I aim that 2024 will finally be the year that we get rid of the Knapsack coin selection algorithm in the Bitcoin Core codebase. I assume that there will be a few good parties around the halvening. I’m hoping to see Silent Payments, Cluster Mempool, and Package Relay (hopefully including Package RBF) get released. I don’t have any big surprises up my sleeve.

None of the above will be the most important things, though. I would guess that regulation of Bitcoin will be a focus in the next couple years which very well could have a huge impact on the overall direction of the project.
