Blockchain and Future House Purchases

Second phase completed in march 2017

We are piloting the first project in Sweden to model a property purchase using blockchain and smart contract technology. The goal of the pilot is to evaluate the technology from a legal, business and IT perspective. The current phase of the pilot will be concluded on the 30th of March with the delivery of a functioning technology platform and a findings report.

We are delighted to announce the conclusion of the second phase of the real estate project, in which we successfully piloted our technology in a test environment. Now we are looking forward to developing the project further in the next phase.

    Sweden has always been a trailblazer with regards to legislation and handling of property data. First we had the registry on paper, in the '70s it was transferred into the digital domain with EDP (Electronic Data Processing) as it was called back then. We believe the blockchain is the new generation technology for our field of work and this project has reinforced the belief. We now start facing questions on how to get this into production.

    We have great hope in being able to save time and increase the strength of our offering, but also increase the security and control. Real estate transactions has been a forgotten track in the blockchain development but it is core for our business. As a small bank with a modern IT system, we have the possibility to be flexible and evaluate new technologies.

    It is an fantastic opportunity to cooperate and through cooperation create the next generation of technical infrastructure. Our business has a large range which makes us the ideal partner for digital innovation using future technology and we see blockchain as a technology with the potential to disrupt several industries by creating new ways to create secure, open and transparent systems that solve business and societal challenges.

    SBAB has the ambition to be an innovator within the financial sector especially in the mortgage space. We knew that blockchains meant an opportunity for big change. Now we are building better knowledge and understanding to be able to analyze how to best integrate this in our business and create the next generation of products and services.

    I’m fully convinced that blockchain will be the obvious solution for property transactions in the future. It’s really fun to see our work inspire projects around the world.

    ChromaWay are pioneers of blockchain technology. We develop solutions with a proven track record, delivering things that many even did not think were possible. The technology for property transactions we’ve built is a great platform for the future.

    Already during 2016 the Swedish Land Registry was active in 15 countries helping to develop and enhance Land Registry capabilities. Month by month we see an increased international interest in blockchain technology in the field. Last week I gave a presentation of the project at the largest conference on property related issues, at the World Bank. It’s exciting and rewarding helping other countries with something that is at the same time futuristic and of great benefit to society.

Background

The project started in 2016 when Lantmäteriet, Kairos Future, Telia Company and ChromaWay decides to investigate how blockchain and smart contracts could be used for real estate transactions. The property purchase process was quickly identified as an interesting use case together with the mortgage deed transfers. in June 2016 a demo (see below) showing the UI of how such a solution could look like as well as a report discussing the potential of this technology within real estate was released.

The project received a great amount of international attention and in August 2016 the second phase of the project started. Together with two new members SBAB and Landshypotek Bank the project members sat out the goal to build a pilot to test the technology from a business, legal and technical aspect. On the 30th of March 2017 the second phase concluded with the release of a second report talking about the results of the pilot as well as a fully functional technical solution.

Technology

The underlying technology for this project is ChromaWays two innovative products. First, Esplix the smart workflow middleware which enables processes and workflows to be described using code and then enforced by the participants in the system. Second is Postchain a consortium database technology which combines the capabilities of enterprise databases with private blockchains.

The demo

Below you can see a demo of what the future real estate process of the user could look like, this demo was developed during the first phase of the project Jan 2016- July 2016. If you want to know more about the underlying technology please see above.

We have five actors, each with an individual app. In them you can follow the view of each actor as a property purchase takes place. You can take the place of the buyer or seller of the property as well as the real estate agent, the bank or the land registry.

Start by logging in the buyer and seller, click login in the two top apps. We use the Telia ID solution to identify actors, in the online demo a simulation of this process occurs when you login or sign documents.

After logging in the seller invites the real-estate agent. Now focus moves to the three smaller windows below the apps, a button "accept invite" appears. The three smaller windows represent the Real Estate Agent, the buyers bank and the Land Registry. Typically they will have integrations with internal systems rather than buttons on a screen.

All clicks in the workflow open ups new steps. The kind of steps and who can make them are defined in a smart contract, and all done steps are signed and committed on a blockchain. All actors will see the same information, and have proof of all steps taken.

Blockchain

Our Smart Contract technology records state changes in a contract and then publicizes them on an underlying blockchain.

Below you can see the state changes as they follow the process of events that happen when you click in the apps above.

Report

Kairos Future have produced a new report in the form of a white paper which explains much more about this project.
