Why I Started Paying Attention to Blockchain

For the better part of a decade, I worked inside the machinery of global finance. Investment banking at Lehman Brothers, then mergers and acquisitions at UniCredit Bank Austria — deal after deal, I saw how capital moves across borders, how transactions settle, and how much friction exists in systems that most people assume are efficient.

They are not.

The plumbing of global finance is held together by decades-old infrastructure, manual reconciliation processes, and layers of intermediaries that each extract their fee. A cross-border wire transfer still takes days. Securities settlement operates on T+2 because the back-office systems cannot move faster. And the 2008 crisis revealed just how opaque and fragile the entire edifice really is.

The Spark

I first encountered Bitcoin around 2013, like most people in finance — with scepticism. Digital money created by an anonymous person? It sounded like a curiosity at best, a scam at worst.

But something changed in 2017. The conversation shifted from Bitcoin as digital gold to blockchain as infrastructure. Ethereum had introduced smart contracts — self-executing agreements written in code. Suddenly, the technology was not just about transferring value; it was about programming the rules of how value moves.

That distinction matters enormously if you have spent years watching how much time, money, and human effort goes into enforcing contractual obligations in traditional finance.

What I See That Others Miss

Most of my former colleagues in banking dismiss blockchain as a solution looking for a problem. I understand the instinct — the crypto space is noisy, full of speculation, and often divorced from economic reality.

But underneath the noise, something fundamental is being built. Consider what blockchain actually offers:

Programmable settlement — transactions that execute automatically when conditions are met, without intermediaries
Transparent ledgers — shared records that all parties can verify, eliminating the need for reconciliation
Borderless value transfer — moving money across jurisdictions in minutes, not days
Composable financial primitives — building blocks that can be combined to create new financial instruments

These are not incremental improvements. They represent a fundamentally different architecture for financial systems.

Enterprise Blockchain: The Wrong Starting Point?

The current enterprise blockchain movement — Hyperledger, R3 Corda, private consortium chains — is interesting but, I suspect, misguided. Banks are trying to capture the efficiency gains of blockchain while maintaining their position as gatekeepers. They want the technology without the disruption.

History suggests this rarely works. The internet's transformative power came precisely from its openness, not from the private intranets that corporations built in the 1990s. I suspect the same dynamic will play out with blockchain.

Where This Goes

I do not pretend to know exactly how this technology will reshape finance. The timeline is uncertain, the regulatory landscape is unclear, and the technology itself is still immature.

But the direction is unmistakable. The financial system is moving toward programmable, transparent, and globally accessible infrastructure. Whether that takes five years or fifteen, the trajectory is set.

I am writing this blog to document my thinking as I explore this space — not as a crypto evangelist, but as someone who has seen the limitations of traditional finance from the inside and believes that better infrastructure is possible.

The question is not whether financial infrastructure will be rebuilt. The question is who will build it, and on what terms.

This is the first in what I hope will be a regular series of posts exploring blockchain, fintech, and the future of financial infrastructure.
