In-process INode for applications
INode interface is Bytecoin's high-level API library that provides network node functionality. Its in-process implementation allows to launch an instance of Bytecoin daemon inside any C++ application. As an example, it allows Bytecoin Wallet to run a native network node. What's more, if you have a local Bytecoin daemon running, INode will connect to it rather than create a new in-app instance. This update marks the start of Bytecoin lightweight wallet development, a long-awaited feature in CryptoNote ecosystem.
I guess INode is something new. Could you explain in more detail? Where could I find it on the website? Actually, it would be pretty good to make a special blog for bytecoin where developers will comment on what is happening.
INode's description that you quote is pretty self-explanatory. INode is a high-level API interface that has been introduced back in Bytecoin v.0.8.11. Basically, it is a C++ library that is capable of everything the CryptoNote network node should do. It can be used for other applications to replace bytecoind daemon running in the background and have everything inside one app. You may read more about the methods on our wiki but keep in mind that whole API section is going to be updated with the next release:
