This is gonna be awesome!
Just to clarify that a bit further in the case of Roomy, our ‘own take’ is still an extension of the permissioned data spec you’ve sketched out.
All the others I’m aware of - except for contrail which we’re coordinating/co-ideating with - are wholly separate implementations of permissioned/private data, which to be clear is very good and necessary. (The end-goal is convergence, but first we need divergence to earnestly map out the full problems/solutions space, and there will likely also be a need for more solutions than one.)
