- to create a custom libcc.so:
- 
- 1. change "func0" and "func1" to method names that fit your custom cc. Of course, you can create more functions by adding another entry to RPC_FUNCS. there is not any practical limit to the number of methods.
- 
- 2. For each method make sure there is a UniValue function declaration and CUSTOM_DISPATCH has an if statement checking for it that calls the custom_func
- 
- 3. write the actual custom_func0, custom_func1 and custom_validate in customcc.cpp
- 
- 4. ./makecustom, which builds cclib.cpp with -DBUILD_CUSTOMCC and puts the libcc.so in ~/hush3/src and rebuilds hushd
- 
- 5. launch your chain with -ac_cclib=customcc -ac_cc=2
