Buy Proof of Sale

As you probably known, there are different "Proof of X" type algorithms to secure a blockchain and guarantee that there is consensus in its transactions. Regardless of what type of proof is used, the participants in charge of the verification receive a reward for their work. Inspired by that concept, Proof of Sale has been created. The idea is to use this token to process all sales of the products developed for Indicator. Its independence allows it to be used as a control instrument to reward Indicator holders each time a sale is made through it.
