Years ago we could not imagine that technology could lead us to develop such great projects and discoveries as we have today. However today we are in an era in which we allow ourselves to talk about a technology that allows transactions of any kind in a reliable and safe way, which can be done between two or more people without the need of intermediaries, and through the Internet, and its name is Blockchain.

Blockchain was created by Satoshi Nakamoto in 2009, and introduced its first platform through the cryptocurrency, Bitcoin. This is known as ‘’digital money’’ and was created as a peer to peer electronic cash system. The name originates due to the way of functioning of this digital accounting, which consists in noting all the transactions that happen in the network grouped in blocks, then they are linked linearly to each other. This is the first block with the second, and thus successively. In addition, we have digital portfolios that are graphical interfaces to interact with the blockchain network allowing users to make transactions and manage their digital identities. The miners is computing power in charge of authorizing the addition of the blocks of transactions that the digital portfolios make to the chain of blocks, by solving the mathematical conundrum of the consensus protocol. They receive rewards in the digital currency of the blockchain network. Finally, the network guardians known as nodes, which are computers in charge of storing an exact copy of the accounting book and enforcing the rules of the network. Some, known as mining pools, are also in charge of listening to new transactions and grouping them in blocks to propose them as works to the miners, who after being confirmed are propagated to the network and added to the chain.

The blockchain technology guarantees that the records of the transactions made are valid and unalterable. Therefore, they are characterized by their immutability. However, there are initiatives to create blockchains that can be altered by an administrator, the company Accenture is the most well known user of this method. It should be added that because the power is not centered on a single part, but distributed among many parties that must reach an agreement, it is attributed the character of being decentralized.

Blockchain has been divided essentially into two categories and four types. We have the one based on the access to the stored data, in which we can find the public one, which is based on the no restriction for the reading of data or the realization of the operations by the users; and on the other hand the private one in which both reading and operations are limited to specific participants.

OpenBrix is a decentralized open source property portal, where Property Owners can sell and rent their property, collect money and manage transactions without paying any fee to a centralized intermediary. Should they wish to, they can hire the services of Property Managers / Estate Agents to do this for them. OpenBrix seeks to end with the centralized structure that has always allowed one group to exercise control over the rest of the network. Therefore they decide to use blockchain technology to achieve decentralization in the property portal business and offer the market an open and secure network that has been never seen in the world.
