Cached off-chain groups

[vplasencia]

Description

Cached groups is a feature for really big groups that will need to generate merkle proofs, Bandada would help with that. It's not necessary for general groups (most groups).

It has the disadvantage that there are a lot of IMTs cached every time the server is restarted.

If this is removed, the infrastructure won't have that feature and will be faster and if it's not removed, the infrastructure may be slower.

Solution

Some ideas from @AtHeartEngineer

• Maybe this feature should be turned on/off based on group size.

• Make some imaginary threshold, lets say 2^10 entries gets caching turned on, and everything below that doesn't.
