Blockchain

The Blockchain technology defines a distributed transaction ledger, decentralized, immutable and encrypted to keep track of the history of transactions. Transactions effected by the participating nodes to the protocol, are placed within blocks connected to each other through a system based on hash pointers. In fact, within each block you can find a pointer to the previous block (through use of hash pointer), thus implementing a chain of blocks (block-chain) immutable. The inclusion of a block within the Blockchain requires validation by special nodes in the network, in order to maintain a unique structure and universally recognized. The block validation mechanism ensures system reliability and avoids tampering once in the register. The register can be viewed as a distributed database, but unlike traditional DBMS, the system architecture makes use of peer-to-peer technology (P2P), requiring therefore centralization of data.

The register can be programmed to store any type of digital data, from one currency such as Bitcoin, pioneering use of Blockchain, to smart-contract, an ownership certificate, medical records, etc. Precisely because of this multi-sectoral adoption, in conjunction with the reliability, transparency, finality and solidity, it is provided important revolutions in areas such as finance, healthcare, energy, sales and many others.

The Blockchain technology is proposed as a new generation tool to initiate decentralized services where each node has a copy of the register, thus eliminating single point of failure because of the presence of data replicated on multiple nodes, storing and recording all transactions take place within the network, without the need of a trusted third party entity. It not is managed by a third party central but residing on the machines of the network nodes, the register provides resilience while also allowing you to retrieve information of transactions quickly and without the need of network connection.

In today's world, the digitization involves a countless types of services and security of information systems assume critical importance: thanks to the cloud computing phenomenon, often we rely on third-party entities for interaction activities or the management of resources digital (eg. cash, stock exchange, online shopping, saving personal data, etc.), and must be considered that these third parties may be victims of malicious hacking activities, thereby resulting tampering with systems, impairment or dissemination of data. The Blockchain technology comes into play to resolve these problems through revolutionary capabilities that allow you to check at any time a transaction made. All this can be achieved without compromising the privacy of involved entities.
