Line interface Bitcoin programming is a very rich field now.
The Bitcoin Core client exposes various JSON RPC commands that can be used to construct raw transactions and perform other functions via custom scripts or programs.
A Complete Guide to Understanding This Blockchain Concept
Also, the command-line tool, Bitcoin-cli, is available, which makes use of the JSON-RPC interface and provides a rich toolset to work with Bitcoin.
These APIs are also available via many online service providers in the form of bitcoin APIs, and they provide a simple HTTP REST interface.
Bitcoin APIs, such as Blockchain.info ( ) and BitPay ( https://blockchain.info/api https:/ ), Block.io ( ), and many others, offer a myriad of options to develop Bitcoin-based /bitpay.com/api https://www.block.io solutions.
A list is shown as follows, and those of you interested can further explore the libraries.
Libbitcoin: Available at and provides powerful command-line utilities and clients https://libbitcoin.dyne.org/ Pycoin: Available at , is a library for Python https://github.com/richardkiss/pycoin Bitcoinj: This library is available at and is implemented in Java https://bitcoinj.github.io/ There are many online bitcoin APIs available; the most commonly used APIs are listed as follows: https://bitcore.io/ https://bitcoinjs.org/ https://blockchain.info/api As all APIs offer almost similar type of functionality, it can get confusing to decide which one to use.
It is also difficult to recommend which API is the best because all APIs are similarly feature-rich.
Why This Matters for Blockchain Technology
One thing to keep in mind, however, is, security, so whenever you evaluate an API for usage, in addition to assessing the offered features, also evaluate how secure is the design of the API.
