# 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/`](../wallet/) and [`src/qt/`](../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/`](../wallet/), or [`src/qt/`](../qt/) directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited [`src/interfaces/`](../interfaces/) classes.

The [`src/node/`](./) directory is a new directory introduced in
[#14978](https://github.com/bitcoin/bitcoin/pull/14978) and at the moment is
sparsely populated. Eventually more substantial files like
[`src/validation.cpp`](../validation.cpp) and
[`src/txmempool.cpp`](../txmempool.cpp) might be moved there.

Remove irrelevant link to GitHub
doc: Remove irrelevant link to GitHub

Summary:
The doc nicely explains why the directory exists and it is irrelevant when it was introduced. Even if it was relevant, it could be trivially found out via `git log ./src/node/ | tail` without visiting GitHub

This concludes backport of core#21575 [6/6]
