- On the subject of jargon, you’re seeing all of it because we’ve opened up the design process here on the forum and are weighing different options against each other. When this is in production, we will have settled on a much smaller set of options and simplified the messaging to make it understandable.
- On the subject of top-n, top validators (and all other validators as well) are currently forced to run Replicated Security consumer chains. Top-n gives us the ability to transition these to Partial Set Security without changing their security properties too much.
This is definitely a key difference between PSS and Mesh. I personally think that there is somewhat of a benefit in the simplicity of PSS. Delegators choose a validator and let them handle decisions of risk/reward of validation, as they specialize in it. Consumer chains get validators signing up and get their full stake immediately. Validators get to leverage their knowledge of the space, and finally have something other than marketing and uptime vanity metrics to differentiate themselves.
Of course all this can also be implemented in terms of mesh security, with various frameworks around it, but that stuff is not currently done yet.
