In late 2008, an electronic payment system called Bitcoin made its way into the world. Created by an unidentified programmer (or group of programmers) under the pseudonym Satoshi Nakamoto, its main purpose was to allow the ability to securely move the aptly named cryptocurrency, bitcoin, without utilizing a central bank or third-party. The technology behind Bitcoin is blockchain, a database that maintains a continuously growing list of records called blocks. The blockchains are stored across a decentralized, distributed network of personal computers (nodes).
Benefits of Blockchain
- No single point of failure
- Not easily hacked or corrupted
- A single person, entity or company cannot control it
Due to the rise and success of Bitcoin over the last several years, blockchain technology is now a subject of research and evaluation by a wide range of government entities, corporations, and industries to improve efficiency and security.
The Chamber of Digital Commerce, along with the U.S. Department of Health and Human Services, recently a co-host at a blockchain Code-A-Thon, looking to the public to create ideas on how blockchain could approach the challenges of managing electronic health records, such as privacy, security and scalability. It was the first ever blockchain hackathon hosted by a government entity. Last year, the U.S. Postal Service conducted a study to better understand the technology and identify potential areas of interest.
Removing the Middleman
At the beginning of 2017, McKinsey & Company, a global management consulting firm for governments and NGOs, submitted a report regarding blockchain technology. They surveyed over 200 companies and discovered that out of at least 80 nascent, but real (non-bitcoin) opportunities to apply blockchain technology, nearly a quarter of them exist within the insurance industry, followed by the payments industry at 13 percent. In general, the Financial Services industry made up 50 percent of the total mix. Blockchain technology has the potential to disrupt this industry by removing the “middleman” and creating efficiencies through various parts of the value chain, such as payments, pricing, transfers, smart contracts, identity fraud and investments.
What Does the Future Look Like?
Looking further into the future, experts and researchers are predicting that blockchain will allow companies to be run only by algorithms, improve artificial intelligence, and track and manage IoT devices. Blockchain is essentially a ledger of encrypted data exchanges between it and other devices, web services, and human users, so it would also provide a way to track the unique history of your individual device. Imagine having smart appliances that communicate and set priority with one another to run at the most opportune time, minimizing electricity costs and keeping your appliances in good working condition. Or imagine having a vehicle that can run its own diagnostic tests, schedule maintenance – and pay the invoice.
The potential applications and benefits of blockchain have no limitations, but like any technology, there are still disadvantages and questions that need answering. One major disadvantage is that it requires constant power from several sources to run. For example, one article found that every bitcoin transaction requires the equivalent energy to power 1.57 American households for a day. And there are still uncertainties within financial industries on how to regulate and adopt blockchain policies. Bitcoin was unprecedented and modern currencies have always been created and regulated by governments. Nevertheless, blockchain seems to be on pace to become one the most powerful, game-changing technologies to date, disrupting industries and making processes more efficient, transparent, and secure.
