BLACK & WHITE VERSION Peercoin (PPC) is a decentralised cryptocurrency similar to Bitcoin. It was the first cryptocurrency to introduce a new form of timestamping (proof of stake) that allows users of the wallet to receive a 1% rate of return on their holdings per year. This book is a detailed history of the first year of Peercoin up to the 19th of August 2013 (the time at which the blockchain had been usable for one year by the general public).
