If the problem of scalability or even the reduction of protocol congestion should be weighed, I find that there could be an improvement in the scalability of the blockchain by unloading part of the transactional load on separate chains. This can also contribute to the reduction of mainchain congestion, the growth in the use of the blockchain & therefore lead to faster & more reliable transactions in these 3rd world regions with limited Internet connectivity & higher latency so where demand for low-cost & efficient transactions is important, further, economic growth & job creation...

So, it would be better to conceive this change by focusing on the positive impacts of innovation & personalization, not the fact that it can benefit maxis or anything else evoking a contentious vote or indexing miners.
