GALLARDO, Ignacio; BAZAN, Patricia    VENOSA, Paula. Architecture of Certificates: form a hierarchical architecture and centralized to a distributed and decentralized. []. , 32, pp.49-66. ISSN 1646-9895.  https://doi.org/10.17013/risti.32.49-66.

The main efforts of recent years have focused on the problem of set a name securely to public keys, in fact, the scientific community has been gradually adopting the use of systems based in Public Key Infrastructure (PKI) in order to provide security services. However, that systems depend on the existence of a centralized and hierarchical method. This same problem is translated into the management of electronic commerce, which presents a central entity that must issue electronic currency to different users. In 2009, Satoshi Nakamoto creates Bitcoin: a peer-to-peer technology to operate without a central authority or banks. This investigation applies in PKI the same concepts that Nakamoto applied in the electronic commerce, a reengineering and a paradigm shift, a migration from a centralized and hierarchical architecture to a decentralized and not hierarchical through the innovative technology called Blockchain.
