The article is like 90% filler content and the actual news is just one sentence which is the same as the title. We didn't get any details of what exactly they are doing, so judging from the title, it looks really weird - cryptocurrencies are already payment networks, how would they create a payment network for a payment network? And more importantly, why would people use it instead of sending BTC directly?
People here cheer it as some sort of progress, but I suspect it's an attempt to hijack the cryptocurrency movement, by creating this intermediary network that will be like a bank and a regulator.
What I think is that it is going to be a new tokens which would be used as a currency on the payment network. It is easier to keep track of and has a lot more transparency on the transactions.
