The man everything thinks is the creator of bitcoin gave a speech discussing the history of the technology

Nick Szabo, the man believed by many to be the creator of digital currency bitcoin, made a public appearance at a conference on Friday morning, discussing blockchain technology and his vision for the future of the cryptocurrency space.

Szabo was speaking at Devcon 1 in London, a conference dedicated to Ethereum. Bitcoin attempts to decentralise money by using a public ledger of all transactions called the blockchain; Ethereum attempts to do this to law itself, creating "smart contracts" based on a combination of cryptography and programming to enforce terms.

Although Szabo's talk - on the final day of Devcon - was billed as the "history of the blockchain," he didn't go too deeply into the nuts and bolts of the history of the tech.

Bitcoin was created in 2008 by Satoshi Nakamoto, a pseudonymous figure who many believe to really be Szabo. (Szabo has denied this, however.) In fact, Satoshi didn't even get a mention, and neither did most other major projects and developments in the cryptocurrency space since then, with the exception of Ethereum and some of Szabo's own work.

Mark Karpeles, the disgraced CEO of now-notorious failed bitcoin exchange Mt. Gox was featured on a slide about the dangers of centralisation - though Szabo made no explicit mention of him in his speech.

Instead, the focus was on the ideological predecessors of the technology, and where Szabo sees it heading.

At the offset, he framed it as the product of thinkers like the objectivist author and philosopher Ayn Rand, and economist and political theorist Friedrich Hayek.

Rand is famous for her vigorous defences of capitalism and espousal of selfishness as a virtue. Szabo admitted that he has "never finished one of her books," but finds her "very influential nonetheless."

As you might expect from a man believed to be the creator of a project to decentralise and privatise money, Szabo was consistently critical of any attempts at centralisation. Looking at the Russian Revolution, Lenin "only had to take over a few places to get a stranglehold on society" due to this centralisation: the railroads, the newspapers, and so on.

It's not just property, and society: "Physical wealth has not necessarily been very secure." Take gold, he suggests - the Aztecs "compelled tribute from the tribes." The Spaniards sacked the Aztecs. Francis Drake and pirates swooped in and took theirs. German U-boats sank British ships in WW1, preventing its transport.

Szabo mentioned a hack on US financial institution JP Morgan which is currently in the news, and which allegedly earned the perpetrators more than $100 million (£66 million), as a modern example of the dangers centralisation poses. Cryptography - "and in particular Ethereum" - helps solve that.

The logic is that "wet code" (as he describes traditional law) has huge drawbacks: It's vague, expensive, varies from jurisdiction to jurisdiction, and is "based ultimately on the threat of coercion." But "dry code" - AKA computer code and Ethereum - has none of these problems. It's precise as only computer code can be, cheap to deploy after initial outlays, is universally constant, and its security is based on the blockchain.

The vision is that instead of needing to call up your lawyer to draw up a contract on paper, you will instead turn to Ethereum as a platform on which to make records. You might use Ethereum to register the deeds to a property, or to establish the terms of a loan clearly, without the need for any middlemen.

Once it's on the blockchain, it's there for good, for anyone to see: Barring a fundamental problem with the software that would doom the entire project, it can never be deleted.

"In summary," Szabo finished, "let's try to think about security more broadly."

"Let's try to secure everything. Let's try to protect everything that's important to us."

Though Szabo didn't mention his alleged connection to Satoshi Nakamoto, that didn't stop Devcon 1 attendees commenting on it on Twitter:

Satoshi Nakamoto made fresh headlines earlier in November, when finance Professor Bhagwan Chowdhry announced that he planned to nominate the mysterious figure for the Nobel Prize in Economics.

However, nominations for the prize are, as a rule, kept secret - raising questions over what Chowdhry's public disclosure would mean for the validity of his nomination.

The Prize Committee is now going to "discuss the specific issue," Göran K. Hansson, secretary general of the Royal Swedish Academy of Sciences, told bitcoin news site CoinDesk.
