With this type of architecture, any node is able to initiate or complete any transaction. The nodes can differ among themselves in the local configuration, processing speed, in bandwidth and in the amount of stored data. The database that contains the information is distributed among the nodes of the network. The transactions are all tracked and transfers of bitcoin, including public accounts of the nodes are encrypted through the use of the system of public key cryptography, mathematical algorithm that provides security and protection to the transmitted data

Contrary to what happens for the other currencies, bitcoin can not be falsified. The maximum amount outstanding is fixed and transactions, with regard to the quantities of currency, are all checked and verified. 4. Exchange and methods of use facilitated. The bitcoin can be exchanged easily and quickly on the net. 5. Custody and simplified reserved.
