Note: For additional information regarding the use case in this challenge, please also consider reading the use case FAQ that documented questions asked during the October 17th, 2017 info session.

Background Information on BC Land Title & Survey Authority

Who is LTSA?

The Land Title and Survey Authority of British Columbia (BC LTSA) maintains British Columbia’s official legal record of private property ownership.  The LTSA updates the land title register each time a change is made to the registered title.

Changes are made to title when a property is bought or sold, a mortgage is paid off, or a registrable interest, such as a mortgage, is created, modified or released. Changes may also occur following the death of a spouse, divorce or marriage.

What is a land title?

A land title is an official record of who owns, or has a legal interest in, a piece of land.    The land title record includes a unique nine-digit parcel identifier (PID), a legal description (a textual  unique identifier for each parcel of land in the province that generally includes  lot number, plan number, survey system identifiers (e.g. Section, Range, Township, District Lot, District, etc.) and other text),  the registered owner(s) of title, registered owners of interests in land and various legal notations.

Advice for Developers

If you’re a web or backend developer with little or no knowledge of blockchain technology, congratulations – you’re about to go on a learning journey that will take you into an exciting new technical realm! Blockchain technology is one of the fastest growing areas of technical innovation around, and some even predict that it will be as transformative as the Internet.  Blockchain developers are in huge demand, so developing your skills in this area will definitely pay off.

To prepare for the day, we recommend that you review the following material and watch the videos by way of introduction, which will make you aware of the tremendous possibilities of this technology and to help you think about why, when and how it makes sense to apply blockchain technology to a given use case:

Then we recommend that you review some technical literature to get you ready to apply blockchain solutions to the given use case:




Advice for Non-Developers

Not an experienced coder but knowledgeable about blockchain technology? No problem!  Your knowledge will be invaluable in helping others on your team think through how blockchain can help address the use case.

We recommend you think about the following questions in preparation for the blockathon:

  • What problem or pain points in the use case would blockchain technology address?
  • Why would blockchain technology address this problem over and above another solution?
  • Is there a need to share data to which changes or updates are made via transactions?
  • Are there multiple stakeholders involved in the transactions or multiple organizations that want to contribute to a data source?
  • Is there some aspect in which there is an absence of trust or where trust is required between parties that don’t know one another or have reason to trust one another?
  • Is there a need for disintermediation and coordination without human intervention, such as when there is a lack of trusted intermediary/central gatekeeper to verify transactions (or desire to remove intermediary)?
  • Is there a need to track the provenance of transactions or assets so where they come from can be trusted?
  • Is there a need to ensure that data are immutable and present a source of consensual “truth” that everyone can agree on?

Advice for Domain Experts

Are you a domain expert, such as a biomedical researcher, but not a coder or knowledgeable about blockchain technology.  If so, we need your domain expertise to help us better understand the use case!

To prepare for participation, you may review the following material/videos to raise your awareness of the tremendous possibilities of blockchain technology and to help you think about why, when and how it makes sense to apply blockchain technology to a given use case in this domain:

We recommend that you think about the following questions to prepare:

  • What are the steps needed to complete the transactions/activities represented in the use case?
  • Who are the participants involved in these processes/activities?
  • How do these participants need to interact with one another?
  • Are those interactions across organizational boundaries?
  • Where is trust necessary in the process?
  • Where are central intermediaries needed in the process? Who are they? What would happen if they were eliminated?
  • How is data shared and updated in the process? Where is it stored?
  • Where are the pain points in the processes and activities? How could the processes or activities be improved to address these pain points? What are the benefits to participants and society if these pain points can be addressed?

Blockchain Technology Research and Other Use case Related to Land Registration

Questions Considering How Blockchain Technology and Digital Identities Can Be Applied to the Use Case

  • What aspects of the problems described in the use case can be addressed with Blockchain technology and digital identities?
    • Why would blockchain technology and/or digital identities be used to address these aspects rather than other solutions?
  • How can blockchain technology connect participants in the processes of each use case?
    • Who are the participants in these processes?
    • How do participants interact with one another?
  • How can blockchain technology and digital identities complement one another for each of the use case?
  • Where is trust necessary in the processes of both use case, and how can Blockchain technology and digital identities be utilized to create trust?
