So far, the entire crypto movement has been a lot, but not 100% sustainable. Numerous attempts have been made to use the electricity for mining with renewable energies. There were enough complications and problems. Now it’s finally over! The first sustainable blockchain called “Signum” is on the market. It serves as an intelligent platform and is therefore the complete solution for trading, mining and storing the cryptocurrency Signa. Signum produces virtually no electrical waste and consumes less than 0. 002% of Bitcoin’s energy.
