I was asked to be an expert witness for a divorce case where bitcoin was involved. This is a pseudonymous HN account not linked to my real world identity, but I'd been a developer of bitcoin core for 8 years at the time, and had cofounded a very well known bitcoin company. I've presented at multiple bitcoin conferences, and the lightning network was made possible due to changes to bitcoin I personally spearheaded. In fact the set of people this could describe is so small, I've probably blown my cover to someone reading this from that scene.

The expert witness called by the opposing side was someone I had never heard of, who had a certificate from "Blockchain University," and near as I can tell never worked as a software engineer anywhere, much less on bitcoin.

Guess which one of us nearly got disqualified for lack of credentials.

Expert witness testimony is such a joke.

I’ve thought about making a line of collegiate apparel with ornate lettering: SDU. When asked what “SDU” stands for, the wearer would reply, “Signaling Device University”.

I hear they’re Blockchain University’s biggest rivals

Were you at the first Bitcoin conference in 2013? We had a booth there.

I’m curious about the context of Bitcoin in this divorce proceeding. What was at dispute?

Yes I was in San Jose in 2013, if that’s the one you’re talking about (technically there was one conference earlier in Thailand, but nobody remembers that one). I was on a panel at the SJ conference.

The case I was consulted for was pretty bog standard “guy claims he lost his bitcoin in a hard drive reformat X years ago; wife claims BS and wants half of peak market value as of the highest historical price.”

Without getting into identifying details, I was able to use blockchain data to independently verify the guy’s claims. Traced transactions, found watermarking features tying them to specific wallet versions. Can’t actually prove that the keys were destroyed of course, but I did show the coins were being spent like crazy from one wallet on one machine, then all activity stopped right around when he claims he reformatted the computer, and the coins sit there on those same wallet outputs to this day, even with multiple market peaks in the intervening years, and many years between then and when he became aware of his wife’s intent to divorce.

That’s the way things go in court cases. Us software developers like to think that the law is a highly rational, proof based system. But in reality it basically comes down to “which story seems more believable” in the end, and being able to point to technical proof is the exception.

I was on the jury for a resisting arrest case and ended up as an alternate. The judge pulled us into chambers and we talked for about an hour. One of the things that he said that stuck with me was “Everybody thinks it is CSI in here. It’s not. People come here and they tell you [the jurors] stories and then you have to decide which are true.”

Yeah, all the lawyers and judges I've talked to hate CSI (the show) for what it has done to people's expectations. The legal system does not operate like it is portrayed on TV. It really does come down to "what story is more believable?"

Sometimes a story is more believable because there is incontrovertible physical evidence. Normally in those circumstances it'd never go to the court room though -- plea deal in criminal cases, settlement in civil.

It's possible that can’t actually prove that the keys were destroyed was the only legally relevant part of your testimony.

I can’t prove that you’re not DB Cooper. Does that mean you’re guilty?

The goal of expert testimony is not to find the best technical solution. The goal is to adjudicate a dispute. So yes, objective qualifications trump subjective ones, and that shouldn't be surprising or disappointing.

All of the qualifications you list amount to subjective evidence of clout in an obscure (to non-programmers) programming clique.

On the other hand, the certificate from a Blockchain University probably had a well defined curriculum and criteria for passing.

Is this serious?
