Add a submitBlock method to the Mining IPC interface, similar to the submitblock RPC. This accepts a fully assembled block, validates it, and if accepted as new, processes it into chainstate. This is needed for Stratum v2 Job Declarator Server (JDS), where accepted solutions may correspond to jobs not tied to a Bitcoin Core BlockTemplate. JDS receives PushSolution fields and reconstructs full blocks; without an IPC submitBlock method, final submission requires the submitblock RPC. The method returns detailed status (reason/debug strings) matching the checkBlock pattern, giving callers enough information to handle validation failures.
src/node/
The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
