Blockchain technology is often hailed as a revolutionary tool that could either make the world fairer or intensify competition, depending on how it is applied and who controls it. At its core, blockchain is a decentralized digital ledger that records transactions across many computers in a way that the recorded data cannot be altered retroactively. This fundamental characteristic offers both opportunities for fairness and challenges that may increase competitiveness or inequality.
One of the key ways blockchain can promote fairness is through transparency and decentralization. Because blockchain records are public and immutable, they can reduce corruption and fraud by making transactions traceable and verifiable by anyone. This transparency can empower individuals and smaller entities by providing equal access to information that was previously controlled by centralized authorities or intermediaries. For example, in supply chains, blockchain can ensure that products are ethically sourced and that all participants have access to the same data, potentially leveling the playing field for small producers and consumers[3][4].
Decentralization also means that no single entity has control over the network, which can democratize access to services. In industries like finance, blockchain enables decentralized finance (DeFi) platforms that allow people to lend, borrow, and trade assets without relying on traditional banks or brokers. This can increase financial inclusion for people who are underserved by conventional systems, offering a fairer chance to participate in the economy[4][6].
However, blockchain’s promise of fairness is not without complications. One major concern is that the technology can embed and perpetuate existing biases, especially when combined with artificial intelligence (AI). AI systems trained on historical data may carry biases related to race, gender, or socioeconomic status. When these AI decisions are recorded immutably on a blockchain, discriminatory outcomes become permanent and harder to correct. For instance, AI-powered lending protocols on blockchain might unfairly deny loans or impose higher interest rates on certain groups, and these decisions cannot be easily reversed due to blockchain’s unchangeable nature[1].
Moreover, blockchain’s transparency can create privacy dilemmas. While public blockchains make transactions visible to all, this openness can allow AI to analyze patterns and potentially identify individuals behind pseudonymous addresses. This raises ethical questions about how to balance transparency with privacy rights, which is crucial for fairness in digital interactions[1].
In terms of competition, blockchain can both increase and decrease it. On one hand, by removing intermediaries and lowering transaction costs, blockchain can foster more competition by enabling new entrants to participate in markets that were previously dominated by large players. For example, decentralized platforms in music or asset management allow creators and consumers to interact directly without gatekeepers, potentially disrupting monopolies and encouraging innovation[4].
On the other hand, blockchain can also intensify competition in ways that may disadvantage less sophisticated participants. In cryptocurrency trading, AI algorithms can analyze blockchain data faster than humans, exploiting market patterns and creating information asymmetry. This can lead to an uneven playing field where retail investors are at a disadvantage compared to those with advanced technology and resources[1].
The impact of blockchain on corporate governance also illustrates this dual nature. Blockchain can transform governance by making decision-making processes more transparent and accountable, potentially leading to fairer corporate practices. However, the technology’s complexity and the need for technical expertise may concentrate power in the hands of a few knowledgeable actors, which could increase competitive disparities within organizations and industries[5].
In summary, blockchain technology has the potential to make the world fairer by enhancing transparency, decentralization, and access to services. It can reduce reliance on centralized authorities and intermediaries, thereby democratizing information and economic participation. Yet, it also poses risks of embedding biases, privacy challenges, and creating new forms of competition that may favor those with greater technological capabilities or resources. The ultimate effect of blockchain on fairness versus competitiveness depends largely on how it is designed, governed, and integrated with other technologies like AI, as well as the regulatory and ethical frameworks that guide its use.
