちは、いつもお読みいただきありがとうございます。 ... Currently cpp-ethereum,go-ethereum, and parity provide JSON-RPC communication over http and IPC (unix socket Linux and OSX/named pipes on Windows). Version 1.4 of go-ethereum, version 1.6 of Parity and version 1.3 of Hyperledger Besu onwards have websocket support. ¶ The default block parameter 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: DEPRECATED!
