Decentralization: Beyond the Blockchain Hype

From a tech promise to a governance horizon

In recent years, the word blockchain has been used as a promise, a slogan, and, far too often, a conceptual shortcut.

Anyone who lived through the wave of enthusiasm between late 2017 and 2018 will remember it well: Bitcoin’s rapidly rising price, packed meetups, nonstop Telegram chats, conferences popping up everywhere. The dominant idea was simple: blockchain would change everything, quickly.

In 2018, that euphoria turned into an explosion of ICO-funded projects (Initial Coin Offering). Some were scams, others were built on interesting intuitions that did not connect with reality, and others got lost in technical solutions that looked brilliant only on paper. The pattern was not new. Something similar had already happened during the dot-com bubble in the early 2000s: in the end, only a few survived, the ones with sustainable models. Many lost significant capital, and some were openly defrauded.

In that environment, a mantra spread that was as simple as it was dangerous: to be innovative, a project had to “use blockchain.”

It did not matter whether it was needed. It did not matter whether it fit the problem at hand. It did not matter whether simpler, more efficient alternatives existed. If the word did not show up in the pitch deck, the project was out.

Over time, a more mature awareness began to take shape. The issue was not the technology itself, but the uncritical way it was being used. That is where DLTs (Distributed Ledger Technology) started gaining traction: solutions that were often more flexible, better aligned with real organizational needs, with more manageable costs, stronger privacy options and, above all, a degree of decentralization that could be controlled more easily. Historically, companies tend to like that.

And this is where it is worth pausing.

The real issue is not the technology

Blockchain and DLTs are tools, means to an end. Like a hammer or a drill, they can be extremely useful when applied to the right job.

The point is not the tool, no matter how sophisticated or fashionable it looks. The point is why you are using it.

In the Blockchain for Healthcare project, this distinction matters. Blockchain and DLTs can be relevant, and sometimes crucial, yet without a clear lens on decentralization they risk turning into technological noise. In this context, decentralization is not a slogan. It is an analytical criterion applied to data, processes, and governance models, especially in complex, sensitive domains such as healthcare.

So what do we actually mean today when we talk about decentralization?

An idea that predates blockchain

The concept of decentralization did not begin with Bitcoin.

In the 1960s, during the Cold War, Paul Baran studied communication networks with a very concrete goal: designing systems that could keep working even if a critical node was taken out. From that work came a distinction that would become foundational: the more control is concentrated in a few points, the more fragile a system becomes; the more it is distributed, the more resilient it gets.

With Bitcoin’s launch in 2009, that intuition made a conceptual leap. Decentralization stopped being only a technical property of networks and expanded into economic, financial, and even sociopolitical dimensions, to the point of embodying the idea of moving beyond a central authority. It also changed its role: it became an objective and, at the same time, a method for getting there.

This is the background for phenomena such as DeFi (Decentralized Finance) and, more recently, DeSci (Decentralized Science). Today the same question is emerging in healthcare: are we truly moving toward a DeHealth, a “Decentralized Health,” or are we still in an exploratory phase?

The control paradox

In a decentralized system, control is not concentrated in the hands of a few. It is shared across many actors. That makes these systems powerful engines of innovation, because it becomes harder to protect entrenched interests without merit.

A similar dynamic can be seen in the open-source world, which is often misunderstood. Open source does not mean free. It means readable and verifiable by anyone. That transparency redistributes control.

Here is the counterintuitive part: we tend to value what we can control directly. In decentralized platforms, value often grows when exclusive control is removed. What no one can dominate becomes more robust, more reliable, and, for that reason, more valuable.

It is a paradox we still struggle to accept.

When decentralization is not the answer

At this point, one clarification is necessary: decentralization is not always the solution. Treating it that way turns it into ideology rather than pragmatism.

There are contexts where centralization works better. A clear example is public procurement: a single contracting authority can negotiate better terms, standardize processes, and reduce waste.

So the real question is not whether to decentralize, but when to do it. Sergio De Prisco, co-founder of Accademia Decentra, framed this especially well by treating decentralization as a practical choice that makes sense only under specific structural conditions: multiple actors, belonging to different organizations, with potentially divergent interests, who need to exchange value or share critical processes, without a central entity capable of guaranteeing integrity.

Perhaps that is why decentralization is less a source from which everything begins and more a horizon to move toward: a direction, not a shortcut, to be assessed carefully case by case.
