Interesting project.
The whitepaper seems to indicate there's not much brand new about this cryptocurrency, except their plans for an SDK to allow easy integration between traditional merchants and the blockchain network.
What seems most interesting to me is that they plan for this SDK to support all cryptocurrencies, not just SONDER. To quote the whitepaper:
At the first stages Sonder will act as an independent project, but its ultimate goal
is the development of the API (application programming interface) and SDK (software
development kit) that are convenient for other projects. So, if the online-store owner
desires to connect a blockchain based wallet to his marketplace our API set and SDK
will help to apply these features with the maximum simplicity.
At the last time, tokens are given a choice primarily because of their security
options. But using diferent cryptocurrencies is sometimes restricted by necessity to
move it among the exchanges. There is no exchange, which provides ability to buy
all the cryptocurrencies in one place.
Sonder Platform will provide possibilities of making payments between
members in any existing cryptocurrency. Besides, due to technical features, free
token swap will be available.
