# 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.
