## Backbone Roadmap

The focus of the project in terms of development for the year to come is to
have the main subsystems basically functional (tx-relay, addr-relay, topo-mngr,
block-relay), including the low-level connectivity code with the consensus engine.

This development roadmap should encompass the year 2026 and a bit beyond.
.
The roadmap is provided on an indicative title only and as a "forward-looking" statement.

### Functionalities

High priorities:
- IBD / blocks processing / blocks servicing

Middle priorities:

- new mempool design and implementation
- cap'n proto servers interfaces

Low priorities:
- intra-process encryption
