Access to land titles and property rights The disruptive potential here lies in the ability to make land titles — and, in general, property rights — available to billions of people who are currently unable to legally register their property. Blockchain technology also permits significant time and cost savings in the registration process. A secure property registry built on blockchain can secure billions of dollars in assets and make a significant social and economic impact globally by addressing the rapidly growing demand for transparency and accountability. “If you take somewhere like Egypt, 90 percent of people have got houses, they’ve got a garden, but they’ve got no piece of paper to show ownership of that ... And without ownership of your property, it’s almost impossible to start a business or get a bank loan or anything,” Sir Richard Branson. This must be a core component of any poverty alleviation strategy in the third world. We need to produce growth and economic participation by removing expensive intermediaries, and reducing barriers to entry. Importantly, in the third world context, this technology is resilient to nepotism and corruption ‒ you cannot bribe or control the blockchain ‒ it just exists, and speaks the truth. Everyone gets to play We are just beginning to grasp the possibilities of linking the remaining two billion unbanked people into the global economy via technologies like bitcoin. Anybody with a smartphone and a few cents to spare gets to play. Being able to register property ownership in a cheap, reliable way will feed billions in tradeable assets into the system. These are people that even today’s low-cost banks would see little business case in pursuing due to the bank’s relatively high running costs. To borrow a phrase from consulting, the long tail is about to start wagging the hell out of the traditional economy dog. 26 MAY 2017 SA Real Estate Investor A QUICK RECAP ON BLOCKCHAIN T he applications are vast: from finance and banking, identity management, health records keeping and land registries - everything can be done more cost effectively, transparently and with a higher degree of fidelity. Blockchain can keep an immutable record of anything (including ownership of an asset). The powerful concept is that it does this in a global, decentralized manner. Anyone can store data in a database, but how do third parties with competing interests (say, two banks) agree on a single version of the truth? In practise, each bank keeps its own record of transactions, and cross-checks this with the counterparty’s version of events (with some level of automatic suspicion). Disputes are resolved in complicated ways involving further record-keepers in-between (i.e. clearing houses). All of this is onerous, slow and expensive - and all these people need to be paid, of course! So, what if they all just shared one database? Well that’s half the problem solved - but who gets to control this central database? It would be far too much concentrated power for a single entity or sovereign institution to have, and indeed a single point of failure in a vastly important system. This is where the genius breakthrough of a blockchain comes into its own - it is an append-only, globally distributed, highly resilient database. Developed to underpin Bitcoin in 2009, the key innovation is a peer-to-peer network of nodes (computer servers) around the world which store, validate and replicate a single version of the true transaction records. These nodes are a Financial Internet on top of the Internet, if you like. Anyone can download the software and run a node on their internet- connected PC or laptop. A cryptographic puzzle known as Merkle Root hashing guarantees the validity of the work done by these nodes. The nodes are rewarded with virtual currency tokens that are found (or ‘mined’) in the process. In the case of public blockchains like Bitcoin, there is no single corporate entity, or sovereign government or institution that controls the blockchain itself. It is like an ‘everywhere’ database that can only record new events - i.e. it’s history is fixed in stone, and indeed any change to its historical records would cause that version of the database to become immediately invalid. The Merkle Root hashes create thousands of digital fingerprints (and fingerprints of fingerprints) - using all previous records. Change one byte anywhere and your version of the blockchain will be rejected by the global network of nodes validating the integrity of the database.
