Yes, SQ announced yesterday that it would pilot a private blockchain based "digital wallet" for the KrisFlyer program. What it failed to identify was any justification for choosing to believe that:
1) The program is not already digital today (hint: it is);
2) The integration of specific vendors and customers is somehow eased by a technology platform designed for anonymity and broadly distributed participation rather than a centralized solution;
3) The operating costs of the new solution will be lower than existing technologies or that the development costs will be earned back in any manner.

This is buzzword BS, not a legit play to deliver value to either the program nor its members.
