If you’re in the banking or healthcare industry, you’ve likely heard the term “blockchain.” On the surface, this technology behind the exchange of bitcoin may not be taken seriously because some think that bitcoin, now valued at $41 billion, is a passing fad. But as the framework that makes bitcoin exchange possible, blockchain provides an innovative level of security that allows anonymous people who do not know each other to exchange money, without the traditional safety net (or fees) of a bank acting as a middle-man to authenticate funds transfers. And since this solution has opened up so many possibilities within the financial sector, many other industries are preparing for how blockchain can fundamentally change the way we all do business.
Imagine it’s 1992. Think back to what the internet was to you at that time. During this year, the first readily-accessible browser of the “World Wide Web” was launched. At the time, how would you have explained to people what the internet was?
In 1992, the internet was described as "a wide-area hypermedia information retrieval initiative aiming to give universal access to a large universe of documents.”
HUH? Sure, this description is technically true, but in 1992 this didn’t even begin to scratch the surface of what how the internet would fundamentally change daily life for us all in 2017. In the ‘90s while we would wait 15 minutes to dial-up to the World Wide Web or wait 10 minutes for a picture to download, it would have been hard to imagine a day when we would do most of our banking, shopping, reading and communicating online.
Today is not so different from 1992, because we still have the same difficulties describing new technology and envisioning how it can change our lives as we know it. In the context of bitcoin exchange, blockchain creates an encrypted peer-to-peer network where every single bitcoin transaction is recorded and validated throughout the entire network. This is different from our traditional model of transferring money from one account to another, where we rely on a bank (a central location) to verify that originating funds are available, to guarantee the safety of the funds while they are in transit, and to ensure that these funds reach the destination account as intended. Today, banks act as intermediaries for financial transactions, which allows us to trust in the safety and security of our money as we transfer funds.
Blockchain is a solution that also allows us to trust in the exchange of money, only the process works differently. The blockchain is referred to as a “ledger,” a series of records of validated monetary transactions, where the identical updated ledger resides throughout the peer network, not in one central location as under the traditional banking model. The system of blockchain is characterized by a few unique attributes that make this solution uniquely secure and positioned to transform many types of traditional business transactions:
- Distributed: This describes the fact that the ledger exists throughout the blockchain network, and is not maintained in one central location.
- Smart Contracts: We can think of this as an automated execution of a legal contract that governs the rules of each financial transaction.
- Consensus: In order for each transaction in blockchain to take place, “consensus” prevents fraudulent transactions by ensuring the validity of each transaction and agreement between parties of the transaction.
- Immutability: The record of a transaction in blockchain lives forever and it cannot be erased. The benefit of the inability to erase a transaction is that one single asset can be tracked throughout its entire life. In this sense, if a bitcoin were a dollar bill, the blockchain would track where and when the dollar was printed, who the first owner of that dollar was, and it would record every single date and exchange of hands along the blockchain, and none of these transactions could ever be erased.
Today, blockchain is a solution looking for problems to solve. The healthcare industry has high hopes for blockchain technology since interoperability, or the ability to securely share medical records across providers and patients, is the driving force behind many technology investments within healthcare. It’s widely believed that blockchain will be the technology that will form the basis of securely creating and sharing medical records that will solve many of healthcare’s current issues of siloed stores of data that lead to the delays and administrative burden of sharing health information. Designing an overlay of blockchain throughout the healthcare system reimagines a world without duplicate paperwork, inefficient payment systems, and delays in sending health records from provider to hospital, and these improved processes could all take place with a superior level of security.
Just as the internet was to 1992, so is blockchain to 2017. We're just getting started, and we can barely describe what is to come. This technology is indeed already transforming some industries, but in relation to identifying new ways it can enhance transaction security, prevent fraud, remove “middle man” fees, automate legal agreements, and increase the speed of information-sharing, we have yet to scratch the surface.
