Bitcoin core rpc interface11/13/2022 ![]() Although Bitcoin Core's RPC interface does use authentication, it does not use encryption, so your login credentials are sent as clear text that can be read by anyone on your network path. Do not enable RPC connections over the public Internet. using a VPN or port forwarding with SSH or stunnel). These settings are only meant for enabling connections over secure private networks or connections that have been otherwise secured (e.g. Securing remote network access: You may optionally allow other computers to remotely control Bitcoin Core by setting the rpcallowip and rpcbind configuration parameters. For this reason, it is important to only use Bitcoin Core for security-sensitive operations on a computer whose other programs you trust. Additionally, other programs on your computer can attempt to provide an RPC interface on the same port as used by Bitcoin Core in order to trick you into revealing your authentication credentials. Any program on your computer with access to the file system and local network can obtain this level of access. Securing local network access: By default, the RPC interface can only be accessed by a client running on the same computer and only after the client provides a valid authentication credential (username and passphrase). For this reason, you should not use Bitcoin Core for security sensitive operations on systems you do not exclusively control, such as shared computers or virtual private servers. This includes being able to record any passphrases you enter for unlocking your encrypted wallets or changing settings so that your Bitcoin Core program tells you that certain transactions have multiple confirmations even when they aren't part of the best block chain. Securing the executable: Anyone with physical or remote access to the computer, container, or virtual machine running Bitcoin Core can compromise either the whole program or just the RPC interface. This section suggests how you should use and configure Bitcoin Core to reduce the risk that its RPC interface will be abused. The RPC interface allows other programs to control Bitcoin Core, including the ability to spend funds from your wallets, affect consensus verification, read private data, and otherwise perform operations that can cause loss of money, data, or privacy. #Bitcoin core rpc interface how to#The release notes of a new major release come with detailed instructions on what RPC features were deprecated and how to re-enable them temporarily. Usually deprecated features can be re-enabled during the grace-period of one major version via the -deprecatedrpc= command line option. The version tuple can be retrieved by e.g. This makes the RPC interface implicitly versioned on the major version. The RPC interface might change from one major version of Bitcoin Core to the next. In the GUI it is possible to execute RPC methods in the Debug Console Dialog. This can be changed with the -server option. The headless daemon bitcoind has the JSON-RPC API enabled by default, the GUI bitcoin-qt has it disabled by default. ![]()
