Digital certificate does not reform, block chain to end

Digital certificates, as an authoritative way of identity authentication, often means high prices.

Block chain, with digital certificate authentication, encryption and decryption logic, can be conveniently applied to various occasions, closed-loop security, do not need to pass the central authority of the certification body, only need mutual authentication (consensus mechanism). In this way, the certification of the authority of digital certificates, if not open their ecology, how to ensure the next generation of identity authentication, we will not all go to choose a consensus mechanism, and continue to choose expensive digital certificate.

Beat you, but not you. I am afraid that the block chain and digital certificates will also have similar relationship.
