What is the main difference between using one of the bitcoin libraries to create a project and using bitcoin core json RPC API directly by connecting to your node for everything?
If the library has no full node support, which part exactly requires you to use a fullnode and which part can be done without full node?
https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)#Java The link mentioned for library doesn't work here but I found BitcoinJ and it mentioned that you don't need local copy of bitcoin core so how does everything happen without node?
