Of these, 32 full papers and seven short papers were accepted, corresponding to a 21.9% acceptance rate. Revised papers appear in these proceedings.The surge in interest in cryptocurrencies heralded by Bitcoin has been reflected in the composition of the program at FC for several years. Since 2014, a dedicated workshop, the Workshop on Bitcoin and Blockchain Research (BITCOIN), has been held in conjunction with FC. Given the quality and quantity of research appearing in this workshop, the International Financial Cryptography Association (IFCA) Steering Committee, in consultation with current and past program chairs of FC and the BITCOIN workshop, decided to integrate the BITCOIN workshop into the main FC conference as a new blockchain track.
