BLACK & WHITE VERSION. Reddcoin (RDD) is a decentralised cryptocurrency similar to Bitcoin. It was the first cryptocurrency to introduce a new form of timestamping (proof of stake velocity) that allows users of the wallet to receive up to 5% rate of return on their holdings per year. This book is a detailed history of the first year of Reddcoin up to the 2nd of February 2015 (the time at which the blockchain had been usable for one year by the general public).
