Abstract: Embodiments of the invention are directed to methods, systems, and devices for replacing a token on a user device, such as a transaction card. The transaction card includes tokens representing an actual account identifier which is not visible on the transaction card. The transaction card may store a first token on a and include a digital display that displays a second token. When the first token or the second token is compromised, the compromised token is replaced without replacing the transaction card. When the second token is compromised, the compromised token is replaced with a new replacement second token using an electronic device. The replacement second token replaces the old second token on the digital display. After the second token is compromised and before the replacement second token is provisioned on the transaction card, the transaction card may still be used for transactions using other tokens provisioned on the card.

Abstract: Providing blockchain-based subscription-as-a-service management is disclosed. In one example, a node within a customer network begins execution of a subscription-as-a-service software instance. An activation agent of the node broadcasts an activation transaction, requesting activation of the subscription-as-a-service software instance, to other nodes of the customer network. A block-issuing node within the customer network, upon receiving the activation transaction, determines whether to activate the subscription-as-a-service software instance. If so, a block-issuing agent of the block-issuing node generates a blockchain block containing the activation transaction as part of a blockchain. The blockchain block is then broadcast back to the customer network, where it is eventually received by the node executing the subscription-as-a-service software instance. Based on the blockchain block, the node enables continued execution of the subscription-as-a-service software instance.
