System and method of providing secured coupon redemption with reward distribution in a blockchain (BC) network. A merchant pays for coupon coins to the BC network. When a consumer attempts to redeem a coupon associated with a purchase order, both the merchant and the consumer digitally sign a redemption request and send to the BC network for validation. The request may contain an encrypted order, an encrypted consumer key and an encrypted consumer key, and both signatures. Upon successful validation, the BC network can execute a smart contract to deduct the coupon coin balance and issue reward in the form of BC ownership coin to involved parties.
