Blockchains are often presented as revolutionary solutions to transform the global economy, promising transparency and decentralization. Yet, despite these ideals, the concrete results fall short of expectations. This article explores the various reasons why blockchains struggle to deliver on these promises, highlighting the economic challenges and power dynamics that emerge in this evolving ecosystem.
The tension between decentralization and transparency
In the architecture of blockchains, one of the main concepts is transparency. However, this transparency involves a complex dynamic where the visibility of transactions constitutes a major challenge. As observed by Associate Professor Hanna Halaburda, the radical transparency intended to ensure the proper functioning of blockchain systems ultimately creates an environment where each actor can interpret and exploit the information. Indeed, this visibility leads to unintended consequences that promote unfair competition and arbitrage between actors, undermining the initial intentions of decentralization.
The auction market and technological dominance
The competition to validate blocks on a blockchain can be likened to a kind of tournament, where the top performers benefit from a disproportionate dominance. Block validators who use advanced technologies and sophisticated algorithms are able to capture maximum extracted values, a situation from which only a few actors benefit. Consequently, small businesses and new entrants struggle to compete, thereby reinforcing the power of already established players. This inequality amplifies, leading to a gradual centralization of the ecosystem that blockchains were theoretically supposed to replace.
The emergence of private channels
In the face of this transparency, many institutional traders adopt methods to circumvent the queue on public networks. By opting for private communication channels, they ensure a more discreet and efficient execution of their transactions. This phenomenon, although it may seem a rational solution, recalls the opaque markets of traditional finance. Thus, rather than eliminating intermediaries as promised, blockchain redefines their role, making decentralization more fragile than it appeared.
A mathematical trilemma
Halaburda’s analysis highlights a trilemma deeply embedded in blockchain systems: it is impossible to conceive a system that is simultaneously transparent, accessible, and decentralized. The results show that there is an inherent tension between these concepts, leading to systems that, in the end, balance towards a centralized model. In other words, attempts to rethink the economy through such technologies often fail because they end up reproducing traditional power structures.
The romantics of decentralization face the reality of markets
The initial vision of decentralization, widely acclaimed, runs into the reality of the market where capital and technology often determine the winners. Far from the image of a financial democracy, the future may prove to be a hybrid infrastructure, dominated by a few players who manage to establish themselves through their technological edge. The promises of a world where every participant would have an equal voice are at risk of disappearing, giving way to a system where only the most powerful prevail.
Towards a mutation of intermediaries
As we observe a mutation of intermediaries in decentralized finance, the situation highlights the inadequacy between collective aspirations and economic reality. This phenomenon offers a new perspective on how blockchains might evolve. Many professionals are beginning to understand that, far from eliminating intermediation, the technology simply compels it to adapt to new rules of the game.
