The Bitcoin-tui is a small terminal UI for a Bitcoin node, written in C++, based on the FTXUI framework. There was a small (limited) demo of the current capabilities of the tui, that showed the dashboard, the mempool explorer (including recent blocks), peers dashboard and the tools tab which also contains a tool to broadcast a (raw) transaction.

There where some question if the transaction visualizations where already on the level of mempool.space (with all the arrows) and if this could be achieved with a TUI. Currently the visualization of the transaction is somewhat limited but it should be possible to create the same style in the TUI, given that FTXUI supports a Canvas object. But could limited to terminal support.

In the yet to be released version there is support for Lua scripting "tabs", users can write custom tabs for their own ideas and visualizations. One of these Lua Tabs is a view only wallet function, which was demoed and the new QR code visual was also shown. Lua is also very suitable for users who use LLM's to create their own visualizations.

There was a short discussion of the direction of the project, where was indicated that the current C++ tabs will be re-written to LUA versions. The UI elements will be made available to the LUA scripting side via build in Components.

The interaction with the node is currently via RPC, which also give the ability to use bitcoin cores ability of allowlisting RPC commands. On the question if there where plans to extend the connectivity to IPC, there is no objection to that but also no direct plans.

The next release of the TUI will be soon, the wait is also for the next release of FTXUI. FTXUI has indicated to work towards a new release soon, which is better documented and has increased stability.
