Blockchain for Your Business

         Many people think of blockchain as a technology that’s powers bitcoin. While this was its original purpose, blockchain is capable of so much more. Despite the sound of the word, there’s not just one blockchain. Blockchain is shorthand for a whole suit of distributed ledger technologies that can be programmed to record and track anything of value from, Financial Transaction to Medical records Land Title

       You might be thinking,  we already have processes in place to track data. What so special about blockchain? Let’s break down the reasons why blockchain technology stands to revolutionize the way we interact with each other.

 

The way to track and store datas 

          Blockchain stores information in batches, called blocks, that are linked together in chronological fashion to form a continuous line: metaphorically, a chain of blocks. If you make a change to the information recorded in a particular block, you don’t rewrite it, instead the change is stored in a new block showing the x changed to y at a particular date and time.

Sounds familiar? That’s because blockchain is based on the centuries-old method of the general financial ledger. It’s a non-destructive way to track data changes over time.

Here is an example:

        Lets say there was a dispute between Ann and her sister Henna over who owns a piece of land that’s been in a family for years. Because blockchain technology uses the ledger method, there is an entry in the ledger showing that Adam first own the property in 1900. When Adam sold the property to Mali in 1930, a new entry was made in the ledger, and so on. Every change of ownership of this property is represented by  new entry in the ledger, right up until Ann bought it from their father in 2007. And Ann is the current owner and we can see the history in the ledger.

     Now, here’s where things really interesting. Unlike the age-old ledger method originally a book, then a database file stored on a single system blockchain was designed to be de-centralized and distributed across a large network of computers. This decentralizing of information reduces the ability of data tampering and brings us to the second factor that makes blockchain unique.

 

Creates trust in the business data

          Before a block can be added to the chain, a few things have to happen. First, a cryptographic puzzle must be solved, thus creating the block. The computer that solves the puzzle shares the solution to all the other computers on the network. This is called proof-of–work. The network that verify this proof-of-work and if correct, the block will be added to the chain.

         The combination of these complex math puzzles and verification by many computers ensures that we can trust each and every block on the chain.  Because the network does the trust building for us, we now have the opportunity to interact directly with our data in real-time. And that brings us to the third reason blockchain technology is such a game changer.

 

No more intermediaries

        Currently, when doing business with one another, we don’t show the other person our financial or business records. Instead, we rely on trusted intermediaries, such as a bank or lawyer, to view our records, and keep that information confidential. These intermediaries build trust between the parties and are able to verify, for example,

        “Yes, Ann is the rightful owner of this land”.

   This approach limits exposure and risk, but also adds another step to the exchange, which means more time and money spent. If Ann’s land title information was stored in a blockchain, she could cut out the middleman, her lawyer who would ordinarily confirm her information with Mali. As we now know, all blocks added to the chain have been verified to be true and can’t be tampered with, so Ann can simply show Mali her land title information secured on the blockchain. Ann would have considerable time and money by cutting out the middleman. This type of trusted peer-to-peer interaction with our data can revolutionize the way we access, verify and transact with one another. And because blockchain is a type of technology, and not a single network, it can be implemented in many different ways.

         Some blockchains can be completely public and opened to everyone to view and access. Others can be closed to a select group of authorized users such as your company,  group of banks or government agencies. And there are hybrid public-private blockchains too. In some, those with private access can see all the data, while the public can see only selections. In others, everyone can see all the data, but only some people have access to add new data.

            It is a combination of all these factors de-centralizing of the data, building trust in the data and allowing us to interact directly with one another and the data that give blockchain technology the potential underpin many of the ways we interact with one another. But, much like the rise of the Internet, this technology will bring with its all kinds if complex policy questions around governance, international law, security and economics.

         Here at the center for International Governance Innovation, we seek to bring trusted research that will equip policy makers with the information they need to advance blockchain innovations, enabling economies to flourish in this new digital economy.
