Action Coin is being built on the NXT blockchain and will be launched on the Ardor Platform in March.
From the website:
The Action Coin Platform represents over 200,000 Action collectors and customers from more than 200 countries and territories. It is the basis of an incentive-driven rewards program with “points” that are rewarded in the form of a decentralized, blockchain-based digital asset known as Action (“ACTN”). Action may be redeemed for member-only discounts on a growing list of products and services offered through our business network.
