Because of Loki’s Service Node architecture, near instant transactions are possible. Blink enables the same transactions that would occur on the Loki mainchain to be confirmed before being included in a block, assuring both the sender and the receiver of the validity of the transaction and protecting the receiver against a double spend. Users will have the ability to pay a higher fee to send a Blink transaction which will confirm in seconds rather than in minutes. This opens up a range of new use cases for Loki where face-to-face payments become increasingly practical and online payments become easier to integrate.
