Since the inception of Bitcoin in 2008, thousands of cryptocurrencies or decentralised blockchains have been launched. Most ventures into the crypto sphere have not gone to plan as their founders would have hoped. Nevertheless, there are currently hundreds of crypto related projects which are succeeding. This book covers the history of Denarius, an open source, publicly distributed cryptocurrency. It was launched on the 14th June 2017. Carsen Klock, the founder and lead developer, vowed to “follow the footsteps” of Bitcoin by implementing its core code into Denarius. He implemented the same trusted blockchain technology whilst significantly decreasing the block time for a much faster network.
