“Understanding blockchains is tricky. You need to understand their message before you can appreciate their potential. In addition to their technological capabilities, blockchains carry with them philosophical, cultural, and ideological underpinnings that must also be understood.” (William Mougayar, The Business Blockchain)


Welcome back, dear blockchain enthusiasts, skeptics, and the curious-at-heart! In the first part of this chapter, we talked about the symbiotic relationship between peer-to-peer (P2P) systems and blockchain technology and explored the potential of this technology in the automotive industry. By now it becomes much clearer how blockchain serves as a tool for achieving and maintaining integrity in decentralized systems, which is a revolutionary development in so many other industries.

And remember, blockchain is more than just a digital ledger; it’s a democratic force, a veritable Swiss Army knife in the world of P2P networks. We can say that this technology is here to offer integrity and transparency in industries that are hungry for disintermediation — the word that promises to make middlemen a thing of the past.

Now that we’re all caught up, grab your beverage of choice and maybe your notepad; we’re continuing our journey down the rabbit hole of real-world applications where blockchain and P2P technology are breaking lots of shackles.

Bitcoin and Blockchain: The Dynamic Duo

The concept now known as blockchain technology was introduced in 2008 by an individual using the alias Satoshi Nakamoto. To this day, the true identity of Satoshi Nakamoto remains undisclosed. His paper, “Bitcoin: A Peer-to-Peer Electronic Cash System,” is considered the starting point of the modern blockchain-based cryptocurrency revolution.

William Mougayar synthesizes the key principles of the paper’s abstract depicting Bitcoin’s foundation (which we think it is an essential grasp for anyone looking to understand blockchain and its potential):

· Peer-to-peer electronic transactions and interactions

· Without financial institutions

· Cryptographic proof instead of central trust

· Put trust in the network instead of in a central institution

So the technology known as “blockchain” serves as the foundational framework behind Bitcoin and to further elaborate on Nakamoto’s original concept, Mougayar encourages the exploration of blockchain from three different perspectives: technical, business, and legal.

From a technical standpoint, blockchain functions as a decentralized database, maintaining a publicly accessible and distributed ledger.

In business terms, blockchain acts as a peer-to-peer exchange network, enabling the transfer of transactions, value, and assets without the need for intermediary parties.

From a legal perspective, blockchain authenticates transactions, thus serving as an alternative to previously trusted entities for validation.

Jumping back to the memory lane to 2009, BAM! Blockchain was thrust into the limelight, thanks to Bitcoin. Banks fell only to be rescued by taxpayer-funded bailouts. This opened the gate to blockchain-based cryptocurrencies like Bitcoin. A financial system that is by the people and for the people. No bailouts. No central authority. Just a network of computers running a secure, efficient financial realm. For those living under volatile regimes or shaky economies, blockchain presents a stable lifebuoy to hold on to. While Bitcoin waved its flamboyant flags into public consciousness, the blockchain technology was there to quietly power it all along. You can think of Bitcoin as the star, and Blockchain as his stage crew. Without the crew, the show won’t go on. Another way to see this duo is with Bitcoin being to blockchain what email is to the internet — a groundbreaking application, but merely the tip of the iceberg.

And while the first deployment of blockchain was indeed to keep track of Bitcoin transactions, it has yet to reveal the full range of its abilities. It’s not just a spreadsheet for digital currency; it’s a customizable stage where any kind of data dance can happen, from storing voting records to tracking organic bananas.

Blockchain in Modern Life: Not Just About Coins

Blockchain vs. Banks: The David and Goliath of the Financial World

Before blockchain, banks were the Goliaths: large, powerful, and pretty much unopposed. Now enter blockchain, the David armed with a sling of transparency and a stone of speed.

Traditional banking systems, for all their pros, are laden with bottlenecks. Funds transfers can take days, and after-hours operations are virtually non-existent. In contrast, blockchain operates on a continuous cycle, allowing for transactions that are both faster and transparent. So, why wait for your bank to wake up from its weekend slumber to process a check when blockchain doesn’t even know what sleep is? Imagine your transaction whizzing through in just 10 minutes, whether it’s a holiday or 3 a.m. on a Sunday. The economic implications are immense; European bank Santander estimates suggest that we could save up to $20 billion a year simply by adopting blockchain in the banking sector.

Currency: Stability and Control

Blockchain introduces a new paradigm for currencies, one that is notably different from the centralized structures of current monetary systems. Given that your assets on a blockchain are not stored with a central authority, they are less susceptible to systemic failures of banks or governments. This feature is not just a “nice-to-have” but a lifeline for individuals in countries with unstable economies or authoritarian governance.

Healthcare: A Prescription for Data Integrity

We don’t need to stress how crucial integrity and confidentiality of medical records are in healthcare. And with blockchain we can simply ensure that once a medical record is created, it remains unaltered and secure. This gives greater trust between healthcare providers and patients, and also opens the door for more data-driven medical analysis without compromising patient privacy.

Property Records: No More Red Tape

If you’ve ever dabbled in property, you know the headache of deeds, legal hoops, and archaic filing systems. With blockchain, each transaction is recorded in a way that is secure and easy to verify. This could make property disputes much easier to resolve and even pave the way for more fluid real estate markets.

Supply Chains: From Farm-to-Table to Blockchain-to-Table

Trust is hard to earn and easy to lose, especially in the food industry where supply chain inefficiency can cost lives. Blockchain doesn’t just restore trust; it rebuilds it, one block at a time. Know where your “organic” kale or “fair trade” coffee is actually coming from, all thanks to blockchain technology.

Voting: Making Every Vote Count

Blockchain can offer a highly secure and transparent platform for electoral processes. The key benefit here is that once recorded, the data cannot be altered or deleted. This ensures greater trust in the process and can potentially increase voter turnout, fostering a more democratic society.


Blockchain’s applications are as varied as they are impactful. From revolutionizing age-old systems to creating entirely new ways of doing things, its potential is a force driving both technological innovation and inspiration towards societal change. The blockchain revolution is not an event; it’s a process, an ongoing evolution that will persistently change the way we conduct business, govern societies, and even how we interact on a personal level.

In the chapters to come, we’ll further delve into more specific uses and case studies of blockchain technology that are currently disrupting traditional paradigms. So, what’s the take-home message? Blockchain is not the future; it’s the present, sculpting our future. And as for you, dear reader, your journey into understanding this groundbreaking technology is also just beginning.

Stay tuned. The best is yet to come.
