Consensus policies are defined for validation of included data and integrity detection policies for data already recorded in the Blockchain. The data is immutable, the transactions are stored in blocks with their cryptographic function or hash and each block is chained to the previous full block, creating a chain of data, which has historical dependence.

There is no centralised management, network and data are distributed across multiple nodes sharing the same information, where participants can transparently and quickly access all made transactions. There is no single failure point.

Transactions are recorded in physically independent data blocks, that are related to the preceding one by including the preceding block’s hash among it’s data. A block cannot be added, modified or deleted without it changing the hash, and thus, network users can read and record content, but cannot alter what someone else has previously recorded.

The information is common to all participants, and any new data added is instantly shared with all network nodes. Accessibility from each local node to the whole of transactions made, which are synchronized to all nodes in the network,  allows for real-time auditing.

The "Smart Contract" is a piece of software that runs automatically and simultaneously on all network nodes in the Blockchain, containing the pre-established conditions to be fulfilled, agreed upon by all the parties involved, and that guarantees the fulfilment of the agreements between the parties.

The automatic validation of the fulfillment of aggreements without involvement of third parties thanks to the Smart contracts, added to the fact that the documents and details of the transaction are supported on the blockchain, makes the process more efficient due to the significant reduction of human errors and the shorter verification and validation times.
