This introduces compliance issues with more strict clients. There are the major misbehaviors that I found: - returning non-200 HTTP codes for RPC errors like "Method not found" (this is not a server error or an HTTP error) - returning both `"error"` and `"result"` fields together in a response object. - different error-handling behavior for single and batched RPC requests (batches contain errors in the response but single requests will actually throw HTTP errors) https://github.com/bitcoin/bitcoin/pull/15495 added regression tests after a discussion in https://github.com/bitcoin/bitcoin/pull/15381 to kinda lock in our RPC behavior to preserve backwards compatibility. https://github.com/bitcoin/bitcoin/pull/12435 was an attempt to allow strict 2.0 compliance behind a flag, but was abandoned. The approach in this PR is not strict and preserves backwards compatibility in a familiar bitcoin-y way: all old behavior is preserved, but new rules are applied to clients that opt in. One of the rules in the [JSON RPC 2.0 spec](https://www.jsonrpc.org/specification#request_object) is that the kv pair `"jsonrpc": "2.0"` must be present in the request. Well, let's just use that to trigger strict 2.0 behavior! When that kv pair is included in a request object, the [response will adhere to strict JSON-RPC 2.0 rules](https://www.jsonrpc.org/specification#response_object), essentially: - always return HTTP 200 "OK" unless there really is a server error or malformed request - either return `"error"` OR `"result"` but never both - same behavior for single and batch requests If this is merged next steps can be: - Refactor bitcoin-cli to always use strict 2.0 - Refactor the python test framework to always use strict 2.0 for everything - Begin deprecation process for 1.0/1.1 behavior (?) If we can one day remove the old 1.0/1.1 behavior we can clean up the rpc code quite a bit.

Just suggested changes since the last review: changing uncaught exception error code from PARSE_ERROR to MISC_ERROR, renaming a few things, and adding comments. tdb3: re ACK for cbc6c440e3811d342fa570713702900b3e3e75b9 Tree-SHA512: 0b702ed32368b34b29ad570d090951a7aeb56e3b0f2baf745bd32fdc58ef68fee6b0b8fad901f1ca42573ed714b150303829cddad4a34ca7ad847350feeedb36
Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt
(GUI) orbin/bitcoind
(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
