That is the only way. All blockstates are calculated on registration, so there is no way to save that to a single blockstate. If there are that many, you may need to rethink your approach. You could maybe store a chunk capability with a map of blockpos -> blockstate, but I'm not sure that would save you much (after all, that is what the world saves). And you'd have a much harder time sorting out the rendering.

So that's mandatory now... Ok, registering attributes using the enqueWork method works. Thank you for the help

Is this the optimal way? The blocks should be used as a normal/basic building block, so there may be hundreds or maybe even a thousands of them in a single chunk.

For sure it is possible to do this, and in fact it has already been done. However it is not really a simple thing to achieve, specially if you are new to modding..you may want to take a look at the MIneColonies mod, which implements npcs that literally do what you want, and start exploring the vanilla code that handles villager entities
