In 2006 the founder of the biggest big data company Clive Humby declared that Data is the New Oil. Today our data is collected and sold by data brokers and since 2006 big data market has been increasing year by year.

In other words, our data is valuable to marketers and other agencies. In the past, data was distributed only from a single and analog source, but today cloud system uses for sharing data to users. Few big players collect data from users in order to share them with cloud technology.


Exchange Platform proposes a peer-to-peer data sharing system to make citizens active players in data market. It aims to bring together people who want to sell their personal data and people who need information. It is  a system that connects and monetesis social, financial, environmental and behavioural data.


Infrastructure layer: hardware and software devices (tools) that make the exchange possible;
Protocol layer: the rules and methods of exchange;
Application layer: the interface for users.

Exchange Platform works with the Blockchain technology to create a peer-to-peer, decentralised network. The decentralised transaction of data transfer, the transaction of spot market and the decentralised storage are made possible by the blockchain.


The value of data is calculated with an algorithm in real-time. The spot market algorithm is based on the supply demand. The supply is the number of data hunters, while the demand is the number of data wanters. When the supply decreases, the value of data increases in real time.

Exchange Platform is a project of IaaC, Institute for Advanced Architecture of Catalonia developed at Master in City & Technology in 2016 by:
