- 99% of your transaction are located in your town (quarter).
Incorrect.
Nevertheless the idea of partitioning payment systems by some sort of natural (if fuzzy) boundaries is reasonable.
I still prefer off-chain (possibly partitioned) payment systems with a single settlement chain though. Not sold on merged mining at all.
ok, if you do not like "natural boundaries" we can create corporate chains. :-)
a) local-Tesco-Sidechain
b) or you can use Coca-Cola-Sidechain
c) or use Free-Wifi-Geaks-Sidechain
d) ... some local drug dealer chain
I do not know exactly how to build TREE OF CHAINS what will serve all people needs .. but I know that it is possible and free market will choose what is important and what is not
I never said anything negative about natural boundaries. It is merged mining of multiple chains that is a sham, and also attempting to peg units of different assets (with different security, liquidity, network, etc. properties) to the same price.
I see nothing wrong with payment channels though. There doesn't seem to be any good reason to put routine micro transactions on a chain (side- or otherwise) at all.
