Has blockchain found a use beyond crypto trading?

The bitcoin boom spawned new billionaires and videos of beach parties and Lamborghinis. The crypto crash brought devastation for small investors and bankruptcy for many companies. Blockchain technology underpins crypto and has been hailed as a world-changing innovation, but does it have any use beyond creating speculative financial instruments?

Crypto critic Stephen Diehl, the author of recently published "Popping the Crypto Bubble", runs the rule over some of the most popular claims made for blockchain technology.

As tension and confusion engulfed the United States after the 2020 election, Changpeng Zhao, the billionaire founder of crypto firm Binance, had a suggestion.

Fellow crypto billionaire Vitalik Buterin replied that there were "significant challenges" but he thought it was "directionally 100 percent correct".

So far, experiments have been very small scale. For Diehl, blockchain was more likely to introduce problems than solve them. From the American perspective, every single district runs its own voting program. This is seen as a feature because to corrupt any one election you would have to corrupt many, many civil servants. Centralizing the voting system in one digital place would be pretty risky then all you have to do is corrupt the blockchain and you could corrupt democracy.

Blockchain at heart is a ledger, a way of storing transactions that is according to fans secure, transparent, and permanent. Those qualities have led countless enthusiasts to propose that the technology could in effect replace paper contracts for things like house buying.

Diehl said it was "absurd" that the blockchain was going back to things that were solved a millennium ago to justify its own existence. This is the system we've had since the Middle Ages you have a government registry of land, a title, and a deed that gets transferred when the ownership changes. The blockchain isn't solving anything here.
