Oh I’m out on the edge myself here 
I just learned about these other uses for parsec with Davids response earlier in this topic (~8 hours ago).
Mm, I was thinking that datachains would maybe be a more significant long term storage of information, and as such it would presumably be interesting also outside of the specific sections. After all sharding is the practice of splitting up for example data [that you later want to retrieve] - and so if datachains was a component of the sharding, I was imagining that the information in the datachains was something that we later wanted to retrieve in some way. (Especially when the saying goes that “we don’t have blockchain, but instead datachains”).
OK, but then if this is not the case, yet another fragment is lit up a bit for me here, about the usage of parsec and datachains in the sections, but it sure makes other questions pop up when trying to wrap my head around it all 
. (splitting off from parsec topic a bit) Like:
- Exactly what is the nature of the data that goes into datachains?
- What is the lifecycle of that data?
- What is the relation to parsec, generally and in specific examples?
(But maybe the designers can shed more light on it.)
The thing is,besides from also wanting to understand all this, I got an idea for how parsec could be used in a slightly different framework, and I am trying to figure out if it would be possible. Might be bonkers but if not then it would be quite cool.
