Credit is the currency created by Terra-Credit to offer free and fast blockchain-based payments. The credit uses the Participation Proof, which allows any user to become a block producer. Block producers support the network and are rewarded with new currencies, so this function replaces traditional mining, which is expensive and complicated. It also has its desktop wallet where its holders of Credit currency can make stakes, through proof-of-stakes and receive a percentage as a reward based on the amount of coins received. Your transactions are also an important point to mention, as your blockchain is apparently quite fast with very low rates. A currency that is still growing but it is worth paying attention.
