Infographic: How the Blockchain is Powering Our Future

Published

on

The future is bright, and it’s driven by the blockchain.

Blockchain technology is already turning the financial industry upside down through its disruptive applications, but finance is only the tip of the iceberg. The blockchain’s true scope is in its ability to change the way you do things every day – like voting, travelling, or going to the doctor.

The Future of Blockchain

Today’s infographic comes to us from HIVE Blockchain Technologies, and it gives us a glimpse into the potential of blockchain technology beyond the world of finance.

How the Blockchain is Powering Our Future

While the blockchain is primarily associated with cryptocurrencies and the financial industry, the true potential of blockchain technology is much broader.

Innovative startups are already finding ways to leverage blockchain technology to give facelifts to nearly every industry imaginable, changing traditional practices to make way for new, disruptive business models.

It’s difficult to imagine an area of life that won’t lend itself to a blockchain-fueled upgrade.

Today’s Blockchain

In its current form, the blockchain works something like this:

  1. Party A wants to transact with Party B
  2. This transaction is recorded on the blockchain as a block of encrypted data
  3. This block is then broadcast to every participant in the blockchain network. The block itself is visible to all, but sensitive information is encrypted to protect the privacy of both parties
  4. Each participant on the blockchain checks the validity of the block, confirming that everyone has the same version of encrypted information to eliminate the possibility of tampering
  5. Once verified, the block is added to the chain. Once added, it can’t be moved, changed, or tampered with
  6. Now that the transaction has been verified, it proceeds as planned

Currently this technology is primarily used for financial transactions, but it can also be used to exchange information, contracts, and official records.

The Blockchain’s Limitless Potential

The unique design of the blockchain makes it ideal for situations requiring:

Security
Transactions are virtually tamper-proof. Because each participant on the network checks each block for consistency, trying to hack the blockchain would be like trying to sneak through a single door guarded by a hundred dogs. It can’t be done.

Transparency
Each block is visible to every member of the network, ensuring trust between parties.

Collaboration
Because a blockchain has no borders, it allows for secure collaboration between parties sharing any kind of transaction.

As a result of these traits, the blockchain has limitless potential in all kinds of applications.

Future Blockchain Uses

Here are just some examples of future blockchain uses.

Decision-making
The blockchain can be used in business and government to increase transparency between parties, reduce corruption, and streamline bureaucracy. Transactions are tamper-proof and open to the public eye, allowing everything from rental agreements to national elections to be made fair and equitable.

Healthcare
The blockchain has the potential to improve medical access and efficiency. By allowing patient records to be shared securely between healthcare providers, doctors can bring all that information together to improve their diagnoses and develop more holistic treatment plans for individual patients.

With the wealth of patient data collated on the network, blockchain technology can help to advance more sophisticated medical research, potentially curing diseases or providing insights for more effective treatments.

Identity
Identity theft could also become a thing of the past with blockchain and biometrics. All of your personal identity information – even your passport, educational records, and driving licence – can be securely stored on the blockchain. Because your data is linked to biometrics unique to you and impossible to forge, the information is safe from fraud.

But these are just some examples – and the blockchain will impact nearly every facet of our lives, allowing service providers collaborate with one another to give you unique, personalized service, when you need it.

Ranked: The Best-Selling Video Game Consoles of All Time

Video game consoles have changed drastically over the last 50 years. Here are some of the best-selling ones across the globe.

Ranked: The Best-Selling Video Game Consoles of All Time

In 1972, the first-ever commercially available home video game console hit the market—the Magnavox Odyssey. Players of the Odyssey had a choice between two built-in games that were stored directly in the device, and would use a joystick and dials as a controller.

Video game consoles have come a long way since then, and the console market has grown into a multi-billion dollar industry that’s expected to reach $72.67 billion in value by the end of 2022.

This graphic by Enrique Mendoza uses data from VGChartz to show the market leaders in the industry, by highlighting the top-selling video consoles of all time, as of May 8, 2022.

Nine Generations of Video Game Consoles

Before diving into the top-selling consoles, it’s worth taking a step back to touch on the evolution of home consoles to show how they’ve changed over the years.

We dug into the literature on the history of video game consoles, and found that most articles and blog posts on the topic cite nine different generations of devices.

Here’s a breakdown of each generation, and some of their most noteworthy systems:

1972: Gen One, Where it Began

Consoles in the first generation had pre-built games that were stored directly on the device. They include the Magnavox Odyssey and Atari’s Pong.

1976: Gen Two Emerges

In this generation, games were sold separately, rather than programmed into the device. Consoles of this gen include the Fairchild Channel F and the Atari 2600.

1983: Gen Three, the “8-bit Generation”

This era’s consoles typically had 8-bit processes which allowed for more advanced graphics for the time. A few notable consoles during this gen were ​​the Sega SG-1000 and the Nintendo Famicom, released outside Japan as the Nintendo Entertainment System (NES).

1987: Gen Four Elevates Handheld Gaming

Home consoles were released with 16-bit systems, meaning that audio and graphics improved even more in this era. But an arguably bigger moment for this gen was the emergence of the Nintendo Game Boy.

1993: The 3D Start of Gen Five

This generation saw the move away from pixels and towards 3D polygons. Some consoles like the Sony PlayStation started using CD-ROMs instead of cartridges, which stored more data at a cheaper cost and changed the industry.

1998: Gen Six and the Internet

At the start of this generation, the three major players in the console space were Sony, Sega, and Nintendo. By the end, Sega would be replaced with Microsoft as it launched the Xbox and helped popularize online console gaming.

2005: HD Graphics and Motion Controls of Gen Seven

On one side of the market, Microsoft and Sony were competing with high-definition graphics, faster processers, and different forms (Blu-rays or DVDs). But Nintendo’s motion-sensing Nintendo Wii arguably defined this generation, and the handheld Nintendo DS swept the market as well.

2012: Gen Eight’s Modern Consoles

Consoles of this era started having increased connectivity and processing power, with full HD an expectation. It was also an extremely long generation, starting with Nintendo’s unsuccessful Wii U and ending with the ultra-successful Nintendo Switch, widely considered the first hybrid console with three different ways to play: TV mode, handheld mode, or tabletop mode.

2020: Gen Nine and Beyond

So far, this generation has brought upgraded graphics (up to 8K resolution), larger games, and game-streaming capabilities. Devices in this gen include the Xbox Series X/S and PlayStation 5, which both use solid state drives to increase speed and performance, while Nintendo has yet to introduce a 9th generation device.

The Best-Selling Game Consoles

The best-selling video game console of all time is Sony’s PlayStation 2 (PS2). More than 157 million systems have been sold around the world since its launch in March 2000.

Despite the fact the PS2’s been discontinued since 2013, no other gaming console has managed to top it—in fact, the next closest actively-sold consoles, the PS4 and Nintendo Switch, are each more than 40 million units behind.

One major factor for the PS2’s success was its built-in DVD player. At the time, DVD players were very expensive, and in many places a PS2 was a cheaper and effective alternative. It was also one of the first devices to be “backward compatible,” meaning users could play most of their PS1 games on the PS2. This meant players didn’t have to buy a whole new library of games when they made the switch to a PS2, and Sony could tap into its existing customer base.

But while Sony’s PS2 is the top-selling console on the list, Nintendo has more top-selling consoles on the list—almost half of the consoles on the list are manufactured by Nintendo (11), while only seven are made by Sony.

What Will it Take to Out-Sell the PS2?

As the PS4 has started taking a backseat to the PS5 in sales and promotion, the current most-likely contender for the best-selling console crown is the Nintendo Switch. Early in 2022, it was the fastest console to sell 100 million units.

With lots of hype around the possibilities of AR and VR, it’ll be interesting to see what new features come with the next generation of gaming consoles.

Will future devices ever beat the PS2’s record-breaking sales? Time will tell. But for now, the 22-year-old console continues to hold its well-earned spot at the top.

Visualizing The 50 Biggest Data Breaches From 2004–2021

As our world has become increasingly reliant on technology and data stored online, data breaches have become an omnipresent threat to users, businesses, and government agencies. In 2021, a new record was set with more than 5.9 billion user records stolen.

This graphic by Chimdi Nwosu visualizes the 50 largest data breaches since 2004, along with the sectors most impacted. Data was aggregated from company statements and news reports.

Understanding the Basics of Data Breaches

A data breach is an incident in which sensitive or confidential information is copied, transmitted or stolen by an unauthorized entity. This can occur as a result of malware attacks, payment card fraud, insider leaks, or unintended disclosure.

The targeted data is often customer PII (personally identifiable information), employee PII, intellectual property, corporate data or government agency data.

Date breaches can be perpetrated by lone hackers, organized cybercrime groups, or even national governments. Stolen information can then be used in other criminal enterprises such as identity theft, credit card fraud, or held for ransom payment.

Notable Data Breaches Since 2004

The largest data breach recorded occurred in 2013 when all three billion Yahoo accounts had their information compromised. In that cyberattack, the hackers were able to gather the personal information and passwords of users. While the full extent of the Yahoo data breach is still not fully realized, subsequent cybercrimes across the globe have been linked to the stolen information.

Here are the 50 largest data breaches by amount of user records stolen from 2004–2021.

The massive Yahoo hack accounted for roughly 30% of the 9.9 billion user records stolen from the Web sector—by far the most impacted sector. The next most-impacted sectors were Tech and Finance, with 2 billion and 1.6 billion records stolen, respectively.

Although these three sectors had the highest totals of user data lost, that doesn’t necessarily imply they have weaker security measures. Instead, it can probably be attributed to the sheer number of user records they compile.

Not all infamous data breaches are of a large scale. A smaller data breach in 2014 made headlines when Apple’s iCloud was hacked and the personal pictures of roughly 200 celebrities were disseminated across the internet. Although this highly targeted hack only affected a few hundred people, it highlighted how invasive and damaging data breaches can be to users.

The Cost of Data Breaches to Businesses

Every year data breaches cost businesses billions of dollars to prevent and contain, while also eroding consumer trust and potentially having an adverse effect on customer retention.

A 2021 IBM security report estimated that the average cost per data breach for companies in 2020 was $4.2 million, which represents a 10% increase from 2019. That increase is mainly attributed to the added security risk associated with having more people working remotely due to the COVID-19 pandemic.

Measures to Improve Data Security

Completely preventing data breaches is essentially impossible, as cybercrime enterprises are often persistent, dynamic, and sophisticated. Nevertheless, businesses can seek out innovative methods to prevent exposure of data and mitigate potential damages.

For example, after the iCloud attack in 2014, Apple began avidly encouraging users to adopt two-factor authentication in an effort to strengthen data security.

Regardless of the measures businesses take, the unfortunate reality is that data breaches are a cost of doing business in the modern world and will continue to be a concern to both companies and users.
