It's not all intuitive and obvious, and I recommend starting out with testnet until you're pretty sure about what you're doing, Note that you can also run bitcoind as a daemon (background process) but I prefer to just give the server a dedicated terminalĪnd can then switch to this terminal if I want to see some of the current server output. While also listening out for local RPC calls. Otherwise it will just get straight into the continuous process of connecting to other nodes in the bitcoin network and starting or maintaining synchronisation with the network blockchain,
BITCOIN CORE RPC INTERFACE PASSWORD
If you don't have an rpc username and password set up in your bitcoin configuration file (in ~/.bitcoin/nf by default on linux) then bitcoind will print a message about this and exit. This will start bitcoind as both a client (which connects to other nodes in the bitcoin network) and a local server (which you can connect to for RPC calls). We'll need to run bitcoind as a server, which I do with the following command: I'm going to assume you have the bitcoin reference client (bitcoind) installed and set upĪnd I'm not going to talk about issues such as 'bootstrapping' the client (to reduce initial block chain synchonisation times),Īs there should be plenty of other material available for these topics elsewhere on the web. Running the reference client as an RPC server Some lower level details such as raw transaction construction. Whilst still retaining the possibility to get down and dirty with Using the RPC interface means that you can take advantage of reference client codeįor things like network and peer connectivity, wallet management and signing, While the reference client has a great deal of test coverage,Īnd deals with some tricky details very robustly. Python has good support for byte sequences and large integers and seems to be quiteĪ good fit for bitcoin operations in general,
BITCOIN CORE RPC INTERFACE SOFTWARE
If you're interested in writing more involved software that works with bitcoin transactions or the bitcoin blockchain. Python can work well as a kind of (overpowered) scripting language for automatingĬomplicated tasks through the bitcoin reference client, but this is also a great way to get started out (which is something that turns out to be almost trivially easy to set up).

In this post I show you how to call into this from Python The reference bitcoin client includes a powerful API and RPC interface.
