Blockchain Explained: The Background Behind the Buzz

Blockchain is a data structure used to create a digital ledger shared among a distributed network of computers.

In plain English, a blockchain reverses the way computer networks work and helps to make them more secure.

Currently, computer networks connect to a central hub where information is stored. In blockchain, the information is stored on every computer in the network, simultaneously.

The information is updated frequently, ensuring that all computers in the blockchain have the same data. This is what makes it more secure and nearly impossible to hack.

Blockchain was initially designed for the peer-to-peer exchange of the virtual currency bitcoin. Now businesses are developing and testing some potentially game-changing blockchain applications.

Here’s an introduction to blockchain and a glimpse into how this emerging technology might impact the future of businesses around the world.

Control by consensus
Blockchain provides all network participants with simultaneous access to a single body of strongly encrypted data. Each individual (or node) can enter new data, but a majority of nodes on the network must verify the addition before it becomes part of the permanent record.

Each transaction is time stamped and linked to the prior transaction, forming a series of blocks in a digital chain. This creates an audit trail each time data is changed, helping to ensure the integrity and authenticity of the information.

Because no third-party intermediary (or central authority) is needed, transactions can be completed instantaneously and at a lower cost.

Realm of possibility
A blockchain can be public (open) or private (closed). Any system or business that relies on a database could be a candidate for blockchain-based innovation. A blockchain can also be coded to execute or enforce smart contracts automatically (without an intermediary) when certain conditions are met.

Here are a few examples of applications that are already in the pipeline.

Financial markets: The financial industry is identifying how the technology could be used to protect sensitive data, increase speed and cut costs for electronic payments, securities trading and lending. Since 2015, more than 100 financial institutions, trade associations, regulators and technology partners have joined forces to set up and test a blockchain that could one day become an industry-wide platform.

Supply chains: Each link in a company’s supply chain could be held accountable by tracing products from origin to store, discouraging tampering and fraud. This could enhance food safety, reduce the costs associated with recalls, and help retailers verify authenticity. For example, customers could be assured that their food was raised on an organic farm or that a specific diamond did not come from a conflict zone.

Medical records: Blockchain systems are being designed to store health data that can be conveniently shared among patients, doctors, hospitals, and insurers while protecting patient privacy.

Digital rights: Musicians, photographers, artists, and media businesses could more easily monetize, track, and control the use of their creations, which could reduce piracy.

Some other possible uses include public real estate registries, identity verification, law-enforcement activities, digital voting platforms and securing Internet-connected devices.

Work in progress
Businesses and governments worldwide are exploring blockchain technologies as they seek to improve transparency, increase productivity and reduce costs. As a result, investment in blockchain initiatives could approach an estimated $700 million this year. Numerous industry consortia are working together on business solutions for their shared interests, while some individual companies are racing to influence what might become common industry standards.

Despite the heightened levels of interest and investment in blockchain, deployments are still fairly rare, and widespread adoption could be years away.

In the longer term, however, blockchain could be a transformative and/or disruptive force that creates a new set of winners and losers.

Speedy and successful implementation may deliver a competitive advantage to some companies while punishing others that don’t keep up with the pace of change. There may also be some societal costs, such as high energy consumption from running millions of powerful computers, and the technology’s potential to displace a large number of human workers.

Word of warning
As an investor, you should keep in mind that new technology ventures are often risky. Some blockchain projects may turn out to be viable and profitable, but many others could fail. Bad actors are also trying to capitalize on the blockchain buzz by luring investors into highly speculative investments and some outright scams.

Thus, you should be wary of a company’s claims regarding blockchain – especially if an investment offer is unsolicited and Internet-based – and never wire money to pay for such an offer.
