Expert Witness Blog
Most crypto lawsuits I see labeled “cryptocurrency disputes” are not really about cryptocurrency at all. They are about hardware, power, cooling, and site operations. That is Layer 1. It is the physical layer of crypto, and it is where most Bitcoin mining cases actually live.
Attorneys often hire a general crypto expert for these cases. That is a mistake. A blockchain analyst who traces wallets cannot tell you why a hosting site went down. A token economist cannot explain why an ASIC fleet underperformed its stated hashrate. A Layer 1 case needs a Layer 1 expert.
Here is what makes someone qualified to serve as one:
Real Operational Experience
Reading a spec sheet is not experience. A Layer 1 expert has run the equipment, built the sites, and stood in the container when things went wrong. I have personally deployed SB3000 containers, managed 60 MW of mining capacity at over 97 percent sustained uptime, and worked in Tier IV environments earlier in my career. When I review a case, I am comparing what happened against what I have done thousands of times.
Understanding Industry Practice
Most Layer 1 disputes come down to one question. Did the operator behave the way a reasonable operator in this industry would behave? Answering that requires knowing what standard practice looks like across sites, seasons, and hardware types. In one arbitration, the central issue was whether the plaintiff’s operations matched industry practice. They did not, and the record showed it. That kind of opinion only holds up when the expert has actual field experience to back it.
Plain Explanations Under Pressure
A good expert witness does not hide behind jargon. Judges, arbitrators, and juries need to understand what a hashrate is, why immersion cooling matters, and how a curtailment event affects revenue. I write and speak in plain terms because that is what wins cases. If your expert cannot explain their opinion in one clear sentence, the fact finder will not follow it.
A Track Record Under Cross-Examination
Depositions are where weak experts fall apart. I have sat for five of them and held every opinion I gave. I have also testified at trial in a federal case that ended in a defense verdict. Cross-examination tests whether an expert actually knows the material or has only read about it. Attorneys should ask any expert candidate how many depositions they have given and how those cases ended.
Balanced Case Experience
An expert who only works for one side loses credibility fast. My retentions are split evenly between plaintiff and defense work. That balance shows the courts and opposing counsel that I follow the facts, not the client.
The Bottom Line
If your case involves hosting agreements, uptime disputes, power costs, hardware performance, site build-outs, or curtailment losses, you are in a Layer 1 case. Hire a Layer 1 expert. The wrong expert can sink a strong case. The right one can save a case that looked weak on paper.
Layer 1 is where the physical world meets the blockchain. That is where I work every day, and that is where I can help. If you wish to learn more about the layers, check out: Choosing the Right Crypto Expert Witness – by Aviran Vargas
