报告摘要：Modern development of cryptography especially the public key cryp-tography has enabled many exciting _nancial applications. In this talk, we shall start with describing several relevant cryptographical primitives such as some special digital signature schemes and secure hash functions. We shall then go over some examples of notable digital currencies including e-cash and bitcoin. Finally, in this presentation we will discuss the blockchain technology as well as e_cient computation of cryptographical primitives involved.
