How the Internet and Blockchain Are Changing the World

The internet revolutionized the world by dramatically reducing the cost of information exchange to nearly zero. Before its advent, sharing information through mail, telephone, or fax was expensive. However, the internet made it possible to share information globally at minimal cost, provided there’s an internet connection. This reduction in information asymmetry transformed previously unviable businesses into profitable ventures.

Blockchain is set to bring about a similar revolution by reducing the cost of trust to near zero. Traditionally, transactions required trusted intermediaries to ensure credibility. For example, when lending money, we rely on banks to guarantee the borrower’s credibility, paying fees for this service. Blockchain eliminates the need for such intermediaries by ensuring seamless transactions within the system, regardless of the participants’ identities or intentions. This dramatic reduction in the cost of trust will enable new businesses that were previously unimaginable, much like how the internet created opportunities by lowering information exchange costs.

Let’s look at some real-world examples to better understand this transformative potential:

The internet’s impact is clearly seen in the rise of e-commerce giants like Amazon and eBay. Before the internet, shopping was primarily a physical activity, and the cost of reaching customers beyond local regions was prohibitively high. The internet lowered these barriers, allowing businesses to reach a global audience with minimal costs. Now, a small business in a remote part of the world can sell products globally, competing with much larger enterprises. This shift has democratized commerce, spurring a new wave of entrepreneurs and small businesses.

Blockchain’s potential is exemplified by Decentralized Finance (DeFi). Traditional finance heavily relies on intermediaries like banks and brokers, which charge fees and control access to financial services. DeFi platforms, built on blockchain technology, offer financial services like lending, borrowing, and trading without intermediaries. Smart contracts—self-executing contracts—ensure trust and secure transactions between users. This significantly reduces the cost of financial services and makes them accessible to a broader audience.

The impact of DeFi is already being felt in the financial world. As of 2024, the total value locked (TVL) in DeFi protocols has reached billions of dollars. Platforms like Aave and Compound allow users to lend and borrow cryptocurrencies directly, often at more competitive rates than traditional banks. These platforms operate 24/7, unlike traditional financial institutions, providing greater flexibility to users.

Another area where blockchain is reducing the cost of trust is in supply chain management. Traditional supply chains often suffer from a lack of transparency and traceability, leading to inefficiencies and potential fraud. Blockchain-based supply chain solutions provide end-to-end visibility of products as they move through the supply chain. For instance, Walmart has implemented a blockchain-based system to track the origin of food products, enhancing food safety and reducing the time it takes to trace the source of contaminated food from days to seconds.

In the realm of digital identity, blockchain is also making significant strides. Traditional identity systems are often fragmented, insecure, and controlled by centralized authorities. Blockchain-based identity solutions allow individuals to have greater control over their personal data while providing a more secure and efficient way for organizations to verify identities. This has the potential to reduce identity fraud, streamline KYC (Know Your Customer) processes, and provide identity solutions for the unbanked population.

The art world is another sector being transformed by blockchain through Non-Fungible Tokens (NFTs). NFTs provide a way to prove ownership and authenticity of digital assets, creating new opportunities for artists and collectors. This technology is reducing the cost of trust in the art market by eliminating the need for intermediaries to verify authenticity and provenance.

In the realm of governance, blockchain is being explored for voting systems. Traditional voting systems often suffer from lack of transparency and are vulnerable to manipulation. Blockchain-based voting systems could provide a transparent, tamper-resistant method of conducting elections, reducing the cost of trust in democratic processes.

However, it’s important to note that while blockchain has the potential to dramatically reduce the cost of trust, it’s not without challenges. Issues such as scalability, energy consumption (particularly in proof-of-work systems), regulatory uncertainty, and the need for user education are all hurdles that need to be overcome for widespread adoption.

As we look to the future, the potential applications of blockchain technology continue to expand. From creating more efficient and transparent government services to enabling new forms of collaborative organizations (DAOs – Decentralized Autonomous Organizations), blockchain is set to reshape many aspects of our society and economy.

One area where blockchain is making significant inroads is in the real estate sector. Traditionally, property transactions have been complex, time-consuming, and prone to fraud. Blockchain can streamline this process by creating immutable records of property ownership and transactions. This not only reduces the time and cost associated with property transfers but also increases transparency and reduces the risk of fraud. Countries like Georgia and Sweden have already begun implementing blockchain-based land registry systems.

In the healthcare industry, blockchain has the potential to revolutionize data management and sharing. Patient data is often siloed in different systems, making it difficult for healthcare providers to access a complete medical history. Blockchain can create a secure, interoperable system for storing and sharing patient data, ensuring that healthcare providers have access to accurate, up-to-date information while maintaining patient privacy. This could lead to better patient outcomes and more efficient healthcare delivery.

The energy sector is another area where blockchain is driving innovation. Peer-to-peer energy trading platforms built on blockchain technology are enabling homeowners with solar panels to sell excess energy directly to their neighbors. This not only makes renewable energy more accessible but also helps to create a more resilient and decentralized energy grid. Companies like Power Ledger in Australia are pioneering this technology.

In the field of intellectual property rights, blockchain is offering new solutions. By creating an immutable record of when a piece of intellectual property was created, blockchain can help establish and protect copyright. This is particularly valuable in industries like music and publishing, where rights management can be complex and contentious.

Blockchain is also transforming the way we think about digital privacy and data ownership. With traditional online services, users often have to trade their personal data for access to services. Blockchain-based systems could allow users to maintain ownership and control of their data, choosing when and how to share it. This could lead to new business models where users are compensated for sharing their data, rather than having it harvested without their explicit consent.

In the field of education, blockchain could revolutionize the way academic credentials are issued and verified. Digital diplomas and certificates stored on a blockchain would be tamper-proof and easily verifiable by potential employers or educational institutions. This could streamline the hiring process and reduce credential fraud.

The gaming industry is another sector being transformed by blockchain. The concept of “play-to-earn” games, where players can earn cryptocurrency or NFTs through gameplay, is gaining traction. This is creating new economic models and blurring the lines between virtual and real-world economies. Games like Axie Infinity have shown the potential of this model, particularly in developing economies.

Blockchain is also being explored as a solution for digital content rights and royalty distribution. In the music industry, for example, blockchain could ensure that artists are paid fairly and promptly for streams of their music. Smart contracts could automate royalty payments, reducing the need for intermediaries and ensuring a more equitable distribution of revenue.

In the field of philanthropy, blockchain is increasing transparency and accountability. Donors can track exactly how their contributions are being used, reducing the potential for fraud and misuse of funds. This increased transparency could lead to greater trust in charitable organizations and potentially increase overall donations.

As blockchain technology matures, we’re also seeing increased focus on its environmental impact. While early blockchain networks like Bitcoin have been criticized for their high energy consumption, newer consensus mechanisms like Proof of Stake are significantly more energy-efficient. Ethereum’s transition to Proof of Stake, known as “The Merge,” marked a significant step towards more sustainable blockchain technology.

The intersection of blockchain with other emerging technologies is also producing exciting results. When combined with artificial intelligence and the Internet of Things, blockchain can enable new paradigms of machine-to-machine communication and autonomous systems. This could lead to more efficient supply chains, smart cities, and new forms of automated commerce.

Despite these promising developments, it’s important to acknowledge that blockchain technology is still in its early stages. Many of these applications are still theoretical or in pilot stages. The technology faces significant challenges, including scalability issues, regulatory hurdles, and the need for widespread adoption and understanding.

Moreover, as with any transformative technology, blockchain has the potential for both positive and negative impacts on society. While it can increase transparency and reduce fraud, it could also enable new forms of financial crime if not properly regulated. The pseudonymous nature of many blockchain transactions raises concerns about money laundering and tax evasion.

There are also concerns about the digital divide. As more economic activity moves onto blockchain-based systems, there’s a risk of excluding those without access to the necessary technology or knowledge. Efforts to increase digital literacy and access will be crucial to ensuring that the benefits of blockchain technology are widely distributed.

In conclusion, blockchain’s potential to reduce the cost of trust to near zero represents a paradigm shift in how we conduct transactions, manage data, and interact in the digital world. While it may take time for this potential to be fully realized, the groundwork is being laid for a future where trust is no longer a scarce and expensive commodity, but a fundamental and accessible aspect of our digital interactions.

Just as the internet created a new digital economy by reducing the cost of information exchange, blockchain is laying the foundation for a new trust-based economy. By dramatically reducing the cost of trust, blockchain is enabling new business models, enhancing efficiency across various sectors, and creating opportunities for greater financial inclusion.

The journey of blockchain technology is still in its early stages, and we’re likely to see many more innovative applications emerge in the coming years. As the technology matures and overcomes current challenges, its impact on reducing the cost of trust could be as transformative as the internet’s impact on reducing the cost of information exchange. The future of blockchain is not just about creating new cryptocurrencies, but about fundamentally changing how we interact, transact, and organize in the digital age.
