Updating a kernel requires the chain to be stopped, or it used to at least, building an app to handle some of the same functionality with smart contracts creates a poduct on the hub where there is a fully operational ecosystem that can be enguaed internationally - and updates to the core fucntionality are non-consequential.
That’s the logic, anyhow. The management of services that generate net positvie cash flow, being bootstrapped by the community pool - is an idea I’ve thought is worth serious consideration. The goal is for those funds to feed back into the ecosystem, perhaps - enguage new participants in the ecosystem by introducing and/or encouraging the “buillt in” payment rail for those services, and having branded laborer’s servicing those job funcitons.
Something else to consider - if a validator can multi-task, manage a small team performing some service, and he makes addional income from this service, they might be less likely to dump the tokens - AND there would be that additonal network value introducded into to the ecosystem. There is a community of people here - how enguaged do “we” want to be in our network effects?
Some concepts I’ve been broaching for some time
