+# JSON-RPC Interface
+
+The headless daemon `bitcoind` has the JSON-RPC API enabled by default, the GUI
+`bitcoin-qt` has it disabled by default. This can be changed with the `-server`
+option. In the GUI it is possible to execute RPC methods in the Debug Console
+Dialog.
+
+## RPC consistency guarantees
+
+State that can be queried via RPCs is guaranteed to be at least up-to-date with
+the chain state immediately prior to the call's execution. However, the state
+returned by RPCs that reflect the mempool may not be up-to-date with the
+current mempool state.
+
+### Transaction Pool
+
+The mempool state returned via an RPC is consistent with itself and with the
+chain state at the time of the call. Thus, the mempool state only encompasses
+transactions that are considered mine-able by the node at the time of the RPC.
+
+The mempool state returned via an RPC reflects all effects of mempool and chain
+state related RPCs that returned prior to this call.
+
+### Wallet
+
+The wallet state returned via an RPC is consistent with itself and with the
+chain state at the time of the call.
+
+Wallet RPCs will return the latest chain state consistent with prior non-wallet
+RPCs. The effects of all blocks (and transactions in blocks) at the time of the
+call is reflected in the state of all wallet transactions. For example, if a
+block contains transactions that conflicted with mempool transactions, the
+wallet would reflect the removal of these mempool transactions in the state.
+
+However, the wallet may not be up-to-date with the current state of the mempool
+or the state of the mempool by an RPC that returned before this RPC. For
+example, a wallet transaction that was BIP-125-replaced in the mempool prior to
+this RPC may not yet be reflected as such in this RPC response.

It is not suitable for debugging a multi-threaded C++ program, not even for getting backtraces. Please install the package `gdb` and
use the versioned gdb command (e.g. `gdb7111`).
