Ripple CTO Emeritus Details Hidden Tech Keeping XRP Safe From Big Money - U.Today

The public acknowledgment by Charles Hoskinson, who described the XRPL architecture as “very elegant,” sparked new debates about the network’s actual decentralization. Ripple CTO Emeritus David Schwartz stepped into the discussion to explain how the ledger protects itself from covert capture by large corporations.

Schwartz points to a classic paradox - in cryptocurrencies, capital usually rules. Large corporations can afford expensive hardware and entire engineering teams, which is why their nodes and validators operate flawlessly and without interruptions.

How XRPL stops big tech from buying out the network

According to Schwartz, if the creators of XRP Ledger had focused only on achieving perfect technical stability, the network would have quickly fallen under the full control of a handful of IT giants. To prevent that outcome, Schwartz insists on attracting a large number of ordinary independent participants from different regions

But that raises a problem: what happens if their servers suddenly go offline because of internet outages or power failures?

To solve this dilemma, Schwartz and his team implemented the Negative UNL (Negative Unique Node List) mechanism. If a small independent participant suddenly goes offline, the remaining servers, through consensus, temporarily place that participant on a blacklist and continue processing payments quickly without waiting for them.

Schwartz emphasizes the “surprising detail” that this list cannot be turned into a censorship weapon. Even if large corporations colluded and deliberately added an independent participant to it, they still would not be able to strip that participant of voting rights.

This is only a partial exclusion, as Ripple CTO Emeritus explains that the mechanism disables only the technical function of confirming payments so the network does not slow down, while the node retains full political power. It can still vote against fee changes, oppose bad updates, and continue influencing the blockchain’s future.

In the end, as Schwartz concludes, large companies are physically incapable of pushing smaller players out of the system. The blockchain remains protected from technical failures while staying free from corporate capture.
