An IT Expert’s Guide to Cryptocurrency

For the past several years, everyone has been talking about the power of blockchain and the potential of cryptocurrency. But what do those terms actually mean and what’s their implication for cybersecurity?

The world is quickly adopting blockchain technology into more and more real-world applications. And lately, it seems everyone is talking about one of the most popular use cases — cryptocurrencies. With tech moguls like Elon Musk tweeting daily about Dogecoin, environmental organizations arguing that Bitcoin is consuming too many resources, and a slew of major enterprises investing in obscure altcoins, cryptocurrency seems poised to remain popular for quite some time.

So, what does that mean for your company?

Whether or not your company is considering investing in cryptocurrency — or if you’re outright steering clear of it all — your role as an organizational leader is to have a good understanding of new technologies that could impact your industry. That means understanding the basic principle behind cryptocurrencies: blockchain.

We’ve put together a guide on some key blockchain principles (especially as they relate to crypto-economics) to help you understand what’s what.


Reviewing Key Cryptocurrency Terms

The essential terms to know are:

  • Cryptocurrency: Cryptocurrency is a form of currency that is digital and decentralized. It can be used like any other currency, like a US dollar. However, unlike physical currency, cryptocurrency is entirely digital, meaning it uses encryption techniques to control the creation of digital monetary units and to verify fund transfers.
  • Blockchain: Blockchain is the technology that makes cryptocurrency work (it is not the currency itself). It is essentially a digital form of record keeping that uses blocks that build on top of one another to create an unchangeable, permanent ledger of transactions (or other data).
  • Blocks: Blocks are the groups of data in a blockchain. When it comes to cryptocurrency, blocks consist of transaction records as users sell and buy coins. Each block can only hold a certain amount of information, which means that when the block reaches its limit, a new block is created to continue the chain.
  • Coins: Coins are the representation of digital value that lives on a blockchain or cryptocurrency network. Sometimes the network and the coin both have the same name (like Bitcoin), but not always. For example, the Stellar blockchain has a native coin called Lumen.
  • Bitcoin: Bitcoin is the first and most valuable cryptocurrency. It was initially launched on January 3, 2009 and has seen its value grow steadily over the years, though it experiences frequent fluctuations.
  • Altcoin: Altcoin is any cryptocurrency that is not Bitcoin, from the second-most popular coin (Ethereum) to a coin with a tiny market value.


Cryptocurrency and the Decentralization of Finance and Applications

One of the main arguments in favor of cryptocurrency adoption is that it has the power to distribute power away from a central point. Blockchains are inherently decentralized since they require consensus from all users in order to function as opposed to relying on a central authority. As such, individuals have a greater ability to control their own transactions than they would with regular currency.

These capabilities give cryptocurrency two popular value adds:

  • Decentralized Finance (DeFi): DeFi is a system of software written on blockchains that makes financial products available on a public decentralized blockchain network. That means anyone can use them without having to go through a middleman like a brokerage or a bank. It allows sellers, buyers, borrowers, and lenders to interact on a peer-to-peer basis without an institution or company facilitating the interaction.
  • Decentralized Applications (DApps): DApps are applications that are deployed on blockchains to carry out actions without any intermediaries. They are completely free of control or interference from any single entity. DeFi activities are often completed using DApps.


Addressing the Common Concern: Bitcoin and the Environment

One of the most frequently asked questions about Bitcoin and cryptocurrencies is whether they’re bad for the environment. It’s true that Bitcoin is energy-intensive — but it won’t be forever. Concerns around energy consumption are valid, but keep in mind, technology evolves and these problems can be solved. And just because Bitcoin is energy-intensive, that doesn’t mean all blockchains are. With more attention being placed on the environmental impact of digitization, new ways of making cryptocurrencies more energy efficient are starting to come on the radar.

As of right now, the future of blockchain and crypto energy consumption comes down to the distinction between two models: Proof of Work and Proof of Stake.

Proof of Work is the high-energy consuming Bitcoin model. It’s used to determine how the blockchain reaches consensus. In other words, Proof of Work is a way for the network to make sure that transactions are valid and that no one is doing anything problematic, like trying to spend the same funds twice. It’s based on complex mathematical equations that can only be solved by powerful computers in a process called mining. It’s the reliance on these powerful computers that makes Proof of Work consume so much energy.

Proof of Stake is the new, lower energy alternative to Proof of Work that cuts out the advanced cryptographic puzzles that make blockchains like Bitcoin such high energy users. Not only is Proof of Stake lower energy, but it also offers a fairer, more equal mining system and more scalable transactions. All these benefits mean Proof of Stake is gaining in popularity, gradually reducing the environmental impact of cryptocurrency.


The Role of Blockchain in Cybersecurity

Blockchain is constantly evolving and one of the most interesting evolutions is its potential in the cybersecurity space. For instance, Blockchain technology can be used to verify cybersecurity activities like patching, firmware updates, and more.

Whether or not your company is investing in cryptocurrencies, as an organizational leader, you should be aware of how blockchain is impacting that space. Some ways cryptocurrency is entering cybersecurity is by addressing issues like:

  • Weak and unreliable passwords: Weak passwords (especially those used on social media) are a huge security risk. Blockchain technology can be used to create a standard security protocol that offers a better alternative even to end-to-end encryption. The technology could even be used to secure private messaging.
  • Edge devices: Edge devices offer many positive opportunities for businesses, but they have also been used by hackers as an easy way to gain access to larger systems. By decentralizing the administration of edge devices, blockchain technology can be used to secure these devices and systems.
  • Distributed Denial of Service (DDoS) attacks: Another major issue is Distributed Denial of Service (DDoS) attacks, which blockchain technology can help prevent by decentralizing Domain Name System (DNS) entries.

As blockchain technology continues to evolve, it will be exciting to see all these applications and more play out. But remember — even as promising and powerful as these technologies can be, the best cybersecurity plan is a mix of blockchain solutions along with the traditional measures that remain essential to maintaining cybersecurity.
