Abstract
Our world is changing and evolving more and more at the pace
of innovations and new technologies. The blockchain was made popular following
an article that The Economist magazine devoted to it at the end of 2015. We
hear more and more in the press about bitcoin, a virtual currency based on
blockchain technology. This end of studies project aims to popularize and
demystify, in an educational way, the functioning of the blockchain. We will
explain the main lines without having to be a computer expert to understand.
This technology has the potential to change the rules of the game for many
sectors, including the financial sector, starting with the banking system. This
new trust model based on a decentralized and shared system wants to replace the
existing trust intermediary. A new world is emerging. In this work we were
interested in the use of Blockchain for the management of operations on bank
transactions. The proposal provides a solution to the various problems related
to the theft and fraud of money based on transactions similar to the bitcoin
transaction.
Keyword: Blockchain, cryptocurrency,
bitcoin, ethereum, litcoin, transaction, computer security, banking network,
personal network, local network, metropolitan networks, cryptography, IP
addressing.
